A Paramorphic Representation of Psychologists' Clinical Impressions of Degree of Mental RetardationWoodhaven Center
Woodhaven Center
Woodhaven Center The purpose of this study was to develop a paramorphic representation of the clinical decision-making procedure used by psychologists in combining IQ and adaptive behavior information to arrive at a diagnosis of degree of mental retardation. The data consisted of the clinical judgments formed by 8 psychologists on 180 mentally retarded individuals. The psychologist-assigned levels of mental retardation classifications were regressed on IQ and 23 domain scores from the Adaptive Behavior Scale. IQ alone had a correlation of .83 with this classification. A linear combination of IQ, Independent Functioning, Vocational Activity, Physical Development, and Economic Activity resulted in a multiple correlation of .87. Various interpretations of these results are discussed.
