Physical Activity Research with Apps and Wearable Trackers
Klein Buendel Scientist, Dr. Kayla Nuss, was a presenter or co-author on four panels, posters, and presentations at the 44th Annual Sessions and Meeting of the Society of Behavioral Medicine in Phoenix, Arizona on April 26-29, 2023. The presentations highlighted research Dr. Nuss conducted as a Post-doctoral Fellow at the University of Victoria in Canada before joining Klein Buendel as a Scientist in 2022.
Presentation 1: Poster Session
“Examining the Effect of Daily Social Media Use of Physical Activity Behaviors: A Daily Diary Study”
Presenters: Ms. Rebecca Coulter, Dr. Sam Liu, and Dr. Kayla Nuss
Previous studies have assessed the effects of health-related social media use on physical activity; however the evidence remains mixed. Currently, little is known about how daily social media use influences daily physical activity behavior. Understanding the influence of social media use on physical activity behavior may help design future interventions. The objective of this study was to examine whether the daily consumption of health-related social media content is associated with daily physical activity behaviors. Results provided evidence that viewing health-related social media content can influence daily physical activity behavior – specifically , exercise intensity. The authors suggested that future studies should focus on within-person variations in behavior based on social media use.
Presentation 2: Symposium 1
“Contextual and Situational Motivation for Physical Activity in Wearable Activity Tracker Users: A Daily Diary Study”
Presenters: Ms. Rebecca Coulter, Dr. Sam Liu, and Dr. Kayla Nuss
Wearable activity trackers (WAT) were developed to support physical activity engagement but little is known about how WAT users are motivated for physical activity. The presenters have identified distinct motivational profiles among WAT users; but no study has assessed the relationship between contextual and situational motivation for physical activity. To evaluate this relationship, intensive daily survey methodology is needed. Understanding the relationship between contextual and situational motivation for physical activity is critical to improve the effectiveness of WAT. The objectives of the study were to: (1) evaluate the feasibility of collecting day-level situational motivation for physical activity using a customized mobile app made by a no-code app development platform; and 2) describe two levels of motivation (contextual and situational) in WAT users using the hierarchical model of motivation. The presenters hypothesized that they would identify distinct motivational profiles and that those profiles would predict differing levels of situational motivation. Collecting situational motivation for physical activity was feasible using a no-code mobile platform. WAT users vary in their contextual motivational profile for physical activity and these predict some types of situational motivation. They suggested that future research should further investigate physical activity motivation in WAT users to identify intervention opportunities.
Presentation 3: Symposium 2
“Implementing Mobile Health Interventions and Observational Studies Using a No-code App Development Platform”
Presenters: Dr. Denver Brown, Dr. Sam Liu, Dr. Kayla Nuss, and Ms. Amanda Willms
Mobile health (mHealth) technology holds tremendous potential to deliver behavior health interventions and understand human behavior. However, a challenge facing researchers when conducting mHealth research is the resources required to develop and maintain mHealth apps. Specifically, a no-code mHealth research app development platform may enable researchers with no previous software programming skills to create apps through a graphical user interface. In this symposium, presenters discussed how a no-code app development platform, was created and used to co-design and implement physical activity mHealth interventions and conduct longitudinal observational studies to understand physical activity behavior. The first presenter provided an overview of the no-code mHealth research platform and discussed its development and usability testing. The second presenter discussed how the platform was used to co-design adaptive mHealth physical activity interventions. Dr. Nuss discussed how the platform was used to implement a daily diary study to examine changes in situational motivation for physical activity based on contextual motivational profile in current wearable activity tracker users over a 14-day period. The final presenter discussed how the platform was used conduct a longitudinal feasibility study examining the influence that first-year roommates have on one another’s device-measured physical activity behavior during the transition to university which included weekly surveys to capture dyadic relations.
Presentation 4: Paper Session
“Reflecting on Physical Activity across Two Years of the COVID-19 Pandemic: Predictors if Intention-Behavior Profiles”
Presenter: Dr. Ryan Rhodes
Co-authors: Dr. Sam Liu, Dr. Kayla Nuss, and Dr. Wuyou Sui
The COVD-19 Pandemic has affected how many people engage in regular moderate-to-vigorous intensity physical activity (MVPA). Understanding the correlates of various motivational and behavioral profiles is important to producing effective interventions. The purpose of this study was to predict current and dynamic (across two years of the COVID-19 Pandemic) intention and MVPA profiles using the multi-process action control (M-PAC) framework. Few participants increased MVPA across the pandemic and dynamic patterns of intention-MVPA profiles by pre-pandemic MVPA showed the presence of two at risk groups (relapsed non-intenders relapsed unsuccessful intenders) who have relapsed in MVPA. Collectively, the findings support the joint promotion of reflective regulatory and reflexive processes in the choice of behavior change techniques to promote post-pandemic MVPA intention and behavior.
