Improvement In PTSD Symptoms Research Articles

Using network analysis to characterize clinical improvement during cognitive processing therapy.

Cross-sectional network studies find mixed results regarding changes in network structure as a response to treatment across disorders. This study characterized improvement in mental health following Cognitive Processing Therapy (CPT) for PTSD in veterans from the perspective of network psychometrics and explored how cross-sectional networks inform our understanding of PTSD recovery. Veterans with PTSD participated in CPT-based intensive treatment programs (ITPs), offered in two-week (N=635) or three-week (N=457) formats. PTSD symptoms were self-reported on the PTSD Checklist for DSM-5 (PCL-5) at pre-, mid-, and post-treatment. Cross-sectional networks for each time point were compared using network comparison tests. Linear regression tested if the relationship of initial treatment gains from admission to mid-treatment with overall outcomes was associated with the expected influence centrality of a node. Substantial improvement in PTSD symptoms were found, but network structure remained largely unaffected, with global edge strength increasing from pre-to post-treatment. Initial treatment gains in nodes with high expected influence were associated with overall treatment outcomes. A post-hoc simulation based on a common-cause model produced similar regression results, indicating that while our findings align with spreading activation, they are not exclusive to this mechanism. The indiscernibility of cross-sectional networks between pre- and post-treatment raises questions about whether cross-sectional networks can illuminate PTSD recovery beyond traditional measures of treatment response.

Implementing group therapy for posttraumatic stress disorder within a primary care setting: A pilot study

BackgroundPosttraumatic stress disorder (PTSD) is associated with comorbid psychiatric and medical conditions and high rates of medical service utilization. Given that PTSD is highly prevalent in the primary care setting, group therapy delivered within this setting has the potential to treat large numbers of patients. To date, few studies have examined the feasibility or effectiveness of group therapy for PTSD within primary care. MethodsA pilot study of a PTSD group therapy intervention based on the Trauma Information Group model was conducted in a Federally Qualified Health Center (FQHC). Across 9 cohorts, 32 individuals with PTSD completed 8–10 group therapy sessions. Self-reported PTSD severity was assessed using the PTSD Checklist for DSM-5 (PCL-5) at baseline and post-treatment. ResultsFifty percent of participants had a PTSD treatment response (PCL-5 score reduction ≥10) following group therapy and paired t-tests demonstrated a statistically significant reduction in PCL-5 scores from pre- to post-treatment. Patient demographic characteristics and psychiatric comorbities were not associated with treatment response. LimitationsThe small sample size, demographic characteristics, and FQHC setting potentially limit the generalizability of these findings. Treatment dropout rates and associated factors also were not examined. ConclusionsThe Trauma Information Group treatment for PTSD was feasible to implement within a low resourced primary care setting and led to improvement in PTSD symptoms in this pilot study. These findings suggest that offering group therapy for PTSD within primary care could improve access to effective treatment and warrant future research to examine feasibility and effectiveness in this setting.

Immediate Effects of Mindful Awareness in Body-Oriented Therapy as an Adjunct to Medication for Opioid Use Disorder

The need for improve medication for opioid use disorder (MOUD) treatment outcomes can be limited by co-occurring polysubstance use, mental health, and chronic pain conditions. Interoceptive training may facilitate well-being and support medication treatment for MOUD.ObjectivesWhile effective, medication for opioid use disorder (MOUD) treatment outcomes can be limited by co-occurring polysubstance use, mental health, and chronic pain conditions. Interoceptive training may facilitate well-being and support medication treatment for MOUD. This study examined the pre-post effects of the mindfulness-based intervention Mindful Awareness in Body-oriented Therapy (MABT) as an adjunct to MOUD. MABT teaches interoceptive awareness skills to promote self-care and emotion regulation.MethodParticipants stabilized on medication for opioid use disorder (OUD) (n = 303) from six community clinics in Northwestern United States were recruited and randomly assigned to MABT plus MOUD or MOUD only. In a mixed-methods study, we used an intent-to-treat approach (analyzing participants based on their assigned group, regardless of adherence) to examine the proportion of days abstinent from non-prescribed opioids, and other substance use (primary outcomes) at baseline and 3 months post-intervention. Secondary outcomes included symptoms of mental health distress, emotional regulation difficulties, pain and physical symptom indicators, interoceptive awareness, and mindfulness skills. Participant experience of MABT was collected through post-intervention surveys. Changes in outcomes were assessed using linear mixed models; content analysis was used to analyze the qualitative data.ResultsLevels of overall substance use were low and did not differ between groups. Significant improvements in PTSD symptoms, interoceptive awareness, pain severity, pain activity interference, and physical symptom frequency were found for those who received MABT compared to MOUD only.ConclusionsIn this stable MOUD population, substance use outcomes were not improved; however, MABT demonstrated significant positive changes across multiple health outcomes critical for improving MOUD treatment.PreregistrationClinicalTrials.gov identifer: NCT04082637.

