The relative efficacy of bona fide psychotherapies for treating post-traumatic stress disorder: a meta-analysis of direct comparisons

A formative evaluation of 'Mind Matters: Overcoming Adversity and Building Resiliency' with Hispanic adolescents prior to and during Covid-19

Youth living in poverty are more likely to experience cumulative stressors including multiple adverse childhood events. Further, the Covid-19 pandemic has disproportionality affected Hispanic youth and communities, leading to unprecedented levels of trauma. This research responded to a need for a youth resiliency-building program in an urban and impoverished area with a majority Hispanic population. We conducted a formative evaluation of a youth intervention entitled Mind Matters: Overcoming Adversity and Building Resilience, which aims to help youth overcome adversity and to build resilience via psychoeducation and skill development. Just prior to the pandemic in the United States (August-December, 2019), youth (N=12) participated in Mind Matters as part of an after-school program. Immediately following, we utilized focus groups to solicit youth's perspectives on the acceptability of the program, what they had learned, content areas they liked best, and their recommendations for program improvement. Follow-up phone interviews were also conducted three months later (March 2020) while youth were at home as a result of the pandemic. Youth enjoyed the program and were able to apply skills learned to cope with stress in their daily lives and across ecological contexts. Findings point to the program as particularly well-suited to older adolescents. During the pandemic, most youth continued to utilize self-soothing and mindfulness skills to emotionally self-regulate while facing challenges related to home schooling. Findings highlight the importance of trauma-resiliency programming for youth and offer recommendations to practitioners utilizing the Mind Matters program.

So how special is special K? A systematic review and meta-analysis of ketamine for PTSD RCTs

Background: PTSD is a significant mental health problem worldwide. Current evidence-based interventions suffer various limitations. Ketamine is a novel agent that is hoped to be incrementally better than extant interventions.Objective: Several randomized control trials (RCTs) of ketamine interventions for PTSD have now been published. We sought to systematically review and meta-analyse results from these trials to evaluate preliminary evidence for ketamine's incremental benefit above-and-beyond control interventions in PTSD treatment.Results: Omnibus findings from 52 effect sizes extracted across six studies (n = 221) yielded a small advantage for ketamine over control conditions at reducing PTSD symptoms (g = 0.27, 95% CI = 0.03, 0.51). However, bias-correction estimates attenuated this effect (adjusted g = 0.20, 95%, CI = -0.08, 0.48). Bias estimates indicated smaller studies reported larger effect sizes favouring ketamine. The only consistent timepoint assessed across RCTs was 24-hours post-initial infusion. Effects at 24-hours post-initial infusion suggest ketamine has a small relative advantage over controls (g = 0.35, 95% CI = 0.06, 0.64). Post-hoc analyses at 24-hours post-initial infusion indicated that ketamine was significantly better than passive controls (g = 0.44, 95% CI = 0.03, 0.85), but not active controls (g = 0.24, 95% CI = -0.30, 0.78). Comparisons one-week into intervention suggested no meaningful group differences (g = 0.24, 95% CI = 0.00, 0.48). No significant differences were evident for RCTs that examined effects two-weeks post initial infusion (g = 0.17, 95% CI = -0.10, 0.44).Conclusions: Altogether, ketamine-for-PTSD RCTs reveal a nominal initial therapeutic advantage relative to controls. However, bias and heterogeneity appear problematic. While rapid acting effects were observed, all control agents (including saline) also evidenced rapid acting effects. We argue blind penetration to be a serious concern, and that placebo is the likely mechanism behind reported therapeutic effects.

Asylee perspectives on psychotherapies for posttraumatic stress

Asylees (i.e., asylum seekers) have a higher prevalence of mental health concerns, particularly posttraumatic distress, than the general population due to both their exposure to traumatic experiences and prolonged uncertain status in a new country. Meta-analyses of randomized controlled trials with asylees have found that culturally adapted cognitive behavioral therapy (CA-CBT), eye movement desensitization and reprocessing (EMDR), and narrative exposure therapy (NET) are efficacious in treating trauma-related symptoms and posttraumatic stress disorder (PTSD); however, treatment utilization remains low. Thus, it is imperative to determine what PTSD interventions are effective, credible, and acceptable for asylees. We employed structured virtual interviews with 40 U.S. asylees from diverse countries living with one or more symptoms of PTSD. Participants were asked about treatment engagement, perceived barriers to treatment, goals for psychotherapy, and perceptions of the effectiveness and difficulty of engaging in CA-CBT, EMDR, NET, and (non-exposure-based) interpersonal therapy (IPT) for PTSD. Participants perceived IPT to be significantly less difficult than all exposure-based treatments, with medium effect sizes, ds = 0.55-0.71. A qualitative analysis of asylees' comments provided valuable insights into how they think about these treatments. Ways in which these results can be considered when informing recommendations for improving interventions for asylees are discussed.

A randomized controlled trial of Deep Brain Reorienting: a neuroscientifically guided treatment for post-traumatic stress disorder

BACKGROUND

Advanced neuroscientific insights surrounding post-traumatic stress disorder (PTSD) and its associated symptomatology should beget psychotherapeutic treatments that integrate these insights into practice. Deep Brain Reorienting (DBR) is a neuroscientifically-guided psychotherapeutic intervention that targets the brainstem-level neurophysiological sequence that transpired during a traumatic event. Given that contemporary treatments have non-response rates of up to 50% and high drop-out rates of >18%, DBR is investigated as a putative candidate for effective treatment of some individuals with PTSD.

OBJECTIVE

To conduct an interim evaluation of the effectiveness of an eight-session clinical trial of videoconference-based DBR versus waitlist (WL) control for individuals with PTSD.

METHOD

Fifty-four individuals with PTSD were randomly assigned to DBR (N = 29) or WL (N = 25). At baseline, post-treatment, and three-month follow-up, participants' PTSD symptom severity was assessed using the Clinician Administered PTSD Scale (CAPS-5). This is an interim analysis of a clinical trial registered with the U. S. National Institute of Health (NCT04317820).

