PEG Pain Scale: Pain, Enjoyment and General Activity

The PEG asks three questions about the past week: average pain, and how much pain has got in the way of enjoying life and of general activity. Each is rated 0 to 10, and the mean of the three, from 0 to 10, tracks chronic pain treatment over time. See how to score it, what a score and a change in score mean, and record the result with the free template. The official wording is in the 2009 paper.

Who holds it

Erin E. Krebs, Kurt Kroenke and colleagues, who published it in the Journal of General Internal Medicine in 2009. Its three items are adapted from the Brief Pain Inventory, copyright Dr. Charles S. Cleeland.

How you may use it

The PEG was published in an open-access paper, with the Brief Pain Inventory items used by permission of Dr. Cleeland. Public health agency guides reproduce it free of charge, describe it as public domain, and ask users to cite the 2009 paper. This page describes it and links to the paper for the official wording.

Use it for

  • Chronic pain reviews
  • Long-term opioid therapy
  • Primary care follow-up
  • Pain self-management programs
  • Measurement-based care

What the score means. 0 to 10, mean of three 0 to 10 ratings, higher means worse.

0 to 3.9: None to mild

Little pain, and little interference with enjoyment or activity. For many people with chronic pain this is a good result: keep what is working, and keep tracking.

4 to 6.9: Moderate

Pain gets in the way of enjoyment and activity on many days. Check the score against the baseline and the patient’s function goals, and review the plan.

7 to 10: Severe

Pain dominates daily life. Look for a reason it is worse, check mood and sleep, and ask whether the current treatment is helping at all.
  • The PEG takes three items from the Brief Pain Inventory: average pain over the past week, how much pain has interfered with enjoyment of life, and how much it has interfered with general activity. Each is rated from 0 to 10.
  • The score is the mean: add the three ratings and divide by 3, for a score from 0 to 10. Higher means worse pain and more interference. Record each rating as well as the mean, since the items can move apart.
  • The developers set no cutoffs or severity levels. The levels on this page follow the usual split for 0 to 10 pain ratings, to put a number into words: under 4 none to mild, 4 to 6.9 moderate, 7 and above severe. They aren’t decision cutoffs.
  • Some clinic forms round the mean to the nearest whole number. Rounding can move a score across a level, 3.7 to 4 for example, so use the same method at every visit. This page keeps one decimal place.
  • All three items are needed. Ask any blank item before the patient leaves; the mean of two items isn’t a PEG score.
  • A fall of 30% or more from baseline is the usual mark for meaningful improvement. The CDC’s 2022 opioid guideline suggests the PEG and defines clinically meaningful improvement as 30% in both pain and function.
  • In points, a 2024 analysis of six trials put the smallest meaningful change at about 1 point, with 2 points as an upper bound. In the 2009 study, patients who said they had improved fell by about 3 points over 6 months.

How to give it, score it, and read it.

Giving it

The patient answers three questions about the past week, on paper, on a tablet or portal, or aloud. It takes under a minute.

  • Use the published wording and its 0 to 10 anchors, from the 2009 paper
  • Ask about the past week, not the pain at the visit
  • Take one whole-number rating for each question
  • Give it the same way at every visit, on paper, on screen, or aloud

Avoid: Asking “How is your pain today?” and recording the answer as the first item. The PEG asks about average pain over the past week.

Scoring

Add the three ratings and divide by 3, for a score from 0 to 10.

  • Record all three ratings, not only the mean
  • Keep the mean to one decimal place, or round it the same way every time
  • Ask about any blank item before the patient leaves

Avoid: Reporting the sum, from 0 to 30, as the score. A sum of 18 is a PEG of 6.0, and a chart that mixes the two makes the trend meaningless.

Reading the score

Higher means worse. There are no official cutoffs, so read it against the patient’s own baseline and goals.

  • See which item drives the score: pain, enjoyment of life, or activity
  • Ask what the numbers mean in daily life: walking, work, sleep, time with others
  • Check mood, since depression and anxiety raise the interference ratings
  • Compare with the baseline before comparing with the levels

Avoid: Treating the descriptive level as a decision. A 6.0 that was 8.7 at baseline is a success; a 6.0 that was 6.3 isn’t.

Tracking change

Take a baseline before a new treatment starts, then repeat the PEG at every review of that treatment.

  • Work out the percent change from baseline: 30% lower is the usual mark for meaningful improvement
  • Note the change in points too: about 1 point is the smallest change worth noting
  • Ask directly whether pain or function is worse: the 2009 study didn’t show that the PEG picks up worsening well
  • Keep the same format and the same rounding each time

Opioid therapy reviews

The PEG gives a number for the benefit side of the review, to weigh against side effects and risks.

  • Agree on function goals and take a PEG before starting or raising an opioid
  • Review within 1 to 4 weeks of starting or raising the dose, then about every 3 months or more often
  • Look for a 30% improvement in both pain and function, the average pain item and the two interference items
  • When there is no meaningful improvement, talk through tapering, other treatments, or both

Avoid: Judging benefit on the pain rating alone. If pain is lower but enjoyment and activity haven’t moved, the treatment hasn’t met its goal.

