Objective To evaluate potential pain cutoff scores reflecting mild, moderate, and severe pain in the spinal cord injury (SCI) population and determine the relationship between the derived cutoff scores and both psychosocial and functional outcome measures. Design Retrospective analysis. Setting SCI Model Systems. Participants Persons (N=6096; age >18y) with traumatic SCI (American Spinal Injury Association Impairment Scale [AIS] grades AD; injured in 19732008). Interventions Not applicable. Main Outcome Measures Numeric rating scale (NRS) of pain severity (11 points), NRS of pain interference (5 points), Satisfaction With Life Scale, Patient Health Questionnaire-9, Craig Handicap Assessment and Reporting Technique Short-Form (CHART-SF), motor component of the FIM (M-FIM), and employment. Results The best set of pain severity cutoff points are 1 to 3, 4 to 6, and 7 to 10. This was validated by randomly assigning sample members to 2 groups and replicating. There were significant differences in all outcomes as a function of pain severity grouping, although they explained little of the variance in M-FIM and CHART-SF Physical Independence scale scores. Neurologic status differed significantly between pain groups, with incongruence between pain severity and interference in people in the AIS grade D group, who reported the greatest pain interference and least pain severity. Conclusion Pain severity can be categorized into groups that reflect pain interference. These groupings differentiate psychosocial well-being better than activity limitations. They do not provide a comprehensive pain assessment, for which pain type, location, and interference are likely to be necessary. © 2011 American Congress of Rehabilitation Medicine.
