Efficacy of health behaviour interventions using the health action process approach
Demand and experimenter bias and the ego-depletion effect
Illness and treatment beliefs and health outcomes in chronic pain
How do people manage desirable but disruptive competing behaviors to successfully reach their health goals? A dual-phase dual-process (DP2) model
OBJECTIVE: Health behaviour change can be facilitated by the use of self-directed situational strategies that assist with the management of alternative behaviours that potentially compete with, and disrupt, health goal-directed behaviour performance. The strategies are likely especially efficacious for highly-rewarding alternative behaviours instigated by strongly-associated cues. However, theoretical accounts describing the determinants of self-…
How do traits and dispositional constructs relate to intentions and behavior? The trait-informed attitude, cognition, and intention tenet (Tacit)
A mechanistic model outlining a process by which dispositional or trait-like constructs (e.g., personality factors such as conscientiousness and extroversion, trait self-control, health literacy, political beliefs) relate to intentions toward, and performance of, future health promoting or health risk behaviors is proposed. Building on basic assumptions relating to the role of dispositional constructs in the social cognition theories typically ap…
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:…
A healthy lifestyle is a journey’
OBJECTIVE: The aim of this study was to explore health perceptions and self-defined facilitators to health in general population. An additional aim of the study was to assess if these perceptions were connected with the context of the Covid-19 pandemic. DESIGN: = 50) were asked to answer the question: 'What does it mean to be healthy?'. Data were collected online in Poland. We generated and interpreted the main themes associated with common perce…
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…
Theory of planned behavior constructs as mediators of relations between personality traits, trust, and Covid-19 preventive behavior adherence
Psychological and socio-structural determinants of intentions to use drug checking services
This study explored the determinants of intentions to use drug checking services among Australian undergraduate students ( N = 324, M age = 22.32 years, SD = 7.21) using an integrated theoretical model that includes social cognition constructs (risk perception, subjective norms, attitudes), health and drug literacy, and socio-structural factors (education, race, employment). A cross-sectional correlational survey design and path analysis revealed…
Adaptation and validation of the stress control mindset measure in Italian university students
Protecting children from Covid-19
OBJECTIVES: This longitudinal study applied the integrated model of self-determination theory (SDT) and the theory of planned behaviour (TPB) to explain COVID-19 preventive behaviours among parents of young children in the United States. DESIGN: = 681) completed self-report questionnaires related to measures of SDT and the TPB constructs and behavioural adherence at baseline and after one month. We used standardised residual change scores to test…
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
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…
Effectiveness of a theory-driven mHealth intervention in promoting post-surgery rehabilitation adherence in patients who had anterior cruciate ligament reconstruction
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…
Application of the trans-contextual model to predict change in leisure time physical activity
OBJECTIVE: This study tested effects of changes in the psychological constructs of the trans-contextual model (TCM) on changes in adolescents' outside of school moderate-to-vigorous physical activity (PA) measured using self-report and accelerometer-based device. DESIGN: A three-wave longitudinal design was used. High school students (N = 331) completed measures of all the TCM constructs at Time1 and at Time2, five weeks apart. Self-reported PA b…
Loudness Perceptions Influence Feelings of Interpersonal Closeness and Protect Against Detrimental Psychological Effects of Social Exclusion
We propose that perceptions of auditory loudness and interpersonal closeness are bidirectionally related. Across 12 experiments (total N = 2,219; 10 preregistered; with Singaporean, British, U.S. American, and Australian participants), we demonstrated that louder audio made people feel physically (Study 1a) and socially (Study 1b) closer to others, presumably because loudness activates interpersonal closeness-related concepts implicitly (Studies …
Proposing a new approach to funding behavioural interventions using iterative methods
Current research funding models for health psychologists tend to be biased toward support for large-scale 'definitive' behavioural trials. This approach emphasizes rigorous tests of one or more key questions, but, unintentionally, may lead to the funding of interventions that are based on myriad untested assumptions. We propose that future funding models should provide support for 'iterative' research that tests assumptions at each stage of the i…
Effects of socio-structural variables in the theory of planned behavior
Objective: Observed variation in health behavior may be attributable to socio-structural variables that represent inequality. We tested the hypothesis that variability related to socio-structural variables may be linked to variation in social cognition determinants of health behavior. A proposed model in which effects of socio-structural variables (age, education level, gender, income) on health behavior participation was mediated by social cogni…
Ego depletion and the strength model of self-control
According to the strength model, self-control is a finite resource that determines capacity for effortful control over dominant responses and, once expended, leads to impaired self-control task performance, known as ego depletion. A meta-analysis of 83 studies tested the effect of ego depletion on task performance and related outcomes, alternative explanations and moderators of the effect, and additional strength model hypotheses. Results reveale…
The reasoned action approach applied to health behavior
The common sense model of self-regulation
According to the common-sense model of self-regulation, individuals form lay representations of illnesses that guide coping procedures to manage illness threat. We meta-analyzed studies adopting the model to (a) examine the intercorrelations among illness representation dimensions, coping strategies, and illness outcomes; (b) test the sufficiency of a process model in which relations between illness representations and outcomes were mediated by c…
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…
Effects of an autonomy-supportive intervention on tutor behaviors in a higher education context
Causality orientations moderate the undermining effect of rewards on intrinsic motivation
Influences of perceived autonomy support on physical activity within the theory of planned behavior
Three studies tested the contribution of perceived autonomy support to the prediction of health‐related intentions within the theory of planned behavior. Perceived autonomy support refers to the extent to which individuals perceive that significant others encourage choice and participation in decision‐making, provide a meaningful rationale, minimize pressure, and acknowledge the individual's feelings and perspectives. Findings from Studies 1 and …
Vicarious Growth in Wives of Vietnam Veterans
There is a paucity of research understanding the “lived experience” of psychological growth following vicarious trauma. This idiographic study explores the phenomenological experiences of wives of Vietnam veterans exposed to vicarious combat trauma over decades. Using semistructured interviews, data were collected from wives of Australian veterans and analyzed using interpretative phenomenological analysis. Two main themes emerged: (a) “Living wi…
The Cognitive Processes by which Perceived Locus of Causality Predicts Participation in Physical Activity
The present study examined the cognitive processes by which perceived locus of causality influences participation in leisure time physical activity. Based on the theoretical tenets of self-determination theory, it was hypothesized that deliberative modes of information processing and past behaviour will account for the direct effects of perceived locus of causality on effort and physical activity. Data from self-report questionnaires were analyse…

