Healthy Growth Abbreviated Pilot Study

This novel intervention, delivered to mothers primarily through private Facebook groups,
will promote behavior change through peer and self-modeling photo/video activities.

In this study, we will implement an abbreviated 2-month version of the intervention with a
single peer group of up to 10 mothers. We will assess the feasibility and acceptability of
both the intervention and our intended outcome measures, in preparation for a randomized
pilot trial of the full intervention.
