How young adults\u27 perceptions of their relationships with their siblings with Attention Deficit Hyperactivity Disorder differ from the perceptions of other young adults having non-disordered siblings were examined. Participants\u27 perceptions of warmth, conflict, and rivalry with their siblings were measured using the Adult Sibling Relationship Questionnaire. The results indicated that perceptions of warmth, conflict, and rivalry were not significantly different for these two groups. An inverse relationship between warmth and rivalry was found for participants having siblings with ADHD. As feelings of warmth increased, feelings of rivalry decreased. Findings suggest future research in this area is needed for results that are more conclusive
