Objective: The authors present a multidimensional meta-analysis of studies published between 1980 and 2003 on psychotherapy for PTSD. Method: Data on variables not previously meta-analyzed such as inclusion and exclusion criteria and rates, recovery and improvement rates, and follow-up data were examined. Results: Results suggest that psychotherapy for PTSD leads to a large initial improvement from baseline. More than half of patients who complete treatment with various forms of cognitive behavior therapy or eye movement desensitization and reprocessing improve. Reporting of metrics other than effect size provides a somewhat more nuanced account of outcome and generalizability. Conclusions: The majority of patients treated with psychotherapy for PTSD in randomized trials recover or improve, rendering these approaches some of the most effective psychosocial treatments devised to date. Several caveats, however, are important in applying these findings to patients treated in the community. Exclusion criteria and failure to address polysymptomatic presentations render generalizability to the population of PTSD patients indeterminate. The majority of patients posttreatment continue to have substantial residual symptoms, and follow-up data beyond very brief intervals have been largely absent. Future research intended to generalize to patients in practice should avoid exclusion criteria other than those a sensible clinician would impose in practice (e.g., schizophrenia), should avoid wait-list and other relatively inert control conditions, and should follow patients through at least 2 years.

A Multidimensional Meta-Analysis of Psychotherapy for PTSD.

Background The relative efficacy of different psychological treatments for chronic post-traumatic stress disorder (PTSD) is unclear. 

Aims To determine the efficacy of specific psychological treatments for chronic PTSD. 

Method In a systematic review of randomised controlled trials, eligible studies were assessed against methodological quality criteria and data were extracted and analysed. 

Results Thirty-eight randomised controlled trials were included in the meta-analysis. Trauma-focused cognitive–behavioural therapy (TFCBT), eye movement desensitisation and reprocessing (EMDR), stress management and group cognitive–behavioural therapy improved PTSD symptoms more than waiting-list or usual care. There was inconclusive evidence regarding other therapies. There was no evidence of a difference in efficacy between TFCBT and EMDR but there was some evidence that TFCBT and EMDR were superior to stress management and other therapies, and that stress management was superior to other therapies. 

Conclusions The first-line psychological treatment for PTSD should be trauma-focused (TFCBT or EMDR).

Psychological treatments for chronic post-traumatic stress disorder : Systematic review and meta-analysis

ContextThe prevalence of posttraumatic stress disorder (PTSD) is elevated among women who have served in the military, but no prior study has evaluated treatment for PTSD in this population. Prior research suggests that cognitive behavioral therapy is a particularly effective treatment for PTSD.ObjectiveTo compare prolonged exposure, a type of cognitive behavioral therapy, with present-centered therapy, a supportive intervention, for the treatment of PTSD.Design, Setting, and ParticipantsA randomized controlled trial of female veterans (n=277) and active-duty personnel (n=7) with PTSD recruited from 9 VA medical centers, 2 VA readjustment counseling centers, and 1 military hospital from August 2002 through October 2005.InterventionParticipants were randomly assigned to receive prolonged exposure (n = 141) or present-centered therapy (n = 143), delivered according to standard protocols in 10 weekly 90-minute sessions.Main Outcome MeasuresPosttraumatic stress disorder symptom severity was the primary outcome. Comorbid symptoms, functioning, and quality of life were secondary outcomes. Blinded assessors collected data before and after treatment and at 3- and 6-month follow-up.ResultsWomen who received prolonged exposure experienced greater reduction of PTSD symptoms relative to women who received present-centered therapy (effect size, 0.27; P = .03). The prolonged exposure group was more likely than the present-centered therapy group to no longer meet PTSD diagnostic criteria (41.0% vs 27.8%; odds ratio, 1.80; 95% confidence interval, 1.10-2.96; P = .01) and achieve total remission (15.2% vs 6.9%; odds ratio, 2.43; 95% confidence interval, 1.10-5.37; P = .01). Effects were consistent over time in longitudinal analyses, although in cross-sectional analyses most differences occurred immediately after treatment.ConclusionsProlonged exposure is an effective treatment for PTSD in female veterans and active-duty military personnel. It is feasible to implement prolonged exposure across a range of clinical settings.Trial Registrationclinicaltrials.gov Identifier: NCT00032617

Cognitive Behavioral Therapy for Posttraumatic Stress Disorder in Women: A Randomized Controlled Trial

OBJECTIVE: The term “mood stabilizer” is widely used in the context of treating bipolar disorder, but the U.S. Food and Drug Administration (FDA) does not officially recognize the term, and no consensus definition is accepted among investigators. The authors propose a “two-by-two” definition by which an agent is considered a mood stabilizer if it has efficacy in treating acute manic and depressive symptoms and in prophylaxis of manic and depressive symptoms in bipolar disorder. They review the literature on the efficacy of agents in any of these four roles to determine which if any agents meet this definition of mood stabilizer. METHOD: The authors conducted a comprehensive review of English-language literature describing peer-reviewed, U.S. Agency for Healthcare Research and Quality class A controlled trials in order to identify agents with efficacy in any of the four roles included in their definition of a mood stabilizer. The trials were classified as positive or negative on the basis of primary outcom...

