Abstract
Facebook has become the most popular social networking site round the world. In seeking an explanation for this phenomenon, individual differences in circadian functioning seem to be an interesting issue. The main aim of this study was to examine the potential associations between morningness/eveningness and Facebook use (intrusion and intensity). The participants were 663 Facebook users. The Facebook Intrusion Questionnaire, Facebook Intensity Scale and the Composite Scale of Morningness were used. Our results indicate that chronotype is negatively related with Facebook usage. Eveningness people use Facebook intensively and their Facebook use is more intrusive. Moreover, eveningness in combination with young age predicted Facebook intensity.
