Drug camps have been used to treat substance use in Thailand since the 2000s. However, some researchers have argued that drug camp’s effectiveness was insufficient to help the attendants to be abstinent. This study explored the drug camp’s effects by comparing a drug camp model, developed based on 12-Step, cognitive–behavioral theory, and group psychotherapy theory with one that currently has been used in drug camps in Thailand. One drug camp in Nakhon Ratchasima was selected as an area of study. Drug attendants who lived in Khong district were assigned into a 12-Step group, which used the new model (n = 35). Meanwhile, other attendants who lived in other districts in Nakhon Ratchasima were assigned into a treatment-as-usual group (n = 57). Methamphetamine use behavior was assessed before and after the camp. There was a significant difference between the 12-Step and treatment-as-usual group on the level of the attendants’ average methamphetamine use after controlling average methamphetamine use before drug camp [F (1,84) = 91.76, p < 0.001]. Comparing the estimated marginal means showed that average methamphetamine use 1 year after drug camp of the 12-Step group (mean = 0.74, SD = 1.79) was lower than the treatment-as-usual group (mean = 11.25, SD = 14.06). One year after camp, Cox proportional hazards regression indicated that the chances of the attendants in the 12-Step group returning to methamphetamine use were reduced by 88% (adjusted hazard = 0.120, 95% CI 0.061–0.023) after controlling for confounding variables, including age, marital status, education, and occupation.

药物营在使用新的行为改变模型治疗甲基苯丙胺使用中的作用：一项准实验研究

自 2000 年代以来，毒品集中营一直被用于治疗泰国的药物滥用。然而，一些研究人员认为，毒品集中营的有效性不足以帮助服务员戒酒。本研究通过比较基于 12 步法、认知行为理论和团体心理治疗理论开发的毒品集中营模型与目前在泰国毒品集中营中使用的模型，探讨了毒品集中营的影响。呵叻府的一个毒品营被选为研究领域。居住在 Khong 区的药房服务员被分配到一个 12 步组，该组使用新模型（n = 35）。与此同时，住在呵叻其他地区的其他服务员被分配到一个照常治疗组（n = 57）。在营地前后对甲基苯丙胺的使用行为进行了评估。在控制毒品集中营前平均甲基苯丙胺使用量后，12 步组和照常治疗组之间在服务员平均甲基苯丙胺使用水平上存在显着差异 [F (1,84) = 91.76, p < 0.001]。比较估计的边际平均值表明，12-Step 组（平均值 = 0.74，SD = 1.79）在毒品集中营后 1 年的平均甲基苯丙胺使用量低于常规治疗组（平均值 = 11.25，SD = 14.06）。训练营一年后，Cox 比例风险回归表明，在控制混杂变量后，12 步组中的服务员恢复使用甲基苯丙胺的机会降低了 88%（调整后的风险 = 0.120，95% CI 0.061–0.023），包括年龄、婚姻状况、教育和职业。
