A systematic review of factors associated with outcome of psychological treatments for post-traumatic stress disorder

Objective: Psychological interventions for post-traumatic stress disorder (PTSD) are not always effective and can leave some individuals with enduring symptoms. Little is known about factors that are associated with better or worse treatment outcome. Our objective was to address this gap. Method: We undertook a systematic review following Cochrane Collaboration Guidelines. We included 126 randomized controlled trials (RCTs) of psychological interventions for PTSD and examined factors that were associated with treatment outcome, in terms of severity of PTSD symptoms post-treatment, and recovery or remission. Results: Associations were neither consistent nor strong. Two factors were associated with smaller reductions in severity of PTSD symptoms post-treatment: comorbid diagnosis of depression, and higher PTSD symptom severity at baseline assessment. Higher education, adherence to homework and experience of a more recent trauma were associated with better treatment outcome. Conclusion: Identifying and understanding why certain factors are associated with treatment outcome is vital to determine which individuals are most likely to benefit from particular treatments and to develop more effective treatments in the future. There is an urgent need for consistent and standardized reporting of factors associated with treatment outcome in all clinical trials

Managing the risk of post-traumatic stress disorder (PTSD): best practice for prevention, detection and treatment

In this issue, Bonde and colleagues1 present a comprehensive systematic review of the time course of symptoms in post-traumatic stress disorder (PTSD) with delayed expression. Finding that in most cases PTSD is preceded by traumatic stress symptoms during the first year, they conclude a need to monitor traumatic stress symptoms after trauma exposure to identify those at risk of developing PTSD. This work draws attention to the prevalence of traumatic stress symptoms after trauma exposure, as well as indicating the potential to identify those likely to develop PTSD at a later point in time based on earlier symptoms. This indicates the value of revisiting what we know about best practice in managing the risk of PTSD

Sleep disturbance in post-traumatic stress disorder (PTSD): a systematic review and meta-analysis of actigraphy studies

Background Sleep disturbance has been described as a ‘hallmark’ symptom of posttraumatic stress disorder (PTSD). Although there are robust findings of self-reported sleep disturbance in PTSD, evidence of sleep disturbance measured using actigraphy is less certain. Objective To conduct a systematic review and meta-analysis to determine whether there are any significant differences between individuals with and without PTSD in actigraph-derived sleep measures. Method Case-control studies comparing participants with current PTSD to those without PTSD were eligible for inclusion. Sleep parameters of interest were: (1) total sleep time; (2) sleep onset latency; (3) wake after sleep onset (WASO); and (4) sleep efficiency. Data were meta-analysed as standardised mean differences (SMDs) and potential sources of heterogeneity were explored through meta-regression. Six actigraphy studies with 405 participants were included. Results There was no evidence of a statistically significant difference between those with and without PTSD in total sleep time (SMD 0.09, 95%CI −0.23 to 0.42); WASO (SMD 0.18, 95%CI −0.06 to 0.43); sleep latency (SMD 0.32, 95%CI −0.04 to 0.69); or sleep efficiency (SMD −0.28, 95%CI −0.78 to 0.21). Conclusions Further high-quality research is required to determine whether there is a true difference in sleep between those with and without PTSD

Active duty and ex-serving military personnel with post-traumatic stress disorder treated with psychological therapies: systematic review and meta-analysis

Background: Post-traumatic stress disorder (PTSD) is a major cause of morbidity amongst active duty and ex-serving military personnel. In recent years increasing efforts have been made to develop more effective treatments. Objective: To determine which psychological therapies are efficacious in treating active duty and ex-serving military personnel with post-traumatic stress disorder (PTSD). Method: A systematic review was undertaken according to Cochrane Collaboration Guidelines. The primary outcome measure was reduction in PTSD symptoms and the secondary outcome dropout. Results: Twenty-four studies with 2386 participants were included. Evidence demonstrated that CBT with a trauma focus (CBT-TF) was associated with the largest evidence of effect when compared to waitlist/usual care in reducing PTSD symptoms post treatment (10 studies; n = 524; SMD −1.22, −1.78 to −0.66). Group CBT-TF was less effective when compared to individual CBT-TF at reducing PTSD symptoms post treatment (1 study; n = 268; SMD −0.35, −0.11 to −0.59). Eye Movement Desensitization and Reprocessing (EMDR) therapy was not effective when compared to waitlist/usual care at reducing PTSD symptoms post treatment (4 studies; n = 92; SMD −0.83, −1.75 to 0.10). There was evidence of greater dropout from CBT-TF therapies compared to waitlist and Present Centred Therapy. Conclusions: The evidence, albeit limited, supports individual CBT-TF as the first-line psychological treatment of PTSD in active duty and ex-serving personnel. There is evidence for Group CBT-TF, but this is not as strong as for individual CBT-TF. EMDR cannot be recommended as a first line therapy at present and urgently requires further evaluation. Lower effect sizes than for other populations with PTSD and high levels of drop-out suggest that CBT-TF in its current formats is not optimally acceptable and further research is required to develop and evaluate more effective treatments for PTSD and complex PTSD in active duty and ex-serving military personnel

