Rating Scales and Measurement-Based Care: What Those Questionnaires Are For
Short answer
Rating scales are short, standardized questionnaires, such as the PHQ-9 for depression or the GAD-7 for anxiety, that turn symptoms into a score. Measurement-based care means filling them out again over time and talking through the results, so you and your clinician can see whether treatment is helping. A score is a snapshot that supports a clinician's judgment. It does not make a diagnosis on its own.
In crisis or thinking about suicide? Call or text 988 now (in New York City it reaches NYC 988). If you are in immediate danger, call 911.
This guide is not enough if
- A questionnaire answer reflects thoughts of suicide or self-harm right now: call or text 988, or call 911.
- You want to score yourself and decide on a diagnosis or a medicine change alone.
- You need formal psychological testing of attention, memory or learning.
- Your score has changed and you want to adjust a medicine: talk with your prescriber first.
Why your clinician keeps handing you a questionnaire
You check in for a visit and there it is again: a short form asking how often you have felt down, worried or unable to focus lately. It can feel like paperwork. In practices that use it well, it is part of how care is tracked. The American Psychiatric Association notes that the field has been slow to adopt it routinely, so not every clinician works this way.
These forms are called rating scales or symptom measures. The American Psychiatric Association lists several that were developed to be given at the first interview and to monitor treatment progress (opens in a new tab) afterward. NIMH also lists measures of progress, such as rating scales tracked over time, among the parts of effective therapy for children.
This guide explains what the common scales are and what they can show. For how therapy goals are set more broadly, see how therapy goals are set and measured.
What measurement-based care means
A 2023 American Psychiatric Association resource document defines measurement-based care as repeatedly assessing psychiatric symptoms (opens in a new tab) through structured means to inform care. In February 2025, the American Psychological Association approved practice guidelines on measurement-based care (opens in a new tab) that describe three steps: collect data by giving measures repeatedly during treatment, share and discuss the results with the patient, and act by using them in decisions about the treatment plan and goals.
The key word is repeated. The American Psychological Association guidelines say that simply giving measures is not the same as high-quality measurement-based care. A 2017 research review published in Psychiatric Services described one-time screening, measuring symptoms infrequently and feeding results back to clinicians outside the visit as ineffective approaches. The value comes from looking at the trend together and deciding what to do next.
The questionnaires you are most likely to see
These are common examples. Your clinician may use others that fit your situation:
- PHQ-9 (depression). Nine questions, one for each depression criterion, each scored from 0 (not at all) to 3 (nearly every day). In the study that validated it, published in 2001 and indexed by the National Library of Medicine, the PHQ-9 was a reliable and valid measure of how severe depression is. The American Psychiatric Association offers an adapted version as its adult depression severity measure, with total scores from 0 to 27, plus a version for ages 11 to 17.
- GAD-7 (anxiety). Seven questions. Its 2006 validation study describes it as a valid and efficient tool for screening for generalized anxiety disorder and assessing its severity.
- ADHD rating scales and checklists. NIMH says providers use standardized behavior rating scales or ADHD symptom checklists as part of an evaluation, along with history. With permission, they may also talk with people who see you or your child in different settings.
- Broad symptom checklists. The American Psychiatric Association's Level 1 cross-cutting measures are brief surveys of 13 symptom areas for adults and 12 for children and teens, with a version for parents of children age 6 to 17. They point to areas worth asking more about.
| Measure | What it asks about | Who fills it out | What it is not |
|---|---|---|---|
| PHQ-9 | Nine depression symptoms, including thoughts of self-harm | You (self-report) | A diagnosis on its own |
| GAD-7 | Seven anxiety symptoms | You (self-report) | A diagnosis on its own |
| ADHD rating scales and checklists | Attention, hyperactivity and impulsivity symptoms | Varies by scale; your clinician will say who completes it | A substitute for history and input from several settings |
| DSM-5-TR Level 1 cross-cutting measure | A brief screen across many symptom areas | You, or a parent for children age 6 to 17 | A full assessment; it points to areas to explore |
What a score can and cannot tell you
A score can show how strong symptoms are right now and, over several visits, whether they are going up or down. In the PHQ-9 study, scores of 5, 10, 15 and 20 represented mild, moderate, moderately severe and severe depression. Seeing a number fall, or not fall, can make a conversation about treatment more concrete.
A score cannot diagnose you by itself. The American Psychiatric Association says its measures should be used to enhance clinical decision-making and not as the sole basis for a diagnosis. Scores also do not explain why symptoms changed. A bad week, poor sleep, a new stress or a medical issue can all move a number, which is why your clinician asks about context. How diagnosis is actually reached is covered in how psychiatric diagnosis works.
Answering honestly and tracking between visits
Some forms ask about thoughts of death or self-harm; the PHQ-9, for example, asks about thoughts that you would be better off dead or of hurting yourself. If you are having those thoughts and feel unsafe now, call or text 988, or call 911, rather than waiting for your next visit. If the thoughts come and go, write them on the form and say them out loud too, so your clinician can talk with you about them.
For everything else, a few habits make the results more useful:
- Answer for the time period the form names, not just today. The American Psychiatric Association's version of the PHQ-9, for example, asks about the last 7 days.
- Do not aim for a good or bad score. The goal is an accurate picture, not a grade.
- Note what else changed, such as a new medicine, a missed dose, illness, travel or a hard week.
- Ask to see your scores over time. The American Psychological Association guidelines describe sharing and discussing results with patients.
- Keep simple notes between visits. For ADHD, monitoring ADHD treatment has practical tracking ideas.
- Bring questions about the trend to your next appointment instead of changing treatment on your own.
When a questionnaire is not the right tool
Rating scales track symptoms. They are not designed to measure skills such as memory, attention or learning in the depth that formal testing does; for that, see psychological testing vs. psychiatric evaluation.
If your scores have not improved after a fair trial of treatment, raise it with your clinician. That conversation may lead to a change in the plan, more evaluation or a second opinion; second opinion or stay with your prescriber can help you think it through. If you take medicine, do not stop or change it based on a score; talk with your prescriber. The practice's medication management and evidence-based therapies pages describe how care is followed over time.
Frequently asked questions
What does my PHQ-9 score mean?
The PHQ-9 adds up nine answers scored 0 to 3. In the original 2001 study, scores of 5, 10, 15 and 20 represented mild, moderate, moderately severe and severe depression. Your score is one piece of information. Your clinician reads it alongside your history and how you are doing, and the trend across visits often says more than one number.
Is a high GAD-7 score a diagnosis of anxiety?
No. The GAD-7 was developed as a brief tool for screening for generalized anxiety disorder and assessing its severity. A high score suggests that anxiety symptoms are worth a closer look, and a clinician then considers your history and other possible causes. The American Psychiatric Association says measures like these should not be the sole basis for a diagnosis.
How often should rating scales be repeated?
It depends on your treatment and your clinician. The idea behind measurement-based care is repeated measurement during treatment, and a 2017 research review described one-time screening and infrequent measurement as ineffective. Some clinicians ask at every visit, others at set points. You can ask how often your clinician plans to check and how they will use the results.
What should I do if my score gets worse?
Tell your clinician, and do not change or stop a medicine on your own. A worse score can reflect a hard week, a new stress, a physical illness or a sign that the plan needs another look. If the change includes thoughts of suicide or self-harm and you feel unsafe, call or text 988, or call 911.
