Exploring the Complex Relationship Between Childhood Trauma and Self-Harm

Abstract

ABSTRACT Previous research has linked self-harm to adverse childhood experiences (i.e. abuse and neglect). Despite the extensive literature on self-harm, it remains of high importance to examine psychological predictors of repetitive self-harming behaviors in those who report childhood trauma. This study explored the role of maladaptive emotion regulation strategies, dissociation proneness, and borderline personality (BP) features. An international sample with n = 374 participants (N = 287, 77%, reporting intentional use of self-harm), was recruited online via relevant mental health platforms and research sites. Within an anonymous survey, participants completed the Self-harm Inventory, Childhood Trauma Questionnaire, Dissociative Experience Scale, Cognitive Emotion Regulation Questionnaire, and Personality Assessment Inventory-Borderline Personality Features Scale. Structural equation modeling (SEM) was used to explore direct and indirect effects. Self-harm was positively correlated to severity of childhood trauma, maladaptive emotion regulation strategies, dissociation, and BP features. In the path-analytical model, independent indirect effects of childhood trauma severity via self-blame, catastrophizing, dissociation, as well as BP features on self-harm were found. Maladaptive emotion regulation, dissociation proneness, and BP features all seem to be important intermediary agents in the close association between childhood trauma and self-harm.
