Illness and treatment beliefs and health outcomes in chronic pain
A qualitative investigation of individuals’ lay representations of habit
Objective: While there have been substantive advances in the conceptualisation, measurement, and effects of habit as a psychological construct, there is limited research on individuals’ beliefs and perspectives on habit. The current investigation reports the findings of two studies purposed to explore individuals’ lay representations of habit which further inform habit theory and measurement, and interventions designed to promote habits. Methods:…
Assessment of a workplace training intervention targeting bullying and mental health for construction industry apprentices
The findings from this study provide encouraging evidence for the effectiveness of the overall bullying intervention program. These findings are important for assessing the effectiveness of specific aspects of the training programs, and also provide a baseline measure against which to compare cohorts of apprentices in the future. The results highlight the importance of the bullying intervention program as a long-term investment in apprentices' fu…
Mapping the risk environment for peers with lived-living experience working in the alcohol and other drugs sector in Queensland
Findings highlight the need for advocacy towards legal reform and the creation of inclusive organisational cultures. Recognising and valuing the LLE of peer workers is essential for enhancing harm reduction initiatives and promoting the wellbeing of PWUDs. Addressing these macro- and micro-risk factors, including the importance of peer supervision, can improve peer workers' efficacy in providing meaningful support within their communities
Relative effects of implicit and explicit attitudes on behavior
The present study investigated the unique effects of implicit and explicit attitude forms on behavior and, critically, effects of salient conditions and contextual moderators expected to determine the relative size of each form on behavior in a meta-analytic synthesis review. Specifically, we tested the effects of salient methodological (e.g., methodology used to infer implicit attitude, measure of behavior characteristics, presentation order), c…
A qualitative analysis of parents' beliefs about portable pool safety behaviours
The aim of this study was to develop an in-depth understanding of the beliefs parents hold regarding portable pool safety behaviours using the theory of planned behaviour (TPB). Semi-structured interviews were conducted with parents ( N = 15) of children aged 5 years and younger who owned a portable pool. Interviews examined three key safety behaviours: supervising within arms' reach, fencing portable pools deeper than 30 cm, and emptying and sto…

Longitudinal tests of the theory of planned behaviour
Social cognition correlates of self-management behaviors in patients with familial hypercholesterolemia (FH)
OBJECTIVE: Familial Hypercholesterolemia (FH) is an inherited disorder leading to increased risk of premature atherosclerotic cardiovascular disease. This risk can be ameliorated through adherence to pharmacological treatment and salient lifestyle behaviors (e.g., physical activity participation, healthy eating). Identifying theory-based, modifiable determinants of these behaviors may inform behavioral interventions promoting participation in FH …
A qualitative investigation exploring neighbourhood environment, risks and fear of falling, and fall prevention strategies among urban-dwelling older adults in a high-density city
Falls in older adulthood can have serious consequences. It is therefore important to identify ways to prevent falls, particularly from the voice of older adults. Bottom-up qualitative exploration of the perspectives of older adults can provide rich insights that can help inform the development of effective fall prevention programmes. However, currently there is a dearth of such empirical data, especially among urban-dwelling older adults in high-…
Social cognition, personality and social-political correlates of health behaviors
Findings contribute to an evidence base for the effects of dispositional and social cognition constructs of health behaviors, point to a possible mechanism by which these generalized constructs relate to health behavior, and outline how the pattern of effects varies across the different behaviors
Using an integrated social cognition model to identify the determinants of QR code check-in compliance behaviors in the Covid-19 pandemic
In Australia, checking in while entering venues was a legal requirement during the COVID-19 pandemic to track potential infection sites. This two-wave correlational study used an integrated theory of planned behavior model including moral norms, anticipated regret, and habit to predict check-in compliance in a sample of 181 Victorians (Mean Age = 41.88, 56.4% female) and 162 Queenslanders (Mean Age = 43.26, 47.5% female). Habit and intention pred…
Health action process approach
Based on the health action process approach (HAPA) this study examined whether changes in social cognition constructs could predict change in physical activity and fruit and vegetable intake for adult participants in My health for life, an Australian health promotion behaviour change program. Variance-based structural equation modelling was used to analyse data obtained from Australian adult program participants (n = 167) at baseline (T1), week 1…
Developing habit-based health behaviour change interventions
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 into behaviour change interventions. Yet, notable research gaps limit understanding of how to harnes…

