The Development of a Brief Version of the Posttraumatic Cognitions Inventory (PTCI-9)

Posttraumatic cognition change trajectories in veterans with PTSD who completed an intensive Cognitive Processing Therapy treatment program

Negative posttraumatic cognitions (NPCs) have been linked to symptoms of PTSD and are an important target of cognitive behavioral treatments for PTSD, including Cognitive Processing Therapy (CPT). Yet to be explored are the different change trajectories of NPCs during CPT. Knowledge of such change trajectories could elucidate common NPC change processes within CPT and their relationship to PTSD symptom severity. We examined NPC change trajectories in a group of 443 veterans who completed a 2-week intensive CPT program. We identified four NPC trajectory groups termed start high end high, start high end moderate, start moderate end low, and start low end low. Most of the groups showed an increase in NPCs at the midpoint of treatment before ultimately decreasing. As predicted, baseline PTSD symptom severity predicted change trajectory group membership. Also, NPC change trajectories were associated with PTSD severity at the end of treatment such that individuals in smaller NPC change groups had higher PTSD symptoms at the end of treatment, and vice versa. Clinicians can use this knowledge to make predictions of a particular client's NPC change trajectory and set expectations for what progress in treatment may look like, including normalizing increases in NPCs from the start of treatment.

From identity-based distress to thinking "I am better off being dead:" Minority stress, posttraumatic cognitions, and suicidal ideation

BACKGROUND

Suicidal ideation (SI) disproportionately impacts individuals with minoritized race/ethnicity, gender, and sexual orientation. Minority stress - i.e., traumatic, insidious distress that results from acts of discrimination - may lead to the formation of posttraumatic cognitions that may generalize to suicidal ideation, elevating SI risk in minoritized populations. The current study aimed to test this potential relationship by examining whether minority stress and posttraumatic cognitions accounted for the association between discrimination and SI.

METHODS

Series of structural equation models, including multigroup confirmatory factor analyses conducted to test invariance of latent constructs, were estimated on cross-sectional data collected from minoritized young adults (n = 337).

RESULTS

Results supported the hypothesized model: experience of discrimination indirectly associated with SI via correlations shared between minority stress and posttraumatic cognitions. Experiences of discrimination lacked a significant correlation with SI while accounting for minority stress and posttraumatic cognition variance. Invariance testing conducted to account for applicability of the model across race, ethnicity, sexual orientation, and plurality of minoritized identities all demonstrated that the model was applicable across these identity dimensions.

LIMITATIONS

Granular inspection of identity dimensions was infeasible due to sample size and causal inferences cannot be drawn given cross-sectional nature of the data used.

CONCLUSIONS

Posttraumatic cognitions within the context of discrimination may be effective treatment targets for minoritized individuals who present with minority stress and SI. Future studies should aim to replicate such findings longitudinally to infer temporality.

International Trauma Questionnaire and Posttraumatic Cognitions Inventory-9: validity evidence and measurement invariance of their Brazilian versions

BACKGROUND

The International Trauma Questionnaire (ITQ) is used to measure posttraumatic stress disorder (PTSD) and complex posttraumatic stress disorder (CPTSD) symptoms, and the Posttraumatic Cognitions Inventory-9 (PTCI-9) is used to measure posttraumatic cognitions. Both tools have been translated for use in Brazil. However, the psychometric properties of the Brazilian versions were not investigated, and no study has verified the invariance of these tools for many traumatic event types.

OBJECTIVE

This study examined the validity, reliability, and measurement invariance of the Brazilian versions of the ITQ and the PTCI-9 for trauma type, gender, race, age group, education level, and geographical region.

METHODS

A total of 2,111 people (67.74% women) participated in an online survey. The scale models were tested via confirmatory factor analyses and measurement invariance through multigroup analyses. Pearson's correlation analyses were used to examine the relationships between PTSD, CPTSD, posttraumatic cognitions, and depressive symptoms.

RESULTS

Except for the affective dysregulation factor, the reliabilities of the ITQ and PTCI-9 dimensions were adequate. Models with six correlated dimensions for the ITQ and three correlated dimensions for the PTCI-9 showed adequate fit to the data. The ITQ and PTCI-9 exhibited scalar invariance for gender, race, age group, education level, and geographical region. The ITQ also demonstrated full invariance for trauma type. The factors of both instruments were related to each other and to depressive symptoms, with higher effect sizes for posttraumatic cognitions and complex posttraumatic stress disorder symptoms.

CONCLUSION

We recommend using the Brazilian versions of the ITQ and PTCI-9, which are crucial tools for assessing and treating trauma-related disorders.

The Effects of the Processing of Positive Memories Technique on Posttrauma Affect and Cognitions Among Survivors of Trauma: Protocol for a Daily Diary Study

BACKGROUND

The Processing of Positive Memories Technique (PPMT) is a promising new treatment approach for posttraumatic stress disorder (PTSD), which involves detailed narration and processing of specific positive autobiographical memories. Indeed, preliminary case-series studies have found reductions in PTSD symptoms, negative affect, and negative cognitions among survivors of trauma who have received PPMT. However, PPMT's effects have not been investigated at the daily level. In this study, we describe the protocol for a study that will examine the daily-level impacts of PPMT in a trauma-exposed, nonclinical community sample.

