Tiers of Evidence: Criteria for Theory-based Interventions

Criteria for Tier III Interventions

  • Intervention is based on behavior change theory.
    • Determinants of change in the intervention logic model are based on behavior change theory.
  • Explanation of the intervention logic model is provided.
    • Intervention logic model demonstrates that the selected theoretical components are incorporated into the intervention content and activities in such a way that they will act upon the identified behavioral determinants and will likely produce the intended short-term & long-term behavior or biologic outcome(s).
  • Design of intervention and logic model is supported through formative research (e.g., needs assessment, focus groups, key informant interviews).
  • Process evaluation has been conducted during delivery of the intervention and demonstrates fidelity to the intervention logic model, provision of the intended services to the intended population, and acceptance by intervention participants.
  • Outcome monitoring has been conducted and demonstrates significant positive changes in at least one risk reduction relevant outcome or medication adherence relevant outcome at a follow-up beyond immediate post-intervention when compared to pre-intervention measures of the outcome(s).
  • No significant negative changes from pre- to post-intervention are observed in any risk reduction relevant outcome or medication adherence relevant outcome measured in the study.
