Evidências de validade da Escala de Segurança Alimentar e Nutricional para adolescentes (ESANa)
Bibliographic record
Abstract
This study aimed to develop a valid and reliable scale for assessing food and nutritional insecurity, specifically in adolescents. The initial version of the scale consisted of two subscales: perception of food insecurity and perception of nutritional security. The items were submitted to content analysis (n = 4) by a group of food and nutrition security experts, and semantic analysis (n = 20) by a group of adolescents conveniently sampled from the target population. After adjustments, the final version of the scale was applied to adolescent students (n = 425) aged 12 to 18 years (m = 14.32±0.96; CV = 6.7%). A two-factor model was the most appropriate after performing exploratory factor analysis. The subscales showed modest values of the alpha coefficient (0.69 and 0.60, respectively). Daily consumption of fruits, vegetables and soft drinks was significantly associated with higher scores in the food and nutrition security perception scale. Therefore, it is recommended to combine food access-based items with other aspects related to attitudes and behaviors towards healthy eating in order to achieve a more accurate picture of adolescent's needs and better guide public policies.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
