Summary: The Birth Place Lab team developed and validated the Mothers Autonomy in Decision Making scale (MADM), a scale created to assess women’s experiences with maternity care. The MADM scale reflects person-driven priorities, and reliably assesses interactions with maternity providers related to a person’s ability to lead decision-making over the course of maternity care. The tool is being applied across 23 countries to evaluate quality of maternity care at the institutional, system and country levels and is a reliable and valid instrument, presently MADM version 1.0 is the most recent version and should be used for all new studies.
