The eleventh edition of the () is under development and current proposals include major changes to trauma-related psychiatric diagnoses, including a heavily restricted definition of posttraumatic stress disorder (PTSD) and the addition of complex PTSD (CPTSD). We aimed to test the postulates of CPTSD in samples of 2695 community participants and 323 trauma-exposed military veterans. CPTSD prevalence estimates were 0.6% and 13% in the community and veteran samples, respectively; one-quarter to one-half of those with PTSD met criteria for CPTSD. There were no differences in trauma exposure across diagnoses. A factor mixture model with two latent dimensional variables and four latent classes provided the best fit in both samples: classes differed by their level of symptom severity but did not differ as a function of the proposed PTSD versus CPTSD diagnoses. These findings should raise concerns about the distinctions between CPTSD and PTSD proposed for .

Positionality statements: Intersectional considerations for rehabilitation psychology.

Introduction: Positionality statements accompanying peer-reviewed publications are increasingly being implemented in academic journals across many disciplines, including psychology. These statements serve as transparent, public acknowledgments of the authors' identities, which can offer valuable insight into the authors' work in the context of their lived experiences and potential biases. However, journal editors and associated staff risk harm by uniformly adopting a policy on positionality statements without consideration of the unintended consequences of implementing such practices.

This study explored the usage of occupational therapy treatment with psychologically injured public safety personnel (PSP) from Ontario, Canada. We used a descriptive quantitative approach with summary data provided by the Workplace Safety and Insurance Board (WSIB) of Ontario documenting occupation therapy (OT) treatment of psychologically injured PSP who had an approved WSIB Mental Stress Injury Program (MSIP) claim between 2017 and 2021. Variables examined included demographics, career type, injury type, and return to work (RTW) outcomes.

Repeated traumatic brain injury has grown in importance as sports-related injuries have increased. Repetitive mild TBI (rmTBI) increases the risk of developing neurodegenerative diseases such as Alzheimer's and Parkinson's diseases, as well as chronic comorbidities like PTSD, depression, substance abuse and neuroendocrine functions. However, no effective therapeutic strategies have been reported for the effective management of TBI.

An increasing number of studies have been investigating the co-occurrence of posttraumatic symptoms and dissociation in trauma-exposed samples. As traumatized refugees are particularly susceptible to developing posttraumatic stress disorder (PTSD), the aim of this study was to investigate the relationship between PTSD and dissociation in a traumatized refugee sample. Cross-sectional data from a clinical refugee sample ( = 526) were collected.
