    Abstract Background Health professionals and healthcare volunteers play a critical role in promoting uptake of the fecal occult blood test (FOBT), which is an effective screening method for colorectal cancer. However, previous studies paid less attention to investigating both groups regarding their intention to undergo the test. This study used the Health Belief Model (HBM) to explore the likelihood of an FOBT uptake among health professionals and healthcare volunteers aged 50 years or older. Methods A cross-sectional survey was conducted at public health centers in a county in northern Taiwan. Health professionals and healthcare volunteers were invited to complete the questionnaires. Overall, 391 valid questionnaires were obtained (response rate = 93.10%). Structural equation modeling was used to examine the associations among the variables based on the HBM. Results The HBM explained 45, 44, and 50% of the variance in the likelihood of undergoing an FOBT in all participants, health professionals, and healthcare volunteers, respectively. The explained variance in healthcare volunteers outweighed that of professionals by 6%. Perceived benefits and self-efficacy significantly affected the likelihood of undergoing an FOBT. Self-efficacy significantly mediated the effects of perceived severity, benefits, and barriers on the likelihood of an FOBT uptake. A borderline significant difference in structural coefficients was found across groups. Conclusions The HBM model was used to examine the likelihood of an FOBT uptake among health professionals and healthcare volunteers, and the results showed that self-efficacy was the optimal predictor of the likelihood of an FOBT uptake, followed by perceived benefits. Future multifactorial interventions to promote FOBT uptake among health professionals and healthcare volunteers aged 50–75 years could include these significant factors.

    運用健康信念模式探討衛生保健志工及專業人員的糞便潛血檢查行為之可能性及其相關因素
    (2016) 莊淑姿; Chuang, Shu-Tzu
    目的：台灣地區大腸直腸癌發生率隨之增加，且為發生人數增加最多 之癌症，本研究採用健康信念模式為理論基礎，探討其各信念與癌症防治工作人員採取糞便潛血檢查行為之關係及其他相關因素。方法：採立意取樣，以衛生保健志工及衛生保健專業人員為對象，介於50-74歲之間，以結構式問卷為研究工具，共發出420份，得有效問卷401份(95.48%)。結果：衛生保健專業人員在大腸直腸癌篩檢知識、自覺罹患性、自覺行動利益及採取糞便潛血檢查行為可能性之得分顯著高於衛生保健志工；複迴歸分析顯示，自覺行動利益、自我效能為採取糞便潛血檢查行為可能性之顯著預測因子，在解釋變異量上，衛生保健志工為48%，衛生保健專業人員為43%。結論：健康信念模式相當適合用於採取糞便潛血檢查行為可能性，特別是自覺行動利益、自我效能，對於衛生保健志工與衛生保健專業人員接受糞便潛血檢查行為之可能性具顯著影響力，建議未來教育介入針對自覺行動利益與自我效能等兩個重要因子進行改善。
