Further, there is even less research on how gender is associated with this relationship. The goal of the study was to examine adolescent screen use, PIU, and its impact on day-to-day routines of adolescents.Methods Participants were recruited from an outpatient pediatric clinic in S\u00e3o Paulo, Brazil. A total of 180 adolescents completed questionnaires related to their screen use, extracurricular activities, and symptoms of PIU. Univariate and multivariate statistics were used to determine correlates and predictors of PIU, and to explore gender differences.Results A total of 26.1% of adolescents met the criteria for PIU. There were no significant differences between boys and girls in PIU severity. However, there were significant gender differences in preferred use of the Internet, with boys being more likely to access the Internet to play video games (odds ratio [OR]=27.1) and girls being more likely to socialize with friends (OR=4.51). PIU severity increased proportionally to the number of hours of use of all screen devices with moderate-to-large effect sizes (\u03b72=0.060\u20130.157). Using screens during meals and missing extracurricular activities were both associated with PIU.Conclusion Though gender was not associated with PIU, both excessive use of screen devices during meals and neglect of offline extracurriculars activities were identified as risk factors for PIU. Prevention measures should consider the impact of gender and associated patterns of motivation and Internet use.<\/jats:p>","DOI":"10.30773\/pi.2023.0178","type":"journal-article","created":{"date-parts":[[2024,1,11]],"date-time":"2024-01-11T00:20:03Z","timestamp":1704932403000},"page":"18-27","update-policy":"https:\/\/doi.org\/10.30773\/crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Adolescent Screen Use: Problematic Internet Use and the Impact of Gender"],"prefix":"10.30773","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5017-4680","authenticated-orcid":true,"given":"Sheila Rejane","family":"Niskier","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1443-4611","authenticated-orcid":true,"given":"Lindsey A.","family":"Snaychuk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0804-0256","authenticated-orcid":true,"given":"Hyoun S.","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9171-9439","authenticated-orcid":true,"given":"Thiago T.","family":"da Silva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9405-4250","authenticated-orcid":true,"given":"Maria Sylvia","family":"de Souza Vitalle","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6632-2745","authenticated-orcid":true,"given":"Hermano","family":"Tavares","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"12228","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1556\/jba.2.2013.008"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1176\/appi.psychotherapy.1996.50.4.417"},{"key":"ref3","volume-title":"Number of smartphone mobile network subscriptions worldwide from 2016 to 2022, with forecasts from 2023 to 2028 [Internet]"},{"key":"ref4","first-page":"10","volume-title":"The effectiveness of prevention programs for problematic internet use in adolescents and youths: a systematic review and meta-analysis","author":"Saletti","year":"2021"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1186\/s12889-022-13155-3"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.12740\/pp\/66954"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.4088\/jcp.10m06057"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1007\/s11218-020-09601-y"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.4324\/9781351200677-3"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.24193\/jebp.2020.1.2"},{"key":"ref11","first-page":"1","volume-title":"Extracurricular activities","author":"Lunenburg","year":"2010"},{"key":"ref12","volume-title":"Teens, social media and technology 2018 [Internet]"},{"key":"ref13","first-page":"5","volume-title":"Does the construct of internet addiction reflect a single entity or a spectrum of disorders?","author":"Starcevic","year":"2017"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph15122913"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016\/j.cpr.2022.102128"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016\/j.chb.2020.106480"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1080\/13575279.2021.1887815"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1177\/00016993211008500"},{"key":"ref19","first-page":"49","volume-title":"\u201cHyperconnected\u201d adolescents: sedentary screen time according to gender and type of day","author":"Simon-Monta\u00f1es","year":"2019"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1177\/0033294120922481"},{"key":"ref21","first-page":"e653","volume-title":"Longitudinal trajectories, social and individual antecedents, and outcomes of problematic internet use among late adolescents","author":"T\u00f3th-Kir\u00e1ly","year":"2021"},{"key":"ref22","first-page":"1031","volume-title":"What types of internet services make adolescents addicted?
