Determinants of maladaptive behavior of institutionalized mentally retarded individuals.

The maladaptive behavior of 474 persons from a residential facility for mentally retarded individuals was investigated. Eleven independent variables pertaining to demographic and environmental characteristics were initially related to the frequency and topography of residents' maladaptive behavior. Multiple regression analysis revealed that maladaptive behaviors were related to sex, social age, chronological age, resident's time spent on outside activities, number of residents per direct-care staff member, presence of sensory handicaps, and ambulation. Results were related to existing literature and discussed in terms of their use for intervention efforts and differential assignment of resources.
