已知调节情感的个体差异会影响类风湿关节炎的疼痛和其他症状。然而，还没有研究使用严格的每日日记方法来解决当积极或消极的影响得到有效调节时，当前疼痛是否会减轻的问题。我们采用了前瞻性的、重复的每日抽样设计，从情感强度的日常变化中推断情感的调节，并研究了这些情感变化与类风湿关节炎疼痛的前瞻性相关性。94名被诊断患有类风湿性关节炎的成年患者在30天内完成了疼痛和积极和消极情绪的日常测量。在医学评估期间收集人口统计学和疾病状态变量的信息。分层线性模型分析的结果表明，从前一天到当天的积极和消极影响的调节预测当天疼痛的显著减少，导致疼痛强度降低高达28%。这些发现部分受到疾病状态和人口统计学变量的影响。这项研究表明，消极和积极影响的日常调节是了解类风湿关节炎患者疼痛体验的关键变量，也是干预的潜在重要目标。(C)2007年国际疼痛研究协会。Elsevier B.V.出版，保留所有权利。
Individual differences in the regulation of affect are known to impact pain and other symptoms in rheumatoid arthritis. However, no studies have yet used a rigorous daily diary methodology to address the question of whether current pain is reduced when positive or negative affects are effectively regulated. We used a prospective, repeated daily sampling design to infer the regulation of affect from day-to-day changes in affect intensity and examined how these changes in affect were prospectively related to pain from rheumatoid arthritis. Ninety-four adult patients diagnosed with rheumatoid arthritis completed daily measures of pain and positive and negative affect over a period of 30 days. Information on demographic and disease status variables was collected during a medical evaluation. Results of hierarchical linear model analyses indicated that the regulation of both positive and negative affect from the prior day to the current day predicted significantly greater decreases in pain that day, resulting in up to a 28% reduction in pain intensity. These findings were partly influenced by disease status and demographic variables. This study suggests that the day-today regulation of negative and positive affect is a key variable for understanding the pain experience of individuals with rheumatoid arthritis and is a potentially important target for intervention.
