EXPLAINING RELAPSE IN HEROIN ADDICTION

这项纵向研究调查了复发的原因， 鸦片成瘾的治疗 使用结构化面试时间表， 研究小组在三个时间点采访了240名受试者： 治疗结束后，六个月后，和十二个月后。 我们 将使用多变量统计分析（回归、逻辑回归 和因素分析），从结果中进行因果推断 非实验数据。 该分析试图估计一个因果模型， 结合了Wikler，Winick， Lindesmith，Marlatt，Brill，Waldorf，Vaillant，and McAuliffe. 结果 应该提出预防复发的方法， 用于后期戒毒治疗和康复项目。 该提案寻求持续一年的资金，以完成为期12个月的 对75名受试者进行随访，并对数据进行分析。 样本和相关数据从以前的研究由校长 调查员 最初的拨款只收到了其批准资金的40% 在第一年，科目更难招募（部分 由于官僚作风）比原来预期的。 招聘问题 现在已经解决了，后续的采访正在一个很好的完成， 率，额外的时间和金钱将允许完成研究， 原计划和分析相关的从以前的研究。

This longitudinal study investigates the causes of relapse following treatment of opiate addiction. Using structured interview schedules, the study team is interviewing 240 subjects at three points in time: upon completion of treatment, after six months, and after twelve months. We will use multivariate statistical analyses (regression, logistic regression and factor analysis) to make causal inferences from the resulting non-experimental data. The analysis seeks to estimate a causal model of relapse that incorporates ideas from the writings of Wikler, Winick, Lindesmith, Marlatt, Brill, Waldorf, Vaillant, and McAuliffe. The results should suggest ways of preventing relapse, and will be especially relevant for the late stages of drug treatment and for aftercare programs. This proposal seeks continued funding for one year to complete twelve-month followup interviews for 75 subjects and to analyze the data from this sample and relevant data from a previous study by the Principal Investigator. The original grant received only 40% of its approved funding in the first-year and subjects have been more difficult to recruit (partly due to red tape) than originally anticipated. With recruitment problems now solved and the followup interviews being completed at an excellent rate, the additional time and money will allow completion of the study as originally planned and analysis of relevant from the previous study.
