Table 1 A Suggested Typology of Useful Evidence

Intervention

Describe the theory behind the EBI and the core components and program logic (intended and actual). Determine appropriate adaptations to the context.

Analyze the impact of core components and test the pathways outlined in the program logic.

Design to test variation in content and dose.

Implementation strategies

Describe the type and function of the implementation strategies (planned and actual).

Analyze the impact of implementation strategies on outcomes.

Experiment with implementation strategies and tailor them to the context.

Context

Describe the salient features of the context and why they are important to the outcomes (moderators).

Analyze how the contextual factors moderate outcomes (barriers and facilitators).

Design to test matching interventions to known moderators.

Design to test the intervention in clinical practice and in community settings.

Outcome

Measure and report (1) all outcomes outlined in the program logic model, (2) the implementation outcomes, and (3) the value that end users place on the outcomes. Monitor unintended consequences.

Analyze how the intervention, implementation strategies, and context interact to produce outcomes.

Study the trends by using time-series data and integrated data systems, which can be used to improve care at the single-patient and group/system levels.
