The consistency of reports about feelings and emotions from people with intellectual disability

Sixty-seven subjects with mild or moderate intellectual disability were assessed on a variety of measures of emotion. All of the measures were self-report measures and all of the data is based on reports by the subjects' themselves. The battery included the Zung Self-Rating Anxiety Scale, the Zung Depression Inventory, the General Health Questionnaire and the Eysenck-Withers Personality Test. The results reveal an impressive amount of convergent validity in the subjects' emotional systems.
