Do men and women differ in behavioral problems?
According to Academic Dictionaries and
Encyclopedias, behavioral problems refer to the symptomatic expression of
emotional or interpersonal maladjustment, particularly in children. They are
characterized by developmental deficits that produce impairments of personal,
social, academic, or occupational functioning. Behavior Disorders have been on
the rise among children according to the Centers for Disease Control and
Prevention (CDC; 2013). A behavior disorder is the observable responses, actions, or activities
of someone; it is a general concept referring to any type of behavioral
abnormality that is functional in origin. Two types of behavior include
adaptive behavior and contingent behavior. Adaptive behavior is behavior that
fosters effective or successful individual interaction with the environment.
Contingent behavior is an action dependent upon a specific stimulus. Behavior
Disorders can include attention deficit hyperactivity disorder (ADHD), Conduct
Disorder (CD), Oppositional Defiant Disorder (ODD), Emotional Behavioral
Disorder (EBD), and Mental Health Illnesses[1].Behavioural
problems may become so severe that they threaten normal relationships between
the child and others, or interfere with the child's emotional, social and
intellectual development[2].
A behavior problem also has a cause or a number of causes. The way the child
behaves is clear enough to suggest that he or she has a problem. This outward
manifestation of the child's problem through typical behavior may not indicate
the true cause(s) of his or her problem[3].
Knowing that inherited DNA differences are extremely important in shaping all
aspects of our identity, including our weight, intelligence and even likelihood
of having behavioral problems. While we can explain some factors that can cause behavior problems,
there are still many questions to be answered, particularly about individual
differences. Such as: Do men and women differ in their behavioral problems?
In fact, our understanding of behavioral problems
is still quite limited. This gap seems to deserve to be clarified by evidence
from studies of genetic and environmental influences that take into account the
differences between people who are inherited from DNA.
The
understanding of individual differences in behavioral problems is the subject
of lively debates where positions sometimes clash radically. Three (3) mains approaches
have been identified: biological, environmental and genetic.
The biological viewpoint, on the other hand,
would involve looking at the biological roots that lie behind aggressive
behaviors and tends to stress the importance of nature[4].
This approach believes behavior problems to be as a consequence of
our genetics and physiology. Thus, it examines
the relationship
between mind and body, neural mechanisms,
and the influence of heredity on behavior. This perspective used three ways to
study the behavior problems: 1) Brain physiology; 2) Comparative method; 3) Investigation of inheritance [5].Someone
who takes the biological perspective might consider how certain types of brain
injury might lead to aggressive actions. The studies of cortical ablation and subcortical lesions
in animals and clinical studies of brain-damaged children and adults have shown
a correlation between cerebral lesions with the symptoms of hyperkinesia,
distractibility, and inattention[6].
In fact, children whose families have
suffered from Behavioural or learning disorders, anxiety, depression or bipolar
psychosis may be at greater risk of developing conduct disorders[7].
Furthermore, certain genetic factors
that can contribute to such displays of behavior problem[8].
The possible roles of heredity, teratogens, family, peers, parent-child
relationship and child temperament have been documented in several studies (Wolfe,
Crooks, Lee, McIntyre-Smith, & Jaffe, 2003). Therefore, the assumption that
boys are more apt to have behavioral problems than women find its source in
this approach.
However, the genetic theory does not take
into account neurological factors. Hence its limitations and the fact that it
has been supplanted by neurological theory which instead emphasizes the effect
of hormonal activities in the brain. According to the proponents of the
neurological[9] current,
behavioral problems are linked to a disturbance of the limbic system (seat of
the emotions). There
is growing evidence indicating childhood traumatic brain injury (TBI) is the
most common cause of disability and death in young people (Kolk, Ennok,
Lougesaar, Kaldoja, & Talvik, 2011). In addition, dopaminergic dysfunctions of the
mesocortical, mesolimbic and nigrostriatal pathways[10] .Frank Elliot, an American
psychiatrist, one of the most convinced proponents of this school of thought,
believes that violence is caused by an uncontrolled electric shock in the
temporal lobe. It could have its origins in early trauma to the brain, such as
temporary asphyxiation during childbirth or early childhood. He also believes
that metabolic disorders like hypoglycemia can also trigger behavioral problems.
In several studies, alcohol, tobacco and drug use during pregnancy has been
linked to the occurrence of behavior problem, both in infancy, school age and
adolescence. A recent review of the literature reports the results of research
that investigated the link between teratogens and ADHD symptoms in children.
The strongest associations are those involving prenatal exposure to tobacco and
alcohol and postnatal lead exposure (Yolton et al., 2014). In addition,
significant associations are found to a lesser extent for exposure to cocaine,
heroin and organochlorine pesticides. If a traumatic brain injury is left untreated, issues may
persist into childhood, adolescence, and adulthood predisposing individuals to
violent crimes, or mental health disorders, or other consequences later in life
(Li & Liu, 2013).
However, if congenital or hormonal notions
are implicated in the perpetuation of behavioral problems, they are far from
substantiating the full magnitude of the question. On the one hand, human
beings are not at the mercy of biological and hormonal mechanisms like animals,
especially, knowing that many children are only violent with their loved ones.
Rather, it is the interweaving of a whole multidimensional process. On the
other hand, the multiple facets of man do not allow the question to be
approached only from a biological angle. Other factors such as environmental factors
would have their explanatory weight.
