DASS-21: Depression Anxiety Stress Scales test

The DASS-21 is a widely used and scientifically validated self-report questionnaire designed to measure the severity of three negative emotional states: depression, anxiety, and stress.

The genius of the DASS-21 lies in its structure. It separates the often-jumbled feelings of negative emotion into three distinct categories, or subscales: Depression, Anxiety, and Stress.

The DASS-21 is scientifically validated. Click on the link below to see some scientific references:
