The effects of dialectical behavior therapy on generalized anxiety disorder have not been examined to date, whereas cognitive behavioral therapy is a well-known psychotherapy for generalized anxiety disorder.
This study investigated the effects of cognitive behavioral therapy versus dialectical behavior therapy on executive function and reduction of symptoms in generalized anxiety disorder.
In the present study, 72 generalized anxiety disorder patients were randomly assigned to one of two groups: dialectical behavior therapy or cognitive behavioral therapy. Evaluations were performed at baseline, post-test, and three months after interventions as a follow-up. Measures included the Structured Clinical Interview for DSM-IV Axis I disorders, the Generalized Anxiety Disorder scale, the Beck Anxiety Inventory, the Beck Depression Inventory, the Tower of London Task, and the Wisconsin Card Sorting Task.Results: The results of the present study showed that both groups had reduced scores for depression and anxiety and increased scores for executive function after the psychotherapies. These changes were maintained at follow-up.
Although depression and anxiety symptoms were significantly reduced by cognitive behavioral therapy, dialectical behavior therapy was more effective for improving executive function.
迄今为止，尚无研究探讨辩证行为疗法对广泛性焦虑障碍的影响，而认知行为疗法是一种广为人知的广泛性焦虑症心理疗法。
本研究旨在调查认知行为疗法与辩证行为疗法对广泛性焦虑障碍的执行功能和症状缓解的影响。
本研究将 72 例广泛性焦虑障碍患者随机分为两组：辩证行为疗法组或认知行为疗法组。在基线、后测和干预后三个月进行评估作为随访。评估工具包括 DSM-IV 轴 I 障碍的结构临床访谈、广泛性焦虑障碍量表、贝克焦虑量表、贝克抑郁量表、伦敦塔任务和威斯康星卡片分类任务。
本研究结果表明，两组患者在接受心理治疗后抑郁和焦虑评分均降低，执行功能评分升高。这些变化在随访中得以维持。
虽然认知行为疗法可显著降低抑郁和焦虑症状，但辩证行为疗法在改善执行功能方面更有效。
