The mediating role of cognitive arousal in the relationship between impulsivity and sleep quality among college students: a random intercept cross-lagged panel analysis.

ABSTRACT: Impulsivity, cognitive arousal, and sleep quality are critical factors affecting college students' well-being and academic performance. While impulsivity negatively influences sleep quality, the mediating role of cognitive arousal remains underexplored. The present study assesses how impulsivity affects sleep quality through cognitive arousal. Specifically, it explores whether impulsive behavior heightens cognitive arousal, leading to impaired sleep quality, and whether these relationships hold over time. A longitudinal design was employed, collecting data from 521 college students across three waves over an academic year. Standardized questionnaires were administered to measure impulsivity, cognitive arousal, and sleep quality at each wave. Structural equation modeling and random-intercep
