could buffer the deleterious impact of stress on mental health. Recent studies show that college students are likely to engage in self-disclosure on social network sites (SNSs), but it is unclear to what extent they benefit from doing that. This study examined the effect of self-disclosure on SNSs on young adults' mental health. Survey data were collected from a probability sample of 560 university students. The results show that people tend to open up on Facebook when in times of stress and that self-disclosure on Facebook moderates the relationship between stressful life events and mental health. Facebook disclosure was also positively associated with enacted social support on Facebook, which led to increased perceived social support, enhanced life satisfaction, and reduced depression. SNSs, therefore, serve as a promising avenue for delivering health care and intervention.
