其他摘要：Objective: To determine the internal consistency, factor structure and construct reliability of the Yesavage Geriatric Depression Scale (GDS-15) among older people attending community centers in Cartagena (Colombia). Materials and method: Validation study of a screening scale without a gold standard. A group of 185 adults participated in this research. Ages were between 65 and 95 years (Mean = 75.6, SD=6.9); and 57.3% were women. Internal consistency was determined by Kuder-Richardson´s formula 20, factor structure was explored by factor analysis with principal component method, and construct reliability was computed by Anderson-Gerbing´s formula. Results: Internal consistency was 0,783 and the factor solution showed two factors (depressed mood and life enjoy) that explained 37.3% of the variance, and construct reliability was 0,700. Conclusions: The GDS-15 showed acceptable internal consistency and construct reliability. However, its two-dimensional factor structure is not satisfactory. It is possible that the GDS- 15 exhibits low ability to identify depressive episodes in elders with low scholarship.
