Paper Summary
This study focuses on 'bedtime procrastination.'
As the name suggests, this refers to going to bed later than planned, and it is said to be one of the factors contributing to sleep deprivation.
This study examines the relationship between bedtime procrastination and:
• Sleep duration, sleep deprivation, fatigue, and depression
• Chronotype (morningness-eveningness, etc.)
• Self-control
Findings
As a result of correlation analysis, the following relationships were observed with bedtime procrastination:
• Negative correlation with sleep duration
• Positive correlation with sleep deprivation
• Positive correlation with fatigue and depression
Furthermore, the results of multiple regression analysis showed:
• A negative main effect from self-control
• A positive main effect from chronotype
Regarding the coefficients, the effect of self-control was larger than that of chronotype, indicating that it has a stronger influence.
From these results, it is considered that:
• While biological chronotype influences bedtime procrastination, self-control also plays a role, andimproving self-control is required for improvement
is considered.
Although the paper does not mention specific intervention methods,
