QUALITY OF LIFE OUTCOMES FOR ORAL HEALTH CARE

本项目的目标是开发和验证一个模块化的 测量口腔保健的生活质量结果的工具。 口腔健康调查显示， 在那些患有癌症的人中 未经治疗的口腔疾病和牙齿护理不足。但最近的 研究结果表明，用于测量口腔健康相关的工具， 生活质量（OHRQOL）在这些调查中不适合用于 结果研究，部分原因是它们似乎捕捉到了 OHRQOL对短期变化反应迟钝。 该项目旨在 综合五个现有OHRQOL工具的核心问题， 然后开发和评估核心的信度和效度 评估口腔保健效果的工具。 其他目标 将：检查OHRQOL和一般健康相关 生活质量;比较心理测量和基于效用的措施， OHRQOL;并确定从 为文书的核心内容增加补充模块， 问题. 次要，分析代表性人群的数据 在口腔健康调查中使用OHRQOL工具的人， 着手综合一系列问题， 牙科护理变量和验证性定性研究将 用于评估这些问题的适当性。比较评级 将使用程序获得项目的患者偏好权重 在核心调查表和原型补充模块中。测试- 重测信度和内部一致性信度将在200个 社区成员。将在四个准实验中评估有效性 接受口腔保健的患者的子研究：51 颞下颌关节紊乱病患者，508例患者接受一般 牙科护理，126名牙科植入患者和56名牙科患者， 艾滋病毒感染。其中两项子研究将同时评估 一般生活质量指标（SF-36）的变化和 健康状况的效用测量，两个子研究将 评估OHRQOL补充模块的性能。

The objective of this project is to develop and validate a modular instrument measuring quality of life outcomes from oral health care. The need for such an instrument has emerged from oral health surveys that have demonstrated poorer quality of life among people with untreated oral disease and inadequate dental care. However, recent findings suggest that instruments used to measure oral health related quality of life (OHRQOL) in such surveys are unsuited for use in outcomes research, in part because they appear to capture aspects of OHRQOL that are unresponsive to short term change. This project aims to synthesize core questions from five existing OHRQOL instruments, then develop and evaluate the reliability and validity of the core instrument for assessing effects of oral health care. Additional aims will: examine relationships between OHRQOL and generic health related quality of life; compare psychometric and utility-based measures of OHRQOL; and determine what additional explanatory power is gained from the addition of supplementary modules to the instruments core set of questions. Secondary, analysis of data from representative populations that have used OHRQOL instruments in oral health surveys will be undertaken to synthesize a set of questions that are associated with dental care variables, and confirmatory qualitative research will be used to assess the adequacy of those questions. Comparative rating procedures will be used to obtain patient-preference weights for items in the core questionnaire and prototype supplementary modules. Test- retest and internal consistency reliability will be evaluated among 200 community members. Validity will be assessed in four quasi-experimental sub-studies of patients receiving oral health care: 51 temporomandibular disorder patients, 508 patients receiving general dental care, 126 dental implant patients, and 56 dental patients with HIV infection. Two of those sub-studies will concurrently evaluate changes in a generic quality of life measure (SF-36) and changes in utility measurements of health status, and two sub-studies will evaluate the performance of supplementary modules of OHRQOL.
