This study examines the impact of gender and sexism on police officers’ attitudes toward policing intimate partner violence (IPV). Data were collected from 826 Chinese police officers through online questionnaires. A hierarchical multiple regression analysis found that male police officers and those with sexist attitudes believe that handling IPV cases is illegitimate; they tend to perceive that the police are not morally bound to regulate such cases. Meanwhile, policewomen are less likely to consider that IPV interventions are difficult and resource-intensive. Findings indicate the need to amend policies and practices concerning gender and sexism among police officers to control IPV.
