Validation of the Family Health Behavior Scale for the Brazilian Population
Bibliographic record
Abstract
Abstract Background: It is well known that the family environment is associated with child health behavior and outcomes. However, there is a lack of available instruments to measure family health behaviors, even more so in languages other than English. The aim of the present study was to adapt and validate the Family Health Behavior Scale (FHBS) for Brazilian families.Methods: The FHBS was translated and culturally adapted for the Brazilian families. Psychometric properties (content validity, construct validity, and concurrent validity) and reliability (internal consistency, ceiling-floor effect, and test-retest) were evaluated in a sample of healthy community-dwelling children who were between 5 to 12 years old, of both sexes. Caregivers responded to the FHBS. Concurrent validity was assessed by comparing the FHBS scale with Body Mass Index (BMI) percentile, percent body fat, and physical activity level.Results: 272 children (54% girls) with a mean age of 7.9 years (SD = 2.0) and their caregivers were tested. Confirmatory analysis of the initial 4-factor structure (as proposed in the original English version of the questionnaire) suggested its performance was below acceptable. Exploratory factor analysis showed however an acceptable fit (Kaiser-Meyer-Olkin index = 0.79), and the factor loadings suggested a 7-factor model. Children who were considered obese (BMI percentile ≥ 97) had lower mean total FHBS scores than children who had a healthy weight or were overweight. Children who were classified as having a healthy fat percentage had higher FHBS scores than children classified as having an excessively high fat percentage. Children who were physically active had significantly higher total FHBS scores than children who were physically inactive. Cronbach's alpha was 0.81 and we noted acceptable values of the ceiling-floor effect. Test-retest analyses showed lower agreement and intraclass correlation coefficients than expected 0.63 (95% CI 0.41 to 0.78).Conclusion: The adapted Family Health Behavior Scale for the Brazilian population showed adequate psychometric properties.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
