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.

The depression scale assesses dysphoria, hopelessness, devaluation of life, self-deprecation, lack of interest/involvement, anhedonia and inertia.

The anxiety scale assesses autonomic arousal, skeletal muscle effects, situational anxiety, and subjective experience of anxious affect.

The stress scale is sensitive to levels of chronic nonspecific arousal. It assesses difficulty relaxing, nervous arousal, and being easily upset/agitated, irritable/over-reactive and impatient.

Scores for depression, anxiety and stress are calculated by summing the scores for the relevant items.

The DASS-21 is a set of brief questions designed to measure your emotional state prior to your session. It's a helpful tool for our psychologists and although it is optional, we recommend you complete it prior to your upcoming session, as it can improve the outcome of your session. See our article How Do I Complete The Dass21 Questionnaire?

To complete the DASS-21 questionnaire simply log into your account on the My Mirror website and you'll find a link to the questionnaire with the details of your upcoming session.

Note: the questionnaire will only be accessible from 45 minutes prior to your session and will close 10 minutes prior to the start of your session.

Prior to your session, you'll receive an SMS reminder to complete the DASS-21 questionnaire.
