What does PHQ-9 stand for?

PHQ-9 stands for the Patient Health Questionnaire-9, a nine-item self-report scale used to track depressive symptoms over the past two weeks. Each item is scored 0 to 3, giving a total from 0 to 27. Higher numbers mean more symptoms, and the trend over time is what guides treatment.

What is a "good" PHQ-9 score?

A "good" PHQ-9 score is generally under 5, which is considered minimal or no depressive symptoms and is the threshold we use for remission. A score from 5 to 9 is mild and may still need attention, especially if it has been climbing. We focus on where your score is going, not just where it lands today.

What does GAD-7 measure?

GAD-7 measures generalized anxiety symptoms across seven questions covering worry, restlessness, irritability, and trouble relaxing over the past two weeks. Scores run from 0 to 21, with higher numbers meaning more frequent anxiety. It is one of the best validated quick checks for anxiety in primary care.

Is ASRS a diagnosis for ADHD?

ASRS is not a diagnosis for ADHD. It is a screening tool that flags adults whose attention and impulsivity patterns are worth a longer look. A high ASRS, especially on Part A, leads to a clinical interview, history review, and workup for other conditions that can mimic ADHD, like sleep apnea or anxiety.

How often should I retake these scores?

You should retake these scores every 4 to 6 weeks after any change in treatment, and at least once or twice a year as a check-in. That cadence catches improvement, plateaus, or new dips early. If something feels off between visits, you can fill them out and send them in without waiting.

Are these scores confidential?

Yes, these scores are confidential and stored in your medical chart, protected by the same privacy rules as the rest of your record. We share results only with you and the team caring for you, unless you ask us to involve someone else, like a therapist or partner. The point is to track your symptoms, not to label you.

Can I take these scores online?

Yes, you can take these scores online through your patient portal before a visit, which gives us time to review them in advance. Many people find it easier to answer honestly at home than in a busy office. We will go through the results together at your appointment.

Do high scores mean I need medication?

A high score does not automatically mean you need medication. It means your symptoms are significant enough that we should talk about options, which can include therapy, lifestyle changes, sleep work, exercise, and sometimes medication. The plan should fit your goals and preferences, not just the number on the page.

What if my score does not improve with treatment?

If your score does not improve with treatment after a fair trial of about 6 to 8 weeks, that is useful data. It tells us to change the plan, whether by adjusting a dose, switching a medication, adding therapy, or rechecking for things like thyroid issues, sleep apnea, or anemia that can blunt response. Stuck numbers are a signal, not a verdict.

Are these scores accurate for everyone?

These scores are well validated in adults across many settings, but no questionnaire is perfect. Cultural background, language, recent life events, and even how you slept last night can shift answers. That is why we treat them as one input alongside your story, exam, labs, and any wearable data.

Why is "measurement-based care" so important in mental health?

Measurement-based care is important in mental health because, without numbers, it is easy to underestimate slow improvement or miss a slow decline. Memory and mood color how we describe the past two weeks. Tracking PHQ-9 and GAD-7 scores over time gives both you and your clinician an honest, comparable record so decisions about medication, therapy, or lifestyle changes are based on real trends.

Can a wearable like an Oura ring or Apple Watch replace these scores?

A wearable cannot replace these scores, but it can complement them. Devices that track resting heart rate, heart rate variability (HRV), and sleep quality often pick up changes in stress and recovery before mood shifts. Pairing wearable data with PHQ-9 and GAD-7 trends gives a fuller picture of how mind and body are doing together.

How do thyroid and metabolic problems affect these scores?

Thyroid and metabolic problems can directly raise PHQ-9 and GAD-7 scores. Low thyroid function (hypothyroidism) can mimic depression with fatigue, low motivation, and brain fog. Insulin resistance and blood sugar swings can drive anxiety, irritability, and mood crashes. Before assuming a high score is purely psychiatric, we usually check a full thyroid panel, fasting insulin, and basic labs.

Is there a connection between sleep apnea and these scores?

Yes, there is a strong connection between sleep apnea and these scores. Untreated sleep apnea fragments sleep, raises stress hormones, and often shows up as depression, anxiety, irritability, and ADHD-like symptoms in the daytime. Treating apnea, often with a CPAP, frequently lowers PHQ-9, GAD-7, and ASRS scores at the same time as it improves energy.

Why does my PHQ-9 sometimes go up after starting therapy?

