Dresden PTSD treatment study: randomized controlled trial of motor vehicle accident survivors

Adolescent optimism - Coping well after severe injury: A qualitative study

BACKGROUND

Trauma is the leading cause of death and disability in children globally. Studies indicate that severe traumatic brain injury (TBI) negatively affects quality of life (QoL) in children, but little is known about QoL after injury in children without TBI. This study aimed to investigate QoL in this group six months post-discharge.

METHODS

Trauma patients aged 13-17 years admitted to a major Scandinavian trauma center were eligible if they met the following criteria: received by a trauma team, ISS > 9, required ICU monitoring, and hospital stay > 4 days. Patients with moderate to severe head injuries (AIS > 2) were excluded. Eighteen consenting adolescents were interviewed six to nine months after discharge.

RESULTS

The main finding was that most participants were "coping well after experienced injuries." A minority reported challenges in daily life, including fatigue and difficulty in keeping up. Few used regular painkillers, and most were unconcerned about long-term consequences. However, many felt that more structured follow-up post-discharge would have been helpful.

CONCLUSION

Among 18 moderate to severely injured adolescents, we found that the majority were coping well. Strong social relationships and involvement in school and social activities was important in all interviews. While several experienced fatigue and challenges in keeping up, the negative impact on daily life was manageable at the time of the interviews.

Evaluation of the Acceptability and Feasibility of Stress Mitigation Education and Support Delivered via Telehealth for People After Road Traffic Musculoskeletal/Orthopedic Injury

PURPOSE

To evaluate the acceptability and feasibility of a consumer co-designed telehealth intervention which aimed to reduce claimant distress by providing pain management strategies, informational and social support to people who had made a compensation claim following road traffic musculoskeletal injury.

METHODS

Eleven claimant participants who were at risk of a poor outcome completed the intervention in a one-on-one setting with the same clinician delivering the program across all sessions.They were interviewed about their experience (acceptability and feasibility including the use of telehealth). Clinicians who delivered the intervention also completed an anonymous feedback survey exploring their experiences delivering the intervention. Interviews were transcribed verbatim and thematic analysis was conducted.

RESULTS

There were four themes which broadly related to the acceptability and feasibility of the intervention as well as the perceived benefits: (1) knowledge is power, (2) healing with social connection, (3) further along than I would have been, and (4) telehealth was acceptable and feasible.

CONCLUSION

The delivery of a co-designed telehealth-delivered stress mitigation intervention to support people with a road traffic musculoskeletal injury was feasible to deliver and acceptable to people who were at risk of a poor outcome. Further research to evaluate the efficacy of the intervention on outcomes such as pain, self-efficacy, and claims costs are needed.

Impact of healthcare interventions on distress following acute musculoskeletal/orthopaedic injury: a scoping review of systematic reviews

BACKGROUND

Musculoskeletal injuries can cause distress, and distress is associated with delayed recovery. Numerous interventions have been developed to facilitate recovery from injury, and several systematic reviews evaluate the efficacy of these interventions for reducing psychological distress.

OBJECTIVES

This scoping review aims to map the synthesised evidence for the relationship between treatment interventions and distress-related outcomes following acute injury. The objectives were (1) to describe the types of interventions that have been evaluated in relation to distress-related outcomes following accidental injury, (2) to examine the scope of distress-related outcomes that have been measured in relation to these interventions and (3) to explore the range of clinical professions that deliver these interventions.

DESIGN

We searched nine electronic databases and grey literature (to 21 April 2022). We included any systematic review reporting on the relationship between interventions delivered in the time following injury and distress-related outcomes. Data relevant to the specific objectives of this scoping review were extracted and described using narrative synthesis.

RESULTS

From 8412 systematic reviews imported for screening, 8266 unique records were screened. 179 were selected for full-text review. 84 systematic reviews were included in the study. Interventional types were pharmacological, psychological, exercise based, physical/manual therapies, virtual reality based, multimodal and workplace based. Interventions were delivered digitally, face to face and using virtual reality by a variety of healthcare professionals, including doctors, nurses, psychologists and physiotherapists. The most frequently reported distress-related variables included anxiety, depression, post-traumatic stress disorder diagnosis.

CONCLUSION

A wide range of interventions may help to mitigate distress following acute accidental musculoskeletal or orthopaedic injury. Even interventions that were not designed to reduce distress were found to improve distress-related outcomes. In view of the important role of distress in recovery from injury, it is recommended that distress-related variables are measured as core outcomes in the evaluation of treatments for acute injuries.

