Nine-item self-rating depressive symptoms scale (Patient Health Questionnaire-9, referred to as PHQ-9).
The PHQ-9 is a simple, effective depressive symptom assessment tool that is widely used in clinical and research fields. It consists of nine questions covering nine common depressive symptoms, including low mood, loss of interest or happiness, sleep problems, feelings of fatigue, changes in appetite, decreased self-esteem, concentration problems, thoughts of suicide or death, etc.
PHQ-9 adopts a self-assessment method, that is, patients choose the answer that best suits their situation based on their situation in the past two weeks. PHQ-9 scoring standard: The answer to each question has a score, and the total score ranges from 0 to 27. The higher the score, the more severe the depressive symptoms are.
Through the assessment of PHQ-9, doctors can better understand the patient’s current depressive symptom status and its severity. This will help doctors make more precise diagnoses and develop appropriate treatment plans. In addition, PHQ-9 can also be used to track treatment effects and help doctors evaluate the progress of treatment and changes in patients’ conditions.
It should be emphasized that the PHQ-9 is only an assessment tool and cannot be used as the only basis for diagnosing depression. If you are concerned that you may be suffering from depression, I recommend consulting with a professional psychologist or medical provider for a thorough evaluation and diagnosis.
In summary, the PHQ-9, as a commonly used depressive symptom assessment tool, plays an important role in the field of mental health. It can provide valuable information to help doctors understand patients’ depressive symptoms and provide a basis for developing personalized treatment plans.
