To be exact, the claim from the book is except for severe PTSD, there is little influence, and in case of PTSD the healing works the same way for adults as for children (and possibly slightly better in children) - so “childhood” trauma is not in any way “special” compared to adult traumas.
As for evidence, why don’t you just go and read the book itself? Reading that chapter is on the order of 20 minutes of easy reading. Sorry, but I have better things to do than repeat what is already written elsewhere.
