This chapter examines psychological theories that explain the causes and perpetuation of family violence by integrating individual, relational, and sociocultural perspectives. It begins with psychoanalytic frameworks, emphasizing how early childhood experiences, unconscious processes, personality development, and attachment styles shape relational patterns that may contribute to abuse. The discussion then turns to social learning theory, which highlights how violent behaviors are observed, reinforced, and transmitted interpersonally. Intergenerational frameworks further extend this perspective by exploring how trauma and violence are perpetuated across generations through behavioral modeling, psychological mechanisms, and epigenetic pathways. Neurobiological theories provide additional insights into the role of brain structures and functions, including executive function, impulse control, and emotional regulation, in mediating both reactive and proactive forms of aggression. The chapter also engages critiques of each theoretical approach, including limitations of explanatory power, empirical challenges, and the need for attention to broader systemic and structural factors. Taken together, these psychological theories provide a comprehensive lens for identifying risk factors, understanding the persistence of violence, and informing prevention and intervention strategies that target both individual development and relational dynamics.
