Fortieth anniversary of the International Marcé Society for Perinatal Mental Health: innovations in research, policy, and clinical care

Prompted by correspondence between Ian Brockington and Channi Kumar concerning a mother with a bonding disorder, the Marcé Society first met in 1980 to share information related to the emotional well-being of mothers (Glangeaud Freudenthal 2003). Biennial meetings have been held since to ensure regular information exchange, occurring even amidst the global Covid-19 pandemic. The 40th anniversary of the Society, celebrated at the virtual 2020 meeting, naturally prompts refection on accomplishments in research, policy, and clinical care of perinatal families. The publications included in this topical collection summarize key conference presentations, providing an archive of lessons learned and setting plans for future directions.
