Abstract

Cilj ovog istraživanja bio je ispitati kakav je odnos između tendencije odgađanja, preferencija na dimenziji jutarnjosti-večernjosti i karakteristika spavanja studenata. Ispitivanje je provedeno pomoću internetske ankete na prigodnom uzorku u koji je bilo uključeno 213 studenata oba spola (166 žena) dobi od 18 do 28 godina. Za istražvanje su korišteni Upitnik o navikama spavanja konstruiran za potrebe istraživanja, Kompozitna skala jutarnjosti-večernjosti te dvije mjere odgađanja: Upitnik odgađanja i Upitnik odgađanja odlaska u krevet. Podaci su prikupljeni u ljetnom razdoblju kad studenti nisu imali akademskih obaveza. Utvrđeno je da i u ljetnom razdoblju postoji pomak u rasporedu spavanja između radnih dana i vikenda, ali ne i razlika u trajanju spavanja između te dvije situacije. Nakon odlaska u krevet radnom danom 53% studenata bavilo se nekim aktivnostima u krevetu, dok se vikendom njihov postotak smanjio na 32%, pri čemu aktivnosti uključuju korištenje raznih elektronskih medija. Utvrđena je slaba povezanost Jutarnjosti-večernjosti s odgađanjem (r= -,29) i Odgađanjem odlaska u krevet (r= -,18) te povezanost Odgađanja i Odgađanja odlaska u krevet (r= ,26). U hijerarhijskoj regresijskoj analizi Jutarnjost-večernjost se pokazala značajnim prediktorom vremena odlaska u krevet i vremena početka spavanja radnim danima i vikendom. Odgađanje odlaska u krevet bili su slabo povezani samo s početkom spavanja u radne dane (r= ,16), a u regresiji nisu imali značajan udio s ostalim prediktorima u predviđanju početka spavanja.

Abstract (english)

The goal of this study was to explore the relationship between procrastination tendency, preferences on morningness-eveningness dimension and sleep characteristic of students. The study was conducted by means of internet survey on a convenience sample, which comprised 213 students of both gender (166 females), aged from 18 to 28 years. To perform this study we used Sleep habits questionnaire, which was created for the purposes of this study, Composite Scale of Morningness-Eveningness and two measures of procrastination: Procrastination scale and Bedtime procrastination scale. Data were collected in the summer period when students did not have academic obligations. We found that even in the summer period there was a shift in sleep schedule between weekdays and weekend, but there was no difference in sleep duration between these two situations. A large percentage of students (53%) engaged in some activities after going to bed on weekdays, and this percentage decreases to 32% on weekend. The activities in bed included the usage of electronic media of various kind. We identified weak correlation of Morningness-eveningness with Procrastiantion (r= -.29) and Bedtime procrastination (r= -.18), and weak correlation between Procrastination and Bedtime procrastination (r= .26). In hierarchical regression analysis Morningness-eveningness was a significant predictor of bedtime and sleep start time on weekdays and weekend. Procrastination and Bedtime procrastination were weakly correlated only with the sleep start time on weekdays (r= .16), and in the regression analysis the two measures of procrastination did not significantly contribute to the prediction of falling asleep time.
