Peace At Last Or Just A Piece Of Paper? Assessing The Utilization Of Civil Protection Orders And Reported Violations, Jennifer Medel

Dissertations

Over the past 50 years, attention to domestic violence as a social problem has grown substantially. With this heightened interest, remedies available to survivors have evolved in both scope and access. One popular avenue of help-seeking concerns civil protection orders (POs), which attempt to prevent subsequent abuse by setting conditions that regulate future interaction between abusers and survivors. Abusers, unfortunately, often violate POs with estimates of cases with violations ranging from 40 to 60%. Relatively little research, however, has examined the nature and determinants of PO violations using court records.

This dissertation addresses these little-studied issues by exploring variations in …
