Facebook also has the potential to create realworld problems that did not previously exist.
On examining the role played by Facebook in romantic relationships, for example, Muise et al. (2009) found that site use can lead to increased jealousy and/or obsessive behavior, as a result of the opportunities it provides users to “access . . . information about their partner that would not otherwise be accessible” (p. 443). This, in turn, positively reinforces ongoing “surveillance behavior” (p. 444). Muise et al. (2009) found that participants were able to reflect objectively on this vicious cycle, but often were unable to break it, citing its addictive nature. Indeed, an overreliance on Facebook more generally may mean that cessation of use can have a negative impact: Sheldon and Hinsch (as cited in Sheldon et al., 2011) found that reduction in use correlated with “reduced aggression, procrastination, and negative affect , and with increased life-satisfaction, but it was also associated with reduced positive affect”
(Sheldon et al., 2011, p. 773).
