Dimensions of the impact of cancer pain in a four country sample: new information from multidimensional scaling

摘要: We investigated the question of how cultural and linguistic backgrounds affect relationships among ratings (reported by patients with metastatic cancer) pain's interference such functions as activity, mood, sleep. Multidimensional scaling (MDS) was used to analyze pain from a sample consisting four culturally linguistically different groups US (n = 1106), France 324), Philippines 267), China 146). Patients all completed Brief Pain Inventory, self-report measure its function. For each these samples, MDS solutions consistently revealed two interpretable dimensions. In one dimension represented other activity. The dimensions were across samples three levels severity ('mild', 'moderate', 'severe'). most prominent when moderate, rather than mild (when little produced) or severe domains highly interfered with). These may have utility in study epidemiology effectiveness treatment. They also be useful clinical assessment describe patterns interference.
