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.

OBJECTIVE: To assess the method and time to stand from supine and the time to run 10 m for normal young children. STUDY DESIGN: Three hundred twenty-one normal children aged 2.8-7.8 years were recruited from primary schools. After standardization, each test was carried out twice, timed, and videoed. The influence of age, sex, height, weight, body mass index (BMI), and method of standing were analyzed. Charts for time to stand and running time were produced and assessment of reproducibility performed. RESULTS: For the time to stand from supine and the method used, there was a significant correlation with age. More than 50% of young children took >2 seconds. There was no significant association with BMI. Method of standing was associated with standing time in boys but not in girls. A Bland-Altman plot of standing times by 2 observers showed good reproducibility with no clinically significant difference. For the 10-m running test, there was a significant negative correlation with age, height, weight, and BMI. CONCLUSION: There is considerable variability in the method used and time taken to stand from supine in young children. These change with age, permitting the creation of charts showing age-related normal values.
