ABSTRACT

This study examined the psychometric properties, including validity, of the K-WAIS-IV short forms (SFs) proposed by Choe et al. (2014) when applied to psychiatric patients. The SF A and B are the two subsets (arithmetic, information) and four subsets (arithemetic, information, matrix reasoning, coding) that were introduced by Choe et al. (2014). The results of the validity test indicated that both SF A and B were not valid for the entire study group. In order to confirm the practical usefulness of the SF test, the group was classified by intelligence level; the SF test was applied, but it was not valid. Further, the diagnostic concordance rate was especially low when SF A was applied to the group with low intelligence. In addition, the SFs were not appropriate when administered for each diagnostic criterion such as anxiety disorder, depressive disorder, neurocognitive disorder, psychotic disorder, and mental retardation. The implications and limitations of the study, as well as suggestions for future research, were discussed, and cautious and more conservative attitude of clinicians toward the use of SF tools was also discussed.
