Eighty patients with a diagnosis of either rheumatoid arthritis, localised osteoarthritis, or generalised osteoarthritis were asked to describe their pain by selecting words from a standardised list of pain descriptors. Words on this list were taken from the sensory class of pain descriptors found in the McGill pain questionnaire. Discriminant analysis was used to identify distinctive characteristics for each of these pain syndromes. On the basis of this analysis verbal responses for each patient were classified into one of the three diagnostic categories. Correct classification occurred in 65% of cases. An estimate of the technique's performance in prospective validation was derived by a split sample approach.
80名被诊断患有类风湿性关节炎、局部骨关节炎或全身性骨关节炎的患者被要求从一份标准化的疼痛描述词列表中选择词汇来描述他们的疼痛。该列表中的词汇取自麦吉尔疼痛问卷中疼痛描述词的感觉类别。采用判别分析来确定每种疼痛综合征的独特特征。基于这一分析，将每位患者的言语反应归类为三种诊断类别之一。65%的病例分类正确。通过拆分样本方法得出了该技术在前瞻性验证中的性能估计值。
