Translation Model

The Center TRT translation efforts support the CDC's Division of Nutrition, Physical Activity and Obesity by providing practitioners with the best available evidence on preventing and controlling obesity. This includes providing the guidance, tools, and, in some cases, training to help practitioners identify WHAT to do and HOW to do it.  

A Four-Phase Translation Model

The Center TRT investigators and staff, in collaboration with our National Advisory Board and CDC partners, developed a four-phase framework to guide translation activities.


Center for Training and Research Translation



Phase 1:   Evidence Identification and Review

Existing evidence reviews are used to identify broad, evidence-based strategies that offer the best options available for planning effective interventions.   Strategies presented on the Center TRT website can be used individually or grouped in various combinations to form interventions.

Center TRT identifies for review behavioral, organizational, environmental and policy-level interventions. Recommendations come from CDC and other experts, practitioners in the field, and from published scientific literature.  Interventions are reviewed against an established set of criteria for evidence of the:

  1. methods used to test and/or develop and evaluate the intervention,
  2. potential for public health impact based on the five dimensions of the RE-AIM framework, and
  3. readiness for dissemination.  

The evidence review process determines whether or not the intervention meets criteria in one of three intervention categories: research-tested, practice-tested, or emerging.   Interventions that meet criteria move to Phase 2.

Phase 2:   Intervention Abstraction

Following intervention review, Center TRT staff, in collaboration with the intervention developer, abstract and format practice-relevant information into an intervention "template."   The template provides practitioners with an overview of the intervention, including its potential for public health impact defined by Reach, Effectiveness, Adoption, Implementation and Maintenance (www.re-aim.org);  a summary of research findings or evaluation outcomes; the evidence-base for strategies used to support the intervention; the core elements of the intervention; a step-by-step guide to implementation; resources needed to implement the intervention; and sources of additional information, technical assistance and training.

Phase 3:   Dissemination

Intervention templates and accompanying materials and tools that support implementation of interventions are disseminated through this website.   In addition, Center TRT training courses, web-based trainings, and webinars  (live and archived) provide instruction on intervention implementation and use of intervention materials.  

Phase 4:   Research/Practice Integration

A feedback loop that promotes the integration of research into practice and practice into research completes the model.   Training, technical assistance, state-to-state mentoring, ongoing research and evaluation result in the adaptation, reinvention, and refinement of interventions, which bring the model full circle and promote the evolution of evidence-based public health practice.
