Previous research has established efficacy of cognitive behavioral therapy (CBT) for anxiety disorders, yet it has not been widely assessed in routine community clinic practices. Efficacy research sacrifices external validity to achieve maximum internal validity. Recently, effectiveness research has been advocated as more ecologically valid for assessing routine clinical work in community clinics. Furthermore, there is a lack of effectiveness research in group CBT. This study aims to extend existing research on the effectiveness of CBT from individual therapy into group therapy delivery. It aimed also to examine outcome using not only symptom measures, but also measures of related symptoms, cognitions, and life quality and satisfaction. Results from a cohort of patients with various anxiety disorders demonstrated that treatment was effective in reducing anxiety symptoms to an extent comparable with other effectiveness studies. Despite this, only 43% of individuals showed reliable change, and 17% were 'recovered' from their anxiety symptoms, and the post-treatment measures were still significantly different from the level of anxiety symptoms observed in the general population.
先前的研究已证实认知行为疗法（CBT）对焦虑症有效，但在社区诊所的常规实践中尚未得到广泛评估。疗效研究牺牲了外部效度以实现最大的内部效度。最近，有人提倡开展效果研究，认为其在评估社区诊所的常规临床工作方面具有更高的生态效度。此外，针对团体认知行为疗法的效果研究较少。本研究旨在将现有的关于认知行为疗法有效性的研究从个体治疗扩展到团体治疗。该研究还旨在不仅使用症状测量指标，而且使用相关症状、认知、生活质量和满意度的测量指标来检验治疗结果。一组患有各种焦虑症的患者的研究结果表明，该治疗在减轻焦虑症状方面是有效的，其程度与其他效果研究相当。尽管如此，只有43%的个体显示出可靠的改善，17%的个体从焦虑症状中“康复”，并且治疗后的测量结果仍与普通人群中观察到的焦虑症状水平存在显著差异。
