Differentiation of organics from functional psychiatric patients across various IQ ranges using the Bender-Gestalt and Hutt Scoring System.

This study investigated the effectiveness of the Hutt Scoring System (Hutt, 1977) in differentiating organic from functional psychiatric patients, the relationship of IQ to Bender-Gestalt errors as measured by this scoring system, and examined the discriminative power of this scoring system for various IQ ranges. One hundred eighty patients were utilized, 90 of whom had been classified as organics and matched with the remaining 90 subjects on the basis of age, education, and IQ range. In addition, the organic subjects' secondary diagnosis was matched with the primary diagnosis of the nonorganic patients. Results between WAIS IQ and Hutt error scores for organic subjects yielded an r = -.34 (p less than .01); between WAIS IQ and Hutt error scores for the nonorganic subjects, r = -.61 (p less than .001). No significant results were obtained for organics and nonorganics simultaneously within the same IQ cells.
