Depression and psychopathology were assessed in 110 adult patients (ages
18-71 years) classified as borderline, mildly, moderately, or severely
mentally retarded. Patients completed modified versions of the Beck
Depression Inventory, the Zung Self-Rating Depression Scale, the MMPI
depression scale, the Thematic Apperception Test, and the Psychopathology
Instrument for Mentally Retarded Adults. Clinicians and ward personnel
rated the patients on the Hamilton Rating Scale for Depression and an
informant version of the Psychopathology Instrument for Mentally Retarded
Adults. The measures correlated significantly with each other and were
consistently related to the diagnosis of depression.Abstract Teaser
