This study aimed to examine the prevalence of nomophobia and of potential variables associated with the phenomenon. Additionally, it sought to determine if the average of total nomophobia and the four second-order factors differed across gender. Finally, it analyzed the associations between nomophobia (overall and second-order factors) and psychological variables (self-esteem, loneliness, life satisfaction, and phubbing behavior), internet use, and sociodemographic characteristics. A cross-sectional survey was conducted with 306 participants (68.6% women), aged between 18 and 79 years (M = 38.0, SD = 16.3), using an online questionnaire. Descriptive statistics, independent samples t-tests comparing groups by gender, and bivariate correlations were computed. After, multiple linear regression analyses were performed to obtain parsimonious models with the most relevant variables (psychological variables, internet use, and sociodemographic characteristics) associated with overall nomophobia and its four dimensions. The results were generally consistent with the previous literature. Notably, gender and phubbing behavior were significantly associated with nomophobia. These findings contribute to a better understanding of the nomophobia phenomenon and may inform future interventions aimed at mitigating its potential impact on well-being.<\/jats:p>","DOI":"10.3390\/ijerph22101495","type":"journal-article","created":{"date-parts":[[2025,9,29]],"date-time":"2025-09-29T10:49:34Z","timestamp":1759142974000},"page":"1495","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Nomophobia and Its Predictors: The Role of Psychological, Sociodemographic, and Internet Use Factors"],"prefix":"10.3390","volume":"22","author":[{"given":"In\u00eas Saraiva","family":"Ferreira","sequence":"first","affiliation":[{"name":"Health Sciences Faculty, Universidade Europeia, 1500-210 Lisboa, Portugal"},{"name":"Faculdade de Psicologia, Universidade de Lisboa, 1649-013 Lisboa, Portugal"},{"name":"Center for Research in Neuropsychology and Cognitive and Behavioral Intervention (CINEICC), PsyAssessmentLab, Universidade de Coimbra, 3001-401 Coimbra, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8507-8859","authenticated-orcid":false,"given":"Bel\u00e9n","family":"Rando","sequence":"additional","affiliation":[{"name":"Centre for Public Administration and Public Policies (CAPP), Institute of Social and Political Sciences, Universidade de Lisboa, 1300-663 Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ant\u00f3nio","family":"Esteves","sequence":"additional","affiliation":[{"name":"Health Sciences Faculty, Universidade Europeia, 1500-210 Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Milena","family":"Castro","sequence":"additional","affiliation":[{"name":"Health Sciences Faculty, Universidade Europeia, 1500-210 Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"In\u00eas","family":"Xavier","sequence":"additional","affiliation":[{"name":"Health Sciences Faculty, Universidade Europeia, 1500-210 Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4067-0386","authenticated-orcid":false,"given":"Ana Maria","family":"Abreu","sequence":"additional","affiliation":[{"name":"Insight, Piaget Research Center for Ecological Human Development, 2805-059 Almada, Portugal"},{"name":"Center for Interdisciplinary Research in Health (CIIS), Universidade Cat\u00f3lica Portuguesa, 1500-210 Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e63431","DOI":"10.2196\/63431","article-title":"Understanding Problematic Smartphone and Social Media Use Among Adults in France: Cross-Sectional Survey Study","volume":"12","author":"Karila","year":"2025","journal-title":"JMIR Ment.
