The effects of an intensive outpatient treatment for PTSD.

Introduction: Research has shown that combining different evidence-based PTSD treatments for patients with PTSD in an intensive inpatient format seems to be a promising approach to enhance efficiency and reduce generally high dropout rates.Objective: To assess the effectiveness of an intensive six-day outpatient trauma-focused treatment for patients with PTSD.Method: Data from 146 patients (89.7% female, mean age = 36.79, SD = 11.31) with PTSD due to multiple traumatization were included in the analyses. The treatment programme consisted of six days of treatment within two weeks, with two daily individual 90-minute trauma-focused sessions (prolonged exposure and eye movement desensitization and reprocessing), one hour of exercise, and one hour of psychoeducation. All participants experienced multiple traumas, and 85.6% reported one or more comorbid psychiatric disorders. PTSD symptoms and diagnoses were assessed with the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), and self-reported symptoms were assessed with the PTSD Checklist for DSM-5 (PCL-5).Results: A significant decline in PTSD symptoms (CAPS-5 and PCL-5) from pretreatment to one-month follow-up (Cohen's d = 1.13 and 1.59) was observed and retained at six-month follow-up (Cohen's d = 1.47 and 1.63). After one month, 52.4% of the patients no longer met the diagnostic criteria for PTSD (CAPS-5). The Reliable Change Index (RCI) shows that 73.9% of patients showed improvement on the CAPS-5 and 77.61% on the PCL-5. Additionally, 21.77% (CAPS-5) and 20.0% (PCL-5) showed no change, while 4.84% (CAPS-5) and 2.96% (PCL-5) showed symptom worsening.Discussion: The results show that an intensive outpatient trauma treatment programme, including two evidence-based trauma-focused treatments, exercise, and psychoeducation, is effective for patients suffering from PTSD as a result of multiple traumatization. Subsequent research should focus on more controlled studies comparing the treatment programme with other intensive trauma treatments and less frequent routine treatment.

Intensive outpatient trauma treatment is effective in treating PTSD.Six days of combining prolonged exposure, EMDR, exercise and psycho-education seems feasible and effective in treating PTSD.73.9% of the patients show improvement on the CAPS-5 and 77.61% show improvement on the PCL-5, symptom worsening was there in 4,84, respectively 2.96%.

12-month follow-up of intensive outpatient treatment for PTSD combining prolonged exposure therapy, EMDR and physical activity.

BACKGROUND: Preliminary evidence shows promising treatment outcomes at short-term follow-up for intensive posttraumatic stress disorder (PTSD) treatment, but long-term follow-up studies are sparse. This study is a sequel to a previous pilot study and open trial, set out to investigate treatment outcomes at 12-month follow-up for outpatients completing an 8-day intensive treatment for PTSD. METHODS: All patients were diagnosed with PTSD and had multiple previous psychotherapy attempts (M = 3.1). Patients were assessed at pre-treatment, post-treatment, 3- and 12-month follow-up. Of 35 treated patients, 32 (91.4%) attended the long-term follow-up assessment. The treatment programme combined prolonged exposure therapy, eye movement desensitization and reprocessing, and physical activity. RESULTS: The effect sizes indicated large reductions in symptoms of PTSD, depression, anxiety, interpersonal problems, and well-being. Changes in functioning showed a small-medium effect. Results were stable across the follow-up period. The treatment response rates showed that 46-60% of patients achieved recovery with respect to PTSD symptoms, and that 44-48% no longer met diagnostic criteria for PTSD. CONCLUSIONS: Time-limited and concentrated outpatient treatment for PTSD can yield large and enduring positive outcomes. Controlled trials are needed to establish relative efficacy. TRIAL REGISTRATION: The study was registered in Current Research Information System In Norway (Cristin). Cristin-project-ID: 654,790. Date of registration: 18.03.2019.

Effect of exposure-based vs traditional cognitive behavior therapy for fibromyalgia: a two-site single-blind randomized controlled trial.