Psychological treatments for post-traumatic stress disorder, anxiety and depression following major physical civilian trauma: A systematic review and meta-analysis

Introduction

Approximately 16% of the world’s burden of disease is attributable to traumatic injury. Psychological symptoms, including post-traumatic stress disorder (PTSD), are prevalent in this population and impact recovery from physical injury. Nevertheless, mental health has not been considered to the same degree as physical health. Psychological interventions are used widely as treatments for PTSD.

Methods

Systematic searches of computerised databases were conducted. Randomised controlled trials of psychological treatments for PTSD following major physical civilian trauma were included. The main outcome measure was clinician-assessed symptoms of PTSD (CAPS), with findings for anxiety and depression also reported. Included studies data were extracted and entered using RevMan 5.3 software. Quality assessments were performed, and data were analysed for summary effects.

Results

10 studies were included. With regard to CAPS <6 months, individual CBT did significantly better than usual care/wait list (SMD (95% CI) = −1.24 [−1.82, −0.67]) and non-CBT treatments (SMD (95% CI) = −1.32 [−2.64, −0.04]). Non-CBT treatments were not significantly better than usual care/wait list (SMD (95% CI) −1.40 [−2.91, 0.11]). CBT was superior to usual care/wait list for reducing depressive (SMD (95% CI) −0.67 [−0.98, −0.37]) and anxiety (SMD (95% CI) −0.70 [−1.22, −0.18]) symptoms both in the shorter and longer term.

Conclusion

Individual CBT was superior to wait list/usual care, and there was limited evidence for non-CBT treatments in reducing clinician and self-rated PTSD, depressive and anxiety symptoms in the shorter term; however, the latter comparison was based on few studies with small sample sizes. Longer-term effects of treatments remain uncertain. There is a need for adequately powered RCTs investigating PTSD treatments following major physical civilian trauma in the longer term. There was considerable heterogeneity in the studies, so care must be taken in interpreting the results of this review.

The power of appraisals in predicting PTSD symptom improvement following cognitive rehabilitation: A randomized clinical trial

BACKGROUND

Patients with PTSD often voice concern over their perceived change in cognitive functioning. However, these negative appraisals do not always align with objective neuropsychological performance, yet are strongly predictive of PTSD symptom severity and self-reported functional impairment.

METHODS

The present study involves a secondary analysis examining the role of appraisals of a subsample of 81 adults with full or subthreshold PTSD on treatment outcomes in a randomized controlled trial investigating the effectiveness of a cognitive rehabilitation treatment, Strategic Memory and Reasoning Training (n = 38), compared to a psychoeducation control arm, the Brain Health Workshop (n = 43). Neither condition addressed PTSD symptoms, focusing instead on cognitive skills training and psychoeducation about the brain.

RESULTS

Intent-to-treat models showed statistically significant improvements for both groups on composite scores of executive functioning and memory. Additionally, both groups experienced clinically significant reductions in PTSD symptoms (assessed via the Clinician-Administered PTSD Interview) and the SMART group showed fewer negative appraisals about cognitive functioning following training. Change in appraisals of cognitive functioning was associated with change in PTSD as well as change in quality of life, with no differential associations based on group status. In contrast, neurocognitive test score changes were not associated with change in symptoms or functional outcomes.

LIMITATIONS

We did not collect data on other appraisals (e.g., self-efficacy), which could have further elucidated pathways of change.

CONCLUSIONS

Our findings suggest that interventions that do not directly target PTSD symptoms can lead to PTSD symptom change via change in appraisals of functioning.

Resiliency and quality of life trajectories after injury

BACKGROUND

Injury can greatly impact patients' long-term quality of life. Resilience refers to an individual's ability to positively adapt after facing stress or trauma. The objective of this study was to examine the relationship between preinjury resiliency scores and quality of life after injury.

METHODS

Two hundred twenty-five adults admitted with an Injury Severity Score greater than 10 but without neurologic injury were included. The 36-item Short Form was administered at the time of admission and repeated at 1 month, 2 months, 4 months, and 12 months after injury. The Connor-Davidson Resilience Scale was completed at admission and scores were categorized into high resiliency or not high resiliency. Group-based trajectory modeling was used to identify distinct recovery trajectories for physical component scores (PCS) and mental component scores (MCS) of the 36-item Short Form. Multinomial logistic regression was used to determine whether baseline resiliency scores were predictive of PCS and MCS recovery trajectories.

