The Differential Role of Narcissism in the Relations Between Childhood Sexual Abuse, Dissociation, and Self-Harm.

Childhood sexual abuse (CSA) is considered a risk factor for self-harm behaviors. According to the anti-dissociation model of self-harm, the relation between CSA and self-harm is mediated by dissociation. However, inconclusive evidence supporting this model suggests that this association may be moderated by vulnerability factors. Grandiose and vulnerable narcissism represent distinct patterns of behaviors intended to deal with unmet needs of recognition. The aim of the study was to examine a model in which the relation between CSA and self-harm is mediated by dissociation, and the relation between dissociation and self-harm is moderated by grandiose narcissism and vulnerable narcissism. A battery of self-reported questionnaires including the Childhood Trauma Questionnaire, Dissociative Experiences Scale, Deliberate Self-Harm Inventory, and Brief-Pathological Narcissism Inventory were filled out by 766 college/university students. Results indicated that self-harm was related to CSA through the mediation of dissociation.