The mediating role of behavioural automaticity and intention on past to future bootcamp attendance
Objective The aim of the current study was to test whether behavioural automaticity and intention mediated the effects of past behaviour on a particular type of vigorous physical exercise: bootcamp attendance.Methods A community sample (N = 69) who had previously attended a bootcamp class was recruited from Queensland, Australia. Participants were asked to complete measures of their previous bootcamp attendance, behavioural automaticity, and inte…
Reciprocal relations between past behavior, implicit beliefs, and habits
The current study assessed cross-lagged relationships between binge drinking, implicit beliefs, and habit in undergraduate university students ( N = 105). Students completed self-report survey and implicit measures in lab visits 3 months apart. A structural equation model revealed cross-lagged relations between habit and behavior, and some evidence for a reciprocal relationship between implicit beliefs and habit. Implicit beliefs were related to …
Perceived behavioral control moderating effects in the theory of planned behavior
OBJECTIVE: According to the theory of planned behavior, individuals are more likely to act on their behavioral intentions, and report intentions aligned with their attitudes and subjective norm, when their perceived behavioral control (PBC) is high. We tested these predictions meta-analytically by estimating the moderating effect of PBC on the attitude-intention, subjective norm-intention, and the intention-behavior relations in studies applying …
Predicting physical distancing over time during Covid-19
Objective: We applied an integrated social cognition model to predict physical distancing behavior, a key COVID-19 preventive behavior, over a four-month period. Design: A three-wave longitudinal survey design. Methods: Australian and US residents (N = 601) completed self-report measures of social cognition constructs (attitude, subjective norm, moral norm, perceived behavioral control [PBC]), intention, habit, and physical distancing behavior on…
Predicting sugar consumption
Excess consumption of added dietary sugars is related to multiple metabolic problems and adverse health conditions. Identifying the modifiable social cognitive and motivational constructs that predict sugar consumption is important to inform behavioral interventions aimed at reducing sugar intake. We tested the efficacy of an integrated dual-process, dual-phase model derived from multiple theories to predict sugar consumption. Using a prospective…
Predicting what mothers feed their preschoolers
BACKGROUND: Healthy eating behaviours are important for physical and mental well-being and developing healthy eating behaviours early in life is important. As parents are the main providers of preschool children's food the main objective of this study was to use the theory of planned behaviour, expanded to include habit and past behaviour, to predict parents' healthy feeding intention and behaviour. METHODS: Theory of planned behaviour, habit str…
Social Influences and the Physical Activity Intentions of Parents of Young-Children Families
Evidence within Australia and internationally suggests parenthood as a risk factor for inactivity; however, research into understanding parental physical activity is scarce. Given that active parents can create active families and social factors are important for parents' decision making, the authors investigated a range of social influences on parents' intentions to be physically active. Parents ( N = 580; 288 mothers and 292 fathers) of childre…

Effects of anxiety and sleep on academic engagement among university students
Objective Poor sleep quality resulting from experiencing anxiety, and low adherence to sleep hygiene behaviours, may lead to poorer academic engagement. The aim of the current study was to elucidate the associations between anxiety, sleep hygiene, sleep quality, and academic engagement of university students.Methods Participants (N = 614) comprised students attending a major university in Australia (n = 329) and Hong Kong (n = 285). A two-wave co…
Predicting limiting ‘free sugar’ consumption using an integrated model of health behavior
Excess intake of 'free sugars' is a key predictor of chronic disease, obesity, and dental ill health. Given the importance of determining modifiable predictors of free sugar-related dietary behaviors, we applied the integrated behavior change model to predict free sugar limiting behaviors. The model includes constructs representing 'reasoned' or deliberative processes that lead to action (e.g., social cognition constructs, intentions), and constr…
Behaviour change techniques to facilitate physical activity in older adults
Physical inactivity in older adults presents a significant problem within modern societies globally. Using a mixed-method approach, this study explored strategies for the development and delivery of physical activity (PA) interventions by investigating what behaviour change techniques (BCTs) are useful, and how these techniques should be implemented to be feasible for older adults. Sixty-six older adults completed a survey indicating the most use…
