Based on the theory that generalized anxiety disorder (GAD) is maintained through a reactive and fused relationship with one's internal experiences and a tendency towards experiential avoidance and behavioral restriction, an acceptance-based behavior therapy (ABBT) was developed to specifically target these elements. Since ABBT has been shown to be an efficacious treatment in previous studies, the current study focuses on proposed mechanisms of change over the course of therapy. Specifically, the current study focuses on session-by-session changes in two proposed mechanisms of change: acceptance of internal experiences and engagement in meaningful activities. Overall, clients receiving ABBT reported an increase in the amount of time spent accepting internal experiences and engaging in valued activities. Change in both acceptance and engagement in meaningful activities was related to responder status at post-treatment and change in these two proposed mechanisms predicted outcome above and beyond change in worry. In addition, change in acceptance was related to reported quality of life at post-treatment.
基于广泛性焦虑障碍（GAD）是通过与个体内部体验的反应性和融合性关系以及对体验的回避和行为限制的倾向而维持的理论，开发了一种基于接纳的行为疗法（ABBT），专门针对这些因素。由于 ABBT 在以前的研究中已被证明是一种有效的治疗方法，因此本研究侧重于治疗过程中提出的变化机制。具体来说，本研究侧重于两个拟议的变化机制在每次治疗中的变化：对内部体验的接纳和参与有意义的活动。总体而言，接受 ABBT 的客户报告说，他们花在接受内部体验和参与有价值的活动上的时间有所增加。在接受和参与有意义的活动方面的变化与治疗后达到应答者状态有关，并且这两个拟议机制的变化预测了超过担忧变化的结果。此外，接受的变化与治疗后报告的生活质量有关。
