We selected a sample of patients with depression ( N = 70) and used Bayesian analyses to examine the diagnostic predictive validity of the Wechsler Adult Intelligence Scale‐Revised Verbal IQ (VIQ) minus Performance IQ (PIQ) difference score for depression. The patients showed average VIQ‐PIQ differences in the expected direction (i.e., VIQ > PIQ). However, based on sensitivity, specificity, and positive predictive value statistics, we concluded that the VIQ‐PIQ split has very low predictive validity in persons with depression. © 1999 John Wiley & Sons, Inc.
