以前评估认知行为疗法(CBT)治疗广泛性焦虑症(GAD)有效性的荟萃分析使用一般的焦虑测量来评估症状的严重程度和改善情况(例如，汉密尔顿焦虑评定量表或焦虑的综合测量)。虽然这些研究提供了信息，但这些研究并没有提供足够的证据来证明CBT是否显著减少GAD的主要症状：病理性担忧。目前的荟萃分析采用了严格的纳入标准来评价相关结果研究，包括使用宾夕法尼亚州立大学忧虑问卷作为主要结果变量。结果显示大的总体效应大小(ES)受年龄和治疗方式的影响。具体地说，年轻人和个人治疗的收益最大。分析还显示，在6个月和12个月的随访中，总体保持了增长。讨论了不同治疗方案的临床意义，以及CBT疗效差异的可能解释。(C)2007爱思唯尔有限公司。保留所有权利。
Previous meta-analyses assessing the effectiveness of Cognitive Behavioural Therapy (CBT) for Generalized Anxiety Disorder (GAD) used general measures of anxiety to assess symptom severity and improvement (e.g., Hamilton Anxiety Ratings Scale or a composite measure of anxiety). While informative, these studies do not provide sufficient evidence as to whether CBT significantly reduces the cardinal symptom of GAD: pathological worry. The current meta-analysis employed stringent inclusion criteria to evaluate relevant outcome studies, including the use of the Penn State Worry Questionnaire as the main outcome variable. Results showed a large overall effect size (ES) that was moderated by age and modality of treatment. Specifically, the largest gains were found for younger adults and for individual treatment. Analyses also revealed overall maintenance of gains at 6- and 12-month follow-up. Clinical implications of different treatment packages are discussed, as well as potential explanations for the differential effectiveness of CBT. (C) 2007 Elsevier Ltd. All rights reserved.
