Social support may be a critical mechanism in the treatment of co-occurring substance use disorder (SUD) and posttraumatic stress disorder (PTSD). However, no studies have examined how social support changes as a function of treatment or predicts treatment outcome in a Veteran population with co-occurring SUD and PTSD.
The current study is a secondary analysis that examined social support over the course of treatment for co-occurring SUD and PTSD (N = 81). Analyses were conducted to examine if a) social support predicts change in substance use and PTSD symptoms, respectively, over the course of treatment and during follow-up, and b) substance use and PTSD symptoms, respectively, predicts change in social support over treatment and during follow-up.
The findings revealed that between-person social support moderated decreases in substance use ( = -0.17, = 0.07, 0.017) and PTSD symptom severity ( = -0.12, = 0.05, = 0.009) during treatment but not during follow-up. Within-person substance use and PTSD symptom severity predicted social support but substance use and PTSD symptoms did not moderate changes in social support during treatment or follow-up.
The findings highlight the critical role of social support during treatment in enhancing outcomes for individuals with co-occurring SUD and PTSD.
社会支持可能是同时存在物质使用障碍（SUD）和创伤后应激障碍（PTSD）的治疗中的关键机制。然而，尚无研究考察社会支持如何随治疗而变化，或在同时患有SUD和PTSD的退伍军人人群中预测治疗结果。
本研究是一项二次分析，考察了同时患有SUD和PTSD的患者（N = 81）在治疗过程中的社会支持情况。进行分析以检验：a）社会支持是否分别在治疗过程中和随访期间预测物质使用和PTSD症状的变化，以及b）物质使用和PTSD症状是否分别在治疗过程中和随访期间预测社会支持的变化。
研究结果显示，个体间社会支持在治疗期间而非随访期间调节了物质使用的减少（β = -0.17，SE = 0.07，p = 0.017）和PTSD症状严重程度的降低（β = -0.12，SE = 0.05，p = 0.009）。个体内物质使用和PTSD症状严重程度预测了社会支持，但物质使用和PTSD症状在治疗或随访期间并未调节社会支持的变化。
研究结果凸显了治疗期间社会支持在改善同时患有SUD和PTSD的个体的治疗效果方面的关键作用。
