emphasises habitual ways of thinking and interpreting events which may lead to the initiation and maintenance of addiction.
Addictions are based on faulty thinking (of various forms) and are often illogical and irrational.
Before an addiction starts, there are main factors that influence the decision to do so
*personal attitude towards the behaviour - do they think it will benefit in the same way
*perception of how others view the behaviour e.g is it socially acceptable
*their perceived control over the behaviour. This is known as the theory of planned behaviour.
~addicts are making a 'rational choice' when they engage in addictive behaviours - they weigh up the costs and benefits of a particular behaviour and then choose to continue with it. BUT they maximise the benefits and minimise the costs.
~particularly at the initiation stage, addicts intentionally use a particular substance/behaviour as a strategy for coping with the demands of life
~feel in control of this behaviour at this stage and view it positively
~when these coping mechanisms are used excessive they may create more problems than they solve
 become psychologically dependent on the behaviour - begin to place irrational importance on it and view it as essential/necessary (mental crutch)
