Abstract

Objective: Black emerging adults are significantly impacted by substance misuse. Posttraumatic stress disorder (PTSD) is associated with heightened substance misuse among Black emerging adults. However, limited research has identified protective factors that may influence the strength of the relation between PTSD and substance misuse in this population. Addressing this important limitation, the present study examined the potential moderating role of perceived social support in the association between PTSD symptoms and substance (i.e., alcohol and drug) misuse. Methods: Participants were 182 trauma-exposed Black emerging adults (M age = 20.50; 71.3% women) who completed self-report measures assessing PTSD symptoms, alcohol and drug misuse, and perceived social support. Results: PTSD symptoms were significantly and positively correlated with both alcohol and drug misuse. Moderation analyses indicated that positive relations between PTSD symptoms and both alcohol and drug misuse were only significant among Black emerging adults with lower (but not higher) levels of perceived social support. Conclusions: These findings suggest the potential utility of addressing social support in the assessment and treatment of substance misuse in trauma-exposed Black emerging adults.

摘要

目标：黑人新兴成年人受到物质滥用的显着影响。创伤后应激障碍 (PTSD) 与新兴黑人成年人的物质滥用加剧有关。然而，有限的研究已经确定了可能影响这一人群中 PTSD 与药物滥用之间关系强度的保护因素。针对这一重要局限性，本研究检验了感知到的社会支持在 PTSD 症状与物质（即酒精和药物）滥用之间的关联中的潜在调节作用。方法：参与者是 182 名暴露于创伤的黑人新兴成年人（M年龄 = 20.50；71.3% 为女性），他们完成了评估 PTSD 症状、酒精和药物滥用以及感知社会支持的自我报告措施。结果： PTSD 症状与酒精和药物滥用显着正相关。适度分析表明，PTSD 症状与酒精和药物滥用之间的正相关关系仅在感知社会支持水平较低（而非较高）的黑人新兴成年人中显着。结论：这些研究结果表明，解决社会支持问题在评估和治疗受过创伤的黑人新兴成年人的药物滥用方面具有潜在效用。
