How You Can Use Insufficient Evidence Findings

Develop research proposals and funding announcements based on insufficient evidence findings of the Community Preventive Services Task Force (CPSTF)

Some Ways You Can Use CPSTF Insufficient Evidence Findings

Discover Proposal Ideas

You can develop research proposals and funding announcements that address the reasons behind an insufficient evidence finding, such as too few studies or inconsistent results, that could serve to strengthen the evidence base. Proposed studies could

  • focus on research studies or program evaluations of interventions (e.g., programs, services, and policies) that have a small number of studies demonstrating effectiveness but still need more evaluations, or
  • reproduce an intervention to generate more evidence that could become part of the body of evidence that CPSTF reviews when deciding whether to recommend the intervention, or
  • address factors such as study design, measurement of outcomes, or delivery of the intervention to strengthen the evidence base.

Insufficient Evidence Findings

CPSTF uses the results of systematic reviews of interventions to issue findings based on the strength of the evidence (effectiveness and economic).

A finding of insufficient evidence means that not enough evidence exists or there is inconsistent evidence. As a result, the CPSTF cannot recommend for or against use of an intervention. It does not mean the intervention does not work.

Strengthen Your Proposal

You can use information from the Task Force Findings and Rationale Statement (TFFRS) for an insufficient evidence finding to strengthen your proposal. The TFFRS provides the official CPSTF language, including the intervention definition, context and results of the systematic review, considerations for implementation, and evidence gaps. This information can be helpful for developing parts of a research proposal or funding opportunity announcement. You can use the information to

  • guide development of the Background section, or
  • develop a conceptual framework, or
  • justify the purpose or need for a program and show public health relevance.

Use of Insufficient Evidence Findings Can Lead to Public Health Impact

Developing research & funding announcements based on insufficient evidence findings; Supports new studies & public health programs; Leads to public health benefits & stronger evidence base; Leads to more CPSTF recommendations on interventions that work in public health practice
