Problem 2 - Planned Behaviour Flashcards
Theory of Planned Behaviour
Extension of TRA (prediction of behaviour)
- theory that links one’s beliefs and behaviour
- suggests that people are much more likely to intend to enact certain behaviours when they feel that they can enact them successfully
- states that attitude, subjective norms, and perceived behavioural control, together shape an individual’s behavioural intentions and behaviours
- developed from Theory of Reasoned action (to improve power of this by adding perceived behavioural control)
- includes perceived behavioural control (TRA does not)
- TPB applied to studies of the relations among beliefs, attitudes & behavioural intentions
- in various fields like advertising, public relations, healthcare, sport management & sustainability
perceived behavioural control PBC
determinant of BI
self-efficacy & controllability
- the individuals perception of the extent of control that he/she has over the performance of the behaviour
self-efficacy
level of difficulty that is required to perform the behaviour
- or one’s belief in their own ability to succeed in performing the behaviour
controllability
the outside factors, and one’s belief that they personally have control over the performance of behaviour or if it is controlled by externally uncontrollable factors
–> high perceived behavioural control increases individual’s confidence in being capable of performing a specific behaviour
Theory of Reasoned Action
includes 2 key Determinants:
- behavioural intentions
- subjective norms
Principles of compatibility - any behaviour consists of
- action
- target
- context
- Time
–> restricted to prediction of volitional behaviour
Application of TPB
- protection behaviours (like sexual behaviours)
- risk behaviours: alcohol, substance use
- detection behaviours: physical activity
Function of TPB
B= w1BI+w2PBC
B: behaviour
BI: Behavioural intention
w1+w2: regression weights
Determinants of Behavioural Intention (BI)
Attitude
Subjective Norms (SN)
Perceived behavioural control PBC
Attitude (determinant of BI)
a learned disposition to respond in a consistently favourable or unfavourable manner with respect to an object
Subjective Norms (SN)
a persons beliefs of whether significant others think he/she should engage in the behaviour
Additional predictors to TPB
- components of intention: how much effort a person exerts
- components of attitudes: affective vs cognitive
- components of norms: injunctive (or prescriptive norm, how one should behave) vs descriptive (how most people usually behave)
- components of PBC: external (e.g. time cooperation with others) and internal (e.g. knowledge, skills, willpower)
4 more predictors:
- anticipated affective reactions (e.g. anticipated regret)
- moral norms
- self-identity
- past behaviour (e.g. experiences)
Belief integrated in TPB
- Behavioural beliefs ((dis)advantages of behaviour)
- normative beliefs (other people/groups to come to mind when thinking about behaviour, what do they think about the behaviour?)
- control beliefs (easy or difficult to perform behaviour)
behavioural beliefs
characteristics, qualities, attributes of object of the specific behaviour
(e.g. what do you see as pros and cons of behaviour x?)
normative beliefs
beliefs of what other people/groups would approve/disapprove when thinking about executing target behaviour
(e.g. are there any groups or people who come to mind when thinking about behaviour X?)
control beliefs
factors and conditions that facilitate or prevent to perform target behaviour
(e.g. what factors might prevent or help you to go jogging regularly?)
