Self-concepts of adolescent siblings of children with mental retardation.

Self-concepts of 70 adolescent siblings of children with profound levels of mental retardation were investigated. Their mean self-concept was compared with a matched group of 70 adolescent siblings of children without profound levels of retardation. Using the Tennessee Self-concept Scale, two variables (maternal self-concept and siblings' self-concept) were assessed for differences between siblings and mothers (the target group) of mentally retarded children and siblings and mothers (the comparison group) of children without mental retardation. No significant mean difference between the two groups suggests no special difficulties in psychosocial adjustment for siblings of the mentally retarded.
