A Factor Analysis of Emotional Disorders in Mentally Retarded People

Abstract
A factor analytic study of a symptom checklist was conducted with 131 emotionally disturbed, mentally retarded people who were outpatients at a developmental disabilities mental health clinic in Chicago, Illinois. Item loadings of .40 or greater were used as the criterion for inclusion in factors. Scores reflecting the frequency of significant occurrences of each symptom also were computed. The results of the study add statistical detail to previous clinical reports on the symptoms of emotional disturbances in mentally retarded people.
