Bessel van der Kolk, in his most recent research on developmental impact of childhood trauma, writes:
“Childhood trauma, including abuse and neglect is probably the single most important public health challenge (we face)…a challenge that has the potential to be largely resolved by appropriate prevention and intervention” (van der Kolk, B. 2007 p.224).
Childhood trauma has both long term negative health outcomes, as well as generational transference of attitudes and behaviour. Hence, historical trauma transference across family and communal systems can result.
