Abstract

This quasi-experimental study aimed to test the effect of self-breast massage program on milk ejection of first-time mothers. The sample consisted of 50 first-time mothers who were receiving antenatal, intrapartum, and postpartum care at a community hospital. Purposive sampling was used to recruit the mothers, who were then assigned to an experimental group (n = 25) or a control group (n = 25). The control group received standard care, while the experimental group received the self-breast massage program. The research instrument consisted of (1) the self-breast massage program; (2) the data-collecting instruments: a personal data form and milk ejection assessment form; and (3) the experimental-control instruments: a record of self-breast massage in the postpartum period. The tools were approved by three experts, yielding a content validity index of .80. The reliability of the milk ejection assessment form was examined using interrater of reliability, yielding a value of 90. Data were analyzed using frequency, percent, average, standard deviation, chi-square, independent t-test, Friedman and Kruskal Wallis test. The results of the study were as follows. First-time mothers who received the self-breast massage program had mean scores of milk ejection after intervention at 4, 12, 24, and 48 hours significantly higher than the control group (X = 4.99, p < .05), (X = 14.05, p < .001), (X=7.23, p<.01), and (X = 20.85, p < .001), respectively. The result showed that the self-breast massage program increases milk ejection. Thus, nurses should apply the self-breast massage program to promote breastfeeding of first-time mothers.
