To integrate items from two widely used oral health-related quality of life (OHRQoL) questionnaires, the General Oral Health Assessment Index (GOHAI) and the Oral Impacts on Daily Performances (OIDP), as well as culturally-specific items of the Oral Health Impact Profile (OHIP) into a four-dimensional OHRQoL model consisting of Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact.
Subjects came from an ancillary study of the Dimensions of Oral Health-Related Quality of Life Project (N=267 patients, mean age±SD: 54.0±17.2years, 58% women.) Patients filled in the original 49 items of OHIP and 22 additional OHRQoL items in a cross-sectional study. These additional items consisted of 7 culturally specific OHIP items and 15 GOHAI or OIDP items with unique content not covered in OHIP-49. Before data collection, three experts hypothesized to which of the four OHRQoL dimensions these items belong. Hypotheses were tested in correlation analyses between the 22 items and the four dimension scores that were derived from OHIP-49.
Five of the 22 items did not provide sufficient information to which dimension they belong. In 16 of the remaining 17 items, the pattern of correlation coefficients fitted experts' a priori hypotheses. Acceptance of 16 of the 17 hypotheses was interpreted as evidence that additional (not in OHIP-49 contained) OHRQoL items can be assigned to Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact.
Items of three OHRQoL instruments can be integrated into a dimensional OHRQoL model consisting of Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact.
Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact can serve as a simple and clinically appealing set of oral health-related quality of life (OHRQoL) dimensions and therefore provide an opportunity for simpler, but psychometrically improved OHRQoL measurement in the future.
将两个广泛使用的口腔健康相关生活质量（OHRQoL）问卷——一般口腔健康评估指数（GOHAI）和口腔影响日常生活表现（OIDP）的项目，以及口腔健康影响概况（OHIP）的文化特异性项目整合到一个由口腔功能、口腔颌面疼痛、口腔颌面外观和心理社会影响组成的四维度 OHRQoL 模型中。
受试者来自 Dimensions of Oral Health-Related Quality of Life Project 的辅助研究（N=267 例患者，平均年龄±标准差：54.0±17.2 岁，58%为女性）。患者在横断面研究中填写了原始的 49 项 OHIP 和 22 项额外的 OHRQoL 项目。这些额外的项目包括 7 项具有文化特异性的 OHIP 项目和 15 项 GOHAI 或 OIDP 项目，这些项目的内容在 OHIP-49 中没有涵盖。在数据收集之前，三位专家假设这些项目属于四个 OHRQoL 维度中的哪一个。通过对 22 项与 OHIP-49 得出的四个维度评分之间的相关性分析来检验假设。
在 22 项中的 5 项中，没有提供足够的信息来确定它们属于哪个维度。在剩余的 17 项中的 16 项中，相关系数的模式符合专家的先验假设。接受 16 个假设被解释为额外（不在 OHIP-49 中包含）的 OHRQoL 项目可以被分配到口腔功能、口腔颌面疼痛、口腔颌面外观和心理社会影响的证据。
三个 OHRQoL 工具的项目可以整合到一个由口腔功能、口腔颌面疼痛、口腔颌面外观和心理社会影响组成的维度 OHRQoL 模型中。
口腔功能、口腔颌面疼痛、口腔颌面外观和心理社会影响可以作为一组简单而具有临床吸引力的口腔健康相关生活质量（OHRQoL）维度，从而为未来更简单但心理测量学上更改进的 OHRQoL 测量提供机会。
