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.
The purpose of developing this questionnaire was to attempt assessing change better than the two difference versions of a single-item NPRS.
Intended Population[edit | edit source]
Those over the age of 16 with non-chronic musculoskeletal pain. 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.[1]
