CHAPTER ONE
INTRODUCTION
Human behavior plays a
central role in the maintenance of health; health risk behavior can be defined
as any activity undertaken by people with a frequency or intensity that
increases risk of disease or injury (Baban & Craciun, 2007). The impact of
these risk behaviors on health is of such magnitude that it has become one of
the priorities of the most important national and international health
organizations (Baban & Craciun, 2007).
Adolescence is a
developmental period of physical, psychological, socio-cultural and cognitive
changes characterized by efforts to confront and surmount challenges and to
establish a sense of identity and autonomy, while many adolescents navigate the
sometimes turbulent cause from childhood to adulthood to become productive and
healthy adults, there is growing concern that too many others may not achieve
their full potential as workers, parents and individuals. Unfortunately,
adolescence is also a period of fraught with many threats to the death and
wellbeing of adolescents, many of whom suffer substantial impairment and
disability. Much of the adverse health consequences expensed by adolescents
are, to a large extent the result of risk behaviors that are preventable
(Diclemente, William, & Lynne 1996).
During the transition from
childhood to adulthood, adolescents establish patterns of behavior and make
lifestyle choices that affect both current and future health. Contemporary
threats to adolescents’ health are primarily the consequence of risk behaviors
and their related adverse outcomes, identifying factors associated with
adolescents risk behaviors is critical for developing strategies (Diclemete,
Wingood, Crossby, Sionean, Cobb, Harrington, Davies, Hook & Oh, 2001).
Adolescents take risk as a way of developing and defining themselves. They do
this by taking on new challenges in areas that they often understand very
little about engaging in behaviors with results that range from devastating to
extremely positive. Risk-taking is the major tool that adolescents use to shape
their identities. The term “risk” has a
negative connotation especially when it comes to girls. Girls’ risky behavior
elicits images of unsafe sex, drug use and criminality. Research on girls’
unhealthy behavior is plentiful. A simple literature search warns parents,
counselors and teachers about what can happen when girls step out of the box.
A
meta-analysis performed by Byrnes, Miller and Schafer in 1999 found after
reviewing more than 150 papers, across the board, men were more likely to
engage in risks than women. And in 2002 study done by Weber, Blais, and Betz,
women were found to be more cautious across different domains of risky
behavior, such as financial and recreational with the exception of social risk,
in which case there was no significant difference.
Adolescents
engage in risky health behaviors more than young children and adults. This risk
taking is thought to be a result of biological and environmental factors
influencing adolescent behavior. Teenagers’ engagement in risky sexual behavior
puts them at a higher risk for morbidity and social stress resulting from
unintended pregnancy and sexually transmitted infections. This increased risk
of morbidity emphasizes the public health significance of adolescent risk
behavior (Jean, 2010).
Consequences of health-Risk Behaviors include
sexually transmitted disease (STD) a name that actually covers all diseases
that are spread by sexual contact; with the discovery of antibiotics at mid
century, many physicians thought that the problem of STD or *VD-Venereal
Disease, as it was then called) could be cured once and for all. In fact, the
frequency of STD did decline during the 1956s, as infected people were cured
with penicillin before they could spread the disease. However, in the past
twenty years, the incidence of STD has taken a marked upswing, especially among
people under age 25, who now account for three fourths of all reported cases
(Green and Horton, 1982).
The
seriousness of this for the future of the young person should not be
underestimated; repeated STD is a leading cause of infertility. And in the case
of AIDS (Acquired Immune Deficiency Syndrome) even one exposed to this sexually
transmitted virus can lead to illness and death.
Adolescents
certainly do not need to be told that drugs are harmful to them. For most of
them, this message has come from the homes and schools since they were
children. For instance, 97% of all adolescents report that their parents would
be strongly opposed to their regular use of Marijuana or daily use of alcohol
and a majority report parental opposition to even one time use of most drugs;
given the adolescents inclination toward the imaginary audience and personality
table, some drug exploration is almost inevitable (Elkinid, 1984). Indeed, two
tenets of adolescent egocentrism- “I can handle anything” and “adults don’t
understand my experiences” are especially misleading for the adolescent trying
to think about drugs. For instance, the cognitive confusion characteristic of
regular marijuana use or the slowed reaction time after even one or two
alcoholic drinks are particularly difficult to spot if one believes one is
invincible.
Another serious consequence of adolescents’
health risk behaviors is unwanted pregnancy. According to the World Health
Organization (WHO, 2015) many adolescent girls between 15 and 19 years get
pregnant and about 16 million women 15-19 years old give birth each year, about
11% of all births worldwide. The proportion of births that take place during
adolescence is about 2% in China, 18% in Latin America and the Caribbean and
more than 50% in Sub-Sahara Africa while half of all adolescent births occur in
just seven countries: Bangladesh, Brazil, the Democratic Republic of Congo,
Ethiopia, India, Nigeria and the United States.
However, pregnancy among
very young adolescents is a significant problem. Although adolescents aged
10-19 years account for 11% of all births worldwide, they account for 23% of
the overall burden of disease (disability-adjusted life years) due to pregnancy
and child birth and the risk of maternal death is four times higher among
adolescents younger than 16 years than among women in their twenties, many
health problems too are particularly associated with negative outcomes of
pregnancy during adolescence, these include anaemia, malaria, HIV and other
sexually transmitted infections, post-partum haemorrhage and mental disorders
such as depression, up to 65% of women with obstetric fistula develop this as
adolescents, with dire consequences for their lives, physically and socially
(W.H.O, 2015).
However, few have examined
the impact of parental monitoring, birth order and gender in adolescent health
risk behavior. Historically and across diverse cultures, parents have been
identified as central influences in the development of their children.
Today, despite recent controversy over the
role of parents, considerable research indicates that parent-child relationship
is important in the lives of infants, children, young adolescents and teens (Hair,
Moore, Garret, Kinukawa, Lippman, & Michelsen, 2003). As central
socializing agents for children, parents provide emotional connections,
behavioral constraints and modeling which affect children’s development of self
regulation, emotional expressions and expectations regarding behaviors and
relationships. Theories about deviant and problem behavior have thus also
included parents as central elements in their explanation framework. Social
control theory, one of the most influential theories of deviance proposes that
parental bonding with children inhibits deviance or problem behavior by making
youth aware of the costs and effects of such behavior on their ties with
others.
Empirically,
research has found that good relationships with parents may protect youth from
initiating risky behaviors. (Liu, Fangmail, Zhou, Zhang, & Deng, 2013). Parenting
practices have been conceptualized as a system of dynamically interrelated
dimensions including monitoring (eg. Attention, tracking and structuring
contexts) behavior management (e.g. Negotiation, problem-solving, limit-setting),
and social cognitions (e.g, motivation, values, goals and norms), with the
quality of the parent-child relationship (eg. Trust) serving as the foundation.
