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

to appropriate pain management, but single-item “pain screening ” provides limited information about chronic pain. Multidimensional pain measures such as the Brief Pain Inventory (BPI) are widely used in pain specialty and research settings, but are impractical for primary care. A brief and straightforwardmultidimensional painmeasure could potentially improve initial assessment and follow-up of chronic pain in primary care. OBJECTIVES: To develop an ultra-brief pain measure derived from the BPI. DESIGN: Development of a shortened three-item pain measure and initial assessment of its reliability, validity, and responsiveness. PARTICIPANTS: We used data from 1) a longitudinal study of 500 primary care patients with chronic pai
