Table 2 PEG and Individual Item Statistics at Baseline in Study 1 and Study 2

From: Development and Initial Validation of the PEG, a Three-item Scale Assessing Pain Intensity and Interference

  Study 1 (n = 500) Study 2 (n = 638)
Mean (SD) Mean (SD)
PEG scale 6.1 (2.2) 4.1 (3.1)
Item 1: average pain intensity 6.1 (1.9) 3.9 (2.8)
Item 2: interference with general activity 6.4 (2.7) 4.4 (3.6)
Item 3: interference with enjoyment of life 5.9 (3.3) 4.0 (3.9)
  1. Study 1 included primary care patients with chronic musculoskeletal pain; Study 2 included ambulatory VA patients, 61% of whom had current pain. For each item, the response range is 0–10; the PEG scale score is the mean of the three individual item scores. Higher scores represent worse pain.
