Abstract

Brief cognitive behavior therapy (bCBT) is effective in reducing symptoms of depression and anxiety disorders and improving health-related quality of life (HRQoL). However, the mechanisms through which cognitive behavior therapy impact HRQoL are not well understood. This study evaluated whether anxiety and depression symptom reduction is a mechanism of treatment for HRQoL outcomes.

Method: Using secondary data from a multisite, pragmatic, randomized trial, this study evaluated bCBT vs enhanced usual care in 16 VA community-based outpatient clinics. Ordinary least-squares path analysis testing multiple mediators was used to evaluate the role of change in depression and anxiety symptoms in the relationship between treatment condition and HRQoL.

Results: Receiving bCBT (vs. enhanced usual care) was significantly negatively associated with change (reduction) in depression and anxiety scores. The indirect effect of treatment on mental HRQoL was significant with change in depression scores as mediator. A similar pattern was observed for physical HRQoL and change in anxiety scores as mediator.

Conclusion: Findings suggest reduction of depression and anxiety symptoms as a mechanism through which bCBT for depression promoted improvements in HRQoL, with important implications for understanding how CBT impacts functioning, as well as the utility of bCBT in nontraditional mental health settings.

通过简短认知行为疗法减少症状在改善健康相关生活质量中的作用。

简短认知行为疗法（bCBT）能有效减轻抑郁症和焦虑症的症状，改善与健康相关的生活质量（HRQoL）。然而，认知行为疗法影响 HRQoL 的机制尚不十分清楚。本研究评估了焦虑和抑郁症状的减轻是否是影响 HRQoL 结果的一种治疗机制：本研究利用一项多地点、务实、随机试验的二手数据，对退伍军人事务部 16 个社区门诊诊所的 bCBT 与增强型常规护理进行了评估。采用检验多重中介因素的普通最小二乘法路径分析来评估抑郁和焦虑症状的变化在治疗条件与 HRQoL 之间关系中的作用：结果：接受 bCBT（与加强型常规护理相比）与抑郁和焦虑评分的变化（降低）呈显著负相关。以抑郁评分的变化为中介，治疗对心理 HRQoL 的间接影响是显著的。在身体的 HRQoL 方面也观察到类似的模式，以焦虑评分的变化作为中介：研究结果表明，抑郁和焦虑症状的减轻是抑郁症 bCBT 促进 HRQoL 改善的一个机制，这对了解 CBT 如何影响功能以及 bCBT 在非传统心理健康环境中的实用性具有重要意义：试验注册：ClinicalTrials.gov identifier：试验注册：ClinicalTrials.gov 标识符：NCT02466126。
