PHQ-9 Depression Screening Scale

Welcome to the "PHQ-9 Depression Screening Scale" test. This is an important step in gaining a deeper understanding of your psychological state. PHQ-9 (Patient Health Questionnaire-9) is a widely used depression symptom assessment tool in clinical and research fields. It consists of 9 questions covering nine common depressive symptoms, including depressed mood, loss of interest or pleasure, sleep problems, fatigue, appetite changes, decreased self-evaluation, attention problems, and suicidal or death thoughts.

Test Purpose and Significance

PHQ-9 uses a self-assessment method, where patients select the answer that best fits their situation based on their condition over the past two weeks. Through PHQ-9 assessment, doctors can better understand the patient's current depressive symptom status and severity, which will help doctors make more accurate diagnoses and develop corresponding treatment plans. In addition, PHQ-9 can also be used to track treatment effectiveness, helping doctors evaluate treatment progress and changes in patient condition.

Test Content and Structure

PHQ-9 Scoring Criteria: Each question has a score, with a total score ranging from 0 to 27 points. Higher scores indicate more severe depressive symptoms. This test is a hospital-grade specialized tool that can help you quickly understand whether you may have depression in just 2 minutes.
