Persian Abstract Reasoning Scale: Development and Evaluation of Psychometric Properties

Abstract reasoning can evaluate by verbal scales. Because verbal tests impressed by language and culture¡ developing verbal test of persian language in order to evaluate abstract reasoning is necessary. The purpose of the present study was to design a persian verbal test to evaluate abstract reasoning and to determine its validity and reliability.
Material: The statistical population of the study were elementary students of tehran in 1393-1394. The sample included 239 student with age range 8 to 12 years old that selected by Convenience Sampling scheme. Pearson test was used in order to investigate concurrent validity between results of abstract reasoning and verbal fluency test. Two halves method and Cronbach''s alpha test was used in order to evaluate reliability. Discriminative validity was achieved from comparing average scores of age groups.
Subscales of abstract reasoning scale and verbal fluency test had a positive significant correlation with each other. Retest reliability of abstract reasoning scale based on two tests run and internal consistency of the test based on Cronbach’s alpha coefficients in sample group was confirmed. comparing between groups indicated on the discriminative validity of the test.
Persian Abstract Reasoning Scale is a valid and reliable test for measuring abstract reasoning.
