THEORY OF PLANNED BEHAVIOUR - Coggle Diagram
THEORY OF PLANNED BEHAVIOUR
overview
proposes that an individuals decision to engage in a behaviour is directly predicted by their intention to engage in that behaviour
model assumes that behaviour is under conscious control
this is a cognitive theory
if an individual intends to abstain from an addictive behaviour, then it should have a direct effect on their future behaviour
intention is affected by three key factors
subjective norms
: their perception of how others view the behaviour, awareness of social norms
'are others engaging in the behaviour'
perceived behavioural control
: their level of self efficacy, the level of confidence they have in their ability to control their behaviour and carry it out successfully. those with higher perceived behavioural control will try harder to control their behaviour and for longer
behavioural beliefs
: the persons own attitudes towards the behaviour, including expectations about outcomes of the behaviour -
'smoking is bad for me'
Godin et al 2002
procedure - data was collected using questionnaires and also at home using trained interviews
ppts were surveyed at the start of the study and again six months later
examined the extent to which the theory of planned behaviour could explain smoking intentions and behaviours in adults intending to give up smoking
findings - found the three elements of TBP helped to explain intentions, perceived behavioural control was the most important predictor of ultimate behaviour change
perceived behavioural control is a better predictor of behavioural change
armitage and conner 2001
especially from difficult behavioural change - eg drugs
fails to explain the processes involved in translating intentions into actions
meta analysis of studies into TPB and concluded that the model was successful in predicting intention to change rather than actual behavioural change
weakness
fails to consider the role of environmental issues and takes a linear approach
individuals may change their behaviour first and then their beliefs/attitudes about it afterwards
individualistic approach
weakness
therefore could be considered reductionist
oversimplifies human behaviour
