title: The Mandarin Chinese shortened version of Oral Health Impact Profile for partially edentate patients with implant-supported prostheses.
abstract: 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.
