Current measures of pain assess the relative contribution of pain in different body regions to the overall impact of pain. We developed a series of questions to measure the relative 'troublesomeness' of pain in different body regions (the "troublesomeness grid"). The study aimed to determine whether the "troublesomeness grid" is an appropriate measure to assess the severity of pain in different body regions, allowing the comparative severity of pain in different body regions to be assessed.
We used data from a pilot for a population survey of pain (N = 205) and from the population survey itself (N = 2504) to assess the 'troublesomeness grid's performance. Specifically, its face and content validity using overall and item non-completion rates; its criterion related validity by exploring the relationship between troublesomeness and standard measures of pain, disability, distress and health utility for the five body regions most commonly affected by chronic pain; and its reliability and reproducibility in a test/re-test study.
The troublesomeness grid appeared to have good face validity as it had good completion rates. It also appeared to have good content validity as the percentage agreement between the grid and the pain manikin was high (over 90%). In terms of criterion related validity, troublesomeness was most strongly correlated with pain intensity and health related quality of life, but less with disability and distress. The test-retest reliability was between 80% and 90% for the majority of body regions examined.
The troublesomeness grid is well completed and appears to be an appropriate tool to assess the comparative severity of pain in different body regions.
目前的疼痛测量方法评估了不同身体区域的疼痛对疼痛总体影响的相对贡献。我们设计了一系列问题来测量不同身体区域疼痛的相对“困扰程度”（“困扰程度网格”）。本研究旨在确定“困扰程度网格”是否是评估不同身体区域疼痛严重程度的合适方法，以便能够评估不同身体区域疼痛的相对严重程度。
我们使用了一项疼痛人群调查试点（N = 205）以及该人群调查本身（N = 2504）的数据来评估“困扰程度网格”的性能。具体而言，通过总体和项目未完成率来评估其表面效度和内容效度；通过探究困扰程度与慢性疼痛最常影响的五个身体区域的疼痛、残疾、痛苦和健康效用的标准测量之间的关系来评估其效标关联效度；并在一项重测研究中评估其信度和可重复性。
“困扰程度网格”似乎具有良好的表面效度，因为其完成率较高。它似乎也具有良好的内容效度，因为该网格与疼痛人体模型之间的百分比一致性很高（超过90%）。在效标关联效度方面，困扰程度与疼痛强度和健康相关生活质量的相关性最强，但与残疾和痛苦的相关性较弱。对于大多数检查的身体区域，重测信度在80%至90%之间。
“困扰程度网格”的完成情况良好，似乎是评估不同身体区域疼痛相对严重程度的合适工具。
