Abstract
Objective: The aim of this study was to compare the Persian version of the wechsler intelligence scale for
children - fourth edition (WISC-IV) and cognitive assessment system (CAS) tests, to determine the correlation
between their scales and to evaluate the probable concurrent validity of these tests in patients with learning
disorders.
Methods: One-hundered-sixty-two children with learning disorder who were presented at Atieh
Comprehensive Psychiatry Center were selected in a consecutive non-randomized order. All of the patients
were assessed based on WISC-IV and CAS scores questionnaires. Pearson correlation coefficient was used to
analyze the correlation between the data and to assess the concurrent validity of the two tests. Linear
regression was used for statistical modeling. The type one error was considered 5% in maximum.
Findings: There was a strong correlation between total score of WISC-IV test and total score of CAS test in the
patients (r=0.75, P<0.001). The correlations among the other scales were mostly high and all of them were
statistically significant (P<0.001). A linear regression model was obtained (α=0.51, β=0.81 and P<0.001).
Conclusion: There is an acceptable correlation between the WISC-IV scales and CAS test in children with
learning disorders. A concurrent validity is established between the two tests and their scales.
