Abstract

Background: Iranian researchers have investigated breastfeeding self-efficacy and its related factors. However, there is no valid and reliable tool for assessing the breastfeeding self-efficacy of Iranian Farsi-speaking women. Research aim: To examine the validity and reliability of the Breastfeeding Self-Efficacy Scale—Short Form among Iranian Farsi-speaking mothers. Methods: We conducted this cross-sectional study at Izadi teaching hospital in Qom, Iran. Using convenience sampling, we recruited 174 mothers, who completed the questionnaire on the first postnatal day. A forward–backward translation method was used to translate the scale. Cronbach’s alpha and item-total characteristics were examined to test reliability. Construct validity was evaluated via principal component analysis (PCA), as well as known-groups validity. Results: The mean (standard deviation) of sample age was 28.33 (5.38). The mean (standard deviation) of breastfeeding self-efficacy score was 54.32 (10.50), ranging from 24–70. Cronbach’s alpha (.92), inter-item correlations (.21–.72), and corrected item-total correlations (.44–.75) indicated the adequate reliability of the scale. PCA yielded one component with an eigenvalue of 6.97, explaining 49.8% of the total variance. There was no significant difference in the self-efficacy scores between primiparous and multiparous women. Breastfeeding self-efficacy was not significantly different between the groups in terms of the demographic characteristics. Conclusion: The Farsi version of the Breastfeeding Self-efficacy Scale—Short Form is a valid and reliable instrument for Iranian Farsi-speaking mothers, with sound psychometric properties per the other studies worldwide. © The Author(s) 2019.
