The present study investigated the association between autism and problematic internet use (PIU) and gaming disorder (GD). A systematic literature search was conducted in accordance with PRISMA guidelines. A total of 2286 publications were screened, and 21 were deemed eligible for inclusion in the review. The majority of the studies found positive associations between PIU and subclinical autistic-like traits with weak and moderate effect sizes and between PIU and Autism Spectrum Disorder (ASD) with varying effect sizes. Additionally, individuals with ASD were more likely to exhibit symptoms of GD with moderate and strong effect sizes. Future research would benefit from high-quality studies examining GD and PIU at a clinical level and their relationship with both clinical and subclinical autism.

Gaming disorder (GD) is a clinical addiction to video or internet games. This study investigated whether GD symptoms are heightened in adults with autism spectrum disorder (ASD) in comparison to a control group, and explored predictors of GD in 230 adults with ASD and 272 controls. The relationship between GD and gelotophobia was examined. Measures included the Ten-Item Internet Gaming Disorder Test, GELOPH < 15 >, Autism Spectrum Quotient-10 items, Inventory of Parent and Peer attachment, Emotional Regulation Questionnaire, Social Functioning Questionnaire (SFQ) and the NEO-FFI-3. Individuals in the ASD group showed significantly higher symptoms of GD. Peer-attachment, emotional regulation and extraversion significantly predicted GD scores. Gelotophobia and GD were related to each other with a small effect size.
