Predicting Post-Traumatic Stress Disorder Treatment Response Using Heart Rate Variability to Virtual Reality Environment and Modified Stroop Task: An Exploratory Study.

Predicting treatment response can inform treatment decisions, expectations, and optimize use of mental health treatment resources. This study examined heart rate (HR), heart rate variability (HRV), and a modified Stroop task (mStroop) to predict post-traumatic stress disorder (PTSD) treatment response. We report on an observational, longitudinal study with 45 U.S. veterans in outpatient PTSD care, who had deployed to Iraq or Afghanistan. HR and HRV were collected before, during, and after virtual reality (VR) combat and civilian scenes. HRV recovery was defined as HRV after a 3-minute VR simulation minus HRV during a VR scene. mStroop threat variables included index scores for combat and general threat. Self-report data were collected at baseline and 6 months later. The outcome variable was the 17-item Clinician Administered PTSD Scale (CAPS). Controlling for baseline CAPS and number of combat experiences, the following baseline HRV recovery variables were significant predictors of 6-month CAPS: standard deviation of normal beat to beat interval (SDNN) after combat scene minus SDNN during combat scene and low-frequency (LF HRV) after civilian scene minus LF during civilian scene. HRV at rest, HR reactivity, HR recovery, and mStroop scores did not predict treatment response. In conclusion, HRV recovery variables in the context of a standardized VR stressor were significant predictors of PTSD treatment response after controlling for baseline CAPS and number of combat experiences. The direction of this relationship indicates that greater baseline HRV recovery predicts lower 6-month PTSD symptom severity. This was an exploratory study in need of replication.

A pilot test of Written Exposure Therapy for PTSD in residential substance use treatment.

BACKGROUND AND OBJECTIVES: Posttraumatic stress disorder (PTSD) is highly comorbid with substance use disorders (SUD) and can impede SUD recovery. Residential SUD treatment is a crucial opportunity to address PTSD. However, PTSD treatment is lacking in residential SUD care. METHODS: We conducted a nonrandomized feasibility study of Written Exposure Therapy (WET), a brief, evidence-based treatment for PTSD, with patients in residential SUD treatment. We assessed attitudes towards treatment (Credibility and Expectancy Questionnaire, Barriers to Treatment Participation Scale) and mental health indicators (PTSD Checklist for DSM-5, Trauma Coping Self-Efficacy, Difficulties in Emotion Regulation-Short Form, and Brief Assessment of Recovery Capital). RESULTS: Thirty of 49 eligible participants completed WET (61%) and 92% (n = 45) attended at least one WET session. Paired sample t-tests revealed significant posttreatment improvement across all mental health indicators, with medium to large effect sizes. DISCUSSION AND CONCLUSIONS: Attendance and completion rates compared favorably to prior exposure-based treatment for PTSD in SUD settings. Although causality cannot be inferred without a randomized controlled trial, mental health indicators, including PTSD, improved significantly following WET. SCIENTIFIC SIGNIFICANCE: These findings provide evidence that PTSD can be successfully treated in short-term residential care using brief exposure-based interventions, which is a crucial clinical need that has been minimally studied in the past.

Mental Health Clinician Community Clergy Collaboration to Address Moral Injury Symptoms: A Feasibility Study.

Moral injury (MI) symptoms (guilt, shame, isolation) can be associated with military experiences. While a degree of overlap is recognized between MI and posttraumatic stress disorder (PTSD) symptoms, MI symptoms do not always respond to evidence-based treatments for PTSD. Mental Health Clinician Community Chaplain Collaboration (MC4) was delivered by community clergy to address MI symptoms through facilitation of forgiveness and community reintegration. Thirteen veterans participated and the results suggested that MC4 was generally feasible and acceptable. However, it is unlikely community clergy time could keep up with demand. Shifting intervention delivery to Department of Veterans Affairs (VA) chaplains will alleviate many barriers experienced in this feasibility study.