A hospital and community-based violence intervention program for Black & Latino youth and their caregivers.

Black and Latino youth are disproportionately affected by trauma from community violence, but to date, few data support the benefit of evidence-based treatments for these youth or of including peer support to engage these youth in mental health services. From 2018 until 2020, a hospital and community-based violence intervention program in Philadelphia pilot tested the integration of home and community-based Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) with peer services and case management for youth impacted by community violence. This study describes the implementation of this intervention. Data was gathered by querying the program's database. The Child Post Traumatic Stress Symptom Severity Scale (CPSS-SR-5) and the Short Mood and Feelings Questionnaire (SMFQ) were utilized to evaluate the participants' pre- and post-intervention assessment of PTSD and depression. The sample (N = 50) consisted of Black and Latino youth, mean age 14. Twenty-nine (58%) completed TF-CBT, and 82% met peer and case management goals. Youth who completed therapy showed significant improvement in both PTSD and depression symptoms at post-test. To our knowledge, this is the first study describing the implementation of home and community-based TF-CBT with peer support and case management. The study's limitations and need for further research are discussed.

Distress variability during exposure therapy and its relationship with PTSD symptom decline

Background and objectivesInhibitory Learning Theory (ILT) framework implies that in-session distress variability may promote extinction learning and thereby enhance exposure therapy efficacy. Thus far, research has mainly focused on in-session distress reduction. The aim of the current study was to assess whether in-session distress variability predicts next session PTSD symptom decline in PTSD patients receiving prolonged exposure (PE). MethodsEighty-six patients with PTSD received 14 to 16 sessions of PE. Using dynamic panel models, we assessed the temporal relation (i.e., within-persons) between in-session distress variability and PTSD symptom decline. Moreover, we assessed the averaged relation (i.e., between-persons) between in-session distress variability and PTSD symptom decline. ResultsTemporal analyses showed that in-session distress variability did not precede PTSD symptom improvement. Averaged analyses showed that distress variability was related to PTSD symptom improvement. LimitationThe operationalization of distress variability appeared to deviate from its theoretical conceptualization. ConclusionsIn absence of distress reduction, distress variability can vary. However, our findings suggest that in-session distress variability does not drive symptom reduction during PE. In contrast, averaged over participants, distress variability was related to symptom improvement, suggesting that those with a more variable distress pattern across sessions show better treatment response. More empirical work is needed to shed light on the effect of distress variability during exposure sessions on treatment outcome and to offer grounds for clinical recommendations.

Immediate Effects of Mindful Awareness in Body-oriented Therapy as an Adjunct to Medication for Opioid Use Disorder.

While effective, medication for opioid use disorder (MOUD) treatment outcomes can be limited by co-occurring polysubstance use, mental health and chronic pain conditions. Interoceptive training may facilitate well-being and support medication treatment for MOUD. This study examined the pre-post effects of the mindfulness-based intervention Mindful Awareness in Body-oriented Therapy (MABT) as an adjunct to MOUD. MABT teaches interoceptive awareness skills to promote self-care and emotion regulation. People stabilized on medication for OUD (N = 303) from 6 community clinics in Northwestern United States were recruited and randomly assigned to MABT plus MOUD or MOUD only. In a mixed-methods study, we used an intent-to-treat approach to examine the proportion of days abstinent from non-prescribed opioids, and other substance use (primary outcomes) at baseline and 3 months post-intervention. Secondary outcomes included symptoms of mental health distress; emotional regulation difficulties; pain and physical symptom indicators; interoceptive awareness and mindfulness skills. Participant experience of MABT was collected through post-intervention surveys. Changes in outcomes were assessed using linear mixed models; content analysis was used to analyze the qualitative data. Levels of overall substance use were low and did not differ between groups. Significant improvements in PTSD symptoms, interoceptive awareness, pain severity, pain activity interference, and physical symptom frequency were found for those who received MABT compared to MOUD only. In this stable MOUD population, substance use outcomes were not improved, however MABT demonstrated significant positive changes across multiple health outcomes critical for improving MOUD treatment.