RESULTS

Age, race, sex, mechanism of injury, Charlson Comorbidity Index, Injury Severity Score, presence of hypotension on admission, and insurance status were not associated with high resiliency. Compared with those who made less than US $10,000 per year, those who made more than US $50,000 per year had higher odds of being in the high resilience group (odds ratio, 10.92; 95% confidence interval, 2.58-46.32). Three PCS and 5 MCS trajectories were identified. There was no relationship between resilience and PCS trajectory. However, patients with high resiliency scores were 85% less likely to belong to trajectory 1, the trajectory that had the lowest mental health scores over the course of the study. Follow-up for the study was 93.8% for month 1, 82.7% for month 2, 69.4% for month 4, and 63.6% for month 12.

CONCLUSION

Patient resiliency predicts quality of life after injury in regards to mental health with over 25% of patients suffering poor mental health outcome trajectories. Efforts to teach resiliency skills to injured patients could improve long-term mental health for injured patients. Trauma centers are well positioned to carry out such interventions.

Psychological distress following a motor vehicle crash: A systematic review of preventative interventions

INTRODUCTION

Psychological distress following a motor vehicle crash (MVC) is prevalent, especially when the person sustains an associated physical injury. Psychological distress can exhibit as elevated anxiety and depressive mood, as well as presenting as mental disorders such as Post Traumatic Stress Disorder (PTSD) or Major Depressive Disorder (MDD). If unmanaged, psychological distress can contribute to, or exacerbate negative outcomes such as social disengagement (e.g., loss of employment) and poor health-related quality of life, as well as contribute to higher costs to insurers. This systematic review summarises current research concerning early psychological intervention strategies aimed at preventing elevated psychological distress occurring following a MVC.

METHOD

A systematic review of psychological preventative intervention studies was performed. Searches of Medline, Embase, PsychINFO, Web of Science and Cochrane Library were used to locate relevant studies published between 1985 and September 2015. Included studies were those investigating MVC survivors who had received an early psychological intervention aimed at preventing psychological distress, and which had employed pre- and post- measures of constructs such as depression, anxiety and disorders such as PTSD.

RESULTS

Searches resulted in 2608 records. Only six studies investigated a psychological preventative intervention post-MVC. Interventions such as injury health education, physical activity and health promotion, and therapist-assisted problem solving did not result in significant treatment effects. Another six studies investigated psychological interventions given to MVC survivors who were assessed as sub-clinically psychologically distressed prior to their randomisation. Efficacy was varied, however three studies employing cognitive behaviour therapy (CBT) found significant reductions in psychological distress compared to wait-list controls.

CONCLUSION

Psychological interventions aimed at preventing psychological distress post-MVC are limited, often involving small samples, with subsequent poor statistical power and subsequent high risk of bias. These factors make it difficult to draw conclusions, however CBT appears encouraging and therefore worthy of consideration as a preventative intervention.

Prevention of the development of psychological distress following a motor vehicle crash: study protocol for a randomized controlled trial

Background

It is estimated that up to 50 % of motor vehicle crash survivors develop significant psychological distress, such as depressive mood and anxiety, within 6 months of the crash. Associated impacts include loss of employment, delayed return to work, financial and familial stress, and increased medical and compensation costs. The major aim of this research is to investigate the efficacy of interventions for preventing the development of psychological distress following a motor vehicle crash. The efficacy of two brief interventions will be examined: a cognitive behaviour therapy (CBT) programme, targeting mood and anxiety, and a lifestyle programme, targeting sleep, diet and physical activity.

Methods/design

This is a randomized, controlled multisite study. Participants include at least 180 adults injured in a motor vehicle crash who have entered a compensation process. Research will compare outcomes in three groups randomly assigned to: one group of 60 adults, who receive a brief email-delivered CBT programme, with one session every 2 weeks for 10 weeks and telephone contact every 2 weeks; a second group of 60 adults, who receive a brief email-delivered lifestyle intervention involving one session every 2 weeks for 10 weeks with telephone contact; and an active waiting-list control group of 60 adults who are provided claims processing-related reading material along with telephone contact every 2 weeks for 10 weeks. Participants will be recruited within 12 weeks of the motor vehicle crash, and will be comprehensively assessed before and after treatment, and 6 and 12 months post-injury. Assuming an α probability level of 0.05 and a power of 80 %, at least 180 participants will be recruited. The primary outcome measure is the presence and severity of psychological distress or disorder. Secondary outcome measures include assessment of self-efficacy, resilience employment status, social activity and support, lifestyle and physical health factors, along with process outcome measures of treatment acceptability, feasibility and generalizability.

