Body maps have long been used to assess pain location in adult and pediatric chronic pain patients. Assessing agreement between parent and child reports of pain location using such maps may help establish a unified picture of children's pain experience. However, few studies have examined the extent of agreement between mothers and children on the location of the child's pain. Using kappa coefficients and other determinants of the magnitude of kappa we assessed mother-child concordance in pain location using body maps with 21 standardized areas in 41 children with chronic pain (65.9% female, mean age = 14.60) and their mothers. The highest level of agreement was found for the abdominal region; agreement for the head region was moderate and not superior to the other body areas. Approximately half of the body map areas yielded poor to fair mother-child agreement, while the other half yielded moderate or better agreement. There was more agreement between mothers and sons than between mothers and daughters on the total number of body areas considered painful, but there were no effects of pubertal status, race, and ethnicity on agreement. Our results are consistent with previous studies indicating that parent assessments of children's pain do not necessarily mimic their child's report. Future research should test additional psychosocial factors that may contribute to parent-child discordance regarding the location of the child's pain.
