The DASS is a 42-item self report instrument designed to measure the three related negative emotional states of depression, anxiety and tension/stress.

How do I get permission to use the DASS?

The DASS questionnaire is public domain, and so permission is not needed to use it. The DASS questionnaires and scoring key may be downloaded from the DASS website and copied without restriction (go to: http://www2.psy.unsw.edu.au/Groups/Dass/down.htm).

The DASS questionnaires and scoring key may also be distributed, published or made available electronically, with the restrictions that:

• the scales are not modified,
• the scales are not sold for profit,
• the intended audience is researchers or health professionals rather than end users, and
• reference is included to the DASS website: www.psy.unsw.edu.au/dass/