Discussion

This study will determine whether brief email-delivered interventions distributed soon after the injury and entry into the claims process can be effective in preventing the development of psychological distress.

Prolonged exposure, paroxetine and the combination in the treatment of PTSD following a motor vehicle accident. A randomized clinical trial - The "TRAKT" study

BACKGROUND AND OBJECTIVE

Little is known about direct comparisons of the efficacy of trauma-focused psychotherapies and SSRIs. This is the first randomized clinical trial comparing the efficacy of prolonged exposure (PE), paroxetine (Ph) and their combination (Comb) in a sample of adults diagnosed with PTSD following motor vehicle accidents (MVA).

METHODS

A total of 228 people were randomly assigned to a twelve-week treatment of PE (N = 114), Ph (N = 57) or Comb (N = 57).

RESULTS

The ITT analyses showed that the remission rate of PTSD was significantly greater after PE (65.5%) compared with Ph (43.3%), whereas Comb (51.2%) did not differ from either. The differences in dropout rates were not significant between treatments (18.4% - PE; 12.2% - Ph; 22.8% - Comb), while the differences in numbers of refusers were significant (3.5% PE <31.6% Comb <47.4% Ph; p < .01). The changes in self-rated PTSD were significant for each treatment and without significant differences between treatments. Differences between clinician and self-rated outcomes can be explained by depressive symptoms influencing self-rating by the PDS. At a 12 month follow-up treatment results were maintained and different trajectories of functioning were identified.

LIMITATIONS

Larger samples would allow analyses of predictors of treatment response, dropout and refusal.

CONCLUSIONS

In this, largest to date study comparing PE, paroxetine and combination treatment in PTSD PE was more effective than Ph in achieving remission of PTSD. The additive effect of Comb over any monotherapy was not shown.

An update on the efficacy of cognitive-behavioral therapy, cognitive therapy, and exposure therapy for posttraumatic stress disorder

OBJECTIVE

Even though cognitive-behavioral therapy (CBT) is the current treatment of choice for posttraumatic stress disorder (PTSD), it is still unclear which components of its protocol are more important for clinical improvement. This study aims to replicate a previous review, updating findings on the efficacy of CBT, cognitive therapy (CT), and exposure therapy (ET) for PTSD when compared with other well-established treatments or conditions without active treatment.

METHOD

The search was performed in the databases Cochrane, Embase, and Medline. Studies were required to be randomized controlled trials published between 2006 and 2012 comparing CBT, CT, or ET with (1) each other, (2) other active treatments (e.g., EMDR, counseling, supportive therapy), or (3) assessment-only conditions. The main outcome measures were diagnostic and symptomatic remission.

RESULTS

The final sample contained 29 articles. CBT, CT, and ET were shown to be efficacious treatments individually when compared to assessment-only conditions, with no difference found between treatments. Comparison with other active treatments favored ET. Both included studies comparing CBT and EMDR favored the latter.

CONCLUSIONS

CBT and its components still appear to be equally efficacious in improving PTSD symptoms and diagnosis. Even so, a current tendency of researchers to focus on ET exists. EMDR shows interesting results compared to CBT. Further research should clarify the lasting effects, efficiency, and other comparative benefits of each protocol.

Effects of psychotherapy on trauma-related cognitions in posttraumatic stress disorder: a meta-analysis

In the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders criteria for posttraumatic stress disorder (PTSD) incorporate trauma-related cognitions. This adaptation of the criteria has consequences for the treatment of PTSD. Until now, comprehensive information about the effect of psychotherapy on trauma-related cognitions has been lacking. Therefore, the goal of our meta-analysis was to determine which psychotherapy most effectively reduces trauma-related cognitions. Our literature search for randomized controlled trials resulted in 16 studies with data from 994 participants. We found significant effect sizes favoring trauma-focused cognitive-behavioral therapy as compared to nonactive or active nontrauma-focused control conditions of Hedges' g = 1.21, 95% CI [0.69, 1.72], p < .001 and g = 0.36, 95% CI [0.09, 0.63], p = .009, respectively. Treatment conditions with elements of cognitive restructuring and treatment conditions with elements of exposure, but no cognitive restructuring reduced trauma-related cognitions almost to the same degree. Treatments with cognitive restructuring had small advantages over treatments without cognitive restructuring. We concluded that trauma-focused cognitive-behavioral therapy effectively reduces trauma-related cognitions. Treatments comprising either combinations of cognitive restructuring and imaginal exposure and in vivo exposure, or imaginal exposure and in vivo exposure alone showed the largest effects.

