What Is the DASS-21?

The DASS-21 is the short form of the 42-item DASS developed by Lovibond and Lovibond. It has seven items per subscale, rating how much each statement applied to you over the past week. You receive three scores:

• Depression: low mood, hopelessness, loss of interest
• Anxiety: autonomic arousal, situational anxiety, subjective fear
• Stress: tension, irritability, difficulty relaxing

DASS-21 is a screening tool, not a psychiatric diagnosis.
