Topic Synopsis
Health psychology explores how psychological, behavioural, and social factors influence physical health, illness, and healthcare delivery. This subtopic introduces the role of psychology in understanding health, contrasting the traditional medical model—which views illness purely as biological dysfunction—with the bio-psychosocial model that integrates biological, psychological, and social determinants. Learners will gain insight into how these models shape patient care and health outcomes.
Key Concepts & Core Principles
- Homeostasis: The maintenance of a stable internal environment in the body, including temperature regulation, blood glucose control, and fluid balance.
- Body systems: Understanding the structure and function of major systems such as the cardiovascular, respiratory, digestive, and nervous systems.
- Health determinants: Factors that influence health, including genetics, lifestyle (diet, exercise, smoking), environment, and access to healthcare.
- Scientific method: The process of hypothesis testing, data collection, analysis, and drawing conclusions, including ethical considerations in health research.
- Study skills: Techniques for effective note-taking, time management, research using credible sources, and presenting findings in written and oral formats.
Exam Tips & Revision Strategies
- Always define key terms (medical model, bio-psychosocial model, health psychology) in your own words before applying them.
- Use case studies or real-life scenarios to demonstrate how each model would approach a health issue.
- When comparing models, structure your answer with clear headings or paragraphs for each model’s assumptions, strengths, and weaknesses.
- Remember that ‘psychology in health’ encompasses both mental processes and observable behaviours—mention both where relevant.
- In coursework, link theory to practice by referencing how health psychology informs interventions like stress management or health promotion campaigns.
- Use real-life health examples (e.g., chronic pain, diabetes) to illustrate how psychological and social factors interact with biology
- When comparing models, structure your answer with clear headings: Medical Model, Biopsychosocial Model, then a comparison paragraph
- Memorise a simple diagram of the biopsychosocial model to quickly recall its three components under exam pressure
Common Misconceptions & Mistakes to Avoid
- Conflating the medical model solely with outdated practice, rather than recognising its continued role in acute care.
- Describing the bio-psychosocial model as simply ‘adding’ social and psychological factors without explaining dynamic interactions.
- Failing to provide concrete examples of psychological factors (e.g., stress, beliefs, coping styles) in health.
- Assuming that the bio-psychosocial model rejects biological explanations, rather than integrating them.
- Treating the medical model as entirely obsolete rather than recognising its continued value in acute and emergency care
- Confusing the biopsychosocial model with simply ‘being nice to patients’ rather than a formal framework integrating three systems
Examiner Marking Points
- Award credit for accurate definition of the medical model, including its focus on biological causes and cure.
- Award credit for clear explanation of the bio-psychosocial model, demonstrating how biological, psychological, and social factors interact.
- Look for evidence of comparing the two models, highlighting strengths and limitations of each.
- Credit should be given for use of relevant examples (e.g., chronic illness, pain management) to illustrate psychological influences.
- Assess critical thinking when learners suggest how a health psychologist might intervene in a given scenario.
- Award credit for accurately defining the medical model as focusing solely on biological pathology
- Look for explicit identification of biological, psychological, and social factors in the biopsychosocial model with relevant examples
- Credit responses that demonstrate understanding of how stress, beliefs, or behaviour can impact physical health outcomes
