Objective: The aim of this study was to develop a valid and reliable measurement tool that can be used to assess health professionals’ self-efficacy in electronic fetal monitoring (EFM) interpretation and management. Methods: Between August and December 2022, 283 midwives and nurses working in a private hospital group in Istanbul, familiar with the use and interpretation of the EFM device, and working in the field of obstetrics and gynecology for at least 6 months were included in the study. Internal consistency and item analyses were used to examine the content, construct validity, and reliability of the EFM monitoring self-efficacy scale. Within the scope of validity analyses for the development of the scale, (1) content validity with expert opinions and the Davis technique, (2) construct validity with the Kaiser–Meyer–Olkin coefficient, the Barlett sphericity test, and explanatory factor analysis were analyzed. Within the scope of reliability analyses, (1) internal consistency with Cronbach’s alpha reliability coefficient and item total statistics and (2) comparisons of lower and upper groups were analyzed. Results: The Turkish adaptation of the scale was carried out with language and content validity, construct validity, and reliability analyses. The content validity index was found to be 0.97 after 5 items with a content validity index below 0.78 were removed in line with the expert opinions on the 37 items in the scale. As a result of the exploratory factor analysis of the scale, it was determined that it showed a 1-dimensional structure with 32 items explaining 77.59% of the total variance. In the confirmatory factor analysis of the 1-dimensional scale, it was seen that the model had an acceptable fit. In the reliability analysis of the scale, it was determined that the Cronbach-alpha internal consistency coefficient was 0.98 and the test–retest reliability coefficient was 0.80. Conclusion: Validity and reliability analyzes showed that the scale was acceptable in terms of structural features and internal consistency.
