Data instruments
This study’s measures included socio-demographic and obstetrics questionnaires, the Rosenberg self-esteem scale, the Multidimensional Body–Self Relations Questionnaire, and an exclusive breastfeeding questionnaire. Socio-demographic and obstetric questionnaires were completed prior to the study, and the Rosenberg self-esteem scale and Multidimensional Body–Self Relations Questionnaire were completed by both groups before the intervention, immediately after the completion of the intervention sessions, and then 4 weeks after childbirth. Similarly, one month after childbirth, a breastfeeding questionnaire was completed via interview.
