Recent advances in the understanding of worry have led to the development of treatments for generalized anxiety disorder (GAD). The present study tested a GAD treatment that targeted intolerance of uncertainty, erroneous beliefs about worry, poor problem orientation, and cognitive avoidance. Twenty-six primary GAD patients were randomly allocated to a treatment condition (n = 14) or a delayed treatment control condition (n = 12). Self-report, clinician, and significant other ratings assessed GAD and associated symptoms. The results show that the treatment led to statistically and clinically significant change at posttest and that gains were maintained at 6- and 12-month follow-ups. Furthermore, 20 of 26 participants (77%) no longer met GAD diagnostic criteria following treatment. With regard to the treatment's underlying model, the results show that intolerance of uncertainty significantly decreased over treatment and that gains were maintained at both follow-ups. Although nonspecific factors were not significant predictors of treatment outcome, their role in the treatment of GAD requires further investigation.
在对担忧的理解方面取得的最新进展促使了针对广泛性焦虑症（GAD）的治疗方法的发展。本研究测试了一种针对对不确定性的不耐受、对担忧的错误信念、不良问题取向和认知回避的广泛性焦虑症治疗方法。26名原发性广泛性焦虑症患者被随机分配到治疗组（n = 14）或延迟治疗对照组（n = 12）。通过自我报告、临床医生和重要他人的评分来评估广泛性焦虑症及相关症状。结果显示，该治疗在测试后导致了具有统计学意义和临床意义的变化，并且在6个月和12个月的随访中疗效得以维持。此外，26名参与者中有20名（77%）在治疗后不再符合广泛性焦虑症的诊断标准。关于该治疗的潜在模型，结果显示，在治疗过程中对不确定性的不耐受显著降低，并且在两次随访中疗效均得以维持。尽管非特异性因素不是治疗结果的显著预测因素，但它们在广泛性焦虑症治疗中的作用仍需进一步研究。
