The 15-item Geriatric Depression Scale (GDS-15) is widely used to screen depression among elders. But the factor structure of the Chinese version GDS-15 remains unclear. This study was conducted to determine the best-fit factor structure of GDS-15 and to assess measurement invariance across gender groups in a sample of Chinese elders recruited from Mainland China (final sample = 2428). The best-fit factor structure was examined by confirmatory factor analysis (CFA). Multigroup CFA was utilized to test the measurement invariance across genders of the factor structure. The results of CFA revealed that a three-factor model, including life satisfaction (four items), general depressive affect (seven items), and withdrawal (three items), fits the structure of the GDS-15 best. Measurement invariance across genders was supported, fully assuming different degrees of invariance.
15项老年抑郁量表（GDS - 15）被广泛用于筛查老年人的抑郁症。但中文版GDS - 15的因子结构仍不明确。本研究旨在确定GDS - 15的最佳拟合因子结构，并评估从中国大陆招募的中国老年人样本中不同性别群体的测量不变性（最终样本 = 2428）。通过验证性因子分析（CFA）检验最佳拟合因子结构。采用多组CFA来检验因子结构在不同性别间的测量不变性。CFA结果显示，一个三因子模型，包括生活满意度（4个项目）、一般抑郁情绪（7个项目）和退缩（3个项目），最适合GDS - 15的结构。支持不同性别间的测量不变性，完全假设了不同程度的不变性。
