A canonical correlation between adaptive and maladaptive aspects of adaptive behavior.
The relationship between the adaptive and the maladaptive aspects of the construct of adaptive behavior was examined by means of a canonical correlation between Part One and Part Two of the AAMD Adaptive Behavior Scale (ABS). The sample consisted of 439 institutionalized mentally retarded persons. Four significant canonical correlations (.68, .49, .39, .28) were derived, three of which were interpretable. The redundancy index was 30 percent with Part One as the criterion and 14 percent with Part Two as the criterion. A redundancy of about 30 percent was calculated. An analysis of the pattern of canonical components suggested that the three major dimensions responsible for the overlap between ABS Parts One and Two are intellectual ability, sociability, and physical ability. An attempt to cross validate these results was made using another sample of 157 mentally retarded persons. Considerable shrinkage was observed on three of the roots.
