We used reports ( = 208) of drug-free friendships and alcohol and drug use by people diagnosed with substance use disorder in order to investigate their annual change trajectories across 4 years after treatment and the association between these trajectories and debut age and gender. The participants were recruited from the Stavanger region, Norway. Using cross-sectional analysis, we first examined the relationship between "alcohol and drug use" and "drug-free friendships" across the five follow-ups. We tested whether these associations were significant using chisquare chi-squared tests. Second, we developed three latent growth curve models examining the association between "alcohol and drug use" and "drug-free friendships". Our analysis displays a stable drug-free friendships pattern across follow-ups. Only in the fourth follow-up was there a significant association between lower "alcohol and drug use" and having "drug-free friendships" (χ = 18.27, df = 8, < .05). In model 1, we found no association between gender, debut age, and alcohol and drug use; model 2 had significant variance on intercept but not on slope; model 3 had good fit (χ = 44.33, df = 39, comparative fit index = 0.98, root mean square error of approximation = 0.027). However, we did not find any significant regression path between the "alcohol and drug use" and "drug-free friendships" slopes. Drug-free relationships were in the studied cohort group found to have little influence on reducing alcohol and drug use, while debut age and gender were unrelated to use trajectories across 4 years. We suggest that future research should focus on the frequency and quality of drug-free friendships and participants' friendship assessments because previous research has found such relationships to facilitate recovery.
我们使用了208份关于被诊断患有物质使用障碍的人的无毒品友谊以及酒精和药物使用情况的报告，以调查他们在治疗后4年的年度变化轨迹，以及这些轨迹与初次使用年龄和性别的关联。参与者是从挪威斯塔万格地区招募的。通过横断面分析，我们首先在五次随访中研究了“酒精和药物使用”与“无毒品友谊”之间的关系。我们使用卡方检验来检验这些关联是否显著。其次，我们开发了三个潜在增长曲线模型，以研究“酒精和药物使用”与“无毒品友谊”之间的关联。我们的分析显示，在整个随访过程中，无毒品友谊模式是稳定的。仅在第四次随访中，较低的“酒精和药物使用”与拥有“无毒品友谊”之间存在显著关联（χ = 18.27，自由度 = 8，P <.05）。在模型1中，我们发现性别、初次使用年龄与酒精和药物使用之间没有关联；模型2在截距上有显著方差，但在斜率上没有；模型3拟合良好（χ = 44.33，自由度 = 39，比较拟合指数 = 0.98，近似均方根误差 = 0.027）。然而，我们没有在“酒精和药物使用”与“无毒品友谊”的斜率之间发现任何显著的回归路径。在研究的队列组中发现，无毒品关系对减少酒精和药物使用的影响很小，而初次使用年龄和性别与4年的使用轨迹无关。我们建议未来的研究应关注无毒品友谊的频率和质量以及参与者的友谊评估，因为先前的研究发现此类关系有助于康复。
