Body Image Assessment Tools

Don Williamson, PhD

The Body Image Assessment (BIA) tools available from PBRC are useful instruments for measuring body image. Several versions of the BIA are available for different populations.

Body Image Assessment (BIA - ORIGINAL)

The BIA was developed as a figural stimulus method for assessing body image disturbances associated with eating disorders in women. It measures an individual’s estimate of actual body size and an estimate of the individual’s ideal body size. The discrepancy between current body size and ideal body size is a reliable and validated measure of dissatisfaction of body size. The BIA uses silhouettes of nine female figures ranging from very thin to overweight as test stimuli. Instructions for use are included.

Body Image Assessment for Obesity (BIA-O)

The BIA-O is a validated body image assessment tool for obesity. It is an expansion of the original BIA and can be used with obese men and women. The BIA-O uses silhouettes for obese men and women ranging from very thin to very obese as test stimuli. Instructions for use and validating publications are included.

Body Image Assessment for Pre-Adolescents (BIA-P)

The BIA-P is a reliable and validated expansion of the original BIA and was developed for use with preadolescent boys and girls (ages 10 – 13).The BIA-P uses four sets of body image silhouettes, ranging from very thin to obese, which correspond to male and female preadolescents. Instructions for use are included.

Body Image Assessment for Children (BIA-C)

The BIA-C is a reliable and validated expansion of the original BIA and was developed for use with male and female children (ages 8 – 12). The BIA-C uses four sets of body image silhouettes, ranging from very thin to obese, which correspond to male and female children. Instructions for use are included.
