Theory of Planned Behaviour
Basic belief of TPB?
Decisions can be directly predicted by intention, which is a function of three factors
What factors is intention made up of?
Behavioural attitude, subjective norms and perceived behavioural control
Behavioural attitude is…
personal belief about the likely outcome and beliefs about its value
Subjective norms are…
a product of social influence and norms, which are either descriptive (what other people are doing/will think) or injunctive (what significant others are doing/will think)
Perceived behavioural control is…
the extent to which the individual believes the behaviour is attainable due to internal and external factors
Which one can bypass intention?
Perceived behavioural control
Ways in which TPB can be used as a framework for understanding/treating addiction?
Changing behavioural attitude, changing subjective norms, perceived behavioural control, self-efficacy, using the internet
Research on changing behavioural attitude?
Slater et al
Slater et al?
Target on attitudes may have been what made the ONCPs campaign to lower marijuana use successful
Research on changing subjective norms?
Wilson and Kolander
Wilson and Kolander?
Generally most adolescents don’t smoke, so should be exposed to accurate statistical information to correct subjective norms
Research on perceived behavioural control?
Godin et al
Godin et al?
Perceived behavioural control is the most important predictor of behaviour so should be focussed on
Research on self-efficacy?
Majer et al
Majer et al?
Encouraging an addicts belief in their ability to abstain related to optimism and ultimately a positive outcome
Using the internet with TPB?
Webb et al
Webb et al?
Internet interventions based on theoretical models, especially the TPB, had greater success (85 studies)
Weaknesses of the TPB?
Ignores influence of drugs/alcohol Methodological problems Too rational Difference between intention and expectation Individual differences
Ignoring influence of drugs/alcohol in the TPB?
Steele and Josephs
Steele and Josephs?
Alcohol myopia: decrease in cognitive capacity -> discrepancy between intention and behaviour -> risky behaviours
Methodological problems of the TPB?
Albarracin et al
Albarracin et al?
Attitudes and intentions are usually measured by questionnaire, which are poor representations and predictors
Rationality in the TPB?
Armitage
Armitage?
The TPB fails to include emotions, compulsions and irrational thoughts
Research on difference between intention and expectation in the TPB?
Armitage and Connor
Armitage and Connor?
Intention has a causal effect on behaviour, but expectation is less likely to as there is no actual plan to do so
Individual differences in TPB?
Klag
Klag?
Self-determination theory - recovery consistently more successful in those who’d decided to give up rather than been coerced
Strengths of the TPB?

Effective applications of the TPB?
