Background/Objective: The main purpose of this study was to examine the rela-tionships among cybervictimization, maladaptive cognitive emotion regulation strategies andsomatic complaints in a 4-month follow-up study. Method: A total of 1,024 high school students(456 male and 568 female, M (SD) = 13.69 years (1.3 years), range 12---18 years, voluntarily par-ticipated in this study. Measures of cybervictimization and cognitive strategies were obtainedat Time 1. Four months later (Time 2), measures of somatic complaints were obtained. Results:Multiple mediation analyses were conducted to determine the mediating roles of maladaptivestrategies in the link between cybervictimization and somatic complaints. As expected, path-analytic results showed that cybervictimization predicted somatic symptoms. Furthermore,some maladaptive regulation strategies, namely self-blame and rumination, partially medi-ated the link between cybervictimization and somatic symptoms evaluated 4-months later.Conclusions: The findings are discussed in terms of the role that maladaptive cognitive emotionregulation strategies might play with regards to physical health in cyberbullying episodes. Ingeneral, these findings have important implications for developing an understanding about theaffective determinants of somatic health problem initiation and maintenance after a victim-ization and for developing intervention programs specifically for cybervictimized adolescents.© 2020 Published by Elsevier Espa˜na, S.L.U. on behalf of Asociaci´on Espa˜nola de Psicolog´ıa Con-ductual.
