Summary

This pilot study tests a 10-week digital program called KnowHow for parents of children aged 3-5. The program includes a mobile app, virtual group discussions, and mailed materials covering mindful parenting, healthy eating, and physical activity. Researchers want to see if the program is easy to use and acceptable to families, not whether it changes health outcomes. About 60 families will participate.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
KnowHow Program (digital health intervention: mobile app, virtual groups, mailed materials)
What this could lead to
If successful, this could provide a scalable digital tool to help parents foster healthier habits in young children.
What could go wrong
This is a small pilot study (60 participants) focused on feasibility, not on proving health outcomes. Results may not apply to all families.
