Background
Regular physical activity (PA) is associated with positive health outcomes; however, rates of regular PA are low. Positive psychology interventions are efficacious in other health contexts and may be useful for promoting regular PA.
Purpose
Phased development and pilot/feasibility testing of a positive psychology intervention to promote...
Background
Continuous glucose monitoring (CGM) holds potential as a precision public health intervention, offering personalised insights into how diet and physical activity affect glucose levels. Nevertheless, the efficacy of using CGM in populations with and without diabetes to support behaviour change and behaviour-driven outcomes remains unclear...
Background
Amidst the escalating prevalence of glucose-related chronic diseases, the advancements, potential uses, and growing accessibility of continuous glucose monitors (CGM) have piqued the interest of healthcare providers, consumers, and health behaviour researchers. Yet, there is a paucity of literature characterising the use of CGM in behavi...
Research on positive affect (PA) and negative affect (NA) is often guided by the rotational variant of the circumplex model of affect (RCMA). According to the RCMA, PA and NA are posited to be orthogonal, with PA ranging from the union of positive valence and high activation (e.g., excited) to the union of negative valence and low activation (e.g.,...
2024 SBM Annual Meeting Abstracts Supplement. Ann Behav Med. 2024:58(Suppl 1);S56.
Background
More than half (55%) of Latina women do not meet aerobic physical activity (PA) guidelines, and frequently cite time, childcare, and transportation as barriers to PA. In addition to linguistic adaptations for this population, successful PA interventions for Latina women addressed these barriers through remote intervention delivery approa...

Current U.S. guidelines recommend that adults obtain 150 min per week of moderate intensity physical activity (PA), 75 min of vigorous intensity PA, or some equivalent combination. However, less than half of U.S. adults reach this goal, with the proportion even smaller among adults with overweight or obesity. Moreover, regular PA declines after age...
Background
Engaging in regular physical activity (PA) is particularly important among individuals with depression, who are at heightened risk for a host of negative health outcomes. However, people with depression are 50% less likely to meet national guidelines for PA and face unique barriers to PA adherence, including lower distress tolerance and...
Objective
This study sought to integrate the NIH Science of Behaviour Change (SOBC) measures repository comprising measures of putative mechanisms with mechanisms of action (MoA) identified by the Human Behaviour‐Change Project (HBCP).
Design
Participants were 30 international experts recruited from professional networks and societies. In three an...
Background
Cognition-based theories dominate physical activity (PA) research, and many include a construct broadly defined as “beliefs about the consequences of behavior” (e.g., outcome expectancies, perceived benefits) hereafter referred to as perceived consequences.
Purpose
With the quantity of available research on this topic, it is important t...
Cognition-based theories dominate physical activity (PA) research, and many include a construct broadly defined as ‘beliefs about the consequences of behavior’ (e.g. outcome expectancies, perceived benefits) hereafter referred to as perceived consequences. With the quantity of available research on this topic, it is important to examine whether the...
Background
Many global health challenges may be targeted by changing people’s behaviour. Behaviours including cigarette smoking, physical inactivity and alcohol misuse, as well as certain dietary behaviours, contribute to deaths and disability by increasing the risk of cancers, cardiovascular diseases and diabetes. Interventions have been designed...
Perceptions of the physical and social environment have been shown to be predictive of physical activity (PA) behavior. However, the mechanisms of this association have not been examined. Affective response to PA was examined as a putative mediator of the association between perceptions of the PA environment and subsequent PA behavior. As part of a...
Background:
Behavioral interventions typically include multiple behavior change techniques (BCTs). The theory informing the selection of BCTs for an intervention may be stated explicitly or remain unreported, thus impeding the identification of links between theory and behavior change outcomes.
Purpose:
This study aimed to identify groups of BCT...
Researchers, practitioners, and policymakers develop interventions to change behavior based on their understanding of how behavior change techniques (BCTs) impact the determinants of behavior. A transparent, systematic, and accessible method of linking BCTs with the processes through which they change behavior (i.e., their mechanisms of action [MoA...
Background: To efficiently search, compare, test and integrate behaviour change theories, they need to be specified in a way that is clear, consistent and computable. An ontology-based modelling system (OBMS) has previously been shown to be able to represent five commonly used theories in this way. We aimed to assess whether the OBMS could be appli...

Objective: The present study tested the hypothesis that the effect of self-paced exercise on adherence to exercise programs is more pronounced with increasing age. Method: Fifty-nine low-active overweight adults (18-65 years) were encouraged to walk 30 to 60 min/day and randomized to either self-paced (n = 30) or prescribed moderate-intensity (n =...

Objective:
To pilot test two low-cost and thus financially sustainable incentive programs to promote physical activity (PA) among low-active adults in a community setting.
Method:
In a three-arm randomized controlled trial the effects of small monetary incentives (cash incentives $1/day; n = 25) were compared to charitable donations (donation $1...
Use of natural language to represent behaviour-change theories has resulted in lack of clarity and consistency, hindering comparison, integration, development and use. This paper describes development of a formal system for representing behaviour-change theories that aims to improve clarity and consistency. A given theory is represented in terms of...
Over the past seventy years, biomedical and epidemiological research has shown that regular physical activity (PA) is critical for physical and mental health. Despite this knowledge, physical inactivity is the fourth leading risk factor for global mortality, accounting for 9% (5.3 million) of premature deaths annually. We suggest this mismatch betw...
Background: To advance understanding of intervention effects, and improve theory development, a methodology for linking behavior change techniques (BCTs) to the processes through which they change behavior (i.e. their mechanisms of action (MoAs)) is required. Purpose: To triangulate evidence for hypothesized BCT-MoA links obtained in previous liter...
BACKGROUND: Understanding the mechanisms through which behaviour change techniques (BCTs) can modify behaviour is important for the development and evaluation of effective behavioural interventions. To advance the field, we require a shared knowledge of the mechanisms of action (MoAs) through which BCTs may operate when influencing behaviour. PURPO...
