As a result of the rise and implementation of Information and Communication Technologies (ICTs), in recent years we have documented an exponential growth in the percentage of young people and adults who use the Internet to access sexual content or to meet people with whom to maintain sexual contacts online or offline. Our first investigations on this topic aimed to estimate the magnitude of the phenomenon in young people, as well as to analyze the pattern of recreational consumption and its evolution towards addiction. Nowadays, our research interest is focused on exploring this phenomenon throughout all the stages of the lifespan (from childhood and adolescence to late adulthood), finding a risk profile that allows us to identify the most vulnerable people to develop an addiction, and propose therapeutic strategies that allow us to control engagement in online sexual activities. We have also developed an online platform for the assessment and treatment of cybersex addiction (to the best of our knowledge, the first one in the hispanic context). Furthermore, we have developed the first treatment program for this pathology and we are now analyzing its effectiveness.
