纤维肌痛患者报告说，与健康对照组相比，睡眠障碍更大，这导致了他们在分开的注意力任务中的准确性降低。与健康的、无痛的对照组相比，纤维肌痛患者的认知能力受到了损害。睡眠障碍、焦虑和抑郁在纤维肌痛患者中非常普遍，每一种都与认知能力受损有关。然而，有限的工作探索了心理社会因素是否会导致群体认知表现的差异。这项次级数据分析调查了纤维肌痛患者和健康对照组之间认知表现的差异，以及心理社会因素是否解释了这些差异。患有纤维肌痛的成年人(N=24)和健康的无疼痛对照组(N=26)完成了两项认知任务和患者报告的结果测量信息系统睡眠障碍、焦虑和抑郁的简短形式。独立样本t检验被用来检验纤维肌痛患者和健康对照组之间认知能力的差异。皮尔逊相关性被用来检验心理社会因素和认知表现之间的联系。与认知绩效显著相关的心理社会因素被探索为群体认知绩效差异的潜在中介因素。与健康对照组相比，纤维肌痛患者对注意力分离的准确性较差，睡眠障碍导致了这一组差异。在注意力转换任务上，与纤维肌痛患者相比，健康对照组显示出更大的转换成本，但在反应时方面没有组间差异。焦虑和抑郁与认知表现无关。我们发现，纤维肌痛患者报告的睡眠障碍更大，进而在分开的注意力任务上的准确性较差。睡眠障碍可以通过认知行为治疗等行为干预措施来改变，并可能成为改善纤维肌痛患者睡眠质量和认知能力的目标。
Patients with fibromyalgia reported greater sleep disturbance, which contributed to reduced accuracy on a divided attention task compared with healthy controls. Patients with fibromyalgia show impaired cognitive performance compared with healthy, pain-free controls. Sleep disturbance, anxiety, and depression are highly prevalent among patients with fibromyalgia, and each is associated with impaired cognitive performance. Yet, limited work has explored whether psychosocial factors contribute to group differences in cognitive performance. This secondary data analysis investigated differences in cognitive performance between patients with fibromyalgia and healthy controls, and whether psychosocial factors accounted for these differences. Adults with fibromyalgia (N = 24) and healthy, pain-free controls (N = 26) completed 2 cognitive tasks and the Patient-Reported Outcomes Measurement Information System sleep disturbance, anxiety, and depression short forms. Independent samples t tests were used to test for differences in cognitive performance between patients with fibromyalgia and healthy controls. Pearson correlations were conducted to examine associations between psychosocial factors and cognitive performance. Psychosocial factors significantly related to cognitive performance were explored as potential mediators of group differences in cognitive performance. Patients with fibromyalgia demonstrated poorer accuracy for divided attention compared with healthy controls, and sleep disturbance mediated this group difference. On the attentional switching task, healthy controls showed a greater switch-cost for accuracy compared with patients with fibromyalgia, but there was no group difference in reaction time. Anxiety and depression were not related to cognitive performance. We found that patients with fibromyalgia reported greater sleep disturbance and, in turn, had poorer accuracy on the divided attention task. Sleep disturbance is modifiable with behavioral interventions, such as cognitive behavioral therapy, and may be a target for improving sleep quality and cognitive performance among patients with fibromyalgia.
