This study aimed to assess the level of agreement between two commonly used oral health-related quality of life (OHRQoL) measures, the short form of the Oral Health Impact Profile (OHIP14) and the Oral Impacts on Daily Performances (OIDP).
A sample of 1,675 15- to 16-year-old students attending all schools in Bauru (Sao Paulo, Brazil) was selected. The impact of oral conditions on quality of life in the last 6 months was reported using both OHIP14 and OIDP. To allow for comparison with the 100 percent OIDP score, OHIP14 scores were converted to percentages. Then, agreement between the two OHRQoL measures was analyzed using the Bland and Altman method.
The mean difference between OHIP14 and OIDP was 6.48 percent [confidence interval 95% (6.08; 6.89)], with higher scores reported for OHIP14 than for OIDP. Besides, 95 percent of the differences between the two OHRQoL measures were between -10.59 and 23.56 percent. Finally, differences between OHIP14 and OIDP increased significantly as the magnitude of their average increased (P < 0.001).
There was a moderate level of agreement between OHIP14 and OIDP, which may be partly due to the fact that both OHRQoL measures assess different levels of oral impacts on quality of life in addition to having different scoring systems.
本研究旨在评估两种常用的口腔健康相关生活质量（OHRQoL）测量工具，即口腔健康影响简表（OHIP14）和口腔影响日常活动（OIDP）之间的一致性水平。
选择了 1675 名 15 至 16 岁的学生，他们就读于巴西包鲁市的所有学校。使用 OHIP14 和 OIDP 报告过去 6 个月口腔状况对生活质量的影响。为了与 100%的 OIDP 得分进行比较，将 OHIP14 得分转换为百分比。然后，使用 Bland 和 Altman 方法分析两种 OHRQoL 测量工具之间的一致性。
OHIP14 和 OIDP 之间的平均差异为 6.48%（置信区间 95%（6.08；6.89%）），OHIP14 的得分高于 OIDP。此外，两种 OHRQoL 测量工具之间的 95%差异在-10.59%和 23.56%之间。最后，当两种 OHRQoL 测量工具的平均得分增加时，它们之间的差异显著增加（P<0.001）。
OHIP14 和 OIDP 之间存在中等程度的一致性，这可能部分归因于这两种 OHRQoL 测量工具评估了不同程度的口腔对生活质量的影响，此外它们还有不同的评分系统。
