Chapter 14, Week 4 Flashcards
Health psychology
is devoted to under- standing psychological influences on how people stay healthy, why they become ill and how they respond when they do get ill
i.e. they study why people fail to exercise even tho they know the health benefits of doing so
trephination
practice of drilling holes in the skull to allow the evil spirits to escape
–> derived from early theorists believing that illness is caused by evil spirits
Hans Selye’s general adaptation syndrome
GAS
alarm, resistance and exhaustion.
Psychoneuroimmunology
examines the influence of psychosocial factors on the functioning of the immune system.
i.e. Stress can affect physical health in two ways: directly, by weakening the immune system, and indi- rectly, by leading to behaviours that weaken the body’s defences or lead to exposure to pathogens.
Cartesian dualism,
Descartes
which contends that the mind and the body are completely separate entitie
biomedical model
reductionistic view of illness, reducing disease to biological causes at the level of individual cells
–> ignores the psychological and social factors that affect illness
leading cause of death - modifiable behaviour
smoking
cellular theory
increased focus on the body as the source of illness
Psychosomatic medicine
the idea that changes in physiology mediate the relationship between unconscious conflicts and illness
- -> from freud
- ->
Wellbeing
is defined as the state of being comfortable, healthy or happy
An individual’s health and well- being is multidimensional, with environmental, social, biological, lifestyle, spiritual, vocational, societal and socioeconomic factors all interacting
Theories of health behaviour
Theories that have been proposed to explain why people engage in health promoting or health compromising behaviours
Health belief model
suggests that health behaviours are predicted by four factors.
- perceived susceptibility tp threat
- perceived seriousness of threat
- benefits and barriers of health behaviours
- cues to action
Perceived susceptibility
refers to a person’s perception that he is likely to contract a particular illness
i.e. family member had disease, so likely to think they will contract it as well
Optimistic bias
Unrealistic optimism
refers to the belief that they are far less likely than other people to contract a particular illness
i.e. “I won’t get Covid-19” I can do what I want, when really you have an equal chance to contract it as everyone else
Perceived seriousness or severity
refers to an individual’s perception of the impact of a particular illness would have in her life
i.e. the more pain and discomfort associated with a health threat, the more severe it is perceived to be
–> cancer, because a lot of people die from it, is considered serious disease
Benefits and barriers to health behaviours
People evaluate the BENEFITS to be gained to stop unhealthy behaviours or adopt a health behaviour as well as outweigh the costs or BARRIERs associated with termination of behaviour
eg. quitting smoking is beneficial to offset diseases like lung cancer, but it is difficult to quit because they might experience withdrawal, weight gain, alienating peers (barriers)
Cues to action
refer to ancillary factors that influence whether or not a person is willing to begin a healthy behaviour or terminate an unhealthy one
i.e. advice from friends and family, age
Self efficacy
A person’s belief in their ability to successfully undertake a particular action or behaviour
Protection motivation theory of health
Health belief model + self-efficacy
Theory of reasoned action
refers to a social cognitive view of health, postulating that behaviours stem from behavioural intentions
Behavioural intentions
consist of two components: attitudes and subjective norms surrounding the behaviour
