Mindfulness-based interventions are increasingly utilized not only to enhance health and wellness in the face of disease and disorder but also to manage stress, anxiety, and daily worries. However, their application has been limited among diverse populations. A Special Section of Mindfulness highlights emerging research focused on inclusivity, diversity, equity, and accessibility in mindfulness-based interventions, as well as studies on child, parent, and family well-being. These studies provide valuable insights into theoretical issues, the need for culturally tailored mindfulness interventions for specific groups, and how such programs can be developed organically and collaboratively among researchers, participants, and community partners. The emerging field of mindfulness research within the context of diversity can advance further if research decisions are guided by established scientific principles.
