Key result
Confirmatory factor analysis of the CES-D in 685 rheumatoid arthritis patients showed that the correlated 4-factor model and the second-order 4-factor model were the best fitting models.

Subscale scores may better inform depressive symptom assessment in RA than total CES-D; extends 4-factor validation to this population.
Observational (n=685)
What is the factor structure of the CES-D in patients with rheumatoid arthritis?
The 4-factor structure of the CES-D is replicated in RA patients, suggesting a single summary score may not be the most informative index due to criterion contamination.
Rhee et al. (1999) conducted an observational in Rheumatoid arthritis (n=685). Center for Epidemiologic Studies Depression Scale (CES-D) was evaluated on Factor structure of the CES-D. Confirmatory factor analysis of the CES-D in 685 rheumatoid arthritis patients showed that the correlated 4-factor model and the second-order 4-factor model were the best fitting models.
