The research sample consists of 202 university students studying medicine at Abant Izzet Baysal University. Demographic questions, “UCLA loneliness scale” and “ Internet Cognitive Status Scale (IBSQ)” were used in the study. The results of the questionnaires were transferred to SPSS and Mann Whitney U, Kruskal Wallis H and Spearman correlation analysis were performed. As a result of the analysis, it was observed that men had a sense of solitude more than girls. It has been determined that internet use and the time allocated to the internet is more in men. In addition, the time allocated to the internet, economic situation, age, according to the variables lived in the perception of loneliness and problem with the use of Internet has been seen to be significantly different. According to the scores of the UCLA scale and the IBSQ scale, 92,1% of students have a mild and moderate sense of solitude and 7,9% have a dense sense of Solitude. 88.1% of students use normal and 11,9% problem-free internet. When the scores obtained from the scales were examined, it was found that the scores obtained from the UCLA scale (35.76±7.84) and the scores obtained from the IBD scale (97.14±31.83) were determined. In the correlation analysis, where the impact of Internet use on loneliness perception of the students was measured, it was concluded that there was a weak correlation (R=0.327 and p=0.000) and therefore the problem of Internet use affected loneliness perception even at a low level.
