A3-Theories- theory of planned behaviour

Question 1

What does this theory state=

Answer 1

behaviour can be predicted by intention- intentions to change behaviour are linked with actual changes in behaviour

Question 2

Who created this model=

Answer 2

Ajzen (1991)

Question 3

Personal attitudes=

Answer 3

these refer to an individual’s favourable and unfavourable beliefs about their behaviour.

Your overall attitude is formed by a balance of positive and negative judgements.

Question 4

link to alcoholism=

Answer 4

favourable= I drink because i enjoy being drunk

Unfavourable= binge drinking makes me anxious and alcoholism is expensive

if you start having more unfavourable beliefs about a behaviour your more likely to have the intention to change it and vice versa

Question 5

subjective norms=

Answer 5

an individual’s perception of social pressures and expectations regarding a specific behaviour

Subjective norm is a person’s perception of the social expectations to adopt a particular behavior.

Question 6

link to alcholism=

Answer 6

An alcoholic might conclude “my family and friends are unhappy with me drinking” this might make them less likely to intend to drink (an ultimately less likely to drink)

Question 7

perceived behavioural control=

Answer 7

how much control we believe we have over behavior

PBC indirectly influences our intentions to behave- if they believe they have more control over their drinking behaviour, the stronger their intention to stop drinking

PBC can also directly influence behaviour- the more they believe they can control a change, the more likely they want to change.

Question 8

link to alcoholism=

Answer 8

does an alcoholic believe it is easy to stop drinking heavily.

Question 9

strength=

Answer 9

scientific evidence to support

Hagger et al- found that personal attitudes, subjective norms and PBC all could predict intention to limit drinking- as well as actual units drank (behavioural change)

These outcomes are exactly what the theory predicts.

Question 10

weakness=

Answer 10

a weakness is that the TPB is a poor tool in predicting long-term change

McEachan et al conducted a meta analysis on TPB and health behaviours

It was found that intention was a good predictor in behaviour change, but did not maintain the lifestyle change

Thus, TPB is a poor predictor of long term change.
