Background: Prospective research on the development and trajectory of PTSD symptoms after a traumatic event is crucial for assessment and early intervention. Further, examining predictors of PTSD pathology provides a better conceptualization of the temporal course of PTSD in trauma victims.
Methods: The present study examined PTSD symptom severity in individuals presenting to the emergency department (ED) following a traumatic event. Participants (N = 147) were assessed at four timepoints: 2-weeks, 3-months, between 6 and 9 months, and 12-months after ED admission. Growth curve modeling was conducted to examine changes in PTSD symptom severity over time. Age, sex, state anxiety, trait anxiety, emotion dysregulation, depression, and trauma type (motor vehicle accident [MVA] and assault), and PTSD diagnosis were included as covariates in the model.
Results: Results demonstrated that baseline PTSD symptom severity was positively associated with severity of depression and state (but not trait) anxiety, emotion dysregulation, and PTSD diagnosis. Results also revealed significant associations with PTSD symptom changes over time; greater state anxiety and depression symptoms at baseline were associated with steeper declines in PTSD symptoms over time.
Limitations: Data were collected at only four timepoints over the course of 12-months. Results may be different with more measurement points over longer periods and inclusion of pre-, peri- and post-trauma risk factors.
Conclusions: Results illustrate the relevance of assessing state anxiety, depression, and emotion dysregulation in following trauma victims for trauma-related psychopathology over the course of time to alleviate the negative impact of the same.

Aim: This research aimed to comprehensively explore the impact of diverse challenges encountered by older adults on the development of post-traumatic stress disorder (PTSD). It delved into how these effects vary depending on individuals' levels of trust in authority and medical professionals, providing a nuanced understanding of the interplay between external challenges, personal trust, and mental health outcomes in the older population.
Background: The COVID-19 pandemic has imposed significant hardships, particularly on the ageing population, with potential psychological repercussions such as PTSD.
Objective: Cannabis has become more available in Canada since its legalization in 2018. Many individuals who use cannabis also use alcohol (co-use), which can be used either at the same time such that their effects overlap (simultaneous use) or at different times (concurrent use). Though studies have identified predictors of co-use relative to single-substance use, less is known about the predictors of specific types of co-use.

Rationale: Psychedelic-assisted therapy is increasingly applied within mental health treatment.
Objectives: This study focused on factors moderating changes in the acute and long-term effects of an individual psilocybin-assisted program on depression, anxiety, PTSD and personality structures by including demographic factors, subjective experience and degree of mystical type experiences during the dosing, as well as emotional breakthrough and personal growth after the program.
Methods: At baseline, 1 week and 3 months after the psilocybin program participants completed the Generalized Anxiety Disorder Assessment (GAD-7), Patient Health Questionnaire (PHQ-9), PTSD Checklist for DSM-5 (PCL-5) and NEO Five-Factor Inventory-3 (NEO-FFI-3).

On 13-14 April 2024, Iran launched ∼300 drones and missiles at Israel, in an unprecedented attack. As most studies examine the effects of trauma months or years later, less is known about its effects days later. To fill this gap, this study gauged the population response, five days after the attack.
