The OADP-CDS: a brief screener for adolescent conduct disorder

OBJECTIVES: To examine the ability of a very brief (6-item) self-report screener, the Oregon Adolescent Depression Project Conduct Disorder Screener (OADP-CDS), to identify adolescents with a lifetime diagnosis of conduct disorder and to examine its ability to predict antisocial personality disorder by age 24. Relevant scales from the Yough Self-Report and the Child Behavior Checklist were examined for comparison purposes. METHOD: A total of 1,709 high school students completed an initial questionnaire and diagnostic interview assessment (T1); 1,507 participants returned approximately 1 year later for a second assessment (T2). A third (T3) assessment was conducted with selected T2 participants (n = 940) after they had turned 24 years of age. RESULTS: The OADP-CDS had good internal consistency, test-retest stability, and screening properties. Differences in the screening ability of the OADP-CDS as a function of gender and social desirability were nonsignificant. The efficacy of the measure as a screener did not differ significantly from that of longer adolescent- and parent-report measures. Perhaps most importantly, the OADP-CDS was able to identify future cases of antisocial personality disorder in young adulthood. CONCLUSIONS: Results suggest that self-report screening for conduct disorder with older adolescents is possible and should be explored further.
