背景资料：很少有研究评估15项老年抑郁量表（GDS-15）在不同年龄，种族和社区社会服务的老年用户的合并症的异质性人群的有效性。目的：评估GDS-15的标准有效性和可靠性及其在不同性别、年龄组、种族和不同合并症的社区老年人和养老院居民中的等效性。方法：验证样本的非痴呆4253老年人（年龄60岁），谁经常使用社区为基础的护理角落，老年活动中心，日托中心，庇护之家和疗养院进行了采访，使用GDS-15。采用结构化临床访谈法（SCID）对抑郁症（MDD）进行诊断。结果：总的敏感性和特异性分别为0.97和0.95（曲线下面积，AUC为0.98）。总体Cronbach’s α为0.80，两周内的重测信度为0.83，评定者间信度为0.94（组内）和0.99（Cohen’s Kappa）。尽管GDS-15中的一些项目似乎因性别、年龄和种族而存在偏倚，但在4/5临界值时，不同年龄、性别、种族和合并症之间的测试性能无临床显著差异。结论：GDS-15是社区和社会服务环境中不同年龄、性别、种族和慢性病状态的MDD的可靠和有效筛查。
Background: Few studies have evaluated the validation of 15-item Geriatric Depression Scale (GDS-15) in a heterogeneous population with different age, ethnicity and comorbidities of elderly users of social services in the community. Aims: To assess the criterion validity and reliability of the GDS-15 and its equivalence across different gender, age groups, ethnicity and different comorbidities in community living elderly and nursing homes residents. Method: A validation sample of non-demented 4253 elderly (age 60 years), who regularly use community based care corner, senior activity center, day care center, sheltered homes and nursing homes were interviewed using the GDS-15. Structured clinical interview (SCID) was used to make DSM-IV diagnosis of major depressive disorder (MDD). Results: The overall sensitivity and specificity were 0.97 and 0.95, respectively (area under curve, AUC was 0.98). The overall Cronbach's alpha was 0.80, and intraclass coefficient of test--retest reliability over 2 weeks was 0.83 and inter-rater reliability was 0.94 (intra-class) and 0.99 (Cohen's kappa). Although some items in the GDS-15 appeared to be biased by gender, age and ethnicity, there were no clinically significant differences in test performance among different age, gender, ethnicity and comorbidities at cutoff of 4/5. Conclusions: The GDS-15 was a reliable and valid screening for MDD across different age, gender, ethnicity and chronic illness status in the community and social service setting.