OBJECTIVE

This study uses an innovative research protocol that combines case-series design and daily diary approaches to examine changes in daily affect, daily cognitions, and daily PTSD symptoms pre- and post-PPMT. We hypothesize that at the daily level, in comparison to their own pre-PPMT levels, following the PPMT intervention, participants will report (1) a lower count of endorsed daily PTSD symptoms, (2) increases in daily positive affect and decreases in daily negative affect, (3) increases in positive affect reactivity to daily positive events, and (4) decreases in daily posttrauma cognitions.

METHODS

We are currently recruiting participants (target n=70) from a metroplex in the southwest United States. Following a screening survey, eligible participants complete a preintervention baseline survey, followed by 21 daily surveys in their natural environments. Then, they receive 4 PPMT sessions on a weekly basis. After the conclusion of the PPMT intervention, participants complete a postintervention outcome survey and 21 daily surveys. To compare daily affect, daily cognitions, and daily PTSD symptoms before and after PPMT, we will use the daily diary report data and conduct multilevel random intercepts and slopes linear regression models.

RESULTS

Data collection was initiated in March 2022 and is expected to end by June 2024. As of November 28, 2023, a total of 515 participants had consented to the study in the screening phase. No analyses will be conducted until data collection has been completed.

CONCLUSIONS

Study findings could clarify whether deficits in positive autobiographical memory processes may also characterize PTSD alongside deficits in traumatic memory processes. Furthermore, PPMT could be an additional therapeutic tool for clinicians to help clients reduce posttraumatic distress in their everyday lives.

Massed cognitive processing therapy for combat-related posttraumatic stress disorder: Study design and methodology of a non-inferiority randomized controlled trial

BACKGROUND

Posttraumatic stress disorder (PTSD) is prevalent among military personnel. Cognitive processing therapy (CPT) is identified as one of the most effective treatments for PTSD, although smaller effects have been found in military populations. High rates of dropout from treatment may contribute to reduced efficacy, and military personnel may face unique barriers to treatment completion. One method of improving efficacy may be to reduce dropout by decreasing the time required to receive a full dose of treatment. This paper describes the design and methodology of the first randomized clinical trial testing whether CPT delivered in an intensive format is non-inferior to standard delivery of CPT.

METHOD

Participants are 140 active duty service members randomized to receive CPT in a 5-day combined group and individual intensive outpatient format (MCPT) or standard CPT (delivered individually twice weekly over 6 weeks). Participants are assessed at baseline, and 1 month, 4 months, and 1 year following the conclusion of the therapy. Reduction in PTSD symptomatology is the primary outcome of interest. Secondary outcomes include comorbid psychological symptoms, health, and functioning. A secondary objective is to examine predictors of treatment outcome to determine which service members benefit most from which treatment modality.

CONCLUSION

If determined to be non-inferior, MCPT would provide an efficient and accessible modality of evidence-based PTSD treatment. This therapy format would improve access to care by reducing the amount of time required for treatment and improving symptoms and functioning more rapidly, thereby minimizing interference with work-related activities and disruption to the mission.

Impacts of repeated retrieval of positive and neutral memories on posttrauma health: An investigative pilot study

BACKGROUND AND OBJECTIVES

Evidence indicates that positive memory processes play a role in the etiology and maintenance of posttraumatic stress symptoms (PTSS) and related posttrauma health indicators. To extend this research, the current pilot study examined if repeated retrieval of positive vs. neutral memories was associated with (1) less PTSS and depression severity; and (2) improved affect and cognitions (fewer posttrauma cognitions, more positively-valenced affect, less negatively-valenced affect, less negative affect interference, less anhedonia, retrieval of more positive specific memories, retrieval of fewer negative specific memories).

METHODS

Twenty-five trauma-exposed participants were randomly assigned to a positive or neutral memory task condition. They participated in four weekly experimental sessions facilitated by an experimenter virtually; each consecutive session was separated by 6-8 days. We conducted mixed between-within subjects ANOVAs to examine study hypotheses.

RESULTS

No interaction effects were significant. There were significant main effects of time on PTSS and depression severity, posttrauma cognitions, positively-valenced and negatively-valenced affect, and negative affect interference.

LIMITATIONS

We used self-report measures, small and non-clinical sample with limited demographic diversity, and virtual format; did not record memory narratives; and did not have a trauma memory condition.

CONCLUSIONS

Based on pilot data, our findings suggest that individuals who retrieve positive or neutral memories repeatedly may report less PTSS and depression severity, fewer posttrauma cognitions, and improved affect. Results provide an impetus to examine impacts of and mechanisms underlying memory interventions (beyond a sole focus on negatively-valenced memories) in trauma work.

