Hygienic food handling behaviours. An application of the Theory of Planned Behaviour

Predicting food hygiene. An investigation of social factors and past behaviour in an extended model of the Health Action Process Approach

“…The people of importance may include parents and friends, but in the context of health behaviours, medical experts and the media may also be considered. In previous research, subjective norm was a significant predictor of food safety behaviours (Clayton & Griffith, 2008;Mullan & Wong, 2009). …”

“…This percentage is rather low compared with that of other health behaviours (Schwarzer et al, 2007), as well as food safety behaviour predicted by TPB. The TPB predicted 21% of variance in food safety behaviour (Mullan & Wong, 2009), suggesting the TPB as a superior model in predicting food safety behaviour. However, it will be elaborated later how the role of past behaviour explains this situation.…”

“…However when used to investigate food safety behaviour (McArthur, Holbert, & Forsythe III, 2006) , it was then found to be lacking in predictive power. The most commonly used model in psychology is the Theory of Planned Behaviour (TPB) and it has been used to investigate different aspects of food hygiene in a number of studies (Clayton & Griffith, 2008;Mullan & Wong, 2009). Mullan and Wong (2009) found that whilst the TPB successfully predicted 66% of intention, it only predicted 21% of behaviour.…”

This suggests that there may be a missing variable between intention and behaviour.…”

“…In research into food handling behaviour, past behaviour was found to predict 19% of behaviour (Mullan & Wong, 2009). …”
