VALIDATION OF SELF ADMINISTERED QUALITY OF WELL BEING SCALE IN ARTHRITIS

幸福感质量量表是面试者管理的 衡量与健康相关的生活质量。这一措施已被使用 在各种各样的成果和公共政策研究中。一位少校 该措施的特点是可用于成本效用分析。 至少有三个人批评QWB的结果 关节炎方面的研究。首先，QWB必须由一个 采访者。其次，QWB没有得到具体的验证 适用于关节炎患者。第三，偏好权重系统是 依据的是普通人群而不是关节炎患者。这个 QWB最近被重新开发为一个自我管理的 问卷(QWB-SA)。这项研究的目的是验证 QWB-SA适用于关节炎和肌肉骨骼疾病患者。 这项研究有四个具体目标。第一个目标是证明 QWB-SA治疗关节炎患者的可行性 肌肉骨骼疾病。QWB-SA将与 使用AIMS-2和SF-36到1500名患者。分析将 考虑完成回复的比率、回复的差异，以及 缺少信息。第二个具体目标是开发一个 关节炎特异性QWB-SA。这将通过分析 收集的与具体目标有关的数据1.比较 关节炎和非患者，使用项目分析，将识别 将关节炎患者与其他患者分开的措施的组成部分 患有其他疾病的患者。第三个目标是比较 关节炎患者和非患者的偏好。这将是 通过获得案例描述和分析的评级来实现 患者对结果的偏好是否与非患者不同 病人。第四个具体目标将是确定是否 急性期和非急性期患者对结局的偏好不同 剧烈疼痛状态。这项研究将使用100个类风湿性关节炎 病人。有一半的患者会在急性发作时进入研究。 而其他人会在他们不是急性子的时候进入。两者都有 小组将被前瞻性地跟踪。该研究的成果 将是公共政策研究的一个更好的结果衡量标准 与关节炎有关。

The Quality of Well-being Scale is an interviewer-administrated measure of health-related quality of life. The measure has been used in a wide variety of outcome and public policy studies. A major feature of the measure is that it can be used for cost-utility analysis. There have been at least three criticism of the QWB for outcome studies in arthritis. First, the QWB must be administered by an interviewer. Second, the QWB has not been validated specifically for patients with arthritis. Third, the preference weighting system is based on the general population rather than arthritis patients. The QWB has recently been redeveloped as a self-administered questionnaire (QWB-SA). The purpose of the study is to validate the QWB-SA for patients with arthritis and musculoskeletal disorders. This study has four Specific Aims. The first Aim is to demonstrate the feasibility of the QWB-SA for patients with arthritis and musculoskeletal disorders. The QWB-SA will be administered along with the AIMS-2 and the SF-36 to 1,500 patients. Analysis will consider rates of completed responses, difference in response, and missing information. The second Specific Aim is to develop an arthritis-specific QWB-SA. This will be accomplished by analyzing data collected in relation to Specific Aim 1. Comparisons between arthritis and non patients, using item analysis, will identify components of the measure that separate arthritis patients from patients with other illnesses. The third Aim is to compare preferences from arthritis patients and non patients. This will be accomplished by obtaining ratings for case descriptions and analyzing whether patients have different preference for outcome that non patients. The fourth Specific Aim will be to determine whether patients have different preference for outcome when in acute or non acute pain states. This study will use 100 Rheumatoid Arthritis patients. Half the patients will enter the study when in acute flare while the others will enter when they are not in an acute state. Both groups will be followed prospectively. The product of the research would be an improved outcome measure for public policy studies relevant to arthritis.
