Adolescent-Parent Agreement on Callous-Unemotional Traits in Adolescents with Attention-Deficit/Hyperactivity Disorder.

This study examined the levels of agreement between the reports of 207 adolescents with attention-deficit/hyperactivity disorder (ADHD) and their parents regarding the adolescents' callous-unemotional (CU) traits and investigated the factors influencing adolescent-parent agreement. Adolescent-parent agreement about CU traits in three dimensions according to the Chinese version of the Inventory of Callous and Unemotional Traits was examined. The influence of demographic characteristics, comorbid conduct disorder (CD), oppositional defiant disorder (ODD), and ADHD symptoms on adolescent-parent agreement was also examined. The results indicated that adolescent-parent agreement on the CU trait of uncaringness was moderate, whereas agreement on the CU traits of callousness and unemotionality was poor. Adolescent-parent agreement on the three dimensions of CU traits varied depending on the adolescents' sex and comorbid CD and ODD symptoms as well as parental age. Therefore, multiple sources of information are required when assessing the severity of CU traits in adolescents with ADHD. The factors influencing the levels of the agreement should also be considered.