ABSTRACT: Fibromyalgia is a debilitating pain condition for which treatment effects are typically modest. The most evaluated psychological treatment is traditional cognitive behavior therapy (T-CBT), but promising effects have recently been seen in exposure-based cognitive behavior therapy (Exp-CBT). We investigated whether Exp-CBT was superior to T-CBT in a randomized controlled trial. Self-referred participants with fibromyalgia (N = 274) were randomized (1:1) to 10 weeks of Exp-CBT or T-CBT. Treatments were delivered online and presented as "CBT for fibromyalgia." Participants were assessed at baseline, weekly during treatment, posttreatment, and at 6- and 12-month follow-up. Primary outcome was the difference in reduction in fibromyalgia severity as measured using the Fibromyalgia Impact Questionnaire (FIQ) over 11 assessment points from baseline to posttreatment, modelled within an intention-to-treat framework using linear mixed effects models fitted on multiple imputed data. Approximately 91% of weekly FIQ scores were collected over the main phase. There was no significant difference between Exp-CBT and T-CBT in the mean reduction of fibromyalgia severity from pretreatment to posttreatment (b = 1.3, 95% CI -3.0 to 5.7, P = 0.544, d = -0.10). Minimal clinically important improvement was seen 60% in Exp-CBT vs 59% in T-CBT. Effects were sustained up to 12 months posttreatment. This well-powered randomized trial indicated that Exp-CBT was not superior to T-CBT for fibromyalgia. Both treatments were associated with a marked reduction in fibromyalgia severity, and the online treatment format might be of high clinical utility. T-CBT can still be regarded a reference standard treatment that remains clinically relevant when compared to novel treatment approaches.

Acceptance and Mindfulness-Based Exposure Therapy for PTSD After Cardiac Arrest: An Open Feasibility Trial.

Background: Posttraumatic stress disorder (PTSD) is prevalent after surviving sudden cardiac arrest (SCA). SCA-induced PTSD is associated with increased mortality and cardiovascular risk, yet no psychotherapeutic treatment has been developed and tested for this population. Exposure therapy is standard treatment for PTSD, but its safety and efficacy remain unconfirmed for SCA survivors: current protocols do not address their specific disease course and have high attrition. Mindfulness-based interventions are typically well-tolerated and have shown promise in reducing PTSD symptoms from other traumas.Objective: This study sought to determine feasibility, safety, and preliminary efficacy of acceptance and mindfulness-based exposure therapy (AMBET), a novel SCA-specific psychotherapy protocol combining mindfulness and exposure-based interventions with cardiac focused psychoeducation to reduce symptoms and improve health behaviors in patients with post-SCA PTSD.Methods: We conducted an open feasibility pilot study from January 2021 to April 2022 with a small sample (N = 11) of SCA survivors meeting DSM-5 PTSD criteria. AMBET comprised eight 90-minute remotely delivered individual sessions. Clinical evaluators assessed PTSD symptoms using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) at baseline, midpoint, posttreatment, and 3-month follow-up.Results: Ten (91%) of 11 enrolled patients completed treatment. Satisfaction was high and patients reported no adverse events. PTSD symptoms significantly improved statistically (P < .001) and clinically with large effect sizes (g = 1.34-2.21) and treatment gains sustained at 3-month follow-up. Posttreatment, 80% of completers (n = 8) showed significant treatment response, 70% (n = 7) with PTSD diagnostic remission. No patient reported symptom increases.Conclusions: This initial trial found AMBET feasible, safe, and potentially efficacious in reducing PTSD following SCA. These encouraging pilot results warrant further research.Trial Registration: ClinicalTrials.gov identifier: NCT04596891.

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.

Eye movement desensitization and reprocessing (EMDR) therapy or supportive counseling prior to exposure therapy in patients with panic disorder: study protocol for a multicenter randomized controlled trial (IMPROVE).

