Posttraumatic stress disorder (PTSD) is a psychiatric disorder that can develop upon exposure to a traumatic event. While most people are able to recover promptly, others are at increased risk of developing PTSD. However, the exact underlying biological mechanisms of differential susceptibility are unknown. Identifying biomarkers of PTSD could assist in its diagnosis and facilitate treatment planning. Here, we identified serum microRNAs (miRNAs) of subjects that underwent a traumatic event and aimed to assess their potential to serve as diagnostic biomarkers of PTSD.

The loss of a loved one through death is usually followed by a funeral and engagement in various grief rituals. We examined the association between the evaluation of the  uneral, the use of grief rituals and grief reactions. Bereaved individuals from the Netherlands completed questionnaires, six months and three years post-loss (n=552/289).

Study Objectives: Sleep problems are a core feature of post-traumatic stress disorder (PTSD). The aim of this study was to find a robust objective measure for the
sleep disturbance in patients having PTSD.

Background: Families applying for asylum have often experienced multiple potentially traumatic events and continue to face stressors during their resettlement. Studies have indicated that traumatic events can negatively impact parenting behaviour and child development. A secondary preventive multi-family intervention programme, called Family Empowerment, was developed. Family Empowerment aims to strengthen parenting skills and prevent exacerbation of emotional problems in asylum-seeker families.

Five diagnostic criteria sets for pathological grief are currently used in research. Studies evaluating their performance indicate that it is not justified to generalise findings regarding prevalence rates and predictive validity across studies using different diagnostic criteria of pathological grief. We provide recommendations to move the bereavement field forward. 

Persistent complex bereavement (PCBD) was entered to DSM-5. No studies have yet examined the nature, prevalence, prognostic validity, and underlying mechanisms of PCBD symptom patterns in recently bereaved people. Knowledge on these issues could improve the early identification and treatment of disturbed grief. Latent class analysis was used to identify subgroups characterized by different PCBD symptom patterns among recently (≤6 months) bereaved adults (n = 476).

Purpose: Prior latent class analyses (LCA) have focused on people who were bereaved more than 6 months earlier. Research has yet to examine patterns and correlates of emotional responses in the frst few months of bereavement. We examined whether subgroups could be identifed among very recently (≤6 months) bereaved adults, based on their endorsement of symptoms of prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD), and depression.

The risk of posttraumatic stress disorder (PTSD) following trauma is heritable, but robust common variants have yet to be identified. In a multi-ethnic cohort including over 30,000 PTSD cases and 170,000 controls we conduct a genome-wide association study of PTSD. We demonstrate SNP-based heritability estimates of 5–20%, varying by sex. Three genome-wide significant loci are identified, 2 in European and 1 in African-ancestry analyses. Analyses stratified by sex implicate 3 additional loci in men.

Objective: Due to traumatic experiences and highly prevalent post-migration stressors, refugees are vulnerable for developing psychopathology. To date, research has mainly evaluated trauma-focused therapies, targeting post traumatic stresss symptoms. Treatments targeting post-migration stressors are relatively understudied. The present cohort study evaluated the potential effectiveness of 7ROSES, a transdiagnostic intervention that aims to increase self-efficacy among treatment-seeking refugees in dealing with postmigration stressors.

Background: To date, most studies on the mental health of refugees in Europe have focused on the prevalence and treatment of psychopathology. Little is known about those who illegally reside in the host country, referred to, in the Netherlands, as undocumented asylum seekers. There are indications that mental health and psychosocial problems are more prevalent in this group than among refugees in general, with unsatisfactory treatment outcomes.
