A conceptual understanding of intimate partner violence behaviors in men: Implications for research and intervention

Abstract

Intimate Partner Violence (IPV) is a significant public health concern globally with substantial impact on the health of victims. Although research on IPV has increased substantially over the past several decades, effective evidence-based interventions to address IPV behaviors by men remain limited. The IPV field has lacked a comprehensive review of the status of research across the broad areas that have been found to be associated with use of IPV behaviors. This paper reviewed quantitative research studies of the genetic, neurocognitive, neuroendocrine, and selected environmental underpinnings of IPV behavior in men to develop a conceptual model. To date, environmental studies have been the most extensive with focus on early life adversity, trauma, attachment and substance misuse. Head injuries and neuropsychological impacts have indicated deficits in cognitive flexibility and executive functioning related to the prefrontal cortex are common in men who use IPV. Fewer studies have examined neuroendocrine or hormonal factors impacting IPV behavior but there is some evidence that cortisol and testosterone may play a role. Genetics factors have been the least explored, although there is emerging evidence of genetic heritability, and gene by environment interactions. A more comprehensive understanding of biological, psychological, and social factors will advance future IPV research and intervention.
