Abstract
The Wechsler Intelligence Test, and specifically the fourth edition of the Wechsler Intelligence Scale for Children (WISC-IV), is one of the most widely used intelligence tests in the world. The aim of the present study was to examine gender measurement invariance in the Wechsler Intelligence Scale for Children (WISC-IV). The research methodology was applied in terms of its objective and was categorized as secondary analysis in terms of data collection. To achieve this, a random sample of 1,222 Iranian students (622 boys and 600 girls) was selected, and the Wechsler test was administered to them. The data collection tool was the fourth edition of the Wechsler Intelligence Scale for Children (WISC-IV). The data were analyzed using LISREL 8.7 software. For data analysis, multigroup confirmatory factor analysis was used. The results showed that the Wechsler Intelligence Scale exhibited all four types of invariances: configural invariance (RMSEA=0.037, χ²=321.67), weak invariance (RMSEA=0.031, χ²=270), strong invariance (RMSEA=0.034, χ²=326.76), and strict invariance (RMSEA=0.032, χ²=326.76). The invariance results indicate that the factor scores of the WISC-IV and its subscales have the same meaning for both boys and girls student groups. Therefore, the obtained results can be interpreted equally for both groups, allowing for meaningful comparisons between boys and girls.
