People with posttraumatic stress disorder (PTSD) experience a wide array of symptoms, often accompanied by significant functional and quality of life impairments. Evidence-based psychotherapies are effective for alleviating symptoms in this group, but functional outcomes following psychotherapy are understudied. This study aimed to synthesize existing work on functional outcomes of psychotherapy to conduct a meta-analytic investigation examining whether people with PTSD experience significant improvements in functioning and quality of life following a course of psychotherapy. A literature search was conducted for studies reporting results of randomized clinical trials of psychotherapies for people diagnosed with PTSD that included a functional or quality of life outcome measured at pre- and post-intervention. Both between-groups and within-groups analyses were conducted using a random effects model. Fifty-six independent samples were included. Results suggest that, on average, people with PTSD experience significant, moderate improvement in functional outcomes after a course of psychotherapy. Taken together, this meta-analysis represents a substantial advance in our understanding of functional outcomes of psychotherapy for people with PTSD. Findings suggest that psychotherapy is one vehicle through which functional outcomes may be improved for this group, though notably to a lesser degree than symptom improvement.
创伤后应激障碍（PTSD）患者会出现多种症状，通常伴有明显的功能和生活质量受损。循证心理疗法对减轻该群体的症状有效，但心理治疗后的功能结果研究不足。本研究旨在综合现有的心理治疗功能结果研究，进行荟萃分析，以考察 PTSD 患者在接受一系列心理治疗后，其功能和生活质量是否会显著改善。对报告 PTSD 诊断患者心理治疗随机临床试验结果的研究进行了文献检索，这些研究包括在干预前后测量的功能或生活质量结果。使用随机效应模型进行了组间和组内分析。纳入了 56 个独立样本。结果表明，平均而言，PTSD 患者在接受一系列心理治疗后，其功能结果会出现显著、中度的改善。总的来说，这项荟萃分析代表了我们对 PTSD 患者心理治疗功能结果的理解取得了重大进展。研究结果表明，心理治疗是改善该群体功能结果的一种手段，尽管症状改善的程度明显较低。
