This study examines attention-deficit/hyperactivity disorder (ADHD) and callous-unemotional (CU) traits as moderators of the association between conduct problems (CP) and young adult functioning. Young adults (n = 283; Mage = 20.82 years; 53.4% female), oversampled for attention and behavior problems, provided self-ratings of ADHD, CP, and CU, and adaptive functioning and psychopathology. ADHD and CU simultaneously moderated relationships between CP and family functioning, tobacco use, and internalizing symptoms. In addition, ADHD moderated the relation between CP and job functioning, and main effects of ADHD in the expected direction were found for educational performance and drug use. CU was associated with poorer educational outcomes. Interestingly, no ADHD, CU, or CP effects were observed for reported alcohol use. Our results highlight the importance of considering ADHD and CU in understanding the impact of CP on young adult functioning and psychopathology, and point to the importance of continued work on this topic.
