Internet Gaming Disorder and Social Network Use Disorder

In 2013, the American Psychiatric Association included internet gaming disorder (IGD) in the appendix of the fifth version of the Diagnostic and Statistical Manual for Mental Disorders (DSM-5) as a condition warranting further research. This has led to a rapid increase of research on addictive internet activities. However, further evaluation of the criteria for IGD and social network disorder (SND) is needed.

In previous studies, we found that the pathological use of Internet games and social networks shares similarities with substance-related disorders (e.g., laterality, criteria for addiction; Bouna-Pyrrou et al. 2015). Moreover, we detected lower 2D:4D values in pathological video game players than in healthy control subjects. These results suggest that intrauterine sex hormone exposure modulates the risk for later pathological use of Internet games and social networks (Kornhuber et al. 2013). Most recently, we demonstrated good internal consistency, construct validity, retest-reliability, and long-term stability of SND and IGD criteria in German-speaking cohorts. Our data support good psychometric properties of the SND and IGD criteria and outline the addictive potential of social networking sites (Bouna-Pyrrou et al. 2018).
