Three self\u2010reporting instruments were used: the Munich Chronotype Questionnaire, the Perceived Stress Scale, and the Pittsburgh Sleep Quality Index. Multivariate regression analysis was performed to investigate the influence of chronotype and perceived stress on sleep quality in undergraduates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Sixty\u2010one per cent of the respondents were poor\u2010quality sleepers. Moreover, 85.5% of the respondents were classified as \u201cneither\u201d chronotype, whereas 13.6% were \u201cevening\u201d chronotype. Sleep quality was associated with both chronotype and perceived stress level (<jats:italic>r<\/jats:italic>\u2009=\u20090.41, 0.43, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). Multiple regression revealed higher MCTQ scores (continuous or categorical) and higher perceived stress were significantly associated with poorer sleep quality, explaining approximately 30% of the variance (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The findings of this study showed evening\u2010type undergraduates with higher perceived stress exhibited poorer sleep quality. Highlight the importance of considering chronotype in health promotion among individuals transitioning to adulthood. Early interventions may help align an individual's chronotype with their external time schedule, mitigate the negative impacts of misaligned later chronotypes, enhance sleep quality, and help to manage perceived stress levels in undergraduates.<\/jats:p><\/jats:sec>","DOI":"10.1111\/eip.13641","type":"journal-article","created":{"date-parts":[[2024,12,24]],"date-time":"2024-12-24T11:04:01Z","timestamp":1735038241000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Role of Chronotypes and Perceived Stress on Sleep Quality in Undergraduates in Taiwan"],"prefix":"10.1111","volume":"19","author":[{"given":"Ren\u2010Rong","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Family Medicine, College of Medicine National Taiwan University  Taipei City Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5686-9296","authenticated-orcid":false,"given":"Jia\u2010Yin","family":"Syu","sequence":"additional","affiliation":[{"name":"Department of Nursing, College of Medicine National Cheng Kung University and Hospital  Tainan City Taiwan"},{"name":"Psychiatric Acute Ward, Chiayi Branch Taichung Veterans General Hospital  Chaiyi City Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeff Chien\u2010Ta","family":"Chen","sequence":"additional","affiliation":[{"name":"Centers for Disease Control Ministry of Health and Welfare  Taipei City Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5766-4586","authenticated-orcid":false,"given":"Sue Jane","family":"Fetzer","sequence":"additional","affiliation":[{"name":"Department of Nursing, College of Health and Service University of New Hampshire  Durham New Hampshire USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5134-1700","authenticated-orcid":false,"given":"Esther Ching\u2010Lan","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Nursing, College of Medicine National Cheng Kung University and Hospital  Tainan City Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,12,24]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10865\u2010022\u201000348\u20109"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.47391\/jpma.2087"},{"key":"e_1_2_7_4_1","doi-asserted-by":"crossref","unstructured":"Bojic I.
