BACKGROUND Many patients with Posttraumatic Stress Disorder (PTSD) feel overwhelmed in situations with high levels of sensory input, as in crowded situations with complex sensory characteristics. These difficulties might be related to subtle sensory processing deficits similar to those that have been found for sounds in electrophysiological studies. (More)
BACKGROUND While emotion dysregulation represents an important mechanism underpinning psychological responses to trauma, little research has investigated this in refugees. In the current study, we examined the mediating role of emotion dysregulation in the relationship between refugee experiences (trauma and living difficulties) and psychological outcomes.(More)
Comorbid posttraumatic stress disorder (PTSD) and depression is common in refugee groups; however, little is known about the predictors and correlates of comorbidity in treatment-seeking refugees. Participants in this study were 134 refugees resettled in Switzerland. Most participants were from Turkey, Iran, and Sri Lanka, and 92.7% had been exposed to(More)
Although posttraumatic stress disorder (PTSD) is associated with a variety of structural and functional brain changes, the molecular pathophysiological mechanisms underlying these macroscopic alterations are unknown. Recent studies support the existence of an altered excitation-inhibition balance in PTSD. Further, there is preliminary evidence from(More)
BACKGROUND The construct of complex posttraumatic stress disorder (CPTSD) has attracted much research attention in previous years, however it has not been systematically evaluated in individuals exposed to persecution and displacement. Given that CPTSD has been proposed as a diagnostic category in the ICD-11, it is important that it be examined in refugee(More)
BACKGROUND Refugees have been shown to present high prevalence rates of trauma-related mental disorders. Despite their psychological impairment, they are expected to meet high functional requirements in terms of social integration into, and financial independence from, the host society. METHODS This cross-sectional study examined the relationship of(More)
BACKGROUND While there is a considerable amount of literature addressing consequences of trauma in veterans and holocaust survivors, war and postwar civilian populations, particularly children, are still understudied. Evidence regarding intergenerational effects of trauma in families is inconsistent. OBJECTIVE To shed light on intergenerational aspects of(More)
BACKGROUND Most research on refugee mental health has focused on posttraumatic stress disorder (PTSD). Besides PTSD, however, traumatised refugees are often burdened by comorbid somatic and psychiatric conditions, as well as postmigration living difficulties (PMLD). It is unclear how these conditions interfere with presentation and treatment of PTSD. (More)
BACKGROUND Prevalence rates of child maltreatment (CM) can differ substantially between countries and ethnicities. Reasons, however, are complex and not sufficiently understood. METHOD This epidemiological study examined prevalence and risk factors of various types of CM in a population-based representative sample of native and immigrant adolescents in(More)
We are writing in response to the Letter to the Editor by De Jongh and colleagues regarding our article ‘The factor structure of complex posttraumatic stress disorder in traumatized refugees’ (Nickerson et al., 2016). The authors raise several queries about the methodology employed in our study, asserting that ‘there were a number of flaws that we consider(More)
