The Patient Health Questionnaire (PHQ-9) is an essential clinical instrument for screening, diagnosing, and monitoring the severity of depression. Used by healthcare professionals worldwide, it helps provide a clear, quantified baseline for emotional wellness based on nine critical areas of mental health.