The mediating role of constructs representing reasoned-action and automatic processes on the past behavior-future behavior relationship
Time to Set a New Research Agenda for Ego Depletion and Self-Control
The conceptualization of self-control capacity as a domain-general limited resource, and the accompanying state of low self-control resource, known as the ego depletion effect, has received considerable attention in social psychology literature. The effect has also been widely publicized in popular media largely due to its elegant simplicity and intuitive appeal. Since its inception (Baumeister, Bratslavsky, Muraven, & Tice, 1998; Muraven, Tice, …
Predicting fruit and vegetable consumption in long-haul heavy goods vehicle drivers
Fruit and vegetable intake is insufficient in industrialized nations and long-haul heavy goods vehicle (HGV) drivers are considered a particularly at-risk group. The aim of the current study was to test the effectiveness of a multi-theory, dual-phase model to predict fruit and vegetable consumption in Australian long-haul HGV drivers. A secondary aim was to examine the effect of past fruit and vegetable consumption on model paths. A prospective d…
From perceived autonomy support to intentional behaviour
Predicting intention to participate in self-management behaviors in patients with Familial Hypercholesterolemia
Evaluating the effects of implementation intention and self-concordance on behaviour
The purpose of the present study was to investigate effects of implementation intentions on taking one multivitamin tablet, everyday, for 2 weeks, among individuals who endorsed self-concordant and self-discordant forms of motivation. A 2 (implementation intentions: yes, no)×3(motivation: self-concordance, self-discordance, control) experimental design was adopted with university students being exposed to manipulations of implementation intention…
Extending the trans-contextual model in physical education and leisure-time contexts
Background. The trans-contextual model (TCM) is an integrated model of motivation that aims to explain the processes by which agentic support for autonomous motivation in physical education promotes autonomous motivation and physical activity in a leisure-time context. It is proposed that perceived support for autonomous motivation in physical education is related to autonomous motivation in physical education and leisure-time contexts. Furthermo…
A Pipe Roll for 25 Henry I
This note brings to wider attention a passage from a lost pipe roll of Michaelmas 1124 that was copied into a fourteenth-century register from St Albans abbey. The note considers the subject of the excerpt itself, why it was copied into the manuscript, and why we can be sure that the attribution to ‘the great roll of the year 25 Henry the first’ given by the copyist can be trusted. The entry in the St Albans manuscript proves, as has long been su…
Physical Self-Perceptions in Adolescence
This study examines the generalizability of the form, structural parameters, and latent means of a hierarchical multidimensional model of physical self-perceptions in adolescents from three cultures. A children's version of the physical self-perception profile (PSPP-C) was administered to samples of British, Hong Kong, and Russian high school students. A structural equation model that hypothesized a hierarchical structure with global self-esteem …
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…
The influences of intrinsic motivation on execution of social behaviour within the theory of planned behaviour
The present study examined the utility of two forms of measurement of intrinsic motivation in increasing the predictive validity of the theory of planned behaviour. Self-report questionnaires were administered to school pupils (n = 174), University students (n = 129) and adults (n = 157). The data were analysed using confirmatory factor analysis and regression analysis. Confirmatory analysis supported discriminant validity between Forms A and B m…

Children's Physical Activity Levels and Attitudes Towards Physical Activity
This study investigated the relationship between attitude towards physical activity and physical activity behaviour and the influence of gender and season on physical activity level in 45 primary school children, aged 9 to 11 years. Attitudes towards physical activity were assessed using two different theoretical approaches: the children's attitudes towards physical activity (CATPA) inventory and the theory of reasoned action (TRA) questionnaire.…
A Meta-Analytic Review of the Theories of Reasoned Action and Planned Behavior in Physical Activity
The aim of the present study was to examine relations between behavior, intentions, attitudes, subjective norms, perceived behavioral control, self-efficacy, and past behavior across studies using the Theories of Reasoned Action (TRA) and Planned Behavior (TPB) in a physical activity context. Meta-analytic techniques were used to correct the correlations between the TRA/TPB constructs for statistical artifacts across 72 studies, and path analyses…

