目的采用脑卒中后抑郁自评量表（PSDS）评估脑卒中患者抑郁症状的严重程度，具有较好的信效度。本研究旨在重新测试不同类型脑卒中后抑郁（PSD）的PSD的心理测量特性。材料与方法共招募170例脑卒中患者。根据各自的诊断标准分别诊断为PSD症状障碍（PSDSD）和PSD障碍（PSDD）患者82例和25例。采用抑郁量表（PSDS）和9项患者健康问卷（PHQ-9）评估抑郁的严重程度。采用Cronbach α、Spearman秩系数和独立样本t检验检验信度、内部一致性和区分效度。然后分别用受试者工作特征曲线和约登指数对不同亚型PSD患者进行性能评价和截断值。结果PSDS的Cronbach α为0.857，信度较好。PSDS与PHQ-9的Spearman相关系数为0.942 （P<0.001）。抑郁症患者与非抑郁症患者的区别效度差异有统计学意义（p <0.001）。5/24和10/24分别为PSDSD和PSDD患者的临界值。结论spsds是一种有用的筛选工具，具有良好的心理测量特性，可用于估计不同亚型的PSD患者。
ObjectiveA self-rating post stroke depression scale (PSDS) showed a good reliability and validity to assess severity of depressive symptoms among stroke patients. This study aimed to retest the psychometric properties of PSDS in different types of post-stroke depression (PSD).Materials and methodsA total of 170 stroke patients were recruited in the study. 82 and 25 patients were respectively diagnosed as PSD symptoms disorder (PSDSD) and PSD disorder (PSDD) patients according to their respective diagnostic criteria. The PSDS and the 9-item Patient Health Questionnaire (PHQ-9) were used to assess the severity of depression. Cronbach α, Spearman rank coefficient and independent sample t-test were conducted to examine reliability, internal consistency and discriminate validity. Then the receiver operating characteristic curve and Youden index were used to performance evaluation and cut-off value respectively in different subtypes of PSD patients.ResultsThe Cronbach α of PSDS was 0.857, indicting a good reliability. The Spearman correlation coefficient between PSDS and PHQ-9 was 0.942 (P<0.001). The discriminate validity displayed significant difference between PSDSD as well as PSDD and no depression patients (allP<0.001). 5/24 and 10/24 were the cut-off value for PSDSD and PSDD patients.ConclusionsPSDS is a useful screen tool with an acceptable psychometric properties for estimation of different subtypes of PSD patients.
