Previous research suggests that longer-term perceived ostracism is related to poor sleep quality. In this study, we investigated the mediating effect of cognitive arousal on the perceived ostracism-sleep quality relationship. We also investigated whether experiential avoidance was a moderator of the cognitive arousal-sleep quality relationship. Participants (N = 251) were recruited through online research portals to take part in an online survey. A path analysis was used to test a moderated mediation effect between variables. It was found that cognitive arousal mediated the perceived ostracism-sleep quality relationship; however, experiential avoidance was not a significant moderator. These findings suggest that further research needs to be conducted to elucidate the mechanism of experiential avoidance to account for when it may impact sleep quality. Moreover, treatment interventions targeted at reducing cognitive arousal (e.g., cognitive behavioural therapy) prior to sleep are likely to bear some fruit.
先前的研究表明，长期被排斥的感知与睡眠质量差有关。在这项研究中，我们调查了认知唤醒对被排斥感知与睡眠质量关系的中介作用。我们还研究了经验回避是否是认知唤醒与睡眠质量关系的调节因素。参与者（N=251）通过在线研究门户招募，参与在线调查。路径分析用于测试变量之间的调节中介效应。结果发现，认知唤醒中介了被排斥感知与睡眠质量的关系；然而，经验回避并不是一个显著的调节因素。这些发现表明，需要进一步研究以阐明经验回避的机制，以说明它何时可能影响睡眠质量。此外，在睡前进行旨在降低认知唤醒的治疗干预（例如，认知行为疗法）可能会产生一些效果。
