MedicalResearch.com Interview with: John W. Ayers, PhD, MA Altman Clinical Translational Research Institute University of California San Diego, La Jolla MedicalResearch.com: What is the background for this study? Response: Crisis pregnancy centers (CPCs) are frequently at the center of news and policy debates, yet little data exists about where they operate or what they actually do. To address this gap, we developed ChoiceWatch.org, a tool that systematically collected and analyzed over 470,000 webpages from CPC websites. In our study published in JAMA Internal Medicine, we used ChoiceWatch.org, to answer fundamental questions, such as how many crisis pregnancy centers operate in the U.S., where they are located, and what services they advertise.