However, when parent practices are examined for their role in health-risk
behaviors in adolescence, such as sexual activity or substance use, research is
often limited to a single dimension and most often, to the roles of parental
monitoring. The other possible dimensions (e.g. birth order and gender) have
been considered much less frequently, although these dimensions may serve as
important components of health risk prevention and management. (Barowski, Ievers-landis,
Lovegreen & Trapl, 2003).
As
children mature and gain independence, parents adjust their supervision
practices to allow for more freedom and independent decision-making by the
adolescent. Research has suggested that open lines of communication and
knowledge of an adolescents whereabouts (i.e, parental monitoring) are
important in reducing health-risk behaviors. It is also observed that there is
a significant interaction between parental monitoring and a number of adverse
life events, adolescents with high levels of parental monitoring reporting
lower levels of delinquency even at high levels of adversity. Parental
closeness is an important support and buffer for children living in contexts
characterized by high levels of adversity because the close ties between the
parent and child allow for greater-expression and enables parents to provide
better care for their children, in addition close parental monitoring may help
young people adjust positively when exposed to external stressors. (Kabiru,
Elung’ata, Mojola & Beguy, 2014).
Behavior
management approaches are also used by parents of older adolescents as part of
their general supervisory practices. However, such approaches have less clear
implications with regard to risk behaviors. For example, in later adolescence,
parents are more likely to allow their teen the freedom of spend increased unsupervised
time with peers, as part of a negotiated agreement between parent and
adolescents. As such, parents may allow their adolescent to “bend the rules” as
long as prior permission is granted for those exceptions. Additionally, parents
may believe that they can monitor their teen better if he/she entertains
friends at home rather than at different location (i.e. friend’s house). And in
exchange, parents often reduce the amount of direct supervision in these
situations by providing private space for the adolescent and his/her friends.
Although, these examples of negotiated unsupervised time with peers may
increase the adolescents’ decision-making and encourage a level of
parent-child, they may also lead to more opportunity for experimentation with
sexuality and substances (Barowski, Ievers-Landis, Lovegreen, & Trapl, 2003)
Jean
(2010) noted that “parental monitoring has been identified as important protective
factor for adolescents’ negative sexual health outcomes. However, the
distinction between rule and coercive discipline is critical in understanding
the influence that parents have over their adolescents risk taking behaviors.
Without recognition of the importance of a supportive and trusting
parent/adolescent relationship, parental monitoring studies and interventions
will be less effective in bringing about behavior change in adolescents and
their parents. Perceptions of parental monitoring can vary greatly between
adolescents and parents, and thus there is a need for a scale to measure actual
parental knowledge of adolescent risk behavior. It is also important to
consider the quality of parent and adolescent relationships when attempting to
understand the effects of parental monitoring. As a result the examination of
barriers to parental monitoring and the nature of parent/adolescent
relationship are crucial for making a last positive impact on adolescent sexual
health outcomes”.
Parents know that at a certain point in their adolescent’s
life, they must “stop relying on their own vigilance, discipline and control
and begin relying on their children’s responsibility and integrity”. This trust
is established through shared knowledge and communication often centered on
parental knowledge of their children’s daily atrocities and previous
demonstration of established responsibility on the part of the adolescent.
Research has shown that adolescents who perceive a strong mutual trust with
their parents are less likely to engage in high risk behaviors; however, much
less is known about the relationship between perceived trust and other risk
behaviors such as sexual atrocity or substance use. Thus, an important
foundation for parenting practices, trust should be examined in the context
of other dimensions of parenting to
determine its relative contribution in explaining adolescent health risk
behavior (Barowski et al; 2003).
According to Fiegelman and
Stanton(2000), “low levels of perceived parental monitoring were associated
with participation in several health risk behaviors, including sexual behavior,
substance / drug use, drug trafficking, school truancy and violent behaviors”.
Females perceived themselves
to be more monitored than did males. In general, the perceived parental
monitoring tended to decrease with advancing age of the youth and perceived
parental monitoring had protective effects on concurrent adolescent risk
involvement over two-year observation. The protective effect on girls’ sexual
abstinence increased significantly over time (Yang, Staifon, Li, Cottrel,
Galbraith, & Kaljee, 2007).
According to
psychoanalyst Alfred Adler, our birth order also predicted our personality to a
great extent, his theory from the early 1900s still stand in many respects,
however, it is new research that is now receiving these ideas and particularly
we are seeing the interplay of our biology and psychology, new research is
showing that birth order can predict health consequences (Varma, 2013). Alfred
Adler is known as the pioneer of the birth order theory; his belief which is
both accepted and rejected by researchers, is that the order or position of a
child’s birth in the family influences their personality. However, what is
often misunderstood is the fact that Adler did not believe it was simply the
order of birth that influenced a child’s character, but rather the child’s
environment as well as their natural instinct or interpretation of their birth
order which molded personalities (Guilbeau, 2014). There is a widespread belief
that birth order is an important determinant of personality. A distinguished
University of Georgia psychologist Alan E. Stewart wrote what is perhaps the
definitive recent work (2012) on the theory and research on birth order. He
bases his paper on 529 journal articles published over a 20 year period. Taking
his lead from the original birth order theorist, Alfred Adler (a onetime
disciple of Freud), Stewart distinguished between “actual” birth order ‘ABO’
(the numerical rank order into which you are born in your family of origin) and
“psychological” birth order, or PBO (self perceived position in the family).
Your actual birth order need not have the same impact on you as the birth order
you believe you have. Actual and psychological birth order can deviate for a
number of reasons, including illness of one child, size of family and degree of
separation between siblings.
As
explained by Stewart, using Adler’s framework, the firstborn child (or one with
the “oldest” role) would be most likely to take on a leadership position, to
like it when people stick to rules and order and to strive toward achievement
goals. The first born may be sensitive to being “dethroned” by younger sibs who
drain away the attention of parents that the first born enjoyed before they
came along.
The
youngest child may feel less capable and experienced and perhaps is a bit
pampered by parents and even older sibs. As a result, the youngest may develop
social skills that will get other people to do things for them, thus
contributing to their image as charming and popular.
Then
there’s the all-too-easy to ignore middle child, who feels probed of the prized
youngest child status and perhaps feels rejected on the positive side, the middle
child may also develop particularly good social skills in order to keep from
being ignored.
For
the only child, there’s the possible advantage of receiving all the attention
from parents, but this is balanced by the feeling of constantly being scrutinized
and controlled.