AIP-based Professional Intervention Program for Adversity for trauma and stress reduction in groups: a pilot study in Ethiopia.

Drawing from the principles of EMDR (Eye Movement Desensitization and Reprocessing) therapy and the AIP model, the Professional Intervention Program for Adversity (PIPA) was developed with the objective of amalgamating low-intensity group exercises into a unified framework, as a comprehensive intervention for group therapy. The PIPA Program integrates various aspects of EMDR therapy-such as stabilization, resourcing, desensitization, reprocessing, and forming beliefs about the self and future-into a cohesive program. The program's structure includes self-regulation exercises, the Pillars of Life, the Flash Technique, and the Quadrants exercise. The PIPA Program was administered to more than 220 individuals with a high probability of traumatization by the two-year civil war in Ethiopia (2020-2022). The results of this study show a statistically significant improvement in PTSD symptoms on PCL-5 scores (from M = 38.58 to M = 20.59) after completing the entire PIPA Program and statistically significant lower SUDS scores within the program segments of the Flash Technique and the Quadrants exercises. Future studies should explore the long-term effects of the PIPA Program and its broader application across different therapeutic contexts. The findings suggest that the PIPA Program is a promising group-based intervention for trauma treatment that is safe and effective, especially in non-clinical settings and for culturally diverse populations.

A scoping review of the Trauma Recovery Center model for underserved victims of violent crime.

Victimization in the United States is common and has long lasting negative impacts for individuals, often disproportionately impacting those of color and from low socioeconomic communities. The Trauma Recovery Center (TRC) model aims to provide comprehensive mental health and wrap-around case management services for underserved victims of crime. Following PRISMA-ScR guidelines, we sought to further our knowledge about the impact of the TRC model. Twelve studies met the inclusion criteria. Studies were based at three sites. Access to treatment ranged from 55.7% to 72.3%; treatment completion rates ranged from 40.4% to 43.0%. Individuals who completed mental health services showed improvement in PTSD, anxiety, and depression symptoms, while experiencing lower rates of injury recidivism. Several studies demonstrated improvement in mental health symptoms and social needs in individuals from underserved communities. Researchers should focus on expanding and diversifying upon current knowledge to better understand the impact of the TRC model.

Pilot randomized controlled trial of biofeedback on reducing psychological and physiological stress among persons experiencing homelessness.

People experiencing homelessness report increased exposure to traumatic life events and higher rates of depression, anxiety, and post-traumatic stress disorder as compared with the general population. Heart rate variability-biofeedback (HRV-BF) has been shown to decrease symptoms of stress, anxiety, depression, and PTSD. However, HRV-BF has not been tested with the most vulnerable of populations, homeless adults. The purpose of this randomized controlled trial was to compare the effectiveness of an HRV-BF intervention versus a Health Promotion (HP) active control intervention focused on improving mental health symptoms among homeless adults. Guided by a community advisory board, homeless adults residing in Skid Row, Los Angeles (n=40) were randomized to either the HRV-BF or an active HP control group and received eight weekly, 30-min sessions over two months, delivered by a nurse-led community health worker team. Dependent variables of HRV, mental health, anxiety, depression, and PTSD were measured at baseline, the 8-week session, and/or 2-month follow-up. All intervention sessions were completed by 90% (36/40) of participants. Both the HRV-BF and HP interventions showed significant increases in HRV from baseline to 2-month follow-up, with no significant difference between the intervention groups. The HRV-BF programme revealed a somewhat greater, although non-significant, improvement in anxiety, depression, and PTSD symptoms than the HP programme. The usefulness of both interventions, focused on emotional and physical health, warrants future studies to examine the value of a combined HRV-BF and HP intervention.

Treating a common comorbidity: Pain outcomes following a 3-week cognitive processing therapy-based intensive treatment for posttraumatic stress disorder address.

