Cognitive characteristics of intimate partner violence (IPV) offenders have received considerable attention recently. The implicit theories underlying these cognitions have yet to be evidenced using accounts of IPV males. In this study, interpretative phenomenological analysis was used to analyze interview transcripts of six IPV offenders currently serving a custodial sentence in a Scottish prison to identify potential implicit theories. Analyses resulted in the identification of 11 potential implicit theories of IPV: "violence is acceptable;" "grievance/revenge;" "need for control;" "real man;" "entitlement/women are objects;" "male sex drive is uncontrollable/policing partner;" "women are provoking;" "rejection/abandonment;" "women as supportive;" "external factors responsible;" and "nature of harm." The implicit theories are compared across other groups of offender and implications for offender interventions discussed. Abstract published by arrangement with Springer.
