    "description": "Gaming disorder is commonly perceived as a condition that affects teenagers and young adults who spend excessive time playing video games — not a clinical disorder with diagnostic criteria recognized by a major international classification system. Adults who game heavily often dismiss the possibility of disorder because they maintain jobs and relationships, and because the cultural framing of adult gaming as a leisure activity insulates it from the scrutiny applied to adolescent gaming. The WHO's inclusion of gaming disorder in ICD-11 (effective 2022) remains contested in some academic quarters, creating a public impression that the diagnosis is either new, uncertain, or not a \"real\" disorder in the way substance-use disorders are — despite the ICD-11 criteria requiring functional impairment rather than merely heavy play.\n",

Factor A: The Entertainment Software Association (ESA) 2024 Essential Facts report found that 61% of Americans ages 5-90 play video games at least one hour per week, with 60% of adults (18+) playing every week. We use 0.60 as the prevalence of regular adult gamers in the US. Factor B: The Stevens, Dorstyn, Delfabbro, and King (2021) systematic review and meta-analysis in the Australian and New Zealand Journal of Psychiatry (corrected 2023) found a pooled prevalence of 2.96% of gamers meeting Gaming Disorder or equivalent criteria. The WHO and Stevens et al. cite a range of 1.4%–3.3% across studies; we use 2.0% as a conservative mid-range point estimate for the adult gamer subpopulation, noting that adolescent-weighted samples may inflate the global figure. Combined: 0.60 × 0.020 = 0.012. The current prevalence of ~2-3% among gamers approximates lifetime incidence for a disorder that often develops in early adulthood and may resolve; however, gaming disorder in adults is frequently comorbid with mood and anxiety disorders, which prolongs the clinical course. Uncertainty range: 0.006 (0.60 × 1.0% lower prevalence bound) to 0.024 (0.60 × 4.0% accounting for methodological heterogeneity and possible underdiagnosis). Note that lifetime_us_adult (0.012) is strictly inside low (0.006) and high (0.024).\n",

Because many included studies used adolescent or mixed-age samples, the adult-specific prevalence may differ from the pooled figure; the normalized estimate uses 2.0% as a more conservative adult-specific rate to account for this.

Critically, the ICD-11 criteria require \"significant impairment\" — gaming disorder is not the same as heavy gaming. This distinction is load-bearing for the normalized estimate: the 2–3% figure excludes heavy gamers who maintain functional lives, capturing only those with measurable life-domain impairment. The 12-month minimum duration criterion further filters out transient heavy play during exceptional circumstances (e.g., pandemic lockdowns).\n"

  "caveats": "Gaming disorder prevalence estimates vary substantially across studies (1.4%–3.3% in the WHO synthesis) depending on the assessment tool, the gaming population sampled, and whether ICD-11 or DSM-5 IGD criteria are applied. The DSM-5 includes Internet Gaming Disorder only as a \"condition for further study\" rather than a full diagnosis — a distinction that reflects ongoing scientific debate about diagnostic criteria rather than the absence of clinical phenomena. The current entry uses ICD-11 (WHO) criteria, which became effective internationally in 2022. A 2023 corrigendum to the Stevens et al. meta-analysis corrected the pooled prevalence from 3.05% to 2.96%, a small but methodologically important correction. The 12-month ICD-11 duration criterion means the current prevalence figure approximates lifetime incidence better than it would for conditions with very low spontaneous remission rates; gaming disorder has a documented recovery trajectory with or without formal treatment. Adults with gaming disorder frequently carry comorbid psychiatric diagnoses (depression, ADHD, social anxiety) that complicate attributing harm to gaming specifically. This entry is distinct from screen-time-teen-harm and screen-time-school-age-harm, which address developmental outcomes in younger cohorts.\n",
