Expansion of virtual networks and the Internet has become a major challenge to the traditional forms in which socialization takes place. The aim of this study was to explore the virtual socialization of adolescent students in high schools in Sari, Mazandaran, Iran. The statistical population of this study included all high school students in Sari. The sample population consisted of 380 students selected through multi-stage cluster sampling method. The survey method was used in this research and the data was collected through a questionnaire. The results indicated that the degree to which the students were virtually socialized varied. 64 percent of them showed average socialization, 14 percent high, and 22 percent of them low socialization. The results of multivariate regression analysis, showed that “personal integrity requirements” (β = 0/82), “escape- from- reality requirements” (β =0/4), “social cohesion requirements” (β= 0/35) had greatest impact on the virtual socialization. In addition, the coefficient of determination showed that the independent variables of the study explained 43% of the variance in the dependent variable (virtual socialization). The results also showed that gender did not make a significant difference in the virtual socialization of the adolescent students.
