Psychometric properties of the Albanian version of the Orofacial Esthetic Scale: OES-ALB

Abstract

The aim was to adapt the Orofacial Esthetic Scale (OES) and to test psychometric properties of the Albanian language version in the cultural environment of the Republic of Kosovo.MethodsThe OES questionnaire was translated from the original English version according to the accepted techniques. The reliability (internal consistency), and validity (construct, convergent and discriminative) were tested in 169 subjects, test-retest in 61 dental students (DS), and responsiveness in 51 prosthodontic patients with treatment needs (PPTN).ResultsThe corrected item correlation coefficients of OES-ALB ranged from 0.686 to 0.909. The inter-item correlation coefficient ranged between 0.572 and 0.919. The Cronbach’s alpha was 0.961 and IIC 0.758. Test- retest was confirmed by good ICCs and by no significant differences of the OES scores through the period of 14 days without any orofacial changes (p > 0.05). Construct validity was proved by the presence of one-factor composition that assumed 79.079 % of the variance. Convergent validity showed significant correlation between one general question about satisfaction with orofacial esthetics and the OES summary score, as well as between the sum of the 3 OHIP-ALB49 questions related to orofacial aesthetics and the OES summary score. Discriminative validity was confirmed with statistically significant differences between DS, prosthodontic patients without treatment need and PPTN (p < 0.01). Responsiveness was confirmed by a significant increase of OES scores after PPTN patients received new fixed partial or removable dentures (P < 0.001).ConclusionThe results proved excellent psychometric properties of the OES-ALB questionnaire in the Republic of Kosovo.

Development and psychometric properties of the Portuguese version of the Orofacial Esthetic Scale: OES-Pt

“…The OES has one total score (Larsson et al, 2010). The instrument has already been translated and adapted for different countries (Alhajj et al, 2017;Bimbashi et al, 2015;N'Guyen-Van, Moreau & Braud, 2019;Persic et al, 2011;Reissmann et al, 2015;Simancas-Pallares et al, 2018;Wetselaar et al, 2015;Zhao & He, 2013) and applied to different contexts, such as the general population (John et al, 2012), specific dental patients such as denture wearers (Larsson et al, 2010), and dental patients in general (Reissmann et al, 2019). In addition, some studies have evaluated the psychometric properties of OES, attesting to its validity and reliability for the Swedish general population (John et al, 2012) and for the population of North American dental patients (Reissmann et al, 2019).…”

Impact of administration mode on Oro‐facial Appearance assessment using the Oro‐facial Esthetic Scale

“…However, this should not be a limitation. Other studies already proved convergent validity with external ratings of Oro‐facial Appearance, known‐groups validity, responsiveness and test‐retest reliability of the OES . We see no reason why this should be related to the method of administration.…”

“…Therefore, the Oro‐facial Esthetic Scale (OES), an 8‐item instrument, was developed to overcome this drawback and to comprehensively assess Oro‐facial Appearance from the patient perspective . The OES is unidimensional, exhibited good psychometric properties and is available in several languages . Furthermore, norm values were provided for the general population …”

Measuring Patient’s Orofacial Estheticsin in Prosthodontics: A Scoping Review of a Current Instrument

“…The OES instead evaluates the overall satisfaction of the patient with his/her esthetic appearance. As the most common instrument used in research, the OES has good psychometric properties and has been adapted cross-culturally to several languages such as; Croatia,Chinese,Albanian,Dutch,Germany,Arabic,and Spanish [25,29,[32][33][34]37,40,41]. Although the instrument developed by Tortopidis et al showed good reliability, there has been no report of its use in other published studies.…”
