AI Article Synopsis
- The 15-item Geriatric Depression Scale (GDS-15) is a tool used to identify depression in elderly people, but its structure in the Chinese version wasn't clearly defined before this study.
- Researchers analyzed the factor structure using a sample of 2,428 Chinese elders and found that a three-factor model—comprising life satisfaction, general depressive affect, and withdrawal—best represents the GDS-15.
- Additionally, they confirmed that this factor structure is consistent across genders, indicating that the scale works similarly for men and women in this population.
Article Abstract
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.
