Development and psychometric properties of the Serbian version of the Orofacial Esthetic Scale

Abstract

ObjectiveThe aim of the study was to develop the Serbian language version of the Orofacial Esthetic Scale questionnaire (OES SERB) and to evaluate its psychometric properties.MethodsThe study included 226 subjects – 110 dental students and 116 patients (the validation sample). The students answered all the questions individually with the help of supervisors, whereas the prosthodontic patients were interviewed by the same trained dentist. The reliability and validity of the questionnaire were assessed.ResultsInternal consistency of the OES‐SERB was considered satisfactory (Cronbach's alpha 0.92, inter‐item correlation coefficient ranged between 0.735 and 0.898). The construct validity of the OES was proved using exploratory factor analysis, which confirmed the one‐ dimensional model of the OES‐SERB that assumed 66.549% of the variance. The Bartlett's test of sphericity was 1380.134 (df = 28, p < 0.001) and the Kaiser‐Meyer‐Olkin (KMO) test was 0.900. The total score was statistically significantly different between students and patients (p < 0.001), which confirmed the discriminant validity.ConclusionThe Serbian version of the OES, adapted to the cultural setting of the Republic of Serbia, has exhibited excellent psychometric properties and has been confirmed as a one‐dimensional tool for self‐assessment of the appearance of the orofacial region.Clinical SignificanceThe Serbian version of the OES has good psychometric properties and is a valuable instrument for self‐assessment of the appearance of the orofacial region.

Reliability and Validity of the Multidimensional Scale of Perceived Social Support Among Women and Adolescent Girls With Disabilities in Selected Sub-districts of Bangladesh

“…High values (around 1.0) denote that factor analysis has the benefit of interpreting this research data. If the value is below 0.50, the results of the factor analysis may not be very beneficial [ 19 , 20 ]. Bartlett's test of sphericity was utilized.…”

“…23 In the present study, the KMO measure of sampling adequacy exceeded the recommended threshold 32 and a one-factor structure was revealed by factor analysis, explaining 56.1% of the variance, consistent with the previous versions. 1,12,21,23,25 According to the analysis of factor loadings, all the items exhibited a coefficient surpassing the 0.50 threshold, indicating a robust association between each item and its respective factor.…”

“…A pleasant facial appearance plays an important role in social interactions and has been reported to increase an individual's self-confidence. 1 However, esthetic perception may vary across cultures, and it does not have definitive rules and is extremely subjective. 2,3 Improving dental esthetics is one of the main reasons for seeking dental treatment.…”

“…19 Cross-cultural adaptation of the OES involves translating and adapting the instrument into languages other than the source language. 1 The original survey has been translated and adapted into many different languages and is consistently acceptable in all cultures. 1,20,[21][22][23][24][25][26] The OES questionnaire has not been adapted to Turkish yet.…”

“…1 The original survey has been translated and adapted into many different languages and is consistently acceptable in all cultures. 1,20,[21][22][23][24][25][26] The OES questionnaire has not been adapted to Turkish yet. However, introducing it alongside the OHIP scale can significantly improve patients' satisfaction with dental treatment and prosthetic or restorative treatment outcomes.…”
