- Abstract
- The Depression Anxiety and Stress Scales-21 (DASS-21) involves a simple structure firstorder three-factor oblique model, with factors for depression, anxiety, and stress. Recently, concerns have been raised over the value of using confirmatory factor analysis (CFA) for studying the factor structure of scales in general. However, such concerns can be circumvented using exploratory structural equation modeling (ESEM). Consequently, the present study used CFA and ESEM with target rotation to examine the factor structure of the DASS21 among an adult community. It compared first-order CFA, ESEM with target rotation, bifactor CFA (BCFA), and bi-factor BESEM with target rotation model with group/specific factors for depression, anxiety, and stress. A total of 738 adults (males = 374, and females =364; M = 25.29 years; SD = 7.61 years) completed the DASS-21. While all models examined showed good global fit values, one or more of the group/specific factors in the BCFA, ESEM with target rotation and BESEM with target rotation models were poorly defined. As the firstorder CFA model was most parsimonious, with well-defined factors that were also supported in terms of their reliabilities and validities, this model was selected as the preferred DASS21 model. The implications of the findings for use and revision of the DASS-21 are discussed
