There have been studies establishing the relationship between moral disengagement and aggressiveness in various contexts, especially in the role of the aggressor. Few, however, have analyzed moral disengagement’s mediating role in the phenomenon of teenage dating violence, taking into account how these mechanisms affect the victims’ perception of themselves as fearful, trapped, or mistreated in a dating relationship. This study analyzes the relationship between moral disengagement, the acceptance of violence, and how the victims of this type of abuse perceive victimization. The participants were 2577 adolescents between the ages of 14 and 18. They completed two questionnaires that addressed teenage dating violence and moral disengagement. To study the relationship between the variables, factorial, structural, correlation, and hierarchical multiple regression analyses were performed to construct the perceptual structure of victimization. The analyses showed moral disengagement and the acceptance of violence, as well as their interaction, to have a mediating and moderating influence by modifying the perception of victimization. The victims’ levels of moral disengagement explained their acceptance of the violence and their inability to recognize abuse. Finally, these results may be a key element in the design of psychological interventions aimed at minimizing the use of moral disengagement and the acceptance of violence in situations involving aggression in teenage dating.
