Body image is an important parameter of body satisfaction and needs to be evaluated with instruments developed and validated for a specific population. The aim of this study was to develop and validate a scale to assess body image in Brazilian women. A scale consisting of 11 silhouettes was prepared. Content validation was performed by seven experts from different health areas. To assess repeatability (two consecutive assessments) and reproducibility (reassessment after one week), an intentional sample stratified into four groups according to the characterization of Brazilian women regarding nutritional status was selected. Participants were 125 women aged 18-55 years and body mass index (BMI) between 18.5 and 38.6 kg/m2. The Kappa coefficient (k) was used to assess repeatability and reproducibility, considering the isolated responses of the current body, ideal body and the difference between them, assumed as satisfactory when k≥0.6. For all trials, α=0.05. During the content validation phase, the instrument developed was changed following the evaluators’ suggestions and it was considered very suitable by six of seven evaluators. The Kappa coefficient was good in isolated issues and in the difference between them in both repeatability and reproducibility. The Body Image Scale was considered a valid content, with good repeatability and reproducibility. Considering the instrument as low cost and of rapid implementation/evaluation, it may be used to evaluate the body image of Brazilian women with BMI between 18.5 and 38.6 kg/m2, in different contexts.
