The PIDAQ was culturally translated and adapted according to international guidelines. In this cross-sectional study, we enrolled 501 subjects in a population-based epidemiological survey conducted at the Egas Moniz Dental Clinic (Almada, Portugal) in June 2022. The participants answered the Portuguese version of the PIDAQ (PIDAQ-PT), which was a 23-item scale with four conceptual domains (self-confidence, social impact, psychological impact and esthetic concern factor). Psychometric properties were estimated using content validity, construct validity, internal consistency and test\u2013retest reliability. The PIDAQ-PT presented an intraclass correlation coefficient (ICC) of 0.84, and a 95% confidence interval (0.73\u20130.90, p &lt; 0.001), with values for the Cronbach\u2019s alpha coefficient of the subconstructs ranging from 0.93 to 0.98. In the confirmatory factor analysis (CFA), the final models presented a good fit, with the comparative fit indices (CFIs) ranging from 0.905 to 0.921 and the root mean squared error of approximation (RMSEA) ranging between 0.088 and 0.090. The PIDAQ-PT was shown to be a valid and reliable tool to assess oral health values in a Portuguese population. Further studies should evaluate the psychometric properties of the oral personal representation on dental specialties and its impact on dental appointments and procedures.<\/jats:p>","DOI":"10.3390\/ijerph19169931","type":"journal-article","created":{"date-parts":[[2022,8,11]],"date-time":"2022-08-11T21:15:05Z","timestamp":1660252505000},"page":"9931","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Cross-Cultural Adaptation and Validation of the Portuguese Version of the Psychosocial Impact of Dental Aesthetics Questionnaire"],"prefix":"10.3390","volume":"19","author":[{"given":"Jo\u00e3o","family":"Fidalgo","sequence":"first","affiliation":[{"name":"Clinical Research Unit (CRU), Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz (CiiEM), Egas Moniz Cooperativa de Ensino Superior, 2829-511 Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1019-8263","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Botelho","sequence":"additional","affiliation":[{"name":"Clinical Research Unit (CRU), Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz (CiiEM), Egas Moniz Cooperativa de Ensino Superior, 2829-511 Almada, Portugal"},{"name":"Evidence-Based Hub, Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz (CiiEM), Egas Moniz Cooperativa de Ensino Superior, 2829-511 Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8482-5936","authenticated-orcid":false,"given":"Lu\u00eds","family":"Proen\u00e7a","sequence":"additional","affiliation":[{"name":"Clinical Research Unit (CRU), Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz (CiiEM), Egas Moniz Cooperativa de Ensino Superior, 2829-511 Almada, Portugal"},{"name":"Evidence-Based Hub, Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz (CiiEM), Egas Moniz Cooperativa de Ensino Superior, 2829-511 Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0167-4077","authenticated-orcid":false,"given":"Jos\u00e9 Jo\u00e3o","family":"Mendes","sequence":"additional","affiliation":[{"name":"Clinical Research Unit (CRU), Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz (CiiEM), Egas Moniz Cooperativa de Ensino Superior, 2829-511 Almada, Portugal"},{"name":"Evidence-Based Hub, Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz (CiiEM), Egas Moniz Cooperativa de Ensino Superior, 2829-511 Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2503-260X","authenticated-orcid":false,"given":"Vanessa","family":"Machado","sequence":"additional","affiliation":[{"name":"Clinical Research Unit (CRU), Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz (CiiEM), Egas Moniz Cooperativa de Ensino Superior, 2829-511 Almada, Portugal"},{"name":"Evidence-Based Hub, Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz (CiiEM), Egas Moniz Cooperativa de Ensino Superior, 2829-511 Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Sintra","family":"Delgado","sequence":"additional","affiliation":[{"name":"Clinical Research Unit (CRU), Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz (CiiEM), Egas Moniz Cooperativa de Ensino Superior, 2829-511 Almada, Portugal"},{"name":"Orthodontic Department, Egas Moniz Dental Clinic (EMDC), Egas Moniz Cooperativa de Ensino Superior, 2829-511 Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"103","DOI":"10.1093\/ejo\/cji083","article-title":"Development of a Questionnaire for Assessment of the Psychosocial Impact of Dental Aesthetics in Young Adults","volume":"28","author":"Klages","year":"2006","journal-title":"Eur.
