Child abuse is a traumatic experience that may have psychological consequences such as dysfunctional beliefs. The aim of this study was to analyze the impulsive behaviors (alcohol abuse, gambling, drug abuse, eating disorders, Internet abuse, videogame abuse, shopping and sex addiction) in sexual abuse survivors and to study the mediating role of early maladaptive schemas in the appearance of impulsive behaviors in adult female victims. The sample consisted of 182 adult women who had suffered childhood sexual abuse (CSA), mostly referred by associations for the treatment of childhood abuse and maltreatment. Sexual abuse was found to be positively related to the domains of Disconnection/Rejection and Impaired Autonomy. Moreover, these domains were significantly related to impulsivity and impulsive behaviors. Finally, the Disconnection/Rejection domain was found to mediate between CSA and eating disorders and alcohol abuse. These results may provide important guidance for clinical intervention.