Posttraumatic stress disorder (PTSD) commonly co-occurs with pain and has been implicated in the maintenance of chronic pain. However, limited research has examined whether intervening for PTSD can hinder or optimize treatment outcomes for co-occurring pain and PTSD. In the present study, we examined changes in pain, PTSD, and depressive symptoms among 125 veterans completing a 3-week cognitive processing therapy (CPT)-based intensive treatment program (ITP) for PTSD. We also explored whether pretreatment pain interference predicted changes in PTSD and depressive symptom severity and whether larger changes in pain interference over the course of treatment were associated with larger changes in PTSD and depressive symptom severity. Linear mixed models revealed that participants' pain interference decreased throughout treatment, d = 0.15, p = .039. Higher levels of pretreatment pain interference were associated with higher PTSD, p = .001, and depressive symptom severity, p = .014, over time. Larger reductions in pain interference corresponded to more improvement in PTSD symptoms, β = -.03; p < .001, but not depressive symptoms. These findings indicate that ITPs for PTSD can reduce pain interferences, albeit to a small degree, and that reductions in pain interference can contribute to reductions in PTSD symptom severity. Future studies should examine which treatment components contribute to larger changes in symptom severity for veterans with co-occurring pain and PTSD.

Neuropsychological Correlates ofPTSD andDepressive Symptom Improvement inCompensatory Cognitive Training forVeterans With a History ofMild Traumatic Brain Injury.

Mild traumatic brain injury (mTBI), depression, and PTSD are highly prevalent in post-9/11 veterans. With the comorbidity of depression and PTSD in post-9/11 veterans with mTBI histories and their role in exacerbating cognitive and emotional dysfunction, interventions addressing cognitive and psychiatric functioning are critical. Compensatory Cognitive Training (CCT) is associated with improvements in prospective memory, attention, and executive functioning and has also yielded small-to-medium treatment effects on PTSD and depressive symptom severity. We sought to examine neuropsychological correlates of PTSD and depressive symptom improvement in veterans with a history of mTBI who received CCT. Thirty-seven post-9/11 veterans with mTBI histories and cognitive complaints received 10 weekly 120-minute CCT group sessions. Participants completed a baseline neuropsychological assessment, including tests of premorbid functioning, attention/working memory, processing speed, verbal learning/memory, and executive functioning, and completed psychiatric symptom measures (PTSD and depression) at baseline, post-treatment, and a 5-week follow-up. Paired samples t-tests were used to examine statistically significant changes in PTSD (total and symptom cluster scores) and depressive symptom scores over time. Pearson's correlations were calculated between neuropsychological scores and PTSD and depressive symptom change scores at post-treatment and follow-up. Neuropsychological measures identified as significantly correlated with psychiatric symptom change scores were entered as independent variables in multivariable regression analyses to examine their association with symptom change at post-treatment and follow-up. Over 50% of CCT participants had clinically meaningful improvement in depressive symptoms (≥17.5% score reduction), and over 20% had clinically meaningful improvement in PTSD symptoms (≥10-point improvement) at post-treatment and follow-up. Examination of PTSD symptom cluster scores revealed a statistically significant improvement in avoidance/numbing at follow-up. Bivariate correlations indicated that worse baseline performance on Category Fluency was moderately associated with PTSD symptom improvement at post-treatment. Worse performance on both Category Fluency and Category Switching Accuracy was associated with improvement in depressive symptoms at post-treatment and follow-up. Worse performance on Trail-Making Number-Letter Switching was also associated with improvement in depressive symptoms at follow-up. Subsequent regression analyses revealed that worse processing speed and worse aspects of executive functioning at baseline were associated with depressive symptom improvement at post-treatment and follow-up. Worse baseline performances on tests of processing speed and aspects of executive functioning were significantly associated with improvements in PTSD and depressive symptoms during the trial. Our results suggest that cognitive training may bolster skills that are helpful for PTSD and depressive symptom reduction and that those with worse baseline functioning may benefit more from treatment because they have more room to improve.

