Pre-sleep Arousal as a Mediator of Relationships Among Worry, Rumination, and Sleep Quality
The purpose of this research was to examine the relationship between rumination, worry, pre-sleep arousal, and sleep quality. The participants were 202 young adults who completed questionnaires on sleep quality, trait rumination, and worry. After factor analysis of rumination and worry scales, three factors were found and which were positively correlated with pre-sleep cognitive arousal and sleep quality. The results of structural equation model analysis suggested that pre-sleep arousal is a mediator of the effects of repetitive thought on sleep quality. Dwelling on the negative and worry engagement can predict higher pre-sleep arousal which can predict poor sleep quality. Pre-sleep arousal is the key factor in the relationship between repetitive thought and sleep quality.