There
are also reported relationship between birth order and health. According to
Chris Weller (2015), first born are given a bevy of advantages. They receive
all of their parents’ affection and earn all the spoils. But it comes with a
price. A childhood of excess has been found to lead to several health
complications later in life. First born are more prone to diabetes, metabolic
disorders and obesity, the last of which shouldn’t come as much of a surprise.
Parents who want nothing but the best for their pride and joy tend to over feed
them. Parents also tend to helicopter over their first born when it comes to
their vaccines. A great deal of research suggests a link between firstborn and
the development of allergies, asthma and immune related disorders. Anxiety
plays a part statistically speaking; worried parents of an on child will
typically rush to get every shot and injection pumped into their kid’s veins to
prevent future illness more so than they end up doing for future children. As a
result, vaccine-related emergency room visits tend to be much higher for
firstborn than their siblings.
Weller
(2015) in his analysis noted that firstborn generally don’t engage in as much
risky behavior compared to their younger siblings, especially their youngest.
The baby of a given family is usually more likely to exhibit addictive
tendencies, such as drinking and smoking, and engage in sexual behaviors
earlier. In contrast to the strict parenting styles of the firstborn, the last
born children tend not to get as much attention, which again can either be
helpful or harmful to the development.
Before
discussing the personality traits that differ between siblings, it’s important
to keep in mind the many ways in which families operate. Health outcomes, too,
low-income families might not show the same preference of vaccinating their
eldest child more than their youngest, simply because other things take
priority, like food and paying the bills. In the sense, financial limitations
skew the average data, which it should be said isn’t a small point. (Weller,
2015). Each family operates with different constraints, but psychologists have
found several sweeping differences between kids born first and those
thereafter.
Adolescence being a
developmental transition between childhood and adulthood is characterized by
intense changes in peers, family, school, self concept and physical
development, while most young people successfully move through this transition
without serious difficulty, a variety of behavioral and mental health problems
increase during this period with significant sex differences (Francis, 2007),
while both boys and girls engage in increased levels of law-violating and other
problems behaviors during adolescence, girls commit fewer such behaviors than
boys on the other hand girls experience more depression, suicide attempts and
lower self concept than boys (Francis, 2007).
The years from 12 to 21 are
critical for the initiation and development of a range of adult behaviors, a
proportion of behaviors that put youth at risk can be seen as natural responses
to the greater freedom of choice that comes with increased physical activity
and social freedom, risk taking behaviors in particular may meet adolescents
emerging needs for autonomy, relatedness with peers, sense of personal mastery
and intimacy (Browne, Clubb, Aubercht & Jackson, 2001). Adolescence is a
time when experimentation is more likely to occur, as well as when safe and responsible
behavior patterns (e.g., safe sexual practices) are adopted. (Barowski,
lever-landis, Lovegreen & Trapl, 2003).
In this study, the three
variables of parental monitoring, birth order and gender would play independent
and significant roles in the engagement in health-risk behaviors among a sample
of adolescents.
Statement
of the Problem
Adolescence is an important
stage of life for establishing healthy behaviors, attitudes, and lifestyles
that contribute to current and future health. Health risk behavior is one
indicator of health of young people that may serve both as a measure of health
over time as well as a target for health policies and programs. It offers a window of opportunity for development of
health promoting behaviors, but also represents a period of vulnerability for
the formation of health risk behaviors. There has been a marked change of
morbidity and mortality among adolescents, who are increasingly at risk for
adverse health outcomes even death that are not biomedical in origin, this is
as a result of life-style practices and the majority of current threats to
adolescent health are the consequences of social environmental and behavioral
factors. These social morbidities include a broad spectrum of behaviors and
related outcomes such as substance use and abuse, violence, eating disorders,
teenage pregnancy and sexually transmitted diseases, to name but a few.
Further,
transmission points between childhood and adolescence are marked by widespread
developmental changes in emotional, social and cognitive development of health
related behaviors in important ways. The health risk behaviors might cluster
together in a risky lifestyle, much of the mortality and morbidity is caused by
individual behavioral patterns.
Much
research has been done to document various types of health risk behaviors, but
little research has focused on understanding the mechanisms and contextual
factors responsible for the process of behavior change.
This
study is however aimed at developing effective prevention programs based on an
understanding of the effects of parental monitoring, birth order and gender on
adolescents’ health risk behavior. Thus, the study attempted to provide answers
to the following questions:
1. Will parental monitoring affect adolescent’s health risk
behavior?
2. Does birth order contribute to adolescent’s propensity to
participate in health risk behavior?
3. Will there be gender differences in adolescents’ health
risk behavior?
PURPOSE
OF THE STUDY
Adolescence
is a time of tremendous biological, cognitive and psychosocial growth and
development, taking children on a whirlwind trajectory from early childhood to
young adulthood. It represents challenging target for research aimed at
understanding how health risk behaviors form; how they differ by birth order,
gender and the importance of parental monitoring. Thus, the objectives of the
research are:
1. To find out whether parental monitoring will
significantly affect adolescent’s health risk behavior.
2. To find out whether birth order will significantly
contribute to adolescent’s propensity to participate in health risk behavior.
3. To examine whether there is significant gender
differences in adolescents’ health risk behavior.

BEHAVIOUR THEORY
BIOLOGICAL-MATURATIONAL THEORY
Biological-maturational theory is of the view
that certain aspects of human behavior are related to the physiological factors
such as hormone levels, inherited traits, or neurological disorders. Biological
views dominated the beliefs and research on adolescence during the early 1900s.
One of the most important scholars of adolescence development Hall pioneered
and popularized biological views of adolescence at the turn of the century.
Hall’s theory is probably the earliest formal theory of adolescence and as such
he is dubbed the father of a ‘scientific study of adolescence’ (Hall, 1904).
According
to Hall (1904), adolescence is a distinct and tumultuous time of life when our
behavior is primarily determined by the way our species is genetically
programmed. Hall believed that adolescents are genetically destined to be
especially prone to rapid, rebellions and sometimes life threatening changes in
behavior. Therefore, Hall promoted the biological viewpoint that adolescent is
universally a difficult, troublesome period of life.
From
the biological view point many of the changes in a person’s behavior during
adolescence is related to the physiological changes that occur during the
teenage years; likewise, many of the differences in their physiological
make-up. Researchers have found associations between certain aspects of teenage
behavior and physiological factors such as disorders in the neurological
system, hormone imbalances and inherited disturbances. For example, male
delinquents who continue to engage in criminal activities beyond adolescence
have lower levels of adrenal secretions than male delinquents who don’t become
criminals as adults. Much research supports the theory that certain aspects of
an adolescent’s behavior and mental health are influenced by biological
factors. Most researchers who study adolescence from biological view point
today, however, consider themselves advocates of biosocial theories- That is,
biological and environmental factors work together to account for our behavior
during adolescence (King, 2004).
