Primary outcomes included overall screen media use, emotional state (assessed by the Depression, Anxiety, and Stress Scale for Youth, DASS-Y), and sleep quality (assessed by the Pittsburgh Sleep Quality Index, PSQI).<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Analysis of 48,432 complete responses revealed that 36.5% of participants reported a daily screen time of 30 min to 1 h, while 11.3% reported more than 4 h per day. The partial least squares structural equation modeling (PLS-SEM) indicated that screen time was positively associated with PSQI global score (\u03b2 = 0.116,\n p<\/jats:italic>\n &lt; 0.001), depression (\u03b2 = 0.047,\n p<\/jats:italic>\n &lt; 0.001) and stress (\n p<\/jats:italic>\n = 0.075,\n p<\/jats:italic>\n &lt; 0.001) scales. Study grade exhibited a significant inverse relationship with screen time (\u03b2 = \u22120.092,\n p<\/jats:italic>\n &lt; 0.001). Higher screen time was significantly correlated with older age (\u03b2 = 0.069,\n p<\/jats:italic>\n &lt; 0.001) and male gender (\u03b2 = \u22120.072,\n p<\/jats:italic>\n &lt; 0.001). Furthermore, both paternal (\u03b2 = \u22120.056,\n p<\/jats:italic>\n &lt; 0.001) and maternal (\u03b2 = \u22120.059,\n p<\/jats:italic>\n &lt; 0.001) education levels were significantly inversely related to screen time.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n The study identified significant associations between higher screen time, poorer sleep quality, and elevated depression and stress levels, highlighting the importance of promoting healthy screen-use behaviors and supporting adolescents\u2019 sleep quality and psychological well-being.<\/jats:p>\n <\/jats:sec>","DOI":"10.3389\/fpsyg.2026.1686399","type":"journal-article","created":{"date-parts":[[2026,9,11]],"date-time":"2026-09-11T05:28:57Z","timestamp":1789104537000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Screen time and its association with psychological wellbeing and sleep quality: overview of the Fujian Adolescent Mental Wellness Study (FAMWeS)"],"prefix":"10.3389","volume":"17","author":[{"given":"Yulan","family":"Lin","sequence":"first","affiliation":[{"name":"Fujian Key Laboratory of Environmental Factors and Cancer, Department of Epidemiology and Health Statistics, School of Public Health, Fujian Medical University, Fuzhou","place":["Fujian, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Emergency, Fuzhou University Affiliated Provincial Hospital, Fuzhou","place":["Fujian, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhijie","family":"Luo","sequence":"additional","affiliation":[{"name":"Fujian Key Laboratory of Environmental Factors and Cancer, Department of Epidemiology and Health Statistics, School of Public Health, Fujian Medical University, Fuzhou","place":["Fujian, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingying","family":"Wang","sequence":"additional","affiliation":[{"name":"Fujian Key Laboratory of Environmental Factors and Cancer, Department of Epidemiology and Health Statistics, School of Public Health, Fujian Medical University, Fuzhou","place":["Fujian, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fengqin","family":"Zou","sequence":"additional","affiliation":[{"name":"Fujian Key Laboratory of Environmental Factors and Cancer, Department of Epidemiology and Health Statistics, School of Public Health, Fujian Medical University, Fuzhou","place":["Fujian, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haridah","family":"Alias","sequence":"additional","affiliation":[{"name":"Centre for Population Health (CePH), Department of Social and Preventive Medicine, Faculty of Medicine, Universiti Malaya","place":["Kuala Lumpur, Malaysia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li Ping","family":"Wong","sequence":"additional","affiliation":[{"name":"Fujian Key Laboratory of Environmental Factors and Cancer, Department of Epidemiology and Health Statistics, School of Public Health, Fujian Medical University, Fuzhou","place":["Fujian, China"]},{"name":"Centre for Population Health (CePH), Department of Social and Preventive Medicine, Faculty of Medicine, Universiti Malaya","place":["Kuala Lumpur, Malaysia"]},{"name":"Department of Medicine, College of Medicine, Korea University","place":["Seoul, Republic of Korea"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhijian","family":"Hu","sequence":"additional","affiliation":[{"name":"Fujian Key Laboratory of Environmental Factors and Cancer, Department of Epidemiology and Health Statistics, School of Public Health, Fujian Medical University, Fuzhou","place":["Fujian, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,11]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1058","DOI":"10.1001\/jamapediatrics.2019.3176","article-title":"Association between screen media use and academic performance among children and adolescents: a systematic review and meta-analysis.","volume":"173","author":"Adelantado-Renau","year":"2019","journal-title":"JAMA Pediatr"},{"key":"B2","doi-asserted-by":"publisher","first-page":"204","DOI":"10.1111\/jhn.12147","article-title":"Association of dietary habits with levels of physical activity and screen time among adolescents living in Saudi Arabia.","volume":"27","author":"Al-Hazzaa","year":"2014","journal-title":"J.
