PSYC 211 Introduction to Health Psychology Study Notes for North-West University (NWU)

These study notes provide a comprehensive, exam-focused guide to PSYC 211: Introduction to Health Psychology in the context of North-West University (NWU). The material covers the core theories, models, and applications most commonly assessed in undergraduate health psychology modules, with a clear emphasis on understanding how behaviour, cognition, emotion, and social context shape health outcomes. It is designed for revision, essay preparation, and concept mastery in a South African university setting.

1. Foundations of Health Psychology

Health psychology is the scientific study of how psychological, behavioural, and social factors influence health, illness, and healthcare. It emerged because the traditional biomedical model, while powerful for diagnosing and treating disease, could not fully explain why some people become ill, why some recover faster than others, or why individuals with the same medical condition often have very different outcomes. For PSYC 211, it is essential to understand that health psychology does not replace medicine; rather, it complements medicine by examining the human factors that affect health behaviour and disease progression.

What Health Psychology Is About

At its core, health psychology asks questions such as:

• Why do some people smoke despite knowing the risks?
• Why do stress and loneliness affect physical health?
• Why do patients differ in how well they follow treatment?
• How do beliefs about illness shape recovery?
• What psychological interventions can improve health outcomes?

The field brings together concepts from psychology, public health, sociology, and medicine. It is concerned not only with treating illness but also with preventing disease, promoting healthy behaviour, and improving quality of life. This broad scope makes it especially relevant in South Africa, where both communicable and non-communicable diseases place major burdens on individuals, families, and healthcare systems.

A useful way to think about health psychology is through three broad goals:

1. Health promotion – encouraging behaviour that supports well-being, such as exercise, balanced eating, adequate sleep, and adherence to medication.
2. Prevention of illness – identifying risk factors early and reducing exposure to harmful behaviours or environments.
3. Treatment and recovery support – improving coping, adherence, and adjustment during illness.

These goals are linked. For example, a person who learns stress-management skills may sleep better, regulate blood pressure more effectively, and be more likely to maintain exercise routines.

The Biomedical Model and Its Limits

The biomedical model views disease primarily as the result of biological malfunction. It focuses on pathogens, genetics, organ dysfunction, and biochemical imbalance. This model has led to major medical advances such as vaccines, antibiotics, surgery, and diagnostic imaging. However, it has limitations when applied alone.

Key limitations of the biomedical model

• It often treats the body as separate from the mind.
• It tends to focus on symptoms rather than the person’s lived experience.
• It may overlook behavioural causes of disease, such as smoking, inactivity, or poor diet.
• It may underestimate the role of stress, social support, and culture in recovery.
• It struggles to explain why people with the same diagnosis respond differently to treatment.

For example, two individuals may both be diagnosed with hypertension. One may take medication consistently, reduce salt intake, and exercise regularly, resulting in good control. The other may forget doses, feel anxious about side effects, and avoid follow-up care, leading to worse outcomes. The biomedical model explains the diagnosis, but not the behavioural differences that shape the disease course.

Health psychology developed in part to fill this gap by adopting a biopsychosocial perspective.

The Biopsychosocial Model

The biopsychosocial model, associated with George Engel, argues that health and illness arise from the interaction of biological, psychological, and social factors. This model is central to health psychology and should be understood as a framework rather than a single theory.

Biological factors

These include:

• Genetics
• Immune functioning
• Hormonal regulation
• Disease processes
• Physical injury
• Age and sex-related vulnerability

Psychological factors

These include:

• Beliefs about health and illness
• Coping style
• Personality
• Motivation
• Emotions such as anxiety, anger, and depression
• Health-related habits and self-regulation

Social factors

These include:

• Family support
• Peer influence
• Work conditions
• Poverty
• Education
• Culture
• Access to healthcare

A person living with diabetes, for example, may struggle not only because of insulin resistance, but also because of depression, food insecurity, transport costs, or limited access to health information. The biopsychosocial model reminds students that health is never purely biological or purely psychological; it is embedded in a social world.

Historical Development of Health Psychology

Health psychology became a distinct field in the late twentieth century as chronic illnesses became more prominent and researchers increasingly recognized the importance of behaviour in disease prevention and treatment. Earlier public health efforts had already shown that health outcomes were tied to sanitation, nutrition, and lifestyle, but the field expanded when psychological research began systematically examining how thoughts, emotions, and habits influence health.

