title: Body image of sexually and physically abused children.
abstract: Body size perception was measured in 41 children aged 6-10 who had been either sexually or physically abused, or had no history of abuse. Two psychophysical methods were used, including the staircase method and a signal detection method. In the staircase methodology, children adjusted the direction of distortion of their continuously changing body size. In the signal detection method, children made judgments about the presence or absence of size distortion in presented images. Results using the staircase method indicated children overestimated their body sizes, with no differences between abuse conditions, gender, or age. For the signal detection methodology, no difference in ability to detect the presence/absence of size distortion (d') was found between abuse conditions, although females were less accurate than males. All groups were better able to detect distortion when the image was distorted too wide. Measures of response bias (Ln beta) indicated that sexually abused children had a greater bias to report size distortion as present, as compared with the physically abused children.