Multi-Site Randomized Trial of Inpatient Palliative Care for Hospitalized Patients Undergoing Hematopoietic Stem Cell Transplantation

Background: Patients with hematologic malignancies experience a substantial decline in their quality of life (QOL) and psychological health during their hospitalization for hematopoietic stem cell transplantation (HSCT). Early single center studies established the feasibility and promising preliminary efficacy of integrating palliative care during the HSCT hospitalization. However, data to test the efficacy of this care model across diverse care settings are lacking. Methods: We conducted a multi-site randomized trial among 360 adults with hematologic malignancies undergoing autologous or allogeneic HSCT at three academic institutions. Patients were randomly assigned to an inpatient palliative care intervention (n= 180) versus usual care (n=180), stratified by study site and type of HSCT. Intervention participants met with a palliative care clinician at least twice weekly during the HSCT hospitalization to address their physical and psychological symptoms. Patients assigned to usual care received all supportive care measures provided by the HSCT team and could be seen by palliative care upon request. We assessed patient QOL (Functional Assessment of Cancer Therapy (FACT) - Bone Marrow Transplant), depression and anxiety symptoms (Hospital Anxiety and Depression Scale), post-traumatic stress (PTSD) symptoms (PTSD Checklist), symptom burden (Edmonton Symptom Assessment Scale-Revised), and fatigue (FACT-Fatigue, higher scores indicate lower fatigue) at baseline and week-2 during hospitalization. The primary endpoint was QOL at week-2 during the HSCT hospitalization when patients typically experience their QOL nadir during HSCT. We used analysis of covariance, adjusting for baseline scores, to evaluate the effect of the intervention on patient-reported outcomes at week-2. Results: We enrolled 69.5% (360/518) of eligible patients (mean age = 55.4 (SD=12.5), 61.9% male, 76.6% White, 23.4% racial minorities, 8.7% Hispanic ethnicity, and 50.2% underwent allogeneic HSCT) between October 2018 and July 2022. Compared to those receiving usual care, participants receiving the inpatient palliative care intervention reported better QOL (95.5 vs. 89.3, P&amp;lt;0.001), and lower depression (5.9 vs. 6.9, P=0.041) and PTSD symptoms (26.0 vs. 28.2, P = 0.022) at week-2. Intervention participants also reported lower symptom burden (35.3 vs. 40.1, P=0.018) and better fatigue scores (28.6 vs. 25.6, p=0.014) compared to those assigned to usual care at week-2 during HSCT hospitalization. Anxiety symptoms (HADS-A) did not demonstrate a measurable difference between the two groups at week-2 during HSCT. Conclusions: In this multi-site randomized clinical trial, inpatient palliative care led to substantial improvements in patients' QOL, depression and PTSD symptoms, symptom burden, and fatigue during HSCT hospitalization compared to usual care. Integrated palliative care should be considered a new standard of care for patients hospitalized for HSCT.

The role of posttraumatic guilt and anger in integrated treatment for PTSD and co-occurring substance use disorders among primarily male veterans.

PTSD and substance use disorders (SUD) frequently co-occur among veterans. Integrated exposure-based treatments, such as Concurrent Treatment of PTSD and SUD Using Prolonged Exposure (COPE), are efficacious in reducing PTSD and SUD symptoms and posttraumatic emotions. This study examines whether guilt and anger (a) decreased in a randomized clinical trial comparing COPE with Relapse Prevention (RP) therapy for SUD and (b) mediated PTSD and SUD symptom reductions or vice versa. Veterans (90.1% men) diagnosed with PTSD and SUD were randomized to 12 sessions of COPE (n = 54) or RP (n = 27). Guilt and anger were assessed at 10 time points during treatment. Multilevel linear models assessed changes in guilt and anger across treatments and lagged multilevel mediation analyses assessed within-subject change in guilt and anger predicting PTSD and percent days of substance use, and vice versa. Guilt (B = -.12, SE = .02, p < .001) and anger (B = -.13, SE = .02, p < .001) improved in both treatments, however guilt was significantly lower in Sessions 7 through 11 among veterans receiving COPE. Improvement in guilt mediated PTSD symptom improvement in both treatment groups (B = -.08, SE = .04, 95% CI [-.16, -.01]), and PTSD symptom improvement mediated anger reduction in COPE (B = -.03, SE = .01, 95% CI [-.06, -.01]). The substance use models were insignificant. Among veterans, integrated, trauma-focused treatments may be associated with greater guilt (directly) and anger (indirectly) reductions due to processing trauma.

