The Multidimensional Media Influence Scale (MMIS; Cusumano & Thompson, 2001). Media influence and body image in 8–11-year-old boys and girls: A preliminary report on the multidimensional media influence scale. International Journal of Eating Disorders, 29, 37–44) is a child-appropriate, 3-factor scale designed to assess perceived media influence on body image. It has been used in studies exploring the relationship between the entire scale as well as its subscales (awareness, internalization, and pressure) and variables related to body image. However, the 3-factor structure of the scale has never been confirmed via confirmatory factor analysis (CFA), nor has the scale been evaluated with a racially diverse sample of children. This paper reports the results of CFAs establishing the multidimensionality of the scale and the unidimensionality of its subscales among a sample of 661 girls and boys aged 7–12 years, primarily African American and Anglo American. The pressure factor of the MMIS predicted the idealization of a thinner current (child) and future (adult) body both cross-sectionally and one year later for girls and for Anglo American children.

The detrimental effects of media exposure on the body image of adolescents and young adults of both genders have been widely documented (for meta-analyses see Barlett et al., 2008, Grabe et al., 2008 and Groesz et al., 2002). Research on prepubescent child samples is scarcer, but it too points to negative correlations both cross-sectionally and over time between exposure to print and electronic media and satisfaction with the body among both girls and boys (Dohnt and Tiggemann, 2006, Harrison and Bond, 2007 and Harrison and Hefner, 2006).
