Theories of behaviour change Flashcards
What are the theories of behaviour change applied to addiction
- Theory of planned behaviour
- Prochaska’s 6 stage model of behaviour change
Outline the premise of theory of planned behaviour
- We change out behaviour deliberately through rational desicions.
- The TPB asserts that our behaviour can then be predicted from our intentions.
- The TPB suggests our intention to use (or give up) drugs arises from 3 key influences: our personal attitudes, subjective norms and percieved behavioural control.
How many components are there for the theory of planned behaviour (TPB)

What are the components of the theory of planned behaviour
- Personal attitudes
- subjective norms
- percieved behaviour control
- behavioural intention
What can the theory of planned behaviour (TPB) explain
TPB can explain why someone may be successful in quitting addictive behaviours and why someone else might not.
TPB
Outline 1. personal attitudes
An addicted persons attitudes are a combination of favourable and unfavourable opinions about their addiction.
Favourable attitudes of addiction come about if the person believes the outcome accociated with gambling (/the addiction) is positive. Attitudes may become unfavourable which leads to a reduced interest in addiction-related behaviour.
1. Personal attitudes
Accourding to Theory of planned beahaviour (TPB) what will be the outcome for a gambler who evaluates to find they have a negative attitude towards gambling
they will likely form an intention to gamble less
Outline 2. Subjective norms
- Subjective norms are the addicted persons’ beliefs about whether those who matter to them most approve or disapprove of their addictive behaviour.
- The beliefs are based on what the addicted person belives to be the normal behaviour.
2. Subjective norms
According to the theory of planned behaviour (TPB) what will be the outcome of the addict believing their friends and family would be unhappy with them gambling.
This would likely lead to them forming an intention not to gamble and therefore making them less likely to actually gamble.
Where have 2. subjective norms been used in real life
O’Connell et al 2009:
found that the students often overestimate the amount their peers are drinking so drink more to keep up with the percieved norm
Outline 3. Percieved behavioural control
- percieve behavioural control is about how much control we believe we have over our behaviour (i.e. self-efficacy)
- Their percieved behavioural control depends on their perception of the resources available to them, both external (time, support) and internal (ability and effort).
- It can have 2 effects - direct or indirect
Explain what is mean by directly and indirectly effecting behaviour in 3. Percieved behaviour control
- Indirectly: it can influences through intentions - the more control they believe they have the stronger their ability to do so.
- directly: the greater their percieved control over their gambling the longer and harder they will try to stop.
how do therapist influence percieve behavioural control
By increasing an addicts self-efficacy they can help them quit and/or avoid relapse.
This is done by encouraging an optimistic outlook and confidence in their ability along with the understanding that quitting/ abstaining will require effort.
Outline 4. behavioural intention
- Is the person likely to stop their addictive behaviour? will the treatment plan work?
- This is the last stage and is made up of the 3 other stages:
e.g. if they realise their addiction is dangerous, if their social group supports the change and if the individual believes they can succeed - then the treatment programme is more likely to work