RESULTS

Significant between-group differences in CAPS-total and all subscale scores (re-experiencing, avoidance, negative alterations in cognitions/mood, alterations in arousal/reactivity) were found at post-treatment (CAPS-total: Cohen's d = 1.17) and 3-month-follow-up (3MFU) (CAPS-total: Cohen's d = 1.18). Significant decreases in CAPS-total and all subscale scores were observed within the DBR group pre - to post-treatment (36.6% CAPS-total reduction) and pre-treatment to 3MFU (48.6% CAPS-total reduction), whereas no significant decreases occurred in the WL group. After DBR, 48.3% at post-treatment and 52.0% at 3MFU no longer met PTSD criteria. Attrition was minimal with one participant not completing treatment; eight participants were lost to 3MFU.

CONCLUSIONS

These findings provide emerging evidence for the effectiveness of DBR as a well-tolerated treatment that is based on theoretical advances highlighting alterations to subcortical mechanisms in PTSD and associated symptomatology. Additional research utilizing larger sample sizes, neuroimaging data, and comparisons or adjacencies with other psychotherapeutic approaches is warranted.Trial registration: ClinicalTrials.gov identifier: NCT04317820..

Case report: Medical student types journals during ketamine infusions for suicidal ideation, treatment-resistant depression, post-traumatic stress disorder, and generalized anxiety disorder

Suicide is the most common cause of death in male resident physicians and the second most common cause of death in resident physicians overall. Physicians also experience high rates of major depressive disorder (MDD), post-traumatic stress disorder (PTSD), and burnout. These conditions frequently develop during medical school, and threaten not only physicians but the patients they care for. A 30-year-old medical student presented to our clinic with a history of treatment-resistant depression (TRD), generalized anxiety disorder (GAD), PTSD, and 5 years of daily suicidal ideation. Previous treatments included therapy, lifestyle modifications, and various combinations of six antidepressants. These interventions had little effect on the patient's mental health. The patient was treated at our clinic with an 8-month regimen of IV ketamine infusions and ketamine-assisted psychotherapy (KAP). The patient achieved remission from suicidality and PTSD within 1 month; and TRD and GAD within 7 months. The patient's Patient Health Questionnaire (PHQ-9) score decreased from 25 (severe depression) to 1 (not depressed). These findings suggest that ketamine and KAP may represent effective interventions for mental health applications in healthcare professionals. The patient made the unique decision to attempt to type narrative journals during four of his ketamine infusions (doses ranged from 1.8 to 2.1 mg/kg/h IV). The patient successfully typed detailed journals throughout each 1-h ketamine infusion. To our knowledge, these journals represent the first independently typed, first-person, real-time narratives of ketamine-induced non ordinary states of consciousness. The transcripts of these journals may provide useful insights for clinicians, particularly in the context of KAP.

The effectiveness of psychological interventions for reducing PTSD and psychological distress in first responders: A systematic review and meta-analysis

Background

First responders are faced with stressful and traumatic events in their work that may affect their psychological health. The current review examined the effectiveness of psychological interventions to treat posttraumatic stress disorder (PTSD), anxiety, depression, stress and burnout in first responders.

Methods

Four databases were searched to identify controlled studies that examined the efficacy of psychological interventions to reduce PTSD symptoms (primary outcome) in first responders (including firefighters, police/law enforcement officers, search and rescue personnel, emergency and paramedics teams). Secondary outcomes were anxiety, depression, burnout, and stress.

Results

15 studies were identified, including 10 studies that measured PTSD, 7 studies for anxiety, 10 studies for depression, 7 studies for stress and 1 for burnout. Interventions were associated with a significant reduction in PTSD (SDM = -0.86; 95% CI = -1.34 –- 0.39), depression (SDM = -0.63; 95% CI = -0.94 –-0.32), and anxiety (SDM = -0.38; 95% CI = -0.71 –-0.05) but not stress (SDM = -0.13; 95% CI = -0.51–0.25). CBT-based and clinician-delivered interventions were associated with significantly greater reductions in PTSD than other types of interventions and non-clinician interventions, but no differences were found for depression. There was evidence of moderate to high risk of bias across all studies.

Conclusions

Psychological interventions are effective in reducing PTSD, depression and anxiety symptoms but not stress in first responders. Further research is needed using high quality randomised designs over longer periods of follow-up.

Evaluation of a standardized posttraumatic stress disorder treatment framework in routine mental health care: Effectiveness and predictors of treatment outcome in a consecutive sample

The primary aim of the present study was to evaluate the effectiveness of standardized care package (CP) treatment for posttraumatic stress disorder (PTSD) in a Danish sample of adult psychiatric outpatients (N = 948). Secondary aims were to identify baseline predictors of treatment outcomes and investigate between-group differences in outcomes with regard to sex and treatment modality (i.e., group vs. individual therapy). The naturalistic, nonrandomized study followed a pre-post design. Patient data from five psychiatric outpatient clinics were collected between March 2011 and November 2017. Data were drawn from self-report questionnaires (i.e., SCL-90-R, WHO-5, BHS) and therapist-reported measures (i.e., GAF-S, GAF-F) administered at baseline and posttreatment. Between-group effects for sex and therapy modality (group vs. individual) were analyzed using analyses of variance, and possible predictors of outcomes were selected through LASSO regression and analyzed via hierarchical regression. Pre-post effects were small to moderate, ds = 0.39-0.69. No differences emerged regarding treatment modality, but women had significantly better outcomes than men. Aside from sex, only baseline symptom severity predicted outcomes. The effectiveness of the CP treatment was generally limited, indicating the need to implement improved therapeutic practices, such as the use of evidence-based treatments, and to provide better training to mental health clinicians. The findings underscore the need for further comparisons of group and individual treatment modalities using evidence-based therapies as well as the need to investigate factors that may affect treatment outcome.

