Health Content Foundations: Behavior-Change Theory and the National Health Education Standards
This section samples the foundational content and the theory base that justifies health instruction. Items rarely ask you to recite a definition; they describe a student, a classroom, or a program and ask you to name the construct or the standard being addressed. Learn each theory by its distinguishing features, not its founder.
Behavior-change theories to distinguish
- Health Belief Model: perceived susceptibility, perceived severity, perceived benefits, perceived barriers, self-efficacy, and cues to action. Strong at explaining one-time uptake such as screening or vaccination; weak at predicting sustained habits.
- Transtheoretical (Stages of Change) Model: precontemplation, contemplation, preparation, action, maintenance, with processes of change, decisional balance, and self-efficacy. Intervention differs by stage - consciousness raising for precontemplation, stimulus control and counterconditioning for action.
- Social Cognitive Theory: reciprocal determinism, observational learning, behavioral capability, self-efficacy, outcome expectations, reinforcement.
- Theory of Planned Behavior: attitude, subjective norms, and perceived behavioral control feed intention, which predicts behavior.
National Health Education Standards
Standard 1 is functional health knowledge. Standards 2–8 are skills: analyzing influences, accessing valid information, interpersonal communication, decision making, goal setting, practicing health-enhancing behaviors, and advocacy. Note the trap: knowledge alone is Standard 1; a pretest on refusal skills is not.
Worked example
A student says, "My grandfather smoked and lived to 90, so smoking is not really dangerous for me." The construct is perceived susceptibility (Health Belief Model) - the student discounts personal risk regardless of how severe he considers smoking. The instructional response is accurate local prevalence and personal-risk data, not a lecture on disease severity, which he already accepts.
Traps that cost marks
Treating self-efficacy (SCT) as identical to perceived behavioral control (TPB). Placing a student who has only made a quit plan in "action" - that is preparation. Describing a health class as skill-based because it uses a worksheet of facts.
Key rules
Match the theory to the described behavior. Name the construct, then justify it from the stem's own words.
