  1. aANCOVA Test controlled such variables as willingness to pregnancy, level of mother’s education, and wife’s level of education
  2. b Breastfeeding self-efficacy has 33 items and is scored on Likert spectrum with score 1 for “totally disagree” to score 5 for “totally agree”. The distance between scores is from 33 to 165, and higher scores indicate a higher level of self-efficacy in breastfeeding
