title: Initial evidence of the reliability and validity of a three-dimensional body rating scale for the congenitally blind.
abstract: Research on body dissatisfaction has grown significantly. However, valid and reliable instruments for measuring body dissatisfaction in the congenitally blind have yet to be developed. In three studies, we report on development, test-retest reliability, and concurrent and content validity of the Three-dimensional Body Rating Scale (3BRS) for the congenitally blind. In Study 1, 58 people with congenital blindness (28 women, 30 men; M age = 36.7, SD = 13.1) numerically ordered models of the 3BRS and models of the Two-dimensional Body Rating Scale (2BRS), from very thin to the very fat. In Study 2, the construct validity and reliability of the 38RS was assessed. The same participants from Study 1 chose the 3BRS model that represented their ideal body and the 3BRS model that represented their actual body. Two weeks later, a re-test was done. In Study 3, 16 experts judged the content validity of the 3BRS. The psychometric properties of the 3BRS, its utility, and its limitations are discussed along with considerations for future research.
