This study investigated the prevalence of problematic Internet pornography viewing, how it is problematic, and the psychological processes that underlie the problem in a sample of 84 college-age males using an anonymous online survey. It was found that approximately 20 percent-60 percent of the sample who view pornography find it to be problematic depending on the domain of interest. In this study, the amount of viewing did not predict the level of problems experienced. Mediational analyses suggest that the manner in which an individual interacts with urges to view pornography may be related to whether viewing is problematic or not.
