The Norse Feedback (NF) is a questionnaire developed for patient-reported outcome monitoring with a clinical feedback system (PRO/CFS). As mental health is a concern after bariatric surgery, the use of the NF as part of PRO/CFS may be beneficial. The aim of this study is to test the reliability and validity of the NF in patients who have been accepted for or have undergone bariatric surgery. We performed separate robust confirmatory factor analyses (CFAs) to test the unidimensionality on 19 of the NF scales. We also performed correlation analyses on 19 of the NF scales with the Obesity-related Problems scale (OP). We included 213 patients. In the CFA analyses, three out of 12 scales with four or more items showed satisfactory psychometric properties in all goodness of fit indices (Suicidality, Need for Control and Self-Criticism). Four scales showed satisfactory psychometric properties in all indices but RMSEA (Somatic Anxiety, Substance Use, Social Safety and Cognitive Problems). Several of the scales demonstrated floor effects. In the correlation analyses, 18 of the 19 scales showed small-to-moderate correlation coefficients with the OP. Our demonstration of satisfactory psychometric properties on several important scales of the NF suggests that this tool may prove valuable in the routine follow-up of mental health in this population. However, further work is needed to innovate the NF for patients undergoing bariatric surgery.
北欧反馈（NF）是一种为患者报告的结果监测开发的问卷，带有临床反馈系统（PRO/CFS）。由于心理健康是减重手术后的一个关注点，因此将 NF 用作 PRO/CFS 的一部分可能是有益的。本研究的目的是测试已接受或已接受减重手术的患者的 NF 的可靠性和有效性。我们对 NF 的 19 个量表进行了单独的稳健验证性因素分析（CFA），以测试其单维性。我们还对 NF 的 19 个量表与肥胖相关问题量表（OP）进行了相关分析。我们纳入了 213 名患者。在 CFA 分析中，12 个四或更多项目的量表中有三个在所有拟合度指数（自杀意念、控制需求和自我批评）中表现出令人满意的心理测量特性。四个量表在所有指数中都表现出令人满意的心理测量特性，但 RMSEA 除外（躯体焦虑、物质使用、社会安全和认知问题）。几个量表表现出地板效应。在相关分析中，19 个量表中的 18 个与 OP 显示出小到中度的相关系数。我们在 NF 的几个重要量表上展示了令人满意的心理测量特性，这表明该工具在该人群的心理健康常规随访中可能具有价值。然而，需要进一步的工作来创新用于接受减重手术的患者的 NF。
