A prospective investigation of the role of cognitive factors in persistent posttraumatic stress disorder (PTSD) after physical or sexual assault

Cultural differences in appraisals of control and posttraumatic stress disorder symptoms

Background: Appraisals are central to posttraumatic stress disorder (PTSD). Yet, few studies have examined how culture influences the associations between different types of trauma-related appraisals and PTSD symptoms.Objective: This study investigated cultural influences on appraisals of control and their associations with PTSD symptoms.Method: European Australian (n = 140, Mage = 35.80, SD = 12.44; 21 men, 97 women, 20 gender diverse/prefer not to report) and Chinese Australian (n = 129, Mage = 30.16, SD = 8.93, 21 men, 97 women, 20 gender diverse/prefer not to report) trauma survivors completed measures of appraisals, cultural values, and PTSD symptoms.Results: Findings showed that the Chinese Australian group was associated with greater Chinese cultural beliefs about adversity (i.e. emphasizing the value of adversity and people's ability to overcome adversity) and fewer fatalism appraisals (i.e. appraising one's destiny as externally determined), which in turn were atemporally associated with fewer PTSD symptoms; these atemporal indirect associations were moderated by self-construal and holistic thinking. The Chinese Australian group also reported fewer secondary control appraisals (i.e. attempts to change aspects of the self and accept current circumstances), which were atemporally associated with greater PTSD symptoms. In contrast, the European Australian group was associated with fewer primary control appraisals (i.e. perceived ability to personally change or control a situation), which were atemporally associated with greater PTSD symptoms.Conclusion: These findings highlight the importance of considering the influence of culture on appraisals in PTSD. However, it must be noted that causal relationships cannot be inferred from cross-sectional mediation analyses and thus, future longitudinal research is needed.

Sexual Assault History May Moderate Posttraumatic Cognition and Posttraumatic Stress Among Trauma-Exposed Sexual Minority Women

Sexual minority women (SMW) are highly vulnerable to trauma exposure and posttraumatic stress disorder (PTSD) symptoms following trauma exposure. Negative posttraumatic cognitions (i.e., negative cognitions about self, world, and self-blame following trauma exposure) are hypothesized to exacerbate and maintain the relationship between trauma exposure and PTSD symptoms. Posttraumatic cognitions are particularly important to examine in relation to PTSD symptoms among trauma-exposed SMW given their elevated risk for trauma exposure and PTSD. It is also important to understand whether the strength of this relationship differs as a function of trauma type to elucidate potentially differential pathways for risk by trauma type in this population. The current study explored whether trauma type (sexual assault vs. nonsexual trauma) moderated the relationship between negative posttraumatic cognitions and PTSD symptom severity among a sample of trauma-exposed SMW. Participants were SMW (n = 516) users of an online survey platform, Prolific. Data were collected via 20-minute online survey. Results indicated that trauma type moderated the relationship between negative posttraumatic cognitions and PTSD symptom severity, such that the relationship was stronger among those who had experienced at least one sexual assault in their lifetime. Results suggest that negative posttraumatic cognitions may be more strongly related to PTSD symptom severity among SMW who have experienced at least one sexual assault. Notably, this difference was in magnitude only, as the posttraumatic cognition-PTSD symptom relationship remained significant among nonsexual trauma survivors. Negative posttraumatic cognitions may be an especially relevant treatment target among SMW survivors of sexual assault.

Using experience sampling methodology (ESM) to improve our understanding of day-to-day intrusion frequency and related distress in survivors of trauma

BACKGROUND AND OBJECTIVES

Cognitive models of posttraumatic stress disorder (PTSD) suggest that appraisals of traumatic sequelae and subsequent distress drive the development and maintenance of PTSD. Posttraumatic research has relied heavily on macro-longitudinal designs, with weeks or months between assessments of trauma-related cognitions and symptoms. The present study uses experience sampling methodology (ESM) better understand the day-to-day experiences of trauma exposed individuals.

