Theory Of Planned Behaviour

Question 1

What does the Theory of Planned Behaviour propose in the context of addiction?

Answer 1

TPB suggests behavioural change results from intention, which is influenced by subjective norms, behavioural attitudes, and perceived behavioural control.

Question 2

What are subjective norms in TPB?

Answer 2

The addict’s beliefs about how others view their behaviour; social pressure can either support or discourage quitting.

Example: friends all drink.

Question 3

What role do behavioural beliefs and attitudes play in TPB?

Answer 3

They reflect the addict’s evaluation of their behaviour as positive or negative, shaping motivation to change.

Example: fun vs. damaging.

Question 4

What is perceived behavioural control in TPB?

Answer 4

The addict’s belief about their ability to quit; this directly influences effort and intention.

Example: confidence in willpower.

Question 5

According to TPB, how does change occur?

Answer 5

Intention leads to behaviour change, though not always. Intention is necessary but not always sufficient for action.

Question 6

What did Armitage & Conner (2001) find in their meta-analysis?

Answer 6

TPB predicts intention well, but intention is not always translated into action. Subjective norms were the weakest predictor.

Question 7

What is a major theoretical weakness of TPB?

Answer 7

It overlooks emotional factors, focusing only on rational, cognitive processes.

Question 8

Why is TPB limited in practical addiction treatment?

Answer 8

TPB predicts intention better than actual behaviour. But in addiction, behaviour change (not just intention) is crucial.
