The Depression, Anxiety and Stress Scale (DASS-21) is a self-report questionnaire designed to measure three related negative emotional states of depression, anxiety and tension/stress.

The DASS-21 was developed at the University of New South Wales (Australia) and published by Lovibond, S.H. & Lovibond, P.F. (1995).  Manual for the Depression Anxiety Stress Scales. (2nd. Ed.)  Sydney: Psychology Foundation.

Depression score: assesses dysphoria, hopelessness, devaluation of life, self-deprecation, lack of interest / involvement, anhedonia and inertia.

Anxiety score: assesses autonomic arousal, skeletal muscle effects, situational anxiety, and subjective experience of anxious affect.

Stress score: assesses difficulty relaxing, nervous arousal, and being easily upset or agitated, irritable or over-reactive and impatient.

Disclaimer: Scores on the DASS-21 do not indicate a diagnosis. They simply provide a measure of severity based on the three assessed domains. To determine any potential diagnosis, discuss your results with your doctor or a qualified mental health provider.