Using the multiphase optimization strategy to adapt cognitive processing therapy (CPT MOST): study protocol for a randomized controlled factorial experiment

BACKGROUND

Approximately ten percent of US military veterans suffer from posttraumatic stress disorder (PTSD). Cognitive processing therapy (CPT) is a highly effective, evidence-based, first-line treatment for PTSD that has been widely adopted by the Department of Veterans Affairs (VA). CPT consists of discrete therapeutic components delivered across 12 sessions, but most veterans (up to 70%) never reach completion, and those who discontinue therapy receive only four sessions on average. Unfortunately, veterans who drop out prematurely may never receive the most effective components of CPT. Thus, there is an urgent need to use empirical approaches to identify the most effective components of CPT so CPT can be adapted into a briefer format.

METHODS

The multiphase optimization strategy (MOST) is an innovative, engineering-inspired framework that uses an optimization trial to assess the performance of individual intervention components within a multicomponent intervention such as CPT. Here we use a fractional factorial optimization trial to identify and retain the most effective intervention components to form a refined, abbreviated CPT intervention package. Specifically, we used a 16-condition fractional factorial experiment with 270 veterans (N = 270) at three VA Medical Centers to test the effectiveness of each of the five CPT components and each two-way interaction between components. This factorial design will identify which CPT components contribute meaningfully to a reduction in PTSD symptoms, as measured by PTSD symptom reduction on the Clinician-Administered PTSD Scale for DSM-5, across 6 months of follow-up. It will also identify mediators and moderators of component effectiveness.

DISCUSSION

There is an urgent need to adapt CPT into a briefer format using empirical approaches to identify its most effective components. A brief format of CPT may reduce attrition and improve efficiency, enabling providers to treat more patients with PTSD. The refined intervention package will be evaluated in a future large-scale, fully-powered effectiveness trial. Pending demonstration of effectiveness, the refined intervention can be disseminated through the VA CPT training program.

Heightened threat perceptions and reduced stability in anxiety and fear among U.S. adults who carry handguns

Firearm carrying is often motivated to provide safety and is correlated with increased anxiety related to elevated perceptions of the world as a dangerous place. No studies have investigated affective states among firearm owners as they occur in their natural environments. This study used ecological momentary assessment (EMA) to examine cognitive-affective states among firearm owners who carry handguns outside their home (n = 35), firearm owners who do not carry (n = 47), and non-firearm owners (n = 62). Participants completed a self-report questionnaire at baseline followed by EMA surveys of mood state with the Positive and Negative Affect Scale (PANAS) 6 times per day for 28 consecutive days. Carry handgun owners reported significantly higher threat perceptions, measured with the negative cognitions about the world subscale of the shortened Posttraumatic Cognitions Inventory (PTCI), than no-carry handgun owners (Mdiff=2.0, 95% CI=0.8-2.0, d=0.45, p = .001) and non-owners (Mdiff=1.8, 95% CI=0.6-2.9, d=0.42, p = .003). Groups did not significantly differ in mean momentary mood ratings assessed via EMA but stability in high-arousal negative arousal was significantly reduced among carry handgun owners (F(2, 150)= 3.7, p = .026). Results suggest firearm owners who carry handguns view the world as especially dangerous, are more likely to experience shifts in anxiety and fear, and take longer to recover from periods of elevated anxiety and fear.

Testing adaptive interventions to improve PTSD treatment outcomes in Federally Qualified Health Centers: Protocol for a randomized clinical trial

BACKGROUND

Posttraumatic stress disorder (PTSD) disproportionately affects low-income individuals and is untreated in 70% of those affected. One third of low-income Americans are treated in Federally Qualified Health Centers (FQHCs), which do not have the capacity to provide all patients with first-line treatments such as Prolonged Exposure (PE). To address this problem, FQHCs could use low-intensity interventions (e.g., Clinician-Supported PTSD Coach: CS PTSD Coach) and medium-intensity interventions (e.g., PE for Primary Care: PE-PC) to treat PTSD with fewer resources. However, some patients will still require high-intensity treatments (e.g., full-length PE) for sustained clinical benefit. Thus, there is a critical need to develop stepped-care models for PTSD in FQHCs.

METHOD

We are conducting a Sequential, Multiple Assignment, Randomized Trial (SMART) with 430 adults with PTSD in FQHCs. Participants are initially randomized to CS PTSD Coach or PE-PC. After four sessions, early responders step down to lower frequency interaction within their assigned initial treatment strategy. Slow responders are re-randomized to either continue their initial treatment strategy or step up to Full PE for an additional eight weeks. The specific aims are to test the effectiveness of initiating treatment with PE-PC versus CS PTSD Coach in reducing PTSD symptoms and to test the effectiveness of second-stage strategies (continue versus step-up to Full PE) for slow responders.

CONCLUSIONS

This project will provide critical evidence to inform the development of an effective stepped-care model for PTSD. Testing scalable, sustainable sequences of PTSD treatments delivered in low-resource community health centers will improve clinical practice for PTSD.

Examining characteristics and experiences of Black firearm owners

OBJECTIVE

The present study sought to better understand the characteristics of those who own firearms in the Black community; and to understand how Black firearm owners differ from nonfirearm owning Black individuals on a variety of variables related to safety, threat concerns, and suicide risk.

