AbstractChronic pain is a common condition in persons with cerebral palsy (CP), although there is a paucity of research studying CP-related pain. One of the barriers to a better understanding of pain in persons with CP is the lack of information concerning the validity of pain measures that may be used with this population. The purpose of this study was to determine the relative validity of several pain measures in a sample of persons with CP-related pain. Six pain rating scales and measures of depression and pain interference were administered to a sample of 45 adults participating in a longitudinal study of pain in persons with CP. An additional 24 persons with CP were administered 5 of the 6 pain intensity scales. The results of factor analyses support the validity of each measure of pain in this sample of persons with CP. However, an examination of the pattern of associations between each of the pain ratings with measures of pain interference and depression suggest that the 7-point Faces Scale may be somewhat less valid than the other measures.2003 by the American Pain Society
