Item-domain relationships in the Adaptive Behavior Scale (ABS)
Abstract:
The internal consistency reliability of the domains on the Adaptive Behavior Scale was examined using ratings provided by client care-staff on 265 institutionalized, mentally retarded persons. Nine of the 10 Part I domains and 6 of the 14 Part II domains had coefficient alpha reliabilities of .80 or greater. An item analysis was obtained by correlating each ABS item with each domain score. About 62% of Part I items and 61% of Part II items were judged as satisfactory by item analytic criteria. The implications of these results for users of the ABS were discussed.