METHODS

Two samples were utilized in this study. The first was a subsample of those who identified as Black from a nationally representative sample (N = 502) seeking to understand firearm ownership within the United States. The second used a subsample of those who identified as Black (N = 1086) from a representative sample from New Jersey, Minnesota, and Mississippi. Variables related to safety and threat concerns were included in the second sample.

RESULTS

In both samples, multiple demographic variables, such as being a woman and having higher education, predicted firearm ownership. In the second sample, experiences of everyday discrimination and crime experiences were associated with firearm ownership. Additionally, Black firearm owners reported significantly more suicidal ideation than Black nonfirearm owners.

CONCLUSION

The findings demonstrate the unique characteristics and experiences of Black firearm owners and show that firearm ownership is associated with increased suicide risk factors for Black adults. Findings should be used to advocate for the creation of more culturally relevant suicide prevention and firearm means safety strategies.

Morally injurious events among aid workers: examining the indirect effect of negative cognitions and self-care in associations with mental health indicators

Introduction

Potentially morally injurious events (PMIE) are events that violate one's deeply held moral values or beliefs, and that have the potential to create significant inner conflict and psychological distress. PMIE have been recognized as an important psychological risk factor in many high-risk occupational groups. However, no study to date has investigated how PMIE relate to the mental health of aid workers. Furthermore, little is known about the mechanisms by which PMIE might be associated with mental health indicators.

Methods

Participants were 243 aid workers (72% female; M age = 39.31) who had completed at least one aid assignment (M = 8.17). They completed an online questionnaire about their PMIE, trauma history, and mental health. A structural equation model was constructed to examine the roles of negative cognitions and subsequent self-care behaviors in the relationship between PMIE and PTSD symptoms, depression symptoms, and posttraumatic growth, above and beyond the contribution of potentially traumatic events.

Results

Within the model, the indirect effect through negative cognitions fully accounted for the associations between PMIE and symptoms of PTSD and depression. For the association between PMIE and posttraumatic growth, two indirect effects emerged: the first through negative cognitions and subsequent self-care and, the second, through self-care alone.

Discussion

This study highlighted PMIE as a novel psychological risk factor for aid workers and pointed to two possible mechanisms by which these events may lead to PTSD, depression, and posttraumatic growth. This study adds to the current understanding of how high-risk occupational groups adapt psychologically to PMIE.

Changes in trauma-related cognitions predict subsequent symptom improvement during prolonged exposure in patients with childhood abuse-related PTSD

Change in negative posttraumatic cognitions is a proposed mechanism through which Prolonged Exposure (PE) leads to symptom reduction of posttraumatic stress disorder (PTSD). A strong case for posttraumatic cognitions as a change mechanism in PTSD treatment can be made by establishing temporal precedence of change in cognitions. The current study examines the temporal relationship between change in posttraumatic cognitions and PTSD symptoms during PE, using the Posttraumatic Cognitions Inventory. Patients with DSM-5 defined PTSD following childhood abuse (N = 83) received a maximum of 14-16 sessions of PE. Clinician-rated PTSD symptom severity and posttraumatic cognitions were assessed at baseline, week 4, 8, and 16 (post-treatment). Using time-lagged mixed effect regression models, we found that posttraumatic cognitions predicted subsequent PTSD symptom improvement. Notably, when using the items of an abbreviated version of the PTCI (PTCI-9), we found a mutual relationship between posttraumatic cognitions and PTSD symptom improvement. Crucially, the effect of change in cognitions on PTSD symptom change was greater than the reverse effect. The current findings corroborate change in posttraumatic cognitions as a change process during PE, but cognitions and symptoms cannot be completely separated. The PTCI-9 is a short instrument that appears suitable to track cognitive change over time.

Effect of adding a positive memories’ module in a trauma-focused cognitive-behavioural treatment for female survivors of intimate partner violence: trial protocol

Background

Trauma-focused cognitive-behavioural treatments have been proven to be effective for reducing symptoms in female survivors of intimate partner violence (IPV), although they still present some difficulties (e.g. significant drop-out rates, low adherence). Based on existing evidence about the difficulty of accessing memories of positive experiences among these women, we considered integrating positive memory evocation in trauma-focused treatments. The present study aims to test the effect of adding a positive memory module to trauma-focused CBT for female survivors of IPV.

Methods

The study is a single-blind, randomized controlled trial (RCT) comparing two trauma-focused CBT (with and without a positive memory module) for female survivors of IPV and a wait-list condition (superiority trial), including pretreatment and posttreatment measures, and follow-ups at 3, 6 and 12 months. Assessors of treatment outcome will be blinded to the trial arm. We aim to recruit 135 participants who will be randomized to one of the experimental conditions. The primary outcome is PTSD symptom severity. Secondary outcome measures include IPV, attitudes towards IPV, posttraumatic cognitions, centrality of trauma, self-concept, positive and negative affect, depression, anxiety, emotional dysregulation or health-related quality of life, as well as satisfaction with treatment. Moreover, adherence to and satisfaction with treatment will be considered.

