Abstract | Objective: This study aims to is to develop a disorder-specific patient-reported outcome measure to be used in Islamic clergymen with voice disorders and to investigate its validity and reliability. Methods and procedures: Employing an exploratory sequential mixed-methods design, this study conducted in two phases. Initially, semistructured interviews were conducted with 10 clergymen experiencing voice disorders. Subsequently, the questionnaire underwent rigorous validation, encompassing content, construct, and criterion validity assessments, in addition to test-retest reliability and internal consistency analyses. The index was administered to a sample of 110 male clergy, including imams, muezzins, and Quran course teachers, with an age range from 19 to 61years. Results: Construct validity was established through factor analysis, resulting in a final 23-item scale categorized into two factors: physical-functional and emotional. Known group validity demonstrated a significant distinction between the study and control groups. Criterion validity reinforced the index's validity, displaying a correlation coefficient of 0.758 between the Voice Handicap Index for Clergymen and the well-established Voice Handicap Index. The questionnaire exhibited commendable internal consistency, with a Cronbach's Alpha (α) coefficient value of 0.971. Test-retest reliability analysis exhibited strong consistency, with a Pearson correlation coefficient of 0.863. Conclusions: It is recommended that the developed valid and reliable handicap index in the present study be included in the voice assessment batteries of Islamic clergymen with voice complaints with the clinical and research purposes. In future studies, the validity of the questionnaire can be investigated more by examining the difference between the Voice Handicap Index for Islamic Clergymen (CVHI) scores obtained before and after treatment. Identifying a cut-off point that discriminates between dysphonic and normophonic clergymen may allow the use of the CVHI as a screening tool for this population. |
