Emerging research suggests that psychological inflexibility may be a factor contributing to the development and maintenance of insomnia. However, less is known about the potential cognitive pathways that may explain this relationship. In this study, we investigated the serial mediating effects of psychological inflexibility and daytime insomnia-related rumination on the association between dysfunctional beliefs and attitudes about sleep (DBAS) and insomnia symptoms. The sample included 490 college students who underwent assessments at two time points over a 1-month period. The results of our mediational tests yielded significant indirect effects, supporting the prediction that psychological inflexibility and daytime insomnia rumination serially mediate the relationship between DBAS and insomnia. The study provides insights into potential mechanisms for insomnia, emphasizing the role of psychological inflexibility in perpetuating maladaptive cognitive processes associated with insomnia. Future researchers should explore other maladaptive responses to insomnia-related concerns and distress, such as worry and safety behaviors, and replicate findings in clinically elevated insomnia samples.
新兴研究表明，心理灵活性不足可能是导致失眠发生和持续的一个因素。然而，对于可能解释这种关系的潜在认知途径，我们了解得较少。在本研究中，我们调查了心理灵活性不足和白天与失眠相关的反刍思维在关于睡眠的功能失调信念和态度（DBAS）与失眠症状之间的关联中的系列中介作用。样本包括490名大学生，他们在1个月的时间内接受了两个时间点的评估。我们的中介测试结果产生了显著的间接效应，支持了心理灵活性不足和白天失眠反刍思维系列中介DBAS与失眠之间关系的预测。该研究为失眠的潜在机制提供了见解，强调了心理灵活性不足在使与失眠相关的适应不良认知过程持续存在方面的作用。未来的研究人员应该探索对与失眠相关的担忧和困扰的其他适应不良反应，如担忧和安全行为，并在临床上失眠程度较高的样本中重复这些发现。
