The Depression and Somatic Symptoms Scale (DSSS), which is a free scale that includes a depression subscale (DS) and a somatic subscale (SS), was developed to evaluate depression and somatic symptoms simultaneously. This study aimed to examine the reliability and validity of the DSSS among patients with chronic low back pain (CLBP).
Two-hundred and twenty-five patients with CLBP were enrolled. Psychiatric diagnoses were made based on the Structured Clinical Interview for -IV-Text Revision. The DSSS, Oswestry Disability Index, Hospital Anxiety and Depression Scale (HADS), and Short Form 36 (SF-36) were administered. Cronbach's alpha was used to test internal consistency. Receiver operating characteristic (ROC) analysis was used to identify cutoff scores for a major depressive episode (MDE).
Subjects with an MDE (N=21) had greater severities of depression, anxiety, somatic symptoms, and disability as compared with those without an MDE. The Cronbach's alpha values of the DS and SS were 0.90 and 0.83, respectively. The DS and SS were significantly correlated with the Oswestry Disability Index, the HADS, and the SF-36 subscales. The DS had the greatest area under the receiver operating characteristic curve (0.96) as compared with the SS and the HADS subscales. The cutoff score for an MDE was a DS score ≥15 (sensitivity and specificity: 100% and 88.7%, respectively).
The DSSS subscales were of acceptable reliability and validity. The DS can be used as a tool for evaluating the severity of depression and detecting an MDE in patients with CLBP.
抑郁与躯体症状量表（DSSS）是一种免费量表，包含抑郁分量表（DS）和躯体分量表（SS），用于同时评估抑郁和躯体症状。本研究旨在检验DSSS在慢性下腰痛（CLBP）患者中的信效度。
招募了225例CLBP患者。根据《精神障碍诊断与统计手册》第四版文本修订版的结构化临床访谈进行精神疾病诊断。使用了DSSS、奥斯威斯利功能障碍指数、医院焦虑抑郁量表（HADS）和简明健康状况调查量表（SF - 36）。采用克朗巴哈系数检验内部一致性。采用受试者工作特征（ROC）分析确定重度抑郁发作（MDE）的临界值。
与无MDE的受试者相比，患有MDE的受试者（N = 21）在抑郁、焦虑、躯体症状和功能障碍方面的严重程度更高。DS和SS的克朗巴哈系数分别为0.90和0.83。DS和SS与奥斯威斯利功能障碍指数、HADS及SF - 36分量表显著相关。与SS和HADS分量表相比，DS在受试者工作特征曲线下的面积最大（0.96）。MDE的临界值为DS得分≥15（敏感性和特异性分别为100%和88.7%）。
DSSS分量表具有可接受的信效度。DS可作为评估CLBP患者抑郁严重程度和检测MDE的工具。
