A Cross-Sectional Network Analysis Study Applied to the Depression Anxiety Stress Scale-21 (DASS-21): A New Factor Revealed

Abstract

Conclusion: The classic structure of the DASS-21 (three factors) was replicated, but a four-factor model proved to be the one with the best statistical indices for nonclinical sample, providing new insight into the internal structure of this scale. In addition, there was factorial invariance between the groups compared. Implications for the use of the new structure are discussed.
