Hi Susan,
I concur with Gail's suggestion about the ACEs in Education group, and the resources listed there.
Since the World Health Organization (WHO) has an ACE screening tool (the WHO ACE International Questionaire - available in 100+ languages on the WHO website, with a User's Guide)-with more than 10 ACE 'categories'; and: In 2000, I attended a "Grand Rounds" continuing education session at [then Dartmouth, now] Geisel Medical School, where an Epidemiologist reported: "52% of Detroit Metropolitan Area Schoolchildren met the [then] DSM-IV criteria for PTSD" [similar numbers are now being reported for Philadelphia, Baltimore, and Atlanta Schoolchildren-last I'd heard]; Might it help your Graduate Students, to ascertain if ACEs 'pre-dispose' one to develop PTSD [I'm told some US Military Recruiters are now using an ACE score to determine if Recruits are 'pre-disposed' to PTSD], ...... and if using the WHO ACE screening tool [it has more than the 8 or 10 types of ACEs the CDC/ Kaiser ACE study did]. Also taking the Resilience questionaire, too, might better prepare them for later "Clinical Supervision", or utilizing your existing classes may avail them the "Athenian Theater" benefit, too.
As an afterthought, the [September 2014] TED Talk video by Pediatrician Nadine Burke Harris about ACEs may be an appropriate introduction to ACEs, for those students (and for communities where the students later present)...