BEHAVIORAL AND SOCIAL LEARNING THEORY
Unlike
strictly biological theories, behavioral and social learning theories are based
on the promise that most of how we behave and who we become during and after
adolescence is determined by environmental influences. Although, behavioral and
social learning theorists do not deny that biological factors influence our
behavior, they emphasize the impact that our experiences have on our
development. Among the most important environmental factors are the kinds of
behaviors and ways of thinking that are reinforced or punished at home, at
school, by peers and the society. The idea that environmental factors play a
large role in determining how people behave during adolescence initially gained
wider recognition through the research of anthropologists Ruth Benedict and
Margaret Mead. Both women pointed out that adolescents in other societies
behave differently than American teenagers because each group is socialized
differently. In opposition to Hall’s still popular views, Mead and Benedict
were showing that adolescence is not a particularly stressful or rebellious
period in every society. How children are socialized has an impact on how they
think and behave when they become adolescents (Muss, 1996)
Research
emerging from sociology at the time also back up these anthropological
findings, Sociologists were finding that teenagers behaved in different ways
according to the kind of families they come from. In conjunction with the early
sociological and anthropological studies, support was growing among
psychologists for a theory being developed by. B.F. Skinner known as behavioral
or Skinnerian psychology. According to Skinner and other behavioral
psychologists, most of an individual’s behavior and attitudes are a result of
the ways he or she has been reinforced or punished since birth.
PSYCHOANALYTIC THEORY
Psychoanalytic
theorists like the behavioral and social learning theorists believe that our
teenage behavior and development are influences from environmental factors –
mainly by the kinds of experiences we have during the first few years of our
lives in our families. Unlike other theorists, however, psychoanalytic
theorists put the most emphasis on our early childhood experiences (Freud,
1958). Above all, how our mothers relate to us in the first few years of our
lives supposedly shapes our ways of thinking and relating to people from there
on. For example teenagers who continually have trouble getting along or
becoming intimate with people and becoming self reliant have often had
unloving, ambivalent, or overly involved, relationships with their mothers
during early childhood. These teenagers have apparently developed maladaptive
ways of reasoning and behaving around people based on problems in their
relationships with their mothers as infants and pre-schoolers.
Psychoanalytic
theorist also see our development progressing in distinct stages during which
certain psychological and sexual issues need to be resolved if we are to become
well adolescents and adults. Because the founder of psychoanalytic theories was
Sigmund Freud, they are commonly referred to as Freudian theory.
Contemporary
Psychoanalytic theorists such as Peter Blos and Erik Erikson have modified
Freud’s original theories. According to these more recent theories, the
experiences we have after early childhood continue to influence our development
in particular period for shaping and reshaping certain aspects of ourselves.
Indeed, adolescence is a crucial time for separating on “individuating” enough
from families to build close relationships with peers and to function in the
adult world. Like Freud, however, newer psychoanalytic theorists still consider
our childhood experiences with our parents and the dynamics within our families
to have a significant impact on how we think and behave as teenagers (Blos,
1979; Erikson, 1956).
COGNITIVE STAGE THEORY
Like the Freudians, cognitive stage theorists believe that
adolescent behavior is related to stages of development unlike the Freudians,
however, the cognitive stage theorists see stages of human development as
mental, not as psychological or sexual. Throughout childhood, we supposedly
move into more advanced mental stages that enable us reason, to solve problems
and to interact with people in more mature ways. The process of maturing that
we observe in most adolescents, therefore is seen as evidence of their having
finally arrived at the higher cognitive level – a stage referred to as “formal
operational thinking” on the other hand, those adolescents who think and behave
in extremely immature ways are seen as being stuck, so to speak, in the
childhood stage of reasoning referred to as “concrete operational thinking”.
Thus, adolescence is considered a distinct, unique phase of life because young
people are advancing to a new cognitive stage that enables them to behave more
maturely (Oswalt, n.d). These adolescent changes however are not considered to
result mainly from environmental influences, family dynamics or early childhood
experiences. Because Jean Piaget is considered the founder of cognitive stage
theories, they are often referred to as Piagetian theories. Piaget began to look at the period of
adolescent development later in his career with the publication of The Growth of Logical Thinking from Childhood to Adolescence (with B. Inhelder, 1958). Probably some of
Piaget's notions about cognition came from his work and experiences as an
assistant to Alfred Binet in Paris, while Binet was developing his intelligence
test. Piaget became fascinated with the thought processes children revealed in
attempting to solve test problems.(King, 2004)
ECOLOGICAL SYSTEMS THEORY
Brontenbrenner
is one of the most well known psychologists in the field of developmental
psychology. Bronfenbrenner’s ecological systems theory is arguably his most
acknowledged work.
Bronfenbrenner’s (1979) defines complex
“layers” of environment, each having an effect on a child’s development. This
theory has recently been renamed “bioecological systems theory” to emphasize
that a child’s own biology is a primary environment fueling her development.
Changes or conflict in any one layer with ripple throughout other layers. To
study a child’s and her immediate environment; but also at the interaction of
the layer environment as well.
Bronfenbrenner’s
structure of environment include: the microsystem, the mesosystem, the exosystem
and the macrosystem.
The
Microsystem: This is the layer closest to the child and contains the structures
with which the child has direct contact. The microsystem encompasses the
relationships and interactions a child has with her immediate surroundings
(Berk, 2000). Structures in the micro system include family, school, neighborhood,
or childcare environments. At this level relationships have impact in two
directions. For example, a child’s parents may affect his behavior; however the
child’s parents may affect his behavior; however the child also affects the
behavior of the parent. Bronfenbrenner’s
calls these biodirectional influences.
The
mesosystem: This layer provides the
connection between the structures of the child’s microsystem (Berk, 2000)
Examples: the connection between the child’s teacher and his parent etc.
The Exosystem: This layer defines the
larger social system in which the child does not function directly. The
structure in this layer impacts on the child’s development by interacting with
some structure in her micro system. (Berk, 2000). Parent workplace schedules or
community-based family resources are examples.
Finally, the macrosystem: This layer
may be considered the outermost layer in the child’s environment. This layer is
comprised of cultural values, customs and laws (Berk 2000).
The chronosystem encompasses the
dimension of time as it relates to a
child’s environments. Elements within this can be either external, such as the
timing of a parents death, or internal such as physiological changes that occur
with the aging of a child. As children get older they may react differently to
environmental changes and may be more able to determine more how that change
will influence them. Bronfenbrenner’s
sees the instability and unpredictability of family life we have left our
economy create destructive force to a child’s development (Addison, 1992)
TRANSITIONAL TEENS THEORY
Although this theory focuses largely
on the problems associated with adolescent impaired driving, transitional teens
theory (Voas & Keller- Baker, 2008) also provides a general framework for
understanding trajectories into adolescent substance abuse and criminal
conduct.
