背　景 產後婦女常經歷性問題及夫妻間的親密關係改變。
目　的 本研究旨在探討產婦性健康自我效能之相關因素，並進一步預測其重要因子。
方　法 採橫斷式問卷調查，以立意取樣的方式選取北部某醫學中心及區域醫院之產婦進行研究，共計301位產婦參與研究。
結　果 大多數產婦之性健康自我效能具有「中度」的水平。基本屬性中以年齡、生產方式、哺餵方式、自然流產等為影響產婦性健康自我效能的因素。運用複迴歸法分析產婦性健康自我效能之預測因子，結果顯示年齡與哺餵方式可以預測產婦性健康自我效能，共可解釋7%變異量。亦即年齡介於26－44歲者及母乳哺餵者其產後性健康自我效能愈好。
結　論／實務應用 本研究結果可作為醫護人員之參考，並建議醫護人員可提供促進18－25歲產婦性健康自我效能之策略，以增進其性健康，並鼓勵產婦哺餵母乳除了能增進親子依附關係之外，亦能增進夫妻間的性親密及性滿意度。

Background: Parturients often experience changes in intimate relationships.
Purpose: The purpose of this study was to investigate the correlates and predictors of Sexual Health Self-Efficacy among Postpartum Women (SHSE-P).
Methods: A total of 301 participants from the postpartum ward of a medical center and regional hospital in northern Taiwan were recruited through purposive sampling.
Results: Results showed that most participants fell into the “moderate” range of sexual health self-efficacy. Age, mode of delivery, breastfeeding, and spontaneous abortion were contributing factors to participant sexual health self-efficacy. Multiple regression showed age and breastfeeding to be significant predictors of SHSE-P, explaining 7% of variance among participants. Breastfeeding women between 26 and 44 years of age had better postnatal sexual health self-efficacy.
Conclusion / Implications for Practice: Intervention to prevent the continuance and/or exacerbation of sexual difficulties in parturients in the 18-25 years of age range is necessary. Promoting proper breastfeeding may not only enhance the positive relationship between parents and children, but also improve the level of satisfaction enjoyed in couples’ intimate relationships.
