Week 3 moves the explanation outward from the individual to the people and settings around them. The organizing idea is reciprocal determinism: person, behavior and environment shape each other continuously, so a plan can work on any of the three. The constructs that do the most work in written assignments are self-efficacy, observational learning, outcome expectations, reinforcement and the difference between what people think others do and what others actually do. 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 3 asks for
New parents leaving a maternity unit are told how an infant should be placed to sleep, they can repeat the advice accurately at the two-week visit, and a proportion of them are doing something different by the two-month visit. Nothing in that sequence is explained by a knowledge deficit. What changed between the two visits is that the family went home into a household where a grandmother who raised four children advises otherwise, where the baby settles better in a position the parents were told to avoid, and where the immediate reinforcement of a sleeping infant arrives every night while the risk being prevented is invisible and probabilistic. That gap between knowing and doing, and the social and environmental machinery inside it, is what this stage is for.
The theory gives you named handles on that machinery. Self-efficacy is confidence in performing this specific behavior under real conditions, and it is the construct most consistently associated with actually doing things; it is raised chiefly by successfully performing a small version of the behavior, secondarily by watching someone similar succeed, and only weakly by encouragement. Observational learning says that behavior is acquired by watching models whose similarity to the observer matters more than their authority. Outcome expectations are what a person believes will follow from acting, which is not the same as what the evidence says will follow. Reinforcement covers what actually happens after the behavior, including the immediate consequences that so often run against the recommended action.
Interpersonal influence is the companion material. Social support divides usefully into emotional, informational, instrumental and appraisal support, and those four call for completely different activities. Social norms divide into what people believe others do and what people believe others approve of, and the two frequently diverge. A perceived norm can be measurably wrong, which is the basis of an entire family of corrective interventions, and checking whether your audience's perception matches reality is a specific, evidenced move rather than a generic one.
Expect a written application in which these constructs have to produce activities rather than paragraphs. The strongest submissions at this stage name a model the audience would recognize as similar to themselves, describe a mastery experience small enough to succeed at, and identify what currently reinforces the behavior they are trying to displace.
The MPH-505 Week 3 method, step by step
Six moves for turning social learning constructs into a plan.
-
Locate the knowing-doing gap and describe it
Show, with evidence, that your audience already knows what to do. If knowledge is genuinely absent, this material is the wrong tool and the honest paper says so.
-
Break the behavior into a first step small enough to succeed
Self-efficacy grows from performance, so design an action the audience can complete on the first attempt, then a second slightly harder one. A plan with no graded sequence has no efficacy strategy.
-
Choose models on similarity, not status
Name who the audience would see themselves in: same life stage, same constraints, same language, same neighbourhood. A credentialed expert demonstrating an easy version of the behavior is the weakest model available.
-
Write the outcome expectations your audience actually holds
Including the negative ones and the socially awkward ones, sourced from formative work rather than assumed. A plan that only addresses the health outcome will lose to the expectation nobody wrote down.
-
Audit what currently reinforces the competing behavior
Immediate, reliable and near-term consequences beat delayed, probabilistic ones. Say what the audience gets right now from the alternative, then find something the recommended behavior can deliver quickly.
-
Check the perceived norm against the actual one
If most people already do the behavior and your audience believes they do not, correcting the perception with real local data is a defensible intervention. If the perception is accurate, that route is closed and you must say so.
Build the social learning section and budget the words
Our frame for this stage's application paper, sized for roughly 1,200 to 1,500 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 |
|---|---|---|
| The gap, evidenced | What the audience knows, what they do, and the size of the distance between the two with a source. | 160 to 200 |
| Efficacy strategy | The graded sequence of attempts, the setting each happens in, and who provides feedback after each one. | 250 to 300 |
| Models and modelling | Who demonstrates, on what similarity criterion, through what medium, and showing which part of the behavior. | 220 to 270 |
| Outcome expectations | Held expectations, positive and negative, and which message addresses which, with formative evidence behind each. | 220 to 270 |
| Reinforcement audit | What follows the competing behavior now, what will follow the target behavior, and how soon. | 200 to 250 |
| Norms, perceived and actual | The perception, the local reality if you can source it, and whether correction is available as a strategy. | 180 to 220 |
Evidence craft for social and environmental constructs
Use a validated efficacy scale rather than inventing one. Self-efficacy is measured behavior by behavior, and published scales exist for a wide range of actions. Naming the scale you would use, with its source, converts a vague intention to measure confidence into a scoreable evaluation plan.
Say which type of support an activity provides. Emotional, informational, instrumental and appraisal support are different interventions with different staffing implications. A plan promising increased social support without saying which type is a plan nobody could implement.
Source your norm claim, or drop it. Asserting that a behavior is normative in a community without data is the fastest way to lose an evidence row here, and a corrective norms message built on an unverified norm can also backfire by telling people the undesirable behavior is common.
Report peer intervention effects with their design. Peer-delivered programmes are widely studied and results vary substantially by how peers were selected, trained and supervised. Name those details when you cite an effect, because they are the difference between a result you can expect to reproduce and one you cannot.
Five mistakes that cost points in this week's territory
- Self-efficacy treated as encouragement. Confidence is built by successful performance of a graded task, not by being told you can do it, and the plan has to show the task.
- Models chosen for authority. A clinician demonstrating a behavior to an audience with different constraints produces little observational learning.
- Reinforcement ignored entirely. Plans that never ask what the audience currently gets from the competing behavior are working against an incentive they never identified.
- Norms asserted rather than measured. An unsourced claim about what a community does is both an evidence failure and a risk of normalizing the wrong thing.
- Environment left untouched. The theory explicitly includes the setting, so a plan that only works on the person has used a third of the model.
Before you submit
- The knowing-doing gap is demonstrated with evidence rather than assumed
- A graded sequence of attempts is described, starting with one that will succeed
- Models are chosen on a stated similarity criterion
- Negative outcome expectations appear alongside the positive ones
- The reinforcement audit names what the competing behavior currently delivers
- Any norm claim carries a source, or is labelled as unknown
