Distinct features of P & E interventions and recommended approaches to dissemination

Distinct features of P&E	Recommended Approaches to Dissemination
Evidence is emerging	1. Identify the best available evidence     • Evidence in support of effectiveness includes:         - Evidence of changes to environments         - Findings from expert consensus         - Findings from natural experiments     • Regularly update disseminated EBIs to remain current with latest evidence     • Build practitioners' skills to evaluate intervention impact
P&E change is complex	2.Prioritize EBI strategies over programs     • Consolidate existing lists of EBI strategies     • Disseminate consolidate strategies as a menu of options 3.Provide guidance on how to implement each strategy     • Disseminate alternative approaches to implementing each strategy     • Disseminate illustrations of each strategy in action and links to additional resources and tools 4.Incorporate stories from the field     • Disseminate the lessons practitioners experience implementing strategies     • Disseminate materials and tools that practitioners have developed
Vested interests may resist change Interventions may have high start-up costs Interventions require distinct skill sets	5.Provide tools, training and other resources to support the overall policy and environmental intervention process     • Disseminate tools to collect assessment and evaluation data     • Disseminate promotional materials and other resources to engage partners and counter resistance     • Provide training to build practitioners' competency to plan, implement and evaluate policy and environmental interventions 6.Integrate dissemination into practitioners' existing professional and social networks