Discussion

This study first analyses the effect of including positive memory evocation into a trauma-focused treatment for female survivors of IPV. This strategy aims to improve the effect of the treatments and enhance the healing of the trauma by developing a more integrated and emotionally modulated autobiographical narrative that contributes to the recovery and well-being of the victims.

Trauma-focused therapies for post-traumatic stress in psychosis: study protocol for the RE.PROCESS randomized controlled trial

INTRODUCTION

Many people with psychotic disorders experience symptoms of post-traumatic stress disorder (PTSD). In recent years, several trauma-focused therapies (TFTs), including cognitive restructuring (CR), prolonged exposure (PE), and eye movement desensitization and reprocessing (EMDR) have been studied and found to be safe and effective in reducing PTSD symptoms in individuals with psychosis. However, studies were conducted in different countries, with varying inclusion criteria, therapy duration, control groups, and trial outcomes. RE.PROCESS will be the first study to compare the impact of CR, PE, and EMDR with a waiting list control condition within the same context.

METHODS AND ANALYSIS

This is the protocol of a pragmatic, single-blind, multicentre, superiority randomized controlled trial, in which CR, PE, and EMDR are compared to a waiting list control condition for TFT (WL) in a naturalistic treatment setting. Inclusion criteria are as follows: age ≥ 16 years; meeting full DSM-5 diagnostic criteria for PTSD on the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), with a total CAPS score ≥ 23; and a psychotic disorder in the schizophrenia spectrum confirmed by the Structured Clinical Interview for DSM-5 (SCID-5). Participants (N=200) will be randomly allocated to 16 sessions of one of the TFTs or WL, in addition to receiving treatment as usual (TAU) for psychosis. The primary objective is to compare the effects of CR, PE, and EMDR to WL on researcher-rated severity of PTSD symptoms over time from baseline to 6-month follow-up. Secondary objectives are to examine these effects at the separate time-points (i.e., mid-treatment, post-treatment, and at 6-month follow-up) and to test the effects for clinician-rated presence of PTSD diagnosis, and self-rated severity of (complex) PTSD symptoms.

DISCUSSION

This is the first RCT to directly compare the effects of CR, PE, and EMDR within the same context to TAU on PTSD symptoms in individuals with psychosis and PTSD. Secondary effects on clinical and functional outcomes will be investigated both directly after therapy and long term.

Translation, validation and exploration of the factor structure in the French version of the Posttraumatic Cognitions Inventory (PTCI)

OBJECTIVES

In order to validate a French version of the PTCI, this study investigates two objectives using two French speaking samples: (1) test 10 factor structures identified in prior studies, and (2) assess the other psychometric properties of the best fitting factor structure.

METHOD

The PTCI was translated in French using a reverse translation method and administered to 202 university students and 114 aid workers. Suitability indexes of the appropriate factor structures previously identified in prior studies were examined. Internal consistency, correlations between subscales and convergent, divergent and discriminant validities in the most appropriate structure were evaluated.

RESULTS

Results support that only Wells et al.'s short 9-item version of the PTCI and three factors shows excellent suitability indexes. This version also outlines an excellent internal consistency and solid convergent, divergent, and discriminant validities.

CONCLUSIONS

This study confirms the empirical validity, fidelity, and utility of Wells et al.'s short version of the PTCI. This is the first PTCI French validation, which is a major advantage when it comes to assess posttraumatic cognitions in French trauma victims.

Multisite randomised controlled trial of trauma-focused cognitive behaviour therapy for psychosis to reduce post-traumatic stress symptoms in people with co-morbid post-traumatic stress disorder and psychosis, compared to treatment as usual: study protocol for the STAR (Study of Trauma And Recovery) trial

Background

People with psychosis have high rates of trauma, with a post-traumatic stress disorder (PTSD) prevalence rate of approximately 15%, which exacerbates psychotic symptoms such as delusions and hallucinations. Pilot studies have shown that trauma-focused (TF) psychological therapies can be safe and effective in such individuals. This trial, the largest to date, will evaluate the clinical effectiveness of a TF therapy integrated with cognitive behaviour therapy for psychosis (TF-CBTp) on post-traumatic stress symptoms in people with psychosis. The secondary aims are to compare groups on cost-effectiveness; ascertain whether TF-CBTp impacts on a range of other meaningful outcomes; determine whether therapy effects endure; and determine acceptability of the therapy in participants and therapists.

Methods

Rater-blind, parallel arm, pragmatic randomised controlled trial comparing TF-CBTp + treatment as usual (TAU) to TAU only. Adults (N = 300) with distressing post-traumatic stress and psychosis symptoms from five mental health Trusts (60 per site) will be randomised to the two groups. Therapy will be manualised, lasting 9 months (m) with trained therapists. We will assess PTSD symptom severity (primary outcome); percentage who show loss of PTSD diagnosis and clinically significant change; psychosis symptoms; emotional well-being; substance use; suicidal ideation; psychological recovery; social functioning; health-related quality of life; service use, a total of four times: before randomisation; 4 m (mid-therapy); 9 m (end of therapy; primary end point); 24 m (15 m after end of therapy) post-randomisation. Four 3-monthly phone calls will be made between 9 m and 24 m assessment points, to collect service use over the previous 3 months. Therapy acceptability will be assessed through qualitative interviews with participants (N = 35) and therapists (N = 5–10). An internal pilot will ensure integrity of trial recruitment and outcome data, as well as therapy protocol safety and adherence. Data will be analysed following intention-to-treat principles using generalised linear mixed models and reported according to Consolidated Standards of Reporting Trials-Social and Psychological Interventions Statement.

