GPH 47: Sociology and Psychology

In this episode, Medlock Holmes turns his attention from pathogens and probabilities to people and power. Public health is not solely biological - it is deeply social and psychological.We explore how sociology examines the structures that shape health: social class, inequality, institutions, norms, culture, and power dynamics. Holmes investigates how social determinants such as income, education, occupation, gender, and ethnicity influence exposure to risk and access to protection.The episode then shifts to psychology, examining individual-level processes that influence behaviour: perception of risk, motivation, cognition, emotion, habit formation, and decision-making.Holmes guides us through key theoretical frameworks:* Social gradient in health* Social capital and social networks* Health belief model* Theory of planned behaviour* Stages of change* Stress and coping theoryWe examine how structural forces and individual agency interact - how context shapes choice, and how behaviour influences disease patterns.This episode reinforces a crucial truth: effective public health interventions must account not only for pathogens and policies, but for people’s lived realities.Health behaviours do not occur in a vacuum. They are socially patterned and psychologically mediated.Key Takeaways* Social determinants strongly influence health outcomes.* Inequality often translates into health disparities.* Psychological theories help explain health behaviours.* Social context shapes risk exposure and health choices.* Behavioural change requires more than information.* Social networks and norms influence population health trends.* Integrating social science strengthens public health strategy.