Transitional Teens Theory (TTT)
defines four key elements that significantly affect behavior; namely; the
developmental dynamics and status of the adolescent; parental influence;
social, environmental and community influences; and peer influences. The later
three are considered to be external influences. All four can operate as either
risk or protective factors that influence adolescent behaviors, development and
decisions.
During this period, parental influence
and supervision decrease, and time independent of that influence increases. The
automobile enhances this independence from parents. The protective components
of the community and environment substitute somewhat for the decrease in
parental supervision.
It is inevitable that the teen will
experience more and more independence from adult influences during this period.
Most relevant during this period is the period group and, more specifically,
what Voas and Kelley-Baker (2008) call small affinity groups, mainly defined by
the number of teens who can fit into an automobile. This small group, because
of the car, can travel away from the home environments supervisory regulations
to locations where they perceive themselves to have more control over their own
behavior.
However,
this sense of self control may be a distortion since they may find themselves
in environments with which they are less familiar and in which they have less
control. The risk increases when small the small affinity or intimate group has
deviant behavior norms.
ACQUIRED PREPAREDNESS MODEL
G.T. Smith and Anderson (2001) present
a risk model for understanding the development of adolescent problem drinking
based on personality and learning factors. They combine personality factors
based on traits that are predictive of alcohol problems and that have genetic
loadings with learning factors that are more environmentally determined. The
combination of these two risk factors creates what they call an acquired
preparedness for the development of alcohol abuse and associated problem
behaviors.
Infer woven with this model is the
curial stage of development in which adolescents are faced with, and engage in,
the task of differentiating themselves from parents and family and broadening
their rage of experiences beyond family and parental protection and control.
They must confront the challenges of controlling urges and managing their interpersonal
and social experiences. These challenges have potentially positive or negative
outcomes. One area of challenge is drinking alcohol, which some researchers
conclude is part of this development process. (see G.T. Smith and Anderson,
2001).
In
summary, acquired preparedness model (APM) holds that adolescents who show the
disinhibited personality trait (disinhibition impulsivity) and behavioral under
control are ready to learn the positive reinforcing aspects of risk-taking
behavior more than they are ready to learn the punishing aspects of risk-taking
behavior. When this readiness (dishibition) is combined with alcohol expectancy
learning or other drug expectancy learning there is a bias toward alcohol and
other drug expectancies over negative expected outcomes. Alcohol expectancies,
enhanced by disinhibition can predict the outset of alcohol use and related
problems. This model is applicable to some adolescent as they navigate through
the various developmental tasks and stages of adolescence, particularly those
who tend to fit the disinhibited personality pattern. Smith and Anderson (2001)
made it clear that the APM can help identify “one sub-group of high-risk
adolescents” and not necessarily applicable to all adolescents.
THEORY OF PLANNED BEHAVIOR
The
theory of planned behavior (TPB) was developed by Ajzen and is seen as an
extension of the theory of reasoned action (Fishbein & Ajzen, 1975). The
theory of reasoned action holds that the intention (motivation) to perform
certain behavior is dependent on whether individuals evaluate the behavior as
positive (attitude) and if they judge others as wanting them to perform the
behavior (subjective norm). TPB builds on this theory and holds that all
behavior is not executed under purposeful control and that behavior lie on a
continuum from total control to complete lack of control. TPB is based on the
correction between attitudes and behaviors.
Behavior is guided by three kinds of
beliefs and cognitive outcomes; viz: behavioral beliefs, normative beliefs and
control beliefs. Behavioral beliefs are the expected or likely outcome of the
behavior that produces a favorable or unfavorable attitude toward the behavior
(outcome).
Normative
beliefs are what others expect and the desire of the individual to follow those
expectations. These beliefs result in the degree of social pressure to comply
or subjective norm; the adolescent thinks others (eg. Peers) want him or her to
perform the behavior.
Control beliefs are the ease or difficulty
of performing the behavior resulting in the degree of perceived behavioral
control (outcome).
SOCIAL NORMS THEORY
Social norms theory (SNT) describes
situations in which individuals incorrectly perceive the attitudes and / or
behaviors of peers and other community members to be different from their own
when in fact they are not. This phenomenon has been called “pluralistic
ignorance” (Miller & Mcfarland, 1991; Toch & Klotas, 198). These
misperceptions occur in relation to problem or risk behaviors (which are
usually overestimated) and in relation to healthy or protective behaviors
(which are usually underestimated). The social norms approach had its start
with research in the 1980s by Perkins and Berkowitz based on a research
conducted at Hobart and William Smith Colleges in the 1980’s (Berkowitz &
Perkins, 1987; Perkins & Berkowitz, 1986). The approaches use a variety of
methodologies to provide normative feedback as a way of correcting
misperceptions that influence behavior.
The first social norms intervention
was initiated in 1989 by Michael Haines at Northen Illinios University (Haines,
1996; Haines & Barker, 2003; Haines & Spear, 1996). Haines expanded on
the theory by applying standard social marketing techniques to present the
actual healthy norms for drinking to students through specially designed media.
SNT holds that subjective norms or the perceived expectations of other or of
peer groups who approve or disapprove of a particular behavior, along with
attitudes toward the behavior are determinants of that behavior. SNT posits
that people are highly influenced by what they think their peers are doing or
thinking and then confirm to what they believe is the norms that come from
incorrect assessment of what others do will influence social behavior.
Social norms theory can be used to
develop interventions that focus on three levels of prevention specified as
universal, selective, and indicated (Berkowitz, 1997). Universal prevention is
directed at all members of a population without identifying those at risk of
abuse. Selective prevention is directed at members of a group that is at risk
for a behavior. Indicated prevention is directed at particular individual who
already display signs of the problem. Interventions at all levels of prevention
can be combined and intersected to create a comprehensive program that is
theoretically based and has mutually reinforcing program elements (Berkowitz,
2003).
PROBLEM BEHAVIOR THEORY
Problem-behavior
theory is a systematic, multivariate social psychological conceptual framework
derived initially from the basic concepts of value and expectation in Rotter’s
(1954, 1982) social learning theory and from Merton’s (1957) concept of anomie.
