Abstract
It has been documented that characteristics of personality influence estimation of subjective sleep feeling in the morning. This study examines the relationship between Neuroticism (N score) and Extraversion-Introversion (E score) on the Maudsley Personality Inventory (MPI) and subjective sleep feeling measured by the MA version of the OSA sleep inventory (OSA-MA), which consists of 20 items and 5 factors.
Subjects aged 25--59 were instructed to complete the OSA-MA on a weekday morning. One hundred and ten (53 male) healthy day- workers were selected for further analysis. They were divided into 2 groups (high and low) on the basis of N and E scores on the MPI. Factor scores of OSA-MA were compared between these groups. Subjects with high N scores had low evaluation of factors such as sleepiness at rising, sleep onset-sleep maintenance and fatigue recovery. There were no differences in any of the OSA-MA factors between high and low group of E scores. These results suggest that neuroticism influence the estimation of sleep quality and mood at rising.
