Association of stress with sleep parameters
We examined if daily stress was associated with the three sleep parameters on the within-person level (e.g. “Is sleep quality lower on nights following days with higher than usual stress?”) and the between person level (e.g. “Do participants with higher average stress levels report worse sleep quality on average?”). To that end, three multilevel models were estimated. Results consistently showed significant associations of daily stress with all three sleep parameters on the between-person level (
