How do I use the DASS-21?

The Depression, Anxiety and Stress Scale – 21 Items (DASS-21) is a set of three self-report scales designed to measure the emotional states of depression, anxiety and stress.

Each of the three DASS-21 scales contains 7 items, divided into subscales with similar content.

  1. The depression scale assesses dysphoria, hopelessness, devaluation of life, self-deprecation, lack of interest/involvement, anhedonia and inertia.
  2. The anxiety scale assesses autonomic arousal, skeletal muscle effects, situational anxiety, and subjective experience of anxious affect. 
  3. The stress scale is sensitive to levels of chronic non-specific arousal.

To complete the DASS-21 questionnaire, please read each statement and tap the statement that most applied to you over the past week. There are no right or wrong answers. Do not spend too much time on any statement.
