Findings: The results of convergent and divergent validity, composite reliability, Cronbach's alpha, average variance extracted, factor analysis, Stone-Geisser's criterion, goodness of fit, and independent t-test revealed that there was a significant relationship between all the components of social health (i.e. social integration, social coherence, social actualization, social acceptance, and social contribution) and the usage of social networks. Accordingly, social health explains 42% of the usage of social networks. As regards the components, the percentages are social integration (86%), social coherence (52%), social actualization (25%), social acceptance (44%), and social contribution (36%).
