Usefulness of the WAIS-IV Short Form for Measuring Cognitive Function in Patients With Schizophrenia.

ABSTRACT: Schizophrenia causes cognitive dysfunction. The assessment of cognitive function is important in the treatment of schizophrenia. The Wechsler Adult Intelligence Scale (WAIS) is used to assess cognitive function in patients with psychiatric disorders. For clinical use, a short form of the WAIS-III was developed in Japan specifically for patients with schizophrenia, allowing the estimation of IQ using the Similarities and Symbol Search. In the present study, we examined whether the same tasks could be used on the short form of the WAIS-IV. The subjects were 110 patients with schizophrenia. Using methods consistent with those employed in developing the WAIS-III short form, exploratory factor analysis was conducted to confirm the factor structure of intelligence in patients with schizophrenia.
