Emotion regulation and PTSD risk among internally displaced Sudanese children: a community-based cross-sectional study

Résumé fourni par la source

Internally displaced children are among the most vulnerable populations affected by armed conflict, often enduring psychological trauma that may lead to emotional dysregulation and post-traumatic stress disorder [PTSD]. This study aimed to assess emotion regulation among internally displaced children in Sudan and evaluate its relationship with PTSD symptoms. A cross-sectional, community-based study was conducted between July and September 2024, including 703 internally displaced children aged 8–18 across five Sudanese cities. Data were collected through structured caregiver-reported and child-reported instruments, including the Children’s Emotional Management Scales [CEMS] and the Children’s Revised Impact of Event Scale [CRIES-8]. Associations between emotion regulation subscales and PTSD symptoms were statistically analyzed using Wilcoxon Rank Sum, Welch’s Anova, and Chi-square tests, followed by multivariable logistic regression to identify independent predictors of PTSD. The prevalence of PTSD symptoms was 74.4%, with the highest rates observed in Atbara and Al-Gedaref states. In bivariate analysis, anger dysregulation was significantly associated with gender ( p = 0.002), and significantly lower among children with PTSD symptoms ( p = 0.007). In multivariable analysis, children whose mothers were free workers or unemployed had 4.6-fold and 3.3-fold higher odds of PTSD ( p < 0.001), respectively, compared to children of employed mothers. Children originally from outside Khartoum had 2.9-fold higher odds of PTSD ( p = 0.004), and those currently residing in Atbara and Gedaref had 3.1-fold ( p <0.001) and 2.8-fold ( p = 0.012) higher odds, respectively, compared to Port Sudan. Despite considerable emotional distress, children demonstrated relatively preserved coping strategies, especially in sadness regulation. This study reveals a high prevalence of PTSD symptoms among internally displaced Sudanese children, with emotional dysregulation and inhibition posing risks for long-term mental health. These findings highlight the urgent need for culturally sensitive, scalable mental health interventions that promote emotional expression and caregiver involvement. Integrating school- and community-based psychosocial support programs into humanitarian response frameworks in displacement settings is critical to mitigate long-term mental health consequences among affected children.
