A study was undertaken at six chiropractic college outpatient (teaching) clinics and 60 private chiropractic clinics, to evaluate the comparability of patients' pain quality and pain intensity in each of three low back pain diagnostic groups. The McGill Pain Questionnaire (MPQ) was employed for this purpose. There was a tremendous range of measurable pain characteristics (Pain Rating Index scores) within the three diagnostic groups in both patient samples. Overall, patients of field doctors had higher mean scores on all dimensions of pain quality measured by the MPQ, and they described a higher pain intensity than patients attending the teaching clinics. In all three diagnostic groups, patients attending teaching clinics were more likely than private patients to present with a chronic low back condition. Although patients in the field more frequently used words implying greater pain intensity, the characteristics of pain quality (descriptor profiles) showed similar trends among the two patient samples. The consistent findings of less pain intensity among teaching clinic patients support previous reports that these patients have milder complaints than patients seen by field doctors. While these findings do not rule out the use of teaching clinic patients as subjects in clinical trials, it is suggested that generalizations from teaching clinic patients to private patients should be made with caution.
一项研究在六家脊椎按摩疗法学院门诊（教学）诊所和60家私人脊椎按摩疗法诊所开展，以评估三个下背痛诊断组中每组患者疼痛性质和疼痛强度的可比性。为此采用了麦吉尔疼痛问卷（MPQ）。在两个患者样本的三个诊断组中，可测量的疼痛特征（疼痛评级指数得分）范围极大。总体而言，在MPQ测量的疼痛性质的所有维度上，私人诊所医生的患者平均得分更高，并且他们描述的疼痛强度高于教学诊所的患者。在所有三个诊断组中，与私人患者相比，教学诊所的患者更有可能患有慢性下背痛。尽管私人诊所的患者更频繁地使用暗示疼痛强度更大的词汇，但在两个患者样本中，疼痛性质的特征（描述符概况）显示出相似的趋势。教学诊所患者疼痛强度较小这一一致发现支持了先前的报告，即这些患者的主诉比私人诊所医生诊治的患者更轻。虽然这些发现不排除将教学诊所的患者用作临床试验的受试者，但建议从教学诊所的患者推广到私人患者时应谨慎。
