Positive
‘Smoking is not good for my health’ is an example of what type of attitude?

Which part of the TPB refers to addicts taking into account what other people think about their addictive behaviour?
Subjective norms
In relation to subjective norms, what do addicts take into account?
Whether those they care about will approve or disapprove of their addictive behaviour

If they think their friends/family will disapprove of their addictive behaviour
Addicts take into account how much control they believe they have over their own behaviour. This is called
self-efficacy

level of control
What is an example of past experience that could affect a person’s level of control?
If they have successfully given up their addictive behaviour
What is the most important part of the TPB model and why?
Control - without the control, a person is still vulnerable to addiction
Why is control the most important part of the TPB model?
Without the control, a person is still vulnerable to addiction
The more control an individual has…
the harder and longer they will spend trying to stop their addiction
How does control affect a person’s intention to change?
The more control they have, the harder and longer they will spend trying to stop their addiction
All 3 interacting components need to be present to influence a person’s intentions to stop their addiction
True or false?
True
If one component of the TPB model is missing, they will not have an intention to stop so therapy will not be offered
True or false?
True
Therapy can be offered to individuals if they are missing one component of the TPB model
True or false?
False - if one is missing, they will not have an intention to stop
Give one strategy that we can use to change an individual’s attitudes towards their addictive behaviour
Adverts / Leaflets / Presenting them with the negative consequences of engaging in their addictive behaviour
Give one way we can prevent addiction
Changing attitudes from positive to negative
Give one strategy that we can use to change an individual’s subjective norms towards their addictive behaviour
Interventions / campaigns / making clear to the individual their behaviour is unacceptable
Give one strategy that we can use to change an individual’s perceived behavioural control
Diary of resilience / support groups
Which study provides support for the TPB?
Haggar et al. (2011)
How does Hagger et al. (2011) support the TPB?
The three components interacted to affect an individual’s intention to stop drinking
What did Hagger et al. (2011) find?
Personal attitudes, subjective norms and perceived control correlated with the intention to limit drinking
What is a problem with much of the research into TPB?
Relies on questionnaires which are prone to social desirability
What might an individual lie about on questionnaires in research into TPB?
Their intentions towards their addiction
How does the TPB have practical applications?
Can be used to predict who therapy is most likely to be successful for
What is the benefit for the NHS of using TPB in real life?
Helps them to prioritise their limited resources on individuals with high intention to change, reducing waiting times for therapy
TPB assumes addiction is the result of what type of decision?
Rational
What type of decision might addictive behaviour be more influenced by?
Irrational
What type of decision does TPB not account for?
Irrational
