目的：本研究是探討曾使用俱樂部藥物之高關懷青少年採用較安全性行為的意向。方法：研究對象為全臺灣矯正機構之青少年，採用計畫行為理論，加上原型／意願(Prototype/Willingness)兩個變項為研究架構。依據回顧文獻編製結構性問卷，包含愛滋病知識、主觀規範、使用保險套之態度、保險套使用行為之知覺行為控制、保險套使用之原型、保險套使用之意願、與未來使用保險套行為的意向。問卷題目由四位專家確認內容效度，七個次量表之信度係數alphas皆大於.70。結果：有331位自陳曾使用俱樂部藥物之矯正機構青少年參與研究。研究對象愛滋知識平均答對率為66%；有性交經驗比例為78.2%；過去性交時，22.8%曾使用保險套；迴歸分析發現保險套使用行為意向與原型、意願及主觀規範三個變項有關；其中原型及意願能解釋11%的變異量。建議：高關懷青少年有性交經驗比例高，使用保險套比例低，建議矯正機構內應加強性教育。原型及意願可做為研擬青少年危險行為之設計內容。

Aim: This study aims to investigate safer sex intention amongst club-drug using adolescents. Methods: Participants were adolescents in Taiwan correctional facilities. We used theory of planned behavior with Prototype and Willingness as the study framework. Based on previous studies, a structured questionnaire was developed, including HIV/AIDS knowledge, subjective norms, attitude towards condom use, perceived behavior control of condom use, condom use prototype, willingness, and intention to use in the future. The questionnaire items were reviewed by 4 experts for content validity and internal consistency coefficients of these 7 subscales were more than .70. Results: The study participants were 331 adolescents who self-reported ever club drug use. Of participants, 66% had correct HIV-related knowledge and 78.2% had sexual experience. Of sexually active participants, 22.8% used condoms. Results from multiple regression analysis showed that gender, social norm, prototype and willingness are associated with condom use intention. Prototype and willingness can explain 11% of the intention variance. Conclusion and suggestion: This study provide evidence that high-risk adolescents have high percentage of sexual experience and less likely to use condoms during coitus, indicating that sexuality education should be strengthened in the correctional facilities. Prototype and willingness should be considered when the sexuality condom use curriculum is designed.
