: The scale moves beyond a binary view of distress by adding "Stress" as a third distinct factor.
The internal consistency of the DASS-21 has been widely examined, with most studies reporting good reliability for the total scale (α = 0.88-0.93) and subscales (α = 0.70-0.88; Lovibond & Lovibond, 1995). Test-retest reliability has also been reported to be good, with coefficients ranging from 0.71 to 0.91 over a period of 2-4 weeks (Lovibond & Lovibond, 1995).
