Summary

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).

The purpose of developing this questionnaire was to attempt assessing change better than the two difference versions of a single-item NPRS.
