The Oral Health-related Quality of Life (OHRQoL) is a multi-dimensional concept commonly used to examine the impact of health status on quality of life, and the Oral Health Impact Profile-14 (OHIP-14) questionnaire is a good self-assessment tool. This study was designed to investigate the factor structure of the OHIP-14 scale Chinese version, measurement invariance and latent mean differences across genders among college students.
The online survey was completed by 919 college students. This study used confirmatory factor analysis (CFA) to check the structural models of the OHIP-14 scale, The correlation of each item with the scale total score could test homogeneity, and Cronbach's alpha (Cronbach's α) could evaluate internal consistency. Multi-group CFA was used to explore whether the Chinese version of the OHIP-14 scale was used in male and female populations for measurement consistency. T-test compared scores between men and women. Regression analyses were used to evaluate the relationship between age, gender, education, subject, and the score on the OHIP-14 scale.
We found that the 7-factor structure had the best fit index in the sample. According to Cronbach's α, the overall score of OHIP was 0.958, and Cronbach's α for 7 factors was: functional limitation was 0.800, physical pain was 0.854, psychological discomfort was 0.902, physical disability was 0.850, psychological disability was 0.768, social disability was 0.862, social handicap was 0.819 and the test-retest reliability interval was 0.723. Multi-group confirmatory factor analysis supported residual measurement invariance across gender. T-test for scores showed that females scored higher significantly than men as did the overall score, in terms of physical pain (p<0.001), physical disability (p<0.001), and psychological disability (p<0.001).
This study found the OHIP-14 Chinese version to be a good tool for assessing the college students' OHRQoL in China, allowing people to conduct self-assessments.
口腔健康相关生活质量（OHRQoL）是一个多维概念，常用于评估健康状况对生活质量的影响，而口腔健康影响量表-14（OHIP-14）问卷是一种很好的自我评估工具。本研究旨在探讨 OHIP-14 量表中文版的结构、性别间的测量不变性和潜在均值差异。
919 名大学生在线完成了这项研究。本研究采用验证性因子分析（CFA）来检验 OHIP-14 量表的结构模型，每个项目与量表总分的相关性可以检验同质性，Cronbach's α（Cronbach's α）可以评估内部一致性。多组 CFA 用于探讨 OHIP-14 量表中文版在男女生群体中是否具有测量一致性。T 检验比较了男女之间的分数。回归分析用于评估年龄、性别、教育程度、学科与 OHIP-14 量表得分之间的关系。
我们发现，在样本中，7 因素结构具有最佳的拟合指数。根据 Cronbach's α，OHIP 的总分是 0.958，7 个因子的 Cronbach's α 分别为：功能受限为 0.800，身体疼痛为 0.854，心理不适为 0.902，身体残疾为 0.850，心理残疾为 0.768，社会障碍为 0.862，社会障碍为 0.819，重测信度间隔为 0.723。多组验证性因子分析支持性别间的残余测量不变性。分数的 T 检验表明，女性在身体疼痛（p<0.001）、身体残疾（p<0.001）和心理残疾（p<0.001）方面的得分显著高于男性，总分也是如此。
本研究发现，OHIP-14 中文版是评估中国大学生口腔健康相关生活质量的一种良好工具，允许人们进行自我评估。
