Abstract

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 > or = 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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
