Theory Of Planned Behaviour Flashcards
What is bi???
The behavioural belief about the consequence of a behaviour
Expectancy = bi
What does the value ei represent?
An evaluation of this consequence
Value = ei
What does attitude equal?
Essentially
expectancy X value is a determinant of behaviour
What are the sources of beliefs/attitudes?
1) direct experience
2) indirect experience - from either a) general communication during socialization
b) watching other’s perform the behaviour
C) inferential reasoning about the behaviour
What is the theory of reasoned action proposed by Fishbein and Azjen (1985)
Attitude and subjective norm -> intention -> behaviour
What is the theory of planned behaviour?
Where attitude, subjective norm and perceived behavioural control -> intention -> behaviour
Dotted link from PBC to behavior, PBC was added for behaviours over which individual has no control
What are the two parts of attitude?
Affective attitude (how it feels)
Instrumental attitude (what you think about it)
What is intention considered as in respect to the TPB?
It is considered the proximal determinant of behaviour and the effect of other variables are mediated through intention
What are the proximal determinants of intention in the TPB?
Instrumental attitude - delayed outcomes
Affective attitude - immediate consequences
Subjective norm - the perceived pressure from significant others
PBC - feeling of control over participation in the behaviour
What did Mcceachan et al and Hagger say was the best predictor of behaviour?
Attitude found to be the best predictor of behaviour (intention)
Lowes,Eves,Carroll (2003) found affective and intention highest (0.56)
What are some measurement issues with the TPB?
PBC includes external factors as well as internal factors
Subjective norm considered weakest of components
Past behaviour found to be more important predictor of behaviour than intention
Attitude often not separated
Eves et al (2003) said what when talking about intention?
That attenuation of attitude and PBC contribution occur when the addition of past behaviour to intention occurs
What did Webb and Sheeran find?
Looked at the effects of intention on behaviour and found habit to be most important
What’s considered most important for exercise intentions?
Affective attitude and PBC also past behaviour