Psychological therapies for chronic post-traumatic stress disorder (PTSD) in adults

BACKGROUND

Post-traumatic stress disorder (PTSD) is a distressing condition, which is often treated with psychological therapies. Earlier versions of this review, and other meta-analyses, have found these to be effective, with trauma-focused treatments being more effective than non-trauma-focused treatments. This is an update of a Cochrane review first published in 2005 and updated in 2007.

OBJECTIVES

To assess the effects of psychological therapies for the treatment of adults with chronic post-traumatic stress disorder (PTSD).

SEARCH METHODS

For this update, we searched the Cochrane Depression, Anxiety and Neurosis Group's Specialised Register (CCDANCTR-Studies and CCDANCTR-References) all years to 12th April 2013. This register contains relevant randomised controlled trials from: The Cochrane Library (all years), MEDLINE (1950 to date), EMBASE (1974 to date), and PsycINFO (1967 to date). In addition, we handsearched the Journal of Traumatic Stress, contacted experts in the field, searched bibliographies of included studies, and performed citation searches of identified articles.

SELECTION CRITERIA

Randomised controlled trials of individual trauma-focused cognitive behavioural therapy (TFCBT), eye movement desensitisation and reprocessing (EMDR), non-trauma-focused CBT (non-TFCBT), other therapies (supportive therapy, non-directive counselling, psychodynamic therapy and present-centred therapy), group TFCBT, or group non-TFCBT, compared to one another or to a waitlist or usual care group for the treatment of chronic PTSD. The primary outcome measure was the severity of clinician-rated traumatic-stress symptoms.

DATA COLLECTION AND ANALYSIS

We extracted data and entered them into Review Manager 5 software. We contacted authors to obtain missing data. Two review authors independently performed 'Risk of bias' assessments. We pooled the data where appropriate, and analysed for summary effects.

MAIN RESULTS

We include 70 studies involving a total of 4761 participants in the review. The first primary outcome for this review was reduction in the severity of PTSD symptoms, using a standardised measure rated by a clinician. For this outcome, individual TFCBT and EMDR were more effective than waitlist/usual care (standardised mean difference (SMD) -1.62; 95% CI -2.03 to -1.21; 28 studies; n = 1256 and SMD -1.17; 95% CI -2.04 to -0.30; 6 studies; n = 183 respectively). There was no statistically significant difference between individual TFCBT, EMDR and Stress Management (SM) immediately post-treatment although there was some evidence that individual TFCBT and EMDR were superior to non-TFCBT at follow-up, and that individual TFCBT, EMDR and non-TFCBT were more effective than other therapies. Non-TFCBT was more effective than waitlist/usual care and other therapies. Other therapies were superior to waitlist/usual care control as was group TFCBT. There was some evidence of greater drop-out (the second primary outcome for this review) in active treatment groups. Many of the studies were rated as being at 'high' or 'unclear' risk of bias in multiple domains, and there was considerable unexplained heterogeneity; in addition, we assessed the quality of the evidence for each comparison as very low. As such, the findings of this review should be interpreted with caution.

AUTHORS' CONCLUSIONS

The evidence for each of the comparisons made in this review was assessed as very low quality. This evidence showed that individual TFCBT and EMDR did better than waitlist/usual care in reducing clinician-assessed PTSD symptoms. There was evidence that individual TFCBT, EMDR and non-TFCBT are equally effective immediately post-treatment in the treatment of PTSD. There was some evidence that TFCBT and EMDR are superior to non-TFCBT between one to four months following treatment, and also that individual TFCBT, EMDR and non-TFCBT are more effective than other therapies. There was evidence of greater drop-out in active treatment groups. Although a substantial number of studies were included in the review, the conclusions are compromised by methodological issues evident in some. Sample sizes were small, and it is apparent that many of the studies were underpowered. There were limited follow-up data, which compromises conclusions regarding the long-term effects of psychological treatment.

A randomized controlled trial of cognitive-behavioral therapy for the treatment of PTSD in the context of chronic whiplash

OBJECTIVES

Whiplash-associated disorders (WAD) are common and involve both physical and psychological impairments. Research has shown that persistent posttraumatic stress symptoms are associated with poorer functional recovery and physical therapy outcomes. Trauma-focused cognitive-behavioral therapy (TF-CBT) has shown moderate effectiveness in chronic pain samples. However, to date, there have been no clinical trials within WAD. Thus, this study will report on the effectiveness of TF-CBT in individuals meeting the criteria for current chronic WAD and posttraumatic stress disorder (PTSD).

