What are the supporting studied for the theory of plannned behaviour by azjen
Louis et al 2009
Cooke et al 2016
What was Louis et al 2009 study
Supporting Studies:
Louis et al (2009)
Aim: Looks at the connection the theory of planned behaviour (TPB) as an explanation for decision making and its relationship to stress
Procedure: 154 participants, completed questionnaire re:
•Personal attitude
•Subjective norms
•Perceived behavioural control
•Intentions
Additionally, life stress and body image perception were measured
Findings - Personal attitudes influenced healthy eating, subjective norms did not.
Subjective norms actually predicted unhealthy eating habits (but only at low levels of stress)
Conclusions - Only provides partial support for TBP – impact of all factors is moderated by stress
Strength - Large review of studies which means that researchers could generate credible hypothesis – thus opening doors for future research
Weakness - Correlational studies are common and therefore it cannot be concluded that intentions can cause changes
A better way to measure this would be an experiment which would detect cause-effect relationship
For example, slimming world ‘image therapy’
What is Cooke eat al 2016 study
Cooke et al (2016)
Aim: Research in to the correlation between TPB and intentions/actual alcohol consumption
Procedure: Review of 40 studies measuring intentions to consume alcohol
Personal attitude
Subjective norms
Perceived behavioural control
Intentions
Self-efficacy- belief in your own ability to do something
Findings - Positive correlations between:
Intentions and actual consumption
Intentions and attitudes
Subjective norms and perceived control
Self-efficacy and intention/actual consumption
Conclusions - TPB is useful in understanding intentions to drink alcohol. Interventions should target personal attitudes and intentions
Strength – good at looking at alcohol consumption, covers a large range of studies
Weakness – It is a common study and results were already found. A better way is what can cause the changes and links