An in-Vivo Daily Self-Report Approach to the Assessment of Outcomes of Two Psychotherapies for Women With Posttraumatic Stress Disorder

Emotion regulation and interpersonal psychotherapies that do not require trauma memory processing have been shown to be effective in treating posttraumatic stress disorder (PTSD). This study used a novel method to assess in vivo outcomes in a randomized clinical trial with women (N = 147; ages 18-54; 61% of color; 94% low income) with full (79%) or partial (21%) PTSD. Participants were assigned to affect regulation or interpersonal therapy, or wait-list, and completed daily self-reports for 2 to 4 weeks at baseline and up to 30 days at posttest. Mixed model regression analyses tested pre-post change on five factor analytically derived aggregated daily self-report scores. Emotion regulation-focused therapy was associated with reduced PTSD symptoms, dysregulation, and negative affect, and improvement in adaptive self-regulation and positive affect. Interpersonal-focused therapy was associated with reduced PTSD symptoms and dysregulation. Although both therapies were associated with reduced PTSD symptoms, whether this was due to nonspecific factors rather than the treatments per se could not be determined. Daily self-report data warrant further investigation in psychotherapy research with disorders such as PTSD, in order to assess affective and interpersonal dysregulation and adaptive regulation as they occur in daily life.

Contemporary Supportive Therapy: A Review of History, Theory, and Evidence

Supportive psychotherapy interventions were developed as a part of psychodynamic psychotherapy work, and supportive psychotherapy was historically considered to be the default form of therapy only for lower-functioning patients. These roots unfortunately have resulted in supportive psychotherapy being viewed as an inferior form of treatment. In reality, supportive psychotherapy is a practical and flexible form of psychotherapy that helps patients with a wide range of psychiatric illnesses, including mood disorders, anxiety disorders, posttraumatic stress disorder, schizophrenia, personality disorders, eating disorders, body dysmorphic disorder, and substance use disorders. In addition, supportive psychotherapy can be well-suited to higher-functioning patients, as well as to patients who are chronically lower-functioning. There is also evidence to support the use of supportive psychotherapy in patients with certain medical illnesses, including coronary artery disease, some gastrointestinal illnesses, HIV infection, and certain types of cancer. The goals of supportive psychotherapy include helping patients to understand emotional experiences, improving affective regulation and reality-testing, making use of their most effective coping strategies, and engaging in collaborative problem solving to reduce stressors and increase effective engagement with support systems.

Efficacy and acceptability of interventions for co-occurring PTSD and SUD: A meta-analysis

Over the past 20 years, numerous treatments addressing comorbid Posttraumatic Stress Disorder (PTSD) and Substance Use Disorder (SUD) have been developed and tested. The current meta-analysis examined the efficacy and acceptability of the two central treatment types- trauma-focused and non-trauma-focused - compared with all comparators and with cognitive-behavioral manualized SUD treatments immediately post-treatment and at longest follow-up. Twenty-eight randomized clinical trials (N = 3247) were included. There were small to large within-group effects for all forms of active treatment (gs = 0.30-1.11). Trauma-focused but not non-trauma-focused treatments outperformed all comparators on PTSD outcomes at post-treatment. Neither trauma-focused nor non-trauma-focused treatment outperformed all comparators on SUD outcomes at post-treatment. Neither trauma- nor non-trauma-focused treatment outperformed manualized SUD treatments on PTSD outcomes at either time point. Manualized SUD treatments outperformed trauma-focused treatments on SUD outcomes at post-treatment and non-trauma-focused treatments on PTSD outcomes at follow-up. Regarding treatment retention, neither trauma-focused nor non-trauma-focused treatments significantly differed from all comparators or from manualized SUD treatments. Between-group results were largely unchanged in trim-and-fill analyses, but were not robust to fail-safe N. Few moderators were detected. Taken together, results suggest that trauma-focused, non-trauma-focused, and manualized SUD interventions are sound options for individuals with comorbid PTSD/SUD.

Individual Differences in Conditioned Fear and Extinction in Female Rats

The inability to extinguish a traumatic memory is a key aspect of post-traumatic stress disorder (PTSD). While PTSD affects 10–20% of individuals who experience a trauma, women are particularly susceptible to developing the disorder. Despite this notable female vulnerability, few studies have investigated this particular resistance to fear extinction observed in females. Similar to humans, rodent models of Pavlovian fear learning and extinction show a wide range of individual differences in fear learning and extinction, although female rodents are considerably understudied. Therefore, the present study examined individual differences in fear responses, including freezing behavior and ultrasonic vocalizations (USVs), of female Long–Evans rats during acquisition of fear conditioning and cued fear extinction. Similar to prior studies in males, female rats displayed individual variation in freezing during cued fear extinction and were divided into extinction competent (EC) and extinction resistant (ER) phenotypes. Differences in freezing between ER and EC females were accompanied by shifts in rearing during extinction, but no darting was seen in any trial. Freezing behavior during fear learning did not differ between the EC and ER females. Vocalizations emitted in the 22 and 50 kHz ranges during fear learning and extinction were also examined. Unlike vocalizations seen in previous studies in males, very few 22 kHz distress vocalizations were emitted by female rats during fear acquisition and extinction, with no difference between ER and EC groups. Interestingly, all female rats produced significant levels of 50 kHz USVs, and EC females emitted significantly more 50 kHz USVs than ER rats. This difference in 50 kHz USVs was most apparent during initial exposure to the testing environment. These results suggest that like males, female rodents show individual differences in both freezing and USVs during fear extinction, although females appear to vocalize more in the 50 kHz range, especially during initial periods of exposure to the testing environment, and emit very few of the 22 kHz distress calls that are typically observed in males during fear learning or extinction paradigms. Overall, these findings show that female rodents display fear behavior repertoires divergent from males.

