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

Abstract

BackgroundIncreased 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.MethodData on childhood adversities and sensitivity was collected from 549 Syrian refugee children in Lebanon. PTSD symptoms were assessed using the PTSD Reaction Index.ResultsAlthough 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.ConclusionsWhen 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.

A socio-ecological analysis of risk, protective and promotive factors for the mental health of Burundian refugee children living in refugee camps

“…As expected, higher exposure to violence related to war, within the family, and in the community was associated with higher levels of PTSD symptoms and internalizing problems. This is consistent with a large body of evidence documenting the detrimental mental health impact of traumatic experiences [2,56], child maltreatment [20,40,57] and community violence [27,28] for refugee and non-refugee children and adolescents across various socioeconomic and cultural settings. Studies conducted within a socio-ecological framework have shown how violence on more distal ecological levels, e.g., structural and community violence, adversely affects children's adjustment both directly and indirectly by increasing violence within the more proximal family context [58][59][60].…”

Trauma-Related Psychopathology in Iraqi Refugee Youth Resettled in the United States, and Comparison With an Ethnically Similar Refugee Sample: A Cross-Sectional Study

“…Additionally, while youth from both countries had experienced warzone exposure and forced migration, we did not assess other potential adverse events youth may have been exposed to, which may have varied between samples resulting in the observed differences in posttraumatic stress symptoms. The presence of other adversities should be taken into account in both the clinical and research setting when working with refugee youth, as the effects of warzone exposure and forced migration on trauma-related psychopathology may be dependent on exposure to other adversities (Karam et al, 2019).…”

Implementation Evaluation of the Mother‐Child Education Program Among Refugee and Other Vulnerable Communities in Lebanon

“…We were interested in documenting the process of implementing MOCEP—a program that targets parenting practices and knowledge with the aim to boost children's holistic development and school readiness—in Lebanon. This is important because exposure to adversity during early childhood has been shown to be predictive of post‐traumatic stress disorder among Syrian refugee children living in Lebanon (Karam et al., ). Caregiver support has been identified as a necessary, core component of humanitarian responses, yet parenting programs in these contexts are scarce (Cobham & Newnham, ).…”
