This study examined the relationship between loneliness and various aspects of Facebook use including use activity, self-disclosure, attitudes, and satisfaction. Data were collected through an online survey among adult Facebook users (N = 536). Results revealed that loneliness was associated with a fewer number of Facebook friends and a less overlapping between Facebook and offline friends. Loneliness was inversely related to communicating activities but not significantly to presenting activities. Also, lonely people tended to engage in positive self-disclosure less but negative self-disclosure more. Although lonely people viewed Facebook as more useful for self-disclosure and social connection, their satisfaction of Facebook use was lower than their counterparts.
