Forensic Psychology and Gender Violence from a Developmental Perspective: Developmental Trajectories in Victims and Aggressors

This article proposes a theoretical and empirical integration between forensic psychology and developmental theory to understand gender violence from a developmental perspective. From an interdisciplinary approach, the life trajectories of both victims and perpetrators are analyzed, taking into account individual, family, and social factors that shape their vulnerability and persistence in contexts of violence. Key explanatory models of criminal behavior—such as social learning theory, moral development, and distorted cognitive schemas—are reviewed, as well as the psychopathological consequences of chronic trauma, including complex post-traumatic stress disorder and learned helplessness. Trajectory analysis shows that childhood and adolescence represent critical stages where multiple risk factors converge: neglect, exposure to violence, dysfunctional attachment patterns, and coercive socialization. These elements are associated with an increased risk of victimization or aggression, and may become persistent if interventions are not implemented during critical developmental periods. Empirical data from longitudinal studies that corroborate the relationship between early adversity and later involvement in violent dynamics are presented, and paradigmatic cases are discussed from a forensic perspective. Finally, the implications of the developmental approach for intervention, expert assessment, and public policy formulation are highlighted. It advocates the implementation of programs differentiated by life stage, the strengthening of primary prevention, and the inclusion of biographical antecedents in forensic psychological reports. This model offers a more complex, contextualized, and transformative understanding of gender violence, with high practical value for clinical, legal, and social settings.
