RE-AIM domain	Outcomes	CFIR and additional implementation constructs
		Facilitator	Barrier	Mixed
Reach	• 124 individuals screened • 119 eligible for program • 88 eligible for research	• External change agents • Structural characteristics	• Time
Effectiveness	• 46.7% of participants met 5% weight loss goal (M ± SD: 5.2% ± 5.0%) • 56.7% met PA goal (M ± SD: 179 ± 122 min/week)	• Evidence strength & quality • Relative advantage • Compatibility • Organizational incentives & rewards • Goals & feedback • Participant receptivity	• Complexity
Adoption	• 12 out of 13 (92%) of Extension professionals trained immediately adopted	• Intervention source • Evidence strength & quality • Patient needs & resources • Implementation climate • Tension for change • Organizational incentives & rewards • Leadership engagement • Opinion leaders • Formally appointed internal implementation leaders • Champions	• Cost	• Structural Characteristics
Implementation	• Avg sessions implemented: 26 (range: 25–27)	• Evidence strength & quality • Relative advantage • Networks & communications • Implementation climate • Tension for change • Organizational incentives & rewards • Goals & feedback • Learning climate • Readiness for implementation • Leadership engagement • Access to knowledge & information • Individual identification with organization • Other personal attributes • Opinion leaders • Formally appointed internal implementation leaders • Champions • External change agents • Implementation strategy • Agent networks	• Complexity • Cost • Time • COVID	• Structural Characteristics
Maintenance	• 5 Extension professionals started 6 new DPP cohorts (virtual) • 1 Extension professional had started 1 new in-person DPP cohort • 2 Extension professionals planned for 2 new in-person cohort; these were implemented as planned after the conclusion of the study	• Evidence strength & quality • Relative advantage • Implementation climate • Compatibility • Organizational incentives & rewards • Learning climate • Leadership engagement • Access to knowledge & information • Individual stage of change • Formally appointed internal implementation leaders • Implementation strategy • Agent networks
