Substance use disorders frequently co-occur with internalizing disorders, such as depression and anxiety, particularly among emerging adults in treatment. While a growing literature has examined bidirectional associations between internalizing symptoms and substance use, findings remain mixed. The present study investigated whether social recovery capital (SRC) mediated bidirectional internalizing symptoms and substance use behaviors associations.
Emerging adults ( = 302, 74% male sex assigned at birth, 95% White) were recruited from a residential substance use treatment facility and assessed at treatment baseline, 1-, 3-, 6-, and 12-month follow-ups (71% retention rate at the 12-month follow-up). Latent growth curve models with structured residuals, which disaggregate between- (i.e., growth processes) and within-person effects (i.e., cross-sectional and lagged associations), examined reciprocal associations between internalizing symptoms, SRC, and substance use outcomes.
Results indicated that SRC and percent days abstinent increased over time, while internalizing symptoms decreased. Substance use consequences initially decreased but increased after the 3-month follow-up. At the within-person level, there was no support for the central hypothesis that SRC would mediate internalizing symptom-substance use associations. Greater internalizing symptoms were contemporaneously associated with higher substance use consequences. More SRC was contemporaneously associated with higher percent days abstinent and lower internalizing symptoms.
Contemporaneous associations between more SRC and lower internalizing symptoms and greater percent days abstinent suggest SRC may facilitate reductions of co-occurring substance use and internalizing symptoms. Future studies should explore alternative timescales and use more comprehensive measures of SRC. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
物质使用障碍常与内化性障碍（如抑郁和焦虑）同时出现，在接受治疗的青少年中尤为常见。虽然越来越多的文献研究了内化症状与物质使用之间的双向关联，但研究结果仍不一致。本研究调查了社会恢复资本（SRC）是否介导了内化症状与物质使用行为之间的双向关联。
从一家住院物质使用治疗机构招募了青少年（n = 302，74%出生时被指定为男性，95%为白人），并在治疗基线、1个月、3个月、6个月和12个月随访时进行评估（12个月随访时的保留率为71%）。具有结构化残差的潜在增长曲线模型，该模型区分组间效应（即增长过程）和个体内效应（即横断面和滞后关联），研究了内化症状、SRC和物质使用结果之间的相互关联。
结果表明，SRC和戒断天数百分比随时间增加，而内化症状减少。物质使用后果最初减少，但在3个月随访后增加。在个体内水平上，没有证据支持SRC会介导内化症状与物质使用关联的核心假设。更高的内化症状与更高的物质使用后果同时相关。更多的SRC与更高的戒断天数百分比和更低的内化症状同时相关。
更多的SRC与更低的内化症状以及更高的戒断天数百分比之间的同时关联表明，SRC可能有助于减少同时出现的物质使用和内化症状。未来的研究应探索替代时间尺度，并使用更全面的SRC测量方法。（PsycInfo数据库记录（c）2025美国心理学会，保留所有权利）
