A Study Space Analysis and Narrative Review of Trauma-Informed Mediators of Dating Violence.

Research linking child maltreatment and dating violence in adolescence and emerging adulthood has proliferated in the past two decades; however, the precise mechanisms by which these experiences are related remain elusive. A trauma-informed perspective suggests four particularly promising mediators: maladaptive attachment, emotion regulation difficulties, emotional distress, and hostility. The current article characterizes the status of the empirical literature examining these four mediators using a study space analysis and a narrative review of existing research. An extensive literature search identified 42 papers (44 studies) that met the following criteria: (1) at least one measure of child maltreatment (emotional, physical, sexual, neglect, or exposure to intimate partner violence); (2) a measure of one of the four mediator variables; (3) a measure of dating violence perpetration or victimization; and (4) a sample of adolescents or young adults. The study space analysis suggested several important observations about the research on this topic, including a dearth of studies examining hostility as a mediator and little research using prospective designs or clinical samples. There are also limitations with the conceptualization and measurement of dating violence, child maltreatment, and some of the mediator variables. In addition, few studies examined more than one mediator variable in the same study. The narrative review suggested that maladaptive attachment (specifically insecure attachment styles), emotion regulation difficulties (specifically regulation of the emotion of anger), and emotional distress construed broadly represent promising mediators of the association between child maltreatment and dating violence, but conclusions about mediation must remain tentative given the state of the literature. The discussion offers recommendations for improved theoretical and empirical rigor to advance future research on mechanisms linking child maltreatment and dating violence.
