Components of the PHQ-9 Questionnaire
The PHQ-9 consists of 9 questions evaluating the frequency of depression symptoms over the past two weeks. Each item is scored from 0 to 3, with higher scores indicating greater symptom severity. The questionnaire includes questions about feelings of sadness, loss of interest, sleep disturbances, fatigue, appetite changes, feelings of worthlessness, concentration difficulties, and thoughts of death or self-harm. These components are derived from the diagnostic criteria for major depressive disorder as outlined in the DSM-5. The tool is brief, making it practical for clinical and research settings. The questions are straightforward, allowing patients to self-report their symptoms accurately. This structure ensures comprehensive assessment of depressive symptoms, aiding in diagnosis and monitoring treatment progress. The PHQ-9 is widely validated and is considered a reliable measure for detecting and assessing depression severity.
Scoring Interpretation for PHQ-9
The PHQ-9 is scored by summing the responses to its 9 items, each rated on a scale from 0 to 3 (not at all to nearly every day). The total score ranges from 0 to 27. Interpretation of scores is as follows: 0-5 indicates no or minimal depression, 6-10 suggests mild depression, 11-15 indicates moderate depression, 16-20 points to moderately severe depression, and 21-27 signifies severe depression. A cutoff score of 10 or higher is often used to identify individuals with clinically significant depressive symptoms. This scoring system aids clinicians in diagnosing depression, monitoring symptom progression, and evaluating treatment effectiveness. The PHQ-9’s scoring interpretation is straightforward, making it a valuable tool for both clinical practice and research settings.
