Depression, Anxiety and Stress Scale - 21 Items

The Depression, Anxiety and Stress Scale - 21 Items (DASS21) is short version of the Depression, Anxiety and Stress Scale (DASS). The DASS is a set of three self-report scales designed to measure the negative emotional states of depression, anxiety and stress. The DASS was constructed not merely as another set of scales to measure conventionally defined emotional states, but to further the process of defining, understanding, and measuring the ubiquitous and clinically significant emotional states usually described as depression, anxiety and stress. The DASS should thus meet the requirements of both researchers and scientist-professional clinicians.