The fundamental premise of the theory, all behavior is the result of
person-environment interaction, reflects a “field theory” perspective in social
science (Lewin, 1951). The earliest formulation of what later came to be known
as problem behavior theory was developed in the early 1960’s to guide a
comprehensive study of alcohol abuse and other problem behaviors in a small,
tri-ethnic community in south western Colorado (Jessor, Graves, Hanson, and
Jessor, 1968). In the following three decades, problem-behavior theory has been
revised and extended during the course of studies by Richard Jessor and his
colleagues. It was first adapted for the follow-up study of the earlier cohorts
of adolescents and youth to encompass the developmental stage of young
adulthood (Jessor, Donovan, & Costa, 1991).
Problem
behavior theory (PBT; Jessor, 1987a, 1991, 1998; Jessor & Jessor, 1977) is
a broad-brand and widely used theory to explain dysfunction and maladaptation
in adolescence. The fundamental premise of PBT, developed initially from
Merton’s (1957) concept of anomic and Rotter’s (1954) social learning theory,
is that all behavior emerges out of the structure and interaction of three
systems. The behavior system, the personality system, the perceived
environment. Each system is composed of variables that serve either as
instigations for engaging in problem behavior or controls against involvement
in problem behavior. It is the balance between instigations and controls that
determines the degree of proneness for problem behavior within each system. The
overall level of proneness for problem behavior, across all three systems,
reflects the degree of psychosocial conventionality characterizing each
adolescent.
The concepts that constitute the
perceived environment system include social controls models, and support.
Perceived environment variables are distinguished on the basis of the
directness or conceptual closeness of their relations to problem behavior. Proximal
variables (for example, peer models for alcohol use) directly implicate a
particular behavior, where as distal variables (for example, parental support)
are more remote in the causal chain and therefore require theoretical linkage
to behavior. Problem behavior proness in the perceived environment system
includes low parental disapproval of problem behavior high peer approval of
problem behavior, high peer model for problem behavior, low parental controls
and support, low peer controls, low compatibility between parent and peer
expectations and low parent (relative to peer) influence.
The concepts that constitute the
personality system include a patterned and interrelated set of relatively
enduring, socio cognitive variables values, expectations, beliefs, attitudes,
and orientations toward self and society that reflect social learning and
developmental experience. Problem behavior proneness in the personality system
includes lower value on academic achievement, higher value on independence,
greater social criticism, higher alienation, lower self-esteem, greater
attitudinal tolerance of deviance, and lower religiosity.
The concepts that constitute the
behavior system include both problem behaviors and conventional behaviors.
Problem behaviors include alcohol use, problem drinking, cigarette smoking,
marijuana use, other illicit drug use, general deviant behavior delinquent
behaviors and other norm volatile acts), risky driving and precocious sexual
intercourse. Involvement in any one problem behavior increases the likelihood
of involvement in other problem behaviors due to their linkages in the social
ecology of youth.
In summary, within each explanatory
system, it is the balance of investigations and controls that determines
psychosocial proness for involvement in problem behavior; and it is the balance
of instigations and control across the three systems that determine the
adolescent’s overall level of problem behavior proneness or psychosocial
unconventionality.
REVIEW OF EMPIRICAL LITERATURE
ADOLESCENTS AND HEALTH RISK BEHAVIOR
Adolescence is a period during which
youth experience physical, neurological, and cognitive transformations, as well
as shifts in the nature of relationships by developing new social ties and
roles across social domains (Moretti, 2004; Weisz and Hawley, 2002). As
consequences of such dynamic transformations, youth may become easily
vulnerable to multiple forms of risks related to poor health and health risk
behavior during this period.
The Center for Disease Control and
Prevention ( CDCP, 2010) on its 2009 national Youth Surveillance survey United
States reported that a startling proportion of youth (9th to 12th
graders) in the U.S have experienced poor health and health risk behaviors. For
example, among youth nationwide, 26.1% experienced depressive symptoms (felt
sad or hopeless almost every day for two or more weeks in a row to the extent
that it hindered their daily activities during the past 12 months) 31.5% were
involved in physical aggression (involved in a physical fight one or more times
in the past 12 months), 19.5% smoked cigarettes on at least 1 day during the
past 30 days, 41.8% consumed alcohol (had at least one drink of alcohol 1 day
in the past 30 days) 24.2% experienced binge drinking (had five or more drinks
within a couple of hours on at least one day during the past 30 days), and
38.9% of the sexually active youth did not use conceptive during their most
recent sexual intercourse.
Research contents that various health
risk behaviors that are developed at an early stage may often result in
elevated risks of experiencing severe levels of morbidity or mortality in
adulthood (CDCP, 2010; Kessler, Berglund, Demler, Jin, Merikangas, & Walters,
2005; Merin-Kangas, He, Burstein, Swanson, Avenevoli, Cui, & Swendsen
2010). Estimates for the age-of-onset distributions of the Diagnostic and
Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) disorders from a
nationally representative U.S. study of adults support this finding, as the
time of diagnosis for clinical levels of disorders for post survey respondents
was around early adulthood (Kessler et al., 2005). More specifically, the 25th
and 75th percentile range of the age-of-onset distributions was
18-27 years of age for substance use disorders (eg. Alcohol abuse and
dependence) and 18-43 years for mood disorders (e.g, major depressive
disorder). These estimates suggest that if non-severe levels of behavioral
health conditions during adolescence are unattended, those mental health
conditions and health risk activities may result in severe consequences later
in life.
The adolescence-adulthood temporal
continuum of behavioral health conditions that is, observed in empirical health
research is in accordance with the life course perspective (Elder, 1998). In
detail, the theoretical view asserts that risk behaviors that are developed
earlier in life, but are left to proliferate, may evolve into even greater
medium- and long term health-related consequences through the accumulation of
disadvantages. Consistent with the existing empirical findings, proponents of
this theoretical perspective will claim that health risk behaviors in adulthood
are strongly contingent upon their disadvantaged life experiences in the past
including adolescence. However consistent with the findings of U.S youth (Center
for Disease Control and Prevention [CDCP], 2010), existing literature
concerning south Korean youth has suggested that adolescence is the period
during which a large fraction of youth engage in various types of health behaviors
for the first time (MOGEF, 2010; Rhee, Yun, & Khang, 2007).
In particular; underage drinking and
smoking is highly prevalent in Korea and has been considered a severe public
health risk since 1990s (Hong, Lee, Grogan-Kaylor, & Huang, 2011). In 1999,
in response to rising public demand, the juvenile Act was introduced. The law prohibits
commercial businesses and individuals from offering services and products that
may inflict harm towards the wellbeing of youth under the age of 19. Despite
legislative efforts, a study conducted in 2010 revealed that a large proportion
of middle school and high school students reported consuming alcohol (51.9%)
and smoking (18.7%) in their lifetime (MOGEF, 2010).
