This study examined data from the Special Education Elementary Longitudinal Study (SEELS, 2003) to compare the social skills of children in the U.S. with comorbid learning disabilities and attention-deficit/hyperactivity disorder (LD+AD/HD) to their peers with LD-only and AD/HD-only, and to assess how specific demographic factors moderate the relationship between disability status and social skill. Results showed that the social skills deficits of children with comorbid LD+AD/HD were more marked than those of children with LD-only. Additionally, family involvement significantly moderated the relationship between disability status and social skill, with increased family involvement associated with increased social skills among children with comorbid LD+AD/HD and AD/HD-only.
