The Slovenian version of the Oral Health Impact Profile questionnaire: translation and psychometric properties

Purpose The aims of the study was to develop and to test the psychometric properties of the Slovenian version (OHIP-SVN) in the new cultural context. Materials and Methods The original version was translated into the Slovenian language by a forward-backward translation method. The psychometric properties of the OHIP-SVN were tested. Construct validity was tested on 430 subjects, test-retest reliability on 60 subjects, internal consistency on 460 subjects, and responsiveness was tested on 30 patients with a treatment demand (toothache). Results The significant association between the OHIP summary scores and the self-reported oral health (P < .01) confirmed the construct validity. The test-retest reliability showed high intraclass correlation coefficients and no significant differences between the two administrations (P > .05). The internal consistency showed high Cronbach's alpha (0.97). The responsiveness was confirmed by the statistically significant difference between the mean OHIP score at baseline and follow-up (P < .01) and by the considerable effect size in the Slovenian patients with a treatment demand (0.515). The results of the psychometric evaluation of the OHIP-SVN were similar to other validated translations reported up to date. Conclusion The OHIP-SVN, together with the presented psychometric properties in a typical patient population prove that this instrument is suitable for the assessment of the Oral Health Related Quality of Life in Slovenia.
