Traumatic experiences can deeply affect mental health, leading to conditions like post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD). CPTSD includes symptoms like difficulty controlling emotions, negative self-perceptions, and relationship challenges, alongside traditional PTSD symptoms such as flashbacks and avoidance of reminders. Interestingly, trauma is also linked to psychosis symptoms, such as delusions and hearing voices. This study explored how CPTSD and psychosis symptoms are connected, using data from 747 adults in Montreal who had experienced trauma. Researchers analysed how different symptoms interacted in a network to identify key symptoms linking the conditions. They found that difficulties in calming down when upset acted as a bridge between trauma-related symptoms and psychosis symptoms. Additionally, hearing one’s own thoughts aloud was identified as a central symptom in the network. The study highlights the importance of addressing emotional regulation difficulties and auditory experiences in treating individuals with CPTSD and psychosis-like symptoms. These findings could help clinicians target key symptoms for better mental health outcomes. However, the study's findings may not apply to all populations due to its focus on a specific group from Montreal, and further research is needed to understand the cause-and-effect relationships.