Discussion

The proposed intervention has the potential to provide significant patient benefit in terms of reductions in distressing symptoms of post-traumatic stress, psychosis, and emotional problems; enable clinicians to implement trauma-focused therapy confidently in this population; and be cost-effective compared to TAU through reduced service use.

Changes in Trauma-Related Cognitions and Emotions After Eliciting Moral Elevation: Examining the Effects of Viewing Others' Virtuous Behavior on Veterans with PTSD

Moral elevation is described as feeling inspired after witnessing someone perform a virtuous act. Past work suggests the features of moral elevation may be contrary to PTSD, yet few studies have directly tested its impact on relevant symptoms. This experimental study assessed changes in trauma-related cognitions and emotions from after a trauma reminder task to after an elevation induction exercise. We hypothesized that higher elevation after the induction exercise would be associated with greater reductions in cognitions and emotions. Veterans with probable PTSD (N = 38) completed measures of trauma-related cognitions and emotions, once after a written trauma narrative exercise (T1) and again after watching two videos designed to elicit elevation (T2). Veterans also completed measures of state elevation after each video. Results suggest veterans experienced small, significant decreases in self-blame (d = 0.36) and negative beliefs about others (d = 0.46), and medium, significant decreases in guilt (d = 0.68), shame (d = 0.60), and negative beliefs about self (d = 0.69) between T1 and T2. As hypothesized, higher elevation was associated with significantly greater reductions in multiple outcomes above and beyond the effects of general positive affect. Specifically, there were medium effects for changes in shame (β = -0.42, SE = 0.17, p = .019, Δf ² = 0.25), negative view of others (β = -0.34, SE = 0.16, p = .044, Δf ² = 0.20), and a large effect for changes in negative view of self (β = -0.31, SE = 0.13, p = .019, Δf ² = 0.54). These findings suggest elevation may be well-suited to target trauma-related symptoms and future research should further examine its clinical utility.

Adaptation of the Texas Christian University Organisational Readiness for Change Short Form (TCU-ORC-SF) for use in primary health facilities in South Africa

OBJECTIVES

The Texas Christian University Organisational Readiness for Change Scale (TCU-ORC) assesses factors influencing adoption of evidence-based practices. It has not been validated in low-income and middle-income countries (LMIC). This study assessed its psychometric properties in a South African setting with the aim of adapting it into a shorter measure.

METHODS

This study was conducted in 24 South African primary healthcare clinics in the Western Cape Province. The TCU-ORC and two other measures, the Organisational Readiness to Change Assessment (ORCA) and the Checklist for Assessing Readiness for Implementation (CARI) were administered. The questionnaire was readministered after 2 weeks to obtain data on test-retest reliability. Three hundred and ninety-five surveys were completed: 281 participants completed the first survey, and 118 recompleted the assessments.

RESULTS

We used exploratory factor analysis (EFA) to identify latent dimensions represented in the data. Cronbach's alpha for each subscale was assessed and we examined the extent to which the subscales and total scale scores for the first and retest surveys correlated. Convergent validity was assessed by the correlation coefficient between the TCU-ORC, ORCA and CARI total scale scores. EFA resulted in a three-factor solution. The three subscales proposed are Clinic Organisational Climate (8 items), Motivational Readiness for Change (13 items) and Individual Change Efficacy (5 items) (26 items total). Cronbach's alpha for each subscale was >0.80. The overall shortened scale had a test-retest correlation of r=0.80, p<0.01, acceptable convergent validity with the ORCA scale (r=0.56, p<0.05), moderate convergence with the CARI (r=39, p<0.05) and strong correlation with the original scale (r=0.79, p<0.05).

CONCLUSIONS

This study presents the first psychometric data on the TCU-ORC from an LMIC. The proposed shortened tool may be more feasible for use in LMICs.

Negative Cognitions and Emotional Distress Following Job Loss: Development and Validation of the Beliefs About Loss of Work (BLOW) Scale

Negative cognitions following job loss can contribute to emotional distress by motivating individuals to adopt coping styles that reduce stress in the short run while obstructing adjustment in the long run. It is unclear which specific cognitions are related to symptoms of complicated grief, depression, and anxiety following job loss. To fill this gap, this study introduces the Beliefs about Loss of Work (BLOW) scale and examines its psychometric properties. We recruited 222 Dutch workers who had lost their job, including 70 men and 152 women, with an average age of 52.5 years. Confirmatory factor analyses revealed that a second-order eight-factor model had the best fit to the data. The BLOW scale is a reliable instrument with a good convergent and divergent validity. This instrument may stimulate research on mechanisms involved in job loss-related distress and could inform the development of interventions to reduce this distress.

