Executive functions in perpetrators of domestic violence: a systematic review

Abstract

Executive functions correspond to a set of cognitive skills that allow for effective organization, planning, problem solving, task completion and impulse control. On the other hand, perpetrators of domestic violence are individuals who perpetrate physical, emotional, sexual or economic violence in the domestic sphere or in intimate partner relationships, referring specifically to individuals who perpetrate acts of violence against their intimate partners, spouses, ex-partners or family members in the context of the home. The aim of this article is to present and analyze the results obtained from previous studies through a quantitative systematic review, with the purpose of relating the alterations of the executive functions in the execution of violent acts in the domestic setting. A total of 497 articles were found, resulting in only 14 after a selection process based on inclusion and exclusion criteria. After a process of examination of the research variables, the results showed that alterations in executive functions such as cognitive flexibility, working memory, self-regulation and inhibitory control are associated with a higher risk of presenting acts of domestic violence. In addition, other factors were evaluated, including socioeconomic status, gender, and substance use. An examination of the results is made, establishing relationships with previous research and studies, highlighting the importance of continuing studies that expand the understanding of executive functions in domestic violence.
