Summary The aim of this study was to investigate the psychometric properties of the O ro‐facial E sthetic S cale among C hinese‐speaking patients. The original Oro‐facial Esthetic Scale was cross‐culturally adapted in accordance with the international standards to develop a Chinese version ( OES ‐ C ). Unlike the original O ro‐facial E sthetic S cale, the version employed in this study used a 5‐point Likert scale with items rated from unsatisfactory to most satisfactory. Psychometric evaluation included the reliability and validity of the OES ‐ C . The reliability of the OES ‐ C was determined through internal consistency and test–retest methods. The validity of OES ‐ C was analysed by content validity, discriminative validity, construct validity and convergent validity. The corrected item‐total correlation coefficients of the OES ‐ C ranged from 0·859 to 0·910. The inter‐item correlation coefficients between each two of the eight items of the OES ‐ C ranged from 0·766 to 0·922. The values of ICC ranged from 0·79 (95% CI = 0·54–0·98) to 0·93 (95% CI = 0·87–0·99), indicating an excellent agreement. Construct validity was proved by the presence of one‐factor structure that accounted for 83·507% of the variance and fitted well into the model. Convergent validity was confirmed by the association between OES ‐ C scores and self‐reported oral aesthetics and three questions from the Oral Health Impact Profile related to aesthetics (correlation coefficients ranged from −0·830 to −0·702, P < 0·001). OES ‐ C scores discriminated aesthetically impaired patients from healthy controls. This study provides preliminary evidence concerning the reliability and validity of the OES ‐ C . The results show that the OES ‐ C may be a useful tool for assessment of oro‐facial esthetics in C hina.
