The Online Sociability Scale.—
This scale comprises five items, each pertaining to frequencies of different uses of Facebook (e.g., comment on other photographs, sending private messages).
Scores are ratings on a 9-point scale using anchors of 1: Less than once per year and 9: More than once daily (Ross, et al., 2009).
High ratings reflect high frequency of Facebook use.
Cronbach alpha of this scale was .63 in the present study.
