The Calgary Depression Scale for Schizophrenia (CDSS) is a nine-item structured interview scale developed by Addington et al. to assess depression in schizophrenics. This paper describes the testing of the reliability and validity of the French version of the CDSS in a population of 70 schizophrenic patients. The validity of the CDSS as a measure of depression was confirmed; a single factor accounted for 41% of the variance of the nine items. The total score on the CDSS was strongly correlated with those on the Montgomery-Asberg Depression Rating Scale (MADRS), the Hamilton Depression Rating Scale (HDRS) and also the G6 item (depression) of the Positive and Negative Syndrome Scale (PANSS). The correlation with the Psychomotor Retardation Scale (ERD) total score was much less significant and was better with the 'subjective' subscore. The internal consistency was good, with a Cronbach's alpha of 0.79. A high level of inter-rater reliability was observed (weighted kappa values were >0.75 in all cases). The CDSS has a lower stability over time than other depression scales. It is a simple, quick and reliable scale for assessing depression in schizophrenic populations.
《卡尔加里精神分裂症抑郁量表》（CDSS）是由阿丁顿等人编制的一个包含九个条目的结构化访谈量表，用于评估精神分裂症患者的抑郁状况。本文描述了在70名精神分裂症患者群体中对CDSS法语版的信效度测试。CDSS作为抑郁测量工具的效度得到了证实；一个单一因素解释了九个条目的41%的方差。CDSS总分与蒙哥马利-艾斯伯格抑郁评定量表（MADRS）、汉密尔顿抑郁评定量表（HDRS）以及阳性和阴性症状量表（PANSS）的G6项（抑郁）得分显著相关。与精神运动迟缓量表（ERD）总分的相关性则不太显著，与“主观”子得分的相关性更好。内部一致性良好，克朗巴哈系数为0.79。观察到评分者间信度较高（所有情况下加权kappa值均>0.75）。CDSS随时间的稳定性低于其他抑郁量表。它是评估精神分裂症群体抑郁状况的一个简单、快速且可靠的量表。
