To examine the mediating role of pain acceptance (PAcc) between fear of negative evaluation (FNE) and activity avoidance (AV) at different levels of positive affect (PA) (moderator) among women diagnosed with fibromyalgia (FM) (moderate mediation model). This study was cross-sectional in design. A convenience sample of women with FM ( = 231) completed measures of pain severity, FNE, PAcc, AV, and PA. A simple mediation model and a moderate mediation model was constructed and analyzed using the SPSS macro-PROCESS. First, PAcc mediated the effect of FNE on AV (β = .02, = 0.008; [95% CI [0.0075, 0.0394]). Second, a mediated effect of PAcc between FNE and AV moderated by PA at medium and high levels of PA were found (: 0.23; β = -.22, = .0006; : 9.59; β = -.34, = .0002. Future work should seek to validate study findings in diverse samples of FM patients. Additionally, future work should explore how FM self-management interventions that include PAcc can promote increased activity among women suffering from FM with medium to high levels of PA.
本研究旨在探讨在不同积极情绪（PA）水平下（调节变量），纤维肌痛（FM）女性患者中，恐惧负面评价（FNE）与活动回避（AV）之间疼痛接受（PAcc）的中介作用（中等程度的中介模型）。本研究为横断面设计。一个方便的纤维肌痛女性样本（=231）完成了疼痛严重程度、FNE、PAcc、AV 和 PA 的测量。使用 SPSS 宏-PROCESS 构建并分析了简单中介模型和中等程度中介模型。首先，PAcc 中介了 FNE 对 AV 的影响（β=0.02，=0.008；[95% CI [0.0075, 0.0394]）。其次，在中高水平 PA 下，PAcc 在 FNE 和 AV 之间的中介作用受到 PA 的调节（：0.23；β=-0.22，=0.0006；：9.59；β=-0.34，=0.0002）。未来的工作应该在不同的纤维肌痛患者样本中寻求验证研究结果。此外，未来的工作应该探索纤维肌痛自我管理干预措施，包括疼痛接受度，如何促进中高水平 PA 的纤维肌痛女性患者增加活动。
