Prospective study of sleep quality and psychological outcomes during COVID-19 home confinement


  • Disrupted sleep was associated with more negative psychological outcomes (rumination, psychotic-like experiences, and somatic symptom severity). Night-to-night variations in subjective sleep quality also predicted individual functioning the following day.

Why this matters

  • To attenuate the global burden of COVID-19, unprecedented home confinement measures and restriction of outdoor activities have been adopted worldwide. This has severely impacted the individuals’ mental and physical health.

  • Cross-sectional studies have identified poor sleep as a risk factor for impaired mental health, but the retrospective and cross-sectional nature of these studies would not address association ‘directionality’.
