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.
