Theories of behaviour change to addictive behaviour Flashcards
what are the two theories of behaviour change
- theory of planned behaviour
- Prochaska’s six-stage model
what is TPB
the theory of planned behaviour
what does TPB say about addiction
the individual’s decision to engage in a specific behaviour can be predicated by their intention to engage in that behaviour
what are the two main parts to TPB
the intention which leads to the behaviour
what are intentions as part of TPB
motivational factors that influence a behaviour
what is the effect of a strong intention
stronger the intention, the more likely it is to be performed
what three variables determine intention
- person’s attitude
- subjective norms
- perceived behavioural control
what is the person’s attitude in TPB
the addicted person’s personal attitudes towards their addiction
what is the person’s overall attitude in TPB formed
by weighing up the balance of the positive and negative evaluations of the addiction
what are the subjective norms in TPB
the individual’s beliefs about whether the people who matter most to them approve or disapprove of their addicted behaviour
what is the key thing to subjective norms in TPB
it is the PERCEPTION of other’s attitudes
what is the key thing to personal attitudes in TPB
it is the OVERALL evaluation of the addiction
what is perceived behavioural control in TPB
the extent to which we believe we can control our behaviour
what two effects of perceived behavioural control
- effects intentions
- affect our behaviour directly
how does percieved behavioural control affect our intentions
the more control we think we have, the stronger our intention to perform the behaviour
how does percieved behavioural control affect our behaviour directly
if we perceive a high level of control we will try harder and longer to suceed
what evidence is there for the importance of perceived behavioural control
a study found the less likely smokers were to believe they would quit, the less likely they were to try
what are the three steps that TPB can be used to reduce addiction
1 - diff personal attitude
2 - change subjective norm
3 - help addict believe in themselves
how can personal attitudes be changed to reduce addiction
see it as a more negative thing
how can subjective norms be changed to reduce addiction
exposure to statistics on the true extent of their addictive behav (how many people smoke)
how can perceived behavioural control be changed to reduce addiction
focus on the willpower and effort required to give up their behaviour
who came up with the six-stage model of behaviour change
prochaska
how did prochaska describe the process of overcoming an addiction
- cyclical process
- doesn’t happen quickly
what did prochaska mean when he described overcoming addiction as a cyclical process
there is some orderly progression through stages but a lot of returning to previous ones - some may even be missed out altogether
