To analyse the validity of the Brazilian versions of OHIP-EDENT and GOHAI as assessment tools of edentulous subjects' OHRQoL.
Inventories for measuring oral health-related quality of life (OHRQoL) are important in clinical studies regarding oral rehabilitation. However, there is a need for comprehensive validation after translation into different cultural settings.
The sample comprised of 100 complete denture wearers (29 men, 71 women, mean age of 65.2 ± 9.9 years). The associations between each OHRQoL inventory and other variables served as measurements of construct validity. Data analysis comprised the Spearman correlation test as well as multiple regression using the OHRQoL inventories as dependent variables and the other scales as determinants.
Both OHRQoL inventories showed good correlation with denture satisfaction, whereas lower correlation coefficients were found among the inventories and the HAD subscales. Denture satisfaction alone explained 48% and 39% of the variance found for the OHIP-EDENT and GOHAI, respectively, as assessed by multiple regression. A smaller effect was found for OHIP-EDENT.
Both OHIP-EDENT and GOHAI showed good construct validity for measurement of OHRQoL of edentulous subjects.
分析巴西版 OHIP-EDENT 和 GOHAI 在评估无牙颌患者口腔健康相关生活质量（OHRQoL）方面的有效性。
用于测量口腔健康相关生活质量（OHRQoL）的量表在口腔修复的临床研究中很重要。然而，在翻译成不同的文化背景后，需要进行全面的验证。
样本包括 100 名全口义齿佩戴者（29 名男性，71 名女性，平均年龄 65.2±9.9 岁）。每个 OHRQoL 量表与其他变量之间的关联作为结构有效性的测量。数据分析包括 Spearman 相关检验以及使用 OHRQoL 量表作为因变量和其他量表作为决定因素的多元回归。
两种 OHRQoL 量表与义齿满意度均呈良好相关性，而量表与 HAD 子量表之间的相关性较低。多元回归分析显示，义齿满意度分别解释了 OHIP-EDENT 和 GOHAI 方差的 48%和 39%。OHIP-EDENT 的影响较小。
OHIP-EDENT 和 GOHAI 均显示出良好的结构有效性，可用于评估无牙颌患者的 OHRQoL。
