Abstract :

This study aimed to determine the validity and reliability of the Wechsler Intelligence Scale for Children- Fourth Edition (WISC-IV) among students between the ages of 6 and 16 from Chaharmahal & Bakhtiari State. In order to examine the validity of WISC-IV, the Raven's Standard Progressive Matrices (SPM) (Raven, 1938) and the Wechsler Intelligence Scale for Children-Revised (WISC-R; 1974) were used. The validity results indicated significant correlations among WISC-IV, SPM, and WISC-R in related sections. The scale reliability was examined using test – retest and split-half methods. The split-half reliability coefficients of all subscales were adequate to very good. The test-retest reliability coefficients showed that all subscales except picture concepts were adequate to very good too. In addition of assessing IQ of individuals between the ages of 6 and 16, this scale can be used for diagnosing learning disorder, attention deficit disorder, brain injury, anxiety and obsessive compulsive disorders.
