口腔健康影响程度量表的验证研究

Validation of a Chinese version of the oral health impact profile-14

目的通过对口腔健康影响程度量表（OHIP-14中文版）的验证研究及其性质的考评，对该量表的信度、效度作出评价，探讨其在中国人群中进一步应用的可行性。方法按照国际生存质量评价（IQOLA）项目的标准程序，对OHIP-14进行翻译、回译、文化调适和改造，建立口腔健康影响程度量表。使用该量表和《口腔健康自我评价表》，对广东省部分地区年龄在18～65岁之间的居民应用多阶段简单随机抽样法，共抽取592个个体进行口腔健康相关生存质量调查，对调查结果进行统计学分析，考评量表的信度和效度。结果共有592位个体接受调查。回收有效问卷550份，其中数据缺失问卷38份。口腔健康影响程度量表内部一致性Cronbach’s α系数为0．93，条目与量表间的相关系数在0．53～0．71之间。因子分析提取的4个维度显示，口腔健康影响程度量表存在预想的连带关系和逻辑关系。量表得分与自我评价的口腔健康、自我感觉的治疗需要间呈显著正相关，相关系数分别为0．54、0．49（P〈0．0001）。结论口腔健康影响程度量表具有良好的信度、效度，其良好的心理测量学性质，为该量表在中国人群中的进一步推广应用提供了理论依据。

Objective To translate the original English version of oral health impact profile （OHIP） -14 into Chinese version and to test the psychometric properties of the Chinese version for use among the Chinese adults. Methods The original English version of OHIP-14 was translated into Chinese, and pre-tested and cross-cultural adapted. Subsequently the Chinese version with a general questionnaire was administered to adults aged 18 -65 years by a trained interviewer. Reliability of the translated scale was assessed in terms of internal consistency using Cronbach＇s alpha and corrected item-total correlation. Construct validity was evaluated by factor analysis and criterion-related validity was evaluated by examining the associations between perceived oral health status, perceived need for dental care and OHIP-14 scores. Formal psychometric properties were tested according to the standard procedure of the international quality of life assessment （IQOLA） project. Results A total of 592 adults were surveyed. There were 550 valid questionnaires involving 38 ones with missing data. Cronbach＇ s alpha of the translated scale was 0. 93, corrected item-total correlation ranged from 0. 53 to 0. 71. The 14 items were divided into four domains. There was certain logical relation between the items in the same domains. There was highly significant association between perceived oral health status, perceived need for dental care and OHIP-14 scores. Conclusions The translated Chinese version of OHIP-14 demonstrated good reliability and validity. Its good psychometric properties provide the theoretical evidence for further use in Chinese population. It is available for use by researchers in oral health related quality of life studies in Chinese adults.