BACKGROUND: Exposure-based therapy is the treatment of choice for anxiety disorders, but many patients do not benefit sufficiently from it. Distressing images of threat related to the future or past may maintain the anxiety symptomatology or impede exposure therapy. An intervention that targets threat-related imagery is eye movement desensitization and reprocessing (EMDR) therapy. The main goal of this multicenter randomized controlled trial is to investigate whether EMDR therapy plus exposure therapy, relative to supportive counseling plus exposure therapy, improves treatment efficacy, tolerability, and adherence in patients with panic disorder. In addition, we will examine potential predictors of optimal treatment allocation, mechanisms of change as well as the long term effects of treatment. Finally, we will assess cost-effectiveness. METHODS: A multicenter randomized controlled trial mixed design will be conducted. Participants will be 50 patients, aged ≥ 18, diagnosed with a panic disorder. They will be randomly assigned to one of two conditions: EMDR therapy (i.e., flashforward strategy) or supportive counseling (each consisting of four weekly sessions of 90 min each) prior to exposure therapy (consisting of eight weekly sessions of 90 min each). Assessments will be made pre-treatment (T1), between-treatments (T2), post-treatment (T3), one month post-treatment (FU1) and six months post-treatment (FU2) by an assessor blind to treatment condition. The primary outcome measure is severity of panic-related symptoms. Secondary outcome measures are: tolerability of exposure therapy (initial avoidance, willingness to start exposure therapy, considered drop-out; no-show and drop-out), related symptomatology (generalized anxiety, depression), and functional impairment. DISCUSSION: The primary goals of this research are to compare the efficacy, tolerability, and adherence of EMDR therapy plus exposure therapy and supportive counseling plus exposure therapy and to identify predictors, moderators, and mediators for treatment success. This multi-center research aims to make a significant contribution to our understanding as to how treatment for patients with anxiety disorders can be optimized, and elucidate who can benefit most from this novel approach.

Changes in avoidance and distress related to trauma reminders in PTSD psychotherapy.

BACKGROUND AND OBJECTIVES: Research has examined reductions in patient distress recounting trauma narratives in Prolonged Exposure (PE) for posttraumatic stress disorder (PTSD). It remains unclear whether changes in distress and avoidance related to environmental trauma reminders matter in PE and other PTSD treatments, including non-exposure Interpersonal Psychotherapy (IPT). METHODS: Data came from adults with chronic PTSD (N = 92) who completed a treatment trial comparing PE, IPT, and Relaxation Therapy (RT). We employed the Self-Initiated In-Vivo Exposure Scale (SIIVES), which measures patient distress from and avoidance of situational trauma reminders, to calculate reliable change in distress and avoidance. PTSD symptoms, depression, quality of life, and functioning assessments were collected before and after 14 weeks of treatment. RESULTS: Overall, 48.1% of patients experienced reliable change in avoidance, while 51.9% showed reliable change in distress. Rates of reliable change did not differ by treatment group, although PE appeared to achieve reliable change earlier. Only one baseline characteristic predicted reliable change: patients with comorbid depression were less likely to reliably change in avoidance. At post-treatment, patients achieving reliable change had lower PTSD severity and depression and increased quality of life and social functioning. Statistical modeling revealed that changes in distress and avoidance related to subsequent reduction in PTSD symptoms in all three treatment groups, though this relationship appeared strongest in PE. LIMITATIONS: The sample was relatively small. CONCLUSIONS: Change in avoidance and distress associated with situational trauma reminders was associated with a range of clinical outcomes and may represent important factors in multiple PTSD psychotherapies.

Intensive outpatient treatment for PTSD: an open trial combining prolonged exposure therapy, EMDR, and physical activity.

Background: Intensive outpatient treatment could be a promising option for patients with post-traumatic stress disorder (PTSD). Objective: The aim of the study was to test the effectiveness of an eight-day (two-week) intensive treatment for PTSD within a public health care setting (open trial design). Method: Eighty-nine patients were offered the choice between intensive treatment and spaced individual treatment, of which 34 (38.2%) chose the intensive format. Patients were assessed with self-report batteries and interviews at pre-treatment, start of treatment, post-treatment and three-month follow-up. Each day consisted of individual Prolonged Exposure therapy, Eye Movement Desensitization and Reprocessing therapy, group psychoeducation, and physical activity. Therapists rotated between patients. Results: Between 55 and 62% of the patients showed a clinically significant change (recovery) in symptoms of PTSD, and the effect sizes were large (d = 1.38-1.52). Patients also showed reduction in symptoms of depression and anxiety, along with improved well-being and interpersonal functioning. Changes in social and work functioning were more ambiguous. There were no dropouts, attendance was high, and patients were highly satisfied with the treatment. Conclusions: The intensive programme was an attractive and effective treatment option for patients with PTSD.

