This article describes the adaptation of a parent-focused evidence-based childhood obesity intervention program for implementation by county-based Extension educators in coordination with school district personnel in rural Pennsylvania. The Lifestyle Positive Parenting Program was designed and evaluated in Australia in clinical settings. Several minor and more serious adaptations, such as featured recipes and content of follow-up telephone calls, were made so that the program would be more appropriate for and appealing to target families. Conceptual issues regarding the adaptation of evidence-based programs are reviewed.
