Parent-Adolescent Agreement on Disruptive Behavior Symptoms: A Multi-trait Multimethod Model


This study examined parent–adolescent agreement on reports of inattention, hyperactivity/impulsivity, and conduct disorder in 203 adolescents (94 girls, 109 boys) ranging in age from 13 to 18 years (M = 15.21, SD = 1.37). Results of confirmatory factor analyses provided additional evidence of construct validity for these traits in adolescents. Internal consistency was examined for parent reports and adolescent self-reports. In addition, correlational analyses were used in a multitrait-multimethod format (MTMM; D. T. Campbell & D. W. Fiske, 1959) to examine convergent and discriminant validity. Results showed that parents provided more consistent and valid reports of inattention and hyperactivity/impulsivity, whereas adolescents provided more consistent and valid reports of conduct disorder. In addition, interviews produced higher levels of convergence than rating scales. These findings are discussed in terms of implications for assessment of disruptive behavior disorders.
