Week 4 introduces the models that treat readiness as something that moves, and the communication practice that follows from them: matching the message to where the person currently is rather than sending everyone the same appeal. The writing task is to show a message set that differs by stage, with a defensible way of assessing stage, and an honest account of the criticisms these models attract. Your section may print this as MPH 505 or MPH505; 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 MPH-505 Week 4 asks for
A pediatric asthma clinic sends the same tobacco cessation leaflet home with every family whose child has had an exacerbation. Among the parents receiving it are a father who has never considered stopping and resents the implication, a mother who has thought about it for months without acting, a father who has set a date for next month, and a mother who stopped eleven weeks ago and is finding evenings hard. One leaflet is at best useful to one of them and is actively counterproductive for at least one other. The stage-matched alternative sends four different messages, and building that set is the assignment.
The dominant framework here describes movement through a sequence: not considering the change, considering it without commitment, preparing and taking small steps, acting, and maintaining the change over time, with relapse treated as a normal event within the process rather than as failure. Two other elements travel with it. Decisional balance describes the shifting weight of perceived pros against cons, and the pros typically have to rise before movement occurs. Processes of change describe what people actually do to move, and they divide into the ones that work early, which are largely cognitive and emotional, and the ones that work later, which are largely behavioral and environmental. That division is the practical payoff: telling someone in the earliest stage to remove triggers from the house is asking for an action they have not agreed to take.
Tailoring is the communication practice built on this. It is not the same as targeting. Targeting designs a message for a defined segment and sends everyone in that segment the same thing. Tailoring uses an individual assessment to generate content specific to that person, which is why it needs a data collection step and a decision rule, and why the operational cost is a real part of your plan rather than a footnote. Papers that promise tailored messaging without specifying what would be asked, when, and what rule maps answers to content have described an aspiration.
You are also expected to engage the criticism. Stage models have been contested on whether the stages are genuine qualitative categories or arbitrary cuts on a continuum, and reviews of stage-matched interventions report mixed effects. A paper that presents the model as settled science reads as uncritical; one that names the debate, cites both sides, and explains why the staged approach is still the right call for this particular behavior reads as graduate work.
The MPH-505 Week 4 method, step by step
Six moves for writing a stage-matched communication set.
-
Write the staging question you would actually ask
One or two items with clear cut points, phrased in ordinary language, delivered somewhere the audience already is. Without a staging instrument there is no tailoring, only a claim about one.
-
Estimate the distribution across stages before designing
Published studies in comparable populations give you rough proportions. If most of your audience sits in the earliest stage, most of your effort and budget belongs there rather than spread evenly across five.
-
Draft one real message per stage
Actual sentences, not descriptions of themes. The early-stage message raises personal relevance without demanding a decision; the later ones supply skills, planning tools and relapse handling.
-
Match the change process to the stage
Cognitive and emotional processes early, behavioral and environmental processes later. Naming the process each message is intended to activate is what converts a message set into a theory application.
-
Design the relapse response before launch
Return to an earlier stage is expected in these models, so the plan needs a re-entry path that does not read as reprimand. Its absence is the most visible gap in student plans at this stage.
-
State the operational cost of tailoring
Who collects the staging data, where it lives, who maintains the message library, and what happens when someone does not answer. Tailoring that nobody can run is not a plan.
Assemble the stage-matched set and budget the words
Our frame for this stage's paper, sized for roughly 1,300 to 1,600 words. It is our own outline rather than anything the university issues, and your week's scoring guide outranks it wherever the two disagree.
| Section | What belongs in it | Word target |
|---|---|---|
| Why staging fits this behavior | The case that readiness varies meaningfully here, with evidence, and what a one-message approach would waste. | 170 to 210 |
| The staging instrument | The items, the cut points, the delivery moment, and what you will do with non-response. | 200 to 250 |
| Expected distribution | Estimated proportions by stage from comparable published populations, with the implication for effort allocation. | 150 to 190 |
| The message set | One drafted message per stage, each labelled with the change process it activates. | 350 to 420 |
| Decisional balance handling | The pros and cons your audience reports, and which message shifts which side of the balance. | 200 to 250 |
| Relapse and re-entry | The trigger for re-engagement, the message that carries it, and the tone rule it follows. | 150 to 190 |
| Critique and justification | The published criticism of stage models and your reasoned defence of using one here. | 170 to 210 |
Evidence craft for stage-based work
Cite reviews, not only single trials. The effectiveness of stage-matched interventions varies by behavior and by how well the matching was implemented, so a systematic review or meta-analysis gives a truer picture than the one favourable trial that is easiest to find.
Report stage distributions with their population. The share of an audience in each stage differs enormously between behaviors and settings, so a figure borrowed from another population needs its source, its year and a sentence on why it is a reasonable proxy for yours.
Name the tailoring variables explicitly. Stage alone, stage plus barriers, stage plus decisional balance: these are different levels of tailoring with different data requirements and different evidence. Say which you are proposing.
Handle the criticism with sources on both sides. Cite a substantive critique of stage models and a defence or a supportive review, then state your own position. An acknowledgement of debate with only one side cited is not engagement.
Five mistakes that cost points in this week's territory
- Naming stages without staging anyone. If nothing in the plan assesses where a person is, the stage model has been described rather than used.
- The same message with different headings. Five near-identical paragraphs relabelled by stage is the commonest way this assignment is faked, and it is easy to see.
- Action messages sent to the earliest stage. Instructions to prepare and act, delivered to people who have not decided anything, produce resistance rather than movement.
- Relapse treated as failure. The model treats return as expected, so a plan with no re-entry path contradicts the theory it claims to apply.
- Tailoring promised with no mechanism. No assessment, no rule, no library and no owner means no tailoring, however often the word appears.
Before you submit
- A staging instrument with items and cut points appears in the plan
- Each stage has a drafted message, not a described theme
- Each message is labelled with the change process it is meant to activate
- Early-stage content demands no commitment the audience has not made
- A relapse re-entry path exists with a stated tone rule
- The published critique of stage models is cited and answered
