采用元分析技术研究疼痛强度的自我报告和疼痛行为的直接观察之间的关系。对29项研究和85个效应量的总体效应量估计产生了中度正相关，z = 0.26。研究之间的高度变异性允许进行随机效应调节分析，该分析确定了疼痛的长期性、疼痛评估的时间、疼痛行为整体测量的使用以及疼痛部位，显着调节了疼痛强度的自我报告与直接观察之间的关系。疼痛行为。这些发现表明，当被研究的个体有急性疼痛时，疼痛强度的自我报告和疼痛行为的直接观察更可能彼此显著相关（z = 0.35），在观察疼痛行为后不久收集疼痛强度数据的自我报告时（z = 0.40），当使用全局复合测量来量化疼痛行为时（z = 0.37），以及当被观察的人患有慢性腰痛时（z = 0.30）。其他因素没有被发现是显着的主持人包括：观察员培训的程度，疼痛诱导任务的相关性，和疼痛行为观察措施。疼痛的评估结果的影响进行了讨论。(C)2003年国际疼痛研究协会。由Elsevier Science B.V.出版，版权所有。
Meta-analytic techniques were utilized to investigate the relationship between self-reports of pain intensity and direct observations of pain behavior. Estimation of the overall effect size from 29 studies and 85 effect sizes yielded a moderately positive association, z = 0.26. High variability across studies permitted a random-effects moderator analysis that determined chronicity of pain, the timing of the pain assessment, the use of global measures of pain behavior, and pain site significantly moderate the relationship between self-reports of pain intensity and direct observations of pain behavior. These findings indicate that self-reports of pain intensity and direct observations of pain behavior are more likely to be significantly related to each other when the individual being studied has acute pain (z = 0.35), when the self-report of pain intensity data are collected soon after the observation of pain behavior (z = 0.40), when global composite measures are used to quantify pain behavior (z = 0.37), and when the person being observed suffers from chronic low back pain (z = 0.30). Other factors not found to be significant moderators include: extent of observer training, relevance of the pain-inducing task, and pain behavior observation measure used. The implications of the findings for the assessment of pain are discussed. (C) 2003 International Association for the Study of Pain. Published by Elsevier Science B.V. All rights reserved.
