The Oral Health Values Scale is a multidimensional instrument that identifies and measures a person's values related to oral health. This scale has been validated in American respondents. This study aims to evaluate the adaptability and validity of the Oral Health Values Scale in the Hindi language (H-OHVS). A total of 240 adults participated in the study that was carried out from July to November 2022. An offline one-to-one survey was carried out to collect data by an investigator blinded to the study protocol. The translation and testing of the OHVS were carried out based on the cross-cultural adaptation guidelines of the American Academy of Orthopedic Surgeons (AAOS) Evidence-Based Medicine Committee. The content validity was assessed by an expert panel. Construct validity was analyzed through Exploratory Factor Analysis (EFA), utilizing principal component analysis with varimax rotation. The internal consistency of the Hindi version of OHVS was evaluated using Cronbach's alpha.  The results showed that H-OHVS had an Item-level Construct Validity Index (I-CVI) ranging from 0.82 to 1.00. Two components, compliance and hesitance, were formed on H-OHVS accounting for 63.91% of the cumulative variance. The resulting model fit indices on confirmatory factor analysis presented an adequate fit to the data. The overall Cronbach's alpha coefficient for H-OHVS (α = 0.868) presents excellent internal consistency. The study findings provide a certain degree of evidence in favor of this scale and establish the Oral Health Values Scale (OHVS) as a psychometrically sound measure.
