Abstract: In recent years, adolescent drug use is becoming more and more serious. The drug use behavior of reform school students is worse than the drug use behavior of middle school students (Lin, Su, Hu, & He, 2010; Xie, Bu, Liang, Mai, & Zhao, 2007). The younger adolescent beginning to use drug is, the bigger possibility of using drug in whole life is (Lin, Fan, Fang, Tan, & Li, 2010). Drug use greatly endangers adolescents health and may make them death. They can lead to serious adolescents behavioral problems, such as adolescents crime and suicide (Estévez & Emler, 2011; Ma, Guo, & Pan, 2010; Tang et al., 2009). Therefore, more attention should be paid to drug use among reform school students. It is very necessary to study the potential mechanisms of drug use of reform school students so as to design prevention and intervention programs. The present study aimed to explore characteristics of drug use of reform school students and to explore the mediated moderation among sensation seeking, stressful life events, affiliation with deviant peers, and drug use after controlling for several demographic variables. A sample of 523 reform school students of 9 reform schools (442 boys and 81 girls, Mage=14.13±0.84) was recruited in the study to complete self-report questionnaires. The self-report questionnaires used in this study included sensation seeking scale, stressful life events scale, affiliation with deviant peers questionnaire, and drug use questionnaire． The results indicated that: (1) reform school students had a high level of drug use. About 32% of the reform school students used drugs, characterized by using drugs in a younger age, mainly using new drugs; (2) reform school students’ sensation seeking was a risk factor of drug use, which confirms the results from earlier studies that have found a positive relationship between sensation seeking and adolescents drug use; (3) stressful life events moderated the effect of sensation seeking on drug use; (4) affiliation with deviant peers mediated this moderation effect. The theoretical and practical implications of the results was further discussed. Future direction in the field of the relationship between sensation seeking and adolescent substance use was prospected.

摘要： 以523名工读生为调查对象，考察工读生毒品使用特点，并在控制相关人口学变量后，探讨感觉寻求、压力性生活事件、结交不良同伴与工读生毒品使用的关系。结果显示：（1）工读生的毒品使用行为严重，34.2%的工读生曾使用过毒品，毒品使用呈现低龄化、以吸食新型毒品为主的趋势。（2）工读生的感觉寻求是毒品使用的风险因素。（3）压力性生活事件对感觉寻求与毒品使用之间的关系具有风险增强的调节效应。（4）这种调节效应以结交不良同伴为中介变量。因此，感觉寻求对工读生毒品使用的影响是有中介的调节效应。研究结果对青少年毒品使用的预防和干预有重要的理论价值和参考价值。
