Purpose This study aimed to evaluate the validity of the Return-to-Work Self-efficacy Questionnaire (RTW-SE) in a Norwegian sample of patients with common mental disorders. The secondary aim was to provide validated cut-off scores for the RTW-SE. Methods Among patients receiving work-focused therapy (N = 626), the RTW-SE was measured pre-and post-treatment, and work status was assessed up to one-year post-treatment. The factor structure, internal consistency and construct validity were assessed. Furthermore, post-treatment cut-off scores were calculated using receiver operating characteristic (ROC) analysis for patients on sick leave at baseline (n = 314) and at the end of treatment (n = 145). The predictive ability of the suggested RTW-SE cut-off scores were investigated longitudinally. Results Exploratory principal component analysis identified a one-factor solution with high internal consistency (0.91). RTW-SE exhibited small to moderate negative correlations with measures of depression and anxiety, and was significantly different between subgroups of patients with different work status, supporting construct validity. Pre- and post-treatment RTW-SE scores significantly predicted full return to work at 3, 6 and 12 months post-treatment. ROC analysis suggested an upper cut-off score of 4.6, associated with full RTW, and lower cut-off score of 3.7, associated with partial RTW. These cut-offs showed acceptable discriminative ability and significant longitudinal predictive ability. Conclusion The RTW-SE possesses good psychometric properties and the suggested cut-off scores have significant predictive ability in a clinical setting.

目的本研究旨在评估回归工作自我效能问卷 (RTW-SE) 在挪威常见​​精神障碍患者样本中的有效性。次要目的是为 RTW-SE 提供经过验证的截止分数。方法在接受以工作为重点的治疗的患者 ( N  = 626) 中，在治疗前和治疗后测量 RTW-SE，并评估治疗后长达一年的工作状态。评估因素结构、内部一致性和结构效度。此外，使用受试者操作特征 (ROC) 分析计算基线 ( n  = 314) 和治疗结束时 ( n )病假患者的治疗后截止分数 = 145）。纵向研究了建议的 RTW-SE 截止分数的预测能力。结果探索性主成分分析确定了具有高内部一致性 (0.91) 的单因素解决方案。RTW-SE 与抑郁和焦虑的测量值呈小到中度负相关，并且在不同工作状态的患者亚组之间存在显着差异，支持结构效度。治疗前和治疗后的 RTW-SE 评分显着预测治疗后 3、6 和 12 个月完全恢复工作。ROC 分析表明，与完全 RTW 相关的上限为 4.6，与部分 RTW 相关的下限为 3.7。这些临界值显示出可接受的辨别能力和显着的纵向预测能力。结论RTW-SE 具有良好的心理测量特性，建议的临界值在临床环境中具有显着的预测能力。