METHODS

One-hundred trauma exposed adults reported their posttraumatic symptoms, interpretations, and behaviours four times a day over a 10-day ESM period.

RESULTS

As anticipated, within-person fluctuations in negative appraisals of intrusions and maladaptive coping strategies (e.g., thought suppression) were significantly positively associated with intrusion frequency and related distress. In all cases, the associations for negative appraisals and maladaptive coping were stronger with intrusion related distress than intrusion frequency.

LIMITATIONS

The observed contemporaneous associations only demonstrate that variables reliably fluctuated together and cannot indicate causality.

CONCLUSIONS

The findings demonstrate that day-to-day fluctuations in trauma related perceptions and sequelae are significant and should be explored alongside broader individual differences to advance our understanding of the development, maintenance, and treatment of PTSD.

Effects of peritraumatic reactions on post-traumatic stress among Kahramanmaras earthquake survivors

PURPOSE

Peritraumatic reactions play a crucial role in the development of mental health problems, including depression and post-traumatic stress disorder. Therefore, this study sought to examine the influence of the peritraumatic reactions, including peritraumatic dissociation, peritraumatic distress, mental defeat, and tonic immobility, on post-traumatic stress disorder and major depressive disorder in earthquake survivors.

MATERIALS AND METHODS

A total of 261 adult participants aged between 18 and 65 (Mage=29.20, SD = 28.06, 162 were female, and 99 were male) who were exposed to the Kahramanmaras earthquake in February 2023 were recruited in the study. Data were collected between April 10 and 18 2023, two months after the earthquake. Participants completed questionnaires, including The International Trauma Questionnaire, The International Depression Questionnaire, The Mental Defeat Questionnaire, The Tonic Immobility Scale, and The Peritraumatic Dissociative Experiences Questionnaire.

RESULTS

Two-step multiple linear regression analyses indicated all peritraumatic reactions predicted both post-traumatic stress disorder and depression. Dominance analysis results showed that the contribution of peritraumatic dissociation in predicting PTSD and depression was higher among other peritraumatic reactions.

CONCLUSION

The findings of the study revealed a robust association between peritraumatic reactions and both depression and PTSD, shedding light on the underlying processes in the development of trauma-related disorders. Early assessment of peritraumatic reactions may be useful in identifying individuals at risk of developing PTSD and depression.

Mental Defeat and Suicidality in Chronic Pain: A Prospective Analysis

Living with chronic pain has been identified as a significant risk factor for suicide. Qualitative and cross-sectional studies have reported an association between mental defeat and suicidal thoughts and behavior in patients with chronic pain. In this prospective cohort study, we hypothesized that higher levels of mental defeat would be associated with increased suicide risk at a 6-month follow-up. A total of 524 patients with chronic pain completed online questionnaires measuring variables related to suicide risk, mental defeat, sociodemographic, psychological, pain, activity, and health variables. At 6 months, 70.8% (n = 371) of respondents completed the questionnaires again. Weighted univariate and multivariable regression models were run to predict suicide risk at 6 months. The clinical suicide risk cutoff was met by 38.55% of the participants at baseline and 36.66% at 6 months. Multivariable modeling revealed that mental defeat, depression, perceived stress, head pain, and active smoking status significantly increased the odds of reporting higher suicide risk, while older age reduced the odds. Receiver operating characteristic (ROC) analysis showed that assessment of mental defeat, perceived stress, and depression is effective in discriminating between 'low' and 'high' suicide risk. Awareness of the prospective links from mental defeat, depression, perceived stress, head pain, and active smoking status to increased suicide risk in patients with chronic pain may offer a novel avenue for assessment and preventative intervention. PERSPECTIVE: Results from this prospective cohort study suggest that mental defeat is a significant predictor of increased suicide risk among patients with chronic pain, along with depression, perceived stress, head pain, and active smoking status. These findings offer a novel avenue for assessment and preventative intervention before risk escalates.

