Abstract

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.

Methods

The 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).

Results

The 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).

Conclusion

The results proved excellent psychometric properties of the OES-ALB questionnaire in the Republic of Kosovo.
