(25 cards)
What does TPB stand for in addiction psychology?
Theory of Planned Behaviour
Who formulated the Theory of Planned Behaviour (TPB)?
Ajzen
What does TPB aim to predict in relation to behaviour?
TPB aims to predict behaviour from our intentions.
List the three key influences on intentions in TPB.
~ personal attitudes
~ subjective norms
~ perceived behavioural control
Define ‘personal attitudes’ in the context of TPB.
A combination of favourable and unfavourable opinions about addiction, based on evaluating positive and negative consequences.
Give an example of a positive personal attitude towards gambling.
Believing the outcomes associated with gambling are positive.
Give an example of a negative personal attitude towards gambling.
Associating gambling with outcomes such as losing more money than winning, feeling trapped, or anxiety.
What are ‘subjective norms’ in TPB?
Beliefs about whether those who matter most approve or disapprove of addictive behaviour.
How do subjective norms influence intentions?
They shape intentions by considering the views of friends and family about the addictive behaviour.
How can campaigns alter subjective norms?
By targeting the perceived approval of peers and highlighting social disapproval of substance abuse.
What is ‘perceived behavioural control’ in TPB?
How much control we believe we have over our behaviour, similar to self-efficacy.
How does perceived behavioural control affect intentions?
The more control we believe we have, the stronger our intention to behave in a certain way.
What factors can increase perceived behavioural control?
Support from others, internal ability (willpower), and external resources (time, help).
How can perceived behavioural control help someone quit gambling?
By increasing optimism and confidence in their ability to stop, and providing resources like support.
What is the definition of TPB?
Changes in behaviour can be predicted from our intention to change, which is the outcome of attitudes, beliefs about others, and perceived control.
Who conducted a study supporting TPB with alcohol-related behaviours?
Hagger et al. (2011)
What did Hagger et al. (2011) find about TPB?
Personal attitudes, subjective norms, and perceived behavioural control correlated significantly with intentions to limit drinking.
What is a limitation of the TPB according to research findings?
It sometimes fails to predict actual addiction-related behaviours.
What are short-term effects in TPB research?
Correlation between intentions and behaviour is stronger when the time between them is short (e.g., less than five weeks).
Who conducted a meta-analysis on TPB and what did they find?
Rosie McEachan et al. (2011) found that the intention-behaviour correlation weakens over longer periods.
What is the ‘intention-behaviour gap’?
The phenomenon where intentions do not always translate into actual behaviour.
Why is the intention-behaviour gap a problem for TPB?
Because TPB cannot adequately explain why intentions do not always lead to behaviour change.
Who highlighted the intention-behaviour gap in gambling?
Robin Miller and Gwyneth Howell (2005)
What does the intention-behaviour gap suggest about TPB’s usefulness?
It questions whether TPB can predict behaviour change at all.
