Children with learning disabilities in four types of special education settings were compared in terms of social acceptance, number of friends, quality of relationship with best friends, self-concept, loneliness, depression, social skills, and problem behaviors. Two of the placements (In-Class Support and Resource Room) were for children with mild to moderate learning disabilities and involved between 30 and 90 minutes of special education per school day. The other two placements (Inclusion Class and Self-Contained Special Education Class) were designated for children with severe learning disabilities and involved at least a half-day of special education. Children in the more inclusive placements had more positive social and emotional functioning. Children receiving In-Class Support were more accepted by peers, had higher self-perceptions of mathematics competence, and fewer problem behaviors than children receiving Resource Room Support. Children in Inclusion Classes had more satisfying relationships with their best school friends, were less lonely, and had fewer problem behaviors than children in Self-Contained Special Education Classes.
