Addiction: The application of theories - The theory of planned behaviour Flashcards
What are the 3 different interacting beliefs that influence the intention to change?
Attitudes
Subjective norms
Control
Explain attitudes
If any individual has more negative attitudes towards their addiction than positive, less likely to intend to do addictive behaviour
Less likely to actually gamble
More likely to chnage their addictive behaviour
Explain subjective norms
If addicted person believes the people who matter most to them disapprove of the addictive behaviour, less likely to indend to engage in addictive behaviour
Less likely to actually gamble
More likely to change their addictive behaviour
Explain Controls
How much control (self efficacy) a person feels they have over the own behaviour and ability to change, influences their intention
Most important part of the model, without control, person is vulnerable to addiction
What is control based on?
Internal factors - how determined they are
External factors - support and time
Past experiences - if they have successfully given up before
1 - Who researched TPB?
Haggar et al
1 - What did Haggar et al do?
Asked 486 ppts to complete questionnaire about their alcohol-related behaviours at the start of the research and then one three months later
1 - What did they find?
Personal attitudes and subjective norms correlated significantly with the intention to limit drinking to match guidelines
Perceived control predicted actual unit consumption increasing its validity in explaining behaviour change in addiction
1 - What is the link?
Supports TPB as the three components interact to effect intention to stop, leading to behaviour change
2 - What is a problem?
Relies on questionnaires, prone to social desirability bias
2 - What may ppts do?
Lie about their intention to gambling to present themselves in the best possible light
E.g., Say they intend to drink within guidelines to avoid being judged
2 - What is the link?
Reduces validity
3 - What is a strength?
Practical Applications
3 - What are the principles?
Principles used to predict who therapy is most likely to be successful for
E.g., if person missing one of the components e.g., attitudes won’t have intention to change, won’t be offered therapy
3 - What will it help with?
The NHS, can prioritise limited resources on individuals with high intentions to chnage, reduce waiting times for therapy
