The reliability and validity of a group-administered version of the body image assessment.

Abstract

The Body Image Assessment (BIA) is a simple measure of body image disturbance. However, it has currently only been used with an individual administration format and only to assess ratings of current body size, ideal body size, and body dissatisfaction. It has also only been validated for use with women. In the current two studies, the reliability and validity of a group-administered version of the BIA procedure for both men and women that also assessed ratings of the ideal opposite sex and predictions about what the opposite sex would prefer as most attractive was examined. In the first study, results indicated good test-retest reliability for the group version for current and ideal body size and good concurrent validity with the individual administration format of the BIA. The results of the second study supported the construct and predictive validity of the group administered BIA, suggesting that it is a time-efficient alternative to the original, individually administered assessment.
