The Muscle Silhouette Measure (MSM) and Fat Silhouette Measure (FSM) are pictorial scales that assess perceptions of male body image (Frederick et al., 2007). They each contain eight images, with the MSM progressing from non-muscular to very muscular, and the FSM very low body fat to very high body fat. Consistent with self-discrepancy theory (Higgins, 1987), these measures assess men’s perceptions of their current bodies and their ideal bodies, and the discrepancy between these perceptions. It has also been used to assess women’s perceptions of the most attractive male body type and to code representations of muscularity level in popular magazines. The MSM and FSM can be administered to adolescents and/or adults and is free to use. This chapter describes the development and psychometrics of the MSM and FSM. The images were drawn by an artist based on photos of men in the Atlas of Men (Sheldon et al., 1954). Test-retest reliability was high for reports of current and ideal body. It was high for the MSM and moderate for the FSM for the self-ideal discrepancy. The chapter provides the images, response scale, and scoring procedure.
