Non-verbal cognitive development, learning, and symptoms of PTSD in 3- to 6-year-old refugee children.

As IQ tests are commonly used as key assessment method, we address the question whether our commonly used standardized IQ tests are appropriate for children from families of diverse cultures and different educational levels in a refugee population. We examined 109 refugee children aged 3-7 years (M = 5.10 years, SD = 1.25) with the "Kaufman Assessment Battery for Children " (KABC-II; Kaufmann & Kaufmann, 2015) on a language-free scale (Scale of Intellectual Functioning, SIF) and learning performance (subtest Atlantis). With a non-verbal IQ of 81.5 (SD = 18.01), the population mean of the refugee children is more than one standard deviation lower than the mean of the German norm population. Standardized scores follow the normal distribution and are not correlated to any of the assessed markers of adversity (flight duration, time spent in Germany, child PTSD in parent rating, parental symptom load, and parental education level).Conclusion: The interpretation of IQ test results for refugee children should be done cautiously as results may underestimate their cognitive capacity. Environmental factors, such as high illiteracy among parents in this study, the lack of institutional education of children and high lifetime stress, may explain our findings.Trial registration: DRKS00021150. What is Known: • There is a high pervasiveness for the use of standardized IQ tests in the German health and education system to determine eligibility for special education and social services. What is New: • Refugee children score significantly lower than German children in a language-free IQ test. As results are normally distributed and not correlated to any of the assessed markers of adversity, the low scores in the refugee group might be due to missing formal education.

Survival states as indicators of learning performance and biological stress in refugee children: a cross-sectional study with a comparison group.

BACKGROUND: Our goal was to accurately detect young children at risk for long-term psychiatric disturbances after potentially traumatic experiences in the course of relocation. In addition to detailed assessment of parent-rated parent and child symptomatology, we focused on disruptive behaviors in the education environment summarized as survival states, as these frequently lead to clinical referral. METHODS: We screened 52 refugee children aged 3-7 (M = 5.14 years, SD = 1.17) for symptoms of Posttraumatic Stress Disorder (PTSD) with the Child and Adolescent Trauma Screening (CATS) in parent rating. The parents' mental health was assessed using the Refugee Health Screener (RHS-15). Furthermore, the child's educators were asked to evaluate the pathological survival states of the child and we made a general assessment of the children's symptoms with the Strengths and Difficulties Questionnaire (SDQ) rated by parents and educators. Children in the refugee sample completed a working memory learning task (Subtest Atlantis from the Kaufmann Assessment Battery for Children, KABC-II) and delivered saliva samples for testing of the cortisol level. RESULTS: The parental rating of their child's PTSD symptoms was significantly related to their own mental well-being (r = .50, p < .001). Children with survival states in educator ratings exhibited weaker learning performance (F = 3.49, p < .05) and higher evening cortisol levels (U = 113, z = - 1.7, p < .05, one-tailed). CONCLUSIONS: Survival states are promising indicators for children's learning performance and distress level complementary to parent rating of child PTSD, which is highly intercorrelated with the parents' own symptom load.
