Low back pain patients' responses to the McGill Pain Questionnaire (MPQ) were factor analyzed using the principal factor method and direct oblique rotation procedures. Four factors were extracted that accounted for 55% of the total variance. Coefficients of congruence were computed in order to relate the current factors with those extracted in a previous factor analytic investigation. The results provided positive evidence that the sensory pressure, evaluative, and affective-sensory factors that were previously identified are stable dimensions underlying the MPQ responses of low back pain patients. However, it is necessary to conduct further cross-validation studies using patients from a wide variety of treatment settings.
采用主因子法和直接斜交旋转程序，对下背痛患者对麦吉尔疼痛问卷（MPQ）的反应进行了因子分析。提取了四个因子，它们占总方差的55%。计算了一致性系数，以便将当前因子与先前因子分析研究中提取的因子联系起来。结果提供了积极的证据，表明先前确定的感觉压力、评价和情感感觉因子是下背痛患者MPQ反应的稳定维度。然而，有必要使用来自各种治疗环境的患者进行进一步的交叉验证研究。
