Self-reports of depression by community-based mildly mentally retarded adults.

Three self-report measures of depression were administered to mildly mentally retarded adults who lived in the community. The measures were significantly correlated, and on two of the measures subjects scored significantly higher than did nonretarded adults according to norms. Almost half of the subjects scored in the "clinically significant" range on the two measures. Results suggest that mildly retarded adults may experience depression at a higher rate than do nonretarded persons.
