摘要:It is examined if the relationship empirically demonstrated between health and face-to-face social interactions is confirmed when it is virtual. The objective is to know if the perception of psychological well-being and receiving social support would explain the frequency of participation in virtual social networks (VSN). An ex-post-facto design was applied to a sample of 510 university Internet users (age, M = 22.89, SD = 5.67, 78.9% women). The level of psychological well-being (Spanish adaptation of the Ryff Psychological Well-Being Scale), social support (Family Social Support and Friends questionnaire - AFA) and the frequency of use of VSN are evaluated. To determine the relationships between the variables, correlation and hierarchical regression analyzes were carried out. The relative contribution of the perception of psychological well-being and of obtaining social support in the frequency of VSN use is confirmed, controlling the influences of age and gender. Specifically, the perception of having less ability to dominate the social environment and to obtain social support for friendships through VSN explains and allows predicting the increase in the frequency of use of such networks.
