The primary objective of the present study was to investigate the dimensional structure of the OHIP-14 in a sample of elderly Norwegians. A secondary objective was to describe associations between the exposed OHIP-14 dimensions and additional self-report oral health-related variables to assess the dimensions' criterion validity.
A survey questionnaire including the OHIP-14 and additional self-report oral health-related measures was completed by 325 home-dwelling Norwegians aged 70+. Exploratory factor analysis was used to investigate the dimensional structure of the OHIP-14 in this sample. Bivariate correlations were used to describe associations between the exposed OHIP-14 dimensions and additional self-report oral health-related variables.
Three dimensions named and were revealed. Convergent and discriminant validity of these dimensions were largely supported, and internal consistency reliability for each dimension was good. Statistically significant associations were found between the exposed dimensions and additional self-report oral health-related variables, supporting the dimensions' criterion validity.
A three-dimensional structure of the OHIP-14 was exposed and validated in the present study sample. Since different aspects of oral health-related quality of life (OHRQoL) may be perceived and weighted differently in various populations, suggestions for future research include more profound investigations of the construct validity of the OHIP-14 and similar instruments assessing OHRQoL. Such research should include an exploration of various dimensions and the weights given to them through qualitative research in the target population(s).
本研究的主要目的是在一组挪威老年人样本中调查OHIP-14的维度结构。次要目的是描述OHIP-14各维度与其他自我报告的口腔健康相关变量之间的关联，以评估这些维度的效标效度。
325名70岁及以上的挪威居家老人完成了一份包含OHIP-14和其他自我报告的口腔健康相关测量指标的调查问卷。采用探索性因素分析来研究该样本中OHIP-14的维度结构。使用双变量相关性来描述OHIP-14各维度与其他自我报告的口腔健康相关变量之间的关联。
揭示了三个维度，分别命名为[未提及具体维度名称]。这些维度的收敛效度和区分效度在很大程度上得到了支持，且每个维度的内部一致性信度良好。在各维度与其他自我报告的口腔健康相关变量之间发现了具有统计学意义的关联，支持了这些维度的效标效度。
在本研究样本中揭示并验证了OHIP-14的三维结构。由于口腔健康相关生活质量（OHRQoL）的不同方面在不同人群中可能会被不同地感知和权衡，未来研究的建议包括对OHIP-14和评估OHRQoL的类似工具的结构效度进行更深入的研究。此类研究应包括通过对目标人群进行定性研究来探索各个维度及其赋予的权重。
