Abstract: (1 Views)
Background and Objectives: Agrammatism, a disorder characterized by difficulties in producing complex syntax, reduced verb use, and the omission of grammatical morphemes, significantly impacts speech production and comprehension. Given the prevalence and impact of grammatical deficits, assessing agrammatism is essential for diagnosing and treating affected individuals. This study aimed to translate, culturally adapt, and develop the northwestern anagram test (NAT) in Persian to assess agrammatism in Persian-speaking populations.
Methods: The syntactic structures of Persian were analyzed to design test items, including 33 sentences and related images. In addition, content validity was evaluated by 11 experts, comprising seven speech-language pathologists and four linguists, using the content validity ratio (CVR) and content validity index (CVI). Sentences and images that scored below threshold values were revised or replaced, and the mean CVR and CVI scores were calculated for the remaining items to confirm validity.
Results: The Persian version of NAT (P-NAT) demonstrated satisfactory content validity, with a mean CVR of 0.85 and a CVI exceeding 0.79 for all items. Expert feedback was incorporated to refine test items and illustrations, ensuring cultural and linguistic appropriateness.
Conclusion: P-NAT is a promising tool for assessing agrammatism. Future research should evaluate its psychometric properties, including construct validity and reliability, to establish its clinical applicability.
