The Effect of Breastfeeding Education Given to Family Members Who Support the Mother in the Postpartum Period on Breastfeeding Parameters. Istanbul University-Cerrahpaşa Graduate Education Institute, Midwifery Department. Doctoral Thesis. Istanbul.

I To examine the effect of breastfeeding education given to family members in the postpartum period on breastfeeding parameters. It was conducted as a randomized controlled experimental study to determine the effect of breastfeeding education given to the family member who supports the mother in the postpartum period on breastfeeding parameters

Power analysis was performed using the G*Power(v3.1.9) program to determine the sample size. The power of the study is expressed as 1-β (β = probability of type II error) and in general, studies must have 80% power. According to the effect size coefficients determined by Cohen, assuming that the evaluations to be made between two independent groups will have a medium effect size (d = 0.5), α = 0.05 and β = 0.20, it was determined that there should be at least 64 people in each group, according to the calculation. Considering that there may be losses during the study process, the sample size was increased by 20% and it was decided to include at least 77 people in each group. The calculation of the sample size was based on Zeliha Burcu Baysal's doctoral thesis titled The Effect of Breastfeeding Education and Counseling Given to Pregnant Women and Their Spouses on the Breastfeeding Process and Attachment.

The main aims of the study are:

Breastfeeding education given to the family member; Does it increase the rate of mothers starting breastfeeding? Breastfeeding education given to the family member; Does it increase the rate of mothers giving exclusive breastfeeding in the first month? In the intervention group, family members will be given breastfeeding education and they will be asked to support mothers in the postpartum period.

In the comparison group, no breastfeeding education was given to the family member.
