Cognitive therapy (CT) and applied relaxation (AR) as treatments of generalized anxiety disorder (GAD) were compared in a sample of 45 patients of a community mental health center, randomly allocated to condition. Patients were assessed before and after a 12-session treatment, and at one and six months follow-ups. There was a 20% drop out from CT and 15% from AR (NS), with some drop outs being considerably improved. Both completers and intention-to-treat analyses revealed that both treatments were effective (ESs of composite and specific measures ranging from 0.53 to 1.14). At one-month follow-up AR tended to do better than CT, with CT catching up with AR at six months. Recovery rates and proportions of patients showing reliable change were comparable to other studies on AR and CT, with 55% of CT and 53.3% of AR patients recovered on the STAI-trait at six-month follow-up. These results confirm that both CT and AR are effective treatments for GAD, and also that there is still room for improvement.
在一家社区心理健康中心的45名患者样本中，对认知疗法（CT）和应用放松疗法（AR）作为广泛性焦虑症（GAD）的治疗方法进行了比较，患者被随机分配到不同治疗组。在为期12节的治疗前后以及治疗后1个月和6个月的随访中对患者进行评估。认知疗法组有20%的患者退出，应用放松疗法组有15%的患者退出（无显著差异），一些退出者有明显改善。完成治疗者分析和意向性分析均显示两种治疗方法均有效（综合及特定测量指标的效应量范围为0.53至1.14）。在1个月的随访中，应用放松疗法的效果往往优于认知疗法，认知疗法在6个月时赶上了应用放松疗法。恢复率和显示可靠变化的患者比例与其他关于应用放松疗法和认知疗法的研究相当，在6个月的随访中，认知疗法组55%的患者和应用放松疗法组53.3%的患者在状态-特质焦虑量表（STAI-trait）上达到恢复。这些结果证实认知疗法和应用放松疗法都是治疗广泛性焦虑症的有效方法，并且仍有改进空间。
