The Liverpool Oral Rehabilitation Questionnaire (LORQ) is a health-related quality of life instrument assessing the impact of oral rehabilitation on patients' health-related quality of life (HRQOL) following treatment for oral cancer. The small number of patients wearing prostheses in previous studies limited the validation of the denture/denture satisfaction part of the questionnaire.
The purpose of this study was to further validate the LORQ by obtaining HRQOL data from patients requiring replacement dentures.
The LORQv3, together with items assessing mood and anxiety, was administered with the Oral Health Impact Profile 14-item (OHIP-14) questionnaire to 104 consecutive patients, between the ages of 40 and 79, referred by their general dentists to the department of prosthodontics at the Liverpool University Dental Hospital for replacement of removable prostheses between November 2004 and June 2005. The Mann-Whitney and Kruskal-Wallis tests compared scores between patient groups. Internal consistency was measured by Cronbach's alpha. Spearman's correlation investigated associations between items on the LORQv3 and items from the OHIP-14. Test-retest was measured by the kappa coefficient, weighted by applying standard weights according to the number of categories in error.
Patients wearing complete dentures in 1 or both arches generally scored worse for oral function and mandibular denture problems/satisfaction than patients wearing removable partial dentures. Thirty-three percent of patients were somewhat or extremely depressed, 25% were anxious or very anxious, and 15% were both depressed and anxious.
The denture section of the LORQv3 identified expected differences among various patient subgroups in this cohort confirmed by similar findings for the OHIP-14 and the literature. Thus, this part of the LORQv3 referring to dentures and patient satisfaction demonstrated good construct and criterion validity.
利物浦口腔修复问卷（LORQ）是一种与健康相关的生活质量工具，用于评估口腔修复对口腔癌患者治疗后与健康相关的生活质量（HRQOL）的影响。以往研究中佩戴假牙的患者数量较少，限制了问卷中假牙/假牙满意度部分的验证。
本研究的目的是通过从需要更换假牙的患者中获取HRQOL数据，进一步验证LORQ。
2004年11月至2005年6月期间，104名年龄在40至79岁之间的连续患者，由他们的普通牙医转介至利物浦大学牙科医院口腔修复科进行可摘义齿更换，LORQv3与评估情绪和焦虑的项目一起，与口腔健康影响概况14项问卷（OHIP-14）一同发放。采用Mann-Whitney和Kruskal-Wallis检验比较患者组之间的得分；通过Cronbach's alpha测量内部一致性；Spearman相关性研究LORQv3项目与OHIP-14项目之间的关联；通过kappa系数测量重测信度，并根据错误类别数量应用标准权重进行加权。
在一个或两个牙弓上佩戴全口义齿的患者，其口腔功能和下颌义齿问题/满意度得分通常比佩戴可摘局部义齿的患者更差。33%的患者有一定程度或极度抑郁，25%的患者焦虑或非常焦虑，15%的患者既抑郁又焦虑。
LORQv3的假牙部分在该队列的不同患者亚组中识别出了预期差异，OHIP-14和文献的类似发现证实了这一点。因此，LORQv3中这部分关于假牙和患者满意度的内容显示出良好的结构效度和标准效度。
