There is growing interest in the impact of substance use on both the individual consumer's subjective wellbeing (SWB) and the reduced SWB of those closely connected to him or her. The study aimed to compare SWB among substance users ('consumers') and the parents or partners affected by another's substance use, and to evaluate the effect of counselling on changed SWB to 6 months.
The study used longitudinal data from a not-for-profit treatment service based in Perth, Australia. Subjective wellbeing was assessed with the Personal Wellbeing Index (PWI) at baseline and 6 months. Data were compared to national norms (mean 75.97) with one sample t tests. Change in PWI scores was assessed with generalised linear mixed models, controlling for age, gender, group (consumers versus parents or partners), psychological distress (Kessler-10) and social connectedness (Lubben).
Of 220 participants, 136 (62%) were consumers and 84 (38%) were parents or partners. At 6 months 123 (56%) were re-interviewed. At baseline, both consumers (mean 53.7) and parents or partners (mean 66.1) had significantly lower PWI scores than national norms. At 6 months, only the substance users' PWI scores remained significantly lower (mean 67.8). Subjective wellbeing significantly increased with time (β = 5.52; 95% confidence interval 3.15, 7.90), with no significant time by group interaction.
Both groups showed significant decrements in SWB compared with the general population but with improvements over the study period. However, the lack of a control group prevents definitive assertions on causality for improved SWB.
人们越来越关注物质使用对个体消费者的主观幸福感（SWB）以及与其密切相关的人的降低的 SWB 的影响。本研究旨在比较物质使用者（“消费者”）和受他人物质使用影响的父母或伴侣的 SWB，并评估咨询对 6 个月时 SWB 变化的影响。
该研究使用了澳大利亚珀斯非营利性治疗服务的纵向数据。在基线和 6 个月时使用个人幸福感指数（PWI）评估主观幸福感。使用单样本 t 检验将数据与全国平均值（均值 75.97）进行比较。使用广义线性混合模型评估 PWI 评分的变化，控制年龄、性别、组（消费者与父母或伴侣）、心理困扰（Kessler-10）和社会联系（Lubben）。
在 220 名参与者中，136 名（62%）是消费者，84 名（38%）是父母或伴侣。在 6 个月时，有 123 名（56%）接受了重新访谈。在基线时，消费者（均值 53.7）和父母或伴侣（均值 66.1）的 PWI 评分均明显低于全国平均值。在 6 个月时，只有物质使用者的 PWI 评分仍然明显较低（均值 67.8）。主观幸福感随着时间的推移显著增加（β=5.52；95%置信区间 3.15，7.90），组间无显著的时间交互作用。
与一般人群相比，两组的 SWB 都明显下降，但在研究期间有所改善。然而，缺乏对照组使得对于改善的 SWB 的因果关系无法做出明确的断言。
