The DASS167 is a self-report questionnaire that consists of 167 items, divided into three subscales: Depression, Anxiety, and Stress. The tool is designed to assess the severity of symptoms of anxiety, depression, and stress in individuals, providing a comprehensive picture of their mental health status. The DASS167 is based on the well-established DASS21 questionnaire, which has been widely used in research and clinical practice for over two decades.
