Relationship of depressive, conduct, and comorbid disorders and social functioning in childhood.

OBJECTIVE: To examine the relationship of depressive, conduct, and comorbid disorders and social functioning in psychiatrically referred youths.
METHOD: Subjects were 94 boys and 67 girls (mean age at initial assessment = 11.5 years) who were repeatedly evaluated with standardized instruments during a mean interval of 4.4 years. On the basis of their diagnoses during the follow-up, children were designated as having had depressive, conduct, or both (comorbid) disorders or other conditions. Two domains of social functioning were assessed: social competence and self-esteem.
RESULTS: Longitudinal analyses revealed that at any given point in time, depressive, conduct, and comorbid disorders were associated with low social competence and depressive disorder also was associated with low self-esteem. At the approximate age of 15 years, on average, children with a history of conduct or comorbid disorders had lower social competence than did children with a history of depressive disorder, but these groups endorsed similar levels of self-esteem.
CONCLUSION: Some areas of social dysfunction associated with comorbid depressive and conduct disorders appear to reflect mostly the effects of conduct disorder. The latter condition has a more severe and longer-term impact on children's social competence than does depression. In addition, whereas depression has an adverse effect on self-esteem, this effect appears to be temporary.
