目標：本文是探討軍人與主要性伴侶性交時使用保險套的意向。方法：受訪者是在臺灣某一個軍營中，徵得751位軍人同意參加研究，本文是分析其中518位單身且有性經驗者對於保險套使用的負面態度、主觀規範、冒險及保險套知覺行為控制、與將來六個月內性交時使用保險套意向。資料分析是採用驗證式因素分析 (CFA) 與結構方程模式 (SEM) 。結果：研究結果顯示，以CFA測量模式發現測量題項能適切地組成三個潛在變項：保險套使用的負面態度 (4個項目)、主觀規範 (4個項目)、與冒險及保險套知覺行為控制 (3個項目)。SEM分析結果顯示保險套使用的負面態度、主觀規範、冒險及保險套知覺行為控制有顯著的路徑指向未來使用保險套的意向。整體模式結果指出計畫行為理論能解釋未來保險套使用意向38%變異量。結論：本研究結果提供軍人在保險套的使用是受到多元因素彼此互相影響的證據，藉由瞭解這些因素對於男性在使用保險套的影響，可以協助提高保險套使用以及降低性傳染疾病 (包含愛滋病) 傳染可能性。

Objectives: The purpose of this study was to examine the intention to use condoms among single and sexually active male conscripts in Taiwan.Methods: The study subjects were 751 conscripts who signed consent forms at a military camp. They self-administered a survey questionnaire regarding their attitudes, subjective norms, adventure and perceived control of using condoms, as well as their intention to use condoms during sex in the next 6 months. Confirmatory factor analysis and a structural equation model were applied.Results: Data from 518 single and sexually active participants were analyzed. The measurement model of attitudes toward condom use (4 items), subjective norms (4 items), and adventure and perceived behavior control (3 items) fit the data well (χ2(38)=47.8, p=0.13; CFI=0.99; RMSEA=0.02). The final structural equation model showed significant paths from latent constructs of negative attitudes about condom use (β=-0.47), subjective norms (β=0.36), and adventure and perceived control of condom use (β=-0.48) to the intention of using condoms in the next 6 months. In addition, constructs of the theory of planned behavior accounted for 38% of the variance of intention to use condoms.Conclusions: Understanding how conscripts respond to condom use in the context of identifying multiple pathways to safer sex for men can increase condom use and reduce the incidence of sexually transmitted diseases, including AIDS.
