When Fear Remains: The Development and Maintenance of Posttraumatic Stress Disorder

Research Of Dr Jennifer Dawson


"I understand that the expense of academic journal articles precludes many communities from having access to current trauma research. By publishing my thesis in this forum I aim to promote equitable access to peer – reviewed research, and to contribute to the global community’s development of an informed, effective approach to trauma.


I gratefully acknowledge the support of Macquarie University and in particular Dr Judi Homewood and Dr John Franklin for their assistance with this research. My special thanks to Dr Malcolm Macnaughtan from Seeker Wireless for providing technical assistance with my laboratory equipment and, more importantly, a safe space for me to organise diverse concepts and large visions."

Dr Jennifer A. Dawson, 2008
