MPH-507 Week 5 asks you to specify a program precisely enough that someone else could run it, and to justify each design choice from evidence rather than preference. The two graded skills are selection, meaning choosing an intervention with a documented effect on your determinant, and adaptation, meaning changing it for your setting while saying which elements you kept and why. Specification is what separates a plan from a description. Your section may print this as MPH 507 or MPH507; it is the same course. Chamberlain publishes no syllabi outside Canvas. The placement here is our teaching judgment from the course's catalog arc; your section's rubric decides what your week actually asks.
What a specified intervention lets someone do
A program manual written for replication is the standard this stage is aiming at, and reading one is instructive because of how little it leaves to interpretation. It states who delivers each component and what qualification they hold. It states how many sessions, how long each runs, over what period, in what setting and with what group size. It states what materials exist and in which languages. It states what a delivered session must contain to count as delivered, and what a facilitator may vary. A document written to that level can be costed, scheduled, staffed and evaluated. A document that says the program will provide education and support can do none of those things.
The territory of this stage is therefore specification and provenance together. Specification means dose in the program sense: number of contacts, duration, intensity and total exposure. Two programs with the same name and different doses are different interventions, and effect sizes in the literature attach to the dose that was delivered, not to the label. Provenance means naming where the intervention came from and what it achieved there, with the population and study design in front of the result.
Adaptation is the second half and it is normal professional practice rather than a compromise. Interventions developed in one population usually need changes for another: language, literacy level, delivery setting, cultural fit of examples, schedule, who delivers it, and how participants are recruited. The professional move is to distinguish core elements, meaning the components believed to produce the effect, from surface elements that can change freely. Adapting a core element is sometimes necessary and always worth flagging, because it weakens the claim that the original evidence transfers.
Deliverables at this stage are usually an intervention description with a justification, sometimes an implementation schedule or a staffing table, occasionally a comparison of two candidate interventions. Canvas posts do not reopen after submission, so verify what a cited program actually did before describing it publicly.
A method for designing something someone could run
Six moves that produce a specification with evidence behind it.
-
Search for interventions by determinant, not by topic
You are looking for what has moved the specific factor you targeted, in a population resembling yours. Searching by condition returns everything ever tried; searching by determinant and outcome returns the set your plan can actually build on.
-
Compare at least two candidates on the same dimensions
Effect achieved, population, dose, delivery requirements, cost order and fit with your setting. A choice made against alternatives is a design decision; a single option presented is an assumption, and the design row usually asks for the comparison.
-
Write the dose in numbers
Sessions, minutes, frequency, duration in weeks, group size and total contact time. This is the parameter that determines both effect and cost, and it is the one most often left out of student intervention sections entirely.
-
Name who delivers each component and what they need
Role, qualification, training required, supervision and time commitment. Staffing is nearly always the dominant cost in public health programs, so an intervention with unnamed deliverers cannot be costed in the feasibility section later.
-
Separate core elements from adaptable ones and say what you changed
List the components believed to produce the effect, then list your adaptations against them. For any core element you altered, state the reason and the risk that the original effect does not transfer.
-
Specify recruitment and retention as designed activities
How people learn the program exists, who refers them, what the eligibility check is, and what keeps them coming back. Programs fail at recruitment more often than at content, and a plan that assumes attendance has left out its largest risk.
A layout and word budget for an intervention section
Our frame for a specified intervention with its justification, sized for roughly 1,300 to 1,600 words. It is our own outline rather than anything the university issues, and your section's scoring guide outranks it wherever the two disagree. A component table listing activity, deliverer, dose, setting and materials carries this stage better than prose and will absorb around 250 words of the budget.
| Section | What belongs in it | Word target |
|---|---|---|
| Candidate comparison | Two or more evidence-based options rated on effect, population, dose, requirements and fit with your setting. | 230 to 280 |
| Selection rationale | The choice and the reasoning, tied back to the determinant you targeted and the objectives you committed to. | 170 to 210 |
| Component specification | Each activity with its deliverer, dose, setting, group size, materials and language requirements. | 290 to 350 |
| Adaptation record | Core elements retained, surface elements changed, and any core change with its reason and its risk. | 210 to 260 |
| Recruitment and retention | Referral routes, eligibility screening, enrollment target against the reachable population, and retention design. | 200 to 250 |
| Implementation sequence | What happens in what order, what has to be ready before launch, and where the schedule is tight. | 180 to 220 |
Evidence craft for intervention selection
Cite the intervention, not the idea. When you propose an activity, cite the study or program report where that activity was delivered and measured, and put the population and design in front of the result. A cluster randomized trial in a stated number of community clinics is a different warrant from a single-site pilot with pre and post measurement, and naming which one you have is what converts a preference into an evidence-based choice.
Report the effect in the units your objective uses. If your objective is expressed as a percentage-point change in coverage, find or convert the cited effect into the same terms rather than reporting a statistic your reader cannot map onto your target. Where conversion is not honest, say so and treat the transfer as qualitative.
Check whether the evidence population resembles yours on the things that matter. Age, language, baseline severity, insurance and service access, and the setting the program ran in all affect transferability. Say which differences exist between the study population and yours, and state the direction in which each would likely move the effect. That paragraph is short and it is what a design row rewards.
Use registries and review-level evidence where they exist, and name them. Compilations of evaluated programs and systematic reviews are stronger warrants than a single favorable study, and citing one lets a reader check your reasoning against a standard rather than against your search. Say which compilation, which version, and what its inclusion criteria were.
Five mistakes that cost points in this week's territory
- An activity list nobody could schedule. Provide education, offer support and increase awareness are categories rather than activities, and none of them can be costed or delivered.
- Dose omitted. Without sessions, duration and frequency, the intervention has no size, and the effect you cited attaches to a dose you have not committed to.
- Silent adaptation. Changing an evidence-based program without saying what changed lets the original evidence do work it can no longer support.
- One option presented as the only option. The design row typically asks why this intervention rather than another, and an unchallenged choice cannot answer it.
- Recruitment assumed. A plan that describes what happens in the room and never says how anyone gets there has skipped the most common cause of program failure.
Before you submit
- At least two candidate interventions are compared on the same dimensions
- Every cited effect carries its population, design and setting
- Dose is stated in sessions, minutes, frequency and duration
- Each component names who delivers it and what training they need
- Core and surface elements are distinguished and adaptations are recorded
- Recruitment, eligibility and retention are designed rather than assumed
