Objectives <p>The objective of this research was to map the Sussex Mindfulness Meditation (SuMMed) model to US adults, thereby demonstrating its utility for future researchers. Additionally, the research explored engagement with meditation beyond what the model explicitly prescribes, including with apps. This served as a means to offer potential refinements to the model and deepen our understanding of meditation habit formation.</p> Method <p>This research used a representative survey of 2000 adults in the USA. The sample was rigorously recruited using the Ipsos KnowledgePanel.</p> Results <p>In mapping the SuMMed model, 69.7%, 19.1%, 2.3%, and 9.0% of US adults were in the Pre-Intention, Preparation, Action, and Maintenance Stages of meditation habit formation, respectively. In the Preparation stage, 34.5% planned to meditate within the next 7&#xa0;days, while only 21.9% intended to start a regular meditation practice within the next month. Additionally, people with less mature meditation practices were more likely to intend to use meditation apps, compared to established meditators.</p> Conclusions <p>The SuMMed model offers a useful way to understand meditation among US adults and future researchers should leverage it confidently. However, people often tried meditation out of curiosity and appeared to distinguish between trying and experimenting with meditation, versus having a practice. Given this, we recommend a modification to the Preparation stage of the SuMMed model to integrate meditation trial and experimentation. Additionally, meditation apps may be more useful to support early meditation practices, compared to established practices.</p> Preregistration <p>This study was not preregistered.</p>