The foundation for preventing youth
violence (FPYV, 2009) reported that in addition to substance use behaviors,
aggression, particularly in the form of verbal and physical harassment within
the school environment has also been of national concern in Korea. Despite
legislative efforts to prevent the use of aggression and protect vulnerable
victims on school grounds, national reports have shown that 12.4% of youth
reported to have exerted aggression toward other students at school in the past
year.
PARENTAL MONITORING AND ADOLESCENTS’
HEALTH-RISK BEHAVIOR
Research has amply documented that the
greater the communication between parent and adolescent and the greater the
parent knowledge of the adolescents’ whereabouts (i.e; parental monitoring),
the lower the likelihood that the adolescent will engage in health risk
behavior (Chilcoat & Anthony; 1996; Li, Stanton & Feigelman, 2000; Li,
Feigelman and Stanton, 2000, Steinberg, Fletcher & Darling, 1994; Stattin
& Kerr; 2000; Dishion & Roeber 1985; Pittman &
Cahse-Rangdale,2001).
Barowski et al (2003) revealed that
adolescents who report that their parents allow them to negotiate unsupervised
time with peers were more likely to be sexually active and to use substance
(alcohol and marijuana than the adolescents who do not, even when comparing
adolescents who are similar in parental monitoring.
However, these adolescents are also
more likely to engage in sex-related protective measures such as consistent
condom use, carrying protection, or refusing sex when protection is not
available. Interestingly, these results were very similar in magnitude and
direction for males and females alike. Although parents of female adolescents
were less likely to negotiate unsupervised time than parents of male
adolescents, when they do the effects appear to be same.
A significant proportion (40% to 60%)
of these adolescents also reported being allowed to stay past curfew hour if
they call, have friends over when their parents aren’t home and have a place in
their home where they can hang out unmonitored. However, even when the sample
is restricted to this highly monitored group, the higher the level of
negotiated unsupervised time, the increased likelihood of sexual activity,
substance use (alcohol and marijuana), and responsible sexual behaviors
(consistent condom use, carrying protection). Thus, although the degree to
which parents use negotiated unsupervised time is much less than general
monitoring practices, this parenting practice does not appear to be rare, nor
found only among adolescents who are poorly monitored. These findings suggested
that when parents allow negotiation to occur adolescents may be permitted more
opportunity for experimentation to occur. (Barowski, et al. 2003).
Diclemente, Wingood, Crosby, Sionean,
Cobb, Harrington, Davies, Hook & Oh (2001) examined parental monitoring
association with adolescents’ risk behaviors. Recruiters screened a sample of
1130 teens residing in low-income neighborhoods. Adolescents were eligible if they
were black females between the ages of 14 and 18 years, sexually active in the
previous 6 months, and provided written informed consent. Teens (n=609) were
eligible and 522 (85.7%) participated, variables in 6 domains were assessed,
including sexually transmitted diseases, sexual behaviors marijuana use,
alcohol use, anti-social behavior and violence, the results in logistic
regression analyses, controlling for observed covariates indicate that
adolescents perceiving less parental monitoring were more likely to test
positive for a sexually transmitted disease /odds ratio [OR] : 1.7), report not
using a condom at last sexual intercourse (OR: 1.7) have multiple sex partners
in the past 6 months (OR: 2.0), have risky sex partner in the past 30 days (OR:3.0),
and not use any contraception during the last sexual intercourse episode (OR:
1.9). furthermore, adolescents perceiving less parental monitoring were more
likely to have a history of marijuana use and use marijuana more often in the
past 30 days (OR: 2.3 and OR:2.5, respectively); have a history of arrest
(OR:2.1) and there was a trend toward having engaged in fights in the past 6
months (OR: 1.4). These findings demonstrate a consistent pattern of health
risk behaviors and adverse biological outcomes associated with less parental
monitoring.
Biddlecom, Awusabo-Asare and Bankole
(2009) studied four African countries of Burkina Faso, Ghana, Malawi and Uganda
drawing a nationally representative survey of 12-19 years olds. Bivariate
analysis compared gender differences for two outcomes among unmarried 15-19
years olds-having had sexual intercourse in the last 12 months and, among those
who had in this period, contraceptive use at last sex. Multivariate logistic
regression indentified associations between these outcomes and co-residence
with parents or parent figures, parental monitoring and parent-child communication.
The results indicate that adolescents reported moderate to high levels of
parental monitoring and low levels of parent-child communication on sexual
matters. In all countries, adolescent males who reported low monitoring were at
elevated risk of having had sex in the last year (odd ratios: 2.4-5.4) as were
their female counterparts in three of the countries (6.9-7.7). Parental
monitoring was not associated with contraceptive use at last sex.
BIRTH ORDER AND ADOLESCENTS’ HEALTH-RISK
BEHAVIOR
Argys, Rees, Averett & Witonchart
(2006) examined the relationship between birth order and adolescents’ health
risk behaviours using data from National Longitudinal Survey of Youth- 1997
cohort (NLSY97). The NLSY97 was launched to enable researchers to define the
transition that adolescents make from school to the labor market and into
adulthood. In addition to including schooling and labor market information, the
NLSY97 contains detailed questions on family background, personal
characteristics, and a variety of behaviours that can be considered risky.
Respondents to the NSLY97 have been
surveyed on an annual basis beginning in 1997. The initial wave of the NLSY97
consisted of a representative sample of the U.S population aged 12-16 years on
December 31, 1996 (n=6, 748), coupled with a supplemental over sample of black
and Hispanic adolescents (n=2, 236). The study uses data from respondents
between the ages of 12 and 17 who were interviewed at least once during the
first three waves of the NSLY97. Respondents could contribute up to 3
observations to the analysis. Using ACASI (Audio Computer Assisted
Self-Interview) technology outcome variables by gender and the presence of an
older sibling, information on tobacco, marijuana, and alcohol consumption;
sexual activity; birth control and criminal/ delinquent behaviors was
collected. The result indicates that children with older siblings are, on
average, more likely to have used tobacco, alcohol and marijuana than their
firstborn counterparts controlling for family size, age and the other factors
in the model. For instance, females with older siblings are 8 percentage points
more likely to have smoked cigarettes than are their first born counterparts.
A positive relationship between older
siblings and substance use is not consistent with the arguments that
experienced parents provide better guidance for their younger children or the
notion that older siblings serve as positive role models. This result is more
in keeping with the argument that adolescents with older siblings are
“prematurely” exposed to behaviors initiated by their older siblings at later
ages, although it could reflect differences in parental monitoring and
supervision or even a beneficial effect of having younger siblings.
