Internet gaming disorder (IGD) is a serious disorder leading to and
maintaining pertinent personal and social impairment. IGD has to be considered in
view of heterogeneous and incomplete concepts. We therefore reviewed the
scientific literature on IGD to provide an overview focusing on definitions,
symptoms, prevalence, and aetiology. METHOD: We systematically reviewed the
databases ERIC, PsyARTICLES, PsycINFO, PSYNDEX, and PubMed for the period January
1991 to August 2016, and additionally identified secondary references. RESULTS:
The proposed definition in the Diagnostic and Statistical Manual of Mental
Disorders, Fifth Edition provides a good starting point for diagnosing IGD but
entails some disadvantages. Developing IGD requires several interacting internal
factors such as deficient self, mood and reward regulation, problems of
decision-making, and external factors such as deficient family background and
social skills. In addition, specific game-related factors may promote IGD.
Summarizing aetiological knowledge, we suggest an integrated model of IGD
elucidating the interplay of internal and external factors. INTERPRETATION: So
far, the concept of IGD and the pathways leading to it are not entirely clear. In
particular, long-term follow-up studies are missing. IGD should be understood as
an endangering disorder with a complex psychosocial background. WHAT THIS PAPER
ADDS: In representative samples of children and adolescents, on average, 2% are
affected by Internet gaming disorder (IGD). The mean prevalences (overall,
clinical samples included) reach 5.5%. Definitions are heterogeneous and the
relationship with substance-related addictions is inconsistent. Many aetiological
factors are related to the development and maintenance of IGD. This review
presents an integrated model of IGD, delineating the interplay of these factors.
