The study was planned to provide knowledge and skills regarding breast milk and breastfeeding to midwifery students who will provide breast milk and breastfeeding consultancy to women and the society during pregnancy, birth and postpartum period after graduation, and to positively develop their professional affiliation and perception of the profession.

In this context, the following hypotheses will be tested in the study:

H0: Breastfeeding support education has no effect on the professional affiliation and perception of the profession of intern midwifery students.

H1: Breastfeeding support education increases the breastfeeding and breast milk knowledge and skills of intern midwifery students.

H2: Breastfeeding support education increases the professional affiliation of intern midwifery students.

H3: Breastfeeding support education positively develops the professional perception of intern midwifery students

The universe of the study will consist of all students studying in the Department of Midwifery at SAU Faculty of Health Sciences, and the sample will consist of senior midwifery students. In order to determine the sample size, a power analysis will be conducted using the G*Power (v3.1.7) program. The aim of the study was to evaluate the differences in the mean knowledge level scores between the groups. The effect width value was taken as 0.70 as the method used in cases where it is not known how many units of difference are significant between the groups. The effect width value of 0.20 is very high, 0.50 is at a medium level, and 0.80 gives results under the maximum acceptance limit. As the power of the study increases, it means that the measurement is more sensitive in finding the difference. The power is expected to be 0.80 and above. In the case of a Type 1 error probability (α) of 0.05 (95% confidence interval), a power level of 80%, and an effect width value of 0.70, the study will be planned with a total of 68 students, 34 students for each group. Considering the possibility of data collection forms being incomplete and empty, 10% of the sample size (37 for each group, totaling 74 students who meet the inclusion criteria) will be included in the study. When the desired number is reached for each group during the study process, the power of the study will be calculated again (post hoc).
