帕金森氏病问卷（PDQ-39）是一种针对疾病的健康状况测量方法，涵盖健康不良的八个方面，包含39个问题。问卷调查的发展已在其他地方全面概述，本文简要概述。这里使用了心理测量技术，从PDQ-39中得出一个单一指数，转换成从0（健康良好）到100（健康状况不佳）的分数范围。然后从PDQ-39中选择一个子项目集来创建一个较短的版本，PDQ-8。所选择的每个项目都是与它所贡献的整体领域得分最高度相关的项目：在多个项目与总得分同等强烈相关的情况下，则选择获得最高完成率的项目。这些项目被加在一起，并转换成从0到100的分数。用PDQ-39与PDQ-8的单指标计算结果进行了比较，发现两者非常相似。如果需要较短形式的测量，并且可以接受或需要对整体健康状况进行单一指数测量，则建议使用PDQ-8而不是PDQ-39。
The Parkinson's Disease Questionnaire (PDQ-39) is a disease specific measure of health status which covers eight dimensions of ill-health, and contains 39 questions. The development of the questionnaire has been outlined in full elsewhere and is briefly outlined in this paper. Psychometric techniques are used here to derive a single index figure from the PDQ-39, transformed to a score range from 0 (good health) to 100 (poor health). A sub-set of items is then selected from the PDQ-39 to create a shorter form version, the PDQ-8. Each item selected is the one most highly correlated with the overall domain score to which it contributes: in cases where more than one item correlated equally strongly with the total then the item which received the highest completion rate was selected. The items were summed together and transformed onto a score from 0 to 100. The results gained from the single index gained from the PDQ-39 are compared with that gained from the PDQ-8, and are found to be remarkably similar. The use of the PDQ-8 is recommended over the PDQ-39 where a shorter form measure is required and where a single index measure of overall health status is acceptable or desirable.
