Using a representative sample of 7,027 Canadian women living in a marital or common-law union, this investigation examined the risk for partner violence against women with disabilities relative to women without disabilities. Women with disabilities had 40% greater odds of violence in the 5 years preceding the interview, and these women appeared to be at particular risk for severe violence. An explanatory framework was tested that organized variables based on relationship factors, victim-related characteristics, and perpetrator-related characteristics. Results showed that perpetrator-related characteristics alone accounted for the elevated risk of partner violence against women with disabilities. Stakeholders must recognize the problem of partner violence against women with disabilities, and efforts to address patriarchal domination and male sexual proprietariness appear crucial to reducing their risk of partner violence.