What Is a “Mood Stabilizer”? An Evidence-Based Response

Importance Posttraumatic stress disorder (PTSD) is a disabling psychiatric disorder common among military personnel and veterans. First-line psychotherapies most often recommended for PTSD consist mainly of “trauma-focused” psychotherapies that involve focusing on details of the trauma or associated cognitive and emotional effects. Objective To examine the effectiveness of psychotherapies for PTSD in military and veteran populations. Evidence Review PubMed, PsycINFO, and PILOTS were searched for randomized clinical trials (RCTs) of individual and group psychotherapies for PTSD in military personnel and veterans, published from January 1980 to March 1, 2015. We also searched reference lists of articles, selected reviews, and meta-analyses. Of 891 publications initially identified, 36 were included. Findings Two trauma-focused therapies, cognitive processing therapy (CPT) and prolonged exposure, have been the most frequently studied psychotherapies for military-related PTSD. Five RCTs of CPT (that included 481 patients) and 4 RCTs of prolonged exposure (that included 402 patients) met inclusion criteria. Focusing on intent-to-treat outcomes, within-group posttreatment effect sizes for CPT and prolonged exposure were large (Cohen d range, 0.78-1.10). CPT and prolonged exposure also outperformed waitlist and treatment-as-usual control conditions. Forty-nine percent to 70% of participants receiving CPT and prolonged exposure attained clinically meaningful symptom improvement (defined as a 10- to 12-point decrease in interviewer-assessed or self-reported symptoms). However, mean posttreatment scores for CPT and prolonged exposure remained at or above clinical criteria for PTSD, and approximately two-thirds of patients receiving CPT or prolonged exposure retained their PTSD diagnosis after treatment (range, 60%-72%). CPT and prolonged exposure were marginally superior compared with non–trauma-focused psychotherapy comparison conditions. Conclusions and Relevance In military and veteran populations, trials of the first-line trauma-focused interventions CPT and prolonged exposure have shown clinically meaningful improvements for many patients with PTSD. However, nonresponse rates have been high, many patients continue to have symptoms, and trauma-focused interventions show marginally superior results compared with active control conditions. There is a need for improvement in existing PTSD treatments and for development and testing of novel evidence-based treatments, both trauma-focused and non–trauma-focused.

Psychotherapy for Military-Related PTSD: A Review of Randomized Clinical Trials.

Background Department of Veterans Affairs Cooperative Study 420 is a randomized clinical trial of 2 methods of group psychotherapy for treating posttraumatic stress disorder (PTSD) in male Vietnam veterans. Methods Vietnam veterans (360 men) were randomly assigned to receive trauma-focused group psychotherapy or a present-centered comparison treatment that avoided trauma focus. Treatment was provided weekly to groups of 6 members for 30 weeks, followed by 5 monthly booster sessions. Severity of PTSD was the primary outcome. Additional measures were other psychiatric symptoms, functional status, quality of life, physical health, and service utilization. Follow-up assessments were conducted at the end of treatment (7 months) and at the end of the booster sessions (12 months); 325 individuals participated in 1 or both assessments. Additional follow-up for PTSD severity was performed in a subset of participants at 18 and 24 months. Results Although posttreatment assessments of PTSD severity and other measures were significantly improved from baseline, intention-to-treat analyses found no overall differences between therapy groups on any outcome. Analyses of data from participants who received an adequate dose of treatment suggested that trauma-focused group therapy reduced avoidance and numbing and, possibly, PTSD symptoms. Dropout from treatment was higher in trauma-focused group treatment. Average improvement was modest in both treatments, although approximately 40% of participants showed clinically significant change. Conclusions This study did not find a treatment effect for trauma-focused group therapy. The difference between the effectiveness and adequate dose findings suggests the possible value of methods to enhance the delivery of cognitive-behavioral treatments in clinical practice settings.

Randomized Trial of Trauma-Focused Group Therapy for Posttraumatic Stress Disorder

Moderators of PTSD symptom change in group cognitive behavioral therapy and group present centered therapy.

In the wake of terrorism, survivors must balance two competing tasks: to make sense of the trauma, and to reestablish a secure foundation in the face of intrusions that overwhelm the current time frame. Present-centered group therapy (PCGT) emphasizes attention to emotional responses, needs, situations, and wants, supporting recalibration of trauma-based symptoms, attitudes, and behaviors. A review of literature examining five studies on the efficacy of present-centered or supportive group therapy models for trauma treatment indicates improvements in symptoms such as depression, anxiety, and self-esteem. If a trauma trigger occurs in the group or the treatment setting, the group may become preoccupied with reexperiencing. Occasional inadvertent shifts into discussion of the trauma can be processed in a present-centered fashion, focusing on affective responses to the disclosure. PCGT validates the impact of trauma in the lives of survivors, it focuses away from the details of the terrorism experience in order to diffuse extreme affects related to hyperarousal.