Antecedentes: El tratamiento ambulatorio intensivo podría ser una opción prometedora para los pacientes con trastorno de estrés postraumático (TEPT).Objetivo: El objetivo del estudio fue probar la efectividad de un tratamiento intensivo de 8 días (2 semanas) para el TEPT dentro de un entorno de atención de salud pública (diseño de ensayo abierto).Método: Se ofreció a 89 pacientes elegir entre tratamiento intensivo y tratamiento individual espaciado, de los cuales 34 (38,2%) eligieron el formato intensivo. Los pacientes fueron evaluados con baterías de autoinforme y entrevistas antes del tratamiento, al inicio del tratamiento, después del tratamiento y a los 3 meses de seguimiento. Cada día consistió en terapia de exposición prolongada individual, terapia de reprocesamiento y desensibilización por movimientos oculares, psicoeducación grupal y actividad física. Los terapeutas rotaron entre los pacientes.Resultados: Entre el 55-62% de los pacientes mostraron un cambio clínicamente significativo (recuperación) en los síntomas del TEPT, y los tamaños del efecto fueron grandes (d = 1,38­1,52). Los pacientes también mostraron una reducción en los síntomas de depresión y ansiedad, junto con mejoría en bienestar y funcionamiento interpersonal. Los cambios en el funcionamiento social y laboral fueron más ambiguos. No hubo abandonos, la asistencia fue alta y los pacientes estaban altamente satisfechos con el tratamiento.Conclusiones: El programa intensivo fue una opción de tratamiento atractiva y efectiva para pacientes con TEPT.

Trauma-focused treatments for refugee children: study protocol for a randomized controlled trial of the effectiveness of KIDNET versus EMDR therapy versus a waitlist control group (KIEM).

BACKGROUND: Prevalence of posttraumatic stress disorder (PTSD) in refugees is reportedly higher in comparison to the general population. Refugee children specifically are often coping with trauma and loss and are at risk for mental health difficulties. With staggering numbers of people seeking refuge around the world and 50% being 18 years or younger, research examining the effects of trauma-focused therapies for refugee children with PTSD is highly needed. Both Eye Movement Desensitization and Reprocessing (EMDR) therapy and the child version of Narrative Exposure Therapy (KIDNET) have been used for refugees, although these treatment methods have not been systematically compared. The aim of the current study is to investigate the effectiveness of EMDR and KIDNET, compared to a waitlist control group and with each other, offered to refugee children. METHODS: A randomized controlled three-arm trial has been designed. The primary outcome is PTSD diagnosis and symptom severity assessed with the Clinician-Administered PTSD Scale for Children DSM5 (CAPS-CA-5) at baseline (T1), 1 month post-treatment, or after 8 weeks of waiting (T2) and 3 months follow-up (T3). Additionally, instruments to assess posttraumatic stress symptoms, behavioral and emotional problems, and quality of life perception in children aged 8-18 are conducted at T1, T2, and T3. DISCUSSION: This is the first RCT that examines the effectiveness of EMDR and KIDNET in refugee children aged 8-18 years specifically, compared to a waitlist control group intended to reduce PTSD diagnosis and severity of posttraumatic stress symptoms and comorbid complaints in a growing and challenging population.

A randomized clinical trial of prolonged exposure and applied relaxation for the treatment of Latinos with posttraumatic stress disorder.

Robust evidence supports the use of prolonged exposure therapy (PE) as a first-line treatment for posttraumatic stress disorder (PTSD). However, Latinos have not benefitted equally from advancements in the treatment of PTSD and continue to face barriers to receiving care. There is consensus that it is necessary to support the expansion of high-quality culturally and linguistically appropriate treatment to address disparities experienced by racial and ethnic minorities in behavioral health care. The current study was a randomized controlled trial comparing a culturally adapted PE intervention with applied relaxation (AR) among Spanish-speaking Latinos with PTSD in Puerto Rico. Eligible participants (N = 98) were randomly assigned to PE (n = 49) or AR (n = 49). Both treatments included 12-15 weekly sessions each lasting 60-90 min. The primary outcome, clinician-rated PTSD symptom severity, was assessed using the Clinician-Administered PTSD Scale for DSM-5 at baseline, posttreatment, and 3-month follow-up. Secondary outcomes were assessed using the Patient Health Questionnaire and State-Trait Anxiety Inventory. Results showed a large within-group effect of treatment on PTSD symptoms, PE: d = 1.29, 95% CI [1.12, 2.05]; AR: d = 1.38, 95% CI [1.21, 2.19]. The between-group effect on PTSD symptoms was small, d = -0.09, 95% CI [-0.48, 0.31]. Participants in both treatment conditions reported significant decreases in PTSD symptoms from baseline to follow-up; additionally, significant within-group reductions in depression and anxiety symptoms were observed. These findings underscore the potential benefit of PE and AR for the treatment of Spanish-speaking Latinos with PTSD.

