Role of childhood adversities and environmental sensitivity in the development of post-traumatic stress disorder in war-exposed Syrian refugee children and adolescents.

BACKGROUND: Increased post-traumatic stress disorder (PTSD) rates have been documented in children exposed to war. However, the contribution of childhood adversities and environmental sensitivity to children's responses to adversities and trauma are still far from settled.AimsTo evaluate the relative roles of war, childhood adversities and sensitivity in the genesis of PTSD. METHOD: Data on childhood adversities and sensitivity was collected from 549 Syrian refugee children in Lebanon. PTSD symptoms were assessed using the PTSD Reaction Index. RESULTS: Although childhood adversities, war events and sensitivity were all significantly related to PTSD in bivariate analyses, multivariate analyses showed that childhood adversities were the most important variable in predicting PTSD. The effect of war on PTSD was found to be dependent on the interplay between childhood adversities and sensitivity, and was most prominent in highly sensitive children with lower levels of adversities; in sensitive children experiencing high levels of adversities, the effects of war exposure on PTSD were less pronounced. CONCLUSIONS: When considering the effects of war on PTSD in refugee children, it is important to take account of the presence of other adversities as well as of children's sensitivity. Sensitive children may be more vulnerable to the negative effects of war exposure, but only in contexts that are characterised by low childhood adversities.Declaration of interestNone.

Childhood adversities and traumata in Lebanon: a national study.

BACKGROUND: The goal of this paper is to map the total occurrence and evaluate the risk of co-occurrence of childhood adversities (CA) and a wide variety of childhood traumatic events (including war) in a national sample. METHOD: The nationally representative sample included 2,857 respondents and the instrument used was the Composite International Diagnostic Interview which screened for all CAs and traumatic events. RESULTS: 27.9% experienced CAs; the most common were parental death and parental mental/substance use disorder. 70.6% experienced a war-related traumatic event during their lifetime, and around half of them (38.1%) experienced it below the age of 18 years. 51.3% of the subjects experienced a traumatic event not related to war during their lifetime, and 19.2% experienced it before the age of 18 years. Sexual abuse, being a refugee during war, and experiencing a natural disaster were associated with female gender. Having any CA was associated with active war exposure (OR: 4.2, CI: 2.0-8.6); war-related direct personal trauma (OR: 3.9, CI: 1.5-10.0); war-related trauma to others (OR: 2.4, CI: 1.3-4.4); non-war direct personal trauma (OR: 3.8, CI: 2.0-7.4); and any non-war childhood traumatic event (OR: 1.9, CI: 1.1-3.1). CONCLUSION: Childhood is awash with adversities and traumatic events that co-occur and should be measured simultaneously; otherwise, the effects of a subset of traumata or adversities could be wrongly thought to be the contributor to negative outcomes under study.
