Abstract

Background: Cognitive behavioural therapy (CBT) is an empirically supported treatment for generalized anxiety disorder (GAD). Little is known about the effectiveness of CBT for GAD in real-world treatment settings.

Aim: This study investigated the effectiveness of group CBT and predictors of treatment response in an out-patient hospital clinic.

Method: Participants (n = 386) with GAD participated in 12 sessions of group CBT at an out-patient clinic. Of those who provided at least partial data (n = 326), 84.5% completed treatment. Most questionnaires were completed at pre- and post-treatment; worry severity was assessed weekly.

Results: Group CBT led to improvements in chronic worry (d = -0.91, n = 118), depressive symptoms (d = -1.22, n = 172), GAD symptom severity (d = -0.65, n = 171), intolerance of uncertainty (IU; d = -0.46, n = 174) and level of functional impairment (d = -0.35, n = 169). Greater pre-treatment GAD symptom severity (d = -0.17, n = 293), chronic worry (d = -0.20, n = 185), functional impairment (d = -0.12, n = 292), and number of comorbid diagnoses (d = -0.13, n = 299) predicted greater improvement in past week worry over treatment. Biological sex, age, depression symptom severity, number of treatment sessions attended, and IU did not predict change in past week worry over time.

Discussion: These findings provide support for the effectiveness of group CBT for GAD and suggest the outcomes are robust and are either not impacted or are slightly positively impacted by several demographic and clinical factors.

在医院门诊环境中对广泛性焦虑症进行集体认知行为治疗的效果和预测因素。

背景：认知行为疗法（CBT认知行为疗法（CBT）是一种得到经验支持的治疗广泛性焦虑症（GAD）的方法。本研究调查了医院门诊中团体 CBT 的有效性以及治疗反应的预测因素：方法：患有 GAD 的参与者（n = 386）在门诊诊所参加了 12 个疗程的团体 CBT。在至少提供了部分数据的参与者（n = 326）中，84.5%完成了治疗。大多数调查问卷都是在治疗前和治疗后完成的；担心的严重程度每周评估一次：小组 CBT 改善了慢性担忧（d = -0.91，n = 118）、抑郁症状（d = -1.22，n = 172）、GAD 症状严重程度（d = -0.65，n = 171）、不确定性不容忍（IU；d = -0.46，n = 174）和功能障碍程度（d = -0.35，n = 169）。治疗前 GAD 症状严重程度（d = -0.17，n = 293）、长期担忧（d = -0.20，n = 185）、功能障碍（d = -0.12，n = 292）和合并诊断数量（d = -0.13，n = 299）越大，预示治疗后过去一周担忧的改善程度越大。生物性别、年龄、抑郁症状严重程度、接受治疗的疗程数和 IU 并不能预测过去一周担忧情绪随时间的变化：讨论：这些研究结果证明了小组 CBT 治疗严重抑郁强迫症的有效性，并表明其结果是可靠的，不会受到一些人口统计学和临床因素的影响，或者会受到轻微的积极影响。

期刊介绍： An international multidisciplinary journal aimed primarily at members of the helping and teaching professions. Behavioural and Cognitive Psychotherapy features original research papers, covering both experimental and clinical work, that contribute to the theory, practice and evolution of cognitive and behaviour therapy. The journal aims to reflect and influence the continuing changes in the concepts, methodology, and techniques of behavioural and cognitive psychotherapy. A particular feature of the journal is its broad ranging scope - both in terms of topics and types of study covered. Behavioural and Cognitive Psychotherapy encompasses most areas of human behaviour and experience, and represents many different research methods, from randomized controlled trials to detailed case studies.
