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.

本研究的目的是评估 15 项版本的老年抑郁量表 (GDS-15) 在墨西哥老年人中的信度和效度。参与者包括 1178 名年龄在 60 岁至 94 岁之间的老年人（ M = 69.16，SD = 7.69）； 53.9% 为女性，55.8% 已婚或有伴侣。他们完成了 GDS-15、主观幸福感量表和生活质量调查问卷。获得的 Kuder-Richardson 系数为 0.80，这表明 GDS-15 具有可接受的内部一致性，并且存在不同有效性的证据，与主观幸福感显着相关性为 -.783，与生活质量显着相关性为 -.569 ，除了区分低分参与者和高分抑郁症状参与者时的并发有效性。强调需要一种简单的筛查工具（例如 GDS-15）来帮助识别墨西哥老年人的抑郁症状。
