METHOD: meta-analysis of 24 studies examining the uses and gratifications of Facebook, and nine studies of Facebook addiction.
RESULTS: The most popular motives for Facebook use are relationship maintenance, passing time, entertainment, and companionship. Facebook addiction is when use becomes excessive or motivated by a desire for mood alteration.
CONCLUSIONS: Research currently is too limited to establish links between normal Facebook use and Facebook addiction.
