The Calgary Depression Scale (CDS) is a nine item structured interview scale, in which each item has a four point measure, each point anchored by descriptors. The scale has been specifically developed to assess depression in schizophrenics. This article describes the testing of the reliability and validity of the CDS. The scale is assessed and compared to three established measures, the Hamilton Depression Rating Scale (HDRS) the Beck Depression Inventory (BDI) and a depression measure derived from the Brief Psychiatric Rating Scale (BPRS). Confirmatory factor analysis demonstrated that the CDS is unidimensional, measuring the same construct in both in- and outpatients. The scale has high internal consistency, significant strong correlations with scores on the Hamilton, Beck and BPRS depression measures, and the presence of a major depressive episode. All items of the CDS significantly discriminate between the presence and absence of a major depressive episode. It is concluded that the CDS is a parsimonious reliable scale which is suitable for assessing depression across both the acute and residual stages of schizophrenia.
卡尔加里抑郁量表（CDS）是一个包含九个条目的结构化访谈量表，其中每个条目有四点度量，每个点由描述语锚定。该量表是专门为评估精神分裂症患者的抑郁而开发的。本文描述了CDS的信度和效度测试。该量表经过评估，并与三个既定量表进行比较，即汉密尔顿抑郁评定量表（HDRS）、贝克抑郁量表（BDI）以及从简明精神病评定量表（BPRS）衍生出的抑郁量表。验证性因素分析表明，CDS是单维的，在门诊患者和住院患者中测量的是相同的结构。该量表具有较高的内部一致性，与汉密尔顿、贝克和BPRS抑郁量表的得分以及重度抑郁发作的存在有显著的强相关性。CDS的所有条目在重度抑郁发作的存在与否之间有显著差异。结论是，CDS是一个简洁可靠的量表，适用于评估精神分裂症急性期和残留期的抑郁。
