The aim of the present study was to determine the reliability and validity of the Chinese version of the Calgary Depression Scale for Schizophrenia (CDSS-C) in schizophrenia patients.
One hundred and one inpatients from four mental health units who met DSM-IV criteria for schizophrenia were enrolled. The Positive and Negative Syndrome Scale (PANSS), Hamilton Depression Rating Scale (HDRS-24), Simpson-Augus Rating Scale (SAS), and Barnes Acathisia Rating Scale (BARS) were administered by the first rater, whereas the CDSS-C was assessed by a second independent rater.
The internal consistency (Cronbach's alpha = 0.80) and the inter-rater reliability (kappa coefficient >0.79) were good. The test-retest reliability was high (r = 0.927). The scale had good construct validity, with statistically significant correlations with the HDRS-24, G6 item (depression) of PANSS, and significant weak correlations with the general psychopathology subscale of PANSS. The CDSS-C showed no correlation with the positive and negative subscale of PANSS, the SAS and the BARS.
The Chinese version of CDSS is a valid and reliable instrument for the assessment of depression in schizophrenia.
本研究旨在确定中文版精神分裂症卡尔加里抑郁量表（CDSS-C）在精神分裂症患者中的信度和效度。
招募了来自四个精神卫生机构的101名符合DSM-IV精神分裂症标准的住院患者。由第一位评估者使用阳性与阴性症状量表（PANSS）、汉密尔顿抑郁评定量表（HDRS-24）、辛普森-奥古斯评定量表（SAS）和巴恩斯静坐不能评定量表（BARS），而CDSS-C由第二位独立评估者进行评估。
内部一致性（Cronbach's alpha = 0.80）和评估者间信度（kappa系数>0.79）良好。重测信度较高（r = 0.927）。该量表具有良好的结构效度，与HDRS-24、PANSS的G6项（抑郁）有统计学显著相关性，与PANSS的一般精神病理学分量表有显著弱相关性。CDSS-C与PANSS的阳性和阴性分量表、SAS及BARS均无相关性。
中文版CDSS是评估精神分裂症患者抑郁状况的有效且可靠的工具。
