“…Fresh Facts intervention materials designed to use this technique provided a number of suggestions for preparatory behaviour, such as carrying fruit and vegetables. These techniques may have led to increases in habitual performance of behaviour, a factor which would not be captured by measures designed to assess change in TPB variables, but which would be expected to lead to increased fruit and vegetable consumption (Guillaumie, et al, 2010;Shaikh, Yaroch, Nebeling, Yeh, & Resnicow, 2008).…”

Promoting fruit and vegetable consumption. Testing an intervention based on the theory of planned behaviour

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 frequency n = 102). Participants received TPB-based email messages designed to increase fruit and vegetable consumption, messages targeted attitude, subjective norm and perceived behavioural control (PBC). Baseline and post-intervention measures of TPB variables and behaviour were collected. Across the entire study cohort, fruit and vegetable consumption increased by 0.83 servings/day between baseline and follow-up. Intention, attitude, subjective norm and PBC also increased (p<.05).The TPB successfully modelled fruit and vegetable consumption at both time points but not behaviour change. The increase of fruit and vegetable consumption is a promising preliminary finding for those primarily interested in increasing fruit and vegetable consumption. However, those interested in theory development may have concerns about the use of this model to explain behaviour change in this context. More high quality experimental tests of the theory are needed to confirm this result.Keywords: theory of planned behaviour; fruit and vegetable consumption; behaviour change Like attitude and subjective norm, PBC is thought to influence behaviour through its influence on intention. It is also thought to have a direct influence on behaviour over and above its influence on intention. The extent to which PBC has a direct influence on behaviour is often thought to reflect an individual's actual behavioural control over the target behaviour (Fishbein & Ajzen, 2010). Given the difficulty in directly assessing actual behaviour control for most health related behaviours, PBC is used as a proxy for actual behaviour control the majority of TPB based studies (Armitage & Conner, 2001;Fishbein & Ajzen, 2010;Godin & Kok, 1996).A large number of studies provide support for the utility of the model in the prediction of behaviour (Armitage & Conner, 2001;Godin & Kok, 1996). In the context of fruit and vegetable intake, the model has been reported to account for an average of 41% of the variance in intention and 45% of the variance in behaviour (Guillaumie, Godin, & Vézina-Im, 2010). In their meta-analytic review of psychosocial predictors of fruit and vegetable intake, Guillaumie, Godin, and Vézina-Im argued that the TPB is the most strongly supported model of intention and behaviour (Guillaumie, et al., 2010), and therefore there is sound justification for the use of the model in interventions designed to increase intake of fruit and vegetables (Guillaumie, et al., 2010). TPB and behaviour changeAlthough the predictive utility of the TPB model has been well established, there are relatively few studies which manipulate the cognitions specified in the mod...

“…Essa tendência manteve-se independente da inclusão de outros fatores de confusão. Um dos possíveis mecanismos de ação seria a atuação do apoio social na saúde dos indivíduos por meio da promoção de hábitos saudáveis e redução de comportamentos de risco, ocasionando alterações nos sistemas imunoló-gico, nervoso e cardiovascular 26 recursos materiais, a disseminação de informações preventivas e as respostas diretas ao estresse fisiológico influenciariam estados psicológicos como autoestima, autoeficácia e segurança, interferindo, consequentemente, em comportamentos relacionados à saúde, tais como hábito de fumar, consumo de álcool, alimentação, utilização de serviços de saúde, aderência ao tratamento e prática de exercícios físicos 6,27 . Embora as análises tenham sido conduzidas apenas com o escore global da escala de apoio social, procurou-se entender melhor os resultados, investigando-se a relação de cada uma das dimensões com o desfecho.…”

Estudo transversal de base populacional, com 1.100 adultos de São Leopoldo, Rio Grande do Sul, Brasil, investigou a associação entre aspectos psicossociais e excesso de peso. Entrevistas estruturadas foram realizadas utilizando-se questionário padronizado e pré-testado. Dados antropométricos foram referidos pelos participantes, e excesso de peso foi definido pelo índice de massa corporal (IMC) > 25kg/m². Aspectos psicossociais incluíram qualidade de vida (WHO-8:EUROHIS) e apoio social (Medical Outcomes Study). A análise dos dados foi realizada com regressão de Poisson modificada. Após ajuste para variáveis sociodemográficas e comportamentais, as prevalências de excesso de peso foram 19% (RP = 1,19; IC95%: 1,03-1,38) e 12% (RP = 1,12; IC95% 0,96-1,31) mais elevadas em pessoas com, respectivamente, baixa qualidade de vida e baixo apoio sócial, quando comparadas àquelas com níveis altos ou moderados nestas características. Os achados sugerem que aspectos psicossociais podem apresentar influência no excesso de peso, indicando, assim, a necessidade da atuação interdisciplinar em programas e ações para o controle de peso.

“…Knowledge as a predictor of behaviour has found support in other studies as well (Food Standards Australia New Zealand, 2008). In an comparable field, a meta-analysis of 35 studies by Shaikh et al (2008) recognized knowledge as being one of the strongest predictors of fruit and vegetable consumption.…”

Purpose – The purpose of this paper is to utilise the comprehensive Food Safety Knowledge Instrument to compare food hygiene knowledge across a population of high school and university students in Australia and the UK. Design/methodology/approach – In total, 475 students from secondary schools and universities in Australia and the UK took part in a survey, which included a Food Safety Knowledge Instrument and demographic items. Findings – Food safety knowledge was generally very low. High school students had a mean score of only 38 per cent, while university students just reached a “pass” with a mean of 54 per cent. Demographics accounted for 41 per cent of variance in food knowledge scores. Female gender, being at university rather than high school, and living out of home rather than with parents were associated with greater food knowledge. Residing in Australia rather than the UK and being older were also associated with greater knowledge; however, these findings were subsumed by education group. Socio-economic status was not a significant predictor of food knowledge. Practical implications – Identifying demographic and cultural differences in food knowledge can help to identify at-risk populations to better target in theory and knowledge-based interventions. Originality/value – This study is the first to apply the knowledge instrument in an Australian population. Understanding the baseline knowledge in this population is an important first step at developing effective interventions for food safety.
