Fibromyalgia, characterized by chronic pain and cognitive impairments, significantly impacts patients' quality of life. Physical exercise has been shown to improve cognitive functions and reduce pain severity. Additionally, positive affect enhances cognitive flexibility and facilitates better adaptation to chronic pain, suggesting that combining physical activity and positive affect could mitigate cognitive deficits in fibromyalgia patients. The objective of this work is to explore the relationship between pain severity and cognitive performance through time spent doing moderate physical activity while taking into account the role of positive affect in fibromyalgia. This prospective study was structured into two phases of evaluation. First, pain severity, positive affect, and time spent performing moderate physical activity were evaluated, and one week later cognitive performance (assessed through the Stroop test) was also evaluated. The final sample consisted of 231 women with fibromyalgia. Moderated mediation analyses were performed using PROCESS. The moderated mediation model showed that the effect of moderate physical activity on the relationship between pain severity and cognitive performance was significant for low levels of positive affect but not for moderate or high levels. That is, the indirect effect of pain intensity on cognitive performance through time spent doing moderate physical activity only has an effect when patients with fibromyalgia present low levels of positive affect. However, there was no significant indirect effect in the simple mediation model. The findings of this study underscore the importance of considering the level of positive affect when examining the impact of moderate physical activity on cognitive performance in women with fibromyalgia.
纤维肌痛以慢性疼痛和认知障碍为特征，严重影响患者的生活质量。体育锻炼已被证明可以改善认知功能并减轻疼痛严重程度。此外，积极情绪可增强认知灵活性并促进对慢性疼痛的更好适应，这表明将体育活动和积极情绪相结合可以减轻纤维肌痛患者的认知缺陷。这项研究的目的是通过进行适度体育活动的时间来探索疼痛严重程度与认知表现之间的关系，同时考虑积极情绪在纤维肌痛中的作用。这项前瞻性研究分为两个评估阶段。首先，评估疼痛严重程度、积极情绪和进行适度体育活动的时间，一周后还评估认知表现（通过斯特鲁普测试进行评估）。最终样本包括231名患有纤维肌痛的女性。使用PROCESS进行调节中介分析。调节中介模型表明，适度体育活动对疼痛严重程度与认知表现之间关系的影响在积极情绪水平较低时显著，但在中等或较高水平时不显著。也就是说，疼痛强度通过进行适度体育活动的时间对认知表现的间接影响仅在纤维肌痛患者积极情绪水平较低时才起作用。然而，在简单中介模型中没有显著的间接影响。这项研究的结果强调了在研究适度体育活动对纤维肌痛女性认知表现的影响时考虑积极情绪水平的重要性。
