This study evaluated the efficacy of a theory of planned behaviour (TPB) based intervention to increase fruit and vegetable consumption. The extent to which fruit and vegetable consumption and change in intake could be explained by the TPB was also examined. Participants were randomly assigned to two levels of intervention frequency matched for intervention content (low frequency n=92, high fre...

The Theory of Planned Behaviour (TPB) has been widely applied to the explanation of health and social behaviours. However, despite its potential to inform behaviour change efforts, there have been surprisingly few attempts to use the TPB to design actual interventions. In 1998, the Scottish Road Safety Campaign implemented a 3-year mass media campaign to reduce speeding on Scotland's roads whic...

METHOD Participants completed items assessing theory of planned behaviour (TPB; attitude, subjective norm...

The Theory of Planned Behaviour (TPB) has received considerable attention in the literature. The present study is a quantitative integration and review of that research. From a database of 185 independent studies published up to the end of 1997, the TPB accounted for 27% and 39% of the variance in behaviour and intention, respectively. The perceived behavioural control (PBC) construct accounted...

We examined goal importance, focusing on high, but not exclusive priority goals, in the theory of planned behaviour (TPB) to predict students’ academic performance. At the beginning of semester, students in a psychology subject (N = 197) completed TPB and goal importance items for achieving a high grade. Regression analyses revealed partial support for the TPB. Perceived behavioural control, bu...
