Wr. Lindsay et al., THE CONSISTENCY OF REPORTS ABOUT FEELINGS AND EMOTIONS FROM PEOPLE WITH INTELLECTUAL DISABILITY, JIDR. Journal of intellectual disability research, 38, 1994, pp. 61-66
Sixty-seven subjects with mild or moderate intellectual disability wer
e assessed on a variety of measures of emotion. All of the measures we
re self-report measures and all of the data is based on reports by the
subjects' themselves. The battery included the Zung Self-Rating Anxie
ty Scale, the Zung Depression Inventory, the General Health Questionna
ire and the Eysenck-Withers Personality Test. The results reveal an im
pressive amount of convergent validity in the subjects' emotional syst
ems.
