Factor analysis of the WAIS-R and Verbal Memory and Visual Memory Indices of the Wechsler Memory Scale--Revised, for a vocational rehabilitation sample.

Few empirical studies have examined factor structures of responses of vocationally impaired persons, and those studies have drawn only on aptitude scores (Wechsler Adult Intelligence Scale--Revised: WAIS--R). Results have been inconclusive as to whether a two- or three-factor solution is more appropriate. The present work examined the factor scores of a vocational rehabilitation sample of 54 adults who had been given the WAIS--R and the Verbal Memory and Visual Memory Indices of the Wechsler Memory Scale--Revised. Analysis indicated that combining data from the two tests yields a viable three-factor solution which may contribute to the refinement of intervention strategies for vocationally vulnerable adults.
