This study examined stalking prevalence, patterns, and harm among 210 women with civil protective orders (PO) against violent male partners or ex-partners. Results suggest that stalking is associated with PO violations and almost every other type of partner violence. Also, women who have been stalked by violent partners report significantly more distress and harm than even women who experience PO violations but not stalking. Results of key informant perceptions suggest many victim service (n=116) and criminal justice professionals (n=72) do not seem to understand the extent or gravity of the harms caused by partner stalking especially when contrasted with victim reports of harm. Furthermore, key informant reports of their advice to women being stalked by an ex-partner were not consistent with recommendations for stalking victims in general. (Published Abstract)
