Psychometric evaluation of the depression anxiety stress scales-21 (DASS-21) in a Serbian student sample
2014
The purpose of the current research was to examine the psychometric
properties of the Depression Anxiety Stress Scales-21 (DASS-21) in a student
sample. In Study 1 (N = 1374), a confirmatory factor analysis was used to
evaluate construct validity of the DASS- 21. The stability of the DASS-21
structure over time (5-month follow-up, N = 693) was investigated also in
Study 1. In Study 2, associations with measures of depression, anxiety,
stress, affect, life satisfaction and general distress were examined to
assess the convergent validity of the DASS-21. The results suggested that the
DASS-21 was reliable and valid measure of unpleasant emotional states. The
model with optimal fit consisted of general factor of negative affect plus
three specific factors of depression, anxiety and stress. [Projekat