Comparing phase-based treatment, prolonged exposure, and skills-training for Complex Posttraumatic Stress Disorder: A randomized controlled trial

ObjectiveThis study examines treatment effects in STAIR Narrative Therapy (SNT), a phase-based treatment where Skills Training in Affective and Interpersonal Regulation (STAIR) precedes Narrative Therapy (NT), compared to Prolonged Exposure (PE) and to STAIR. MethodNinety-two adult patients diagnosed with DSM-5 PTSD and ICD-11 CPTSD following childhood abuse were randomly assigned to enhanced versions of SNT (12 group STAIR sessions + 8 individual NT sessions), PE (8–16 individual sessions), or STAIR (12 group STAIR sessions) provided in residential care. Outcome was assessed by mixed models. ResultsPE produced greater improvements in DSM-5 PTSD symptoms compared to SNT from pre-treatment to post-treatment, but not compared to STAIR. Reductions in ICD-11 CPTSD symptoms were not significantly different among conditions. From pre-treatment to 1 year follow-up, PE produced greater PTSD symptom improvements than SNT and STAIR, and PE and STAIR produced greater CPTSD symptom improvements than SNT. ConclusionsThe predicted stronger effect of SNT compared to PE and STAIR on DSM-5 PTSD and ICD-11 CPTSD symptoms was not supported by the findings. The benefits of immediate trauma-focused treatments (TFT) as compared to phase-based treatments, and the potential non-inferiority of skills-training as compared to TFT in CPTSD needs to be further investigated.

Using machine learning to predict sudden gains in intensive treatment for PTSD

Sudden gains have been found in PTSD treatment across samples and treatment modality. Sudden gains have consistently predicted better treatment response, illustrating clear clinical implications, though attempts to identify predictors of sudden gains have produced inconsistent findings. To date, sudden gains have not been examined in intensive PTSD treatment programs (ITPs). This study explored the occurrence of sudden gains in a 3-week and 2-week ITP (n = 465 and n = 235), evaluated the effect of sudden gains on post-treatment and follow-up PTSD severity while controlling for overall change, and used three machine learning algorithms to assess our ability to predict sudden gains. We found 31% and 19% of our respective samples experienced a sudden gain during the ITP. In both ITPs, sudden gain status predicted greater PTSD symptom improvement at post-treatment (t2 W=−8.57, t3 W=−14.86, p < .001) and at 3-month follow-up (t2 W=−3.82, t3 W=−5.32, p < .001). However, the effect for follow-up was no longer significant after controlling for total symptom reduction across the ITP (t2 W=−1.59, t3 W=−0.32, p > .05). Our ability to predict sudden gains was poor (AUC <.7) across all three machine learning algorithms. These findings demonstrate that sudden gains can be detected in intensive treatment for PTSD, though their implications for treatment outcomes may be limited. Moreover, despite the use of three machine-learning methods across two fairly large clinical samples, we were still unable to identify variables that accurately predict whether an individual will experience a sudden gain during treatment. Implications for clinical application of these findings and for future studies are discussed.

Open-label study of consecutive ibogaine and 5-MeO-DMT assisted-therapy for trauma-exposed male Special Operations Forces Veterans: prospective data from a clinical program in Mexico

ABSTRACT Background: Research in psychedelic medicine has focused primarily on civilian populations. Further study is needed to understand whether these treatments are effective for Veteran populations. Objectives: Here, we examine the effectiveness of psychedelic-assisted therapy among trauma-exposed Special Operations Forces Veterans (SOFV) seeking treatment for cognitive and mental health problems in Mexico. Methods: Data were collected from an ibogaine and 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) clinical treatment program for SOFV with a history of trauma exposure. This clinical program collects prospective clinical program evaluation data, such as background characteristics, symptom severity, functioning (e.g., satisfaction with life, posttraumatic stress disorder symptoms, depression symptoms, anxiety symptoms, sleep disturbance, psychological flexibility, disability in functioning, cognitive functioning, neurobehavioral symptoms, anger, suicidal ideation), and substance persisting/enduring effects through online surveys at four timepoints (baseline/pre-treatment, one-, three-, and six-months after treatment). Results: The majority of the sample (n = 86; Mean Age = 42.88, SD = 7.88) were Caucasian (87.2%), non-Hispanic (89.5%), and males (100%). There were significant and large improvements in self-reported PTSD symptoms (p < .001, d = .414), depression (p < .001, d = .275), anxiety (p < .001, d = .276), insomnia severity (p < .001, d = .351), and post-concussive symptoms (p < .001, d = .389) as well as self-reported satisfaction with life (p < .001, d = .371), psychological flexibility (p < .001, d = .313) and cognitive functioning (p < .001, d = .265) from baseline to one-month follow-up. Conclusions: Data suggest combined ibogaine and 5-MeO-DMT assisted therapy has potential to provide rapid and robust changes in mental health functioning with a signal of durable therapeutic effects up to 6-months. Future research in controlled settings is warranted.

