Measuring participation in patients with chronic back pain-the 5-Item Pain Disability Index

It is important that outcome measures of participation are included in back pain research to gauge the effects of painful spinal conditions and interventions on maintaining valued social roles. A simple, concise measure would be very useful for this purpose in clinical and research settings. The results of this study support the construct validity of the 5-Item PDI as a brief measure of participation in people with chronic back pain. These findings are likely most applicable to those with chronic back pain attending pain clinics and other tertiary centers for care.
