The Depression Scale (DEPS) is a commonly used screening tool for major depression in studies investigating low back pain, yet it has not been validated for patients with back-specific problems.
To assess the psychometric properties of the DEPS in patients with degenerative spinal disease.
Six hundred and thirty-seven patients with a degenerative spinal disease completed the DEPS instrument. The Rasch Measurement Theory was applied to analyze the measurement properties of the DEPS. The main hypothesis-driven approach was whether the DEPS would meet relevant psychometric criteria for assessing depressive symptoms among patients with degenerative spinal disease.
The Mean (SD) DEPS score was 9.2 (6.6). Scale minimum or maximum points among participants were 2.4% and 0.8%, respectively. Cronbach's alpha for internal consistency was 0.92. Person Separation Index for reliability was 0.88. All items had ordered thresholds and seven of the 10 items had good item fit. Unidimensionality of the DEPS was supported (proportion of significant t-tests, 4.5%).
This study supports the validity of the DEPS for screening depressive symptoms in patients with degenerative spinal disease.
抑郁量表（DEPS）是研究腰痛时常用的一种主要抑郁症筛查工具，但尚未针对特定于背部的问题患者进行验证。
评估 DEPS 在退行性脊柱疾病患者中的心理测量特性。
637 名退行性脊柱疾病患者完成了 DEPS 量表。应用 Rasch 测量理论分析 DEPS 的测量特性。主要的假设驱动方法是 DEPS 是否符合评估退行性脊柱疾病患者抑郁症状的相关心理测量标准。
DEPS 的平均（标准差）得分为 9.2（6.6）。参与者的量表最低或最高分为 2.4%和 0.8%。内部一致性的克朗巴赫α系数为 0.92。可靠性的个体分离指数为 0.88。所有项目均具有有序阈值，其中 10 个项目中的 7 个具有良好的项目拟合度。DEPS 的单维性得到支持（显著 t 检验的比例为 4.5%）。
本研究支持 DEPS 在筛查退行性脊柱疾病患者抑郁症状方面的有效性。
