  • Project Details

    Phoenix Australia - Centre for Posttraumatic Mental Health, (Phoenix) in collaboration with Austin Health Veterans Psychiatry Unit, conducted an early pilot trial of imagery rehearsal (IR) therapy in 2001. The success of this trial has led to investigation of the nature of the phenomenon of posttraumatic dreams – whether they are better understood and treated as intrusive symptoms of PTSD or as dreams that have become stuck in a cycle of chronic repetition.

    The efficacy of IR has continued to be investigated, with around 20 trials internationally. Unfortunately, much of the research continues to be low quality. Phoenix is currently collaborating on a randomised controlled trial of CBT for insomnia versus CBT for insomnia + IR for U.S. veterans returning from Iraq and Afghanistan with Philadelphia VA, Department of Psychiatry at University of Pennsylvania and Department of Psychiatry at Yale School of Medicine. Future research will investigate whether IR is more or less effective for different types of posttraumatic nightmares, including those that replay traumatic experience versus those that are symbolic, and those that are more like daytime intrusions of PTSD versus those that are more like normal dreams. This research will have important treatment implications.

    Phoenix is also collaborating with Austin Health Sleep Clinic and Post Trauma Recovery Service (PTRS) to undertake an investigation of the sleep factors that underpin posttraumatic nightmares, using ambulatory polsomnography. Key questions to be addressed in this research include: Are posttraumatic nightmares restricted to REM sleep or can they occur across other stages of sleep?; Are posttraumatic nightmares associated with sleep disorders such as obstructive sleep apnoea? Does dream phenomenology differ depending on the stage of sleep and/or the presence of underlying sleep disorder?
