ABSTRACT
Short form of the Wechsler Adult Intelligence Scale is often needed to quickly estimate intelligence for time-saving or screening in clinical practice. The present study aims to examine the psychometric properties of Chinese version of the four-subtest index-based short form (SF4) of WAIS-IV (FS) and to confirm its clinical application. 1,757 adults from the WAIS-IV Chinese version standardization sample and 239 mixed clinical samples including patients with schizophrenia or schizoaffective disorder (SCH), obsessive-compulsive disorder (OCD), and mild or moderate intellectual disability (ID) were used. Demographic data were collected and intelligence was assessed with WAIS-IV. The SF4 split-half reliability, test-retest stability coefficients and corrected SF4-FS correlations were good to excellent. The result of the Bland-Altman plot showed that the difference fell within 2SD was 95% and indicated a random error. The sensitivity, specificity positive predictive value (PPV), and negative predictive value (NPV) of the stepwise screening were good. There was an interaction (p < .001) between the IQ level (≥111) and gender on the accuracy of SF4, SF4 might get underestimated on females with the IQ level (≥111) than on males. In conclusion, SF4 is a valid and reliable instrument for use in the clinic, and its clinical application, stepwise screening and influencing factors in clinical use are discussed herein.
