Objectives: To document implementation challenges and opportunities associated with small store interventions.
Methods: Case study analysis of small store interventions conducted in 4 regions of the US. We systematically generated matrices to compare and contrast lessons learned to advance implementation science.
Results: Seven thematic areas were identified including: establishing relationships with stores, store owner and customer relationships, selection of intervention approaches, stocking healthier foods, evaluation, maintenance of changes, and dissemination.
Conclusions: This information provides guidance to researchers and practitioners wishing to design, implement, and evaluate small store interventions.
