[Excessive Use Patterns and Internet Use Disorders: Effects on Psychosocial and Cognitive Development in Adolescence]

The growing availability of digital technologies has led to increased rates of using them as a part of daily recreational activity among adolescents. Despite their positive effects, there are ongoing debates of potential harm and health-related negative consequences, particularly when internet activities are performed excessively. This contribution provides an overview on negative aspects of digital technologies by presenting a selection of empirical findings. This overview focuses on a selection of recent methodologically sound studies investigating potential negative effects of digital technologies on the development of adolescents. As main constructs, effects on psychosocial and cognitive development and internet use disorders were investigated. Recently published studies point to substantial associations between internet overuse and negative consequences. Habitual, intense use of the internet is related to higher rates of internalizing symptoms, cognitive distortions, and heightened rates of internet use disorders among adolescents. Given these findings it seems recommendable to provide a close parental monitoring of adolescents discovering virtual worlds. By applying clear rules and supporting development of media literacy, functional use habits can be empowered and harmful effects prevented.The new clinical phenomenon of internet use disorder and its high prevalence among adolescents represents a new challenge for treatment services.