Moving From Traumatic Events to Traumatic Experiences in the Study of Traumatic Psychopathology

Trauma is defined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) as an event that includes "actual or threatened death, serious injury, or sexual violence" (p. 271). The list of traumatic events included in the DSM-5 represents a long history of psychiatry and psychology's attempts to define trauma and differentiate these events from less severe stressors. In this commentary, we suggest that this strict distinction between traumatic events and stressful events is not useful for public health. The current DSM-5 list of traumatic events may work well for identifying people with the most severe experiences and highest conditional probability of distress who need clinical care. However, the public health field has different priorities. If we think about posttraumatic psychological distress on a population scale, it is not only helping those with the most severe experiences that is needed; rather, public health requires paying attention to all people experiencing distressing stress and trauma reactions. We propose that context is crucial to the development of a population-relevant definition of trauma and provide examples of situations in which stressors have resulted in posttraumatic psychological distress and in which traumatic event reactions have been mitigated by the context in which they occur. We discuss trauma context from an epidemiologic perspective and conclude with recommendations for the field. This article is part of a Special Collection on Mental Health.

Changes in cognitive processes and coping strategies precede changes in symptoms during cognitive therapy for posttraumatic stress disorder

Theories of posttraumatic stress disorder (PTSD) highlight the role of cognitive and behavioral factors in its development, maintenance, and treatment. This study investigated the relationship between changes in factors specified in Ehlers and Clark's (2000) model of PTSD and PTSD symptom change in 217 patients with PTSD who were treated with cognitive therapy for PTSD (CT-PTSD) in routine clinical care. Bivariate latent change score models (LCSM) of session-by-session changes in self-report measures showed that changes in PTSD symptoms were preceded by changes in negative appraisals, flashback characteristics of unwanted memories, safety behaviours, and unhelpful responses to intrusions, but not vice versa. For changes in trauma memory disorganization and PTSD symptoms we found a bidirectional association. This study provides evidence that cognitive and behavioral processes proposed in theoretical models of PTSD play a key role in driving symptom improvement during CT-PTSD.

The Influence of Multiple Community Level Traumatic Event Types on Mental Health Outcomes

Lebanon witnessed three large-scale negative community level events in 2020; a severe economic crisis, the COVID-19 pandemic, and an explosion in the port of the capital city, Beirut, which resulted in the deaths of 218 individuals and several thousand injured. The current study examined the relationship between the number of community level events individuals identified as personally impactful and corresponding levels of anxiety, depression, and symptoms of PTSD. The study also examined the roles of specific protective factors including perceived social support, resilience, and religious coping. A total of 406 participants aged between 18 to 64 years completed validated self-report measures online in February 2021. Results indicated elevated levels of mental health difficulties within the sample with over half of the participants reporting moderate to severe anxiety and moderate to severe depression and meeting the cut-off for probable PTSD. Females had significantly higher scores on measures of depression, anxiety, and PTSD. Individuals reporting all three events as negatively impactful were 47% more likely to meet the cut-off for PTSD than individuals identifying a single event. Resilience appeared to be the strongest protective factor against elevated scores on all three mental health outcomes. Higher scores on negative religious coping were also associated with elevated PTSD scores. Low levels of resilience, higher negative religious coping, and being a female were identified as significant predictors of reaching the PTSD cut-off using binary logistic regression analysis.

The Role of Coping Behaviors and Intoxication in Trauma Symptomology Subsequent to Sexual Victimization

College women are at an elevated risk for sexual victimization (SV) and secondary physical and psychological consequences. While some women experience negative outcomes such as posttraumatic stress disorder (PTSD), others experience reduced or complete absence of distress following SV. The variation in outcomes may be associated with the victim's level of intoxication, which may in turn affect their processing of and coping with the event. We examined the effects of SV severity on PTSD via coping and intoxication using a moderated mediation analysis among female college students (N = 375). Results demonstrate that coping mediates the association between SV severity and PTSD symptomology; however, intoxication did not moderate these associations. Results suggest that regardless of intoxication, SV severity influences various coping styles and plays an important role in a victim's adjustment post-victimization.

