DQ 2 : Provide a short description of the intervention you developed and how you plan on evaluating it.
Four questions, and the last two are about what happens after the results arrive. Next steps and use of the data are where the marks sit and where most posts stop.

The intervention, its evaluation, and what happens after
Describe the intervention in a form somebody could act on: the population, what is delivered, by whom, how often, over what period, and the outcome it targets. Then set out the evaluation plan with the same discipline — the indicator, the data source, when it is collected, and what comparison makes the number interpretable. Because you are unlikely to have a control group, say whether your comparison is a baseline, a comparison community or a trend, and name the threat that comparison leaves open. Include process measures alongside outcome ones, since a null result without delivery data cannot be interpreted at all, and at the close of a course this is the point where the difference between the intervention you designed and the intervention that ran becomes the most useful thing you know. Say what the intervention was meant to change and in whom, so the evaluation section has something to attach to.
Then answer the two questions that carry the marks. Next steps depend on what the evaluation shows, so state them conditionally rather than as a plan: if the outcome moved and fidelity was good, the step is to sustain and spread, which means embedding delivery into someone's job description rather than into a project. If the outcome did not move but fidelity was poor, the intervention has not been tested and the step is to fix delivery and re-run. If fidelity was good and nothing moved, the honest step is to stop and say so publicly, which is the hardest and most valuable of the three. As for what you can do with the data: report it back to the community that produced it, use it to argue for funding, feed it into a needs assessment, and use it as a baseline for whatever comes next.
Likely learning objectives

PHN 652 Topic 8 DQ 2 DQ 2 : Provide a short description of the intervention you developed and how you plan on evaluating it. Through this course, you have participated in the public health nursing model of planning, implementing, and evaluating a population-based intervention. Provide a short description of the intervention you developed and how you plan on evaluating it. What would your next steps be after the evaluation? What can you do with your evaluation data?
Turn the brief into deliverables
- 01The intervention: population, content, deliverer, dose, duration, outcome.
- 02An indicator, a data source and a collection point.
- 03A comparison strategy and the threat it leaves open.
- 04Conditional next steps for at least three result patterns.
- 05Uses for the data with an audience named for each.
Description, evaluation plan, then the use of the data
The intervention, operationally
State population, content, deliverer, dose and duration.
What the assessor is likely looking for
Enough detail for another nurse to deliver it.
The evaluation plan
Name indicator, source, timing and comparison.
What the assessor is likely looking for
A comparison with its validity threat identified.
Process alongside outcome
Include fidelity, reach and dose delivered.
What the assessor is likely looking for
A measure that distinguishes non-delivery from failure.
Next steps, conditionally
Set out sustain, fix-and-re-run, and stop branches.
What the assessor is likely looking for
The stop branch, stated without hedging.
What the data is for
Name uses and audiences: community, funder, needs assessment, evidence base.
What the assessor is likely looking for
An audience attached to each use.

Review before submission
Common mistakes
- Describing the intervention at length and treating the last two questions as a conclusion.
- Giving unconditional next steps that assume the intervention worked.
- Omitting process measures, leaving a null result uninterpretable.
- Listing uses for the data without saying who receives it.
Submission checklist
- Could someone else deliver your intervention from the description?
- Is there a comparison, and is its weakness named?
- Are next steps conditional on the result?
- Have you included the stop-and-say-so case?
- Does each use of the data have an audience?
