Sleep Reactivity Amplifies the Impact of Pre-Sleep Cognitive Arousal on Sleep Disturbances.

ABSTRACT: Sleep reactivity-an individual's susceptibility to sleep disruptions due to stress-has been linked to increased insomnia risk. Investigating how sleep reactivity moderates the 'stress → pre-sleep arousal → sleep' pathway may help mitigate sleep disturbances and enhance treatment outcomes. In the present study, full-time university students without sleep disorders completed the Ford Insomnia Response to Stress Test (FIRST), which assesses sleep reactivity. From 264 students, 30 students with the lowest and 30 with the highest FIRST scores were selected for further study. They provided daily actigraphy, Pre-sleep Arousal Scale ratings, pre-sleep heart rate (via an ŌURA ring), and perceived stress scores over 2 weeks. Multilevel moderated mediation analyses were conducted using 800 nights of
