Assessed the validity of a brief form of the WAIS in the evaluation of several clinical populations. The short form was composed of three subtests: Similarities, Picture Arrangement, and Block Design. The sample consisted of 27 schizophrenics, paranoid type; 30 schizophrenics, schizoid‐affective type, 29 schizophrenics, chronic undifferentiated type; and 28 organics (brain syndrome patients). Correlations were computed between the weighted IQ scores of each population and the Fuli Scale IQ. Correlations of 0.94 for chronic undifferentiated schizophrenics and 0.81 for organics were particularly noteworthy. Moreover, this triad of subtests underestimated the IQ score for organics by 7.11 points, which suggests that the constant used with this population should be corrected appropriately.
