Validity of the Psychosocial Impact of Dental Aesthetics Questionnaire for use on Brazilian adolescents

Abstract

Introduction:The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) is a multi-item psychometric instrument used to assess patients' perspective of the impact specifically related to Orthodontics. The cross-culturally adapted Brazilian version of the PIDAQ has demonstrated good reliability, validity and acceptability.Objective: The aim of the present study was to test the validity and reliability of the Brazilian version of the PIDAQ for use among adolescents aged between 11 and 14 years old.Methods: Having established the possibility of maintaining the operational characteristics of the Brazilian version of PIDAQ for the target age group, 194 individuals in the city of Belo Horizonte, Brazil, completed the questionnaire. The subjects were examined for the presence/absence of malocclusion based on the criteria of the Dental Aesthetic Index (DAI) to test discriminant validity. Internal consistency was measured by means of Cronbach's alpha coefficient which ranged from 0.59 to 0.86 for the subscales. Test-retest reliability was assessed by means of intraclass correlation coefficient which ranged from 0.54 to 0.89 for aesthetic concern and psychological impact.Results: Discriminant validity revealed that subjects without malocclusion had different PIDAQ scores in comparison to those with malocclusion.Conclusion: These findings suggest that the Brazilian version of PIDAQ for adolescents has satisfactory psychometric properties and is applicable to this age group in Brazil.

Validity and Reliability of the Arabic Version of the Psychosocial Impact of Dental Aesthetics Questionnaire for Yemeni Adolescents

“…Similar to our PIDAQ(A), two other related studies have found that the questionnaire comprised three factors [43,44], while one study yielded only two factors [17], and another study yielded five factors [47]. In addition, there are a small number of adaptations which did not incorporate factor analysis into their validation [48][49][50].…”

Translation and validation of the Swedish version of the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) for adolescents

“…Two translations have found that the instrument has three dimensions [17,23], and one translation revealed five dimensions [15]. Finally, there are a few translations which have not included factor analysis in their validation [13,16,25]. It can be concluded that PIDAQ seems to display different factor structures in different translations and populations.…”

“…PIDAQ has been translated into several languages and validated for use on adult populations [13][14][15][16][17][18][19][20][21]. The original adult version of PIDAQ has also been translated and validated on children and adolescents [22][23][24][25][26].…”

The influence of oral conditions on quality of life of adolescents: an integrative review

“…Este questionário desenvolvido por Slade e Spence (1994) foi posteriormente atualizado, em 1997, e uma versão simplificada foi criada, o OHIP-14 que tem sido comumente empregado em estudos recentes, por ter uma sólida base conceitual, boas propriedades psicométricas conhecida e fácil administração 29 . Apenas em um estudo, verificou-se a aplicação de um instrumento com abordagem especifica para uma condição de saúde bucal (Ortodontia) objetivando avaliar o impacto psicossocial nestes adolescentes 19 .…”
