Theory of planned behaviour
IT attempts to reduce addictive behaviour and encourages people to change their behaviour
The theory of planned behaviour is an adaptation of the theory of reasoned action. This
explained the idea of dealing with addictive behaviours due to decision making and factors
supporting decision making rather than factors that remained there before then. Explains
how various factors lead towards and intension to do something.
There are three components:
Behavioural beliefs: the extent to which the addictive behaviour is seen as negative
or positive by the person who is attempting to do it. If it is positive then it is more
likely to happen. How the behaviour is expected to turn out like and what the
effects will be.
Normative beliefs: Behaviour expected of a relevant social group. This therefore
measures how much the person wants to stay within this relevant group and how
far they will go to stay part of one. This can either be friends or family. The closer
they are to the person the more important and influential they are.
Control beliefs: Peoples belief to perform a predicted behaviour. Perceived
behavioural control and intension can be used to predict behaviour. Their locus of
control helped identify what processes that need to be carried out in order to make
them take control of their own recovery. If
they have an external locus of control it
must be changed in order to make the
patient take responsibility for their actions.
The theory of planned behaviour allows
assessment of motives for continuing with
addictive behaviour and their personal belief and
ability to give up. These help us quit and resist
withdrawal symptoms. To succeed a person's
behavioural control must be high enough to
convince them that they can conquer all difficulties. For example a smoker must think that
they definitely won't go anywhere to buy cigarettes or smoke them. Thee more that
someone believes that they have behavioural control means they are more likely to quit.

It can also depend on external factors such as if someone who lives with you smokes. If
someone has an external locus of control it is likely that they can't quit if the attitudes of
the people around them are opposing.
We must feel confident in our skills and ability to achieve desired behaviour and therefore
understand motivation. For example if you don't think that you will be able to quit then it is
likely that there won't even be an attempt.…read more

Only considers attitudes and beliefs therefore others need to be considered such as
anticipated regret and the strength of emotional disappointment.