Exposure to continuous political violence: rational and experiential thinking styles, coping styles and post traumatic stress symptoms

Cognitive style is considered an important determinant of individual behavior. The aim of the present study was to examine the relations between rational and experiential thinking styles, coping styles and Post Traumatic Stress (PTS) symptoms among civilians exposed to continuous and ongoing exposure to political violence. Three-hundred and thirty-two Israeli adult citizens living in the south region of Israel reported on their experiences of exposure to political violence as well as level of PTS, coping styles, and preference toward rational and experiential processing style. Results showed that low rational thinking was related with elevated PTS, both directly and indirectly through the mediation of high emotion-focused coping. The findings suggest that rational thinking may serve as a protective factor against stress related to chronic exposure to political violence; conversely, a preference for low rationality may be a risk factor.

Moving forward with the loss of a loved one: treating PTSD following traumatic bereavement with cognitive therapy

Traumatic loss is associated with high rates of post-traumatic stress disorder (PTSD) and appears to inhibit the natural process of grieving, meaning that patients who develop PTSD after loss trauma are also at risk of experiencing enduring grief. Here we present how to treat PTSD arising from traumatic bereavement with cognitive therapy (CT-PTSD; Ehlers et al., 2005). The paper describes the core components of CT-PTSD for bereavement trauma with illustrative examples, and clarifies how the therapy differs from treating PTSD associated with trauma where there is no loss of a significant other. A core aim of the treatment is to help the patient to shift their focus from loss to what has not been lost, from a focus on their loved one being gone to considering how they may take their loved one forward in an abstract, meaningful way to achieve a sense of continuity in the present with what has been lost in the past. This is often achieved with imagery transformation, a significant component of the memory updating procedure in CT-PTSD for bereavement trauma. We also consider how to approach complexities, such as suicide trauma, loss of a loved one in a conflicted relationship, pregnancy loss and loss of life caused by the patient.

Key learning aims

To be able to apply Ehlers and Clark's (2000) cognitive model to PTSD arising from bereavement trauma.To recognise how the core treatment components differ for PTSD associated with traumatic bereavement than for PTSD linked to trauma where there is no loss of life.To discover how to conduct imagery transformation for the memory updating procedure in CT-PTSD for loss trauma.

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.

Women's Behavioral Coping Responses During Sexual Assault: Association With Posttraumatic Stress Disorder Symptoms and the Moderating Role of Alexithymia

We examined the associations between women's behavioral coping responses during sexual assault and posttraumatic stress disorder (PTSD) symptoms, and the moderating role of alexithymia in college women (N  =  152). Immobilized responses (b  =  0.52, p < .001), childhood SA (b  =  0.18, p  =  .01), and alexithymia (b  =  0.34, p < .001) significantly predicted PTSD. The interaction between immobilized responses and alexithymia was significant (b  =  0.39, p  =  .002), indicating a stronger association for those higher in alexithymia. Immobilized responses are associated with PTSD, particularly for those with difficulty identifying and labeling emotions.

Investigating mental defeat in individuals with chronic pain: Protocol for a longitudinal experience sampling study

INTRODUCTION

Previous qualitative and cross-sectional research has identified a strong sense of mental defeat in people with chronic pain who also experience the greatest levels of distress and disability. This study will adopt a longitudinal experience sampling design to examine the within-person link between the sense of mental defeat and distress and disability associated with chronic pain.

METHODS AND ANALYSIS

We aim to recruit 198 participants (aged 18-65 years) with chronic pain, to complete two waves of experience sampling over 1 week, 6 months apart (time 1 and time 2). During each wave of experience sampling, the participants are asked to complete three short online surveys per day, to provide in-the-moment ratings of mental defeat, pain, medication usage, physical and social activity, stress, mood, self-compassion, and attention using visual analogue scales. Sleep and physical activity will be measured using a daily diary as well as with wrist actigraphy worn continuously by participants throughout each wave. Linear mixed models and Gaussian graphical models will be fit to the data to: (1) examine the within-person, day-to-day association of mental defeat with outcomes (ie, pain, physical/social activity, medication use and sleep), (2) examine the dynamic temporal and contemporaneous networks of mental defeat with all outcomes and the hypothesised mechanisms of outcomes (ie, perceived stress, mood, attention and self-compassion).

