Using the Theory of Planned Behaviour to design a food hygiene intervention

Abstract

Twenty percent of food poisoning annually in Australia is believed to result from consumer food handling behaviour. Research advocates the use of social cognition theories in designing food hygiene interventions, however very few studies have actually done so. Thus, this study investigated the efficacy of a food hygiene intervention based on the Theory of Planned Behaviour (TPB). One hundred and eighty-four participants completed a TPB questionnaire, including questions regarding past behaviour and food hygiene knowledge, and then were randomly allocated to a knowledge and implementation intention group, a combined knowledge/implementation intention/PBC group, or a control group. Behaviour was measured four weeks later. The TPB predicted a high proportion of variance in both intentions and behaviour, but neither intervention improved participants' food hygiene behaviours. However, knowledge and PBC were significantly increased in the PBC group. The implications of this for future research are explored.

“…Interestingly, some research tested the effect of past behavior as an additional predictor of the intentions and behavior. For instance, Mullan and Wong (2010) used TPB to predict 33% of intentions and 15% of behavior in a food hygiene intervention; the inclusion of past behavior into the model increased the variance accounted for, respectively of 6% and 4%. Mullan and Wong (2009) also found that TPB explained 66% of variance in intention and 21% in behavior of preparing food hygienically.…”

Over-confident and under-competent: exploring the importance of food safety education specific to high school students

“…Students' sense of invincibility and risky food handling practices may stem from their developmental stage, where asynchronous development of the adolescent brain results in increased risk-taking (Smith et al, 2013) and from psychosocial factors linked to poor food safety behaviours, including low perceived behavioural control (Mullan and Wong, 2010;Mullan et al, 2015), low perceived susceptibility (Haapala and Probart, 2004), and learned habits (i.e., past behaviours; Byrd-Bredbenner et al, 2010;Chow and Mullan, 2010;Haapala and Probart, 2004). Since successfully changing risky food handling behaviours is predicated on feeling susceptible to illness, having incentives to take action, and feeling competent to carry out appropriate actions (Schafer et al, 1993), further research investigating psychological factors and how they can influence students' food safety behaviours is needed.…”

Genişletilmiş Planlanmış Davranış Teorisi Kapsamında Yeşil Yıldızlı Otelleri Tekrar Ziyaret Etme Niyeti

“…Ajzen, Fishbein (1980) tarafından geliştirilen PDT modeline göre, niyet, davranışa yönelik tutum ve sübjektif normun yanı sıra algılanan davranışsal kontrolden de etkilenmektedir (Ajzen, 1991;Ajzen, Fishbein, 2008). Algılanan davranışsal kontrol, bireylerin davranışı gerçekleştirmeyi kolay veya zor olarak algılamaları anlamına gelmektedir (Mullan, Wong, 2010). Algılanan davranışsal kontrol, istenilen davranışı gerçekleştirmek için sahip olunan olanaklara yönelik kişinin inancını belirtmektedir (Martin vd., 2011).…”

“…Bu sonuç Alam ve Sayuti (2011), Malezya'da bulunan tüketicilerin 'helal' yiyecek satın alma niyetini PDT kapsamında ele aldığı çalışma ile benzerlik göstermektedir. Ancak bu durum literatürdeki bazı çalışmalardan farklılık göstermektedir (Han, Kim, 2010;Han vd., 2010;Alam, Sayuti, 2011;Beaulieu, Godin, 2011;Forward, 2009;Huang vd., 2011;Martini vd., 2011;Mullan, Wong, 2010;Rah vd., 2004;Teo, Lee, 2010;Vela vd., 2010;Baker, White, 2010;Moan, Rise, 2011;Quintal vd., 2010;Sparks, 2007;Erten, 2002). Bu çalışmadaki katılımcıların algılanan davranışsal kontrole ilişkin ifadelere olan yaklaşımları olumludur.…”
