The move from formal institution living to an independent type of living situation was assessed in 18 mentally retarded adults with high (61-84) and low (56-39) IQ scores. Prior to and 6 months after the semi-independent living situation, Ss were administered the following measures: the Wechsler Adult Intelligence Scale, the AAMD (American Association on Mental Deficiency), Adaptive Behavior Scale, Burk's Behavior Rating Scales, a taped personal interview, and participation-observation situations where Ss were visited several times in their apartment. Among findings were that while none of the Ss could be deinstitutionalized, they can successfully live in a semi-independent type of living situation; that IQ does not play a role in adapting to the new environment; and that living in a more independent environment for 6 months does not help Ss to function more independently.