Long-term outcomes of psychological treatment for posttraumatic stress disorder: a systematic review and meta-analysis

Several types of psychological treatment for posttraumatic stress disorder (PTSD) are considered well established and effective, but evidence of their long-term efficacy is limited. This systematic review and meta-analysis aimed to investigate the long-term outcomes across psychological treatments for PTSD. MEDLINE, Cochrane Library, PTSDpubs, PsycINFO, PSYNDEX, and related articles were searched for randomized controlled trials with at least 12 months of follow-up. Twenty-two studies (N = 2638) met inclusion criteria, and 43 comparisons of cognitive behavioral therapy (CBT) were available at follow-up. Active treatments for PTSD yielded large effect sizes from pretest to follow-up and a small controlled effect size compared with non-directive control groups at follow-up. Trauma-focused treatment (TFT) and non-TFT showed large improvements from pretest to follow-up, and effect sizes did not significantly differ from each other. Active treatments for comorbid depressive symptoms revealed small to medium effect sizes at follow-up, and improved PTSD and depressive symptoms remained stable from treatment end to follow-up. Military personnel, low proportion of female patients, and self-rated PTSD measures were associated with decreased effect sizes for PTSD at follow-up. The findings suggest that CBT for PTSD is efficacious in the long term. Future studies are needed to determine the lasting efficacy of other psychological treatments and to confirm benefits beyond 12-month follow-up.

Examination of Initial Evidence for EMDR as a Treatment for Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) is a debilitating psychological condition that impacts millions of people globally. The front-line psychological intervention for OCD is exposure/response prevention (ERP), however, many individuals do not respond to this treatment approach. Eye movement desensitization and reprocessing (EMDR) is a new therapeutic option which could be effective in treating OCD. This review examined the initial evidence for the effectiveness of EMDR in reducing OCD symptoms. Nine studies were included in the review, including six case studies and three group studies. Results indicate that EMDR is a promising candidate for treating OCD, with all studies showing EMDR therapy resulted in reduced symptoms from baseline. Results also indicated that EMDR may be as effective as ERP, and more effective than selective serotonin reuptake inhibitors (SSRIs) in treating OCD.

Cannabis use and posttraumatic stress disorder comorbidity: Epidemiology, biology and the potential for novel treatment approaches

Cannabis use is increasing among some demographics in the United States and is tightly linked to anxiety, trauma, and stress reactivity at the epidemiological and biological level. Stress-coping motives are highly cited reasons for cannabis use. However, with increased cannabis use comes the increased susceptibility for cannabis use disorder (CUD). Indeed, CUD is highly comorbid with posttraumatic stress disorder (PTSD). Importantly, endogenous cannabinoid signaling systems play a key role in the regulation of stress reactivity and anxiety regulation, and preclinical data suggest deficiencies in this signaling system could contribute to the development of stress-related psychopathology. Furthermore, endocannabinoid deficiency states, either pre-existing or induced by trauma exposure, could provide explanatory insights into the high rates of comorbid cannabis use in patients with PTSD. Here we review clinical and preclinical literature related to the cannabis use-PTSD comorbidity, the role of endocannabinoids in the regulation of stress reactivity, and potential therapeutic implications of recent work in this area.

The Contribution of Common and Specific Therapeutic Factors to Mindfulness-Based Intervention Outcomes

While Mindfulness-Based Interventions (MBIs) have been shown to be effective for a range of patient populations and outcomes, a question remains as to the role of common therapeutic factors, as opposed to the specific effects of mindfulness practice, in contributing to patient improvements. This project used a mixed-method design to investigate the contribution of specific (mindfulness practice-related) and common (instructor and group related) therapeutic factors to client improvements within an MBI. Participants with mild-severe depression (N = 104; 73% female, M age = 40.28) participated in an 8-week MBI. Specific therapeutic factors (formal out-of-class meditation minutes and informal mindfulness practice frequency) and social common factors (instructor and group ratings) were entered into multilevel growth curve models to predict changes in depression, anxiety, stress, and mindfulness at six timepoints from baseline to 3-month follow-up. Qualitative interviews with participants provided rich descriptions of how instructor and group related factors played a role in therapeutic trajectories. Findings indicated that instructor ratings predicted changes in depression and stress, group ratings predicted changes in stress and self-reported mindfulness, and formal meditation predicted changes in anxiety and stress, while informal mindfulness practice did not predict client improvements. Social common factors were stronger predictors of improvements in depression, stress, and self-reported mindfulness than specific mindfulness practice-related factors. Qualitative data supported the importance of relationships with instructor and group members, involving bonding, expressing feelings, and instilling hope. Our findings dispel the myth that MBI outcomes are exclusively the result of mindfulness meditation practice, and suggest that social common factors may account for much of the effects of these interventions. Further research on meditation should take into consideration the effects of social context and other common therapeutic factors.

Psychedelics and Psychotherapy

Psychedelics have shown great promise in modern clinical trials for treating various psychiatric conditions. As a transdiagnostic treatment that exerts its effects through subjective experiences that leave enduring effects, it is akin to psychotherapy. To date, there has been insufficient discussion of how psychedelic therapy is similar to and different from conventional psychotherapy. In this article, we review the shared features of effective conventional psychotherapies and situate therapeutic psychedelic effects within those. We then discuss how psychedelic drug effects might amplify conventional psychotherapeutic processes-particularly via effects on meaning and relationship-as well as features that make psychedelic treatment unique. Taking into account shared features of conventional psychotherapies and unique psychedelic drug effects, we create a framework for understanding why psychedelics are likely to be effective with very diverse types of psychotherapies. We also review the formal psychotherapies that have been adjunctively included in modern psychedelic trials and extend the understanding of psychedelics as psychotherapy towards implications for clinical ethics and trial design. We aim to provide some common conceptual vocabulary that can be used to frame therapeutic psychedelic effects beyond the confines of any one specific modality.

PTSD / substance use disorder comorbidity: Treatment options and public health needs

Purpose of Review

Posttraumatic stress disorder (PTSD) commonly co-occurs with substance use disorder (SUD) and is challenging to treat. We review all behavioral therapy models with at least one randomized controlled trial in a current PTSD/SUD population. We identify factors in selecting a model for clinical use, emphasizing a public health framework that balances the need for evidence with the need for feasibility in frontline settings.

