Abstract
Background
Using regulatory focus theory, an intervention of daily weight loss-sustaining messages was developed and tested for acceptability, feasibility, and efficacy on helping people sustain weight loss.Methods
Participants (n = 120) were randomized to a promotion, prevention, or an attention-control text message group after completion of a weight loss program. Participants completed baseline assessments, and reported their weight at 1 and 3 months postbaseline.Results
Participants found the message content and intervention acceptable and valuable. A minimum of one message per day delivered at approximately 8:00 am was deemed the optimal delivery time and frequency. The sustained weight loss rate at month 3 for the control, promotion, and prevention groups was 90%, 95%, and 100%, respectively. Medium-to-large effects were observed for the promotion and prevention groups at month 1 and for prevention at month 3 relative to controls. The mean weight loss for promotion and prevention was 15 pounds, compared with 10 in the controls at month 3.Conclusion
A clinically significant decrease in mean weight, higher rate of sustained weight loss, and medium-to-large effects on sustained weight loss occurred in the promotion and prevention interventions. Tools such as this text message-based intervention that are constructed and guided by evidence-based content and theoretical constructs show promise in helping people sustain healthy behaviors that can lead to improved health outcomes.Type

Ryan Shaw
Ryan Shaw serves as the Chief Nurse Innovation Officer for Duke University Health System. By leveraging technology and evidence-based practices, he identifies opportunities to empower nurses to thrive as changemakers, addressing healthcare delivery challenges, improving patient outcomes, and enhancing efficiency.
In his faculty role at the Duke University School of Nursing, he leads research teams driving digital transformation in healthcare. His work has been supported by organizations such as the U.S. National Institutes of Health (NIH) and the National Science Foundation (NSF), among others. He is passionate about mentoring students to become the next generation of health scientists and clinicians.
Hayden Barry Bosworth
Dr. Bosworth is a health services researcher and Deputy Director of the Center of Innovation to Accelerate Discovery and Practice Transformation (ADAPT) at the Durham VA Medical Center. He is also Vice Chair of Education and Professor of Population Health Sciences. He is also a Professor of Medicine, Psychiatry, and Nursing at Duke University Medical Center and Adjunct Professor in Health Policy and Administration at the School of Public Health at the University of North Carolina at Chapel Hill. His research interests comprise three overarching areas of research: 1) clinical research that provides knowledge for improving patients’ treatment adherence and self-management in chronic care; 2) translation research to improve access to quality of care; and 3) eliminate health care disparities.
Dr. Bosworth is the recipient of an American Heart Association established investigator award, the 2013 VA Undersecretary Award for Outstanding Achievement in Health Services Research (The annual award is the highest honor for VA health services researchers), and a VA Senior Career Scientist Award. In terms of self-management, Dr. Bosworth has expertise developing interventions to improve health behaviors related to hypertension, coronary artery disease, and depression, and has been developing and implementing tailored patient interventions to reduce the burden of other chronic diseases. These trials focus on motivating individuals to initiate health behaviors and sustaining them long term and use members of the healthcare team, particularly pharmacists and nurses. He has been the Principal Investigator of over 30 trials resulting in over 400 peer reviewed publications and four books. This work has been or is being implemented in multiple arenas including Medicaid of North Carolina, private payers, The United Kingdom National Health System Direct, Kaiser Health care system, and the Veterans Affairs.
Areas of Expertise: Health Behavior, Health Services Research, Implementation Science, Health Measurement, and Health Policy
Isaac Marcelo Lipkus
Research Interests
Dr. Lipkus is interested in how risk perceptions, attitudinal, and dispositional variable (e.g., belief in a world) are related to modifying lifestyle behaviors such the prevention and detection of cancer, tobacco use, and physical activity.
Linda Lindsey Davis
My research interests are grounded in my early experiences as an adult nurse practitioner and are around elder care,family stress, coping and adaptation, and methods and measures for clinical research around those issues.
Constance Margaret Johnson
Dr. Johnson is an Associate Professor with tenure and a health informatician with interdisciplinary training in nursing and health informatics, and is the Faculty Coordinator of the Systems Programs at the Duke University School of Nursing. She has a secondary appointment in the Department of Community and Family Medicine in the Duke University School of Medicine and is an adjunct associate professor at the University of Texas at Houston Health Science Center, School of Biomedical Informatics.