ETHICS AND DISSEMINATION

The current protocol has been approved by the Health Research Authority and West Midlands-Solihull Research Ethics Committee (Reference Number: 17/WM0053). The study is being conducted in adherence with the Declaration of Helsinki, Warwick Standard Operating Procedures and applicable UK legislation.

Validation of the Greek Version of the State Shame and Guilt Scale (SSGS)

Both shame and guilt are self-conscious negative emotions claiming self-representations and self-awareness. Growing evidence indicates that these pessimistic emotions are associated to stress and stress-related disorders. The aim of this study was to translate and investigate the validity and reliability of the State Shame and Guilt Scale (SSGS) in a Greek adult population sample. A total of 181 adults (63% women) participated in the study. To validate the SSGS, correlations with the Depression Anxiety Stress Scales (DASS) and the Perceived Stress Scale (PSS) were also examined. Exploratory factor analysis was used to examine the factors of the Greek version of the SSGS. In addition, for greater validity, comparisons were made according to sex, marital status and level of education. The reliability assessment revealed that the index of internal consistency (Cronbach's alpha) was above the acceptable margin (0.7) for the three subscales (shame; 0.717, guilt; 0.770, pride; 0.874). The Greek version of the 15-item State Shame and Guilt Scale (SSGS) demonstrated good psychometric properties and could be proven useful for the assessment of shame, guilt, and pride.

Evaluating changes in negative posttrauma cognition as a mechanism of PTSD severity changes in two separate intensive treatment programs for veterans

BACKGROUND

A wealth of evidence has illustrated that reductions in negative posttrauma cognitions (NPCs) predict improvement in posttraumatic stress disorder (PTSD) symptoms during treatment. Yet, the specific temporal arrangement of changes in these constructs is less well understood. This study examined the temporal association between NPC changes and PTSD symptom changes in two distinct intensive PTSD treatment samples.

METHODS

Data from 502 veterans who completed a 3-week CPT-based intensive PTSD treatment program was used to test the extent to which lagged NPC measurement predicted the next occurring PTSD severity measurement using linear mixed effects regression models. PTSD severity was assessed every other day during treatment. NPCs were assessed at three treatment timepoints. A second sample of 229 veterans who completed a 2-week CPT-based intensive PTSD treatment program was used to replicate these findings.

RESULTS

Across both intensive PTSD treatment programs, NPCs generally increased from intake the end of the first treatment week, which was followed by gradual decreases in NPCs throughout the rest of both programs. Change in NPCs during both the 3-week (b = .21, p < .001, R² = .38) and the 2-week programs (b = 0.20, p < .001, R² = .24) were significant predictors of change in PTSD symptom severity. However, the reverse was true as well, with change in PTSD severity predicting latter change in NPCs during both the 3-week (b = 1.51, p < .001, R² = .37) and 2-week (b = 1.37, p < .001, R² = .33) programs, further raising questions about temporality of the association between NPCs and PTSD symptom severity during treatment.

CONCLUSIONS

The present study demonstrated that changes in NPCs may not temporally precede changes in PTSD symptom severity in PTSD treatment samples. Instead, we observed earlier PTSD symptom changes and a bidirectional association between the two constructs across both samples. Clinically, the study supports the continued focus on NPCs as an important treatment target as they are an important indicator of successful PTSD treatment, even if they may not be a direct mechanism of treatment-based changes in PTSD severity. Future research should attempt to identify alternative mechanisms of change in CPT.

Are Survivors of Sexual Assault Blamed More Than Victims of Other Crimes?

