Hi Dan, yes, there has been tremendous research in this area and it may be more nuanced and complex than the way the question is framed. Please check out the ACEs Connection Resource Center. Additionally, the CDC has a specific section on ACEs. Many resources can also be found online. Here is just one example: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4713310/
I hope this is helpful.
