ADDICTION ( the theory of planned behaviour & six stage model ) Flashcards
(5 cards)
Define the theory of planned behaviour
The theory of planned behaviour is a cognitive model that attempts to explain how people make decisions about engaging in addictive behaviours. It proposes that behavioural intentions predict actual behaviour
The theory of planned behaviour predict that behaviour is influenced by three components : attitude towards behaviour , subjective norms and perceived behavioural control outline them
Attitude toward the behaviour - This refers to the individual’s personal evaluation of the behaviour. If a person beliefs the behaviour has positive outcomes they are more likely to form the intention to do it ( stress relief from smoking) however negative beliefs reduce the likelihood of forming the intention
Subjective norms - refers to perceived social pressure from others ( friends , family ) If an individual believes that others approve of the behaviour , they are more likely to intend to do it. However if social norms discourage the behaviour ( anti-smoking culture ) , intentions may be reduced.
Perceived behavioural control - This is the individual’s belief in their ability to carry out the behaviour ( similar to self-efficacy ) If a person believes they can control their addiction ( eg. quit smoking or avoid gambling) , they are more likely to try
Evaluate the theory of planned behaviour
STRENGTHS :
Useful in designing interventions : TPB identifies specific cognitive factors that can be targeted in public health campaigns ( eg. changing attitudes , peer norms ) Has been used to design interventions for smoking cessation , safe drinking , and reducing gambling
Evidence : TPB successful in explaining alcohol and tobacco use among adolescents.
Accounts for individual differences : unlike purely behavioural models , TPB recognises the role of personal beliefs and choices , making it more realistic in modern psychology
LIMITAIONS :
Intention - Behaviour gap : A major criticism is that intentions don’t always lead to behaviour. People may intend to quit an addiction , but still relapse due to emotional states , habitual cues , or lack of willpower.
Overlooks emotional and physical factors : TPB is cognitive and rational , but addiction often involves emotional , impulsive or physiological processes ( eg. cravings, withdrawal ) Doesn’t fully explain why people act against their intentions in the moment
Define prochaska’s six stage model and outline it’s six stages model : precontemplation , contemplation , preparation , action , maintenance , termination
model explains how people intentionally change their addictive behaviours overtime. It recognises that behaviour change is a process not a single event.
Precontemplation : the individual is not considering change and may be unaware that their behaviour is problematic
Contemplation : The person is aware of the problem and begins to think about making a change making pros and cons of quitting.
Preparation : The individual intends to change soon and may start making small adjustments ( eg. cutting down , researching support groups )
Action : The person has actively changed their behaviour , eg. stopped smoking , drinking or gambling. Requires time , energy , and support.
Maintenance : the individual works to sustain the change and avoid relapse. Can last for months or even years.
Termination ( or sometimes relapse ) - The person has no desire to return to the addictive behaviour and fully confident in maintaining change. In some versions , relapse is recognised as a normal part of the process , not a failure
Evaluate Prochaska’s six-stage model of behaviour change
STRENGTHS :
Dynamic and realistic : unlike other models , it recognises that relapse is common and that people can move back and forth between stages. More representative of real-life addiction recovery , which is often non-linear.
Holistic view of change : takes into account cognitive , emotional and behavioural factors at each stage. Recognises that change is a process over time , not a one-time decision.
LIMITATIONS :
Stage boundaries may be arbitrary : Critics argue the divisions between stages are artificial and oversimplified. Behaviour change may not happen in discrete steps , and people may skip or combine stages.
Assumes rational decision - making : Assumes people are able to rationally assess their addiction and act accordingly . May underestimate emotional , social , and environmental influences ( eg. poverty , peer pressure , trauma )
