Trauma and Posttraumatic Stress in Unaccompanied Young Refugees During Their Flight: A Longitudinal Cross-Country Study

Background: Unaccompanied young refugees (UYRs) constitute an especially vulnerable population who report high rates of trauma and mental health problems. There is a significant gap in the literature on trauma and symptoms of posttraumatic stress disorder (PTSD) in UYRs who are still on the move and live in precarious circumstances such as refugee camps. This study therefore aimed at investigating pre- and peri-migration trauma of UYRs, longitudinal trajectories of PTSD, and the impact of gender, trauma, and daily stressors on PTSD over time. Methods: This longitudinal, mixed-method, and multi-country study was conducted in various settings (e.g. refugee camps) across nine European countries. A representative and heterogeneous sample of N = 187 UYRs (78.4% male) from 29 different countries was assessed via interviews at 3 time-points during a period of 27 months. Data was analyzed via growth curve modelling.Results: Prevalence rates of traumatic experiences ranged between 29.5-91.9%. PTSD scores were high but significantly decreased over time (b = -0.98; p = .004). Females reported higher PTSD compared with males at baseline (p = .002), but gender did not influence the longitudinal trajectory of PTSD. Pre-migration trauma had a significant effect on PTSD at baseline (b = 0.48; p = .042). More daily stressors resulted in higher PTSD across time (b = 0.13-0.26; p ≤ .001). Conclusions: The number of traumatic events pre- and peri- migration, daily stressors and PTSD in this heterogeneous sample are to say the least alarming. Humanitarian and political assistance is urgently needed to curb the oftentimes life-threatening conditions UYRs face during their migration.
