Women's breastfeeding self-efficacy during pregnancy were evaluated with the Breastfeeding Self-efficacy Scale.

This scale was developed by Dennis et al (2003) for fear after childbirth. The Turkish validity and reliability of the scale were performed by Tokat et al. (2010). This scale consisting of 14 items is a 5-point Likert-type. The positive-meaning items are scored in reverse order. Therefore, the scores ranged from 14 to 70. The scale has no cutoff score, and high scores indicated higher breastfeedin self- efficacy.

There are two versions of the scale used during pregnancy and postpartum. In both versions, the items are the same and the tenses change. In order to evaluate the Turkish validity and reliability of both antenatal and postnatal versions of the scale, language, structure and predictive validity analyzes were performed and the Cronbach's alpha value was found to be 0.87 for the antenatal measurement tool and 0.86 for the postnatal measurement tool.
