The sharp rise over the past decade in young children's access to various forms of screen media (e.g., smartphones, tablets, TVs) has posed new and significant challenges to caregivers in managing children's use of this type of media. For caregivers of young children with externalizing behavior problems, managing children's time with screen media…

Kids SIP"smart"ER is a 6-month behavioral and health literacy intervention effective at reducing sugar-sweetened beverage (SSB) intake among middle school students and their caregivers in the rural Appalachian region. This exploratory mixed methods study utilized a convergent parallel design to assess participant acceptability of a…

Objectives: Digital interventions are increasingly used to support behaviour change. In the prevention of chronic work-related skin diseases, the sustainable implementation of appropriate skin protection behaviour following tertiary individual prevention is important. However, there exists no intervention to support the maintenance of these…

Background: There is little understanding of men's weight loss outcomes and behaviors in self-directed contexts, such as digital commercial mobile weight management programs. This is an especially pressing question given that men often express disinterest in weight management programs and it is unknown how that manifests in self-directed…

Objective: To evaluate the feasibility and acceptability of a theory-grounded, text message-based intervention targeting sedentary behaviour among university students. Design: Single-group repeated measures design. Setting: Post-secondary institution in British Columbia, Canada. Methods: Data concerning students' sedentary behaviour were collected…

Objective: To test the feasibility of a university health center-delivered smoking cessation intervention that adds a 6-week course of text messaging to brief advice and nicotine patch therapy. Participants: Young adult cigarette smokers (n = 40) from 2 universities from January 2015 to May 2016. Methods: Randomized controlled trial comparing…

Household members of diarrhea patients are at higher risk of developing diarrheal diseases (>100 times for cholera) than the general population during the 7 days after the diarrhea patient is admitted at a health facility. There is growing evidence demonstrating that theory-driven water, sanitation, and hygiene (WASH) interventions are likely…

Objective: To test the effectiveness of a text-message intervention to promote sleep hygiene to improve sleep in young adult college students. Participants: A convenience sample of undergraduate students from one Southwestern university (n = 96), 18-26 years old, recruited in August 2015. Methods: A 2-group pretest-posttest experimental design…

The purpose of the study was to examine the effectiveness of "efitbuddy," a theory-based smartphone application, on young adults' BMI, physical activity, and motivation across a 4-week intervention. Participants were a convenience sample of 312 (mean age = 19.4 ± 2.3 years) college students. A quasi-experimental design with the control…

Background: Unhealthy lifestyle habits developed during university years could continue into adulthood. Purpose: To analyze and map worldwide publications on physical activity among university students. Method: A pre-validated search strategy was used to find relevant articles in the Scopus database. The study period represented three decades…

Objective: Mobile health apps hold potential to support and reinforce positive health behaviours, especially among young people with chronic diseases like asthma that require continual self-management. We aimed to gain feedback from adolescents with asthma on two existing asthma self-management apps to guide the development of an evidence- and…

College is a time of transitioning as individuals move from the teenage years to adulthood. Accompanying this transition, there is a potential to establish lifelong behaviors such as a regular physical activity (PA) and exercise regimen, or a complete lack thereof, that can impact adulthood health. The current study included a convenience sample…

Introduction: Inadequate caregiving conditions interfere with successful health and development outcomes. Access to appropriate information can result in improved health and development outcomes in children. Health promotion text messaging, a primary mHealth strategy, has been implemented in various countries to reach communities where the…

Electronic games delivered via smartphones have the potential to become valuable tools in HIV prevention in high-prevalence and low-resource international settings. To ground theoretical elaboration around novel mHealth interventions in contextual realities, it is important to understand the mechanisms of their effects as perceived by local…

Few interventions to promote physical activity (PA) adapt dynamically to changes in individuals' behavior. Interventions targeting determinants of behavior are linked with increased effectiveness and should reflect changes in behavior over time. This article describes the application of two frameworks to assist the development of an adaptive…
