Understanding the PHQ-4 (Patient Health Questionnaire-4)
The PHQ-4 is a validated screening tool designed to assess symptoms of anxiety and depression over the past two weeks. This self-report questionnaire consists of four questions, evaluating the patient's feelings regarding nervousness, worry, a lack of interest or pleasure in activities, and feelings of hopelessness. Each response is scored, allowing healthcare providers to gain a quick and efficient understanding of a patient's mental health status. This tool is beneficial for primary care settings, mental health professionals, and other healthcare providers who want to screen for these common mental health conditions.
