Abstract:

Background and Objective: The Communicative Effectiveness Index (CETI) is a brief assessment scale designed to measure changes in the functional communication ability of persons with post-stroke aphasia. The objective of the present study was to translate the CETI to Persian language and measure its cross-cultural adaptation, validity, and reliability in persons with aphasia. Materials and Methods: The Persian CETI (P-CETI) was developed according to Beaton and colleagues’ guidelines for the procedures of cross-cultural adaptation of measures. A cross-sectional study was conducted to examine its psychometric properties in 35 patients with aphasia. Internal consistency and test-retest reliability of the P-CETI were evaluated using Cronbach’s alpha and the intra-class correlation coefficient (ICC), respectively. Concurrent validity was examined by correlating the P-CETI with the Functional Communication Performance Questionnaire in Adults with Brain Injury (FCP). Findings: The mean total P-CETI score was 82.89±40.61 (range: 24-148). Cronbach’s alpha coefficient was 0.97, and all corrected item-total and inter-item correlations were in the acceptable range. The P-CETI also showed good test-retest reliability, with ICC = 0.99. There was no floor or ceiling effects in the total P-CETI score. The P-CETI significantly correlated with the FCP, indicating acceptable concurrent validity. Conclusion: The Persian version of the CETI (P-CETI) was successfully translated and showed very good internal consistency and test-retest reliability. Therefore, the P-CETI can be considered as a valid and reliable tool for the assessment of functional communication in Persian-speaking persons with aphasia.
