Thin-ideal (or media) internalization is an important eating disorder risk factor that has become a central target of many prevention programs. However, evidence for its valid assessment in young, mixed-gender, adolescent samples is limited, and the current study is the first published to explore the psychometric properties of the 30-item Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3: Thompson, van den Berg, Roehrig, Guarda, & Heinberg, 2004) in a non-adult community sample. Two samples of Grade 8 students (M age = 13.68 years, SD = .39), totalling 680 girls (N =332) and boys (N =348) completed the SATAQ-3 and other measures, whereas a smaller sample (N = 123) of Grade 10 females (M age = 15.01 years, SD = .41) served as a comparison group for supplementary analyses. Principal component analyses (PCA) with data from Sample One (N=201) revealed four factors with eigenvalues >1.0, similar to the original authors structure but where some cross-loading occurred between the Pressures and Internalization – General scales. Confirmatory factor analyses (CFA) were conducted with data from Sample Two (N=479) on the factor solution found in the PCA. The model did not fit well, leading to further revisions based on removal of cross-loading items and CFA modification indices, resulting in a 19-item, 4 factor solution with acceptable fit. Examinations of validity and reliability were generally acceptable. The overall findings suggest an abbreviated version of the SATAQ-3 might be more appropriate than the original version with young-adolescent, mixed gender audiences. Further examinations of the psychometric properties of the SATAQ-3 with this demographic are indicated.
