Objective: We aimed to assess whether peritraumatic threat experienced during a period of armed conflict predicted subsequent depression symptoms.
Method: Ninety-six Israeli civilians provided real-time reports of exposure to rocket warning sirens and subjective sense of threat, twice daily for 30 days, during the 2014 Israel-Gaza conflict. Depression symptoms were reported 2 months after the conflict. Mixed-effects models were used to estimate peritraumatic threat levels and peritraumatic threat reactivity (within-person elevations in threat following siren exposure). These were then assessed as predictors of depression symptoms at 2 months in an adjusted regression model.
Results: Individual peritraumatic threat level, but not peritraumatic threat reactivity, was a significant predictor of 2 months depression symptoms, even after controlling for baseline depression symptoms.
Conclusions: The findings imply that in situations of ongoing exposure, screening for perceived levels of peritraumatic threat might be useful in identifying those at risk for developing subsequent depression symptoms.

Article Synopsis
- This study investigates how early social support after trauma affects PTSD symptoms over time and explores specific brain regions involved in this process, such as the amygdala and ventromedial prefrontal cortex.
- Using data from 315 participants in the AURORA study, researchers measured PTSD symptoms and perceived emotional support at multiple time points, while also conducting neuroimaging two weeks post-trauma.
- The results show that early emotional support is linked to changes in white matter connectivity between key brain areas, but it also highlighted unexpected increased threat reactivity in the default mode network, suggesting complex neural pathways in response to social threats.
Predicting DSM-5 PTSD symptomatology 6 months to 2 years after burn: The role of early psychological risk factors.

Background: Major burn injuries may have long-term mental health consequences, such as posttraumatic stress disorder (PTSD). This study extended prior work to investigate DSM-5 PTSD symptoms at 6 months, 1 year, and 2 years post-burn as well as the contribution of two sets of early psychological risk factors to DSM-5 PTSD symptoms: Established PTSD risk factors (prior adjustment problems, past trauma, perception of life threat, peritraumatic emotions and dissociation) and theory-derived cognitive factors (negative appraisals of the trauma and its sequelae, memory disorganization, trauma-related rumination, and thought suppression).
Method: The current study recruited a sample of 118 adult burn patients (75.
Peritraumatic dissociation and posttraumatic stress symptoms: the moderating role of perceived threat.

Although peritraumatic dissociation (PD) is viewed as a risk factor for posttraumatic stress disorder (PTSD), prospective studies taking into account other well-known risk factors for PTSD have been scarce, and the exploration of potential moderators within the relations between PD and PTSD has been lacking. Filling this gap, this prospective study explored the moderating role of perceived threat within the relations between PD and PTSD, above and beyond age, gender, education, and early trauma-related symptoms. A convenience sample of 200 Israeli civilians filled out self-report questionnaires during the peritraumatic phase (T1) and one to two months after the posttraumatic phase (T2) of being exposed to rocket attacks.

Background: Post-traumatic stress disorder (PTSD) following traumatic childbirth may undermine maternal and infant health, but screening for maternal childbirth-related PTSD (CB-PTSD) remains lacking. Acute emotional distress in response to a traumatic experience strongly associates with PTSD. The Peritraumatic Distress Inventory (PDI) assesses acute distress in non-postpartum individuals, but its use to classify women likely to endorse CB-PTSD is unknown.

The purpose of the study was to assess the prevalence rates of anxiety, depression, and posttraumatic stress disorder (PTSD) outcomes among teachers (N = 8,167) exposed to Hurricane Maria in Puerto Rico. The findings indicate that the rates of likely significant symptoms of anxiety, depression, and PTSD were 13.1%, 8.
