Abstract: The main objective of the present studywas to examine the psychometric properties of the
Spanish version of the Depression Anxiety Stress
Scales, in its 21-item version (DASS-21), in a sample
of Spanish college students. The sample was
composed of 759 participants (532 females), with a
mean age of 19.63 years (SD =2.03). Results showed
that the levels of internal consistency for the subscales
of the DASS-21 ranged from 0.73 to 0.81.
With respect to the internal structure of the DASS-
21, the confirmatory factor analysis indicated that
the three-factor model, composed by the Depression,
Anxiety and Stress factors, was the one with the best
fit indices in comparison to the remaining competent
models. No item in the DASS-21 presented differences
in functioning due to gender of participants.
Likewise, statistically significant differences were
found due to gender between mean scores in the
Stress subscale. Consistent with previous literature,
the DASS-21 seems to be a useful and brief assessment
instrument, of rapid administration and adequate
psychometric properties for the assessment of
depression, anxiety and stress in nonclinical populations.
