AB  - The main aim of our study was to examine whether there was a relationship between 
      psychological characteristics such as self-efficacy, self-control and chronotype 
      as well as procrastination on the one hand and sleep problems on the other. There 
      were 315 young adults aged between 18 and 27 years (M = 20.57). We used the 
      General Procrastination Scale, the General Self-Efficacy Scale (GSES), Brief 
      Self-Control Scale, the Composite Scale of Morningness (CSM) and the Pittsburgh 
      Sleep Quality Index (PSQI). Our results indicated that low self-efficacy, low 
      self-control and eveningness were positive predictors of procrastination. The 
      reciprocal relationship exists between procrastination and sleep problems. 
      Procrastination positively contributed to sleep problems, whereas sleep problems 
      were a negative predictor of procrastination.
