The aim of the current research was to disentangle four theoretically sound models of externalizing behavior etiology, i.e. attachment, language, inhibition and parenting, by testing their relation with behavioral trajectories from early childhood to adolescence. The aim was achieved through a 10-year prospective longitudinal study conducted over 5 waves with 111 referred children aged 3 to 5 years at the onset of the study. Clinical referral was primarily based on externalizing behavior. A multi-method (questionnaires, testing and observations) approach was used to estimate the four predictors in early childhood. In line with previous studies, the results show a significant decrease of externalizing behavior from early childhood to adolescence. The decline was negatively related to mothers’ coercive parenting and positively related to attachment security in early childhood, but not related to inhibition and language. The study has implications for research into EB etiology recommending to gather hypotheses from various theoretically sound models to put them into competition with one another. The study has also implications for clinical practice by providing clear indications for prevention and early intervention.
