The longitudinal relationship between borderline personality features, disordered eating behaviour, and the role of impulsivity were examined using a sample of 643 Canadian adolescents from the McMaster Teen Study. Participants were assessed annually, beginning in Grade 7 until Grade 12.Using path analysis, the results suggest that higher symptoms of impulsivity increase an adolescent’s risk of engaging in disordered eating behaviour, as well as developing borderline personality features in later years. Results also showed a bidirectional relationship between these variables, whereby borderline personality features and disordered eating influence one another throughout time. As well, disordered eating appeared as an antecedent for borderline personality features. The findings highlight the importance for clinicians to be aware of the high comorbidity of disordered eating, borderline personality features, and impulsivity, and that early interventions that target impulsivity and problematic eating behaviour may mitigate the risk of future borderline personality features. Clinical implications, limitations, and future directions are discussed.
