Edwards 2005 Journal of Computer-Mediated Communication 10 2 <p>In a web-based, sexual behavior risk study using a rigorous response validation protocol, we identified 124 invalid responses out of 1,150 total (11% rejection). Nearly all of these (119) were due to repeat survey submissions from the same participants, and 65 of them came from a single participant. This brief describes how we were able to detect these repeat submissions using the validation protocol, and highlights the importance of using both automated and manual validation techniques</p> http://jcmc.indiana.edu/vol10/issue2/konstan.html
