Answer 1:
Let me preface my answer to these questions
with two comments. One, I am not an expert in
this field but will try and answer the questions
based on some readings I have done. Two, if these
question are specific towards a person or group of
people I would suggest that you seek a
professional opinion or evaluation.
From what I
have been able to learn, people (usually children
and adolescents) do not "come down with" conduct
disorder or antisocial behavior, it is not like
the flu. Instead a series of factors may play a
role in the diagnosis of these conditions. A
specific genetic determination has not been
found but since it sometimes runs in families
there may be a genetic predisposition towards
having these disorders. This is not to say that if
you are or are not predisposed that you definitely
will or will not display these behaviors.
It seems that environmental factors
probably play a bigger role
in the onset of these disorders. Again, exact
factors have not been established and so children
with these disorders may or may not be from
"broken homes" or impoverished. While stories seem
to abound about males and middle children being
more prone to these conditions there has not been
a reliable study on propensity of one gender over
the other to be diagnosed with either of these
disorders. Finally, about 6% of the population
has been diagnosed with conduct disorder. An
exact number is probably impossible to determine
since diagnosis is not a strict test but just the
opinion of medical doctor or psychologist. |