Sleep efficiency predicts improvements in fear extinction and PTSD symptoms during prolonged exposure for veterans with comorbid insomnia

Prolonged exposure (PE) is an evidenced-based psychotherapy for PTSD, but many Veterans fail to achieve a clinically meaningful response. Sleep issues are prevalent in Veterans and may interfere with PE by disrupting the learning and consolidation of fear extinction memories during PE exposures. Here, we examined whether changes in fear extinction across imaginal exposures and PTSD symptoms during PE were predicted by diary-assessed levels of nightly sleep efficiency (SE; i.e., percent of time in bed spent sleeping), which may indirectly index sleep fragmentation and sleep-facilitated memory processes. Participants were Veterans with PTSD and comorbid insomnia (N = 40) participating in a clinical trial of cognitive-behavioral therapy for insomnia plus PE. SE was measured via nightly sleep diaries, fear extinction was operationalized as a reduction in peak distress between weekly imaginal exposures, and PTSD symptoms were assessed bi-weekly. Cross-lagged panel models revealed that higher sleep efficiency during the week predicted lower peak distress at the subsequent imaginal exposure and lower PTSD symptoms at the subsequent assessment, whereas PTSD symptoms and peak distress did not predict subsequent sleep efficiency. Efficient sleep may facilitate fear extinction and PTSD reduction during PE. Targeting sleep efficiency could improve PE effectiveness for Veterans with comorbid insomnia.

Cortical activation predicts posttraumatic improvement in youth treated with TF-CBT or CCT

BackgroundIdentifying neural activation patterns that predict youths' treatment response may aid in the development of imaging-based assessment of emotion dysregulation following trauma and foster tailored intervention. Changes in cortical hemodynamic activity measured with functional near-infrared spectroscopy (fNIRS) may provide a time and cost-effective option for such work. We examined youths’ PTSD symptom change following treatment and tested if previously identified activation patterns would predict treatment response. MethodsYouth (N = 73, mean age = 12.97, SD = 3.09 years) were randomly assigned to trauma-focused cognitive behavioral therapy (TF-CBT), cue-centered therapy (CCT), or treatment as usual (TAU). Parents and youth reported on youth's PTSD symptoms at pre-intervention, post-intervention, and follow-up. Neuroimaging data (N = 31) assessed at pre-intervention were obtained while youth engaged in an emotion expression task. Treatment response slopes were calculated for youth's PTSD symptoms. ResultsOverall, PTSD symptoms decreased from pre-intervention through follow-up across conditions, with some evidence of relative benefit of TF-CBT and CCT over TAU but significant individual variation in treatment response. Cortical activation patterns were correlated with PTSD symptom improvement slopes (r = 0.53). In particular, cortical responses to fearful and neutral facial stimuli in six fNIRS channels in the bilateral dlPFC were important predictors of PTSD symptom improvement. ConclusionsThe use of fNIRS provides a method of monitoring and assessing cortical activation patterns in a relatively inexpensive and portable manner. Associations between functional activation and youths’ PTSD symptoms improvement may be a promising avenue for understanding emotion dysregulation in clinical populations.