The role of the nobility in the creation of Gallo-Frankish society in the late fifth and sixth centuries AD

The aim of this dissertation is to explore the contribution made by the nobility, both Gallo-Roman and Frankish, to the creation of a new society after the collapse of imperial authority in the west, Gallo-Frankish society. The first chapter of this dissertation is a review of the sources, both ancient and modern, used in the research undertaken for this dissertation. It is important to realise that, while not as numerous as those of other periods, sufficient ancient material survives to make a study such as this valid. Modern issues and debates will be highlighted, including an indication of what led me to this particular thesis. The second chapter outlines the history of Gaul and the barbarians to the middle of the fifth century. It then looks at the institutions that were the backbone of Gallo-Roman society. The third chapter explores the lives of a number of individuals who lived in Gaul during the late third and fourth centuries. They exemplify the challenges that faced the nobility and the ways they found of facing them. Chapter four introduces the Franks as the successors to imperial rule in Gaul. A narrative history is followed by a study of the institutions that they made use of in establishing their power. Chapter five narrows the focus still further and looks at the role that the monarchy and the nobility had to play in the creation of Gallo-Frankish society. It will look at specific examples in order to demonstrate the vital role that the fusion taking place between Gallo-Romans and Franks played in this process. The final chapter, chapter six reaches the conclusion that Gallo-Frankish society was based on an amalgamation of Gallo-Romans and Franks, an amalgamation that was remarkably peaceful, given the events of the period

Non-pharmacological and non-psychological approaches to the treatment of PTSD: results of a systematic review and meta-analyses

ABSTRACT Background: Non-pharmacological and non-psychological approaches to the treatment of post-traumatic stress disorder (PTSD) have often been excluded from systematic reviews and meta-analyses. Consequently, we know little regarding their efficacy. Objective: To determine the effect sizes of non-pharmacological and non-psychological treatment approaches for PTSD. Method: We undertook a systematic review and meta-analyses following Cochrane Collaboration guidelines. A pre-determined definition of clinical importance was applied to the results and the quality of evidence was appraised using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. Results: 30 randomised controlled trials (RCTs) of a range of heterogeneous non- psychological and non-pharmacological interventions (28 in adults, two in children and adolescents) were included. There was emerging evidence for six different approaches (acupuncture, neurofeedback, saikokeishikankyoto (a herbal preparation), somatic experiencing, transcranial magnetic stimulation, and yoga). Conclusions: Given the level of evidence available, it would be premature to offer non- pharmacological and non-psychological interventions routinely, but those with evidence of efficacy provide alternatives for people who do not respond to, do not tolerate or do not want more conventional evidence-based interventions. This review should stimulate further research in this area

Internet-based cognitive and behavioural therapies for posttraumatic stress disorder (PTSD) in adults

Therapist-delivered trauma-focused psychological therapies are an effective treatment for post-traumatic stress disorder (PTSD). These have become the accepted first-line treatments for the disorder. Despite the established evidence-base for these therapies, they are not always widely available or accessible.Many barriers limit treatment uptake, such as the limited number of qualified therapists to deliver the interventions, cost, and compliance issues, such as time off work, childcare, and transportation, associated with the need to attend weekly appointments. Delivering cognitive behavioural therapy (CBT) on the Internet is an effective and acceptable alternative to therapist-delivered treatments for anxiety and depression. However, fewer Internet-based therapies have been developed and evaluated for PTSD, and uncertainty surrounds the efficacy of Internet-based cognitive and behavioural therapy (I-C/BT) for PTSD. Objectives To assess the effects of I-C/BT for PTSD in adults. Search methods We searched the Cochrane Common Mental Disorders Group's Specialised Register (CCMDCTR) to June 2016 and identified four studies meeting the inclusion criteria. The CCMDCTR includes relevant randomised controlled trials (RCT) from MEDLINE, Embase, and PsycINFO.We also searched online clinical trial registries and reference lists of included studies, and contacted researchers in the field to identify additional and ongoing studies. We ran an update search on 1 March 2018, and identified four additional completed studies, which we added to the analyses along with two that were previously awaiting classification. Selection criteria We searched for RCTs of I-C/BT compared to face-to-face or Internet-based psychological treatment, psychoeducation, wait list or care as usual. We included studies of adults (aged over 16 years or over), in which at least 70% of the participants met the diagnostic criteria for PTSD, according to the Diagnostic and Statistical Manual (DSM) or the International Classification of Diseases (ICD)
