Sources: 5. Developments: 2. Marieke Liem, a professor of Safety and Intervention Studies at Leiden University, has released research findings through the Femicide Monitor regarding support for victims of severe partner violence. The research, which involved interviews with dozens of victims, highlights that it often takes more than 30 incidents before a victim seeks professional assistance. Because acquaintances—including neighbors, friends, colleagues, and family—frequently recognize patterns of coercive control earlier than the victim, they are considered crucial for intervention. Liem identified five key recommendations for bystanders to support those in unsafe relationships: initiating a conversation to acknowledge the situation, avoiding judgment, providing practical support, maintaining consistent contact, and allowing the victim to maintain control over their own decisions. ## Timeline ### 2026-09-27: Leiden University research offers tips for supporting victims of unsafe relationships Professor Marieke Liem provides five practical tips for bystanders to support individuals in unsafe or controlling relationships, noting that observers often recognize patterns before victims seek help. 2 sources. https://clstr.news/cluster/leiden-university-research-offers-tips-for-supporting-victims-of-unsafe-relationships ### 2026-09-24: Professor shares five tips to support victims of partner violence Professor Marieke Liem shares five research-based tips for supporting people in unsafe relationships, noting that acquaintances often recognize patterns of coercive control before victims seek professional help 3 sources. https://clstr.news/cluster/professor-shares-five-tips-to-support-victims-of-partner-violence --- Cite as: Leiden University research on partner violence intervention.
