Hi Emily,
I would suggest you post this request to ACEs in Pediatrics as well and also include if you have a particular age group you have in mind. You may have already searched on AAP. While this doesn't address stigma at all, there are links in here to resources for mental health: http://pediatrics.aappublicati...tent/138/3/e20161571
Also, the AAP has a Committee on Psychosocial Aspects of Child and Family Health.
Hope this all helps!
