PHE 425 Module 4 Discussion Example

Reviewed by Delia Ravenscroft, MSN, RN

This PHE 425 Module 4 Discussion sample shows how to choose a behavior theory for a program plan. It was written for SNHU PHE 425 (PHE-425), whose fourth module has BS Public Health learners select a theory and defend the choice. The program brings dental sealants into elementary schools in a composite county on Tennessee's Cumberland Plateau, where fewer than four in ten consent forms came back in a pilot. The post starts by asking whose behavior has to change, which turns out to be parents rather than children, then compares the health belief model, social cognitive theory and the ecological model. It chooses the health belief model, adds self-efficacy and asks classmates how they decided whose behavior their theory should explain.

Module Four Discussion

The Theory Has to Explain a Signature

Before picking a theory, I had to answer a simpler question: whose behavior does the sealant program depend on? Not the children's. A seven-year-old does not decide whether to be sealed. The program depends on a parent reading a form, signing it and sending it back. Last year's pilot got 38% of forms returned, so that signature is the behavior my theory has to explain.

I considered three options. The health belief model explains action through perceived susceptibility and severity, perceived benefits and barriers and cues to action (Janz & Becker, 1984). Our listening sessions matched it closely. Some parents doubted that back teeth in young children matter, which is susceptibility and severity. Several were wary of forms asking for Medicaid numbers, which is a barrier. Many said they never saw the form at all, which is a missing cue.

In social cognitive theory, people, their actions and their surroundings shape one another, and confidence in one's own ability sits at the core (Bandura, 2004). It fits programs that build a skill over time, such as cooking or exercise. Signing a form is a single act, so most of the theory's power goes unused, although self-efficacy matters for parents who find forms hard to read.

The ecological model spreads its view across five layers, from the person and family through schools and the community to policy (McLeroy et al., 1988). It is the right lens for the program as a whole, because the school, the nurse and Medicaid billing all shape what happens. Still, it gives me no wording for the form itself.

So I chose the health belief model for the consent decision, with self-efficacy added, as later versions of the model do. That points to concrete steps: a form that explains why molars matter, no insurance number required to say yes, a text message from the school as a cue and a phone number for the nurse. Each step traces to one construct.

For classmates: did you find that the person whose behavior your program depends on was different from the person it is meant to help?

What the PHE 425 Module 4 instructions ask for

For Module Four, PHE 425 asks you to choose a behavior change theory for your program and defend the choice. A one-page post resting on two or three APA 7 sources is typical, followed by peer replies. Begin by naming the specific behavior and the person whose decision the program depends on. Compare at least two or three theories, describing their key constructs and testing each against what you know about your population. Choose one, explain why it fits better than the others and show how its constructs point to concrete program strategies. Note where another theory or model still adds value, then pose a question for your classmates to answer.

How this PHE 425 Module 4 discussion example is built

In this PHE 425 post, the student first decides that a rural Tennessee county's sealant program depends on parents signing consent forms, returned at 38% in a pilot. Janz and Becker's health belief model fits parents' doubts about back teeth, wariness of insurance questions and forms never seen. Bandura's social cognitive theory suits skills built over time, so only self-efficacy is borrowed. McLeroy and colleagues' ecological model frames the whole program but not the form. The chosen theory leads to a clearer form, no insurance number to say yes, a school text as a cue and the nurse's number. A question about decision makers closes the post. Each strategy maps to a construct.

Where the PHE 425 Module 4 rubric puts the points

Graders of the PHE 425 theory discussion usually look for a clearly defined behavior and decision maker, accurate descriptions of several theories, a comparison grounded in evidence about the population, a reasoned choice and a link from constructs to strategies. Posts that score highest show how the theory changes what the program will actually do. Graders mark down posts that pick a theory because it is familiar or list constructs without applying them. Correct APA 7 citations, a concise length and a question that invites real exchange complete stronger posts, and thoughtful replies that test a classmate's choice earn credit. Brief posts that stay specific score best. Accurate construct names matter.

PHE 425 Module 4 help: the mistakes that cost points

Theory posts for PHE 425 often lose points by choosing a theory before defining the behavior, describing constructs from the textbook without local evidence or naming a theory that never shapes the program. If your program targets a different behavior, such as quitting vaping, getting screened or taking medication, send the prompt and what you know about the people involved, and the post will compare theories against that evidence and show how the chosen one shapes the strategies. Notes from interviews or surveys make the comparison stronger. Our PHE 425 theory posts end with strategies a reader could put into practice. Replies can be drafted too.

Where can I find a free PHE 425 Module 4 Discussion sample?

This page carries the full PHE 425 Module 4 post choosing the health belief model to explain parents' consent decisions for a school sealant program.

How do you choose a behavior change theory for a program?

Define the behavior and who decides it, then test each theory's constructs against evidence about that population and pick the best fit.

Which constructs make up the health belief model?

Perceived susceptibility, severity, benefits and barriers, cues to action and, in later versions, self-efficacy.

When is social cognitive theory a better fit?

When a program builds skills and confidence over time through practice, modeling and support, such as exercise or diet change.

Can a program use more than one theory?

Yes, many programs use one theory for an individual decision and a broader model, such as the ecological model, for the overall design.
