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.
我们研究了文化和语言背景如何影响（转移性癌症患者报告的）疼痛对诸如活动、情绪和睡眠等功能的干扰程度评分之间的关系。多维尺度分析（MDS）被用于分析来自美国（n = 1106）、法国（n = 324）、菲律宾（n = 267）和中国（n = 146）四个文化和语言背景不同的群体样本的疼痛干扰评分。患者均完成了简明疼痛问卷，这是一种关于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解决方案始终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。这些维度在所有四个样本以及疼痛严重程度的三个水平（“轻度”、“中度”和“重度”）上都始终是可解释的。当疼痛为中度时，这些维度最为突出，而非轻度（此时产生的干扰较小）或重度（此时所有领域都受到高度干扰）。这些维度可能在疼痛流行病学研究和疼痛治疗效果研究中具有实用价值。它们在临床评估中也可能有助于描述不同的疼痛干扰模式。
