Understanding Homicidal Ideation in Intimate Partner Homicide : A Scoping Review Restricted; Files Only
Dessalegn, Bisrat Kubi (Spring 2026)
Abstract
Introduction: Intimate partner homicide (IPH) is the most lethal manifestation of gender‑based violence, accounting for approximately 38% of female homicides worldwide. While intimate partner violence (IPV) has been widely studied, prevention efforts for homicide remain largely reactive. Existing risk‑assessment tools emphasize demographic and situational indicators yet rarely examine the internal psychological trajectories of perpetrators. As a result, a critical gap persists in understanding how violent thoughts evolve into lethal behavior. Emerging evidence suggests that perpetrators’ homicidal ideation may serve as an underutilized early warning signal. However, current research is fragmented and often relies on behavioral proxies rather than direct insights into perpetrators’ cognition.
Methods: A comprehensive literature search was conducted across five databases (PubMed, EMBASE, PsycINFO, Web of Science, and CINAHL) using controlled vocabulary and free‑text terms related to intimate partner homicide, homicidal ideation, and perpetrator psychology. After deduplication, 4,121 records were screened by four independent reviewers using predefined inclusion criteria. 97 full‑text articles were assessed, and 9 studies met inclusion criteria, excluding those lacking ideation‑related data or unrelated to IPH. Data extraction focused on study design, and ideation themes. Methodological quality was appraised using the JBI Checklist for Qualitative Research.
Results: The scoping review of nine studies published between 2005 and 2024 revealed a multi‑stage pathway of homicidal ideation in IPH perpetrators. Three core stages were identified: (1) Initiation, where ideation arose from entitlement, jealousy, and perceived loss of control, commonly triggered by relationship conflict or separation; (2) Formation, characterized by obsessive rumination, violent fantasy, and cognitive distortions that consolidated intent; and (3) Transition to Action, marked by planning, premeditation, and behavioral “leakage,” or external communication of intent. Contextual factors particularly access to weapons and systemic failures consistently heightened risk across stages.
Recommendations and Conclusion: Further empirical research is needed to identify, describe, and operationalize the cognitive processes associated with IPH perpetration. Integrating ideational indicators alongside existing lethality assessments may enhance early detection of escalating risk, particularly during high‑risk periods such as separation. Survivors, advocates, and law enforcement may use these insights to strengthen safety planning, recognize warning signs earlier, and intervene more effectively to prevent lethal outcomes.
