Standardization of an Arabic Version of the Overall Assessment of the Speaker’s Experience of Stuttering for Adults OASES-A-A

Abstract Background: Stuttering is a multifaceted disorder that needs comprehensive assessment. Aim of Study: This study aims to provide a standardized Arabic version of the OASES-A questionnaire in order to meet the need for comprehensive evaluation of stuttering. Material and Methods: The original English version of the OAESE-A was translated into Arabic using forward and backward translation, and was administered to 133 adult participants together with Arabic stuttering severity instrument (ASSI). Reliability was measured by internal consistency reliability and test retest reliability. Seventy-six participants were subjected to retest after 1-3 weeks interval to measure reliability. Convergent validity was measured by the correlation between the test items and the AS SI. Results: One hundred thirty three person who stutter participated (PWS) in this study, 83 male and 50 female, with mean age of 28.4 years (range of 18 to 51 years). OASES-A-A showed high internal consistency (Cronbach’s alpha >0.80), and a good test-retest reliability (r=0.88-1.00). Construct validity was confirmed by the positive correlation between the test items and the ASSI. Conclusion: Arabic OASES-A has demonstrated a high degree of reliability and validity.
