In the article by McBeth et al titled “Cognitive Behavior Therapy, Exercise, or Both for Treating Chronic Widespread Pain,” published in the January 9, 2012, issue of Archives of Internal Medicine (2012;172:48-57. doi:10.1001/archinternmed.2011.555), coding errors occurred in 3 of the secondary outcome scales: the Chronic Pain Grade questionnaire, the Fatigue scale, and the Sleep scale. The corrected data are presented below in Tables 1, 2 and 3 that match the published tables. Because the analysis of the primary outcome data was adjusted for Chronic Pain Grade scores, this analysis has been repeated and is presented below in Table 3. Amendment of these coding errors does not significantly change the reported results or change the study conclusions.