Recent Findings

Seven published models and 6 unpublished models are reviewed. Public health considerations for choosing a model include: whether it's been studied across a broad range of SUDs and in complex SUD patients; whether it can be conducted in group modality; its appeal to patients and providers; its cost; workforce requirements; and its ability to reduce substance use in addition to PTSD.

Summary

There are two broad types of models: those that originated in the PTSD field versus the SUD field. Overall, the latter are stronger on public health factors and more feasible in SUD settings. Published models in this category include Relapse Prevention, BRENDA, and Seeking Safety. PTSD/SUD research is at an early stage and there is a need for methodology that quantifies "level of burden" (patients' socioeconomic disadvantages) across trials.

Electroencephalography-based neurofeedback as treatment for post-traumatic stress disorder: A systematic review and meta-analysis

Background.

Post-traumatic stress disorder (PTSD) is debilitating for patients and society. There are a number of treatment methods albeit not all patients respond to these and an interesting method using electroencephalography-based neurofeedback (EEG-NF) has become more prominent in recent years. This systematic review aimed to assess whether EEG-NF, compared with sham NF, other treatment, or no treatment, is effective for PTSD. Primary outcomes were self-harm, PTSD symptoms, level of functioning and health-related quality of life.

Methods.

Systematic literature searches for randomized controlled trials (RCTs) were conducted in six databases. Random effects meta-analysis was performed. Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation.

Results.

Four RCTs were included (123 participants). Suicidal thoughts were significantly reduced after EEG-NF compared with a waiting list in a small study. PTSD symptoms were assessed in all studies with different instruments. Results were consistently in favor of EEG-NF with large effect sizes (standardized mean difference −2.30 (95% confidence interval: −4.37 to −0.24). One study reported significantly improved level of executive functioning and one study a reduction in use of psychotropic medication. Complications were scarcely reported. Certainty of evidence was assessed as very low for the four assessed outcomes.

Conclusions.

Based on four RCTs, with several study limitations and imprecision, it is uncertain whether EEG-NF reduces suicidal thoughts, PTSD symptoms, medication use, or improves function. Although all studies showed promising results, further studies are needed to increase the certainty of evidence.

Allegiance Bias and Treatment Quality as Moderators of the Effectiveness of Humanistic Psychotherapy: Protocol for a Systematic Review and Meta-Analysis

Background

In many countries, humanistic psychotherapy (HPT) is viewed as a broad psychotherapeutic approach and is accepted in health care systems. To qualify for reimbursement by health insurance in Germany, psychotherapy approaches have to be evaluated positively by the German Scientific Board of Psychotherapy (GSBP). The GSBP examined HPT and its subapproaches based on an application by a number of professional organizations affiliated with HPT (Work Group Humanistic Psychotherapy, WGHPT). The GSBP came to the decision that none of the HPT subapproaches provided sufficient evidence to be evaluated as evidence based. Potential reasons for the discrepancy between international recognition of HPT and GSBP’s decision will be explored: researchers’ allegiance may have led to a risk of bias disadvantaging HPT. Furthermore, the evaluation criteria of the GSBP did not systematically consider whether HPT was conceptualized bona fide and implemented with sufficient treatment integrity in the studies.

Objective

This systematic review will re-examine the studies included in the review of the GSBP. Within 2 comparisons (HPT vs control and HPT vs other psychotherapeutic interventions), we will examine moderating effects of treatment quality (bona fide and treatment integrity) and allegiance on the effectiveness of HPT.

Methods

This review is based on the prior systematic review by the GSBP. The GSBP examined randomized controlled trials (RCTs) and studies with non-RCTs of HPT interventions for individuals with mental disorders. All studies suggested by the WGHPT were included; moreover, the GSBP conducted searches in standard electronic databases (Cochrane Central Register of Controlled Trials, MEDLINE, PsycINFO, and PSYNDEX) and handsearches in relevant systematic reviews and contacted experts. A total of 2 independent GSBP reviewers performed study screening using a structured form. On the basis of the prior work of the GSBP, all studies that were positively screened by the GSBP will be included in this review. Data will be extracted independently by 4 authors. Standardized mean difference will be calculated, and possible publication bias will be tested using funnel plots and Egger test. A priori defined subgroup or meta-regression analyses will be performed for treatment quality, allegiance, type of nonactive control, study quality, type of subapproach, and target population (children and adolescents or adults).

Results

The GSBP identified 115 eligible studies that will be reanalyzed in this systematic review.

Conclusions

Results about moderator effects of treatment quality and allegiance will provide important information about their impact on the evaluation of HPT and other psychotherapy approaches and can be used for further evaluation methods.

Trauma-Focused Presence

The purpose of this article is to capture and illuminate a trauma-focused presence in psychotherapy treatment. The goal is to highlight an integrative approach that centers on the trauma survivor’s battle with freedom and limitation. Both the expansive and the constrictive tendencies of many traumatized clients are exemplified, focusing on the dichotomous or polarized positions that clients present. Key factors of evidence-based therapeutic relationships that can guide therapist stances and engagement efforts are explored. This approach moves away from an overemphasis on and strict adherence to the medical model framework and toward a contextual standard grounded in a humanistic blanket and characterized by a person-centered and relationally driven therapeutic approach. The trauma therapist chiefly fosters engagement and makes space or pathways for an assortment of therapeutic interventions that are congruent with the client’s theory of change and take shape organically. Developing intrapersonal and interpersonal presence are primary focal points that correlate with the importance of personal and interactive processes in successful psychotherapy outcome research. Meaning making is at the core of a trauma-focused presence and takes place through client and therapist dialogue.

Psychological interventions for ICD-11 complex PTSD symptoms: systematic review and meta-analysis

BACKGROUND

The 11th revision to the WHO International Classification of Diseases (ICD-11) identified complex post-traumatic stress disorder (CPTSD) as a new condition. There is a pressing need to identify effective CPTSD interventions.

