Sažetak
The Wechsler Intelligence Scale for Children, Fourth Edition, WISC-IV (Wechsler, 2003 ; WISC-IV-HR, 2009) is one of the world’s most commonly used measures of intelligence for children and adolescents. It has 10 core and 5 supplemental subtests, which are combined into 4 index scores and a total IQ score. So far, all of the knowledge and clinical experience with earlier versions of the WISC shows that there is a significant variability in test results for healthy children and adolescents on tests that consist of different subtests (battery of tests), and also that extremely low scores on these subtests aren’t unusual. The aim of this study was to examine the variability of scale scores and the frequency of extremely low scores on WISC-IV-HR subtests and indexes for the Croatian standardization sample. Scaled scores on 10 core subtests and 4 indexes where included in the analyses. Participants were 1200 children (608 male, 592 female) between 6 and 16 years and 11 months of age. The sample was stratified by age and county according to the population census. Information about parental education was also gathered. Consistent with previous studies, frequencies of extremely low scores on some WISC-IV-HR subtests were related to the lower total IQ score and parental education. Also, healthy children and adolescents have an average difference of 7 scaled scores (2.3 SD) between their highest and lowest subtest. This demonstrates that healthy children and adolescents can achieve scores on some subtests that are indicative of cognitive impairment. It was shown that the probability i.e. frequency of extremely low scores on some WISC-IV-HR subtest or index is decreased with higher child or adolescent intelligence and with higher parental education level. So, we should be careful when interpreting the results because significant result variability is present even in results of healthy children and adolescents.
