This study investigated the validity of assessing self-concept in adolescents with a developmental disability and the relation between self-concept and depressive symptoms. Each adolescent and one of his or her parents and teachers provided reports on the emotional and behavioral functioning of the adolescent. Domains of self-perception were found to be reliable, multidimensional, and significantly related to theoretically consistent behavior. Adolescent report of global self-worth was related to self-report but not parent and teacher reports of depressive symptoms. The domains of behavioral conduct and physical appearance were most predictive of global self-worth; the domain of behavioral conduct was predictive of depressive symptoms. This study lends support to the validity of using self-assessment of emotional and behavioral difficulties in individuals with a developmental disability.
