Therefore, a time-efficient and valid screening tool is required. This study aimed to culturally adapt and validate the self-reporting questionnaire-20 tool developed by the World Health Organization among pregnant mothers in Ethiopia.Methods: A total of 310 pregnant women completed the questionnaire at two selected health centers in the regional state of Amhara. The World Health Organization’s Self Reporting Questionnaire-20 tool was first translated into Amharic by two experts. The back translation was done by two English experts. Internal consistency and reliability were assessed using Cronbach’s alpha. Convergent and discriminant validity were assessed using composite reliability and extracted mean variance. SRQ-20 was tested for reliability and validity using principal components analysis and the Kaiser-Meyer-Olkin measure of sample adequacy with a cutoff value of 0.50 for each item.Results: The Kaiser-Meyer-Olkin measure (KMO = 0.733) for sample adequacy and the Bartlett’s sphericity test for the identity matrix indicated that the data were amenable to exploratory factor analysis. Principal components analysis identified six factors that explained 64% of the variation in the self-report questionnaire 20. Cronbach’s alpha was 0.817 for the entire scale and the extracted mean variance was greater than 0.5 for all factors, indicating convergent validity. The extracted mean variance, composite reliability, and factor loadings were all greater than 0.75 for all factors in this study, indicating that convergent validity was satisfactory and that discriminatory validity was also satisfied. The composite factor reliability scores ranged from 0.74 to 0.84, and the square roots of the mean variances were greater than the factor correlation scores.Conclusion: The interview-based, culturally-adapted 20-item Amharic version of the SRQ-20 tool demonstrated good cultural adaptation and was also found to be valid and reliable in the present context.Keywords: antenatal common mental disorders, cultural adaptation, factor analysis, SRQ-20, Ethiopia
