Exploring the links between various traumatic experiences and ICD-11 PTSD and Complex PTSD: A cross-sectional study

Area of Science:

• Psychiatry
• Psychology
• Trauma Studies

Background:

• The International Classification of Diseases (ICD-11) introduced distinct diagnoses for Posttraumatic Stress Disorder (PTSD) and Complex Posttraumatic Stress Disorder (CPTSD).
• Both PTSD and CPTSD require exposure to a traumatic event for diagnosis.
• Understanding the differential impact of various trauma types is crucial for accurate diagnosis.

Purpose of the Study:

• To investigate if specific types of traumatic experiences differentiate risk for ICD-11 PTSD versus CPTSD.
• To identify unique trauma predictors for each disorder.

Main Methods:

• A sample of 158 trauma-exposed adults was assessed.
• The Life Events Checklist-Revised (LEC-R) measured trauma exposure.
• The International Trauma Questionnaire (ITQ) assessed risk for PTSD and CPTSD.
• Multinomial logistic regression analyzed trauma types as predictors.

Main Results:

• Childhood or adult sexual abuse was associated with both PTSD and CPTSD.
• Unwanted sexual experiences and childhood physical abuse predicted CPTSD over PTSD.
• Exposure to natural disasters predicted PTSD over CPTSD.

Conclusions:

• Specific traumatic events, including sexual trauma, childhood physical abuse, and natural disasters, may help differentiate between PTSD and CPTSD risk.
• Further research is needed to explore the nuanced relationship between trauma characteristics and diagnostic outcomes.
