Another aim was to discover the contents and reasons leading individuals to sleep procrastination.

Pearson correlations showed a strong positive relationship (r = .56, p < .001) between sleep procrastination rate and sleep quality, as well as negative relationship with sleep duration (r = -.41, p < .001), strong negative relationship with chronotype (r = -.56, p < .001), and a weak positive relationship with social jet-lag (r = .27, p < .001). Results indicate that the more adolescents procrastinate, the worse sleep quality, shorter sleep duration, higher levels of social jet-lag and evening chronotype,..
