Abstract

Aim: To translate into the Albanian language the 14-item Oral Health Impact Profile (OHIP) Questionnaire (short version) and to measure its psychometric properties. Methods: The OHIP14 questionnaire was translated from the original English version, into Albanian (OHIP – LB14), according to the accepted techniques of forward-backward translation. The psychometric properties of the OHIP- ALB14 were then tested. The convergent validity was tested in 450 subjects [general population (n=125), removable prosthodontic patients (n=275) and students (n=50)]. The discriminative validity was tested between edentulous patients wearing dentures (CDWs) (n=233) and edentulous patients without any dentures (n=42). The test-retest reliability was tested on 50 dental students who completed the questionnaire twice within at least 2-weeks interval, without any oral problems in the meantime. The internal consistency was tested in 450 subjects by calculating Cronbach alfa coefficient. The responsiveness was tested in a group of 42 patients with a treatment demand who completed the OHIP- ALB14 before treatment and one month after receiving their new dentures. Results: The convergent validity was confirmed by significant association between the OHIP summary scores and the self-reported oral health (p<0.01). The discriminative validity was confirmed by significantly higher OHIP scores in edentulous subjects without any dentures compared to those wearing complete dentures (p<0.01), as predicted. The test-retest reliability was confirmed by high interclass correlation coefficients and no significant differences between the two administrations of the OHIP- ALB14 questionnaire (p>0.05) to dental students, who had no orofacial problems during the observed period. The internal consistency was confirmed by a high Cronbach’s alpha coefficient in general population (0.86), in prosthodontic patients (0.81), as well as in the student group (0.89). The responsiveness was confirmed by a
statistically significant difference between the mean OHIP baseline score and the mean OHIP follow-up score (p<0.001) in patients who received new complete dentures, and by the high effect size (1.72 for the OHIP Summary Score). Conclusion: The psychometric properties of the OHIPALB14 proved that the instrument is appropriate for the assessment of the Oral Health Related Quality of Life in Kosovo and the Albanian language speaking countries.
