INTRODUCTION: The aim of the study is to define the validity and reliability of the Turkish version of postpartum hemorrhage-specific self-efficacy scale.
METHODS: The study was conducted in methodological type. The sample of the study consisted of 238 physicians, nurses, and midwives, working in the delivery room, postnatal, and birth emergency areas for at least 2 years. The data were collected by introductory information form, generalized self-efficacy scale, and postpartum hemorrhage-specific self-efficacy scale in February-December 2018. The structural validity of the scale was evaluated by exploratory factor analysis. In the context of reliability analyses, Cronbach’s alpha, the item-total score correlation and the parallel test methods were used.
RESULTS: According to the factor analysis results, it was found that the two-factor structure explained 69.38% of total variance and that item loads ranged between 0.31 and 0.88. Item total score correlations were found to be between 0.42 and 0.77. Cronbach’s alpha value was 0.92 for the whole scale. Positive and middle level correlation was found between both scales as a result of parallel testing (r=0.301; p=0.000). It was determined that the self-efficacy sub-dimension of the scale consisted of eight items and the collective efficacy sub-dimension of 13 items, and a total of 21 items. Fit indices were found to be at an acceptable level as a result of the confirmatory factor analysis (χ2/df=3.08, RMSEA=0.09, GFI=0.91, AGFI=0.77, IFI=0.92, CFI=0.92, NFI=0.89, RFI=0.87).
DISCUSSION AND CONCLUSION: The Turkish version of the Postpartum Hemorrhage-Specific Self-Efficacy Scale was found valid and reliable. The scale can be used to evaluate physicians, nurses, and midwives’ self-efficacy perception specific to postpartum hemorrhage.
