Optimization of a group‐based intervention for people living with severe obesity ( <scp>PROGROUP</scp> ): Understanding fidelity to delivery and the patient experience
The success of group-based interventions relies on the facilitator addressing the group's needs and creating conditions for a shared social identity to develop. Assessment of fidelity to the manual content and core function of PROGROUP enabled identification of components needing refinement, incorporating both facilitator and patient perspectives. The assessment and optimization process offer a blueprint for evaluating other group-based interventions.
