This research aims to identify the relationship and influence between levels of nomophobia and the age or educational stage of students. The research method is based on a correlational and predictive design of quantitative methodology. The instrument used is the NMP-Q questionnaire. The study population is students from different educational stages (obligatory secondary education, baccalaureate, vocational training and university). The results show that students over 12 years old present an average level of \u201cnomophobia\u201d (no-mobile-phone phobia), namely, not being able to communicate with the family where the highest levels are presented. We conclude that students over 12 years of age and of any educational stage present an average level of nomophobia, and it cannot be determined that either the educational stage or the age are determining factors in the presentation of this problem. This can occur at any age and at any level of the different educational stages, although there are risk indicators that we should bear in mind to avoid the appearance of nomophobia.<\/jats:p>","DOI":"10.3390\/ijerph18094450","type":"journal-article","created":{"date-parts":[[2021,4,22]],"date-time":"2021-04-22T13:59:14Z","timestamp":1619099954000},"page":"4450","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Do Age and Educational Stage Influence No-Mobile-Phone Phobia?"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3394-2777","authenticated-orcid":false,"given":"Antonio-Manuel","family":"Rodr\u00edguez-Garc\u00eda","sequence":"first","affiliation":[{"name":"Department of Didactics and School Organization, University of Granada, 52071 Melilla, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8623-4796","authenticated-orcid":false,"given":"Jos\u00e9-Antonio","family":"Mar\u00edn-Mar\u00edn","sequence":"additional","affiliation":[{"name":"Department of Didactics and School Organization, University of Granada, 18071 Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9881-9169","authenticated-orcid":false,"given":"Juan-Antonio","family":"L\u00f3pez-N\u00fa\u00f1ez","sequence":"additional","affiliation":[{"name":"Department of Didactics and School Organization, University of Granada, 18071 Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3191-2048","authenticated-orcid":false,"given":"Antonio-Jos\u00e9","family":"Moreno-Guerrero","sequence":"additional","affiliation":[{"name":"Department of Didactics and School Organization, University of Granada, 51001 Ceuta, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.chb.2019.03.037","article-title":"When The Smartphone Goes Offline: A Factorial Survey of Smartphone Users\u2019 Experiences Of Mobile Unavailability","volume":"98","year":"2019","journal-title":"Comput.
