Health promotion is the process of enabling people to increase control over, and improve, their health. It targets well-being and healthy living for everyone, not just people at risk of a particular disease. Disease prevention is aimed at a specific condition and is usually described in levels:

Some texts add primordial prevention (preventing the risk factors themselves, such as keeping children from ever starting to smoke) and quaternary prevention (protecting people from unnecessary or harmful care).

Why theory matters. A health behavior theory explains why people act as they do and points to what a program should change. Programs grounded in theory are more likely to work than programs built on facts alone, because knowledge by itself rarely changes behavior.

Determinants of health. Individual behavior sits inside social, economic, and physical conditions. Healthy People 2030, the US national health promotion agenda from the Office of Disease Prevention and Health Promotion (HHS), frames these as social determinants of health in five domains: economic stability, education access and quality, health care access and quality, neighborhood and built environment, and social and community context. Its overarching goals are to help people live healthy, thriving lives free of preventable disease, injury, and premature death; eliminate health disparities, achieve health equity, and attain health literacy; create supportive social, economic, and physical environments; promote healthy development and behaviors at every life stage; and engage leadership and policy action across sectors.

International roots. The Ottawa Charter for Health Promotion (1986) set out five action areas that still shape US practice: build healthy public policy, create supportive environments, strengthen community action, develop personal skills, and reorient health services toward prevention and promotion.

Health Belief Model (HBM) — predicts whether a person will take a preventive action (screening, vaccination).

Modifying factors (age, culture, knowledge) influence these perceptions. Barriers are often the strongest single predictor, so removing them (mobile units, no-cost screening) is a high-yield strategy.

Transtheoretical Model (Stages of Change) — describes readiness to change.

Relapse is a return to an earlier stage, not failure. People usually cycle through the stages several times; the nurse normalizes the lapse, identifies triggers, and helps the person re-enter at contemplation or preparation.

Social Cognitive Theory (Bandura) — behavior, personal factors, and environment influence one another (reciprocal determinism). Key constructs: observational learning (modeling), outcome expectations, behavioral capability (knowing how), reinforcement, self-regulation, and self-efficacy. Self-efficacy grows from four sources, strongest first: mastery experiences (doing it successfully), vicarious experience (seeing a similar person succeed), verbal persuasion, and physiological and emotional states.

Theory of Planned Behavior — intention is the direct predictor of behavior. Intention depends on attitude toward the behavior, subjective norms (what important others expect), and perceived behavioral control.

Pender's Health Promotion Model — explains health-promoting (not disease-avoiding) behavior. Three groups of variables:

• Individual characteristics and experiences: prior related behavior; personal biological, psychological, and sociocultural factors
• Behavior-specific cognitions and affect (the main targets of nursing intervention): perceived benefits, perceived barriers, perceived self-efficacy, activity-related affect, interpersonal influences (family, peers, providers), and situational influences
• Behavioral outcome: commitment to a plan of action, immediate competing demands and preferences, and the health-promoting behavior itself

Social Ecological Model — behavior is shaped at several levels, and lasting change needs action at more than one.

PRECEDE-PROCEED Model (Green and Kreuter) — a planning and evaluation model that works backward from the desired outcome.

Choose the theory that fits the question.

• Will people get screened or vaccinated? → HBM (susceptibility, barriers, cues)
• Where is this person in readiness to change? → Transtheoretical Model
• How do we build confidence and skills? → Social Cognitive Theory (modeling, practice, self-efficacy)
• Why does the problem persist despite education? → Social Ecological Model
• How do we plan and evaluate a whole community program? → PRECEDE-PROCEED

Stage-matched counseling (tobacco example). A precontemplator gets personalized, nonjudgmental information and an open invitation; a person in preparation gets a quit date, pharmacotherapy referral, and the national quitline (1-800-QUIT-NOW); a person in action gets follow-up calls and trigger planning.

Evidence-based sources. The Community Preventive Services Task Force ("The Community Guide") reviews population interventions; the US Preventive Services Task Force (USPSTF) rates clinical preventive services. Under the Affordable Care Act, most private plans cover USPSTF A and B services without cost sharing, which lowers a common barrier.

Using Healthy People 2030. Programs align their measurable objectives with national targets and Leading Health Indicators, so local results can be compared and reported.