The environmental perspective highlights the
importance of family and environmental factors in the development of behavior
problem in children. Several environmental factors contribute to a child’s
needs including separated or divorced parents, substance abuse in the home,
depression, mental health, and physical and verbal abuse (CDC, 2013).The role
of family and home plays a crucial part in children’s well-being. Parent’s
temperament and family environment are linked to parenting practices that might
promote (or inhibit) children’s effort control. The parent’s style of parenting
is a large component of how children display positive or negative behaviors[11]. Many children suffer from failures in
the family environment such as conflict, little family support, negative
parenting style, poor parent and sibling relationships, uninvolved parents, or
parents who show little interest in their child. Often, parents use negative
consequences and stress levels are elevated, which leads to more issues
occurring. Sometimes when parents are present, they do not use the best form of
discipline or have negative consequences that do not address the issue at hand
(Rallis, Esposito-Smythers & Mehlenbeck, 2015). If early behavioral
disorders do indeed appear to be multi-factorial, family and environmental risk
factors retain a significant and specific weight in their explanation and in
their development, as in therapeutic and preventive intervention (Greenberg,
1999; Rutter, 2001). It is clear, in fact, that parent /child relationships
play a major role in the development of behavioral problems, through the
experience and the type of emotional regulation they allow (Campbell, 1995;
Kazdin, 1995; Shaw and Bell, 1993; Rutter, 1995). Other studies using different
measures, methods, and raters consistently support the idea that substantial
genetic and small non-shared environmental influences contribute to the overlap
among ADHD, ODD, and CD (Taylor et al., 2012). In addition, a study of
nearly 40,000 Australian children aged 4 to 7 found that disadvantaged economic
status was the strongest predictor of behavioral and emotional difficulties
measured using the SDQ (Steele et al., 2015).
Overall, a mean worldwide prevalence of attention-deficit
hyperactivity disorder (ADHD), or hyperkinetic disorder (HKD), of ~2.2% overall
(range, 0.1–8.1%) has been estimated in children and adolescents (aged <18
years). The mean prevalence of ADHD in adults (aged 18–44 years) from a range
of countries in Asia, Europe, the Americas and the Middle East was reported as
~2.8% overall (range, 0.6–7.3%)[12].
Furthermore, the prevalence of ADHD in children and adolescents differ across
the world. Few
studies exist regarding ADHD prevalence rates in pre-school children (aged ≤6
years); however, prevalence rates in Norway, Germany and Spain have been
estimated to be 1.9%, 1.8% and 5.4%, respectively.2-4. An epidemiological study
of 20 countries from the World Health Organization that across high-,
upper-middle-, and low-/lower-middle-income countries, prevalence rates of ADHD
in children and adolescents were highest in the USA (8.1%) and lowest in Iraq
(0.1%), Poland (0.3%) and Romania (0.4%)[13].
Gender ratios varied by country
ranging from 1:3 to 1:16 in females: males[14].ADHD
was more commonly diagnosed in adult males compared with adult females. A
worldwide meta-regression analysis of 11 studies of adults with ADHD found that
although the ratio of males to females with ADHD decreased with age, a gender
ratio of 1 to 1.6 (females to males) was still present in adults aged ≥19 years[15].In
addition, a few
recent longitudinal studies are particularly important for understanding family
and environmental factors that play a role in the origin, onset and persistence
of behavioral disorders. This is in particular that of Moffitt et al. (2002),
known as Dunedin, in New Zealand, that of Fergusson et al. (1993, 2002) in
Christchurch, also in New Zealand, that of Nagin and Tremblay (2001) in
Montreal, and that of Loeber et al. (2001) in Pennsylvania and Georgia
(Developemental Training Study, DTS)[16].
However, research on genetic and
environmental influences on behavior has shown that individual differences in
behavior are associated with differences in genetic factors. This amounts to
saying that human behavioral traits are determined by biological, environmental
/ social and genetic factors.
Speaking of genetics here, and following the
normal curve of variation, no reference has been made to the environmental
extremes of abuse or the genetic extremes of single gene mutations that can
have devastating effects. Referring to Mendel's genetics, these are
deterministic effects wired to a single gene. But it is about the common traits
that are influenced by many low effect genes and the effects are probabilistic.
Everything is a matter of differences and it is quite an important notion for
the understanding of the human in his temporal space: past, present and future.
From this perspective, the emphasis is on
that concept of genetics called heritability which is the extent to which
differences in inherited DNA explain differences in behavior. It is shared by
the scientific community that in a studied population 99% of the DNA presents a
similarity that constitutes our basis of humanity. Which explains that 1% of
our 3 billion DNA base pairs make us different and to what extent do they
explain the differences in behavioral problems?
In fact, behavior problems can be influenced
by many factors including biological and neurological, family income, mother's
age level, school environment, and childhood problems, etc. All of these
factors have genetic and environmental predispositions. And even if we put
people in a similar environment and treat them equally, genes will continue to
make them different. In addition, studies[17]
on twins have shown that monozygotic twins with identical DNA and a similar
environment often exhibit different behaviors. Although twins are more similar
than other people, they are still different due to their personal experiences.
If twins who share the same genes and the same environment report differences
in their behavior, what can we conclude for the others?
By this observation, it was understood that
the environmental effects are not systemic, what looks like the systemic
effects of the environment is genetically disguised. Of course, they have a
role to play, but it is not the systemic influence of biological, family or
social factors that can determine a child's behavioral problems. Rather, it is
the important environmental influences that are called unshared, that is, what
really makes a unique person, different from others.
In fact, Since the completion of the human
genome project in 2003, it’s possible to understand the structure of the
genome. At this point, it’s shared that inherited DNA differences are the
primary systemic source that makes us who we really are as individuals. From
this DNA revolution, genetics became important and unavoidable in the study and
psychopathology of human behavioral problems.
Finally,
molecular research suggests that human traits may be regulated by genes[18]. For these
considerations, molecular and genomic approaches today constitute the best
avenues of research in understanding the differences in behavioral problems
because DNA is the main systemic force that makes us, in our children, what
they are.