Important developments included:

• Growing evidence that smoking, diet, physical inactivity, and alcohol use contribute to major diseases.
• Recognition that chronic stress affects cardiovascular and immune functioning.
• Increased interest in patient adherence and doctor-patient communication.
• Expansion of health promotion campaigns and behavioural interventions.

In modern university teaching, health psychology is often linked to pressing public health challenges such as obesity, HIV, tuberculosis, cardiovascular disease, cancer prevention, stress-related disorders, and mental health comorbidity. In South Africa, these challenges intersect with inequality, violence, unemployment, and uneven access to healthcare, making the field especially relevant.

Why Health Psychology Matters in South Africa

South Africa faces a complex health profile: communicable diseases remain significant, while non-communicable diseases are also rising. This means health psychology has practical importance across many contexts. A student should be able to connect theory to issues such as:

• Medication adherence in HIV treatment
• Stress and coping in chronic illness
• Substance use and risky health behaviour
• Maternal and child health
• Health beliefs in diverse cultural communities
• The psychological burden of living with poverty or chronic disease

A strong answer in an exam often moves beyond definitions and shows how a model applies to real health concerns. For example, a health psychologist may design an intervention to improve tuberculosis treatment adherence by addressing stigma, transport barriers, side effects, and patient beliefs about medicine. That intervention reflects the biopsychosocial model in action.

Core Assumptions to Remember

A concise way to revise the foundations is to remember these assumptions:

• Health is shaped by more than biology.
• Behaviour affects both physical and mental health.
• Psychological states can influence bodily processes.
• Social context strongly shapes health behaviour.
• Prevention is as important as treatment.
• Patients are active participants in their health, not passive recipients of care.

These assumptions are often woven into exam questions, especially essay prompts asking students to compare models or explain the relevance of health psychology in real-world settings. Mastery of this section provides the conceptual base for everything else in PSYC 211.

2. Major Theories and Models of Health Behaviour

One of the most tested areas in health psychology is the question of why people behave the way they do in relation to health. Knowledge alone is usually not enough to produce healthy action. Many people know that smoking is dangerous, that exercise is beneficial, or that medication should be taken consistently, yet behaviour does not always match knowledge. Health psychology uses models to explain this gap and to predict when people are likely to adopt or maintain health behaviours.

The Health Belief Model

The Health Belief Model (HBM) is one of the oldest and most influential models of health behaviour. It proposes that people are more likely to take action if they believe:

• They are personally susceptible to a health problem
• The problem is serious
• Taking action will reduce the threat
• The benefits outweigh the costs or barriers
• They are exposed to cues that trigger action
• They feel capable of performing the behaviour

Core constructs

1. Perceived susceptibility
   Belief about the likelihood of getting a disease.

2. Perceived severity
   Belief about how serious the disease and its consequences are.

3. Perceived benefits
   Belief that a behaviour will reduce risk or improve health.

4. Perceived barriers
   Belief about the obstacles or costs of the behaviour.

5. Cues to action
   Events or reminders that prompt action, such as symptoms, campaigns, or advice from a clinician.

6. Self-efficacy
   Confidence in one’s ability to perform the behaviour.

Example

A student who avoids vaccination may not think they are at risk of illness, may believe side effects are worse than the disease, and may not trust the healthcare system. An intervention using the HBM would not simply provide facts; it would address perceived risk, explain benefits, reduce barriers, and increase confidence.

Strengths and limitations

The HBM is useful because it helps explain individual decision-making, but it is limited because it often assumes people are rational and overlooks habits, emotion, social pressure, and environmental constraints. In real life, a person may intend to exercise but lack safe spaces, time, or money. Thus, behaviour cannot always be understood through beliefs alone.

The Theory of Planned Behaviour

The Theory of Planned Behaviour (TPB) explains health action through intention. According to this model, the strongest predictor of behaviour is a person’s intention to act, and intention is influenced by:

• Attitude toward the behaviour
• Subjective norm or perceived social pressure
• Perceived behavioural control or belief in one’s ability to perform the behaviour

Example

A person may intend to reduce alcohol use if they believe it is beneficial, if their friends support the change, and if they feel capable of resisting peer pressure. If any of these are weak, the intention may be weaker and behaviour less likely to change.

