Description of intervention(s) / exposure
This is a trial with one experimental treatment condition where, following an initial assessment session in which participants are also taught basic calming techniques, each participant serves as their own 2-week wait list control then engages EMDR therapy for treatment of symptoms consistent with PTSD. The minimal calming intervention includes teaching calm breathing, safe place, and identifying coping resources. EMDR therapy will utilise eye-movements as the dual attention task during desensitisation of trauma memories. EMDR therapy will follow the standard EMDR protocol outlined by Shapiro (2001). EMDR therapy is administered in 60-90 minute individual sessions on alternate days with one of 2 EMDR therapists and a translator over 17 days. Participants will receive a maximum of 10 active treatment sessions. The duration of the study for any participant will conclude after a 3 month follow-up assessment following the end of therapy, resulting in a participation duration of approximately 4 months.

Comparator / control treatment
Wait list controlled. The duration of the waitlist period for each participant is 2 weeks.
Experimental conditions: (1) EMDR-with eye movements whereby participants act as their own control.
There is not a seperate control group.
Note: The wiatlist control consisted of a minimal stabilization intervention. Whereby, following the initial asessment, and prior to the two week waitlist period, basic calming techniques were taught to each participant (safe place and calm breathing). Participants supports and coping resources were also identified. Att he end of the initial assessment it took approximately 20mins to teach calming techniques, and participants were encouraged to use the techniques should they feel distressed during the waitlist period.

Uncontrolled

Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be treatment seeking Timorese males and females attending a NGO health service in Timor Leste. Following an initial face-to-face assessment interview to assess trauma history and current symptoms consistent with PTSD, and at the end of the assessment participants are also taught 2 calming techniques and their coping resources are identified, participants will then be placed on a 2 week wait list for EMDR treatment. Post-treatment and 3 month follow-up assessment will be conducted by a second Timorese health worker/contact person involved in the study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
All participants were allocated to EMDR therapy after thier 2 week wait list period.
