Low resting heart rate (HR) is a known risk indicator for the development of antisocial behavior (ASB) and other clinical problems. Stimulation seeking and fearlessness have been explored as factors underlying the HR/ASB relationship, but these have often been conflated, which has complicated interpretation. We examined HR’s associations with ASB and other outcomes in terms of biobehavioral traits described by the triarchic model of psychopathy using data (N = 710) from a longitudinal study of ASB risk. Low resting HR in childhood was related to adult ASB, and covariance between ASB and traits of disinhibition and boldness largely accounted for this association. In addition, low childhood HR was related to greater externalizing problems and fewer internalizing problems in adulthood; disinhibition accounted for the former association, and boldness accounted for the latter. Findings indicate a role for both disinhibition and boldness in associations between early HR and later clinical outcomes and have implications for theory and practice.
