A3: Theories Of Stress, Behavioural Addiction And Physiological Addiction Flashcards
What is the health belief model (HBM)?
Predicts the likelihood of behaviour change. Key factors are perceived seriousness, perceived susceptibility, cost-benefit analysis, demographic variables, cues to action and self-efficacy.
What are the three steps of the health belief model?
Perceived seriousness
Perceived susceptibility
Cost-benefit analysis
What is perceived seriousness?
How harmful will the consequences be if I do not change my health?
What is perceived susceptibility?
How personally and realistically vulnerable am I to an illness/disease?
What is cost-benefit analysis?
An individual weighs up the balance between the perceived benefits of changing behaviour and the perceived barriers (obstacles to change).
What are the modifying factors of the HBM?
Demographic variables
Cues to action
Self-efficacy
What are demographic variables?
The characteristics of a population and an individual,such as age, sex, education level, income level, marital status, occupation, religion.
What are cues to action?
Internal: e.g. experience of symptoms such as pain
External: e.g. media campaigns, awareness of other people with the disease
What is self-efficacy in relation to the HBM?
Does the individual believe they have the ability to successfully change their health?
HBM: Strength: Williamson and Wardle (2002)
Used the HBM to devise a programme to increase the number of people seeking screening for bowel and colon cancers.
HBM: Strength: Strong Credibility
Developed by heath researchers who worked directly with people who wanted to change their health-related behaviours so they based the model on real life experiences of health problems.
HBM: Weakness: Zimmerman and Vernberg (1994)
Argued that once self-efficacy and demographic factors (and other variables) are added, the HBM becomes a different model altogether.
HBM: Weakness: How rational are we?
Rational decisions on health related behaviours aren’t always made and this model assumes they are but it is unclear whether we make health-related decisions based on logic, emotion, habit or all three.
Locus of control: Rotter (1966)
Proposed that some people believe the things that happen to them are likely under their control.
Internal locus of control
Internals believe they are in control of their own behaviour and attribute their successes/failures to themselves. Positive health related changes are more likely.
External locus of control
Externals do not feel in control and attribute their own successes/failures to luck, circumstance or other people. They feel hopeless to change their health.
LoC: Strength: Avtgis (1998)
Found that high externals were more persuadable and conformist than high internals.
LoC: Strength: Gale et al. (2008)
Measured the LoC of 7551 children aged 10 and found by the time they were 30, internals were less likely than externals to be obese or experience psychological stress.
LoC: Weakness: Rotter (1982)
Later pointed out LoC is only relevant in novel situations as it has little effect on our behaviour in familiar situations where previous experience is always more important.
LoC: Weakness: Krause (1986)
Found that extreme internals respond to unavailable events by becoming stressed, just as externals do (but for different reasons) so bring internal doesn’t automatically protect you from stress.
