本研究目的在探討已婚婦女安全性行為執行情形及其相關因素。針對高雄市20-49歲已婚婦女，由民政局所提供的資料採系統隨機抽樣方式，抽出600位已婚婦女，自2002年9月至2003年2月經郵寄方式，以無記名自填式結構問卷進行資料收集，共回收有效問卷為205份。研究結果顯示：(1)．已婚婦女安全性行為得分指標為58，與國外文獻比較，顯得偏低。(2)．年齡愈大執行安全性行為愈差。教育程度愈高執行安全性行為愈好。(3)．愛滋病知識得分越高，其安全性行為得分亦高。(4)．保險套使用自我效能與安全性行為無顯著相關，而性自我效能得分越佳，執行安全性行為越好。(5)．關係控制因素與安全性行為無顯著相關，但在決策支配得分愈高者執行安全性行為越好。(6)．愛滋病知識及性自我效能為安全性行為的顯著預測因子，可解釋安全性行為44.9%之總變異量。根據本研究的結果，可作為將來針對已婚婦女愛滋病衛生教育之參考，及提供未來研究方向之建議。

The purpose of this study is to explore safe sex behavior and related factor(s) in married women. Samples were randomly selected from a database center at the Department of Civil Services of the City of Kaohsiung. 600 married women aged 20 to 49 years old were randomly selected, and 205 valid questionnaires were completed. The findings of this study were as follow: (1) The index score for safe sex practice among married women was 58, which was lower than that of most foreign countries; (2) Older women had lower safe sex practice scores than younger women. Married women with higher education level had higher safe practice scores; (3) Married women with higher scores for AIDS knowledge also earned higher scores for safe sex practice; (4) There was no significant relationship between condom use self-efficacy and safe sex practice. However, better safe sex practices were found among married women who had higher sexual self-efficacy scores; (5) There was no significant relationship between relationship control factor and safe sex practices. Married women who had higher decision making scores had better safe sex practices; (6) The most important predictors for safe sex practice were AIDS knowledge and sexual self-efficacy, which accounted for 44.9% of total variance for safe sex practices. The findings of this study can be used as a reference for further research in the field of health education in AIDS prevention for married women.
