摘要
The objective of this study was to evaluate the reliability and validity of the Geriatric Depression Scale in its 15-item version (GDS-15) in Mexican older adults. Participants included 1178 older adults between the ages of 60 and 94 (M = 69.16, SD = 7.69); 53.9% were women and 55.8% were married or with a partner. They completed the GDS-15, a subjective well-being scale, and a quality-of-life questionnaire. A Kuder-Richardson coefficient of .80 was obtained, which indicates an acceptable internal consistency of the GDS-15, as well as evidence of divergent validity with significant correlations of -.783 with subjective well-being and -.569 with quality of life, in addition to concurrent validity when discriminating between participants with low scores from those with high scores of depressive symptoms. The need for a simple screening tool such as the GDS-15 that helps in the identification of depressive symptoms in Mexican older adults is underlined.
