研究背景：2010年國民健康署對國民純母乳哺餵率的調查結果顯示，國人產後一個月至產後四個月的純母乳哺餵率有下降的趨勢。國外學者研究指出，母乳支持團體提供的專業協助與同儕支持可增強產婦的哺乳意願並延長產婦的哺乳時間，且該效果在生產後三個月內最為有效。
研究目的：本研究旨在了解：(1)產婦參加母乳支持團體後對母乳哺餵自我效能的提升狀況；(2)產婦參加母乳支持團體後對母乳哺餵持續時間的提升狀況。
研究方法：研究樣本為102位產婦，包含為產後二個月及三個月有參加母乳支持團體之實驗組，及為產後二個月及三個月無參加母乳支持團體之對照組。研究方法為研究問卷，問卷包含個人基本資料及母乳哺餵自我效能簡式量表等，並對蒐集所得資料進行敘述性統計、重複測量及線性迴歸等分析。
研究結果：實驗組母乳哺餵效能、哺乳意願皆較對照組高。在產後兩個月及產後三個月兩個時點，實驗組在技術層面與個人認知層面皆展現較高的自信，且預計持續哺育的時間較長。參加支持團體次數對產後住院期間母乳哺餵的自我效能及預計持續哺育時間亦有正面影響。
結論：研究顯示參加母乳支持團體之產婦的哺乳意願及哺餵自我效能皆有較高的表現，故孕期參與母乳支持團體對產婦於產後哺餵母乳有正面幫助。

Research Background: Breastfeeding rate is declining after the first to 4th months. Scholars suggested breastfeeding support groups combine professional peer support, may enhance mother’s motives and prolong breastfeeding duration.
Research Purpose: Understand the effects of support group to breastfeeding self-efficacy and intended feeding duration.
Research Methodology: Mothers were diided into the experimental and control groups. Women participated in the breastfeeding support group were considered as the experimental group. A structured questionnaire research tool was used for data collection. Repeated measures and linear regression were adopted to analyze the data.
Research Results: The sample consists of 102 lying-in women. Women in experimental group reveal higher breastfeeding self-efficacy and higher breastfeeding willingness both in the second and third postpartum month. Women in the experimental group demonstrated higher self-confidence in breastfeeding techniques and interpersonal thoughts. In addition, women also extended their intended breastfeeding duration. Furthermore, times of attending breastfeeding support groups contributes to higher breastfeeding self-efficacy.
Conclusion: The above results indicate that attending breastfeeding support groups improves mothers’ breastfeeding self-efficacy and breastfeeding duration. As a result, this study indicated that attending breastfeeding support groups has a positive impact on breastfeeding.
