Depression Rating Scale (DRS) is one of the clinical outcome measures of the International Resident Assessment Instrument (interRAI) assessment. The primary aim of this study is to investigate the diagnostic accuracy and concurrent validity of the 3-day assessment window version of the DRS.
The performance of DRS was compared with a gold standard clinical diagnosis of depression in 92 patients (age ≥65) who had interRAI version 9.1 Home Care assessment completed within 30 days of discharge from psychogeriatric inpatient care or memory clinic assessment.
The DRS had poor diagnostic accuracy for depression diagnosis with an area under the curve of 0.68 (95% confidence interval [CI] = 0.57-0.77). The DRS score had a poor to moderate correlation with the Health of the Nation Outcome Scale 65+ depression item score ( r = 0.30, 95% CI = 0.09-0.48, P = .006).
This study and the existing literature raise concerns that the DRS is not an adequate measure of depression.
抑郁评定量表（DRS）是国际居民评估工具（interRAI）评估的临床结局指标之一。本研究的主要目的是调查DRS三日评估窗口版本的诊断准确性和同时效度。
将92名年龄≥65岁的患者的DRS表现与抑郁症的金标准临床诊断进行比较，这些患者在从老年精神科住院护理或记忆门诊评估出院后30天内完成了interRAI 9.1家庭护理评估。
DRS对抑郁症诊断的诊断准确性较差，曲线下面积为0.68（95%置信区间[CI]=0.57-0.77）。DRS评分与《国家健康结局量表65岁及以上》抑郁项目评分的相关性较差至中等（r=0.30，95%CI=0.09-0.48，P=.006）。
本研究及现有文献引发了对DRS并非抑郁症充分测量指标的担忧。
