Abstract

Aim: This study aims to conduct reliability and validity study of the Turkish version of the "Prenatal Breastfeeding Self-Efficacy Scale", which determines pregnant women's perception of breastfeeding self-efficacy in the prenatal period.

Material and method: This methodological research was carried out between December 2014 and May 2016 in maternity clinics of the Erzurum Nene Hatun Maternity Hospital and Atatürk University Research Hospital. The study population consisted of pregnant women, admitted to the specified clinics for prenatal controls. The study was carried out with 326 pregnant women, who met the inclusion criteria and agreed to participate in the research without any sample selection. "Personal Information Form" and "Prenatal Breastfeeding Self-Efficacy Scale - Turkish Form" were used for data collection. The data were collected by the face-to-face interview method, and analyzed by SPSS 18 software. In the validity-reliability analysis of the scale, language and content validity, explanatory factor analysis, Cronbach's Alpha coefficient, item-total score correlation, and testretest methods were used.

Results: Linguistic validity was verified by the translation-backtranslation of the Prenatal Breastfeeding Self-Efficacy Scale, then the necessary corrections were made according to the recommendations of the expert opinions, to ensure the content validity. As a result of the explanatory factor analysis, performed to determine the construct validity of the scale, a single factor structure was found, having factor loadings in the appropriate range (0.30-0.76). In the internal consistency analysis of the scale, Cronbach's Alpha was 0.86, and the item-total score correlations were between 0.23 and 0.65, and no item was removed from the scale. In order to test the time-invariance of the scale, the test-retest correlation value was found to be 0.94. The relationship between the two applications were determined to be statistically significant (p < 0.001).

Conclusion: Turkish version of the Prenatal Breastfeeding Self-Efficacy Scale was evaluated in Turkish women and found to be a valid and reliable measurement instrument.
