Abstract
The psychometric properties of the Spanish version of the Depression, Anxiety and Stress Scales (DASS), and its short form (DASS-21), were studied in 365 Spanish university students. According to the confirmatory factor analysis of the DASS, none of the models (3 factors, a second-order factor underlying the three factors) had an acceptable fit. With regard to the DASS-21 the three-factor model had the best fit; this fit can be said to be acceptable but not good enough. Correlations with other questionnaires of anxiety, depression and positive/negative affect revealed a satisfactory convergent validity and an acceptable divergent validity. The discriminant validity was satisfactory, although the anxiety scale did not distinguish between anxious (n= 23) and depressed (n= 12) patients.
