A daily diary study of perceived stress on bedtime procrastination in college students
Objective:To explore the influence of perceived stress on bedtime procrastination in college students,as well as the mediating role of daily ego-depletion and the moderating effect of guilt.Methods:The Per-ceived Stress Scale(PSS-4),State Self-Control Scale(SSCCS)and Bedtime Procrastination Scale(BPS)were used to track the daily perceived stress,ego-depletion and sleep procrastination of 34 college students for 14 days.The 1-1-1 and 2-1-1 multi-layer linear models were constructed by HLM to test the mediating and mod-erating effects.Results:Daily ego-depletion scores played a mediating role in the influence of daily perceived stress scores on daily bedtime procrastination scores(γ20=0.49,P<0.001),guilt scores moderated the effect of daily ego-depletion scores on daily bedtime procrastination scores(γ11=0.03,P<0.05).Conclusion:Daily perceived stress could not only directly predict bedtime procrastination on the night in college students,but also indirectly af-fect daily bedtime procrastination through daily ego-depletion.When ego-depletion is high,guilt can reduce college students'bedtime procrastination.
