Implementation Science, Ethics, and Program Evaluation
From Evidence to Durable Practice
Implementation as the Missing Link
Even highly effective psychological interventions fail if they are not adopted, delivered with fidelity, sustained, and scaled appropriately. Implementation science studies the conditions that determine whether evidence becomes routine practice.
Implementation Outcomes
Effectiveness vs Implementation
Effectiveness research
- Asks whether an intervention works
- Prioritizes outcome impact
- May occur under idealized conditions
Implementation research
- Asks how to make it work in practice
- Prioritizes feasibility, fidelity, and scale
- Often involves real stakeholders and systems
Ethical Priority
An intervention that is effective but inaccessible, inequitable, or harmful in context is not truly successful.
Which outcome reflects whether an intervention continues over time in real settings?
Sustainment refers to continued delivery and maintenance over time.
Correct answer: Sustainment
Why is fidelity important in program evaluation?
Without fidelity data, interpretation of results becomes much less precise.
Correct answer: Because it shows whether outcomes can be attributed to the intended intervention rather than ad hoc variation.
Evaluation and Ethics Checklist
-
1
Step 1: Specify intended outcomes, mechanisms, and stakeholders.
-
2
Step 2: Measure effectiveness, reach, and implementation outcomes.
-
3
Step 3: Track harms, inequities, and unintended consequences.
-
4
Step 4: Assess cost, feasibility, and sustainability.
-
5
Step 5: Use results to refine, scale, or discontinue the program.
Which practice best reflects ethical applied psychology?
Ethical practice requires attention to benefits, harms, and fairness in context.
Correct answer: Monitoring harms and equity alongside benefits
