Moreover, health literacy levels decrease with increasing age.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n The aim of this study is to assess an app\u2019s utility in promoting health-related knowledge in people aged \u226565 years.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n We developed a simple, intuitive, and video-based app (DigiAdherence) that presents a recipe, nutritional counseling, and content on physical activity, cognitive exercise, motivation to adhere to treatment, fall prevention, and health literacy. A convenience sample of 25 older adults attending the Personalized Health Care Unit of Portim\u00e3o or the Family Health Unit of Portas do Arade (ACeS Algarve II \u2013 Barlavento, ARS Algarve, Portugal) will be recruited. Subjects must be aged \u226565 years, own a smartphone or tablet, be willing to participate, and consent to participate. Those who do not know how to use or do not have a smartphone\/tablet will be excluded. Likewise, people with major cognitive or physical impairment as well as those living in a long-term care center will not be included in this study. Participants will have access to the app for 4 weeks and will be evaluated at 3 different timepoints (V0, before they start using the app; V1, after using it for 30 days; and V2, 60 days after stopping using it). After using the app for 30 days, using a 7-point Likert scale, participants will be asked to score the mobile tool\u2019s utility in encouraging them to take their medications correctly, improving quality of life, increasing their health-related knowledge, and preventing falls. They will also be asked to assess the app\u2019s ease of use and visual esthetics, their motivation to use the app, and their satisfaction with the app. Subjects will be assessed in a clinical interview with a semistructured questionnaire, including questions regarding user experience, satisfaction, the utility of the app, quality of life (EQ-5D-3L instrument), and treatment adherence (Morisky scale). The proportion of participants who considered the app useful for their health at V1 and V2 will be analyzed. Regarding quality of life and treatment adherence perceptions, comparisons will be made between V0 and V1, using the t test for dependent samples. The same comparisons will be made between V0 and V2.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n This study was funded in December 2019 and authorized by the Executive Board of ACeS Algarve II \u2013 Barlavento and by the Ethics Committee of NOVA Medical School (99\/2019\/CEFCM, June 2020). This protocol was also approved by the Ethics Committee for Health (16\/2020, September 2020) and the Executive Board (December 2020) of the Regional Health Administration of the Algarve, IP (Instituto P\u00fablico). Recruitment was completed in June 2021.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Since the next generation of older adults may have higher digital literacy, information and communication technologies could potentially be used to deliver health-related content to improve lifestyles among older adults.<\/jats:p>\n <\/jats:sec>\n \n International Registered Report Identifier (IRRID)<\/jats:title>\n PRR1-10.2196\/29675<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/29675","type":"journal-article","created":{"date-parts":[[2022,5,26]],"date-time":"2022-05-26T16:42:01Z","timestamp":1653583321000},"page":"e29675","source":"Crossref","is-referenced-by-count":4,"title":["A Video-Based Mobile App as a Health Literacy Tool for Older Adults Living at Home: Protocol for a Utility Study"],"prefix":"10.2196","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6468-5681","authenticated-orcid":false,"given":"Catarina","family":"Nunes-Da-Silva","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1703-6248","authenticated-orcid":false,"given":"Andr\u00e9","family":"Victorino","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3261-7158","authenticated-orcid":false,"given":"Marta","family":"Lemos","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0069-9793","authenticated-orcid":false,"given":"Ludmila","family":"Porojan","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2727-4402","authenticated-orcid":false,"given":"Andreia","family":"Costa","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9183-9121","authenticated-orcid":false,"given":"Miguel","family":"Arriaga","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0380-7833","authenticated-orcid":false,"given":"Maria Jo\u00e3o","family":"Greg\u00f3rio","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9713-0204","authenticated-orcid":false,"given":"Rute Dinis","family":"de Sousa","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2046-8017","authenticated-orcid":false,"given":"Ana Maria","family":"Rodrigues","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1894-4870","authenticated-orcid":false,"given":"Helena","family":"Canh\u00e3o","sequence":"additional","affiliation":[]}],"member":"1010","published-online":{"date-parts":[[2022,12,7]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1136\/bmj.l1","year":"2019","journal-title":"BMJ"},{"key":"ref2","first-page":"1","author":"Marta, Barreto","year":"2016","journal-title":"1\u00ba Inqu\u00e9rito Nacional de Sa\u00fade com Exame F\u00edsico (INSEF 2015): Estado de Sa\u00fade"},{"journal-title":"Portugal: Country Health Profile 2019, State of Health in the EU","year":"2019","key":"ref3"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.20344\/amp.9817"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1002\/agm2.12045"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.arr.2011.03.003"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007\/s00228-014-1780-0"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1097\/00005650-200205000-00005"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.3122\/jabfm.17.1.44"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.2105\/ajph.92.8.1278"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1007\/s11606-015-3206-9"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1177\/2055668317696236"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1177\/1357633X18790170"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijhcs.2008.03.002"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.3389\/fdgth.2020.00015"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.2196\/jmir.3269"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.2196\/resprot.6626"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.2196\/26871"},{"key":"ref19","unstructured":"Telo-de-ArriagaMiguelSantosBenvindaSilvaAndreiaMataFranciscoChavesNicoleFreitasGra\u00e7aPlano de a\u00e7\u00e3o para a literacia em sa\u00fade 2019-2021 -
