BACKGROUND Rates of non-communicable diseases continue to rise worldwide. Many of these diseases are a result of engaging in behavioural risk factors. Without lifestyle and behavioural intervention, non-communicable diseases can worsen and develop into more debilitating diseases. Behavioural interventions are an effective strategy to reduce the bur...
Article
Media campaigns aim to improve safe food handling behaviours; however, their efficacy is still being determined. As safe egg handling behaviours are among the more difficult safe food handling behaviours to change, media campaigns may benefit from the addition of behaviour change techniques to campaigns to improve efficacy. Thus, the aim of this st...
Article
The prevalence of childhood obesity remains high, even among young children under 5 years of age. As parents are usually the key providers of food within the home for young children, it is important to understand influences on parental snack and beverage provision. Previous research in this domain is yet to investigate the role of both rational and...
Article
Purpose The prevalence of foodborne illness remains high in Australia. In response, government initiatives have been implemented to inform consumers of ways to safely handle food. The aim of this study was to examine the accuracy of prompted and unprompted recall of messages from a safe food-handling media campaign in Western Australia, and whether...
Article
Improving dietary reporting among people living with obesity is challenging as many factors influence reporting accuracy. Reactive reporting may occur in response to dietary recording but little is known about how image-based methods influence this process. Using a 4-day image-based mobile food record (mFR TM ), this study aimed to identify demogra...
Article
Purpose Foodborne illness remains high globally, with the majority of cases occurring in the domestic environment. Research in the safe food-handling domain is limited by the absence of an up-to-date and suitable measure of safe food-handling knowledge for use among consumers, with previous measures limited by questionnaire design features that inc...
Article
Full-text available
Behavioural theories, predictions, and interventions should be relevant to complex, real-world health behaviours and conditions. Habit theory and habit formation interventions show promise for predicting and promoting, respectively, longer-term behaviour change and maintenance than has been attained with theories and interventions focused only on d...

Article
Objective Rigid plastics are accepted by Australian recycling facilities but soft forms are not. Further, single-use soft plastic may only be used once but can take 400 years to break down. As only 12% of plastic is recycled, increasing recycling of soft plastic will decrease negative environmental impacts. This study aims to assess the applicabili...
Article
Full-text available
Objective Habitual behaviours are triggered automatically, with little conscious forethought. Theory suggests that making healthy behaviours habitual, and breaking the habits that underpin many ingrained unhealthy behaviours, promotes long-term behaviour change. This has prompted interest in incorporating habit formation and disruption strategies i...

Article
Objectives: Consumption of excess sugar, a common energy-dense nutrient-poor food, is a risk factor for obesity in school-aged children. Food-specific inhibition training, where responses to palatable food stimuli, such as sweet foods, are consistently and repeatedly inhibited, reduces sweet food intake in adults. However, no studies have yet exam...
Article
Objective Adherence to proper hand hygiene practice is relatively low and is particularly salient in light of the current COVID-19 pandemic. Having a greater understanding of the psychosocial predictors of engaging in proper hand hygiene is warranted. One way to do this is through the application of a combined theory of planned behaviour and tempor...

Full-text available
Structural models of psychopathology have emerged as an alternative to traditional categorical approaches. The bifactor model, which incorporates a general p-factor, has become the preferred structure. The p-factor is claimed to represent a substantive construct or property of the system; however, recent evidence suggests that it may be without sub...
Article
Full-text available
Neurocognitive abilities have frequently been claimed to be involved in the aetiology of psychopathology. Neurocognitive deficits have been reported across many disorders, and theoretical perspectives associate these deficits to the onset and maintenance of the symptomology. Recently, the heterogeneity of symptoms, and comorbidity of disorders, hav...
Article
Worldwide, approximately one in ten people acquire a foodborne disease due to eating contaminated food. This often occurs at home and young adults in particular often lack knowledge of and adherence to safe food-handling recommendations.