METHODS

We conducted a systematic review and meta-analysis of randomised controlled trials (RCTs) of psychological interventions for post-traumatic stress disorder (PTSD), where participants were likely to have clinically significant baseline levels of one or more CPTSD symptom clusters (affect dysregulation, negative self-concept and/or disturbed relationships). We searched MEDLINE, PsycINFO, EMBASE and PILOTS databases (January 2018), and examined study and outcome quality.

RESULTS

Fifty-one RCTs met inclusion criteria. Cognitive behavioural therapy (CBT), exposure alone (EA) and eye movement desensitisation and reprocessing (EMDR) were superior to usual care for PTSD symptoms, with effects ranging from g = -0.90 (CBT; k = 27, 95% CI -1.11 to -0.68; moderate quality) to g = -1.26 (EMDR; k = 4, 95% CI -2.01 to -0.51; low quality). CBT and EA each had moderate-large or large effects on negative self-concept, but only one trial of EMDR provided useable data. CBT, EA and EMDR each had moderate or moderate-large effects on disturbed relationships. Few RCTs reported affect dysregulation data. The benefits of all interventions were smaller when compared with non-specific interventions (e.g. befriending). Multivariate meta-regression suggested childhood-onset trauma was associated with a poorer outcome.

CONCLUSIONS

The development of effective interventions for CPTSD can build upon the success of PTSD interventions. Further research should assess the benefits of flexibility in intervention selection, sequencing and delivery, based on clinical need and patient preferences.

Common Factors: What Are They and What Do They Mean for Humanistic Psychology?

Although common factors have been widely discussed in the clinical literature, the two questions addressed in this article remain relevant: (a) What are the common factors? (b) What do they mean for humanistic psychology? The first question is important because there is no “definitive list” of common factors, and lists presented in the literature often differ dramatically. In response to this question, the article suggests that an evidence-based list of nine common factors by Wampold provides a useful and credible list. The second question is also important, particularly to humanistic psychologists. Among other answers, the article shows that research findings on common factors provide scientific support for humanistic psychology’s emphasis on the importance of the human and relational factors in psychotherapy.

A methodological review of meta-analyses of the effectiveness of clinical psychology treatments

This article presents a methodological review of 54 meta-analyses of the effectiveness of clinical psychological treatments, using standardized mean differences as the effect size index. We statistically analyzed the distribution of the number of studies of the meta-analyses, the distribution of the sample sizes in the studies of each meta-analysis, the distribution of the effect sizes in each of the meta-analyses, the distribution of the between-studies variance values, and the Pearson correlations between effect size and sample size in each meta-analysis. The results are presented as a function of the type of standardized mean difference: posttest standardized mean difference, standardized mean change from pretest to posttest, and standardized mean change difference between groups. These findings will help researchers design future Monte Carlo and theoretical studies on the performance of meta-analytic procedures, based on the manipulation of realistic model assumptions and parameters of the meta-analyses. Furthermore, the analysis of the distribution of the mean effect sizes through the meta-analyses provides a specific guide for the interpretation of the clinical significance of the different types of standardized mean differences within the field of the evaluation of clinical psychological interventions.

Posttraumatic stress disorder: a model of the longitudinal course and the role of risk factors

Posttraumatic stress disorder (PTSD) differs from other anxiety disorders in that experience of a traumatic event is necessary for the onset of the disorder. The condition runs a longitudinal course, involving a series of transitional states, with progressive modification occurring with time. Notably, only a small percentage of people that experience trauma will develop PTSD. Risk factors, such as prior trauma, prior psychiatric history, family psychiatric history, peritraumatic dissociation, acute stress symptoms, the nature of the biological response, and autonomic hyperarousal, need to be considered when setting up models to predict the course of the condition. These risk factors influence vulnerability to the onset of PTSD and its spontaneous remission. In the majority of cases, PTSD is accompanied by another condition, such as major depression, an anxiety disorder, or substance abuse. This comorbidity can also complicate the course of the disorder and raises questions about the role of PTSD in other psychiatric conditions. This article reviews what is known about the emergence of PTSD following exposure to a traumatic event using data from clinical studies.

First-line therapy for post-traumatic stress disorder: A systematic review of cognitive behavioural therapy and psychodynamic approaches

BACKGROUND

Despite evidence supporting cognitive behavioural therapy (CBT)-based interventions as the most effective approach for treating post-traumatic stress disorder (PTSD) in randomised control trials, alternative treatment interventions are often used in clinical practice. Psychodynamic (PDT)-based interventions are one example of such preferred approaches, this is despite comparatively limited available evidence supporting their effectiveness for treating PTSD.

AIMS

Existing research exploring effective therapeutic interventions for PTSD includes trauma-focused CBT involving exposure techniques. The present review sought to establish the treatment efficacy of CBT and PDT approaches and considers the potential impact of selecting PDT-based techniques over CBT-based techniques for the treatment of PTSD.

RESULTS

The evidence reviewed provided examples supporting PDT-based therapy as an effective treatment for PTSD, but confirmed CBT as more effective in the treatment of this particular disorder. Comparable dropout rates were reported for both treatment approaches, suggesting that relative dropout rate should not be a pivotal factor in the selection of a PDT approach over CBT for treatment of PTSD.

CONCLUSION/IMPLICATIONS

The need to routinely observe evidence-based recommendations for effective treatment of PTSD is highlighted and factors undermining practitioner engagement with CBT-based interventions for the treatment of PTSD are identified.

Individual treatment selection for patients with posttraumatic stress disorder

BACKGROUND

Trauma-focused cognitive behavioral therapy (Tf-CBT) and eye movement desensitization and reprocessing (EMDR) are two highly effective treatment options for posttraumatic stress disorder (PTSD). Yet, on an individual level, PTSD patients vary substantially in treatment response. The aim of the paper is to test the application of a treatment selection method based on a personalized advantage index (PAI).

