A three-item semantic differential scale assessing a person's perception of a target individual's body size relative to themselves. Items capture perceptions across the overweight-underweight, obese-thin, and heavier-thinner dimensions in comparative terms. Designed as a manipulation check for body size stimuli in experimental research, the scale measures perceived relative body size rather than absolute body size estimation, making it appropriate for designs that manipulate social comparison targets or model body types.
