The effects of stress, anxiety, and depression on rumination, sleep, and fatigue: A nonclinical sample

Data: The study assessed perceived stress, depression, anxiety, rumination, fatigue, sleep (i.e., subjective sleep quality, daytime dysfunction, sleep latency, sleep disturbance, sleep duration, habitual sleep efficiency, and use of sleep medication).

Sample: 229 participants from a community sample answered a survey.

Results: High stress, anxiety, and depression was related to more ruminative thinking, which in turn was related to poor sleep quality; and sleep quality predicted worse fatigue.

Conclusion: Rumination parsimoniously explains the tendency of stress and affective distress to contribute to poor sleep quality, and together with poor sleep, it may also contribute to worse fatigue in some individuals.
