Main types of stressors related to PTSD.

Stressor Related to PTSD	Study	Findings
Sexual assault	Creamer et al. (2001) [46]	Most common traumatic stressor resulting in PTSD, accounting for 50% of cases; among these, rape was the most common form of sexual assault
War and combat	Hoge et al. (2008) [49]	Severity of physical injury is correlated to the earlier development of PTSD in soldiers returning from deployment
Child abuse and neglect	Koenen, Widom (2009) [56]	Childhood physical and sexual abuse, as well as neglect significantly increase the risk of developing PTSD. Females tend to have an increased risk
Medical illness	Edmondson et al. (2012) [58]	The rate of PTSD among ACS patients was 12%, while it was 24% for those who stayed in the ICU. Additionally, PTSD patients were more likely to not adhere to their medications
Disasters	Ahern et al. (2002) [68]	Female gender, low social support, history of previous trauma, and direct exposure to the disaster were all factors that correlated with PTSD initiation after the disaster