Mindful attention awareness and cognitive defusion are indirectly associated with less PTSD-like symptoms via reduced maladaptive posttraumatic cognitions and avoidance coping

Recently, the effects of mindfulness-based interventions for posttraumatic stress disorder (PTSD) have been studied. However, we lack knowledge of the processes or mechanisms through which mindfulness influences resilience or promotes recovery following exposure to trauma. In this study, we examine the process by which mindfulness and cognitive-behavioral factors such as posttraumatic negative cognition and avoidance behaviors are associated with reduced PTSD-like symptoms. A questionnaire survey was conducted with 885 university students, using the Trauma Experience Questionnaire, Mindful Attention Awareness Scale, Cognitive Fusion Questionnaire, Post-Traumatic Stress Disorder Checklist, revised Ways of Coping Checklist, and a brief version of the Posttraumatic Cognitions Inventory. Data from 254 participants who experienced trauma with PTSD-like symptoms were analyzed. The final model using SEM indicated no direct association of mindful attention awareness on PTSD-like symptoms, a small direct association of cognitive defusion on PTSD-like symptoms, and a large indirect association mediated by posttraumatic negative cognitions and avoidance coping. Owing to the study’s cross-sectional design, strong conclusions cannot be drawn regarding the causal relationship of mindfulness and cognitive-behavioral factors or generalizations. However, our findings suggest that it would be worthwhile to continue to clarify the mechanism of mindfulness and to investigate its use in the treatment of PTSD. In the future, a highly accurate study design will hopefully be used to examine the mechanisms of several different factors associated with improvement in posttraumatic stress symptoms, preferably including them in the same model.

Negative affective responses to positive events and stimuli in patients with complex dissociative disorders: a mixed-methods pilot study

BACKGROUND

Research suggests that individuals exposed to (childhood) trauma are not only unable to experience pleasure, known as hedonic deficit (HD), but also experience 'negative affective responses to positive events', known as negative affective interference (NAI). The clinical relevance and prognostic features of NAI have increasingly been recognized. To date, no studies have focused on NAI in patients with complex dissociative disorders (CDDs) who were abused early in life.

OBJECTIVE

In this pilot study, we quantitatively and qualitatively investigated how NAI is related to trauma-related symptoms and how this phenomenon can be understood in a selected group of adult CDD patients.

METHOD

CDD patients (N = 25) referred to an inpatient dissociation-focused treatment programme completed the Hedonic Deficit & Interference Scale (HDIS), and measures of trauma-related symptoms and interpersonal functioning, as well as a qualitative questionnaire addressing possible inner conflicts and phobias with respect to the experience of positive events. A convergent mixed-methods design was used to obtain different but complementary data on NAI to gain a more complete understanding of the phenomenon.

RESULTS

The quantitative analyses showed a significant relationship between NAI and trauma-related symptoms and interpersonal functioning. NAI seems to be more strongly associated with these symptoms than HD. The qualitative analysis revealed three themes - fear, shame, and aggressive 'parts' - preventing positive emotions, which provided a possible interpretation of the quantitative results. The integrated findings were discussed in light of theories of structural dissociation of the personality and attachment.

CONCLUSIONS

These findings indicate that NAI is related to a spectrum of trauma-related symptoms and interpersonal functioning in patients with a CDD to a larger degree than HD and that different dissociative identities are involved. Studies of the relationship between changes in HDIS (particularly the NAI subscale) and changes in trauma-related symptoms and interpersonal functioning following treatment are warranted.

Threat perceptions and the intention to acquire firearms

Firearm sales have surged during COVID-19, raising concerns about a coming wave of suicide deaths. Little is known, however, about the individuals considering acquiring firearms during the pandemic. Recent research has highlighted that individuals considering acquiring firearms may be motivated by exaggerated threat expectancies. In a sample of 3,500 Americans matched to 2010 United States Census data, we compared individuals intending to buy firearms in the coming 12 months (assessed in late June and early July 2020) to those undecided or not planning to acquire firearms on a range of demographic, anxiety, and firearm ownership variables. Our results indicated that those intending to acquire a firearm in the next twelve months are less tolerant of uncertainty, endorse exaggerated threat expectancies, and are experiencing more severe COVID-19 specific fears. Individuals intending to purchase firearms were also more likely to have experienced suicidal ideation in the past year, to have worked in law enforcement, and to have been considered essential workers during COVID-19. Furthermore, such individuals were more likely to already own firearms and to have purchased firearms during the opening months of the COVID-19 pandemic. Those intending to purchase firearms did not endorse lower perceived neighborhood safety, however, indicating that their intent to purchase firearms is unlikely to be driven by tangible threats in their immediate environment. These findings highlight that exaggerated fears may be motivating individuals to purchase firearms to diminish anxiety and that this trend may be particularly common among individuals who already own firearms.