• Assess beliefs, readiness, self-efficacy, barriers, culture, and health literacy before teaching
• Educator and counselor — use motivational interviewing (open questions, affirmations, reflections, summaries) rather than lecturing or confronting
• Advocate — address barriers the person cannot fix alone (cost, transportation, unsafe environment)
• Collaborator and coalition builder — work with schools, employers, faith groups, and local government on multi-level change
• Policy participant — support evidence-based policy (smoke-free laws, healthy school food)
• Evaluator — measure process, impact, and outcome and share results
• Role model — nurses' own health behaviors influence credibility

• Autonomy vs. paternalism: adults may decline health advice; the nurse informs, supports, and respects choices without coercion or shaming
• Avoid victim-blaming: behavior is shaped by environment and resources; programs must not treat poor health as purely personal failure
• Justice and equity: prioritize groups with the greatest burden and least access (a Healthy People 2030 goal)
• Confidentiality: screening and program data are protected health information when collected by covered health care entities (HIPAA); report only de-identified data publicly
• Informed consent and honesty: do not exaggerate risk to create fear; accurate risk messages keep trust
• Law as a health tool: the federal minimum age for buying tobacco products is 21 (Tobacco 21, enacted December 2019); many health promotion gains come from such policies rather than education alone
• Documentation: record counseling given, stage of change, the plan, and referrals

Case 1 — Mammography outreach. Screening rates are low in a rural county. Focus groups show many women believe "no family history means no risk," and the nearest imaging center is 60 miles away.

Action: correct the susceptibility belief with local data and peer stories, and reduce barriers with a mobile mammography day and reminder calls (cues to action).

Why: the HBM identifies both the belief problem (susceptibility) and the practical barrier; education alone would not fix transport.

Case 2 — Relapse after quitting. A client quit smoking for 3 weeks, then resumed during a family crisis and now says, "I'm a failure."

Action: normalize relapse as part of change, review what worked, identify the trigger (stress), and set a new quit date with coping and medication plans.

Why: in the Transtheoretical Model, relapse means recycling to an earlier stage; building self-efficacy prevents giving up.

Case 3 — Childhood obesity program. A school district wants to lower obesity rates. A nurse proposes classroom nutrition lessons only.

Better action: add interpersonal (family cooking nights), organizational (healthier cafeteria choices, daily activity), community (safe routes to school), and policy (limits on sugary drinks) components.

Why: the Social Ecological Model shows single-level programs rarely sustain change.

• Confusing susceptibility (chance of getting it) with severity (how serious it is)
• Calling perceived barriers a Social Cognitive Theory construct — it belongs to the HBM (and Pender); SCT's hallmark is reciprocal determinism, modeling, and self-efficacy
• Giving an action plan to a precontemplator — first raise awareness
• Mixing up stage time frames: contemplation = within 6 months; preparation = within the next month; maintenance = 6 months or more
• Mislabeling PRECEDE factors: knowledge and beliefs = predisposing; access, cost, skills = enabling; family praise or peer approval = reinforcing
• Confusing evaluation phases: delivered as planned = process; behavior or knowledge change = impact; morbidity, mortality, quality of life = outcome
• Assuming knowledge equals behavior change
• Treating Pender's model as disease-avoidance; it explains health-promoting behavior

• Primary = prevent onset; secondary = early detection (screening); tertiary = limit disability
• HBM: susceptibility, severity, benefits, barriers, cues to action, self-efficacy — best for screening and vaccination decisions
• Transtheoretical stages: precontemplation → contemplation (6 months) → preparation (1 month) → action (< 6 months) → maintenance (≥ 6 months); relapse = recycling
• Social Cognitive Theory: reciprocal determinism, observational learning, self-efficacy (mastery experience is the strongest source)
• Theory of Planned Behavior: attitude + subjective norms + perceived control → intention → behavior
• Pender: behavior-specific cognitions and affect are the modifiable targets
• Social Ecological Model: individual, interpersonal, organizational, community, policy — community-level change means environments such as parks and sidewalks
• PRECEDE: social → epidemiological/behavioral/environmental → educational/ecological (predisposing, enabling, reinforcing) → administrative/policy; PROCEED: implementation → process → impact → outcome evaluation
• Healthy People 2030: national objectives, social determinants in five domains, focus on equity and health literacy
• Ottawa Charter: healthy public policy, supportive environments, community action, personal skills, reoriented health services
