Effects of Goal Type and Reinforcement Type on Self-Reported Domain-Specific Walking Among Inactive Adults: 2×2 Factorial Randomized Controlled Trial

Accordingly, there remains a need to develop potent interventions capable of producing an impact on a broader scale. Mobile health (m Health) technology provides a platform for increasing intervention reach and quickly tailoring content in response to an individual’s behavior and preferences, but it requires evidence-based and scalable interventions to improve population health.

A Culturally Relevant Smartphone-Delivered Physical Activity Intervention for African American Women: Development and Initial Usability Tests of Smart Walk

These diaries were then provided to the research team at a given time interval for review (ie, once a week or once a month) and to formulate feedback on participant progress. Current technology allows this process to occur in real time with less participant burden through the use of commercially available activity monitors, which can be viewed as a closer match to theoretical ideals.

Effects of Bluetooth-Enabled Desk Ellipticals on Office Work Performance: Rationale, Design, and Protocol for a Randomized Trial With Overweight and Obese Adults

Therefore, a more comprehensive assessment of work performance during office-based pedaling is warranted. Previous office-based desk pedaling studies demonstrated small declines in employees’ pedaling activity over time [13,29,31,32], suggesting a need for greater reinforcement of pedaling activity.

Evaluating the Carrot Rewards App, a Population-Level Incentive-Based Intervention Promoting Step Counts Across Two Canadian Provinces: Quasi-Experimental Study

A more thorough review of how these theories complement each other in a financial health incentive context is presented elsewhere [39]. Briefly, timely in-app notifications (“Congrats! You have achieved your 6600 daily step goal!”)

Tutorial for Using Control Systems Engineering to Optimize Adaptive Mobile Health Interventions

An open loop experiment is “open loop” because the intervention options that are provided to a person are specified a priori and, thus, a person’s responsivity to the intervention options are not taken into account when selecting future intervention options. When a person’s data are taken into account to adjust support, this is called a closed loop experiment.

The Walking Interventions Through Texting (WalkIT) Trial: Rationale, Design, and Protocol for a Factorial Randomized Controlled Trial of Adaptive Interventions for Overweight and Obese, Inactive Adults

Focused recruitment of minority populations was conducted through a free online social group advertisement. Interested participants were directed to a secure online survey system (Qualtrics, LLC) for a pre-screening step, where they found a brief description of the study and completed the eligibility survey. Those determined to be eligible at pre-screening were contacted via phone and email for a telephone follow-up screening.

A Text Message-Based Intervention for Weight Loss: Randomized Controlled Trial

It has been known for over 30 years that a 10% reduction in weight corresponds to an approximate 20% reduction in coronary disease incidence, whereas a 10% increase in weight is associated with a 30% increase in incidence [7]. Thus, rather than requiring dramatic levels of weight loss, expert consensus is that lifestyle interventions that promote modest levels of sustained weight loss are likely to confer substantial health benefits [8].