Mindful Emotion Awareness Facilitates Engagement with Exposure Therapy: An Idiographic Exploration Using Single Case Experimental Design.

Exposure therapy works through inhibitory learning, whereby patients are exposed to stimuli that elicit anxiety in order to establish safety associations. Mindful emotion awareness, or nonjudgmental and present-focused attention toward emotions, may facilitate engagement in exposures, which may in turn enhance therapeutic outcome. This study utilizes a single-case experimental design (n = 6) to investigate the effect of mindful emotion awareness training on the use of avoidant strategies during exposures, distress during exposures, overall mindfulness, experiential avoidance, and symptom reduction in a sample of participants with social anxiety disorder. Data were analyzed using a combination of visual inspection and quantitative effect size metrics commonly applied in single-case experimental designs. To further investigate the relationship between distress and avoidant strategy use, contemporaneous and cross-lagged correlations were run. Results highlight individual differences in responses to mindful emotion awareness training and exposure exercises. Given these individual differences, repeated assessment and monitoring over the course of treatment may help clinicians most effectively identify treatment skills that will be most helpful for individual patients.

Intensive outpatient treatment for PTSD: a pilot feasibility study combining prolonged exposure therapy, EMDR, physical activity, and psychoeducation.

Background: Intensive treatment could be effective for patients with post-traumatic stress disorder (PTSD). Objective: The aim of the study was to test the feasibility of an 8-day (2-week) intensive outpatient treatment for PTSD. Method: Treatment each day consisted of individual Prolonged Exposure (PE), Eye Movement Desensitization and Reprocessing (EMDR), and psychoeducation and physical activity in groups. Patients met different therapists from session to session. Results: Six patients started and completed treatment. Levels of attendance of sessions was high. Patients reported that they were satisfied with the treatment, describing it as emotionally taxing, but meaningful. Therapists also described several positive aspects of the treatment format. There were large reductions in PTSD symptoms. Conclusions: Given these promising, but preliminary findings on the programme's feasibility, future research should investigate this treatment format using larger samples and controlled designs.

Los pacientes se reunían con diferentes terapeutas de una sesión a otra.Resultados: Seis pacientes iniciaron y completaron el tratamiento. El nivel de asistencia a las sesiones fue alto. Los pacientes informaron que estaban satisfechos con el tratamiento, describiéndolo como emocionalmente agotador, pero significativo. Los terapeutas también describieron varios aspectos positivos del formato del tratamiento. Hubo grandes reducciones en los síntomas del TEPT.Conclusiones: Teniendo en cuenta estos resultados prometedores, pero preliminares, sobre la viabilidad del programa, la investigación futura debería investigar este formato de tratamiento utilizando muestras más grandes y diseños controlados.

Effectiveness of an intensive treatment programme combining prolonged exposure and EMDR therapy for adolescents suffering from severe post-traumatic stress disorder.

