Abstract
This article describes development of a theory to guide nurses promoting perinatal weight self-management behaviors. The Coaching for Childbearing Health (CoaCH) Model was developed through synthesis of the Individual and Family Self-Management Theory with Transitions Theory, following Walker and Avant's process of theory synthesis. Qualitative data were integrated to provide perinatal context. The CoaCH Model is composed of context factors that shape a nurse coaching intervention, supporting patients' self-management efforts. Sustained engagement in weight self-management behaviors will impact the long-term health of both the birthing person and the child. This model is a testable framework for future perinatal health promotion efforts.
