Systematic search of Bayesian statistics in the field of psychotraumatology

In recent years there has been increased interest in Bayesian analysis in many disciplines  Bayesianmethods implement Bayes’ theorem, which states that prior beliefs are updated with data, and this process produces updated beliefs about model parameters.

The prior is based on how much information we believe we have preceding data collection, as well as how accurate we believe that information to be. Within Bayesian statistics, priors can come fromany source; for example, a meta-analysis, a previous study or, even, expert consensus.

Aberrant brain response after auditory deviance in PTSD compared to trauma controls : An EEG study.

Part of the symptomatology of post-traumatic stress disorder (PTSD) are alterations in arousal and reactivity which could be related to a maladaptive increase in the automated sensory change detection system of the brain. In the current EEG study we investigated whether the brain’s response to a simple auditory sensory change was altered in patients with PTSD relative to trauma-exposed matched controls who did not develop the disorder.

The role of clinical experience, diagnosis, and theoreticalorientation in the treatment of posttraumatic anddissociative disorders : A vignette and survey investigation

Controversy exists regarding the merits of exposure-based treatments for posttraumatic stress disorder (PTSD) versus a phased approach when prominent dissociative symptoms are present.

The first aim of this study was to examine the degree to which diagnosing dissociation in two traumatized patients' vignettes influenced clinicians' preference for phase-oriented treatment and whether clinicians' treatment experience contributed to their treatment preference.

Association between baseline psychological attributes and mental health outcomes after soldiers returned from deployment

Background:

Psychological health is vital for effective employees, especially in stressful occupations like military and public safety sectors. Yet, until recently little empirical work has made the link  between requisite psychological resources and important mental health outcomes across time in those sectors. In this study we explore the association between 14 baseline psychological health attributes (such as adaptability, coping ability, optimism) and mental health outcomes following exposure to combat deployment.

 

Methods:

Cross-lagged associations between posttraumatic stress symptoms and coping self-efficacy in long-term recovery : A four-wave comparative study

RATIONALE:

Trauma-related coping self-efficacy (CSE) - in brief, the perceived ability to cope with the aftermath of a traumatic event - has been shown to affect psychological outcomes. A previous study showed that CSE affects subsequent PTSS levels, but not vice versa among a sample exposed 0-6 months ago.

OBJECTIVE:

Formin 2 links neuropsychiatric phenotypes at young age to an increased risk for dementia

Age-associated memory decline is due to variable combinations of genetic and environmental risk factors. How these risk factors interact to drive disease onset is currently unknown.

Here we begin to elucidate the mechanisms by which post-traumatic stress disorder (PTSD) at a young age contributes to an increased risk to develop dementia at old age.

We show that the actin nucleator Formin 2 (Fmn2) is deregulated in PTSD and in Alzheimer’s disease (AD) patients.

An overview of posttraumatic stress disorder genetic studies by analyzing and integrating genetic data into genetic database PTSDgene

Posttraumatic stress disorder (PTSD) is a debilitating psychiatric syndrome with complex etiology. Studies aiming to explore genetic susceptibility and environmental triggers of PTSD have been increasing. However, the results are limited and highly heterogeneous. To understand the genetic study status of PTSD and explore more reliable candidates, we obtained 105 PTSD related genetic studies by comprehensively literature searching and filtering 1762 studies. Detailed phenotype and sample information for each study and association results for each genetic marker were extracted.

Screening for trauma-related symptoms via a smartphone app : The validity of Smart Assessment on your Mobile in referred police officers

To facilitate easily accessible screening for trauma-related symptoms, a web-based application called Smart Assessment on your Mobile (SAM) was developed. In this study, we examined whether SAM was able to accurately identify posttraumatic stress disorder (PTSD) and depression in adults.

The assessment of psychopathology among traumatized refugees : measurement invariance of the Harvard Trauma Questionnaire and the Hopkins Symptom Checklist-25 across five linguistic groups

Background: Questionnaires are widely used to assess the mental health status of refugees, whereas their construct validity largely remains unexplored.

Objective: This study examined the construct validity of two widely-used instruments for the assessment of PTSD symptoms (Harvard Trauma Questionnaire [HTQ]; 16 items) and symptoms of anxiety and depression (Hopkins Symptom Check list-25 [HSCL-25]; 25 items) among Dutch and refugee patients with different linguistic backgrounds.

Grief following homicidal loss

Homicidally bereaved individuals have to deal with the notion that their loved one

is deliberately taken from them: the death is caused by the premeditated action of

another individual, most often unexpected. While the psychological consequences

for the people left behind are assumed to be great, few studies systematically

examined psychopathology following homicidal bereavement. The aim of this

dissertation was threefold. First of all, adaptation to homicidal loss was examined,
