title: Body-image marking. Validity of body-width estimates as operational measures of body image.
abstract: The relation of image-marking estimates of body width (IM) to actual widths, to other indices of body-size perception, and to measures of body satisfaction were examined using data obtained in a nonclinical sample of 200 women. The results of regression and correlational analyses were as follows: (a) actual widths accounted for only a small proportion of the variance in IM estimates, (b) the variance in IM estimates remaining after actual width was accounted for was not meaningfully related to other body-image indices, and (c) actual widths were more highly correlated with other body-image indices than were differences between estimated and actual widths (IM estimate-actual width). The current results suggest that most of the variance in IM estimates is error variance. Possible methodological confounds, which may bias women's estimates of body widths in the direction of overestimation, are discussed.
