Major Models in Health Psychology
•biopsychosocial model
•medical model
•motivational model
•health belief model
•theory of reasoned action
•theory of planned behaviour
-the behavioural perspective was one of the first perspectives applied to health psychology
•non-adherance or non-compliance: not sticking to the requirements for the treatment of a
disease
-cognitive factors began to be looked at in addition to behaviour in health psychology
-good health or poor health can be caused by many different causes, therefore we need to
consider a variety of perspectives
•biopsychosocial model: consists of the interaction between biological, social, and
psychological levels
-cancer: biological factors, psych (how people cope with it), social (policies that affect
health regulations)
-preventions: biological (vaccines), psychological, social (policy modifications)
•Medical Model: looks at disease as being entirely physical (completely objective)
-there are differences in the training of medical students and psychologists
-there is a change in the kinds of causes of illness and death, because infectious
diseases are no longer the only illnesses causing death (there are now chronic illnesses)
•Motivational model: we must intend to do something before we do it
•health belief model: analyzes health behaviour in terms of various beliefs
-very influencial model
-readiness to take action in terms of health problems is a function of health beliefs
(something we think to be true concerning health)
-health behaviours are explained by our health beliefs
-Beliefs of the health belief model
-1. A health threat exists (1/3 people will develop cancer, you believe that you could
be the one person who is vulnerable to cancer)
-2. course of action that will help with that threat (knowing that you may get cancer
will influence your behaviour in order to reduce the threat)
-Response ethicacy: how much you believe your response is going to reduce the
threat
-cost-benefit: weighing the cost-benefit of the response in order to decide whether
the response will be a useful way of reducing the threat
-it is also important to consider how much an individual values good health, because
although they can identify the threats, individuals who don’t value health as much as
other values may not act to reduce the threat

Document Summary
Major models in health psychology: biopsychosocial model, medical model, motivational model, health belief model, theory of reasoned action, theory of planned behaviour. The behavioural perspective was one of the rst perspectives applied to health psychology: non-adherance or non-compliance: not sticking to the requirements for the treatment of a disease. Cognitive factors began to be looked at in addition to behaviour in health psychology. Good health or poor health can be caused by many different causes, therefore we need to consider a variety of perspectives: biopsychosocial model: consists of the interaction between biological, social, and psychological levels. Cancer: biological factors, psych (how people cope with it), social (policies that affect health regulations) Preventions: biological (vaccines), psychological, social (policy modi cations: medical model: looks at disease as being entirely physical (completely objective) There are differences in the training of medical students and psychologists.
