The assessment of verbal aggression in adolescent and young adult dating relationships has largely relied on self-report methodology. We investigated whether information on verbal aggression derived from an observational assessment would enhance the prediction of romantic relationship satisfaction and dissolution in a sample of young adult dating relationships (N = 113). Observationally assessed verbal aggression was moderately associated with self-reported verbal aggression. Consistent with previous findings, neither self-reported nor observationally assessed verbal aggression was associated with relationship dissolution. Observationally assessed verbal aggression and self-reported verbal aggression each uniquely accounted for a substantial amount of variability in romantic relationship satisfaction. The findings of this study provide additional support for conducting multimethod assessments of verbal aggression and incorporating observational methodology in the study of aggression in young adult dating relationships.
