Summary This study was to validate a mandarin Chinese version of Oral Health Impact Profile (OHIP‐49) in China and to develop a shortened version of OHIP appropriate for use in partially dentate patients with implant‐supported prostheses. The original 49 items of OHIP were translated into mandarin Chinese using a forward–backward method and administered to 580 subjects selected by stratified random sampling. Self‐perceived oral health status and treatment need were also collected. Reliability and validity of the Chinese version of OHIP (OHIP‐C49) were validated. A shortened version (OHIP‐I) was derived from the OHIP‐C49 by exploratory factor analysis (EFA) as well as expert‐based approach in partially dentate patients ( n = 102) with implant‐supported prostheses. For validation of the new modified shortened version, another independent sample of 97 partially dentate patients completed OHIP‐I and their self‐perceived oral health status at baseline and at least 3 months after dental implant rehabilitation. Five hundred and thirty‐seven effectual questionnaires were reclaimed from the 580 subjects interviewed. Cronbach’s alpha ranged from 0·78 to 0·96 and test–retest correlation coefficients ranged from 0·84 to 0·97 for subscale and summary scores. Construct validity was demonstrated by priori hypothesised associations between the OHIP‐C49 scores and self‐perceived oral health ( P < 0·001). The reliability and validity of OHIP‐I were similar to which of the OHIP‐C49, and the responsiveness appeared able to measure the effect of dental implant therapy effectively. The mandarin version of OHIP‐49 showed sufficient psychometric properties for Chinese. The modified shortened version (OHIP‐I) may be appropriate for the evaluation of implant therapy outcomes in partially dentate Chinese patients.
