Participants were 137 Facebook users who responded to a
request to complete a short online study. The sample
comprised 53 males and 88 females (Mean age = 26.3
years). Participants were recruited through a number of
different methods: postings to the ‘wall’ of three network
homepages on Facebook (two universities, one regional), a
paid flyer shown 10,000 times across all networks, and
links on academic survey websites. The survey was open
during the first two weeks of July 2007.
