● 中文摘要：

　　依據「門檻假說」，典型的青少年開始使用物質的順序常是從使用低階毒品再進展至使用高階毒品，先前已使用低階毒品，將提升未來使用高階毒品的危險性。本研究的目的，即在於把握因使用二級毒品等相對低階毒品而接受觀察勒戒的有限時間，為青少年個案進行高階毒品如安非他命、海洛因的本質、使用後對生理心理所造成的殘害、拒絕使用的技巧等系統的介紹和教育宣導。本研究發展介紹安非他命和海洛因的相關知識、法律和拒絕使用技巧的青少年反毒介入宣導教材和書面教育資料，並從兩所少年觀護所附設觀察勒戒處所中，邀請30位搖頭丸使用者和30位安非他命使用者進入介入組，另外30位搖頭丸使用者和30位安非他命使用者為對照組，以個案對照和前後測的研究設計，比較接受個別的教育介入和僅接受書面教育資料兩種教育宣導模式在提升青少年對於高階毒品的知識、拒毒決心和處理使用情境的技巧、改變對於毒品的態度之成效差異。結果發現：個別教育介入能有效提升對於海洛因和安非他命的正確知識，但在態度方面則無明顯效果；在海洛因部分，介入教材能有效提升青少年處理初次使用海洛因情境的自我效能和提升拒絕使用海洛因的把握，在安非他命部份，介入組比對照組有較強有把握能拒絕使用毒品的傾向，但在有效處理初次使用安非他命情境的自我效能方面，兩組則無顯著差異。

● English Abstract:

     The gateway hypothesis has had an influence in the design of prevention strategies for adolescent substance use over the past decades. According to the gateway hypothesis, the typical sequence of drug initiation in adolescence begins with either alcohol or cigarettes, followed by marijuana, which is then followed by other illicit drugs, such as cocaine, methamphetamine (MAMP), and heroin. The adolescents who have used lower-stage drugs have higher risk to develop use of higher-stage drugs than those who have never used lower-stage drugs. The purposes of this study are to develop interventional strategies for the adolescents who are detained due to using ecstasy or MAMP to increase their knowledge about the harmful characteristics of heroin and MAMP, change their attitudes toward heroin and MAMP use, and the confidence and self-efficacy to refuse using heroin and MAMP in the high-risk situations. We invited 60 juvenile drug users (30 using MAMP and 30 using ecstasy) into the intervention group and 60 (30 using MAMP and 30 using ecstasy) into the control group. The results indicated that the interventional strategies can improve the knowledge about heroin and MAMP, increase the confidence and self-efficacy to refuse using heroin in the high-risk situations, and have the tendency to increase the confidence to refuse using MAMP in the high-risk situations.