On the estimates of the relationship
between birth order and adolescent sexual behavior, two dependent variables are
considered: the first is an indicator of adolescents ever having had
intercourse, whereas the second is an indicator of whether they used
contraception at first intercourse and it applies only to the subsample of
respondents who indicated that they had sexual intercourse. For both males and
females there are substantial (7.4 and 4.0 percentage points, respectively)
increases associated with the presence of an older sibling in the probability
of having had intercourse. This result might indicate that middle borns are at
risk of experiencing unwanted pregnancies and contracting sexually transmitted
diseases. Using a subsample of respondents who had sexual intercourse,
estimates of the effect of birth order on the probability that contraception
was used at first intercourse. They provide little evidence that birth order is
related to this probability. The report also suggest that younger brothers and
sisters are more likely to be sexually active than their first born
counterparts and that older sibling decreases the probability that sexually
active females used birth control in the past year.
It is not surprising that birth order
seems to have a long-lasting influence on smoking as compared to that on
drinking or marijuana use. Cigarettes are highly addictive and as Gruber and
Zinman (2001) have shown, most adult smokers begin their habit as adolescents.
The relationship between having an older sibling and smoking as an adult
suggests that birth order should be related to long-run health outcomes.
GENDER AND ADOLESCENTS’ HEALTH-RISK
BEHAVIORS
Gender differences in the distribution
of youth risk behaviors reported by Salvadoran students. Male students were
significantly more likely than female students to report all aggression-related
behaviors as well as two of the four victimization behaviors having been
threatened or hurt with a weapon and feeling too unsafe to go to school. This
gender difference for engagement in violence related behavior is reflected in
the larger Salvadoran population, where 70-80 of homicides occur among males,
with more than half occurring among males aged 15-30 years (Cruz, 1997). The
20% of male adolescents who reported carrying a weapon in the past 30 days
along with the over 40% who reported participating in a physical fight in the
past year may be causes for concern given that EI Salvador has been reported to
have the highest homicide rate among young people in the Americas (Eberwine,
2003). Females (20%) reported that they had been forced to have sexual
intercourse, and female students were almost four times likely to report having
been forced to have sexual intercourse as males.
Heise, Ellsberg, & Gottmoeller
(2002) reported that between one-third and two-thirds of known sexual assault
victims are age 15 or younger based on justice system statistics and rape
crisis centers in eight countries, which included the U.S and four Latin
American countries. In Nicaragua, one study found that 26% of women between the
ages of 25 and 44 reported that they had experienced sexual abuse before the
age of 19, and 15% reported having been victims of attempted or completed rape,
a rate twice that of men (Olsson, Ellsberg, Berglund, Herrera, Zelaya &
Pena, 2000).
Female students were also more likely
than male students to report feelings of sadness and hopelessness, suicidal
ideation and suicidal attempt. A finding that follows similar gender patterns
exhibited in the U.S adolescent population (Kann, Kinchen, Williams, Ross, Lory
& Hill 2000; Grunbaum, Kann, Kinchen, Ross, Hawkins & Lowry, 2004); and
that coincides with the significantly higher rates of depression found for
female adolescents in Canada, Great Britain and the Unites States (Wade,
Cairney, Pevalin, 2002). Gender differences in suicidal ideation and suicide
attempt identified in these students also mirror the broader epidemiologic
profile of El Salvador (Organization Panamamerica de la salud [OPS], 1998),
Guatemala (Berganza and Aguilar, 1992) and Nicaragua (Caldera, Herreram
Renberg, Kullgren, 2004) in terms of the higher suicide rates reported for
adolescent females.
Research has found similar lifetime
tobacco prevalence use and marijuana
use, as reported for Salvadoran adolescents (mean age = 16 years, n=1,628) as
revealed by Dormitzer, Gonzalez, Penna, Bejarano, Obando, Sauchez (2004) the
relatively high percentage of students reporting cigarette use along with the
lack of statistically significant difference for binge drinking between male
and female students suggests that these substances may be the more socially
accepted among both genders than marijuana use. The higher prevalence of
tobacco and alcohol use as compared to other drugs mirrors similar findings
from a study conducted with youth in the early 1990s in San Salvador (OPS,
1998) as well as later findings from Dormitzer et al (2004).
Several interesting gender differences
in sexual behaviors are worth noting, with perhaps the most striking being the
large difference in reporting of sexual experience. Just under half of the male
study participants reported having had sexual intercourse as compared with
under 8% of females, and males were significantly more likely to report having
had sex at or before age of 13 years one explanation for these differences in
sexual behavior is a reporting bias in which males may exaggerate and females
under represent their sexual experiences. Gender differences in prevalence of
sexual intercourse may also be due to a possible cultural acceptance for young
males to engage in sexual intercourse at an early age, which is supported by
similar findings of sexual experience in male youth in Nicaragua (Zelaya,
Marin, Garcia, Berglund, Liljestrand, & Persson, 1997; Rani, Figueroa &
Ainsle, 2003). Lastly, with fairly equal proportions of sexually experienced
male and female students reporting no condom use, this finding is of particular
concern when considering that El Salvador has one of the highest teenage
pregnancy rates in latin America and the Caribbean (Kasischke & Morales-Carbonell,
1998); ranking fourth out of the eight countries in the central American region
according to the state of world population (1999) with the population ages
15-24 years accounting for 26.7% of the HIV/AIDS cases in EL Salvador in 2000
(PAHO, 2002); the need for education that promotes safe sexual practices among
adolescents is further emphasized. Recognizing that sexual abstinence and the
possible use of contraceptive methods may account for the lack of pregnancy
experience reported by females in the study.
SUMMARY OF LITERATURE REVIEW
Theories
of adolescence which explain the stages of development, how the adolescents see and evaluate themselves
were reviewed in this study. Such theories include; Biological-maturational
theory, Behavioral and Social Learning theory, Psychoanalytic theory, Cognitive
Stage theory and Ecological Systems theory. More also, theories of adolescents’
health risk behaviors which try to explain its relationship with environment
were also reviewed. Theories here include; Transitional Teens Theory, Acquired
Preparedness Model, Theory of Planned Behavior, Social Norms Theory, and Problem
Behavior Theory.
Relevant
empirical studies reviewed in this study were categorized into four sections:
Adolescents and health risk behavior, Parental Monitoring and Adolescents’
Health risk behavior, and Gender and Adolescents’ Health risk behavior. They
investigated the influence of various variables on adolescents’ health risk
behavior in which some established a positive relationship and some did not.
Thus, the need for the researcher to throw more light on these related constructs
embarked on the research.
RESEARCH HYPOTHESES
1. There will be no
statistically significant differences between high parental monitoring and low parental monitoring on
adolescents’ health risk behavior.
2. There will be no
statistically significant birth order differences on adolescents’ health
risk behavior.
3. There will be no
statistically significant gender differences on
adolescents’ health risk
behavior.
