Abstract

Objective

The present study was conducted to examine the impact of experimentally-manipulated perceptions of sleep on self-reported affective reactivity and recovery from a social stressor in undergraduate students.

Design

The study design is experimental, as the participants were randomly assigned to either good or poor perceived sleep quality conditions.

Main outcome measures

The impact of condition on self-reported affective responses to and recovery from the social stressor were assessed as well as whether the observed effects were moderated by stress, rumination, and depression.

Results

Participants in the good sleep condition reported increased negative affect (NA) after the social stressor and after a six-minute recovery period relative to participants in the poor sleep condition; participants in the former condition also reported heightened NA post-recovery relative to baseline (a comparison that was non-significant for participants in the poor sleep condition). The effect of condition on NA post-stressor and post-recovery was moderated by depression and rumination, with important implications for participants in the good sleep condition in particular.

Conclusions

These findings may have resulted from participant expectations about the impacts of sleep on their behaviour, although additional research remains to be conducted to identify the mechanism responsible for the obtained pattern of results.

实验操纵的对良好睡眠的看法预示着大学生对社会压力源的反应性更强，恢复能力更差

摘要

客观的

本研究旨在检查实验操纵的睡眠感知对大学生自我报告的情感反应和从社会压力源中恢复的影响。

设计

该研究设计是实验性的，因为参与者被随机分配到良好或较差的感知睡眠质量条件。

主要观察指标

评估了条件对自我报告的对社会压力源的情感反应和恢复的影响，以及观察到的影响是否受到压力、反刍和抑郁的影响。

结果

与睡眠条件差的参与者相比，睡眠条件良好的参与者在社交压力源和六分钟恢复期后的负面影响（NA）增加；前一种情况的参与者还报告说，相对于基线，恢复后的 NA 升高（这种比较对于睡眠条件差的参与者而言并不显着）。条件对 NA 压力源后和恢复后的影响受到抑郁和反刍的影响，特别是对睡眠条件良好的参与者具有重要意义。

结论

这些发现可能源于参与者对睡眠对其行为的影响的期望，尽管仍有待进行进一步的研究以确定导致所获得结果模式的机制。