Your PHQ-9 sometimes goes up after starting therapy because real therapy asks you to face hard emotions you may have been pushing aside. In the short term, that can briefly raise distress, especially around questions about sadness or sleep. Over weeks, scores typically trend down as you build new skills and process what surfaced.

Can ADHD medication change my PHQ-9 or GAD-7 scores?

ADHD medication can change PHQ-9 or GAD-7 scores in several directions. When unrecognized ADHD is the main driver of overwhelm, treating it often lowers anxiety and depression scores at the same time. In some people, stimulant medications can raise anxiety, sleep, or appetite issues, which is why we recheck scores after starting or adjusting any treatment.

Why is it important to define remission, not just improvement?

Defining remission, not just improvement, matters because partial improvement still leaves people at higher risk of relapse and ongoing impact on work, relationships, and health. A PHQ-9 score that drops from 18 to 9 is a real win, but lingering symptoms still cost something. Aiming for under 5 sets a clearer target and tends to lead to better long-term outcomes.

How do trauma histories influence these scores?

Trauma histories influence these scores because post-traumatic symptoms often look like depression, anxiety, and attention problems all at once. PHQ-9 and GAD-7 may be elevated, and ASRS may be high because hypervigilance and intrusive thoughts mimic ADHD. When trauma is in the picture, we adjust the plan to include trauma-informed therapy, not just symptom-focused treatment.

Can hormones affect these scores?

Yes, hormones can clearly affect these scores. Perimenopause, menopause, postpartum changes, low testosterone, and thyroid shifts can all push PHQ-9, GAD-7, or ASRS numbers up. We often check hormone panels alongside these screens, especially when scores rise without an obvious life trigger.

How private are my scores?

Your scores are part of your protected medical record and are kept confidential under the same rules as any other clinical information. They are visible to your care team and to you. They are not shared with employers, schools, or insurers without your specific consent, and we use them as a clinical tool, not a label.

What if I disagree with a score I get?

If you disagree with a score, that is exactly the kind of thing we want to talk about. The score reflects how you answered on a specific day, not who you are. If a number feels too high or too low compared with how you actually feel, we explore what is driving the gap, which often reveals important context the questionnaire alone cannot capture.

What does PHQ-9 stand for?

PHQ-9 stands for the Patient Health Questionnaire-9, a nine-item self-report scale used to track depressive symptoms over the past two weeks. Each item is scored 0 to 3, giving a total from 0 to 27. Higher numbers mean more symptoms, and the trend over time is what guides treatment.

TL;DR · 30-second take

PHQ-9, GAD-7, and ASRS are short questionnaires that turn how you feel into a number we can track over time. PHQ-9 measures depression, GAD-7 measures anxiety, and ASRS screens for adult ADHD. Higher scores mean more symptoms, and falling scores mean treatment is working.

Understanding Your Scores: PHQ-9, GAD-7, and ASRS

TL;DR: Mental health is not invisible. It is measurable. We use three short, evidence-based questionnaires to track depression, anxiety, and ADHD signals over time, the same way a primary care doctor tracks blood pressure. Feeling better is great. Knowing how much better is precision medicine.

What These Scores Actually Measure

These scores are simple self-reports that ask you to rate, on a small scale, how often certain symptoms have shown up in the last two weeks. They do not replace a real conversation with a clinician. They give that conversation a clear baseline and a way to measure change. We use three:

PHQ-9 for symptoms of depression.
GAD-7 for symptoms of generalized anxiety.
ASRS for signs of adult attention deficit hyperactivity disorder (ADHD).

Each one is short, well studied, and free of charge. The point is not the score itself. The point is the trend line. If we start a new treatment, we want to see the number move in the right direction. If it does not move, we change the plan.

PHQ-9: The Depression Score

PHQ-9 stands for the Patient Health Questionnaire-9. It is a nine-question check-in for depressive symptoms over the past two weeks. Think of it as a standardized way to put words around how heavy things have felt lately. Each question is scored from 0 (not at all) to 3 (nearly every day), so the total can range from 0 to 27.

0 to 4: minimal or no symptoms.
5 to 9: mild symptoms.
10 to 14: moderate. Often the point where clinical attention helps.
15 to 19: moderately severe.
20 to 27: severe.

Our goal: not just to get you "out of the red." We aim for remission, which is a score under 5. There is also one specific question on the PHQ-9 about thoughts of self-harm, and any non-zero answer there always gets a direct conversation, not a letter or a portal message.

