Complex trauma, PTSD and complex PTSD in African refugees.

Area of Science:

• Psychiatry and Psychology
• Traumatic Stress Studies
• Refugee Mental Health

Background:

• The ICD-11 introduction of complex posttraumatic stress disorder (CPTSD) necessitates validity assessment in populations exposed to complex trauma (CT).
• Refugee populations frequently experience CT, defined as repeated, prolonged, interpersonal traumatic events, making them a critical group for study.

Purpose of the Study:

• To compare diagnoses of post-traumatic stress disorder (PTSD) using DSM-5 and ICD-11 criteria.
• To evaluate the discriminant validity of ICD-11 PTSD and CPTSD constructs in treatment-seeking refugees in Italy.

Main Methods:

• A sample of 120 treatment-seeking African refugees in Italy, all survivors of CT, were assessed.
• Participants were diagnosed with PTSD and CPTSD according to both DSM-5 and ICD-11 criteria.
• Latent class analysis was used to identify distinct diagnostic groups.

Main Results:

• Prevalence rates were 79% for DSM-5 PTSD, 38% for ICD-11 PTSD, and 30% for ICD-11 CPTSD.
• ICD-11 CPTSD items demonstrated high sensitivity and negative predictive power, but low specificity and positive predictive power.
• Latent class analysis identified separate PTSD and CPTSD groups; demographic and trauma variables did not predict group membership, but time in Italy correlated with symptom severity.

Conclusions:

• The findings support the discriminant validity of ICD-11 PTSD and CPTSD in refugees exposed to severe trauma.
• While time in a safe environment may alleviate post-traumatic symptoms, it does not appear to influence the development of CPTSD.
• Further research is required to identify specific vulnerability factors contributing to PTSD or CPTSD development in refugee populations.
