Depression affects how you feel, think, and handle daily life β from sleep and appetite to energy and self-worth. Our depression screening section brings together clinically validated tools including the PHQ-9, CES-D, SDS, and BHS. Widely used in both clinical and research settings, these instruments help identify depressive symptoms and track changes over time. Each assessment is anonymous, takes 3-10 minutes, and delivers instant results with clear interpretation. These screenings are educational tools β if you're experiencing thoughts of self-harm, please contact a crisis helpline immediately.
