| This research has been carried out with the aim of adaptation, standardization and finding the validity and reliability of TOLD-P:3 for Farsi- speaking children. A multi- stage sampling from the Farsi- speaking children of the city of Tehran resulted in a sample of 1235 subjects (625 boys and 609 girls) ages 4, 0 through 8,11. The test consisted of 9 subtests (6 core subtests and 3 supplemental ones). Moreover; by combining the scores of the core subtests, 6 compound scores were obtained. For adaptation and standardization of this test, at first step the examiner's manual and the test items were translated into Farsi; then in accordance with the syntactic, semantic and phonological features of Farsi and considering the theoretical bases of the test, most of its items were revised or changed. The final form of the test was obtained after performing the pre- tryout and tryout stages, and doing the data analysis by the classic model of reliability. Internal consistency coefficients of the subtests were obtained by Cronbach's Alpha; time consistency of the subtests and the compound scores were obtained by test- retest. Alpha coefficients for the compound scores were obtained by Guilford formula which is designed for estimating the compound scores. To obtain the content validity, criterion -related validity and construct validity of the subtests and compound scores, appropriate methods were used. The results obtained ensure the applicability of this test for the evaluation of language skills of Farsi - speaking children of Tehran. |
