Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be treatment seeking patients attending the Traumatic Stress Clinic at Westmead Hospital. Participants will be randomly assigned according to a random numbers system administered by an individual who is independent of the study and who works at a site that is distant from the treatment center.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization will be conducted by a process of minimization stratified on gender, trauma type, and Posttraumatic Stress Disorder severity.
