Reviews

“This volume is highly recommended to clinicians and researchers as an excellent resource of contemporary thinking in understanding some of the many complex ways that individuals respond to traumatic experiences” 
- Pamela R. Fuller, Fronteir Psychological Associates

PTD includes outstanding contributions from international experts and provides a comprehensive view of its topics, particularly with respect to conceptual and research issues. The editors have interspersed throughout the book parentheses leading the reader to other related chapters, but a summarizing contribution would have been welcome. That small qualm notwithstanding, PTD is essential reading for anyone wanting to understand how trauma, dissociation, and psychosis both  converge and diverge.