METHOD

Twenty-six participants were randomly assigned to either TF-CBT or a waitlist control, and treatment effects were evaluated at posttreatment and 6-month follow-up using a structured clinical interview, self-report questionnaires, and measures of physiological arousal and sensory pain thresholds.

RESULTS

Clinically significant reductions in PTSD symptoms were found in the TF-CBT group compared with the waitlist at postassessment, with further gains noted at the follow-up. The treatment of PTSD was also associated with clinically significant improvements in neck disability, physical, emotional, and social functioning and physiological reactivity to trauma cues, whereas limited changes were found in sensory pain thresholds.

DISCUSSION

This study provides support for the effectiveness of TF-CBT to target PTSD symptoms within chronic WAD. The finding that treatment of PTSD resulted in improvements in neck disability and quality of life and changes in cold pain thresholds highlights the complex and interrelating mechanisms that underlie both WAD and PTSD. Clinical implications of the findings and future research directions are discussed.

Post-traumatic growth as outcome of a cognitive-behavioural therapy trial for motor vehicle accident survivors with PTSD

OBJECTIVES

Treatment effects on post-traumatic growth (PTG) and its subdomains were investigated together with predictors of the Janus-face model of PTG.

DESIGN

Effects were investigated within a randomized controlled trial of cognitive-behavioural therapy (CBT) for post-traumatic stress disorder (PTSD).

METHOD

Forty motor vehicle accident survivors were randomly assigned to a treatment or waiting condition. PTG was measured by the Post-traumatic Growth Inventory and complemented by its possible predictors (optimism, openness).

RESULTS

The CBT treatment proved to be highly effective in terms of PTSD symptom reduction. In contrast to previous findings, however, there was no treatment effect on PTG in general. The CBT group showed, however, increases in PTG subdomains 'new possibilities' and 'personal strength'.

CONCLUSIONS

The results of this study caution researchers to naively expect PTG as a uniformly positive outcome to evaluate treatment effectiveness.

Cognitive behavioral therapy for the treatment of post-traumatic stress disorder: a review

BACKGROUND

Post-traumatic stress disorder (PTSD) is a psychiatric sequel to a stressful event or situation of an exceptionally threatening or catastrophic nature. Cognitive behavioral therapy (CBT) has been used in the management of PTSD for many years. This paper reviews the effectiveness of CBT for the treatment of PTSD following various types of trauma, its potential to prevent PTSD, methods used in CBT, and reflects on the mechanisms of action of CBT in PTSD.

METHODS

Electronic databases, including PubMed, were searched for articles on CBT and PTSD. Manual searches were conducted for cross-references in the relevant journal sites.

RESULTS

The current literature reveals robust evidence that CBT is a safe and effective intervention for both acute and chronic PTSD following a range of traumatic experiences in adults, children, and adolescents. However, nonresponse to CBT by PTSD can be as high as 50%, contributed to by various factors, including comorbidity and the nature of the study population. CBT has been validated and used across many cultures, and has been used successfully by community therapists following brief training in individual and group settings. There has been effective use of Internet-based CBT in PTSD. CBT has been found to have a preventive role in some studies, but evidence for definitive recommendations is inadequate. The effect of CBT has been mediated mostly by the change in maladaptive cognitive distortions associated with PTSD. Many studies also report physiological, functional neuroimaging, and electroencephalographic changes correlating with response to CBT.

CONCLUSION

There is scope for further research on implementation of CBT following major disasters, its preventive potential following various traumas, and the neuropsychological mechanisms of action.

Post-traumatic stress disorder

INTRODUCTION

Post-traumatic stress disorder (PTSD) may affect 10% of women and 5% of men at some stage, and symptoms may persist for several years. Risk factors include major trauma, lack of social support, peritraumatic dissociation, and previous psychiatric history or personality factors.

METHODS AND OUTCOMES

We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of interventions to prevent PTSD? What are the effects of interventions to treat PTSD? We searched: Medline, Embase, The Cochrane Library, and other important databases up to March 2009 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).

RESULTS

We found 46 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.