One Year On: Evaluation of the Cambridgeshire and Peterborough Staff Mental Health Service, a Bespoke Mental Health Clinic for Healthcare Workers

AimsThe Staff Mental Health Service (SMHS) at the Cambridgeshire and Peterborough NHS Foundation Trust is a multidisciplinary team providing rapid access assessments and treatments to NHS staff in all roles. The service was launched in September 2020 and obtained recurrent funding in 2021. Previously we reported initial clinical findings from the service suggesting high rates of moderate to severe depression, anxiety, and post-traumatic stress symptoms (Kaser et al. 2021). In this report, we present the clinical and demographic findings, and post-treatment outcomes from the first-year evaluation of the SMHS.MethodsDemographic and clinical data were collected as part of service evaluation at the SMHS. Depression, anxiety, and posttraumatic stress symptoms were evaluated by Patient Health Questionnaire (PHQ-9), Generalised Anxiety Disorder Assessment (GAD-7), and Posttraumatic Symptom Checklist – Civilian Version (PCL-C). Non-parametric Wilcoxon rank test was used to compare pre- and post-treatment symptom scores.ResultsThe service received 515 referrals in the first year. 39.6% of the patients were off work at the time of the referral. 81.2% patients were female and 75.3% were of white ethnicity. Median time from referral to assessment was 14 days. According to the clinical data (n = 320), 85.3% of the patients had moderate to severe depressive symptoms (mean PHQ-9: 16.25 ± 6.1), and 80.9% of the patients had moderate to severe levels of anxiety symptoms (mean GAD-7: 13.62 ± 4.7). Staff patients endorsed high levels of traumatic stress with 82.5% scoring higher than the established cut-off (PCL-C &gt; 14) (PCL-C mean score: 19.14 ± 5.7). Analyses from patients completing treatment at the service showed significant improvements in depression (Z=−3.38, p = 0.001), anxiety (Z= -4.09, p &lt; 0.001), and PTSD symptoms (Z= -4.99, p &lt; 0.001).ConclusionThe Staff Mental Health Service had a persistent noticeable demand in its first year corresponding to two percent of the total workforce of the local trusts. Healthcare workers presenting to the service had high rates of moderate to severe depression, anxiety, and PTSD symptoms. Multidisciplinary treatment at the SMHS led to significant improvements in psychiatric symptoms. A health economics analysis of the service is currently underway.

0674 CPAP Adherence and Response to Cognitive Processing Therapy for PTSD in Veterans with Obstructive Sleep Apnea

Abstract Introduction Cognitive processing therapy (CPT) is a recommended first-line psychotherapy treatment for veterans with PTSD. Veterans with PTSD are at higher risk for sleep disorders including obstructive sleep apnea (OSA), and there is evidence that OSA can exacerbate PTSD and vice versa. Several studies have shown that CPAP use is associated with improvement in PTSD symptoms. CPT is an effective, yet time and resource intensive treatment option, making it critical to identify potential health factors impacting its efficacy. This retrospective chart analysis of veterans diagnosed with OSA and PTSD evaluated the effect of CPAP adherence on response to CPT. Methods Medical records of patients seen in a VA Health Care System were reviewed to identify veterans diagnosed with OSA and PTSD that received between 1-12 sessions of CPT with documented weekly PTSD Checklist for DSM-5 (PCL-5) scores, Patient Health Questionnaire-9 (PHQ-9) scores, and were issued a CPAP machine for OSA. Data collected included demographics, CPAP adherence (mean CPAP use, % days with greater than 4 hrs./night of CPAP use, mean residual apnea hypopnea index, mask leak), and PTSD symptoms (PCL-5 and PHQ-9 scores). For each outcome, we estimated a linear mixed-effects model; models for PCL-5 allowed heterogeneous residual variances for each veteran. Results This study identified 25 veterans receiving CPT for PTSD with access to a CPAP machine for OSA. The median age of patients was 43 years, median BMI was 35.6, and median residual AHI was 2.4. Patients received CPT for a median duration of 11.0 weeks. There was significant improvement in weekly PCL-5 and PHQ-9 scores over the course of CPT (both p &amp;lt; .001). CPAP adherence of at least 4 hrs./night for ≥70% of days did not significantly impact PCL-5 and PHQ-9 scores during CPT. Residual AHI and mask leak were not associated with PTSD symptoms during CPT. Conclusion While CPAP nonadherence appears to be a potential contributing factor to the reduced effectiveness of evidence-based treatments for veterans with PTSD, our study revealed significant improvement in PTSD symptoms during CPT regardless of CPAP adherence. Given the retrospective nature and small sample size of this study, further research is needed to expand on these findings. Support (If Any)