An Evidence-Based Model for Disseminating-Implementing Coordinated Anxiety Learning and Management in Department of Veterans Affairs' Community-Based Outpatient Clinics.

PURPOSE: To explore the feasibility and utility of using a workshop, and supervision-consultation plus external facilitation to disseminate and implement cognitive-behavioral therapy in Veterans Affairs (VA) community-based outpatient clinics (CBOCs). METHODS: This study occurred in the context of a randomized controlled trial aimed at comparing 2 methods for implementing Coordinated Anxiety Learning Management (CALM) in VA CBOCs. A 3-phase (workshop, supervision-consultation, external facilitation) model was used to support 32 VA CBOC mental health providers in learning and adopting CALM in their clinical practice. Qualitative data describe training activities and the feasibility and utility of each training phase in addressing challenges to adopting CALM. FINDINGS: All 3 phases of the model were feasible to use with our sample of CBOC mental health providers. Providers reported challenges learning CALM during the workshop and concerns about not having enough training post-workshop to use CALM in practice. Providers primarily utilized supervision-consultation to tailor CALM to their practice, including learning how to prioritize a target disorder, "switch" the focus of treatment to a different disorder when comorbidities were present, and modify CALM sessions to fit shorter treatment visits. Providers primarily utilized external facilitation to further tailor CALM to their practice through implementation (eg, concrete help) and support-oriented help. Key lessons for implementing CALM in CBOCs are presented and discussed. CONCLUSIONS: Findings provide initial evidence for the feasibility and utility of using each component of a facilitation-enhanced training model to promote CBOC VA providers' implementation of a computer and manual version of CALM in their practice.

Mental Health Clinician and Community Clergy Collaboration to Address Moral Injury in Veterans and the Role of the Veterans Affairs Chaplain.

Moral injury in veterans with posttraumatic stress disorder includes symptoms of guilt and shame, and these symptoms are often not responsive to evidence-based mental health treatments. Clergy provide a pathway for relieving the guilt and shame. However, there is a long history of mistrust between clergy and mental health clinicians and not enough Veterans Health Administration chaplains to meet this need. The goal of this study was to gather qualitative interview data from relevant stakeholders regarding whether and how Veterans Affairs (VA) mental health clinicians and community clergy could collaborate to address moral injury issues such as guilt and shame in veterans being treated for posttraumatic stress disorder. The stakeholders for this study were veterans, mental health clinicians, and clergy. Qualitative data were organized into three domains: barriers, facilitators, and intervention suggestions. These data were used to develop a new intervention for moral injury that includes a central role for the Veterans Affairs chaplain.

The effect of cognitive processing therapy on cognitions: impact statement coding.

This study compared the cognitions of 37 female rape survivors before and after completing cognitive processing therapy (CPT). It was hypothesized that CPT would be associated with reductions in posttraumatic stress disorder (PTSD) symptoms and problematic (i.e., assimilated and overaccommodated) thoughts as well as increases in the number of realistic (i.e., accommodated) cognitions. Cognitions were assessed via coding and analyses of participants' written impact statements at the beginning and end of treatment. Posttraumatic stress disorder symptoms were assessed with the Clinician-Administered PTSD Scale and PTSD Symptom Scale. As predicted, there were significant increases in accommodated statements and significant decreases in overaccommodated and assimilated statements. The hypothesis that cognitive changes would be related to symptom reduction was partially supported.

Psychometric properties of the PTSD Checklist-Civilian Version.

We examined the psychometric properties of the PTSD Checklist (PCL), a self-report instrument designed to assess symptoms of posttraumatic stress disorder. Three hundred ninety-two participants recruited in a university setting completed the PCL in addition to several well-established self-report instruments designed to assess various forms of psychopathology (e.g., depression, general anxiety, PTSD). Ninety participants returned for readministration of selected measures. Findings provided support for psychometric properties of the PCL, including internal consistency, test-retest reliability, convergent validity, and discriminant validity. Additional strengths of the PCL are discussed.
