This project belongs to a research involving the development and validation of scales on food counseling and food and nutritional education (FNE) based on the Brazilian Dietary Guidelines (BDG). It aims to develop, validate and test the reproducibility of one of these scales, named GAB3. GAB3 will be validated and have its reproducibility tested for the observation of food counseling and FNE actions applied by health professionals from the primary health care system. The observer, a nutritionist expert in the BDG, will have to point out in GAB3 the dimensions of this publication that were considered by the health professional in the strategy and its adequacy as well. GAB3 will be developed and validated in 4 steps: (1) development of the items according to a defined theoretical reference; (2) content validation with experts to evaluate the adequacy of the items; (3) face validity with focus group involving possible users of the scale; (4) reproducibility test with 20 nutritionists experts in BDG and food counseling/FNE. In this analysis, the nutritionists will be invited to watch 5 videos, produced by this research, exhibiting simulated situations usually seen in the primary health care context. These experts will have to employ GAB3 to evaluate the application of BDG in the videos. After 1 month, they will be invited to a retest in order to evaluate the intra/inter-examiner reproducibility.
