TPB
The theory of planned behaviour is a theoretical model used to make a prediction of the
behaviour in regard to an indivdiual’s intentions (Azjen, 1985). The TPB is the further extension
of the theory of reasoned action (Fishbein and Azjen 1975). This new theory expands on the
previous through taking into account behaviours which require the use of knowledge, skill,
cooperation ands ooportunity (Liska, 1984). There are three separate actions within the TPB;
attitude towards a behaviour, subjective norm, intentions, and perceived behavior control.
Attitude towards behaviour refers to having both positive and negative evaluations about
performing various behaviours and its outcomes and consequences of such (Azjen, 1985). The
outcome of the action is often the factor that decides if an individual will perform the behaviour
or not. Individuals often prefer to take part in behaviours which result in positive conseuqneces,
while avoiding a bheaviour which may result in negartive results (Eagly and Chaiken, 1993).
Subjective norm refers to the social norms and social pressure in regard to a particular
behaviour for example, perceiving others opinions on a certain behaviour before engaging in it.
Asch (1951) asked two groups, one which was a control group, to state whether which line was
longer. The control group which featured no aspects of peer pressure or social conforming,
showed only one incorrect answer out of a group of 35. Although, the other group produced
75% wrong answers at least once in each trial. These findings suggest that behaviour within
social settings can be impacted by the social norm, such as the expectations of beliefs of
others.
Perceived behaviour control refers to the idea of how easy or difficult it is to perform a particular
behaviour in regard to internal skill such as one’s ability and obstacles which could inhibit this
behaviour (Azjen, 1985).