Associations among exaggerated threat perceptions, suicidal thoughts, and suicidal behaviors in U.S. firearm owners

Firearm availability has traditionally been conceptualized as an environmental risk factor for suicide mortality. Firearm acquisition for the primary purpose of self-protection (i.e., protective gun ownership) is often motivated by exaggerated threat expectancies-a central component of anticipatory anxiety-but firearm acquisition may paradoxically reinforce or exacerbate threat expectancies and contribute to behavioral disinhibition. Firearm ownership may therefore confer increased risk for suicide mortality through biobehavioral mechanisms. The present study conducted an initial test of this hypothesis by examining associations among firearm ownership, intentions to acquire additional firearms, threat expectancies, and past-month suicidal thoughts and behaviors using data collected from a national sample of 6200 U.S. adults. Results indicated threat expectancies and rates of suicide-related behaviors were significantly elevated among protective gun owners and participants who intended to acquire a firearm within the next year as compared to non-gun owners and non-protective gun owners. Threat expectancies were associated with significantly increased risk for past-month suicide-related behavior. Results suggest that threat expectancies in particular, and anticipatory anxiety more generally, may be biobehavioral processes associated with the correlation of firearm ownership and increased suicide risk.

Evaluating the Factor Structure of the Posttraumatic Cognitions Inventory

The Posttraumatic Cognitions Inventory (PTCI) is one of the most widely used measure of posttraumatic cognitions. The original factor analysis of the PTCI provided evidence for a three-factor model of negative cognitions about self, world, and self-blame. However, subsequent research has failed to replicate this factor structure without removing multiple items. Given these inconsistent findings, we examined the PTCI factor structure in a sample of trauma-exposed undergraduates (n = 868). First, we conducted a series of four confirmatory factor analyses (CFAs) based on previously published models of the PTCI and a modified model based on previously removed items, all which indicated poor fit. Next, we conducted a CFA of the recently published three-factor PTCI-9, which approached adequate fit. We then replicated the CFA of the PTCI-9 in a second independent sample (n = 971), finding a similar pattern of near adequate fit. These findings highlight the need to revise the PTCI. In addition, results indicate the promising nature of the PTCI-9 as an alternative measure of posttraumatic cognitions.

A combined individual and group-based stabilization and skill training intervention versus treatment as usual for patients with long lasting posttraumatic reactions receiving outpatient treatment in specialized mental health care - a study protocol for a randomized controlled trial

BACKGROUND

Suffering linked to previous interpersonal trauma is common among patients in mental health care. Diagnostic labels may vary, but the clinical picture is often characterized by long-lasting and complex psychological and somatic symptoms, subjective distress and reduced quality of health and life. A substantial proportion of patients do not recover after individual treatment in ordinary specialized mental healthcare settings, despite the proven usefulness of individual trauma-specific treatments. The therapeutic factors that arise in group settings, such as normalization, shame reduction and corrective relational experiences, may be particularly useful for trauma survivors. However, evidence in support of group treatment for trauma survivors is scarce. This study aims to test whether combining a novel group intervention to individual treatment is superior to conventional individual out-patient treatment in an ordinary community mental health hospital.

METHODS

In a single-site, non-blinded, randomized controlled trial (RCT), the effect of a combined group-based stabilization and skill-training (SST) intervention added to individual treatment will be compared to conventional treatment (treatment as usual, TAU) alone. Participants (N = 160) with ongoing and long-lasting reactions related to known adverse life events from the past will be recruited among patients at general outpatient clinics in a community mental health centre at St. Olav's University Hospital, Trondheim, Norway. Following baseline assessment and randomization, participants will complete follow-up measures at 4, 8, 13 and 19 months post-baseline. The primary outcome is personal recovery (The questionnaire about the process of recovery , QPR). Secondary outcomes include (1) self-reported symptoms of posttraumatic stress, general mental and somatic health symptoms, well-being, functional impairment and client satisfaction, (2) immunological and endocrine response measured in blood samples and (3) national registry data on occupational status, use of mental health services and pharmacological treatment. Additionally, mechanisms of change via posttraumatic cognitions will be examined.

DISCUSSION

The addition of a group-based intervention to individual treatment for trauma survivors might prove to be an efficient way to meet the need of long-lasting high-intensity treatment in a large group of patients in mental health care, thereby reducing their suffering and increasing their psychosocial functioning.

The efficacy of written exposure therapy versus imaginal exposure delivered online for posttraumatic stress disorder: Design of a randomized controlled trial in Veterans

Adapting evidence-based treatments for online delivery has potential to significantly increase the reach of effective care to Veterans with posttraumatic stress disorder (PTSD). This paper describes the rationale for and methods of a randomized controlled trial comparing the efficacy and efficiency of written exposure therapy versus imaginal exposure for PTSD delivered in a novel online and variable length format. Participants will be 300 Veterans seeking treatment for clinically significant symptoms of PTSD. Participants will be randomly assigned to either written exposure or imaginal exposure via verbal recounting and will complete between 4 and 8 online therapy sessions facilitated by trained peer support specialists. Treatment is terminated before session 8 if the PTSD symptom improvement criterion is met. Assessments will be conducted at baseline, post-treatment, and at 3-month follow-up. The primary hypotheses are that written exposure therapy will be noninferior to imaginal exposure with respect to treatment efficacy and efficiency. Secondary hypotheses relate to identifying and comparing potential mediators of PTSD treatment outcome, including trauma-related cognitions and emotion regulation.