CONCLUSIONS

In this systematic review we present information relating to the effectiveness and safety of the following interventions: affect management; antiepileptic drugs; antihypertensive drugs; benzodiazepines; brofaromine; CBT; drama therapy; eye movement desensitisation and reprocessing; fluoxetine; group therapy; hydrocortisone; hypnotherapy; inpatient treatment programmes; Internet-based psychotherapy; mirtazapine; multiple-session CBT; multiple-session collaborative trauma support; multiple-session education; nefazodone; olanzapine; paroxetine; phenelzine; psychodynamic psychotherapy; risperidone; SSRIs (versus other antidepressants); sertraline; single-session group debriefing; single-session individual debriefing; supportive psychotherapy; supportive counselling; temazepam; tricyclic antidepressants; and venlafaxine.

Negative self-appraisals in treatment-seeking survivors of motor vehicle accidents

Recent cognitive models stress the impact that negative appraisals have on the maintenance of posttraumatic stress disorder (PTSD). The aim of this study was to investigate the role of posttraumatic negative cognitions in 110 survivors of motor vehicle accidents (MVAs) and to examine the effect of cognitive-behavioral treatment on negative appraisals in a sample of 42 patients with full or sub-syndromal PTSD. We investigated whether posttraumatic negative cognitions predicted PTSD diagnosis and symptom severity, and whether treatment-related changes in negative appraisals were associated with PTSD symptom reduction. Negative posttraumatic cognitions were significantly associated with PTSD diagnosis and severity, and explained 54% of the variance of the PTSD severity. Furthermore, treatment-related reductions in negative appraisals about the self were highly associated with PTSD-symptom-reduction. Our results raise question about whether there are factors that make the self more vulnerable in some people but not in others.

Group cognitive behavior therapy for chronic posttraumatic stress disorder: an initial randomized pilot study

Individuals with posttraumatic stress disorder (PTSD) related to a serious motor vehicle accident were randomly assigned to either group cognitive behavioral treatment(GCBT) or a minimum contact comparison group (MCC).Compared to the MCC participants (n=16), individuals who completed GCBT (n=17) showed significant reductions in PTSD symptoms, whether assessed using clinical interview or a self-report measure. Among treatment completers, 88.3% of GCBT participants did not satisfy criteria for PTSD at posttreatment assessment, relative to31.3% of the MCC participants. Examination of anxiety,depression, and pain measures did not show a unique advantage of GCBT. Treatment-related gains were maintained over a 3-month follow-up interval. Patients reported satisfaction with GCBT, and attrition from this treatment was comparable with individually administered CBTs.Results are discussed in light of modifications necessitated by the group treatment format, with suggestions for future study of this group intervention.

Changes in brain electrical activity after cognitive behavioral therapy for posttraumatic stress disorder in patients injured in motor vehicle accidents

OBJECTIVE

To explore changes for the first time in neural processing due to effective cognitive behavioral therapy (CBT) in posttraumatic stress disorder (PTSD) after severe motor vehicle accidents. Recent studies have highlighted the role of right hemisphere activation during withdrawal-related emotions (e.g., anxiety). There has been little research on changes in brain function due to cognitive-behavioral interventions in anxiety disorders.

METHODS

We conducted a randomized, controlled trial comparing cognitive-behavioral therapy with an assessment-only Wait-list condition. Spontaneous electroencephalographic activity was recorded from left and right anterior and posterior regions in participants with PTSD/subsyndromal PTSD receiving CBT (n = 17) before and after a CBT program. Wait-list controls (n = 18) were investigated before and after 3 months.

RESULTS

At the pretreatment assessment, a pattern of increased right-sided activation during exposure to a trauma-related picture (relative to a neutral picture) was observed in both CBT and Wait-list participants. At posttreatment, there was a greater reduction of right anterior activation in the CBT group as compared with Wait-list controls. Across both groups, PTSD symptom reduction was significantly positively correlated with a decrease in right anterior activation to the trauma stimulus.

CONCLUSIONS

These findings suggest that effective CBT treatment of PTSD may be accompanied by adaptive changes in asymmetrical brain function. Future studies are needed to confirm our findings.

Assessment and treatment of PTSD after a motor vehicle collision: Empirical findings and clinical observations

Individuals who experience a serious motor vehicle accident (MVA) are at increased risk for psychological problems, particularly Posttraumatic Stress Disorder (PTSD). In this article, we review the literature on PTSD among MVA survivors, with particular attention to available instruments to screen for and assess symptomatology of the disorder. Approaches to the treatment of PTSD in this population are reviewed, separated into interventions designed to prevent PTSD in unselected samples, treatment targeting individuals with Acute Stress Disorder that are designed to prevent subsequent development of PTSD, and therapy for individuals with chronic PTSD. Treatment process issues are discussed, in an effort to integrate empirical findings with clinical observations. The empirical literature suggests several approaches to treatment that have good potential outcomes, although continued work is needed to identify factors that predict treatment response, as well as augment individual-based treatment formats.

