This study conducted between November 2014 and October 2015 and published in 2018, examines intimate partner sexual violence (IPSV) among women in antenatal care and general outpatient settings in Thailand, focusing on its prevalence and association with femicide risk, suicidality, and substance use. Out of 14,288 women screened across nine hospitals in central Thailand, 207 who tested positive for intimate partner violence (IPV) participated. The findings reveal that 27.5% experienced sexual violence in the past 12 months, often co-occurring with psychological abuse (82.1%), physical violence (67.1%), and suicidal behaviour (17.6%). IPSV was linked to severe risk factors such as increased physical violence, threats to kill, and coercive control, emphasizing the urgent need for intervention. This research is particularly relevant to Thailand but has broader implications for addressing IPV globally. It highlights the critical role of healthcare providers in screening and managing IPV cases while underscoring the need for legal protections and mental health support for affected women. These findings inform policymakers and healthcare professionals on the importance of integrating targeted interventions to mitigate the impact of IPSV.
