The P4 consists of 4 items that address pain intensity in the morning, afternoon, evening, and with activity over the past 2 days. Each item is scored on a 0-to-10 NPRS, therefore the total P4 scores can vary from 0 (no pain) to 40 (the highest possible pain level).

Summary[edit | edit source]
The P4 consists of 4 items that address pain intensity in the morning, afternoon, evening, and with activity over the past 2 days. Each item is scored on a 0-to-10 NPRS, therefore the total P4 scores can vary from 0 (no pain) to 40 (the highest possible pain level). Most patients can complete the P4 in less than a minute and clinicians can score the measure in 5 seconds without the use of computational aids.[1]
The purpose of developing this questionnaire was to attempt assessing change better than the two different versions of a single-item NPRS.[1]
Intended Population[edit | edit source]
Those over the age of 16 with non-chronic musculoskeletal pain.[1] It has also been shown to be valid when used in conjunction with the WOMAC in people with osteoarthritis awaiting total knee or total hip replacements.[2]
Method of Use[edit | edit source]
Patients are asked to circle a single number that corresponds to their pain at each time of day and with activity over the previous 2 days. The numbers are then totaled to yield a score out of 40.
Evidence[edit | edit source]
Reliability[edit | edit source]
Test-retest reliability = 0.78[1]
Validity[edit | edit source]
Longitudinal validity = 0.63 and 0.57 between the retrospective rating of change and the P4 and 24-hour NPRS (z = 1.73, P1 = .043), and 0.61 and 0.56 between the retrospective rating of change and the P4 and 2-day NPRS (z = 2.53, P1 = .006), respectively.[1]
Responsiveness[edit | edit source]
MDC90 = 9.1 points or 22.2% of the scale range[1]
