Methods: The present study was conducted in two phases. In the first phase, by literature search, the screening test was designed and to obtain validity it was peer reviewed by expert panel. After collecting experts’ ratings and comments, appropriate modifications were applied. For test-retest reliability in the second phase, edited test was administered in 32 patients with brain injuries, then the retest was performed two weeks later. Results: The developed test had eight subscales including: A) picture description, B) syntax, C) linguistic reasoning, D) descriptive naming, E) perception of minimal pairs, F) comprehensive vocabulary, G) expressive vocabulary, H) verbal fluency. Each section had five questions except verbal fluency which had 3 items. Content validity ratio (CVR) according to Lawshe’s approach, was 82% for the whole test. Intraclass correlation for all subscales were more than 0.8. Cronbach’s alpha coefficient for internal reliability was 0.901. Conclusion: This aphasia screening test seems to have acceptable psychometric properties. This test can probably be used in clinical setting by specialists. https://ijnl.tums.ac.ir/index.php/ijnl/article/view/1085 https://ijnl.tums.ac.ir/index.php/ijnl/article/download/1085/304
