Brief Pain Inventory (BPI)

The BPI (Brief Pain Inventory) is a validated 9-item measure of pain severity (worst, least, average, current) and pain interference with functioning (mood, walking, work, relationships, sleep, enjoyment). Score 0–10 per item. Cleeland & Ryan (1994).

What is the Brief Pain Inventory?

The BPI (Brief Pain Inventory) is a validated self-report scale developed by Cleeland and Ryan (1994) at the MD Anderson Cancer Center to assess the severity of pain and its impact on daily functioning. It was originally developed for cancer pain research but has since been validated across a wide range of conditions including chronic musculoskeletal pain, neuropathic pain, surgical pain, and HIV-related pain. The BPI-SF (Short Form) contains 9 items and takes approximately 5 minutes to complete.

The BPI has two key composite subscales:

• Pain Severity composite, the mean of 4 items rating worst pain, least pain, average pain, and pain right now, each on a 0–10 NRS. This gives an overall severity score 0–10.
• Pain Interference composite, the mean of 7 items rating pain interference with general activity, mood, walking, normal work, relationships, sleep, and enjoyment of life, each 0–10. Provides an overall functional impact score 0–10.

Scores of ≥4 on either subscale are commonly used to define clinically significant pain in clinical trials and practice guidelines (World Health Organization Analgesic Ladder context). The BPI is free for non-commercial clinical and research use; copyright is held by Charles S. Cleeland, PhD; the scale is administered through the Department of Symptom Research at MD Anderson Cancer Center.
