those
usually first diagnosed in childhood or
adolescence
BEHAVIORAL DISORDERS OF
CHILDHOOD AND ADOLESCENCE:
General
á
Childhood is 20th century concept
á
Unknown if prevalence has changed over
time
Note:
Prevalence mostly determined by what
adults
find to be acceptable behavior
STRESSORS IN MODERN CHILDHOOD:
General
á
Stressors ð increased risk of
psychological disorders
(Flisher
et al., 1997)
á
25% Severe physical abuse

40% had seen dead bodies in their
neighborhood

Most children who face major stressors
do NOT
develop a psychological disorder

psychological disorders have not had a major stressful life event
Stressors do not sufficiently explain vulnerability
STRESSORS IN MODERN CHILDHOOD:
Resilience
á
At least one healthy, competent, &
reliable adult
o
e.g., Masten et al. (1993) - same
resilience among homeless children who have a relationship with a competent
adult
o
e.g., Plomin (1994) - same resilience
for children with "difficult" temperament