Although victim blaming in the context of sexual assault is often emphasized, little research has compared rates of victim blaming following sexual assault relative to other forms of victimization. This research investigated whether there is a crime-specific bias toward blaming victims of sexual assault. Victim blaming was assessed via different methods from the observer perspective in vignette-based studies, as well as survivors' accounts of social reactions they received. In Study 1, participants were asked to rate how much the survivor was to blame in three vignettes, each with a different randomized crime outcome: rape, physical assault, or theft. Study 2 assessed blame for a vignette that either ended in rape or theft, via a causal attribution statement. Study 3 asked interpersonal trauma survivors who had experienced at least two forms of victimization (i.e., sexual assault, physical assault, or theft) to report the social reactions they received following disclosure of each of these crimes. Across all three studies, victim blaming occurred following multiple forms of victimization and there was no evidence of a particular bias toward blaming survivors of sexual assault more so than other crimes. However, results of Study 3 highlight that, following sexual assault, survivors receive more silencing and stigmatizing reactions than they experienced after other crimes. Interpersonal traumas (i.e., sexual or physical assault) also resulted in more egocentric responses compared to theft. Altogether, there does not appear to be a crime-specific bias for victim blaming; however, crime-specific bias is apparent for some other, potentially understudied, social reactions. Implications of these findings highlight the value of victim blaming education and prevention efforts through trauma-informed services and outreach following victimization. Furthermore, service providers and advocates might especially seek to recognize and prevent silencing and stigmatizing reactions following sexual assault disclosures.

Longitudinal relationships among posttraumatic stress disorder symptom clusters in response to positive memory processing

BACKGROUND AND OBJECTIVES

Avoidance, inherent to posttraumatic stress disorder (PTSD) symptomatology, is theoretically and empirically linked to the maintenance of PTSD symptom severity. While research indicates traumatized individuals avoid positive and trauma memories, several PTSD treatments focus exclusively on traumatic memories. We examined the mediating role of PTSD's avoidance in the relationship between processing positive memories and PTSD cluster severity (intrusion, mood/cognitions, arousal).

METHODS

Sixty-five trauma-exposed college students (M_age = 22.52; 86.10% female) were randomly assigned to 3 conditions: narrating/processing, writing/processing, or control (same task across baseline [T0] and follow-up [T1]).

RESULTS

Half-longitudinal mediation models indicated participation in the narrating vs. writing and control conditions predicted decreases in T1 intrusion severity via reduction in T1 avoidance severity. Similarly, participation in the narrating vs. writing and control conditions predicted decreases in T1 mood/cognitions' severity via reduction in T1 avoidance severity. Participation in the narrating vs. writing condition predicted decreases in T1 arousal severity via reduction in T1 avoidance severity.

LIMITATIONS

Data was obtained from an analogue small-size sample of university students. In addition, sessions were only 6-8 days apart, with the processing component of each session lasting ∼30 min.

CONCLUSIONS

Processing positive memories may relate to lower PTSD severity via a reduction in PTSD's avoidance, paralleling effects of processing trauma memories. Our findings support future investigations of the mechanisms underlying impacts of positive memory processing in the context of PTSD treatments.

A predictive coding account of value-based learning in PTSD: Implications for precision treatments

While there are a number of recommended first-line interventions for posttraumatic stress disorder (PTSD), treatment efficacy has been less than ideal. Generally, PTSD treatment models explain symptom manifestation via associative learning, treating the individual as a passive organism - acted upon - rather than self as agent. At their core, predictive coding (PC) models introduce the fundamental role of self-conceptualisation and hierarchical processing of one's sensory context in safety learning. This theoretical article outlines how predictive coding models of emotion offer a parsimonious framework to explain PTSD treatment response within a value-based decision-making framework. Our model integrates the predictive coding elements of the perceived: self, world and self-in the world and how they impact upon one or more discrete stages of value-based decision-making: (1) mental representation; (2) emotional valuation; (3) action selection and (4) outcome valuation. We discuss treatment and research implications stemming from our hypotheses.

