The Spanish daily El Correo published an article that refers to collaborative research with Dr. Mangan from the University of New Hampshire. In the paper (available from our site) Dr. Mangan and Dr. Reips show how Web surveys can reach members of rare populations and how beneficial Internet-based research can be particularly in interviewing people on sensitive topics. With their research they reached five times as many participants as were reached in all previous studies combined (from >20 years of research). The researched population were those directly or indirectly suffering from sexsomnia – for explanation see Website sleepsex.org by Dr. Mangan.
