Sixty-nine postoperative patients indicated the severity of their pain using eight measures designed to assess pain intensity and two designed to measure pain affect. The utility and validity of the 10 measures were evaluated according to two criteria: (a) the magnitude of the relationship between each scale and a linear combination of the pain measures, and (b) relative rates of incorrect responding. The results indicate that each of the measures of pain intensity is adequately valid. In addition, this sample of patients failed to differentiate pain intensity and pain affect using the present measures, suggesting the need for additional research to explore the validity of the affective measures employed in the study. The 11-point Box Scale (BS-11) of pain intensity demonstrated the strongest relationship to a linear combination of all of the measures employed and was responded to correctly by each subject in the sample. All else being equal, these results suggest that the BS-11 scale may be the most useful clinical index of pain intensity among postoperative patients.
69名术后患者使用八项旨在评估疼痛强度的指标和两项旨在测量疼痛感受的指标来表明其疼痛的严重程度。根据两个标准评估这10项指标的效用和有效性：（a）每个量表与疼痛指标线性组合之间关系的大小，以及（b）错误反应的相对发生率。结果表明，每项疼痛强度指标都具有充分的有效性。此外，该患者样本未能使用当前指标区分疼痛强度和疼痛感受，这表明需要进行更多研究来探索该研究中所采用的情感指标的有效性。11点疼痛强度盒式量表（BS - 11）与所采用的所有指标的线性组合显示出最强的关系，且样本中的每个受试者都能正确作答。在其他条件相同的情况下，这些结果表明，BS - 11量表可能是术后患者疼痛强度最有用的临床指标。