PEG result: knee osteoarthritis on a long-acting opioid, 3-month review

Family practice, scheduled review 3 months after starting a buprenorphine patch

PEG score

61-year-old man with osteoarthritis of both knees, worse on the right, for 6 years. Asked aloud at the visit. Average pain 7, enjoyment of life 7, general activity 7. Sum 21 ÷ 3 = 7.0, severe.

Compared with baseline

Baseline 8.0 on August 4, the day the patch started: pain 8, enjoyment 7, activity 9. At the 4-week check, 6.3. Now 7.0: down 1.0 point, 12.5% from baseline, well short of the 30% mark. The early gain at 4 weeks didn’t last.

Function goals

Goals set in August: walk the dog around the block, about 20 minutes, and stand at his workbench for an hour. Now he walks 10 minutes with two stops, and manages 20 minutes at the bench. Neither met. In his words: “It takes the edge off, but I’m not doing any more than before.”

Treatment and plan

Buprenorphine patch 10 micrograms an hour, changed weekly, with acetaminophen 1 g three times a day and diclofenac gel. Oral anti-inflammatories stopped in the spring for kidney function, eGFR 48. Safety review: constipation, eased with senna; no drowsiness; prescription monitoring check matches; naloxone at home. Decision: no meaningful benefit in pain or function at 3 months, so we agreed to stop the patch: 5 micrograms an hour for 2 weeks, then off. Physical therapy for a knee strengthening program, and referral to orthopedics to discuss a right knee replacement. Next PEG at the 2-week taper check, then in 3 months.

Common mistakes, and how to avoid them.

Reporting the sum as the score

Ratings of 6, 7 and 5 add up to 18, but the PEG is 6.0. Record the mean, so every visit is on the same 0 to 10 scale.

Asking about today’s pain

The first item asks about average pain over the past week. A rating of the pain in the exam room is a different number, and often a higher one.

Judging benefit on pain alone

Enjoyment of life and general activity are the function half of the PEG. A lower pain rating with no change in either isn’t a meaningful benefit.

Starting treatment with no baseline

Without a PEG before a new opioid, injection, or program, the 3-month review has nothing to compare with. Take it at the first visit.

Reading the levels as cutoffs

The PEG has no official bands. A move from 8.7 to 6.0 is a 31% fall and a good result, even though both scores sit above 4.

Frequently asked questions.

How do you score the PEG pain scale?

Rate each of the three items from 0 to 10: average pain over the past week, interference with enjoyment of life, and interference with general activity. Add the three and divide by 3. Ratings of 6, 7 and 5 give 18 ÷ 3 = 6.0. Some forms round to the nearest whole number; whichever you use, use it every time.

What does a PEG score mean?

Higher means worse pain and more interference with daily life. The developers set no cutoffs. This page uses a common descriptive split for 0 to 10 pain ratings: 0 to 3.9 none to mild, 4 to 6.9 moderate, and 7 to 10 severe. The patient’s own baseline matters more than the level.

What change in PEG score is meaningful?

A fall of 30% or more from baseline is the usual mark. The CDC’s 2022 opioid guideline defines clinically meaningful improvement as 30% in both pain and function, and chronic pain research uses 30% for a moderate, meaningful improvement. In points, a 2024 analysis of six trials put the smallest meaningful change at about 1 point, with 2 as an upper bound.

How is the PEG different from the Brief Pain Inventory?

The PEG takes three items from the Brief Pain Inventory: average pain and two of its interference items, enjoyment of life and general activity. The full inventory asks about pain at several points, interference in more areas of life, where the pain is, and relief from treatment. The PEG takes under a minute; in the 2009 study it tracked the inventory’s interference scale closely, with correlations of 0.89 and 0.95 in two groups of patients. Use the inventory for detail and the PEG for quick, repeated tracking.

How is the PEG used in opioid therapy reviews?

Take a PEG and agree on function goals before starting an opioid. Repeat it within 1 to 4 weeks of starting or raising the dose, then about every 3 months or more often. If pain and function haven’t improved by about 30%, or harms outweigh the benefit, talk through tapering, other treatments, or both.

Who can give the PEG?

Anyone on the team. The patient answers on paper, on a tablet or portal, or aloud to a nurse, medical assistant, therapist, or clinician, and a clinician reads the result with them. It was developed in adults with chronic back, hip, or knee pain in primary care, and checked in a second group of veterans with chronic pain.

Is the PEG free to use?

Yes. It was published in an open-access paper in 2009, and public health agency guides reproduce it free of charge and describe it as public domain, asking users to cite the paper. Its items are adapted from the Brief Pain Inventory with Dr. Charles Cleeland’s permission. Get the official wording from the 2009 paper.
