Key result
Confirmatory factor analysis of the Hospital Anxiety and Depression Scale in 1,793 patients with coronary heart disease showed that three-factor models offered a superior fit to two-factor models.
Why the study?
What is the underlying factor structure of the Hospital Anxiety and Depression Scale (HADS) in patients with coronary heart disease?
Cross-Sectional (n=1,793)
Yes
What is the underlying factor structure of the Hospital Anxiety and Depression Scale (HADS) in patients with coronary heart disease?
The HADS instrument in CHD patients is better represented by a three-factor model rather than the originally proposed two-factor model, suggesting more precise scales should be used in outcome studies to reduce measurement errors.
No takes yet. Share an insight, caveat, or question.
Supports cautious HADS interpretation in CHD; leaves open whether three-factor scoring improves outcome prediction.
Martin et al. (2008) conducted a cross-sectional in coronary heart disease (n=1,793). Hospital Anxiety and Depression Scale (HADS) three-factor model vs. Two-factor model was evaluated on Factor structure fit. Confirmatory factor analysis of the Hospital Anxiety and Depression Scale in 1,793 patients with coronary heart disease showed that three-factor models offered a superior fit to two-factor models.
