BACKGROUND: Gaming disorder (GD), i.e., persistent problematic gaming with clinically significant impairment, is a growing concern; however, estimates of GD in representative adolescent samples are limited. This study aimed to examine GD prevalence, incidence, persistence, and risk factors for different epidemiological parameters across 6 years, covering pre- to post-COVID-19 pandemic.
METHODS: Population-based longitudinal data, including 3358 German adolescents, were collected annually from 2019 to 2024 using online surveys. GD prevalence estimates were assessed by standardized International Classification of Diseases (ICD-11)-based self-report questionnaires. Between-wave persistence and incidence of GD, sociodemographic data, gaming time, and stress perception were measured. Risk factors for incidence and persistence of GD were examined using generalized-estimating equation (GEE) models.
RESULTS: GD prevalence doubled from 2.9% in 2019 to 6.5% in 2023 and remained above prepandemic levels in 2024 (3.9%). Males showed higher prevalence estimates compared to females across most waves, and prevalence peaked in 2023 (8%). For females, GD prevalence doubled between 2019 (1.7%) and 2020 (3.4%), peaked in 2022 (6.1%), and declined thereafter. The incidence of GD increased during the pandemic. According to GEE models, male sex, higher perceived stress, and longer gaming times were risk factors for GD incidence; older age and higher education were protective factors. The persistence of GD reached its peak in 2020 (36.2%). Significant risk factors for GD persistence were higher stress perception and longer gaming time.
CONCLUSIONS: Prevalence and incidence rates indicate that GD continues to be a significant concern, and pandemic-related increases affected both males and females. Prevention and intervention programs should target identified risk groups.
