Simon, thanks for your replies
i) most treatment studies don't like at the effects of therapies on comorbid disorders --- hence EMDR will look at anxiety/trauma, but not the comorbid psychiatric disorder -- ethical / political problems
ii) I live in New Zealand and hence don't keep up to date with English (or Canadian) newspapers so am particularly appreciative of your Q on Boarding School Syndrome -- you could well be right, but I think, but haven't yet inquired into, experience of other forms of abuse / travel -- suspect he may have been sexually abused -- Americans would call it straight PTSD. I'm a fan of Acceptance and Commitment Therapy, and Behavioral Psychotherapy, and will be introducing patient to that combination -- lots of studies of ACT and PTSD -- Great example of the benefits of ACEsC being such a diverse world of valuable contributors(ions).
Emotional abuse -- client suffered pneumonia age 12 -- got no visitors while in hospital, including no notifications / well wishes from parents.
Client can display positive feelings, but won't admit to many negative feelings apart from loneliness.
