The rate of weight gain is highest immediately after cessation of a structured weight-loss program. Thus, effective interventions are needed that can successfully be used following a structured weight-loss program to sustain weight loss and prevent relapse. Due to low cost, ubiquity, and ease of use, healthcare communicated through mobile technology, or “mHealth”, may be able to serve as an effective medium to reach a large number of people to facilitate weight loss behaviors. Short message service (SMS) is easy to use, ubiquitous, affordable, and can target people directly where they are regardless of geographic location, socioeconomic status, or demographic factors.
Using the Behavior Change Process and regulatory focus theory, a recently completed mobile health (mHealth) intervention based upon evidence-based content and theoretical constructs leveraged SMS to automatically deliver messages to people who recently lost weight in attempt to help them sustain weight loss and prevent relapse. Participants will understand how informatics tools such as the mHealth intervention are constructed and guided by evidence-based content and how theoretical constructs can be used to help people sustain healthy behaviors that can lead to improved health outcomes.
