本研究旨以健康信念模式探討某醫學中心女性醫事人員執行乳癌篩檢行為及影響因素。採結構式問卷以北部某醫學中心之女性醫事人員為研究對象，收案期間2007年10月1日至31日，以立意取樣，共獲得384份有效問卷（完整問卷回收率51.6%）。研究對象平均年齡37±8.9歲，32%（121位）會定期進行乳房自我檢查，12%會定期接受乳房攝影檢查，僅10%會定期進行臨床醫師檢查。乳癌罹患性認知、乳房自我檢查自我效能、宗教、停經年齡、有乳房疾病史能預測女性醫事人員執行乳房自我檢查(R^2=.142)；自覺乳房篩檢之行動利益、工作年資及乳房疾病史，則可預測接受乳房攝影檢查之行為(R^2=.225)。健康促進單位宜加強提升女性醫事人員乳房自我檢查自我效能，及行動利益之策略運用，以提升女性醫事人員乳癌篩檢之執行率。

The purpose of this study was to explore female medical personnel behaviors toward breast cancer screening and its influencing factors based on health belief model. Structured questionnaire was used with purposive sampling, and subjects were recruited from a Taipei medical center in October 2007. The total sample size was 384 (complete rate of 51.6%). The results were as follows: Average age of subjects was 37±8.9 years old. 121 (32%) subjects performed breast self-examination (BSE) regularly, 12%hadmammography and 10% received physician clinical examination as recommended. Awareness of breast cancer susceptibility, self-efficacy of BSE, religion, age of menopause, and history of breast disease were factors to predict BSE performance by subjects (R^2=.142); Subjects perceived benefits in breast cancer screening while working years and history of breast disease could predict the decision to choose mammography (R^2=.225). According to research findings, we recommend that in order to improve breast cancer screening rate, health promotion agency should enhance BSE self-efficacy and understand the benefits involved in breast cancer screenings.
