探討產後婦女之母乳哺餵自我效能與哺乳意圖對母乳哺餵行為的影響

本研究旨在探討產後婦女之母乳哺餵自我效能與哺乳意圖對產後六個月純母乳哺餵行為的影響，並建立哺乳意圖量表中文版的信效度，採縱貫式研究設計，立意取樣於南部某區域教學醫院之產後病房母乳哺餵的產婦，於2016年3月至2016年9月共計收取167位研究對象，使用結構式問卷與電話訪問收集研究資料，包含人口學資料調查表、母乳哺餵自我效能簡式量表中文版、哺乳意圖量表中文版及母乳哺餵行為，所得資料以SPSS 18.0、LISREL8.7及S-Plus套裝軟體進行描述性統計、獨立樣本t檢定、皮爾森積差相關係數、單因子變異數分析、存活分析及信效度檢定。研究結果發現本研究對象的母乳哺餵自我效能平均總分為44.80(±11.56)分，哺乳意圖平均總分為12.20(±3.14)分，產後第六個月的純母乳哺餵率為29.9%。研究對象的母乳哺餵自我效能與哺乳意圖具有顯著正相關(r=.45, p<.001)，母乳哺餵自我效能(p=.03)與哺乳意圖(p<.001)是產後六個月純母乳哺餵行為的影響因子。教育程度(p<.01)、職業(p<.01)及哺乳意圖(p<.001)是產後六個月純母乳哺餵行為的預測因子。哺乳意圖量表中文版之Cronbach’s alpha係數為0.77，具備良好構念效度。本研究結果可作為爾後學者探討產婦母乳哺餵自我效能、哺乳意圖及母乳哺餵行為之參考。

This study aims to explore the influence of breastfeeding self-efficacy and breastfeeding intention on exclusive breastfeeding behavior six months postpartum among postpartum Women, and establish the reliability and validity of the Chinese version infant feeding intentions scale. In longitudinal research, the research attempts to collect samples of breastfeeding mothers at postpartum wards in the teaching hospital in the certain district of Southern Taiwan. The total of 167 subjects were collected between March 2016 and September 2016. The research data collected through structure questionnaire and telephone interviews include demographic survey , breastfeeding self-efficacy scale-short form Chinese version, infant feeding intentions scale Chinese version and breastfeeding behavior. The descriptive statistics, independent sample t test, Pearson product-moment correlation coefficient, survival analysis, and reliability and validity test of the collected breastfeeding data through SPSS 18.0 , LISREL8.7 and S-Plus package software. The result of the study shows that the average total score of breastfeeding self-efficacy of the objects of study is 44.80(±11.56) while the average total score of breastfeeding intention is 12.20(±3.14), and exclusive breastfeeding rate of six months postpartum is 29.9%. The breastfeeding self-efficacy of the objects of study and breastfeeding intention are significantly in positive correlation(r=.45, p<.001). Breastfeeding self-efficacy (p=.03) and breastfeeding intention (p<.001) have significant influence on exclusive breastfeeding after six months postpartum. Education level (p<.01), occupation (p<.01), and breastfeeding intention (p<.001) are predictive factors of exclusive breastfeeding after 6 months postpartum. The Cronbach’s alpha coefficient in infant feeding intentions scale Chinese version is 0.77, and with good construct validity. The results of the study can serve as the reference for future academic exploration of breastfeeding self-efficacy, breastfeeding intention, and breastfeeding behavior.
