Associations of Resting Heart Rate and Intelligence With General and Specific Psychopathology: A Prospective Population Study of 899,398 Swedish Men

We examined longitudinal associations of resting heart rate (RHR) and general intelligence (IQ) with two psychopathology models (correlated factors factor model). RHR IQ were measured during conscription (mean age = 18.23 years; N 899,398 Swedish males). A correlated model register-based outcomes (including 10 psychiatric diagnoses, criminal convictions, prescription anxiolytic medications; mean at follow-up 43.09 years) identified internalizing, externalizing, psychotic dimensions; the additionally a dimension. All inversely associated IQ; however, showed that several these attributable to variance rather than specific variance. In both models, weakly but significantly predicted higher internalizing lower externalizing problems. Intelligence might be transdiagnostic risk for any form psychopathology, spectra differentiated by psychobiological processes related sensitivity punishment.
