Background: In Vietnam, there has been, currently, no standardized tool for depression assessment for people with dementia (PWD). Cornell Scale for Depression in Dementia (CSDD) is a widely studied and used scale for PWD worldwide. Objectives: The aim of this study was to standardize the Vietnamese version of the CSDD (V-CSDD) in depression assessment in PWD through reliability and validity examination. Methods: V-CSDD was rated in terms of reliability and validity with gold standard regarding “major depressive episode” and “major depressive-like episode” of DSM-5. Cronbach’s α, ICC, exploratory factor analysis (EFA), and receiver operating characteristic analysis were performed. Results: V-CSDD was found to have a high internal consistency reliability (Cronbach’s α = 0.80), inter-rater reliability at sound ranking (ICC = 0.89; 95% CI = 0.81–0.94), maximum cut-off mark of 13 (sensitivity = 70%, specificity = 92%), and EFA, which suggested that V-CSDD may comprise 5 factors. Conclusions: Results indicate the V-CSDD to be a reliable and valid assessment and to be beneficial in classifying and diagnosing depression in dementia outpatients in clinical contexts.

越南版康奈尔痴呆症抑郁量表在门诊记忆诊所：信度和效度研究

背景：在越南，目前还没有针对痴呆症患者 (PWD) 的抑郁症评估的标准化工具。康奈尔痴呆症抑郁量表 (CSDD) 是一种在全球范围内广泛研究和使用的 PWD 量表。目的：本研究的目的是通过信度和效度检验规范越南版 CSDD (V-CSDD) 在 PWD 抑郁评估中的应用。方法： V-CSDD 采用金标准对 DSM-5 的“重度抑郁发作”和“重度抑郁样发作”进行信度和效度评估。进行了 Cronbach's α、ICC、探索性因素分析 (EFA) 和受试者工作特征分析。结果：发现 V-CSDD 具有较高的内部一致性信度（Cronbach's α = 0.80），评级时的评分者间信度（ICC = 0.89；95% CI = 0.81-0.94），最大截止标记为 13（灵敏度 = 70%，特异性 = 92%）和 EFA，这表明 V-CSDD 可能包含 5 个因素。结论：结果表明，V-CSDD 是一种可靠和有效的评估方法，有利于在临床背景下对痴呆门诊患者的抑郁症进行分类和诊断。
