Abstract

The factor structure, reliability, and validity of the Depression Anxiety Stress Scales (DASS; S. H. Lovibond & P. F. Lovibond, 1995) and the 21-item short form of these measures (DASS-21) were examined in nonclinical volunteers (n = 49) and patients with Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) diagnoses of panic disorder (n = 67), obsessive-compulsive disorder (n = 54), social phobia (n = 74), specific phobia (n = 17), and major depressive disorder (n = 46). This study replicates previous findings indicating that the DASS distinguishes well between features of depression, physical arousal, and psychological tension and agitation and extends these observations to the DASS-21. In addition, the internal consistency and concurrent validity of the DASS and DASS-21 were in the acceptable to excellent ranges. Mean scores for the various groups were similar to those in previous research, and in the expected direction. The implications of these findings are discussed.

  • The DASS-21 has three factors, good to excellent internal consistency, and strong correlations with other measures of general distress in clinical and nonclinical samples.

    “Factor analysis of the 21-item version yields three factors and internal consistency for the subscales range from good to excellent (Antony, Bieling, Cox, Enns, & Swinson, 1998). The measure also demonstrates strong correlations with other measures of general distress in clinical (Antony et al., 1998) and nonclinical samples (Henry & Crawford, 2005).”
  • The Depression and Anxiety Stress Scale-21 has high internal consistency and concurrent validity, distinguishing well between depression, anxiety, and stress.

    “The DASS-21 demonstrates high internal consistency and concurrent validity indicating that it distinguishes well between features of depression, anxiety, and stress (Antony, Cox, Enns, Bieling, & Swinson, 1998).”
  • The DASS-21 has separate, reliable, and valid self-report scales for depression, anxiety, and stress.

    “Depression Anxiety Stress Scale – 21-item version (DASS-21; Lovibond & Lovibond, 1995) has separate, reliable and valid self-report scales for depression, anxiety (i.e., anxious arousal), and stress (i.e., general anxiety and tension) (Antony, Bieling et al., 1998).”
  • The Depression Anxiety Stress Scales-21-item version has demonstrated excellent internal consistency, and the longer 42-item version has demonstrated adequate test-retest reliability.

    “The DASS-21 has demonstrated excellent internal consistency (α from .88 to .94; Antony, Bieling, Cox, Enns, & Swinson, 1998) and the longer 42-item version has demonstrated adequate test-retest reliability (Brown, Chorpita, Korotitsch, & Barlow, 1997).”

  • The DASS-21 depression, anxiety, and stress subscales had acceptable to good internal consistency at pretreatment in the present study (αs = .86, .76, and .84, respectively).

    “Internal consistency has previously been shown to be good (α for each scale > .87; Antony, Bieling, Cox, Enns, & Swinson, 1998), and was acceptable to good at pretreatment in the present study (αs for depression, anxiety, and stress = .86, .76, and .84, respectively).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
