3 min read 11-03-2025

The PHQ-9, or Patient Health Questionnaire-9, is a widely used self-report questionnaire designed to assess the severity of depressive symptoms. Understanding how to score and interpret your PHQ-9 results is crucial for managing your mental health. This article will guide you through the process, explaining each step and offering context for your score. Remember, this information is for educational purposes only and does not substitute professional medical advice. Always consult a healthcare professional for diagnosis and treatment.

Understanding the PHQ-9 Questionnaire

The PHQ-9 consists of nine questions, each assessing a different symptom of depression over the past two weeks. Each question uses a four-point scale, ranging from "not at all" (0 points) to "nearly every day" (3 points). The total score ranges from 0 to 27.

How to Score Your PHQ-9

Review each question: Carefully read each of the nine questions on the PHQ-9 questionnaire.
Rate your symptoms: For each question, select the answer that best reflects how often you have experienced that symptom over the past two weeks.
Assign points: Assign the corresponding point value (0-3) to each answer.
Calculate your total score: Add up the points from all nine questions. This is your total PHQ-9 score.

Interpreting Your PHQ-9 Score

Your PHQ-9 score provides an indication of the severity of your depressive symptoms. Here's a general interpretation guideline:

0-4: Minimal or no symptoms.
5-9: Mild depression.
10-14: Moderate depression.
15-19: Moderately severe depression.
20-27: Severe depression.

Important Note: These are guidelines only. Your score should be considered in the context of your overall health and well-being. Other factors, such as your medical history and current life circumstances, should also be taken into account.

What Your Score Means

Minimal or no symptoms (0-4): While a low score is encouraging, it's still important to maintain healthy habits and address any underlying concerns.
Mild to Moderate Depression (5-14): If you score in this range, you may benefit from lifestyle changes, such as increased physical activity, improved sleep hygiene, and stress management techniques. Therapy might also be beneficial.
Moderately Severe to Severe Depression (15-27): A score in this range strongly suggests the presence of depression requiring professional help. It's essential to seek treatment from a healthcare professional, such as a psychiatrist or therapist, who can provide a proper diagnosis and develop a treatment plan that may include medication and therapy.

Frequently Asked Questions About PHQ-9 Scoring

What if my score is higher than expected?

A higher-than-expected score indicates a greater need for professional help. Don't hesitate to seek medical attention. A healthcare professional can provide a diagnosis and recommend appropriate treatment options.

Can the PHQ-9 diagnose depression?

No, the PHQ-9 is a screening tool, not a diagnostic test. While it provides a strong indication of the severity of depressive symptoms, a formal diagnosis requires a comprehensive evaluation by a mental health professional.

How often should I take the PHQ-9?

The frequency of taking the PHQ-9 depends on your individual needs and your healthcare provider's recommendations. It might be used as a baseline measurement, and then repeated at intervals to monitor the effectiveness of treatment.

Are there other similar questionnaires?

Yes, several other questionnaires assess depression symptoms, including the Beck Depression Inventory (BDI-II) and the Center for Epidemiologic Studies Depression Scale (CES-D).