METHOD

The study used clinical data for patients accessing treatment for PTSD in a primary care mental health service in the north of England. PTSD patients received either EMDR (N = 75) or Tf-CBT (N = 242). The Patient Health Questionnaire (PHQ-9) was used as an outcome measure for depressive symptoms associated with PTSD. Variables predicting differential treatment response were identified using an automated variable selection approach (genetic algorithm) and afterwards included in regression models, allowing the calculation of each patient's PAI.

RESULTS

Age, employment status, gender, and functional impairment were identified as relevant variables for Tf-CBT. For EMDR, baseline depressive symptoms as well as prescribed antidepressant medication were selected as predictor variables. Fifty-six percent of the patients (n = 125) had a PAI equal or higher than one standard deviation. From those patients, 62 (50%) did not receive their model-predicted treatment and could have benefited from a treatment assignment based on the PAI.

CONCLUSIONS

Using a PAI-based algorithm has the potential to improve clinical decision making and to enhance individual patient outcomes, although further replication is necessary before such an approach can be implemented in prospective studies.

A Non-randomized Controlled Trial of EMDR on Affective Symptoms in Patients With Glioblastoma Multiforme

Glioblastoma multiforme (GBM) is a highly aggressive brain cancer and its survival after diagnosis is less than 2 years. Therefore, GBM patients are especially prone to co-occurring psychological conditions such as anxiety and depressive disorders. Furthermore, aggressive medical therapies affect patients' lives, undermining their sense of meaning and coherence. The main aim of this study was to determine the effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) therapy on anxiety, depression and sense of coherence in patients with GBM. Thirty-seven GBM-diagnosed women were included in this trial and received standard medical care. Of those, 18 patients were treated during 4 months with 10-12 individual EMDR sessions (60-90 minutes each). Nineteen GBM patients were used as a non-randomized control group as they consented to psychological evaluations but not to a psychotherapeutic intervention. The groups were homogeneous in terms of gender, age, educational level and treatment, but not in anxiety and depressive levels at baseline. All patients were evaluated at baseline, after treatment (4 months) and at follow-up (further 4 months) by the Hospital Anxiety and Depression Scale (HADS-M) and the Sense of Coherence Scale (SOC-29). Caregivers in both groups were interviewed by the Patient Caregiver Questionnaire after 4 months follow-up. Statistical analyses were conducted using ANOVA statistics, correlation and regression analysis. Results showed a statistically significant decrease in the EMDR group in anxiety, depression and anger, when compared to the experimental group. EMDR therapy also had a positive impact upon the sense of coherence level in the experimental group, whereas in the control group this declined. Finally, the caregivers reported beneficial outcomes of the EMDR therapy with less anxiety- and anger-related behaviors in patients in the experimental group compared to the control group. This study is the first to show beneficial effects of EMDR therapy in alleviating affective symptoms and improving coherence in a severe medically ill population with GBM.

Treatment expectancy, working alliance, and outcome of Trauma-Focused Cognitive Behavioral Therapy with children and adolescents

BACKGROUND

It has been shown that positive treatment expectancy (TE) and good working alliance increase psychotherapeutic success in adult patients, either directly or mediated by other common treatment factors like collaboration. However, the effects of TE in psychotherapy with children, adolescents and their caregivers are mostly unknown. Due to characteristics of the disorder such as avoidant behavior, common factors may be especially important in evidence-based treatment of posttraumatic stress symptoms (PTSS), e.g. for the initiation of exposure based techniques.

METHODS

TE, collaboration, working alliance and PTSS were assessed in 65 children and adolescents (age M = 12.5; SD = 2.9) and their caregivers. Patients' and caregivers' TE were assessed before initiation of Trauma-Focused Cognitive Behavioral Therapy (TF-CBT). Patients' and caregivers' working alliance, as well as patients' collaboration were assessed at mid-treatment, patients' PTSS at pre- and post-treatment. Path analysis tested both direct and indirect effects (by collaboration and working alliance) of pre-treatment TE on post-treatment PTSS, and on PTSS difference scores.

RESULTS

Patients' or caregivers' TE did not directly predict PTSS after TF-CBT. Post-treatment PTSS was not predicted by patients' or caregivers' TE via patients' collaboration or patients' or caregivers' working alliance. Caregivers' working alliance with therapists significantly contributed to the reduction of PTSS in children and adolescents (post-treatment PTSS: β = - 0.553; p < 0.001; PTSS difference score: β = 0.335; p = 0.031).

CONCLUSIONS

TE seems less important than caregivers' working alliance in TF-CBT for decreasing PTSS. Future studies should assess TE and working alliance repeatedly during treatment and from different perspectives to understand their effects on outcome. The inclusion of a supportive caregiver and the formation of a good relationship between therapists and caregivers can be regarded as essential for treatment success in children and adolescents with PTSS.

Development of a novel, integrated cognitive-behavioral therapy for co-occurring posttraumatic stress and substance use disorders: A pilot randomized clinical trial

Posttraumatic stress disorder (PTSD) and substance use disorders (SUD) are complex psychiatric conditions that commonly co-occur. No evidence-based, 'gold standard' treatments for PTSD/SUD comorbidity are currently available. The present pilot randomized clinical trial was designed to evaluate the feasibility and preliminary efficacy of a novel, integrated cognitive-behavioral treatment approach for PTSD/SUD, entitled Treatment of Integrated Posttraumatic Stress and Substance Use (TIPSS), as compared to standard cognitive-behavioral treatment (CBT) for SUD. The TIPSS program integrates cognitive processing therapy with CBT for SUD for the treatment of co-occurring PTSD/SUD. Both treatment conditions are comprised of 12, 60-minute individual psychotherapy sessions, delivered twice-weekly over six weeks. Primary aims examine whether TIPSS, compared to standard CBT for SUD, reduces: (1) PTSD symptoms and (2) substance use outcomes (i.e., self-report, objective). Secondary aims examine whether (a) trauma- and substance cue reactivity and (b) distress tolerance (i.e., actual or perceived ability to withstand uncomfortable emotional or physical states) are significant mechanisms of change. The study was recently closed to new enrollment. Participants included adults with substance dependence and at least four symptoms of PTSD.

