But if you are asked, "What is your evidence behind your screening tool?" Ask "What is the evidence behind yours?"(for example for pediatric bipolar).
You will find that the DSM is a group of academic doctors getting together to decide these symptoms mean this diagnosis. The evidence is slim at best. They can give not genetic, epigenetic, demographic or you name it ... answers....However an association called "The Directors of State Mental Health Providers asked them to put Developmental Trauma Disorder in the DSM - 5 (it has the most evidence base as it is associated with the National Child Traumatic Stress Network and they worked overtime to get this dx in - only problem is -- it encompasses so many trauma associated diagnoses and so the tx would be trauma focused therapy - no drugs ---). So no dx.
The evidence base behind the association between childhood adversity and severe adverse mental, physical, and societal outcomes is clear----- (You don't have to have 5 million ACE studies to come to the conclusion that there is a significant link)... and that society will save in term of money spent and human suffering......
however beware.... if ACEs were to become a reality...a business that makes lots of money on drugs and a profession who learned only to give out drugs may fight back and they fight HARD.....
They have the money and the resources to do so...
I did cancer research before medical school... we studied a cancer drug that is now making big money for a drug company... I am not 100% sure but I do believe most of the grant funding came from the NCI (National Cancer Institute) little from the drug company but that company is currently reaping the profits of my and our lab's work
