This study examined the extent to which daily mood and stress were associated with pain, health care use, and work activity in 41 adults (mean age=36 years) with sickle-cell disease. Multilevel model analyses of daily diaries (M=91 days) indicated that increases in stress and negative mood were associated with increases in same-day pain, health care use, and work absences. Lagged models suggested bidirectional relationships, with evidence that pain may be the more powerful initiating variable in pain-mood and pain-stress cycles. Of importance, positive mood was associated with lower same-day and subsequent day pain, as well as fewer health care contacts, suggesting that positive mood may serve to offset negative consequences of pain and other illness symptoms.
本研究调查了41名患有镰状细胞病的成年人（平均年龄 = 36岁）的日常情绪和压力与疼痛、医疗保健使用及工作活动之间的关联程度。对每日日记（M = 91天）进行的多水平模型分析表明，压力增加和负面情绪增加与当日疼痛、医疗保健使用及工作缺勤的增加有关。滞后模型显示出双向关系，有证据表明在疼痛 - 情绪和疼痛 - 压力循环中，疼痛可能是更强大的起始变量。重要的是，积极情绪与当日及次日较低的疼痛以及较少的医疗保健接触相关，这表明积极情绪可能有助于抵消疼痛和其他疾病症状的负面后果。
