虽然口腔健康影响概况(OHIP)测量的口腔健康相关生活质量(OHRQOL)被认为是多维的,但这些维度的性质尚不清楚。这份报告的目的是利用OHRQOL(DOQ)项目的维度来探索OHIP的维度,该项目是一项针对普通人群受试者和口腔修复患者的国际研究。使用该项目的学习样本(N=5,173),我们对5,146名数据足够完整的受试者的46个OHIP项目进行了探索性因素分析。多谐相关矩阵的第一特征值(27.0)比第二特征值(2.6)大十倍以上,表明存在一个占主导地位的高阶通因。霍恩的平行分析的后续分析揭示了一个可行的二阶四因素解决方案。倾斜旋转这个溶液发现了四个高度相关的因素,我们将其命名为口腔功能、口腔面部疼痛、口腔面部外观和心理社会影响。这四个维度和较强的总因子是OHIP因素结构的两个可行假设。
Although oral health-related quality of life (OHRQoL) as measured by the Oral Health Impact Profile (OHIP) is thought to be multidimensional, the nature of these dimensions is not known. The aim of this report was to explore the dimensionality of the OHIP using the Dimensions of OHRQoL (DOQ) Project, an international study of general population subjects and prosthodontics patients. Using the project's Learning Sample (N=5,173), we conducted an exploratory factor analysis on the 46 OHIP items not specifically referring to dentures for 5,146 subjects with sufficiently complete data. The first eigenvalue (27.0) of the polychoric correlation matrix was more than ten times larger than the second eigenvalue (2.6), suggesting the presence of a dominant, higher-order general factor. Follow-up analyses with Horn's parallel analysis revealed a viable second-order, four-factor solution. An oblique rotation of this solution revealed four highly correlated factors that we named Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact. These four dimensions and the strong general factor are two viable hypotheses for the factor structure of the OHIP.
