Conduct disorder : an analysis of subtypes.
J Pak Psych Soc Jan ;8(2):62-8.

Objective: This study sought to identify cormorbidity, aggression, hostility and severity across the subtypes of CD based on the age of onset as per the DSM-IV criteria. Design: Descriptive study. Place and duration of the study: This study was carried out in a private psychiatric clinic in Mumbai between January 2007 and January 2008. Subjects and Methods: Referred children aged 7-16 years old were clinically assessed using clinical interviewing to determine comorbid psychiatric diagnoses. The Modified Overt Aggression Scale (MOAS), Buss Durkee Hostility Inventory (BDHI), Clinical Global Impressions Scale (CGI) and Clinical Global Assessment Scale (CGAS) were used in quantitative assessment. Parental psychiatric diagnosis was ascertained via clinical interview. Results: Childhood onset CD was associated with greater rates of ADHD, anxiety disorders, complex cormorbidity, higher perceived hostility scores and lower rating on the CGAS scale than adolescent onset CD. Greater number of mothers in the childhood onset CD group had borderline personality disorder. Both parents across the group had high rates of major depression while fathers across both groups showed the presence of alcohol and nicotine dependence. Conclusion: Understanding age of onset related patterns of comorbidity and psychopathology may help therapeutic intervention in children and adolescents with CD.
