The FNPA-PT screening tool demonstrates strong face and content validity for assessing obesogenic family environments in Portuguese well-child visits

The study translated and culturally adapted the Family Nutrition and Physical Activity (FNPA) screening tool for Portugal (FNPA-PT). Cognitive interviews with 10 parents of 5-year-old children showed 85% semantic equivalence and high acceptability, with minor revisions to three items.

Frequently Asked Questions

What is the FNPA-PT tool used for?▼

It is a culturally adapted screening tool for Portuguese primary care to assess family environments related to children's nutrition, physical activity, and obesity risk.

How was the FNPA-PT validated?▼

Through a seven-stage translation and adaptation process, followed by cognitive interviews with 10 parents to evaluate face and content validity.

What changes were made to the original FNPA for Portugal?▼

Minor linguistic and cultural adaptations were introduced, with revisions to three items concerning milk consumption, screen time, and sleep.

Is the FNPA-PT ready for clinical use?▼

The study supports its face and content validity, but further quantitative validation (e.g., reliability and predictive validity) is needed before widespread clinical implementation.
