Randomized controlled trial to evaluate the effects of psychometric feedback on treatment outcome and its mediators and moderators in outpatient psychotherapy

所要求的为期三年的研究项目在随机对照试验中调查心理测量反馈的有效性以及调节和调解因素。在这项预期的研究中，总共有N=423名患者将包括在特里尔大学心理治疗门诊中心申请认知行为治疗，并被诊断为抑郁症或焦虑症(SCID-访谈)。参与的治疗师将被随机分配到三种治疗条件中的一种(两个干预组和一个对照组)。这些患者将被随机分配给一名治疗师。对照组(CG；n=85)的患者将接受心理障碍监测，但他们的治疗师不会得到任何关于患者评估的反馈。在两个干预组(IG1：n=169；IG2：n=169)中，治疗师在计算机反馈门户中获得关于患者自我评估的反馈。IG2的治疗师还将获得临床支持工具。本研究的目的是在严格的设计(结构化临床访谈、重复评估的CG、治疗完整性控制)内评估心理测量反馈和临床支持工具在门诊心理治疗中的总体有效性。此外，还将检查反馈效果的中介变量(治疗时长和治疗师对负面变化的认识)和调节变量(对反馈的态度、反馈使用和诊断)。

The requested three-year research project investigates in a randomized controlled trial the effectiveness as well as moderating and mediating factors of psychometric feedback. In the intended study a total of N = 423 patients will be included who applied for cognitive-behavioral therapy at the psychotherapy outpatient center of the University of Trier and were diagnosed with a depressive or an anxiety disorder (SCID-interviews). Participating therapists will be randomly assigned in blocks to one of three treatment conditions (two intervention groups and one control group). The patients will in turn be randomly assigned to one therapist. Patients of the control group (CG; n = 85) will be monitored concerning their psychological impairment but their therapists will not be provided with any feedback about the patients assessments. In both intervention groups (IG1: n = 169; IG2: n = 169) the therapists are provided with feedback about the patients self-evaluation in a computerized feedback portal. Therapists of the IG2 will additionally be provided with clinical support tools. The aim of this research project is to evaluate the general effectiveness of psychometric feedback and clinical support tools within a strict design (structured clinical interview, CG with repeated assessments, control for treatment integrity) in outpatient psychotherapy. Additionally, mediating (treatment length and therapists awareness of negative change) and moderating variables (attitudes towards feedback, feedback usage and diagnoses) of the feedback effect will be examined.
