Conduct problems are associated with accelerated thinning of emotion-related cortical regions in a community-based sample of adolescents

•We characterize the association between age-related cerebral cortical change and conduct problems in a large longitudinal, community-based sample of adolescents (N = 1039).•Higher levels of conduct problems were associated with accelerated age-related cerebral cortical thinning.•Findings were not meaningfully altered when controlling for alcohol use, co-occurring psychopathology, and socioeconomic status.•This work represents the largest study to date of conduct problems and cerebral cortical thickness development.
