ABSTRACTStudies of correlations between general internet use and psychological well-being have shown mixed results. The present study aimed to elucidate the relationship between Facebook use and psychological well-being, with mental resilience expected to moderate the relationship. Two hundred Israeli adolescents and young adults completed questionnaires assessing their Facebook use, mental resilience, and psychological well-being. Results showed that Facebook use was positively correlated with psychological well-being, and that this relationship was particularly strong for participants with low mental resilience. The findings support a positive effect of Facebook use as providing a virtual supportive community for individuals who may lack the social skills needed to develop social capital and confidence through traditional communication paths.
