Relationship of Anxiety and Depression Scores to WAIS Performance of Psychiatric Patients

Abstract

Relationships between the D scale of the Minnesota Multiphasic Personality Inventory (MMPI) and the Taylor Scale of Manifest Anxiety and the Wechsler Adult Intelligence Scale were investigated in 464 acute psychiatric inpatients divided into four age-sex groups. Bivariate product-moment and multiple regression coefficients were obtained between Taylor's scale and D scale scores and both relative and absolute WAIS subtest scores, Verbal IQ, Performance IQ, and Full Scale IQ. 21 of 288 first-order and 7 of 144 multiple regression coefficients were significant. 18 of 21 significant first-order correlations occurred on timed subtests. IQ range had little effect on the magnitude or pattern of relationships obtained. With the exception of the Block Design there was little evidence of any systematic relationship between WAIS performance and either the anxiety or depression scale scores.
