The figure rating scale (FRS), also known as the Stunkard scale, is a psychometric measurement originally developed in 1983 to communicate about the unknown weights of a research subject's absent relatives, and since adapted to assess body image. The scale presents nine male and nine female schematic silhouettes, ranging from extreme thinness to extreme obesity. For research purposes, each participant is asked to self-select the silhouette that best indicates his or her current body size and the silhouette that reflects his or her ideal body size (IBS).
