Southeast Asia contains high numbers of traumatised populations arising from either natural disasters or interpersonal violence. Consequently, the need for empirically based trauma treatments, compromised by insufficiency in appropriately trained clinicians and mental health workers, makes the situation more challenging in addressing traumatic sequelae in local populations. In response, the humanitarian/ trauma capacity building organisation, Trauma Aid Germany, trained 37 therapists in psycho-traumatology, based on EMDR Therapy, which included trauma stabilisation techniques. This research analyses the impact of Trauma Stabilisation as a sole treatment intervention for Post-Traumatic Stress Disorder (PTSD) in adults. Each client was screened for PTSD utilising the Harvard Trauma Questionnaire - pre- and post-treatment. Analysis of the data considered only those interventions focussed on trauma stabilisation, including psychoeducation. Participants receiving trauma confrontation interventions were excluded from the data. Trauma stabilisation - as a sole treatment intervention, was highly effective in alleviating PTSD diagnoses. Results demonstrate PTSD symptoms were reduced in both clinical and sub-clinical trauma groups. The data set suggests trauma stabilisation, as a sole treatment intervention, was safe, effective, efficient and sufficient treatment intervention for PTSD. Furthermore, trauma stabilisation interventions have the advantage of being safe, flexible, and adaptable to the cultural and spiritual context in which they were are applied. The research findings also have implications regarding teaching and learning and the potential utilisation of paraprofessionals, and other allied health professionals in addressing the global burden of psychological trauma.
