Abstract

Introduction

In psychotherapy, having a reliable tracking tool is vital for effective treatment. We have validated the Danish version of the ‘Overall Depression Severity and Impairment Scale’ (ODSIS), which is used in the Unified Protocol for Emotional Disorders (UP) and other cognitive behavioural therapies. This five-item self-rating scale is expected to correspond closely to the gold-standard Beck Depression Inventory-II (BDI-II), but also to self-rating scales addressing daily functioning and well-being.

Methods

Internal consistency is assessed using Cronbach's alpha and McDonald's omega. Criterion validity is explored through Pearson's correlation coefficient with BDI-II, the Work and Social Adjustment Scale (WSAS), the Five-Item World Health Organization Well-Being Index (WHO-5) and scatter plots, and an optimal cut-off score is determined using a receiver operating characteristic curve. The study included 340 respondents: 234 from a recent clinical trial, 56 psychiatric patients from inpatient/outpatient units and 50 healthy volunteers.

Results

ODSIS demonstrates strong internal consistency (Cronbach's alpha: 0.887–0.956, McDonald's omega: 0.888–0.957). Correlations with BDI-II, WSAS and WHO-5 highlight its strong criterion validity (BDI-II: 0.847, WSAS: 0.751, WHO-5: 0.771). The optimal cut-off score (> 7.5) for detecting depression shows great sensitivity (0.862) and specificity (0.731).

Conclusion

The Danish version of ODSIS proves to be a reliable instrument for quantification of a combination of depression level and functional impairment from the symptoms. Its high correlation with established BDI-II makes it a brief and handy tool for repeated measurement in clinical and research settings.

丹麦版整体抑郁严重程度和功能损害量表（ODSIS）的验证：评估抑郁症状和功能障碍的可靠工具

引言在心理治疗中，拥有可靠的跟踪工具对有效治疗至关重要。我们对丹麦版 "整体抑郁严重程度和损害量表"（ODSIS）进行了验证，该量表用于情绪障碍统一方案（UP）和其他认知行为疗法。该量表由五个项目组成，不仅与黄金标准贝克抑郁量表-II（BDI-II）密切相关，还与针对日常功能和幸福感的自评量表密切相关。方法采用 Cronbach's alpha 和 McDonald's omega 评估内部一致性。通过与 BDI-II、工作和社会适应量表（WSAS）、世界卫生组织幸福指数五项（WHO-5）的皮尔逊相关系数和散点图来探讨标准效度，并利用接收者操作特征曲线确定最佳临界分数。该研究包括 340 名受访者：其中 234 人来自最近的一项临床试验，56 人来自住院/门诊部的精神病患者，50 人是健康志愿者。结果 ODSIS 显示出很强的内部一致性（克朗巴赫α：0.887-0.956，麦克唐纳Ω：0.888-0.957）。与 BDI-II、WSAS 和 WHO-5 的相关性突显了其强大的标准效度（BDI-II：0.847；WSAS：0.751；WHO-5：0.771）。检测抑郁症的最佳截断分数（> 7.5）显示出极高的灵敏度（0.862）和特异性（0.731）。结论丹麦版 ODSIS 被证明是一种可靠的工具，可用于量化抑郁程度和症状造成的功能障碍。它与已有的 BDI-II 高度相关，因此是一种简便易行的工具，可在临床和研究环境中重复测量。

期刊介绍： Clinical Psychology & Psychotherapy aims to keep clinical psychologists and psychotherapists up to date with new developments in their fields. The Journal will provide an integrative impetus both between theory and practice and between different orientations within clinical psychology and psychotherapy. Clinical Psychology & Psychotherapy will be a forum in which practitioners can present their wealth of expertise and innovations in order to make these available to a wider audience. Equally, the Journal will contain reports from researchers who want to address a larger clinical audience with clinically relevant issues and clinically valid research.
