Project description

This multi-method, interdisciplinary research project investigates the causes, development and prevalence of video game addiction together with the clinical relevance of other forms of psychological dependence in connection with the use of interactive entertainment media.

The study design features closely related quantitative and qualitative methodological approaches. The subject of the quantitative part of the investigation is a longitudinal study of media dependency in 7th to 10th grade school students and a representative nationwide survey of the 16-49 age group. The subject of the qualitative study modules consists of in-depth interviews with normal, excessive, at-risk and addicted players and a structural analysis of relevant games for inherent addictive attributes.

The expertise gained in the project is to be used to develop a diagnostic standard for media dependency that corresponds to the clinical classification system. This involves developing the KFN-CSAS-II video game addiction scale into a multidimensional, adaptive diagnostic tool to identify addictive individual media usage. The project outcomes will also be used to develop guidance for video game content rating systems so that game attributes indicative of heightened psychotropic addiction risk can be taken into account in age ratings.