"Gold Standards," Plurality and Monocultures: The Need for Diversity in Psychotherapy

For psychotherapy of mental disorders, presently several approaches are available, such as interpersonal, humanistic, systemic, psychodynamic or cognitive behavior therapy (CBT). Pointing to the available evidence, proponents of CBT claim that CBT is the gold standard. Some authors even argue for an integrated CBT-based form of psychotherapy as the only form of psychotherapy. CBT undoubtedly has its strengths and CBT researchers have to be credited for developing and testing treatments for many mental disorders. A critical review, however, shows that the available evidence for the theoretical foundations of CBT, assumed mechanisms of change, quality of studies, and efficacy is not as robust as some researchers claim. Most important, there is no consistent evidence that CBT is more efficacious than other evidence-based approaches. These findings do not justify regarding CBT as the gold standard psychotherapy. They even provide less justification for the idea that the future of psychotherapy lies in one integrated CBT-based form of psychotherapy as the only type of psychotherapy. For the different psychotherapeutic approaches a growing body of evidence is available. These approaches have their strengths because of differences in their respective focus on interpersonal relationships, affects, cognitions, systemic perspectives, experiential, or unconscious processes. Different approaches may be suitable to different patients and therapists. As generally assumed, progress in research results from openness to new ideas and learning from diverse perspectives. Thus, different forms of evidence-based psychotherapy are required. Plurality is the future of psychotherapy, not a uniform "one fits all" approach.

EMDR beyond PTSD: A Systematic Literature Review

Background: Eye Movement Desensitization and Reprocessing (EMDR) is a psychotherapeutic approach that has demonstrated efficacy in the treatment of Post-traumatic Stress Disorder (PTSD) through several randomized controlled trials (RCT). Solid evidence shows that traumatic events can contribute to the onset of severe mental disorders and can worsen their prognosis. The aim of this systematic review is to summarize the most important findings from RCT conducted in the treatment of comorbid traumatic events in psychosis, bipolar disorder, unipolar depression, anxiety disorders, substance use disorders, and chronic back pain.

Methods: Using PubMed, ScienceDirect, and Scopus, we conducted a systematic literature search of RCT studies published up to December 2016 that used EMDR therapy in the mentioned psychiatric conditions.

Results: RCT are still scarce in these comorbid conditions but the available evidence suggests that EMDR therapy improves trauma-associated symptoms and has a minor effect on the primary disorders by reaching partial symptomatic improvement.

Conclusions: EMDR therapy could be a useful psychotherapy to treat trauma-associated symptoms in patients with comorbid psychiatric disorders. Preliminary evidence also suggests that EMDR therapy might be useful to improve psychotic or affective symptoms and could be an add-on treatment in chronic pain conditions.

Somatic Experiencing for Posttraumatic Stress Disorder: A Randomized Controlled Outcome Study

This study presents the first known randomized controlled study evaluating the effectiveness of somatic experiencing (SE), an integrative body-focused therapy for treating people with posttraumatic stress disorder (PTSD). There were 63 participants meeting DSM-IV-TR full criteria for PTSD included. Baseline clinical interviews and self-report measures were completed by all participants, who were then randomly assigned to study (n = 33) or waitlist (n = 30) groups. Study participants began 15 weekly SE sessions, whereas waitlist participants waited the same period, after which the second evaluation was conducted. All participants were evaluated a third time after an additional 15 weeks, during which time the waitlist group received SE therapy. Pretreatment evaluation showed no significant differences between groups. Mixed model linear regression analysis showed significant intervention effects for posttraumatic symptoms severity (Cohen's d = 0.94 to 1.26) and depression (Cohen's d = 0.7 to 1.08) both pre-post and pre-follow-up. This randomized controlled study of SE shows positive results indicating SE may be an effective therapy method for PTSD. Further research is needed to understand who shall benefit most from this treatment modality.

Concurrent Treatment with Prolonged Exposure for Co-Occurring Full or Subthreshold Posttraumatic Stress Disorder and Substance Use Disorders: A Randomized Clinical Trial

BACKGROUND

To test whether an integrated prolonged exposure (PE) approach could address posttraumatic stress disorder (PTSD) symptoms effectively in individuals with co-occurring substance use disorders (SUD), we compared concurrent treatment of PTSD and SUD using PE (COPE) to relapse prevention therapy (RPT) for SUD and an active monitoring control group (AMCG).

METHODS

We conducted a randomized 12-week trial with participants (n = 110; 64% males; 59% African Americans) who met Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision criteria for full or subthreshold PTSD and SUD. Participants were randomly assigned to COPE (n = 39), RPT (n = 43), or AMCG (n = 28).

RESULTS

At the end-of-treatment, COPE and RPT demonstrated greater reduction in PTSD symptom severity relative to AMCG (COPE-AMCG = -34.06, p < 0.001; RPT-AMCG = -22.58, p = 0.002). Although the difference between COPE and RPT was not significant in the complete sample, the subset of participants with full (vs. subthreshold) PTSD demonstrated significantly greater reduction of PTSD severity in COPE relative to RPT. Both treatments were superior to AMCG in reducing the days of primary substance use (COPE-AMCG = -0.97, p = 0.01; RPT-AMCG = -2.07, p < 0.001). Relative to COPE, RPT showed significantly more improvement in SUD outcome at end-of-treatment (RPT-COPE = -1.10, p = 0.047). At 3-month follow-up, COPE and RPT maintained their treatment gains and were not significantly different in PTSD severity or days of primary substance use.

CONCLUSION

COPE and RPT reduced PTSD and SUD severity in participants with PTSD + SUD. Findings suggest that among those with full PTSD, COPE improves PTSD symptoms more than a SUD-only treatment. The use of PE for PTSD was associated with significant decreases in PTSD symptoms without worsening of substance use.
