Transdiagnostic mechanisms involved in nonsuicidal self-injury,risky drinking and disordered eating: Impulsivity,emotion regulation and alexithymia

Abstract

Objective: The aim of the present study was to explore common and differential relationships between nonsuicidal self-injury (NSSI), risky drinking, and disordered eating attitudes and impulsivity, emotion dysregulation, and alexithymia. Methods: We investigated these associations in a sample of 951 college students (79.4% female, Mage = 21.86?years) by means of self-report questionnaires assessing the constructs of interest. Results: Overall, 28% of the students reported a history of NSSI, one third engaged in risky drinking, and less than 5% reported disordered eating symptoms. Negative urgency and difficulties in emotion regulation were both related to each of the three behaviors and can be considered as common transdiagnostic mechanisms. Conclusions: We discuss the implications of transdiagnostic mechanisms involved in these three dysregulated behaviors with respect to their assessment and treatment in college counseling settings.
