Nonetheless, little is known about the clinical prevalence of IGD in children and adolescents. Additionally, it is unclear if patients with IGD are already identified in routine psychotherapy, using the ICD-10 diagnosis F 63.8 (recommended classification of IGD in ICD-10). This study investigated N = 358 children and adolescents (self and parental rating) of an outpatient psychotherapy centre in Germany using the Video Game Dependency Scale. According to self-report 4.0% of the 11- to 17-year-old patients met criteria for a tentative IGD diagnosis and 14.0% according to the parental report. Of the 5- to 10-year-old patients, 4.1% were diagnosed with tentative IGD according to parental report. Patients meeting IGD criteria were most frequently diagnosed with hyperkinetic disorders, followed by anxiety disorders, F 63.8, conduct disorders, mood disorders and obsessive-compulsive disorders (descending order) as primary clinical diagnoses. Consequently, this study indicates that a significant amount of the clinical population presents IGD. Meaning, appropriate diagnostics should be included in routine psychological diagnostics in order to avoid \u201chidden\u201d cases of IGD in the future.<\/jats:p>","DOI":"10.3390\/ijerph18136787","type":"journal-article","created":{"date-parts":[[2021,6,24]],"date-time":"2021-06-24T11:01:38Z","timestamp":1624532498000},"page":"6787","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Estimated Prevalence of Unreported IGD Cases in Routine Outpatient Children and Adolescent Psychotherapy"],"prefix":"10.3390","volume":"18","author":[{"given":"Sonja","family":"Kewitz","sequence":"first","affiliation":[{"name":"Institute of Psychology, Goethe University Frankfurt, 60323 Frankfurt am Main, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eva","family":"Vonderlin","sequence":"additional","affiliation":[{"name":"Centre for Psychological Psychotherapy Heidelberg, Heidelberg University, 69115 Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lutz","family":"Wartberg","sequence":"additional","affiliation":[{"name":"Department of Psychology, Faculty of Human Sciences, MSH Medical School Hamburg, 20457 Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7415-9856","authenticated-orcid":false,"given":"Katajun","family":"Lindenberg","sequence":"additional","affiliation":[{"name":"Institute of Psychology, Goethe University Frankfurt, 60323 Frankfurt am Main, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,24]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2020, August 13).
