Abstract
(1) Objectives: This paper aimed to cross-culturally adapt the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) into an Arabic language version (PIDAQ(A)) for measuring the oral health related quality of life related to dental aesthetics among 12–17-year-old Yemeni adolescents. (2) Material and methods: The study comprised three parts, which were linguistic validation and qualitative interview, comprehensibility assessment, and psychometric validations. Psychometric properties were examined for validity (exploratory factor analysis (EFA), partial confirmatory factor analysis (PCFA), construct, criterion, and discriminant validity) and reliability (internal consistency and reproducibility). (3) Results: The PIDAQ(A) contained a new item. EFA extracted three factors (item factor loading 0.375 to 0.918) comprising dental self-confidence, aesthetic concern, and psychosocial impact subscales. PCFA showed good fit statistics (comparative fit index (CFI) = 0.928, root-mean-square error of approximation (RMSEA) = 0.071). In addition, invariance across age groups was tested. Cronbach’s α values ranged from 0.90 to 0.93 (intraclass correlations = 0.89–0.96). A criterion validity test showed that the PIDAQ(A) had a significant association with oral impacts on daily performance scores. A construct validity test showed significant associations between PIDAQ(A) subscales and self-perceived dental appearance and self-perceived need for orthodontic braces (p < 0.05). Discriminant validity presented significant differences in the mean PIDAQ(A) scores between subjects having severe malocclusion and those with slight malocclusion. No floor or ceiling effects were detected.
Highlights
The face and content validity of the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ)(A) was confirmed by the experts who concluded that it achieved item and conceptual equivalences with the source version
Any words which upon translation reflected various concepts in the Arabic language and Yemeni culture were replaced with suitable words having similar concepts to the source items
The current study demonstrated that the English PIDAQ has been successfully crossculturally adapted into the Arabic language for the Yemeni population with some modifications
Summary
Malocclusion is a condition of poor dental arrangement and has been shown to correlate with higher levels of dissatisfaction with dental appearance [1,2]. Recent years have seen increased interest in research on patients’ experiences concerning the impact of their dental aesthetics on their oral health related quality of life (OHRQoL) [3,4]. Indices of OHRQoL that measure the subjective perceptions of patients are considered an important complement to normative clinical indicators [5]. Normative assessment of orthodontic treatment need using clinical indices has attempted to analyze the dental health and aesthetic aspects of malocclusion [6]. One of the common indices used in this respect is the Index of Orthodontic Treatment Need (IOTN)
