Daily variation in sleep quality is associated with health-related quality of life in people with spinal cord injury

This study examined how day-to-day changes in sleep quality affect the health-related quality of life (HRQOL) in people with spinal cord injury (SCI). The study used ecological momentary assessment and end-of-day diaries to collect sleep and HRQOL data over 7 days, minimizing recall bias and capturing real-time experiences. The goal was to understand how sleep impacts daily life aspects such as pain, fatigue, mental health, cognitive function, and social participation in individuals with SCI.

• 1
  Better sleep quality over the course of a week was associated with better HRQOL across all assessed domains.
• 2
  Within an individual, sleep quality was related to other reports of sleep (Sleep Disturbance, Sleep-Related Impairment and Fatigue) and cognition, but not to other aspects of HRQOL.
• 3
  The relationships between sleep quality and daytime symptoms (pain, fatigue and subjective thinking) were strongest in the morning but weakened over the day.
