PEG Scale Assessing Pain Intensity and Interference (Pain, Enjoyment, General Activity)

Description of Instrument

The PEG is a brief, convenient, patient-reported pain outcome measure that is derived from the Brief Pain Inventory. The PEG includes 3 items assessing pain intensity and functional interference (i.e., interference with enjoyment of life and general activity); it has demonstrated good reliability, validity, and responsiveness in large samples of chronic pain patients in primary care, VA hospitals, and pain management centers (Krebs, et al., 2009; Kabore et al., 2020). The PEG is scored by averaging the items; scores range from 0-10. Its excellent psychometric properties and responsiveness to treatment compare favorably to other established measures such as the PROMIS and SF-36 pain scales (Kean et al., 2016).
