Abstract

Aim: This study was aimed at investigating the basic structure of WISC-IV using multidimensional scaling and Confirmatory Factor Analysis and comparing the results to the assumed model. Method: Design of the study was correlational. Out of 1314 male students studying at 6th distinct of Tehran, 200 were sampled using cluster sampling method. Wechsler intelligence test for children-Fourth edition was used to assess intelligence. Gathered data were analyzed using multidimensional scaling and confirmatory factor analysis. Results: MDS resulted in 3 separate dimensions (processing speed, presentation mode and response mode) (Stress = 0. 021, P = 0. 04). 4-factorial model was not admissible (χ 2 = 102. 63, P = 0. 04). However, fit indices of Second-Order Confirmatory Factor Analysis along with some modifications confirmed the 3-factorial model (χ 2 = 99. 00, P = 0. 055). Conclusion: According to the results WISC-IV scores could be better understood using 3 factorial solution rather than the existing 4-factorial structure so it is suggested that 3-factorial solution could be used in clinical context and for counseling purposes.