Why it matters

The TPB is especially helpful for understanding behaviours such as condom use, exercise, dietary change, and screening attendance. It also highlights the social dimension of health behaviour: people do not make decisions in isolation. Family expectations, cultural norms, and peer influence can strongly shape actions.

Limitation

The model assumes that people are mainly rational planners. Yet some health behaviours are habitual, impulsive, or emotionally driven. For example, stress-eating may continue even when a person has a positive attitude toward healthier food choices.

The Transtheoretical Model and Stages of Change

The Transtheoretical Model (TTM), or Stages of Change Model, proposes that behaviour change occurs in stages rather than all at once. The classic stages are:

1. Precontemplation – not considering change
2. Contemplation – thinking about change
3. Preparation – intending to change soon
4. Action – actively changing behaviour
5. Maintenance – sustaining the change over time

Some versions also include relapse, emphasizing that setbacks are common and do not mean failure.

Example

A smoker in precontemplation may deny the risks. In contemplation, they may recognize the harm but feel ambivalent. In preparation, they may buy nicotine replacement therapy or set a quit date. In action, they stop smoking. In maintenance, they work to avoid relapse by managing triggers and stress.

Usefulness

The model is useful because it reminds practitioners that interventions should match readiness to change. A person in precontemplation may need awareness-raising, while someone in preparation may need practical planning.

Critique

The stage boundaries are sometimes too neat. People do not always move in a linear sequence, and change can be more dynamic than the model suggests. Still, it remains a common exam topic because it captures the process of behaviour modification clearly.

Social Cognitive Theory

Social Cognitive Theory, associated with Albert Bandura, emphasizes the interaction between personal factors, behaviour, and environment. The most important concept is self-efficacy, meaning belief in one’s ability to succeed.

Key concepts

• Reciprocal determinism: behaviour, personal factors, and environment influence one another
• Observational learning: people learn by watching others
• Self-efficacy: confidence in one’s ability to perform a behaviour
• Outcome expectancies: beliefs about the consequences of behaviour
• Reinforcement: rewards or punishments that shape future behaviour

Example

A young person may begin jogging after observing a sibling succeed, feeling encouraged by friends, and experiencing improved mood after each run. Their self-efficacy grows as they succeed repeatedly. This theory is especially useful for interventions that use role models, skills training, and gradual goal setting.

Locus of Control

The idea of locus of control, linked to Julian Rotter, concerns whether people believe outcomes are determined mainly by their own actions (internal locus) or by external forces such as fate, luck, or powerful others (external locus). In health psychology, an internal locus of control can support proactive behaviour, but it is not automatically better in every situation. Some health outcomes are influenced by uncontrollable factors, and overly strong internal control beliefs may lead to self-blame when illness occurs.

Comparing the Main Models

Model	Main Focus	Strengths	Limitations
Health Belief Model	Beliefs about threat and action	Good for prevention and screening	Ignores emotion and habit
Theory of Planned Behaviour	Intention as predictor of behaviour	Strong for planned behaviours	Less effective for impulsive or habitual behaviours
Transtheoretical Model	Stages of change	Matches intervention to readiness	Stages are sometimes oversimplified
Social Cognitive Theory	Learning, self-efficacy, environment	Strong for behaviour change programs	Can be broad and complex
Locus of Control	Perceived control over outcomes	Useful for understanding coping	Can oversimplify power and context

Exam Strategy for Behaviour Models

When writing about these models in an exam, avoid listing definitions only. Instead:

1. State the model clearly.
2. Identify its core constructs.
3. Explain how it predicts behaviour.
4. Give a concrete health example.
5. Mention a limitation or critique.
6. Compare it with another model if asked.

A high-quality answer often shows that no single theory explains all health behaviour. The best approach is usually integrative: behaviour is influenced by beliefs, habits, emotions, social norms, and structural conditions at the same time.