Background: Following promising effects of an intensive trauma treatment for adults, the question arises whether adolescents who suffer from severe post-traumatic stress disorder (PTSD) can also profit from a similar treatment programme. Objective: To assess the effectiveness of an intensive trauma-focused treatment programme combining two evidence-based trauma-focused therapies and physical activities for adolescents suffering from severe PTSD. Method: Treatment consisted of daily sessions of prolonged exposure (PE) therapy and eye movement desensitization and reprocessing (EMDR) therapy supplemented with physical activity (13 days on average). All patients (N = 27; 96.3% women, mean age = 16.1 years; SD = 1.3) had been exposed to one or more (interpersonal) traumatic events. Twenty-two of them (81.5%) also fulfilled the diagnostic criteria of a comorbid psychiatric disorder (mean number of comorbid disorders = 2.22). The majority of patients were referred because previous treatment was difficult or complications were expected to occur. Severity of PTSD symptoms and presence of a PTSD diagnostic status were assessed using the Dutch version of the CAPS-CA IV at baseline, post-treatment and at 3-month follow-up. Results: CAPS-CA IV scores decreased significantly from pre- to post-treatment (Cohen's d = 1.39). Of all patients 81.5% (n = 22) showed a clinically meaningful response, of whom 63% (n = 17) no longer fulfilled the diagnostic criteria of PTSD at post-treatment as established with the CAPS-CA IV. The results were maintained at 3-month follow-up. During treatment, neither adverse events nor dropout occurred. Conclusions: The results suggest that an intensive trauma-focused treatment programme combining prolonged exposure, EMDR therapy, and physical activity can be an effective and safe treatment for adolescents suffering from severe PTSD and multiple comorbid psychiatric disorders.

Antecedentes: Después de los efectos prometedores de un tratamiento intensivo del trauma para adultos, surge la pregunta de si los adolescentes que padecen un trastorno de estrés postraumático severo (TEPT) también pueden beneficiarse de un programa de tratamiento similar.Objetivo: Evaluar la efectividad de un programa de tratamiento intensivo centrado en el trauma que combina dos terapias centradas en el trauma basadas en la evidencia y actividad física para adolescentes que sufren de TEPT grave.Método: El tratamiento consistió en sesiones diarias de terapia de exposición prolongada (PE) y terapia de desensibilización y reprocesamiento por movimientos oculares (EMDR) complementadas con actividad física (13 días en promedio). Todos los pacientes (N = 27; 96.3% mujeres, edad media = 16,1 años; DE = 1.3) habían estado expuestos a uno o más eventos traumáticos (interpersonales). Veintidós de ellos (81.5%) también cumplían los criterios diagnósticos de un trastorno psiquiátrico comórbido (número medio de trastornos comórbidos = 2.22). La mayoría de los pacientes fueron derivados porque el tratamiento previo fue difícil o se esperaba que ocurrieran complicaciones. La gravedad de los síntomas de TEPT y la presencia del diagnóstico de TEPT se evaluaron utilizando la versión holandesa del CAPS-CA IV al inicio, después del tratamiento y a los 3 meses de seguimiento.Resultados: Los puntajes de CAPS-CA IV disminuyeron significativamente pre a post tratamiento (d de Cohen = 1,39). De todos los pacientes, el 81,5% (n = 22) mostró una respuesta clínicamente significativa, de los cuales el 63% (n = 17) ya no cumplía con los criterios diagnósticos de TEPT en el postratamiento según lo establecido con el CAPS-CA IV. Los resultados se mantuvieron a los 3 meses de seguimiento. Durante el tratamiento, no se produjeron eventos adversos ni abandonos.Conclusiones: Los resultados sugieren que un programa de tratamiento intensivo centrado en el trauma que combine exposición prolongada, terapia EMDR y actividad física puede ser un tratamiento eficaz y seguro para los adolescentes que padecen TEPT severo y múltiples trastornos psiquiátricos comórbidos.

Meta-Analysis of the Treatment of Posttraumatic Stress Disorder in Adults With Comorbid Severe Mental Illness.

Objective: To evaluate the efficacy of psychosocial treatments for posttraumatic stress disorder (PTSD) among individuals with a comorbid severe mental illness (SMI; ie, schizophrenia, bipolar disorder, major depressive disorder).Data Sources: PubMed, PsycINFO, CINAHL, and Cochrane Library were searched from January 1998 to March 2020 using keywords related to PTSD, treatment, and severe mental illness.Study Selection: All clinical trials for PTSD psychotherapy among individuals with SMI were included. From 38 potentially eligible studies, a total of 14 clinical trials across 684 individuals with comorbid SMI and PTSD were identified and included in the analysis.Data Extraction: Data on demographic, SMI diagnosis, symptom severity, sample attrition, and treatment protocol received were extracted. Effect size calculations and subsequent meta-analyses were conducted using the Meta-Analysis Package for R (metafor) version 2.1-0 in R (3.6.0).Results: PTSD treatments had a large effect on PTSD outcomes among individuals with SMI, with patients experiencing a standard deviation reduction in PTSD symptomatology pre- to post-treatment (g = -1.009, P < .001, k = 34). Prolonged exposure (g = -1.464; P < .001; SE = 0.276; k = 5), eye movement desensitization and reprocessing (g = -1.351; P < .001; SE = 0.276; k = 5), and brief treatment program (g = -1.009; P < .001; SE = 0.284; k = 5) had the largest effects on PTSD symptoms.Conclusions: Although underrepresented in the PTSD literature, PTSD psychotherapies are effective for individuals with SMI. Treatments with an exposure-based component may have greater efficacy in this clinical population.

