Overview of DASS-21

The DASS-21 is a self-report instrument designed to measure three negative emotional states: depression, anxiety, and stress. It's a shorter version of the original DASS-42. The scale consists of 21 items, divided into three subscales: Depression (7 items), Anxiety (7 items), and Stress (7 items). Each item is rated on a 4-point severity scale, ranging from 0 (did not apply to me at all) to 3 (applied to me very much, or most of the time).

Scoring
Each item uses the standard 0–3 severity scale. Domain scores are summed, then converted to T‑scores normed on a general population sample (N = 12,000). Percentile ranks and severity labels (Normal, Mild, Moderate, Severe, Extremely Severe) are provided separately for each of the 30 subscales. DASS-280
