Mental health and substance use disorders are strong risk factors for homelessness. Understanding the role of transdiagnostic factors could help inform efforts to reduce homelessness among veterans with a range of disorders. Homeless veterans have high rates of trauma exposure, which can result in the depletion of social and emotional resources that may contribute to housing and employment stability. In this study, we evaluated the role of problems with emotional lability and interpersonal closeness as transdiagnostic socio-emotional factors that might interfere with efforts to achieve housing and employment stability.
The sample consisted of 346 homeless veterans with co-occurring disorders that were admitted to a U.S. Department of Veterans Affairs (VA) residential treatment program between 2004 and 2009. Assessments were conducted at treatment entry (baseline) and two follow-up timepoints (6- and 12-months). Variables used in the current analyses included history of interpersonal trauma exposure, emotional lability and interpersonal closeness at baseline and 6-months, and homelessness and employment problems during follow-up. Data were analyzed using structural equation modeling and counterfactually-defined mediation effects.
Veterans exposed to more trauma types experienced more baseline impairment and less improvement during treatment in emotional lability and interpersonal closeness. Problems with interpersonal closeness mediated 73% of the relationship between exposure to multiple traumas and homelessness, and 32%-61% of the relationship between trauma exposure and employment problems. Emotional lability mediated 36% of the relationship between exposure to multiple traumas and employment problems. Decomposition of indirect pathways revealed that indirect effects were primarily transmitted through changes during treatment, and not baseline levels.
Findings support a cumulative effect of trauma on persistence of socio-emotional deficits across treatment, which increased risk of homelessness and employment problems during follow-up. Greater attention and more targeted efforts should be directed at helping trauma-exposed veterans build socio-emotional resources during treatment.
心理健康和物质使用障碍是导致无家可归的重要风险因素。了解跨诊断因素的作用有助于为减少患有一系列疾病的退伍军人无家可归现象的努力提供信息。无家可归的退伍军人遭受创伤的比例很高,这可能导致社会和情感资源的枯竭,而这些资源可能有助于住房和就业的稳定。在本研究中,我们评估了情绪不稳定和人际亲密问题作为跨诊断社会情感因素的作用,这些因素可能会干扰实现住房和就业稳定的努力。
样本包括346名患有共病的无家可归退伍军人,他们于2004年至2009年期间进入美国退伍军人事务部(VA)的住院治疗项目。在治疗开始时(基线)和两个随访时间点(6个月和12个月)进行评估。当前分析中使用的变量包括人际创伤暴露史、基线和6个月时的情绪不稳定和人际亲密程度,以及随访期间的无家可归和就业问题。使用结构方程模型和反事实定义的中介效应分析数据。
经历更多创伤类型的退伍军人在治疗期间情绪不稳定和人际亲密程度方面的基线损伤更大,改善更少。人际亲密问题在多重创伤暴露与无家可归之间的关系中起到了73%的中介作用,在创伤暴露与就业问题之间的关系中起到了32%-61%的中介作用。情绪不稳定在多重创伤暴露与就业问题之间的关系中起到了36%的中介作用。间接路径的分解表明,间接效应主要通过治疗期间的变化而非基线水平传递。
研究结果支持创伤对整个治疗过程中社会情感缺陷持续存在的累积效应,这增加了随访期间无家可归和就业问题的风险。应更加关注并采取更有针对性的措施,帮助遭受创伤的退伍军人在治疗期间建立社会情感资源。
