老年抑郁量表中淡漠分量表的测量学指标研究

Measurement index of the Geriatric Depression Scale-3-Apathy Subscale

目的以淡漠评定量表医护人员版(AES-C)为参考,评估老年抑郁量表中淡漠分量表(GDS-3A)测量老年淡漠的灵敏度和特异度。方法采用便利抽样法,选取2019年5月—2020年10月解放军总医院和北京市东城区和平里社区卫生服务中心门诊就诊的475名老年人为研究对象,采用简化版老年抑郁量表(GDS-15)、老年抑郁量表中抑郁分量表(GDS-12D)、AES-C进行调查,使用相关性分析、ROC曲线对比分析法进行统计分析。结果GDS-3A选取2分为界值时,对应的灵敏度、特异度分别为70.99%、87.54%,ROC曲线下面积为0.77。GDS-3A得分与AES-C(r=0.46,P<0.001)、GDS-12D(r=0.67,P<0.001)、GDS-15(r=0.87,P<0.001)得分均呈正相关。结论GDS-3A具有较高的灵敏度和特异度,可作为大规模流行病学调查或社区老年人淡漠的筛查工具。

Objective To evaluate the sensitivity and specificity of the Geriatric Depression Scale3-Apathy Subscale(GDS-3A)in the assessment of apathy in the aged by taking the Apathy Evaluation ScaleClinician(AES-C)as a reference.Methods From May 2019 to October 2020,convenience sampling was used to select 475 elderly patients who attended the Outpatient Department of the People's Liberation Army General Hospital and Hepingli Community Health Service Center in Dongcheng District,Beijing as the research object.The 15-item Geriatric Depression Scale(GDS-15),GDS-12-Depression Subscale(GDS-12D)and the AES-C were used for investigation.The statistical analysis was conducted by using the correlation analysis and receiver operating characteristic(ROC)curve comparison analysis.Results When GDS-3A selected 2 points as the boundary value,the corresponding sensitivity and specificity were 70.99%and 87.54%,respectively,and the area under the ROC curve was 0.77.GDS-3A was positively correlated with AES-C(r=0.46,P<0.001),GDS12D(r=0.67,P<0.001),and GDS-15(r=0.87,P<0.001).Conclusions GDS-3A has high sensitivity and specificity,and can be used as a screening tool for large-scale epidemiological investigations or community elderly apathy manifestations.