Vagus nerve stimulation promotes extinction generalization across sensory modalities.

Traumatic experiences involve complex sensory information, and individuals with trauma-related psychological disorders, such as posttraumatic stress disorder (PTSD), can exhibit abnormal fear to numerous different stimuli that remind them of the trauma. Vagus nerve stimulation (VNS) enhances extinction of auditory fear conditioning in rat models for PTSD. We recently found that VNS-paired extinction can also promote extinction generalization across different auditory cues. Here we tested whether VNS can enhance extinction of olfactory fear and promote extinction generalization across auditory and olfactory sensory modalities. Male Sprague Dawley rats were implanted with a stimulating cuff on the cervical vagus nerve. Rats then received two days of fear conditioning where olfactory (amyl acetate odor) and auditory (9 kHz tones) stimuli were concomitantly paired with footshock. Twenty-four hours later, rats were given three days of sham or VNS-paired extinction (5 stimulations, 30-sec trains at 0.4 mA) overlapping with presentation of either the olfactory or the auditory stimulus. Two days later, rats were given an extinction retention test where avoidance of the olfactory stimulus or freezing to the auditory stimulus were measured. VNS-paired with exposure to the olfactory stimulus during extinction reduced avoidance of the odor in the retention test. VNS-paired with exposure to the auditory stimulus during extinction also decreased avoidance of the olfactory cue, and VNS paired with exposure to the olfactory stimulus during extinction reduced freezing when the auditory stimulus was presented in the retention test. These results indicate that VNS enhances extinction of olfactory fear and promotes extinction generalization across different sensory modalities. Extinction generalization induced by VNS may therefore improve outcomes of exposure-based therapies.

Efficacy of Meditation-Based Interventions on Post-Traumatic Stress Disorder (PTSD) Among Veterans: A Narrative Review.

BACKGROUND: Decades of research have documented post-traumatic stress disorder (PTSD) symptoms in war veterans. Current treatment options for PTSD are unappealing as they either require re-exposure to the traumatic event or medications that are greatly impacted by comorbidities. Meditation-based interventions are a promising alternative. However, there is a dearth of research examining their impact. PRIMARY OBJECTIVE: The purpose of this study was to examine meditation-based interventions tested for efficacy in treating PTSD among veterans and provide collective evidence. METHODS: Authors searched the MEDLINE and CINAHL databases for relevant studies using the following inclusion criteria: (1) published in peer-reviewed journals; (2) conducted between January 2014 and July 2020; (3) described the evaluation of interventions; and (4) incorporated quantitative or mixed methods. SETTING: United States. PARTICIPANTS: U.S. Veterans. RESULTS: A total of 15 studies (ten articles) met the inclusion criteria. Four tested Transcendental Meditation (n = 4), three tested Mantra Meditation (n = 3), two tested Mindful Meditation (n = 2), one tested Breathing-based Meditation (n = 1), one tested Mindfulness-based Exposure Therapy (n = 1), one tested Cognitively-based Compassion Training Meditation (n = 1), one tested Mantra Meditation and Mindfulness-based Treatment (n = 1), one tested Mindfulness-based PTSD Treatment (n = 1), and one tested Primary Care Brief Mindfulness Program (n = 1). The most common duration was 8 weeks (n = 8) and the most common evaluation design was the randomized controlled trial (n = 10). The most common outcome measure was the Clinician Administered PTSD Scale (CAPS) (n = 12). CONCLUSION: All interventions reported improvements in PTSD symptoms. Based on this review, meditation-based therapy is a promising approach for managing PTSD, particularly among veterans resistant to trauma-focused therapies. Randomized control trials with large sample sizes that apply CAPS as their primary outcome measure, and take into account effect size, attrition rates, and blinding are recommended for further research.

