Reduced Freezing in Posttraumatic Stress Disorder Patients while Watching Affective Pictures

Besides fight and flight responses, animals and humans may respond to threat with freezing, a response characterized by bradycardia and physical immobility. Risk assessment is proposed to be enhanced during freezing to promote optimal decision making. Indeed, healthy participants showed freezing-like responses to threat cues. Posttraumatic stress disorder (PTSD) patients are characterized by hypervigilance and increased threat responsiveness.

Loss of loved ones or home due to a disaster : effects over time on distress in immigrant ethnic minorities

Exposure to mass trauma may bring about increased sensitivity to new or ongoing stressors. It is unclear whether sensitivity to stress associated with ethnic minority/immigrant status may be affected by severe exposure to mass trauma.

Prolonged grief, depression, and posttraumatic stress in disaster-bereaved individuals : Latent class analysis

Background Hundreds of individuals lost one or more significant others in the MH17 plane crash in 2014 in Ukraine. The current study is the first to explore subgroups of disaster-bereaved individuals based on presence of psychopathology clusters. This may inform the development of diagnostic instruments and tailored interventions.

Mental health on the move : short review on migration and mental health

The first studies on migration and mental health focused primarily on immigration in the Unites States in the beginning of the 20th century. Higher levels of mental health problems or “insanity” were observed among migrants as compared to host populations. Selective migration of mentally ill people was understood to explain this difference. Although hypomanic traits such as impulsiveness, extraversion and risk seeking behaviour may seem to predispose individuals to emigrate, the so-called selective migration hypothesis has never been empirically supported.

Gender and Age Differences in Trauma and PTSD Among Dutch Treatment-Seeking Police Officers.

Little is known about how age and gender are associated with posttraumatic stress disorder (PTSD) symptoms and traumatic experiences in treatment-seeking police offers. In this study, we examined 967 diagnostic files of police officers seeking treatment for PTSD. Six hundred twelve (63%) of the referred police officers were diagnosed with PTSD (n = 560) or partial PTSD (n = 52). Police officers reported on average 19.5 different types of traumatic events (range 1-43). Those who experienced a greater variety of traumatic events suffered from more PTSD symptoms.

Predicting post‐traumatic stress disorder treatment response in refugees : Multilevel analysis

Abstract
Objectives
Given the recent peak in refugee numbers and refugees’ high odds of developing post-traumatic stress disorder (PTSD), finding ways to alleviate PTSD in refugees is of vital importance. However, there are major differences in PTSD treatment response between refugees, the determinants of which are largely unknown. This study aimed at improving PTSD treatment for adult refugees by identifying PTSD treatment response predictors.

Prevalence, correlates and treatment of nightmares in secondary mental healthcare

Nightmares are associated with psychopathology. The prevalence of nightmares in the general population is 2-5%. However, the impact of nightmares when comorbid mental disorders are present is unknown. We investigated the prevalence of nightmares in a population with diverse mental disorders.

The mechanisms that associate social capital with disaster mental health: a multilevel model

Many scholars have advocated that the time has come to provide empirical evidence of the mechanisms that associate community social capital with individual disaster mental health. For this purpose we conducted a study (n = 232) one year after a flood (2008) in Morpeth, a rural town in northern England. We selected posttraumatic stress as an indicator of disaster mental health. Our multilevel model shows that high community social capital is indirectly salutary for individual posttraumatic stress.
