Aim: This study aimed to evaluate the validity and reliability of the Turkish version of the Contraceptive Self-Efficacy in Women in Sub-Saharan Africa (CSESSA) scale. Background: Contraceptive self-efficacy is a crucial predictor of utilization of modern contraceptive methods. However, the existing tools for comprehensively assessing contraceptive self-efficacy are limited. Methods: The sample of this methodological study consisted of 510 female participants of reproductive age. The translation and cultural adaptation of the scale were performed. For validity, content validity and construct validity were tested. For reliability, test-retest reliability, Cronbach's alpha coefficient, and item-total score correlations were evaluated. Findings: The goodness-of-fit indices showed an overall acceptable fit with the three-factor model. Cronbach's alpha for the overall CSESSA scale was 0.867, and for the three subscales, it ranged from 0.77 to 0.84. The scale's test-retest reliability was found to be r = 0.83 (p < 0.001), and the item-total correlations score ranged from 0.495 to 0.646. The Turkish version of the scale is a valid and reliable tool to measure the contraceptive self-efficacy of women of reproductive age. This scale can provide a comprehensive understanding of self-efficacy by assessing various dimensions of contraceptive self-efficacy.
