Social Status and the Comorbidity of Child Depression and Conduct Disorder

This study examined the overlap between child depression and conduct disorder (D & CD) as a function of peer social status (i.e., popular, rejected, neglected, controversial, average) in a sample of 1,464 nonreferred 4th graders. Both D&CD were measured by self-report, peer nomination, and teacher ratings. Social status was assessed by peer nomination. A strong correlation (.73) was found between D&CD, even after accounting for shared method variance by confirmatory factor analysis. Furthermore, the number of Ss who scored high on both D&CD was greater than would be expected by chance alone. Multivariate tests revealed that rejected Ss scored higher than average Ss on measures of D&CD. Controversial boys also scored higher on measures of CD. However, analyses also revealed that the association between depression and rejected social status might be due to a subgroup of depressed children who also manifested symptoms of CD. Implications for assessment and treatment of child disorders are discussed.
