Following the publication of the article titled “A Longitudinal Examination of the Hopelessness Theory of Depression in People Who Have Multiple Sclerosis” [1], the authors identified an error in the Center for Epidemiologic Studies Depression Scale (CESD) administered to participants. In item 10: “I felt fearful” was printed as “I felt tearful.” The authors and handling editor are in agreement that the impact on the results and conclusions is negligible; however, this corrigendum serves to inform readers of this error.
