In the UK, Hilary Kennedy has developed a wonderful therapeutic intervention for parents and children called Video Interaction Guidance or VIG. The website is 'videointeractionguidance.net' and it shows you how it works. It is totally in keeping with the ACE studies and with trauma-informed care as it is based on attachment research and promotes strengths by enabling parents to attune (and mentalize) with their Children and thereby heal the wounds resulting from trauma in both children and parents. As it happens it is now the official recommended treatment for adoptive families in the UK. It is both user- friendly and cost effective and therapists love it.
The reason why adopted traumatised children are resistant to the loving care of their adoptive parents is because they are paradoxically bonded by their traumatic attachment to their original abusive parent. VIG works so beautifully in maximizing the attunement capacity of parents that it appears to "melt' the traumatic attachment. I am currently doing clinical studies on adults suffering from the effects of Traumatic attachments to their caregivers who have problems with addiction and violence.
VIG training involves one week-end introduction and subsequent supervision of the work done in your jobs by trained VIG guides; this can be done partly on skype. They are now working in violent communities in Mexico and with addicted families in Ecuador as well as in many European countries. If interested get in touch with the VIG staff through their website.
