Does the Decriminalization of Prostitution Reduce Rape and Sexually Transmitted Disease? A Review of Cunningham and Shah Findings

Abstract

In 2013, research findings by Cunningham and Shah claimed that rape and sexually transmitted diseases were reduced by decriminalized prostitution in Rhode Island. The original unpublished claims have received wide media coverage which have gone unexamined. This review finds errors in their analyses. One error is the date when prostitution was decriminalized in Rhode Island. Cunningham and Shah claim that prostitution was decriminalized in 2003. Our analysis finds the date of decriminalization of prostitution was 1980. The change in the start date of decriminalization significantly alters the analysis and the findings. Another error results from Cunningham and Shah using an outlier data point to define a period of analysis. The results of this review call into question the claims that the decriminalization of prostitution reduced rape and sexually transmitted disease.