3. Stress, Coping, and Psychoneuroimmunology

Stress is one of the most important topics in health psychology because it links psychological experience with physical health outcomes. Students should understand stress not simply as “being busy” or “feeling overwhelmed,” but as a complex process involving perception, appraisal, coping, and physiological activation. Stress becomes relevant to health when it is intense, chronic, uncontrollable, or poorly managed.

Defining Stress

Stress can be understood as a state in which demands exceed a person’s perceived resources. What matters is not only the event itself, but how the person interprets it. One person may experience a job interview as exciting and manageable, while another experiences it as threatening and overwhelming. The difference lies in appraisal.

Primary and Secondary Appraisal

According to cognitive theories of stress, especially the work of Richard Lazarus and Susan Folkman, stress involves two forms of appraisal:

• Primary appraisal: assessing whether an event is irrelevant, positive, or threatening
• Secondary appraisal: assessing whether one has the resources to cope

A person receiving a medical diagnosis may first judge the diagnosis as threatening. They then assess whether they have money, support, knowledge, and treatment options to manage it. If resources appear insufficient, stress increases.

Types of Stressors

Stressors can be classified in several ways:

• Acute stressors: short-term events, such as an exam or an argument
• Chronic stressors: long-lasting difficulties, such as poverty, caregiving, or chronic illness
• Major life events: events requiring adjustment, such as bereavement or divorce
• Daily hassles: smaller but repeated problems, such as transport delays or noisy living conditions
• Traumatic stressors: extreme events involving serious threat, violence, or catastrophe

In South Africa, chronic stressors such as unemployment, financial pressure, community violence, and household instability can have major health consequences over time.

The Stress Response

When the body perceives threat, it activates physiological systems that prepare it for action. The sympathetic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis are central to this response.

Sympathetic nervous system

This system increases heart rate, blood pressure, and alertness. It helps the body respond quickly to danger.

HPA axis

This pathway results in the release of cortisol, a stress hormone involved in energy mobilisation and regulation of many bodily functions.

Short-term activation can be adaptive. It helps a person react quickly during danger or challenge. However, chronic activation can contribute to problems such as:

• Hypertension
• Sleep disturbance
• Digestive problems
• Weakened immune functioning
• Anxiety and depression
• Increased vulnerability to illness

Allostatic Load

The concept of allostatic load refers to the cumulative wear and tear on the body caused by repeated stress activation. This is a powerful idea because it explains how stress can become biologically embedded over time. A person facing ongoing financial strain, caregiving responsibilities, or unsafe living conditions may repeatedly activate stress systems without enough recovery time. Eventually, the body may struggle to maintain balance.

Allostatic load helps connect psychological experience to long-term physical outcomes. It also explains why stress management is not just about feeling calmer; it is about protecting bodily systems from chronic overactivation.

Coping with Stress

Coping refers to the cognitive and behavioural efforts used to manage demands that are appraised as stressful. Coping can be adaptive or maladaptive depending on the situation.

Problem-focused coping

This involves addressing the source of stress directly. Examples include:

• Making a study timetable
• Seeking medical advice
• Budgeting finances
• Creating a transport plan for clinic visits

This style is most useful when the person has some control over the problem.

Emotion-focused coping

This involves regulating emotional distress rather than changing the stressor itself. Examples include:

• Talking to a friend
• Prayer or meditation
• Reframing the situation
• Relaxation exercises

This style is especially useful when the stressor cannot be changed immediately, such as during grief or chronic illness.

Maladaptive coping

Examples include:

• Substance use
• Avoidance
• Denial
• Emotional eating
• Aggression
• Self-harm

These strategies may reduce distress briefly but often create worse long-term outcomes.

Social Support

Social support is one of the strongest protective factors in health psychology. Support can be:

• Emotional support: empathy, care, reassurance
• Instrumental support: practical help, such as transport or money
• Informational support: advice and guidance
• Appraisal support: feedback that helps a person evaluate their situation

For students, it is important to understand that support does not only reduce stress by “making people feel better.” It can also improve coping capacity, encourage adherence to treatment, and reduce the harmful physiological impact of stress. Isolation, by contrast, often worsens health outcomes.

Stress and the Immune System

The field of psychoneuroimmunology studies the interaction between psychological processes, the nervous system, and the immune system. Research in this area shows that stress can influence immune functioning. Chronic stress may reduce the body’s ability to fight infection, slow wound healing, and contribute to inflammatory processes.

