Dass-243
The DASS-243 is based on the tripartite model of emotional disturbance, which posits that depression, anxiety, and stress are distinct but related constructs. This model suggests that each of these conditions has unique characteristics and symptoms, but they can also co-occur and share common underlying factors. The DASS-243 was designed to capture the nuances of these interrelated constructs and provide a comprehensive assessment of an individual's mental health.
