This self-report measure assesses current symptoms of depression, anxiety, and stress over the past week. The Depression Anxiety Stress Scales (DASS-21) is commonly used in clinical and research contexts to characterize emotional distress and support symptom monitoring.
It includes 21 items rated on a 4-point response scale and typically takes about 20 minutes to complete. Scoring yields separate subscale scores intended to reflect severity across the three symptom domains, consistent with the instrument described by Lovibond, P. F. and Lovibond, S. H. The Depression Anxiety Stress Scales (DASS-21) is not a diagnostic tool and should be interpreted alongside clinical history and other assessment data.