This does not mean that stress directly “causes” every illness. Rather, stress can increase vulnerability, especially when combined with other risk factors such as poor sleep, nutrition, smoking, and limited healthcare access. A person under chronic stress may also be more likely to engage in unhealthy coping behaviours, creating a chain of risk.

Stress Management and Intervention

Health psychology uses both individual and community strategies to manage stress. Common techniques include:

• Relaxation training
• Mindfulness-based interventions
• Cognitive restructuring
• Time management
• Problem-solving skills
• Social support enhancement
• Lifestyle improvement such as exercise and sleep hygiene

A good intervention is usually tailored. For example, a student experiencing exam stress may benefit from time management and cognitive reframing, while a caregiver of a chronically ill family member may need practical support, respite, and counselling.

Why Stress Theory Matters for Exams

In exam answers, stress should not be reduced to vague statements like “stress is bad.” Strong answers explain:

• What the stressor is
• How the person appraises it
• Which coping resources are available
• How physiology is affected
• How chronic stress influences illness risk
• Which intervention would be appropriate

This gives a full biopsychosocial explanation. If asked to apply theory, always show the chain from stressor to appraisal to coping to health outcome.

4. Health Behaviours, Lifestyle Risk, and Behaviour Change

A major focus in health psychology is explaining how everyday behaviours contribute to illness or well-being. Many of the leading causes of disease are linked to habits and routines rather than sudden medical events. For that reason, health psychology gives special attention to behaviours such as smoking, alcohol use, diet, exercise, sleep, sexual behaviour, and medication adherence.

Why Behaviour Matters

Behaviour matters because it can either increase risk or protect health. Some behaviours directly affect the body, while others do so indirectly by shaping weight, blood pressure, immune function, injury risk, and mental health. Importantly, behaviour is also influenced by environment. People do not choose in a vacuum; their decisions are shaped by cost, access, education, culture, stress, and social norms.

Smoking and Tobacco Use

Smoking remains one of the clearest examples of a behaviour that damages health over time. It is associated with cancer, cardiovascular disease, respiratory problems, and reduced overall health. Yet many smokers begin in adolescence or early adulthood, when peer influence and risk perception are especially important.

Why people smoke

• Peer pressure and social identity
• Stress relief beliefs
• Habit and nicotine dependence
• Normalisation in the social environment
• Low perceived susceptibility to long-term disease

Behaviour change challenges

Quitting smoking is difficult because dependence is both psychological and physiological. A smoker may want to quit but fear withdrawal, weight gain, stress, or failure. That is why interventions often combine education, self-efficacy support, behavioural planning, and, where appropriate, medical aids.

Alcohol Use and Substance Use

Alcohol and substance use are relevant to both physical and mental health. Health psychology examines patterns of use, motives for use, and contexts that increase risk. Some individuals use alcohol to cope with stress, social anxiety, or trauma. In that sense, the behaviour may serve a short-term emotional function while harming health long-term.

Risk factors for problematic use

• Family history
• Peer group norms
• Stress and coping difficulties
• Trauma exposure
• Limited access to support
• Low self-regulation or impulsivity

Health psychology interventions often focus on reducing risk, increasing awareness, and building alternative coping skills rather than relying only on punishment or fear-based messaging.

Nutrition and Eating Behaviour

Diet is another major determinant of health. Eating behaviour is not just about willpower; it is shaped by hunger, preference, affordability, time, culture, emotional state, and environment.

Psychological influences on eating

• Stress eating
• Emotional eating
• Reward sensitivity
• Food marketing
• Learned preferences from childhood
• Body image and dieting culture

A student living in a residence environment may rely on cheap convenience food because of budget limits, not because of ignorance. A good health psychology perspective recognises structural constraints.

Physical Activity

Exercise contributes to cardiovascular health, metabolic regulation, mood, sleep, and stress reduction. Yet many people struggle to maintain physical activity because of time pressure, lack of safe spaces, fatigue, low motivation, or poor self-efficacy.

