8名牙医观看了标准化的录像带，录像带显示了对颞下颌关节和咀嚼肌肉的触诊，并记录了他们对患者所经历的疼痛程度的判断。使用四点言语描述量表（VDS）（“无”、“轻度”、“中度”、“严重”疼痛）或100毫米视觉模拟量表（VAS）记录判断，其中固定了“无疼痛”和“可能的最严重疼痛”这两个术语。计算每个量表一周内的测/重测信度和判断间信度；根据加权kappa和类内相关系数的统计等效性，直接比较两个量表的信度。两种量表均显示令人满意的信度。VDS的中位测试/重测试信度为k = 0.590， VAS的中位测试信度为r = 0.822。裁判员间信度对于VDS平均k = 0.394, r = 0。VAS是735。直接比较两种量表的信度显示两种量表都没有明显的优势。当牙医用这些量表量化病人的疼痛时，这些量表的边际可靠性表明，这两种量表都不应被视为“客观”的疼痛测量。
Eight dentists viewed standardized videotapes showing palpations of the temporomandibular joint and muscles of mastication and recorded their judgments concerning the amount of pain the patient was experiencing. Judgments were recorded using a four-point verbal descriptor scale (VDS) ("none", "mild", "moderate", "severe "pain) or a 100-mm visual analog scale (VAS) anchored with the terms "no pain" and "worst pain possible". Test/re-test reliability over a one-week period and interjudge reliabilities were calculated for each scale; reliabilities of the two scales were directly compared based on the statistical equivalence of weighted kappa and the Intraclass Correlation Coefficient.Neither scale showed satisfactory reliability. Median test/re-test reliabilities were k = 0.590 for the VDS and r = 0.822 for the VAS. Interjudge reliabilities averaged k = 0.394 for the VDS and r = 0. 735 for the VAS. Direct comparison of reliabilities for the two scales showed no clear advantage for either scale. The marginal reliabilities of these scales, when used by dentists to quantify the patient's pain, suggest that neither scale should be regarded as an "objective" pain measure.
