Different Types of Traumatic Exposure Link Divergently to PTSD and CPTSD

Area of Science:

• Psychology
• Trauma Studies
• Public Health

Background:

• War-related events can cause significant psychological distress.
• Understanding the nuances of traumatic exposure is crucial for mental health outcomes.
• The October 7 attack and subsequent Israel-Hamas War provide a critical context for studying trauma.

Purpose of the Study:

• To profile individuals at risk after war-related trauma.
• To examine the differential impact of direct vs. indirect and distal vs. proximal traumatic exposure on PTSD and CPTSD.
• To investigate the role of social media exposure in trauma response.

Main Methods:

• A cohort of 582 Israeli citizens reported on traumatic exposure, PTSD, and CPTSD.
• Data collected a year before and two months after the October 7 attack.
• Logistic and multinomial regressions analyzed associations between exposure types and PTSD/CPTSD.

Main Results:

• Both direct and indirect, distal and proximal exposures were linked to PTSD.
• Indirect exposure (familial Holocaust background, media) was associated with higher PTSD risk.
• Direct exposure (lifetime, war) and media exposure were linked to elevated CPTSD risk.

Conclusions:

• Different types of traumatic exposure are associated with distinct posttraumatic outcomes.
• Indirect exposure, particularly disturbing media, may lead to severe reactions akin to direct trauma.
• This highlights the need for tailored interventions based on exposure type.
