Empirical data have challenged the unidimensionality of the Peritraumatic Dissociative Experiences Questionnaire (PDEQ), a widely used measure for peritraumatic dissociation. The aim of this study was to assess the factor structure of the PDEQ in 3 trauma-exposed samples: (a) trauma-exposed police officers (N = 219), (b) trauma-exposed civilians (N = 158), and (c) treatment-seeking trauma-exposed civilians (N = 185). Confirmatory factor analyses using measurement invariance testing supported a 2-factor structure (CFIs .96-.98, RMSEAs .07-.09), but excluded 2 of the original items.

AbstractPosttraumatic stress disorder (PTSD) affects a minority of trauma-exposed persons and is associated with significant impairment. This longitudinal study examined risk factors for PTSD. We tested whether the presence of injuries resulting from trauma exposure predicted the course of PTSD symptoms. In addition, we tested whether gender, trauma type, perceived life threat, and peritraumatic dissociation predicted the onset of PTSD symptoms. 236 trauma-exposed civilians were assessed for PTSD symptoms with a structured interview at four occasions during 6 months posttrauma.

BackgroundAlthough posttraumatic stress disorder (PTSD) has been associated with disturbances in verbal memory, studies examining executive functioning in PTSD show mixed results.MethodsA systematic review and meta-analysis were performed to compare executive functioning in patients with current PTSD and controls without any psychiatric disorder. Standard mean differences (SMD) in executive functioning scores were calculated using random-effects models. Covariates were added to examine whether differences exist between subgroups.ResultsAcross 18 studies, 1080 subjects were included.

Introduction:Previous literature has shown that multifaceted, interactive interventions may be the most effective way to train health and social care professionals. A Train-the-Trainer (TTT) model could incorporate all these components. We conducted a systematic review to determine the overall effectiveness and optimal delivery of TTT programs.Methods:We searched 15 databases. Reference lists and online resources were also screened. Studies with an objective follow-up measure collected over 1 week after the intervention were included.

AbstractObjectiveEvaluation of therapeutic touch (TT) in the nursing of burn patients, post hoc evaluation of the research process in a non-academic nursing setting.Methods38 burn patients received either TT or nursing presence. On admission, days 2, 5 and 10 of hospitalization, data were collected on anxiety for pain, salivary cortisol, and pain medication. Interviews with nurses were held concerning research in a non-academic setting.ResultsAnxiety for pain was more reduced on day 10 in the TT-group. The TT-group was prescribed less morphine on day 1 and 2.

There is now ample evidence from the preclinical and clinical fields that early life trauma has both dramatic and long-lasting effects on neurobiological systems and functions that are involved in different forms of psychopathology as well as on health in general. To date, a comprehensive review of the recent research on the effects of early and later life trauma is lacking. This book fills an obvious gap in academic and clinical literature by providing reviews which summarize and synthesize these findings.

BackgroundClinical and neurobiological evidence for a dissociative subtype of posttraumatic stress disorder (PTSD) has recently been documented. A dissociative subtype of PTSD is being considered for inclusion in the forthcoming Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5) to address the symptoms of depersonalization and derealization found among a subset of patients with PTSD.

BACKGROUND: The North Atlantic Treaty Organization (NATO) coalition forces remain heavily committed on combat operations overseas. Understanding the prevalence and characteristics of battlefield injury of coalition partners is vital to combat casualty care performance improvement. The aim of this systematic review was to evaluate the prevalence and characteristics of battle casualties from NATO coalition partners in Iraq and Afghanistan.

AbstractBackground: A lack of social support and recognition by the environment is one of the most consistent risk factors for posttraumatic stress disorder (PTSD), and PTSD patients will recover faster with proper social support. The oxytocin system has been proposed to underlie beneficial effects of social support as it is implicated in both social bonding behavior and reducing stress responsivity, notably amygdala reactivity (Koch et al., 2014, Olff et al., 2010, Olff, 2012).

Disturbed sleep is one of the key symptoms of posttraumatic stress disorder (PTSD) and may contribute to the genesis and maintenance of PTSD. Our previously published study*, executed in healthy subjects, suggests that adaptive changes occur in sleep architecture, after emotional experiences, that benefit emotional housekeeping and the attenuation of emotional responses to negative emotional experiences. Little is known, however, about the relation between sleep and emotional memory processing in PTSD.
