PurposeThe validated translations of the OHIP-EDENT exist in different languages; however,there is no reliable and validated Turkish translation. The present study wasconducted to evaluate the reliability and to validate the Oral Health Impact Profile inedentulous subjects translated to Turkish (OHIP-EDENT-T).Materials and MethodsThe study sample included 104 conventional complete denture wearers (58 womenand 46 men, mean age: 61.13 ± 9.43 years). The original English version of OHIPEDENTwas translated into Turkish using a forward-backward method and appliedto the subjects. The reliability of the OHIP-EDENT-T was evaluated using internalconsistency and the test–retest method. Validity was determined as construct andconvergent validity. The construct validity of OHIP-EDENT-T was assessed usingexploratory and confirmatory factor analysis.ResultsThe Cronbach’s alpha value for OHIP-EDENT-T was 0.890. The intraclass correlationcoefficient (ICC) was 0.749 for the OHIP-EDENT-T total score, and ICCs for thesubscales ranged from 0.630 (95% CI = 0.501-0.823) to 0.859 (95% CI = 0.531-0.897),indicating good to excellent agreement. The Kaiser-Meyer-Olkin value for samplingadequacy was 0.820 and results of Bartlett's sphericity test indicated statisticalsignificance (χ2=1139.767; df=171, p=0.001). This showed that factorial analysiscould be applied to the data set. The three-factor structure of the scale explained81.1% of the observed variance. The agreement of the three-factor solution wasfurther tested with confirmatory factor analysis, and the fit index was found to beacceptable (chi-square fit test=1.449, RMSEA=0.040, GFI=0.94, CFI=0.93).ConclusionWithin the limitations of this study, it can be concluded that OHIP-EDENT-T is a validand reliable instrument for evaluating the quality of life of edentulous patients.
