The relationship between IQ scores on the Full-Range Picture Vocabulary Test (FRPV) of Amnions and Amnions and the Wechsler Adult Intelligence Scale (WAIS) was investigated using a random sample of clients at a hospital-based vocational rehabilitation center. As predicted, correlations of FRPV and WAIS were significant, but decreased in magnitude for WAIS Vocabulary subtest, Verbal IQ, Full-scale IQ, and Performance IQ scores. These data extend previous research in applying the FRPV to different populations and suggest that it can be usefully applied as a quick screening measure of intelligence with a heterogeneous rehabilitation clientele.
