How do you interpret a PHQ-9 score?
Can you explain to me how to interpret a PHQ-9 score? I understand it's a tool used to assess depression symptoms, but I'm not sure how to read the results. Are there specific thresholds or ranges that indicate different levels of depression severity? Additionally, how do professionals typically use this score to inform their diagnosis and treatment plans? I'm particularly interested in how it factors into the overall assessment process.
