Background: Learning disability is one of the most common learning disabilities that can cause many problems in other areas of learning, social, emotional and behavioral. Therefore, early intervention in individuals with reading difficulties is an educational and therapeutic priority. For timely intervention, assessment and diagnosis of individuals with reading disabilities is a very important step.
Aims: This study aimed to investigate the effectiveness of the Jahesh Reading Test in diagnosis of dyslexia in Persian-speaking children in the first period of elementary school.
Methods: The present study was an applied test-making study. The statistical population was the first-year elementary school students in Tehran in 2023-2024. A sample of 700 first-year elementary school students was selected by random sampling method and was evaluated with the Jahesh reading test. Content validity was evaluated by the opinion of ten experts using the Content Validity Index (CVI). Diagnostic validity was evaluated by comparing the reading test between groups using the t-test, and developmental construct validity was evaluated by comparing the educational levels in the reading test using the F-test and reliability using the Kuder-Richardson coefficient and test-retest using SPSS and AMOS software.
Results: The results of comparing the average scores of the first grade reading test between the normal and learning- disabilities groups indicate significant differences in all subtests. These results indicate that children with learning disabilities performed significantly worse than normal children in all aspects related to reading skills, and the reading test was able to identify these differences well. Also, the results of comparing the average scores of the reading test in the first, second, and third grades of primary school indicate a significant improvement in reading skills with increasing age and educational level. In general, in most subtests, the average scores of students in higher grades are higher than those in lower grades, and the differences are statistically significant (p< 0.001).
Conclusion: The results of the study show that the Jahesh Reading Test has diagnostic validity and can be used to diagnose dyslexia in Persian-speaking children in the first period of elementary school.
