The urgency of responding to this worldwide pandemic has accelerated the development of monitoring systems and contact tracing applications. Without technology\u2019s contribution, the adverse effects on humanity economically, socially, and psychologically would be even more devastating. This study aimed to translate, adapt, and validate the Unified Theory of Acceptance and Use of Technology (UTAUT) model in a Portuguese university population, to evaluate adherence to a mobile application for tracking COVID-19. An observational cross-sectional study was developed using a sample with 1081 participants (71% female, 59.2% with ages between 16 and 24, and 78.2% of the respondent\u2019s university students). The Portuguese version model showed a good reliability (Cronbach\u2019s \u03b1 = 0.82) and an acceptable overall adjustment to the sample under study (\u03c72\/df = 3.732, CFI = 0.955, TLI = 0.944, RMSEA = 0.05, SRMR = 0.06); however, this model could be improved, as we proved. Since this is a pilot study, more studies are needed. The results indicated that the P-UTAUT can be improved for evaluating adherence to a COVID-19 mobile application.<\/jats:p>","DOI":"10.3390\/healthcare11131916","type":"journal-article","created":{"date-parts":[[2023,7,4]],"date-time":"2023-07-04T01:38:32Z","timestamp":1688434712000},"page":"1916","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Portuguese Validation of the Unified Theory of Acceptance and Use of Technology Scale (UTAUT) to a COVID-19 Mobile Application: A Pilot Study"],"prefix":"10.3390","volume":"11","author":[{"given":"Ivandra","family":"Ara\u00fajo","sequence":"first","affiliation":[{"name":"ESTeSL\u2014Escola Superior de Tecnologia da Sa\u00fade, Instituto Polit\u00e9cnico de Lisboa, Av.