Internet-based treatment for PTSD reduces distress and facilitates the development of a strong therapeutic alliance: a randomized controlled clinical trial

BACKGROUND

The present study was designed to evaluate the efficacy of an internet-based therapy (Interapy) for Posttraumatic Stress Disorder (PTSD) in a German speaking population. Also, the quality of the online therapeutic relationship, its development and its relevance as potential moderator of the treatment effects was investigated.

METHOD

Ninety-six patients with posttraumatic stress reactions were allocated at random to ten sessions of Internet-based cognitive behavioural therapy (CBT) conducted over a 5-week period or a waiting list control group. Severity of PTSD was the primary outcome. Secondary outcome variables were depression, anxiety, dissociation and physical health. Follow-up assessments were conducted at the end of treatment and 3 months after treatment.

RESULTS

From baseline to post-treatment assessment, PTSD severity and other psychopathological symptoms were significantly improved for the treatment group (intent-to-treat group x time interaction effect size d = 1.40). Additionally, patients of the treatment condition showed significantly greater reduction of co-morbid depression and anxiety as compared to the waiting list condition. These effects were sustained during the 3-months follow-up period. High ratings of the therapeutic alliance and low drop-out rates indicated that a positive and stable therapeutic relationship could be established online. Significant improvement of the online working alliance in the course of treatment and a substantial correlation between the quality of the online relationship at the end of treatment and treatment outcome emerged.

CONCLUSION

Interapy proved to be a viable treatment alternative for PTSD with large effect sizes and sustained treatment effects. A stable and positive online therapeutic relationship can be established through the Internet which improved during the treatment process.

Quality of life after multiple trauma: the effect of early onset psychotherapy on quality of life in trauma patients

BACKGROUND AND AIMS

The aim of this study was to improve health-related quality of life (HRQOL) related to depression, anxiety, pain, physical functioning and social aspects for severely injured trauma survivors by early onset cognitive behavioural therapy applied on the surgical ward.

MATERIALS AND METHODS

The study was a randomised, controlled study. Of 298 primary screened patients 171 were eligible and randomised. Ninety-two patients adhered to follow-up investigations at 6 and 12 months. Main outcome measure was a sum score according to O'Brien calculated of five different questionnaires (BDI, SF-36, STAI, SCL 90R, F-SOZU-22).

RESULTS

The sum score for overall HRQOL did not show significant group differences at follow-up. Effects on HRQOL sub-dimensions within groups have been found. In the dimension of depression therapy group showed significant improvement from the first measurement to discharge from hospital (p < 0.001), 6 MFU (p = 0.004) and to 12 MFU (p = 0.013). Measures of anxiety showed significant improvement for the therapy group at discharge from hospital (p = 0.001). In the control group there was only a significant reduction in depression and anxiety from surgical ward to discharge (p = 0.013/p = 0.031).

CONCLUSIONS

Early onset cognitive therapy is not effective in improving overall HRQOL of severely injured patients but shows promising effects on depression and anxiety up to 12 months after trauma.

Cardiovascular correlates of motor vehicle accident related posttraumatic stress disorder and its successful treatment

Persons with posttraumatic stress disorder (PTSD) have been shown to display elevated baseline cardiovascular activity and a heightened physiological reactivity to trauma-related stimuli. Study 1 examined differences in baseline heart rate (HR) and HR reactivity in 68 survivors of motor vehicle accidents (MVAs) and healthy controls without MVA. MVA survivors with PTSD (n=26), subsyndromal PTSD (n=22), traumatized controls without PTSD (non-PTSD with MVA, n=20) and healthy controls without MVA (HC, n=27) underwent measurement of HR during baseline and exposure to a neutral, positive, negative, and trauma-related picture. PTSD patients showed elevated baseline HR and increased HR reactivity only during exposure to the trauma-related picture. Study 2 investigated whether the elevated physiological responses observed in Study 1 normalized after cognitive behavioral therapy (CBT). We conducted a randomized, controlled treatment trial comparing CBT (n=17) to a Wait-list condition (WLC, n=18). Results showed a greater decrease in HR reactivity for CBT than for WLC. The change in HR reactivity was associated with clinical improvement.
