The conversion of a practice-based lifestyle enhancement program into a formalized, testable program: From Texercise Classic to Texercise Select

Little is known about the structure, content, and benefits of practice-based or grass roots health programs that have been widely delivered by a variety of community organizations and stakeholders.This perspective will document the natural history ofTexercise Classic, a state-endorsed but previously untested lifestyle health promotion program. It will: (1) discussTexercise Classic's participant reach and adoption over time; (2) describe the rationale and processes employed to formalize Texercise Classic into a more structured program known asTexercise Select ; (3) outline the essential elements and activities included inTexercise Select and contrast them with those included in Texercise Classic; and (4) highlight key components for uniform facilitator training. The discussion will refiect upon the evolution of Texercise, compare and contrast the benefits and challenges of each program, and review the "next steps" for Texercise Select. In contrasting Texercise Classic and Select, it is important to understand the benefits and challenges of both programs. Preliminary results indicate that Texercise Select is effective, yet its ability to sustain the same reach as Texercise Classic remains unknown and an area for future study.
