Weighing the Health Belief Model against the Theory of Planned Behavior for parental HPV vaccination decisions, the PU508 Unit 2 example compares evidence for each and selects one. Searches like "pu 508 unit 2 assignment example", "pu508 unit 2 sample" and "pu508 unit 2 example" land here.
What a finished PU508 Unit 2 theory comparison paper looks like
About six pages, with a comparison table at the center. The introduction frames the behavior precisely: a parent consenting to the first dose for a child aged 11 or 12, in a state without a school requirement. Each model gets a short summary limited to its constructs and their proposed relationships. The comparison table then lines up those constructs against what studies of parental HPV decisions have found, showing that perceived susceptibility performs weakly because parents see infection as distant, while subjective norms and perceived behavioral control, including provider recommendation and clinic access, perform strongly. A discussion section weighs explanatory power, measurability and fit with the problem's level. The selection section chooses the Theory of Planned Behavior and states plainly what that choice gives up, including the cue-to-action construct the other model offers.
How a PU508 Unit 2 example is structured
Defining the behavior narrowly comes first, since both models predict specific actions and a vague behavior such as supporting vaccination would let either one appear to fit. Summaries follow and are kept brief, because the rubric in many sections rewards comparison over description and a long summary crowds it out. The table sits at the center so each construct is tested against the same body of evidence. The discussion then steps back to criteria that apply to both models, explanatory power, measurability and level of analysis, which keeps the comparison fair. The selection closes the paper and is written as a decision with costs, naming what the rejected model would have captured. That admission makes the choice look reasoned rather than arbitrary, and it sets up the construct mapping that later units in PU508 typically ask for.
The behavior, narrowly defined
Parental consent to the first HPV dose for a child of 11 or 12, in a state without a school mandate. The narrow definition makes each model's predictions testable.
Two models in brief
Constructs and proposed relationships only, one paragraph each. Neither summary recounts the model's history beyond a single citation to its original statement.
Constructs against evidence
A table pairing susceptibility, severity, benefits, barriers and cues with attitudes, subjective norms and perceived behavioral control, each row noting what studies of parents found.
Criteria for choosing
Explanatory power, how easily each construct can be measured, and whether the model operates at the level where the decision is actually made.
The choice and its cost
The Theory of Planned Behavior is selected, and the paper concedes that it lacks an explicit cue construct, the slot a clinician's recommendation might otherwise have occupied.
Where marks go in PU508 Unit 2
Three things usually decide a theory comparison grade: whether each model is represented accurately, whether the comparison is real, and whether the choice is justified. Constructs in the example appear as their authors defined them rather than as everyday words, which settles the first. The evidence table settles the second by testing both models against one population instead of describing them in parallel. Stated criteria and an admitted cost settle the third. Common deductions follow summaries that fill most of the paper, models compared in the abstract with no behavior attached, a model chosen because it is familiar, and claims that one framework is simply better rather than better for this problem. Several sections also deduct when constructs are listed without the proposed relationships that make them a model.

PU508 Unit 2 questions, answered
Why does the example reject the Health Belief Model?
Not because the model is weak in general, but because perceived susceptibility fits poorly when parents are deciding about an infection their child is unlikely to face for years. Studies of parental HPV decisions tend to find norms and provider recommendation carrying more weight. For a behavior like flu vaccination among older adults, the comparison might come out the other way.
Can the paper compare three models instead of two?
Some Unit 2 prompts allow or require three. The same structure applies, though the table grows and the discussion needs more discipline to stay comparative. Adding a third model tends to work best when it operates at a different level from the other two, so the comparison tests level as well as individual constructs.
Do I need to measure the constructs in this paper?
Not in full. The comparison draws on studies that measured them, citing how each construct was operationalized where that affects the evidence. Detailed measurement planning usually comes later in PU508, in a unit devoted to observing variables before and after an intervention. The example notes measurability as a criterion without designing instruments.
