The objective of this research was to assess Internet addiction among students of the Faculty of Health Prevention at the Medical University of Białystok. The present study included 358 students-nursing (n = 232), midwifery (n = 71), and medical rescue (n = 55). The following instruments were administered to the participants:the Young test, a test of the intensity of the abstinence syndrome, and a test of "online" addiction. Students who did not have a computer at home spent 3 hours a day on the Internet; students who did have a computer at home spent 0.5 to 8hours.
