Abstract

Objective: To translate and validate the confidence communication rating scale for aphasia (CCRSA) in Urdu.
Methodology: Current cross-cultural tool translation and validation utilized a methodological approach. The study utilized 21 participants with mild to moderate aphasia of different etiologies using convenience sampling from different Speech Therapy Clinics and Riphah Rehabilitation Clinic, Lahore, Pakistan from July 2021 to October 2021. The process included forward translation, reconciliation, backward translation, review and Pre-testing by a panel of experts. The validation of Urdu-CCRSA was conducted by five experts. CVR, I-CVI & S-CVI & Cronbach alpha coefficient were calculated, and the tool was piloted for test and test-retest reliability. SPSS version 21 was utilized for data analysis.
Results: The Urdu CCRS revealed Convent Validity Ratio of >0.6, while Content validity index for individual items (I-CVI) >0.70 for all items and for the whole scale (S-CVI/ Average) was >0.88 (Relevance=0.88, Clarity=0.87, Simplicity=0.88 and Ambiguity=0.88), indicating very good content validity. Cronbach's alpha reliability coefficient was 0.972 for the total scale, while it was >0.765 for all individual items, indicates a high level of internal consistency. While Test and Re-Test reliability revealed a correlation coefficient value of 0.987 (0.977-0.994).
Conclusion: The CSRSA in the Urdu language is a valid and reliable tool with acceptable test–retest reliability, internal consistency, and construct validity to measure the communication confidence of the patients with aphasia, who can speak and understand Urdu.

Key words: Aphasia, Communication Confidence Rating Scale for Aphasia, reliability, translation, validation.