A Meta-Analytic Review of the Common-Sense Model of Illness Representations
A meta-analysis of empirical studies ( N = 45) adopting Leventhal, Meyer and Nerenz's (1980) Common Sense Model (CSM) of illness representations is presented. The average corrected intercorrelation matrix for the sample of studies showed that the CSM illness cognition dimensions of consequences, control/cure, identity and timeline followed a logical pattern supporting their construct and discriminant validity across illness types. A content analy…
The Processes by Which Perceived Autonomy Support in Physical Education Promotes Leisure-Time Physical Activity Intentions and Behavior
The trans-contextual model proposes that young people's perceived autonomy support in physical education will affect their perceived locus of causality, intentions, and physical activity behavior in leisure time. High school students completed measures of perceived autonomy support and perceived locus of causality in physical education. One week later, participants' perceived locus of causality and constructs from the theory of planned behavior w…
Physical Self-Perceptions in Adolescence
This study examines the generalizability of the form, structural parameters, and latent means of a hierarchical multidimensional model of physical self-perceptions in adolescents from three cultures.

A structural equation model that hypothesized a hierarchical structure with global self-esteem …
Physical Self-Concept in Adolescence
This study tests the generalizability of the factor pattern, structural parameters, and latent mean structure of a multidimensional, hierarchical model of physical self-concept in adolescents across gender and grade. A children's version of the Physical Self-Perception Profile (C-PSPP) was administered to seventh-, eighth- and ninth-grade high school students ( N= 2,969). Two a priori models were proposed: a confirmatory factor-analytic model tha…
The influences of intrinsic motivation on execution of social behaviour within the theory of planned behaviour
The present study examined the utility of two forms of measurement of intrinsic motivation in increasing the predictive validity of the theory of planned behaviour. Self-report questionnaires were administered to school pupils (n = 174), University students (n = 129) and adults (n = 157). The data were analysed using confirmatory factor analysis and regression analysis. Confirmatory analysis supported discriminant validity between Forms A and B m…
Intrinsic Motivation and Self-Determination in Exercise and Sport
The world of exercise and sport is fascinated by motivation and the factors that drive it. It's no wonder researchers both in and out of the sport domain will enthusiastically welcome Intrinsic Motivation and Self-Determination in Exercise and Sport. Motivation is central to many social psychological theories that aim to explain behavior, including self-determination theory, one of the most influential theories of human motivation developed in th…

Effects of an intervention based on self-determination theory on self-reported leisure-time physical activity participation
Based on self-determination theory, the present study developed and evaluated the utility a school-based intervention to change pupils' physical activity intentions and self-reported leisure-time physical activity behaviour. The study evaluated utility of the intervention to promote physical activity participation over a 5-week interval of time. A cluster randomised design targeting 215 pupils from 10 schools with schools as the unit of randomisa…
Integrating the theory of planned behaviour and self‐determination theory in health behaviour
Purpose A meta‐analysis of studies integrating the theory of planned behaviour (TPB) and self‐determination theory (SDT) in health contexts is presented. The analysis aimed to provide cumulative empirical support for a motivational sequence in which self‐determined motivation from SDT predicts the proximal predictors of intentions and behaviour from the TPB. Methods A literature search identified 36 integrated studies providing 45 tests of effect…
Sustaining a positive altruistic identity in humanitarian aid work
This case study explores the interpersonal and intrapersonal experiences of a single individual who spent more than 35 years in humanitarian aid work. Using interpretative phenomenological analysis, one superordinate theme, altruistic identity (AI), emerges. On return home following a humanitarian mission, AI requires (a) strong perception of empathic validation for intimate reintegration and (b) self-acceptance of personal involvement. However, …

Never the twain shall meet? Quantitative psychological researchers’ perspectives on qualitative research
The aim of this article was to provide a quantitative researchers’ perspective on qualitative research applied to sport and exercise psychology. Specifically, we aimed to identify some of the ‘problems’ that researchers adopting a predominantly quantitative, ‘natural science’ approach to psychological phenomena in psychology have with qualitative approaches. In addition, we also identified, as researchers from a predominantly background, the meri…
The Importance of Importance in the Physical Self
This study tested James's theoretical assumption that the importance people attribute to different physical self-domains, in combination with perceived competence in those domains, influences higher order self-concepts. Data from four large samples (total N=1,831) from Sweden, Great Britain, Portugal, and Turkey were analyzed. A new version of an instrument, the Physical Self-Perception Profile-Revised (PSPP-R), was used to measure perceived comp…
A minimum price per unit of alcohol
There was little evidence to suggest that people would support the introduction of a minimum price per unit of alcohol policy. Scepticism about the effectiveness of the policy is likely to represent the most significant barrier to public support. Findings also suggest that clearer educational messages are needed to dispel misconceptions regarding the effectiveness of the policy and the introduction of the policy as part of a package of government…