Mindfulness and Interoceptive Exposure Therapy for Anxiety Sensitivity in Atrial Fibrillation: A Pilot Study.

Atrial fibrillation is the most common cardiac arrhythmia and symptoms overlap with physiological sensations of anxiety. Patients with atrial fibrillation can demonstrate anxiety sensitivity even in the absence of actual atrial fibrillation symptoms. Interoceptive exposure is effective in treating anxiety sensitivity, and recently, mindfulness has been proposed as an enhancement strategy to facilitating inhibitory learning in exposure therapy. This pragmatic study piloted a brief mindfulness and interoceptive exposure treatment for anxiety sensitivity in atrial fibrillation. Eight participants with atrial fibrillation and elevated anxiety sensitivity from a hospital cardiology department participated in the treatment. Anxiety sensitivity significantly decreased during the course of the intervention. These initial findings show proof of concept for this brief intervention in a cardiac-specific behavioral medicine setting.

Enhancing extinction with response prevention via imagery-based counterconditioning: Results on conditioned avoidance and distress.

BACKGROUND AND OBJECTIVES: Maladaptive avoidance is a core characteristic of anxiety-related disorders. Its reduction is often promoted using extinction with response prevention (ExRP) procedures, but these effects are often short-lived. Research has shown that pairing a feared stimulus with a stimulus of an incompatible valence (i.e., counterconditioning) may be effective in reducing fear. This laboratory study tested whether positive imagery during ExRP (i.e., imagery counterconditioning protocol) can also reduce avoidance. METHODS: In the counterconditioning procedure, participants imagined a positive sound. There were four phases. First, participants were presented with squares on a computer screen of which one (CS+) was paired with an aversive sound and another (CS-) was not. Second, they learned to avoid the negative sound in the presence of the CS+, via a key press. Third, they were assigned to either the Counterconditioning (that was asked to imagine a positive sound during ExRP) or No Counterconditioning group (standard ExRP). Finally, they performed a test phase that consisted of two parts: in the first part, avoidance responses were available for each CS and in the second part, these responses were prevented. RESULTS: The Counterconditioning intervention resulted in a short-lived reduction of distress associated with the CS+. However, groups did not differ in avoidance or distress during the test phases. LIMITATIONS: US-expectancy ratings were collected only at the end of the experiment. CONCLUSIONS: The results indicate that positive imagery during ExRP may be effective in reducing distress during the intervention. Explanations for the persistence of avoidance and fear are discussed.

A randomized clinical trial to assess the efficacy of trial-based cognitive therapy compared to prolonged exposure for post-traumatic stress disorder: preliminary findings.

BACKGROUND: Post-traumatic stress disorder (PTSD) is a prevalent mental health condition that is often associated with psychiatric comorbidities and changes in quality of life. Prolonged exposure therapy (PE) is considered the gold standard psychological treatment for PTSD, but treatment resistance and relapse rates are high. Trial-based cognitive therapy (TBCT) is an effective treatment for depression and social anxiety disorder, and its structure seems particularly promising for PTSD. Therefore, we evaluated the efficacy of TBCT compared to PE in patients with PTSD. METHODS: Ninety-five patients (77.6% females) who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, criteria for PTSD were randomly assigned to receive either TBCT (n = 44) or PE (n = 51). Patients were evaluated before and after treatment, and at follow-up 3 months after treatment. The primary outcome was improvement in PTSD symptoms as assessed by the Davidson Trauma Scale (DTS). Secondary outcomes were depression, anxiety, and dysfunctional attitudes assessed by the Beck Depression/Anxiety Inventories and Dysfunctional Attitudes Scale, as well as the dropout rate. RESULTS: A significant reduction in DTS scores was observed in both arms, but no significant difference between treatments. Regarding the secondary outcomes, we found significant differences in depressive symptoms in favor of TBCT, and the dropout rate was lower in the TBCT group than the PE group. CONCLUSION: Our preliminary results suggest that TBCT may be an effective alternative for treating PTSD. Further research is needed to better understand its role and the mechanisms of change in the treatment of this disorder.