Common barriers

• No routine
• Unsafe neighbourhoods
• Cost of gym membership
• Low energy after work or study
• Social embarrassment
• Unclear goals

Behaviour change strategies

• Start with small, realistic targets
• Use social support
• Track progress
• Build cues into daily routine
• Focus on immediate benefits such as mood and energy

Sleep Behaviour

Sleep is often underestimated, but it is essential for cognitive functioning, emotional regulation, and physical recovery. Poor sleep is linked to stress, mood problems, reduced concentration, and poorer health choices. Health psychology views sleep not simply as a biological process but as a behaviour shaped by routines, environment, and stress.

Factors that disrupt sleep

• Irregular schedules
• Screen use before bed
• Worry and rumination
• Caffeine use
• Noise and overcrowding
• Shift work

Good sleep hygiene includes regular bedtime routines, reduced stimulation at night, and managing stress before sleep.

Medication Adherence

Medication adherence refers to how well patients follow prescribed treatment. Poor adherence is a major challenge in chronic illness because medicine only works as intended when used correctly. Reasons for poor adherence include:

• Side effects
• Forgetfulness
• Misunderstanding instructions
• Low trust in healthcare providers
• Depression
• Belief that medication is unnecessary when symptoms improve
• Cost and access barriers

A health psychologist may support adherence through reminders, simplification of routines, education, motivational interviewing, and problem-solving. In South Africa, adherence support is crucial in conditions such as HIV, tuberculosis, hypertension, and diabetes.

Behaviour Change Techniques

Successful behaviour change usually involves more than telling people what to do. Effective techniques may include:

1. Goal setting – specifying a realistic target
2. Self-monitoring – tracking behaviour
3. Feedback – reviewing progress
4. Reinforcement – rewarding success
5. Implementation intentions – planning when, where, and how to act
6. Skills training – practising the behaviour
7. Social support – involving others in change
8. Relapse prevention – preparing for setbacks

For example, a person trying to exercise more may set a goal of walking 20 minutes after class three times a week, record the walks on a phone app, ask a friend to join, and plan an alternative indoor workout for rainy days. This structured approach is far more effective than vague intention alone.

Relapse and Maintenance

Relapse is a normal part of behaviour change, not a moral failure. Many people cycle through change repeatedly before maintaining it. This is why maintenance requires planning for high-risk situations, stress, and boredom. A student who starts eating healthier may revert during exam stress unless they have practical coping strategies and realistic expectations.

The Importance of Structural Factors

A strong PSYC 211 answer should avoid blaming individuals for poor health behaviour. Health choices are shaped by:

• Income
• Food availability
• Transport
• Safety
• Advertising
• Working conditions
• Access to healthcare

This is especially important in South African contexts where inequality can strongly shape health opportunities. The most responsible health psychology position recognises both personal agency and structural constraint.

5. Health, Illness, Healthcare, and Exam Revision Essentials

Health psychology is not only about behaviour change; it also examines how people understand illness, communicate with healthcare providers, and adjust to diagnosis and treatment. This final section brings together the most exam-relevant applied concepts and provides revision guidance for written assessments.

Illness Perceptions and Health Beliefs

People do not respond to illness purely based on medical facts. They develop illness perceptions, or personal beliefs about what the illness is, how serious it is, what caused it, how long it will last, and whether it can be controlled or cured. These beliefs influence coping, treatment adherence, and emotional adjustment.

Common dimensions of illness perception

• Identity: what symptoms are associated with the illness
• Cause: what the person believes caused the illness
• Timeline: whether the illness is acute or chronic
• Consequences: expected impact on life
• Control/cure: belief in manageability
• Emotional representation: feelings linked to the illness

For example, if a person believes diabetes is uncontrollable and will inevitably worsen, they may become hopeless and less likely to manage diet or medication. If they believe it can be controlled with support, they are more likely to engage actively in treatment. These beliefs matter even when the medical diagnosis is identical.

Coping with Chronic Illness

Chronic illness affects identity, relationships, routine, and future planning. Coping includes both practical and emotional adaptation. Patients may need to adjust to pain, fatigue, limitations, side effects, stigma, and uncertainty.