GAD-7: The Anxiety Score

GAD-7 stands for the Generalized Anxiety Disorder-7 scale. It is seven questions about worry, restlessness, irritability, and trouble relaxing over the past two weeks. The total runs from 0 to 21.

0 to 4: minimal anxiety.
5 to 9: mild.
10 to 14: moderate.
15 to 21: severe.

Why GAD-7 matters beyond mental health: high anxiety scores often show up disguised as physical complaints. Chest tightness that mimics heart trouble. Stomach pain or loose stools that look like irritable bowel syndrome (IBS). Insomnia that no sleep aid fully fixes. Treating the anxiety often quiets these "physical" symptoms because the nervous system finally settles down.

ASRS: The Adult ADHD Screen

ASRS stands for the Adult ADHD Self-Report Scale, developed with the World Health Organization. It is the screening tool we use for attention and focus issues in adults. It looks at two patterns:

Inattention: trouble focusing, losing track of details, finishing tasks late.
Hyperactivity and impulsivity: feeling restless, talking over people, struggling to sit still.

The screen has two parts:

Part A: the first six questions. A high score here is the strongest signal that adult ADHD is worth a deeper look.
Part B: the remaining questions. These show how much your symptoms are interfering with daily life.

Important: a high ASRS score suggests ADHD. It does not by itself diagnose it. We use the score as a starting point for a longer clinical interview that looks at history, school records, work patterns, and other conditions that can mimic ADHD, like sleep deprivation, untreated anxiety, or thyroid problems.

Why We Track Scores Over Time

We graph these scores at every visit. If we add a medication, change a dose, or start therapy, we should see the lines move within a few weeks. If they do not move, that is real information, not failure. It tells us to pivot, not push harder. That is the difference between guessing and measurement-based care. The same logic that runs your A1c trend, your blood pressure log, or your cholesterol panel applies here.

Actionable Steps in Philly

Use these scores as a tool, not a verdict.

Take the baseline: Fill out the PHQ-9 and GAD-7 at your next visit, even if you feel "fine." It gives us a starting line.
Recheck every 4 to 6 weeks: After any change in treatment, repeat the score to see if it is moving.
Pair the score with one real-life metric: Sleep hours, days you exercised, or how many times you canceled plans. Numbers plus story is the full picture.
Speak up about question 9: On the PHQ-9, the last question asks about thoughts of self-harm. If that number is anything but zero, tell us. We respond with care, not alarm.
Bring your wearable data: Resting heart rate, heart rate variability (HRV), and sleep quality often change before mood does. We look at all of it together.

Key Takeaways

PHQ-9, GAD-7, and ASRS are tools, not labels. They turn how you feel into something we can track.
Trends matter more than any single score. A score that drops from 18 to 9 is a win, even if it is not yet zero.
Remission, not "less bad," is the goal. For PHQ-9 and GAD-7, we aim for under 5.
A high ASRS is a starting point. Diagnosing adult ADHD takes a real conversation, not just a screen.
Measurement-based care reduces guessing. If a treatment is not working, the numbers tell us early.

Frequently Asked Questions

Common Questions

Deep-Dive Questions

The PHQ-9 and GAD-7 were developed by researchers, including Dr. Kurt Kroenke and Dr. Robert Spitzer, in the late 1990s and early 2000s as part of the broader Patient Health Questionnaire project. They were designed to give primary care doctors short, validated tools that map closely to the diagnostic criteria for depression and generalized anxiety. They have since been studied in millions of patients and translated into many languages.

PHQ-9 and GAD-7 relate to suicide risk through specific items, especially question 9 of the PHQ-9, which asks about thoughts of self-harm or being better off dead. Any non-zero answer there triggers a direct, supportive conversation, a safety check, and a plan that may include adjusting treatment, involving a therapist, or calling on emergency support if needed. We never treat that question as a checkbox.

Yes, these tools are used differently for older adults because depression and anxiety often show up as physical complaints, sleep changes, or memory issues rather than classic sadness. PHQ-9 and GAD-7 still work, but we read them alongside cognitive screening, fall risk, and a careful look at medications, since many drugs commonly used in older adults can mimic or worsen mood and attention problems.

We use both ASRS and a clinical interview for ADHD because the screen catches the pattern, but the interview confirms the cause. Many things look like ADHD on paper, including chronic sleep loss, untreated anxiety, depression, thyroid problems, and substance use. A careful history, school and work timeline, and sometimes input from a partner or family member helps us tell true ADHD apart from imitators.
