我们研究了文化和语言背景如何影响（转移性癌症患者所报告的）疼痛对活动、情绪和睡眠等功能的干扰程度评级之间的关系这一问题。我们使用多维标度法（MDS）分析了来自美国（n = 1106）、法国（n = 324）、菲律宾（n = 267）和中国（n = 146）四个文化和语言不同群体的样本对疼痛干扰的评级。患者都完成了简明疼痛量表，这是一种对疼痛及其对功能干扰的自我报告测量工具。对于这些样本中的每一个，MDS分析结果都一致地揭示出两个可解释的维度。在所有样本中，一个维度代表情感，另一个维度代表活动。这两个维度在所有四个样本以及三个疼痛严重程度级别（“轻度”“中度”和“重度”）中都能始终如一地得到解释。当疼痛为中度时，这两个维度最为显著，而不是在轻度（几乎没有产生干扰时）或重度（所有方面都受到高度干扰时）。这些维度可能在疼痛流行病学研究以及疼痛治疗效果研究中有用。它们在临床评估中描述不同的疼痛干扰模式时可能也有用。
We investigated the question of how cultural and linguistic backgrounds affect relationships among ratings (reported by patients with metastatic cancer) of pain's interference with such functions as activity, mood, and sleep. Multidimensional scaling (MDS) was used to analyze ratings of pain interference from a sample consisting of four culturally and linguistically different groups from the US (n = 1106), France (n = 324), the Philippines (n = 267), and China (n = 146). Patients all completed the Brief Pain Inventory, a self-report measure of pain and its interference with function. For each of these samples, MDS solutions consistently revealed two interpretable dimensions. In all samples, one dimension represented affect and the other dimension represented activity. The dimensions were consistently interpretable across all four samples and across three levels of pain severity ('mild', 'moderate', and 'severe'). The dimensions were most prominent when pain was moderate, rather than mild (when little interference was produced) or severe (when all domains were highly interfered with). These dimensions may have utility in the study of the epidemiology of pain and of the effectiveness of pain treatment. They may also be useful in clinical assessment to describe different patterns of pain interference.