Common coping responses

• Problem-solving and information seeking
• Emotional expression
• Acceptance
• Positive reappraisal
• Avoidance or denial
• Spiritual coping
• Seeking social support

Coping is not automatically good or bad; its effectiveness depends on fit with the situation. Avoidance may be helpful briefly if emotions are overwhelming, but harmful if it prevents treatment. Acceptance may reduce distress when a condition cannot be cured but still needs management.

Patient-Provider Communication

Communication between patients and healthcare professionals is central to outcomes. Good communication improves trust, understanding, and adherence. Poor communication can lead to misunderstanding, fear, and disengagement.

Features of effective communication

• Clear language without unnecessary jargon
• Respectful listening
• Checking understanding
• Shared decision-making where possible
• Sensitivity to culture and language
• Non-judgmental responses to questions or concerns

Patients are more likely to follow treatment when they feel heard and respected. A rushed or dismissive consultation can reduce trust even when the medical advice is correct. This is why health psychology pays close attention to relational aspects of care.

Health Promotion and Prevention

Health promotion refers to efforts that enable people to increase control over their health and improve it. Prevention is usually discussed at three levels:

1. Primary prevention – stopping disease before it starts
   Examples: vaccination, anti-smoking campaigns, safe sex education

2. Secondary prevention – early detection and treatment
   Examples: screening, blood pressure checks, early HIV testing

3. Tertiary prevention – reducing complications after disease has developed
   Examples: rehabilitation, diabetes management, counselling after diagnosis

These levels are important because they show that health psychology is involved before, during, and after illness.

Culture, Diversity, and Health

Culture shapes how people understand symptoms, seek help, and respond to advice. In South Africa, cultural diversity means that health psychology must be sensitive to language, beliefs, family structures, religion, and traditions. Illness may be explained through biomedical terms, spiritual terms, or a mixture of both. Effective intervention does not dismiss these beliefs; it works with them respectfully while still promoting evidence-based care.

Common Exam Themes

Exam questions in PSYC 211 often ask students to:

• Compare the biomedical and biopsychosocial models
• Explain how stress affects health
• Apply the Health Belief Model or Theory of Planned Behaviour to a scenario
• Discuss coping with chronic illness
• Explain why adherence is difficult
• Evaluate a health behaviour change intervention
• Show how social context influences health

A strong answer usually includes:

• A clear definition
• Relevant theory
• Application to an example
• Critical evaluation
• Practical implications

How to Write a High-Scoring Essay Answer

Use the following structure:

1. Introduce the concept
   • Give a concise definition.
2. Explain the theory or model
   • Identify the major components.
3. Apply it to a case or example
   • Show real-world relevance.
4. Critically evaluate
   • Mention strengths and limitations.
5. Conclude with significance
   • Explain why it matters for health outcomes.

Example of application

If asked about stress and illness, do not stop at “stress is bad for health.” Instead, explain how a person appraises a stressor, what coping strategies they use, how chronic activation of the stress response affects bodily systems, and how social support or intervention can reduce risk.

Final Revision Summary

To revise PSYC 211 effectively, focus on these core ideas:

• Health psychology studies the interaction of mind, behaviour, and body.
• The biomedical model is useful but limited.
• The biopsychosocial model is the central framework.
• Behaviour change is explained by several models, not just one.
• Stress affects both psychological and physical health through appraisal and physiology.
• Coping and social support are key protective factors.
• Health behaviours such as smoking, diet, exercise, sleep, and adherence strongly affect outcomes.
• Illness perceptions, communication, and culture shape how people experience care.
• Prevention and health promotion are as important as treatment.

Last-Minute Memorisation Points

• Health psychology = psychological and social factors in health and illness
• Biopsychosocial model = biological + psychological + social interaction
• HBM = threat perception and action
• TPB = intention shaped by attitude, norms, and control
• TTM = stages of change
• Social Cognitive Theory = self-efficacy, learning, environment
• Stress = appraisal of demands exceeding resources
• Coping = efforts to manage stress
• Allostatic load = wear and tear from chronic stress
• Adherence = extent to which treatment is followed

Mastering these concepts gives a strong foundation for success in PSYC 211 Introduction to Health Psychology. The most effective exam answers are not merely descriptive; they are analytical, applied, and balanced. They show that health is shaped by a dynamic interaction of bodies, minds, behaviours, relationships, and social conditions.
