Article
Self-monitoring applications (apps) are being increasingly integrated into diabetes prevention programs; however, more research is needed to understand how individuals engage with self-monitoring apps, what leads to sustained use, and whether these apps translate to improved physical activity over time. This brief report explored (1) participant en...
Article
Background Low-carbohydrate ketogenic diets are a viable method to lose weight that have regained popularity in recent years. Technology in the form of mobile health (mHealth) apps allows for scalable and remote delivery of such dietary interventions and are increasingly being used by the general population without direct medical supervision. Howev...

Objective To determine whether a Mediterranean-style ketogenic diet mobile health application (app) with breath acetone biofeedback is superior to a calorie-restricted low-fat diet app in promoting weight loss. Methods Participants (N = 155) with overweight/obesity (mean±SD: 41±11 y, BMI = 34±5 kg/m², 71% female) were randomized to one of the inte...
Article
Objective The purpose of this study was to examine self-regulatory efficacy (SRE) as an explanatory mediator of high-intensity interval training (HIIT) versus moderate-intensity continuous training (MICT) interventions in relation to physical activity levels over 6- and 12-months after condition assignment. Methods Two mediation models were run. T...

Lay Summary Making changes to one’s physical activity and diet can reduce future risk of developing type 2 diabetes. That being said, making life-long changes to complex behaviors such as diet or physical activity is easier said than done. Text messages can be used to improve long-term diet and physical activity changes; however, it can be difficul...
Article
Background: Mobile health (mHealth) prompts (e.g., text messaging, push notifications) are a commonly used technique within behaviour change interventions to prompt or cue a specific behaviour. Such prompts are being increasingly integrated into diabetes prevention programs (DPPs). While mHealth prompts provide a convenient and cost-effective way...
Article
More than 350 million people are living with prediabetes. Preventing type 2 diabetes (T2D) progression can reduce morbidity, mortality and health-care costs. Interventions can support people with diet and physical activity behaviour changes; however, many interventions are university-based, posing barriers (e.g. accessibility, limited reach and mai...
Article
The purpose of this secondary analysis study was to examine the affective and social cognitive responses to low-volume high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) over a progressive two-week supervised intervention for individuals at risk of type 2 diabetes. Ninety-nine adults that were low-active and o...
Article
Purpose: Self-regulatory efficacy (SRE) is a psychological resource necessary for cardiac rehabilitation (CR) exercise adoption and maintenance. A 2008 review of self-efficacy for CR exercise identified the need for more high-quality research on SRE. The present review had 4 purposes: (a) to review the characteristics of empirical SRE and CR exerc...
Article
Objectives Diabetes rates in the British Columbia (B.C.) Interior are rising more rapidly compared to the rest of Canada while diabetes service provision is limited within this region. The purposes of this paper were (1) to identify characteristics of diabetes service delivery and (2) to co-develop community-university diabetes research projects to...

Background Obesity and being overweight are major contributing factors for many diseases. Calorie restricted diets often fail to result in sustained long-term weight loss. Very low–carbohydrate, high-fat ketogenic diets have been suggested to have superior metabolic and weight loss effects. Keyto is a low-cost, highly scalable mobile health (mHealt...
Article
Background: Multiple sclerosis (MS) is a chronic disabling disease of the central nervous system which impairs muscular function and limits individuals' ability to carry out everyday activities requiring mobility. People with MS frequently exhibit mobility problems (i.e., slower walking speed, shorter strides). General exercise training (e.g., resi...

Background: Free-living adherence to high-intensity interval training (HIIT) has not been adequately tested. This randomized trial examined changes in cardiorespiratory fitness (CRF) and accelerometer-measured purposeful physical activity over 12 months of free-living HIIT versus moderate-intensity continuous training (MICT). Methods: Ninety-nin...
Article
BackgroundA number of mobile health (mHealth) apps exist that focus specifically on promoting exercise behavior. To increase user engagement, prompts, such as text messages, emails, or push notifications, are often used. To date, little research has been done to understand whether, and for how long, these prompts influence exercise behavior. Object...
Article
Objectives Exercise-related cognitive errors (ECEs) represent a negative lens that distorts individuals’ view of exercise. Such thinking can inhibit individuals’ behaviour change efforts. Reframing is an evidence-based counselling strategy used to help individuals evaluate the evidence for and against their biased thoughts. Reframing is commonly us...

Purpose: High-intensity interval training (HIIT) may lead to superior cardiometabolic improvements when compared to moderate-intensity continuous training (MICT). However, adherence to HIIT requires examination. The purpose of this pilot study was to examine moderate-to-vigorous physical activity (MVPA) adherence 24 weeks following a brief counsel...
Article

Background: Cardiac rehabilitation (CR) exercise therapy facilitates patient recovery and better health following a cardiovascular event. However, post-CR adherence to self-managed (SM)-exercise is suboptimal. Part of this problem may be participants' view of CR staff as mainly responsible for help and program structure. Does post-CR exercise adhe...
Article
Exercise-related cognitive errors reflect biased processing of exercise-relevant information. The purpose of this study was to examine whether differences existed between individuals reporting low and high exercise-related cognitive errors on information processed about a relevant exercise decision-making situation. In all, 138 adults completed an...
Article
Objective Cognitive errors (CEs) reflect individuals' biased evaluations of context-relevant information. In the exercise domain, a valid form of exercise CE assessment is needed. The Exercise-related Cognitive Errors Questionnaire (E-CEQ) was developed to determine to what extent adults make cognitive errors regarding exercise decisions. The purpo...
Article
In this paper, we argue that the social influence of the group is a supportive medium for older adult thriving. To promote the physical well-being aspect of thriving, we discuss groups as one means of offering social support. We present a specific model of physical activity intervention (i.e., group-mediated cognitive behavioral intervention) that...
Article
This study examined psychological differences between individuals (1) with varying perceptions of their exercise adherence pattern and (2) who do and do not make exercise-related cognitive errors. A total of 364 adults completed an exercise pattern and cognitive errors questionnaire. Individuals perceiving themselves as consistent exercisers report...
