Youth-adult relationships exist on a continuum from adult-led to youth-led collaborations. However, research suggests that quality youth-adult partnerships, which fall in the middle of this continuum, directly contribute to positive youth development. Given this, the current study evaluated the impact of a 4-H Youth Development program, using youth-adult partnerships and a teens as teachers program model, on positive youth development outcomes of participating youth. Qualitative data were collected from 29 youth to evaluate the 4-H Food Smart Families program presented by Washington State University Youth Advocates for Health (YA4-H!). Data analysis identified themes related to the benefits and challenges of the youth-adult partnership and skills gained from being a teen teacher. When looking at results from a positive youth development perspective, it is evident the youth who participated in youth-adult partnerships and as teen teachers experienced beneficial outcomes. Qualitative codes clearly aligned with 4-H Essential Elements of belonging, mastery, independence, and generosity, indicating positive youth development had occurred despite real-world implementation challenges. Based on our experience and lessons learned, we conclude with suggestions for successful implementation of a youth-adult partnership.
