Clients with generalized anxiety disorder (GAD) that demonstrate observer-coded treatment ambivalence benefit from the addition of motivational interviewing (MI) to cognitive behavioral therapy (CBT; Button, Westra, Constantino, & Antony, 2016). While observer-coded assessment of ambivalence and readiness for change is resource-intensive, the present study investigates the use of more efficient self-report measures to predict treatment outcomes. Participants (N = 85) with GAD received CBT or MI-CBT and completed self-report measures of readiness for change (Change Questionnaire, Miller & Johnson, 2008) and ambivalence (Treatment Ambivalence Questionnaire, Purdon, Rowa, Gifford, McCabe, & Antony, 2012). Greater self-reported baseline readiness for change was associated with lower posttreatment worry and symptom severity and faster reduction in worry. Self-reported ambivalence was not associated with outcomes. Patients with less concern about adverse consequences of treatment who received CBT experienced greater increases in readiness for change than those receiving MI-CBT. We discuss implications for using these measures in clinical settings.

自我报告的变化准备和治疗适应性测度是否可以预测广泛性焦虑症认知行为疗法的结果？

表现为观察者编码的矛盾情绪的广泛性焦虑症（GAD）患者可以通过在认知行为疗法中增加动机访谈（MI）来受益（CBT; Button，Westra，Constantino和Antony，2016）。虽然观察者编码的矛盾情绪和改变准备情况需要大量资源，但本研究调查了使用更有效的自我报告措施来预测治疗结果。患有GAD的参与者（N = 85）接受了CBT或MI-CBT，并完成了自我报告的变更准备情况（变更问卷，Miller＆Johnson，2008）和矛盾心理（治疗矛盾问卷，Purdon，Rowa，Gifford，McCabe，＆安东尼，2012年）。自我报告的基线变化准备程度更高，与较低的治疗后忧虑和症状严重程度以及更快的忧虑减轻相关。自我报告的矛盾情绪与结果无关。与接受MI-CBT的患者相比，接受CBT的患者对治疗不良后果的担忧较少，其改变的准备程度大大提高。我们讨论在临床环境中使用这些措施的意义。
