Validation of an instrument assessing certified nurse-midwives' attitudes toward breastsleeping.

To date, attitudes toward breastsleeping among certified nurse-midwives caring for postpartum women are not well known. This study describes the validation procedures of two instruments assessing the attitudes of certified nurse-midwives toward breastsleeping. These tools were validated using an 18-item survey administered to a convenience sample of certified nurse-midwives. Participating certified nurse-midwives were recruited for anonymous participation in an online survey in September-November 2019. Factor analysis and parallel analysis each revealed a two-factor solution, suggesting that there were two main concepts representing the attitudes of certified nurse-midwives toward breastsleeping: breastsleeping safety and breastfeeding experience. Statistically significant differences for mean breastsleeping safety scores were noted by age group, place of practice, and United States' geographical region.
