Abstract This study aimed to describe problem behaviors and psychosocial strengths, examine the problem-strength interrelations, and evaluate profiles of problems and strengths in youth with Down syndrome (DS). The community-based sample consisted of 67 parents of children with DS aged between 4 and 19 years. Parents reported about the developmental age (Vineland screener), behavioral problems (Child Behavior Checklist), and psychosocial strengths (Behavioral and Emotional Rating Scale) of their child. Results indicate that attention, social, and thought problems were most prevalent, whereas family involvement and receiving/expressing affection were identified as strengths. A confirmatory factor analysis identified problems and strengths as distinct, yet related, variables. Moreover, a cluster analysis of problems and strengths identified four different profiles. Implications for interventions are discussed.
