Method Participants Participants were 438 girls recruited from 18 schools across South Australia, who completed the questionnaire twice, initially (Time 1) when they were in Years 8 and 9 (the first two years of high school) with a mean age of 13.6 years (SD = 0.7), and again two years later (Time 2). The girls were a subset of a larger cross-sectional study (Time 1 N= 1087) investigating Internet use and body image. Attrition was largely due to girls having moved schools or being away on the day of assessment. Measures Facebook Use. Girls were asked whether or not they had a Facebook profile, and if so, how much time they spent on Facebook and how many "friends" they had. These two measures (time, number of friends) have become the most common indicators of level of engage- ment with Facebook.10 Body Image Concerns. Internalization of beauty ideals was measured by three previously used items from the Sociocultural Attitudes Toward Appearance Question- naire.6.12 Body Surveillance was assessed by the Objecti- fied Body Consciousness Scale-Youth.13 Internalization and body surveillance have been suggested as precursors to drive for thinness, 1,14 which was assessed by the Drive for Thinness Scale of the Eating Disorder Inventory as an indicator of the characteristics associated with anorexia nervosa. All scales have demonstrated reliability and validity. 12,13,15
