接受愛滋病個案管理之男同志保險套使用行為意圖及重要解釋因子探討

Factors Associated with Intention to Use Condoms among MSM Receiving HIV Case Management

台灣推動「愛滋病個案管理計畫」，希望藉此降低感染者危險性行為，但每年新感染人數仍有約2,200人，故了解接受愛滋病個管之感染者對於保險套使用行為意圖，是目前愛滋病防治的重要議題。本研究應用「計畫行為理論」探討接受愛滋病個案管理之男同志保險套使用行為意圖及重要解釋因子。本研究為橫斷性研究，以結構式問卷為評量方式，並依研究對象之特殊性進行部分修改，Content Validity Index （CVI）值在.84至.98間。在南部某醫學中心選取加入「愛滋個管計畫」連續追蹤管理2次以上，且規律回診者，共完成203份問卷，完成率為94.8％。研究結果發現「知覺行為控制」、「主觀規範」是男同志於口交或肛交保險套使用行為意圖的重要解釋因子，可提供臨床照顧及政府政策規劃參考。

Despite an HIV case management plan aimed at reducing risk behavior in people living with HIV in Taiwan, about 2,200 new infections occur every year. Therefore, the factors associated with the intention to use condoms in individuals who are HIV positive and receiving HIV case management are important issues in HIV/AIDS prevention. We used the theory of planned behavior to investigate the intention to use condoms and factors associated with these intentions among MSM receiving HIV case management. Our study used a cross-sectional design and a structured questionnaire as the measurement instrument. We used the questionnaire developed by Huang (2008), with some partial modifications based on the characteristics of our study participants. The Content Validity Index (CVI) of the four scales as assessed by experts ranged from 0.84 to 0.98. We used purposive sampling to select participants who had been followed-up at least twice as part of the HIV case management program in a medical center in southern Taiwan. A total of 203 respondents completed the questionnaire (completion rate of 94.8%). We found that the main explanatory factors associated with the intention to use condoms among MSM during oral and anal sex were perceived behavioral control and subjective norms. These findings can be used to inform clinical care and government policy.
