As Internet accessibility and use increase dramatically, more and more people are turning to it for sexual purposes. This growing use of the Internet for sexual purposes indicates that the proportion of Internet sexual offences also will continue to rise dramatically. This article examines the impact of Internet problematic behaviours on the potential for recidivism among online sexual offenders. It argues for specialised treatment for these offenders whilst providing an overview of approaches that are currently used in other areas to treat problematic behaviours and how they could be used in the treatment of Internet sexual offenders. © 2013 Copyright Taylor and Francis Group, LLC.
