| Summary: | Brief intelligence tests are defined as cognitive tools that can be applied quickly, provide information about the general characteristics of intelligence, but offer a relatively narrow measurement framework. The international literature has many studies comparing the first version of the Kaufman Brief Intelligence Test (KBIT; Kaufman & Kaufman, 1990) with the different versions of the Wechsler Intelligence Scales (i.e., WISC-R [Prewett, 1992a, 1992b], WISC-III [Prewett, 1995]), both psychometrically and clinically. However, the national norm studies of the Second Version of the Kaufman Brief Intelligence Test (KBIT-2) in Türkiye have been completed recently. This study evaluates within its scope the structural features of KBIT-2, which is a fairly new measurement tool for Türkiye, by comparing them with WISC-IV. The study includes a total of 103 primary and high school students between 6-15 year old living in Ankara. Psychologists with practitioner certificates administered the tests to the participants with a one-week break in between, starting with WISC-IV and followed by KBIT-2. The findings indicate a significant correlation to exist between the total score on KBIT-2 and the total score on WISC-IV (r = .62). KBIT-2 scores were observed to be significantly higher than the WISC-IV scores. In addition, the composite scores and subtest standard scores for the scales were observed to show certain patterns, with the findings indicating the results obtained from the KBIT-2 test to be interpretable within the Cattell-Horn-Carroll (CHC) theory and the results to be comparable to those obtained from the WISC-IV. Again, the results from this study indicate the most beneficial use of KBIT-2 to likely be for screening rather than for diagnostic purposes. The most important limitation of the study is its small sample size, and future studies can make very valuable contributions by studying the distinguishing power of KBIT-2 in special samples such as gifted or intellectually impaired children. |
