Many people who use drugs (PWUD) are coerced into receiving treatment. This study aimed to assess changes in substance use and related outcomes before versus after treatment in people coerced into treatment, voluntarily attending treatment or not attending treatment.
Data from three linked prospective cohort studies of PWUD were used. McNemar's test and non-linear growth curve modeling were employed to: (a) assess changes in substance use patterns before and after coerced addiction treatment and (b) compare these changes with changes in PWUD who (1) voluntarily accessed and (2) did not access treatment.
Vancouver, Canada.
A total of 3196 community-recruited PWUD.
The outcome variables were substance use and related outcomes assessed by self-reported questionnaire. The input variable was self-reported coerced addiction treatment (defined as being forced into addiction treatment by a doctor or the criminal justice system), voluntary treatment versus no treatment.
Between September 2005 and June 2015, 399 (12.5%) participants reported being coerced into addiction treatment. In McNemar's test, there were no statistically significant reductions in within-group substance use outcomes for people coerced into treatment, voluntarily attending treatment or not attending treatment. In non-linear growth curve analyses, there were no statistically significant differences in the before and after substance use patterns between those coerced into treatment versus either of the two control groups (all P > 0.05). In subanalyses, we found no statistically significant differences in substance use patterns between people who reported formal coerced treatment through the criminal justice system and people who reported informal coerced treatment through a physician.
Among PWUD in Vancouver, Canada, there appear to be no statistically significant improvements in substance use outcomes among those reporting coerced addiction treatment, those voluntarily accessing treatment, and those not attending treatment.
许多吸毒者（PWUD）是被迫接受治疗的。本研究旨在评估被强制、自愿或未接受治疗的吸毒者在治疗前后物质使用及相关结果的变化。
本研究使用了三项关于吸毒者的前瞻性队列研究的数据。采用 McNemar 检验和非线性增长曲线模型：（a）评估被强制接受成瘾治疗前后物质使用模式的变化；（b）将这些变化与自愿接受治疗和未接受治疗的吸毒者的变化进行比较。
加拿大温哥华。
共纳入 3196 名社区招募的吸毒者。
通过自我报告问卷评估物质使用和相关结果，作为因变量；自我报告的强制成瘾治疗（定义为医生或刑事司法系统强迫接受成瘾治疗）、自愿治疗与不治疗，作为自变量。
2005 年 9 月至 2015 年 6 月，399 名（12.5%）参与者报告曾被强制接受成瘾治疗。在 McNemar 检验中，被强制治疗、自愿治疗和未治疗的人群中，组内物质使用结果未见统计学显著降低。在非线性增长曲线分析中，被强制治疗的人群与两个对照组（均为 P>0.05）之间的治疗前后物质使用模式无统计学显著差异。在亚组分析中，我们发现报告通过刑事司法系统接受正式强制治疗和报告通过医生接受非正式强制治疗的人群之间的物质使用模式无统计学显著差异。
在加拿大温哥华的吸毒者中，报告接受强制成瘾治疗、自愿接受治疗和未接受治疗的人群中，物质使用结果似乎没有统计学显著改善。