For there is nothing either good or bad: a study of the mediating effect of interpretation bias on the association between mindfulness and reduced post-traumatic stress vulnerability

BACKGROUND

Despite increasing interest in the association between mindfulness and reduced trauma vulnerability, and the use of mindfulness in the latest interventions for Post-Traumatic Stress Disorder (PTSD), few studies have examined the mechanisms through which mindfulness may influence post-trauma psychopathology. The present study aimed to determine whether negative interpretation bias, the tendency to interpret ambiguous information as negative or threatening rather than positive or safe, mediates the association between higher levels of trait mindfulness and lower levels of PTSD symptoms. Negative interpretation bias was examined due to prior evidence indicating it is associated with being less mindful and post trauma psychopathology.

METHODS

The study examined 133 undergraduate students who reported exposure to one or more potentially traumatic events in their lifetime. Participants completed self-report measures of trait mindfulness (Five Facet Mindfulness Questionnaire - Short Form; FFMQ-SF) and PTSD symptoms (Post-Traumatic Stress Disorder Checklist - Civilian version; PCL-C) as well an interpretation bias task that assessed the degree to which participants interpreted a range of everyday hypothetical scenarios to be threatening to their physical and/or psychological wellbeing.

RESULTS

Results of a mediation analysis indicated a significant negative direct effect of trait mindfulness on PTSD symptomatology (p < .001). There was no evidence that negative interpretation bias mediated this relationship [BCa CI [-0.04, 0.03)], nor was it associated with trait mindfulness (p = .90) and PTSD symptomatology (p = .37).

CONCLUSIONS

The results of the current study provide further evidence of the link between trait mindfulness and reduced post-trauma psychopathology while providing no support for the role of negative interpretation bias in this relationship.

The boundaries between complex posttraumatic stress disorder symptom clusters and post-migration living difficulties in traumatised Afghan refugees: a network analysis

BACKGROUND

Psychological distress due to the ongoing war, violence, and persecution is particularly common among Afghan asylum seekers and refugees. In addition, individuals face a variety of post-migration living difficulties (PMLDs). Complex posttraumatic stress symptoms are among the most common mental health problems in this population, and were associated with the overall burden of PMLDs. The complex interplay of posttraumatic symptoms has been investigated from a network perspective in previous studies. However, individuals are embedded in and constantly react to the environment, which makes it important to include external factors in network models to better understand the etiology and maintaining factors of posttraumatic mental health problems. PMLDs are a major risk factor for posttraumatic distress and considering their impact in interventions might improve response rates. However, the interaction of these external factors with posttraumatic psychopathological distress is not yet fully understood. Thus, we aimed to illuminate the complex interaction between PMLDs and CPTSD symptom clusters.

OBJECTIVE

The main objective is the exploration of the network structure and the complex interplay of ICD-11 CPTSD symptom clusters and distinct forms of PMLDs.

METHOD

The symptom clusters of CPTSD and PMLDs were collected within a randomised controlled trial among 93 treatment-seeking Afghan asylum seekers and refugees via a fully structured face-to-face and interpreter assisted interview. Using a network analytical approach, we explored the complex associations and network centrality of the CPTSD symptom clusters and the PMLD factors: discrimination & socio-economical living conditions, language acquisition & barriers, family concerns, and residence insecurity.

RESULTS

The results suggest direct links within and between the constructs (CPTSD, PMLD). Almost all PMLD factors were interrelated and associated to CPTSD, family concerns was the only isolated variable. The CPTSD symptom cluster re-experiencing and the PMLD factor language acquisition & barriers connected the two constructs. Affective dysregulation had the highest and avoidance the lowest centrality.

CONCLUSIONS

Re-experiencing and affective dysregulation have the strongest ties to PMLDs. Thus, these domains might explain the strong association of posttraumatic psychopathology with PLMDs and, consequently, prioritization of these domains in treatment approaches might both facilitate treatment response and reduce burden caused by PMLDs.

Acting with awareness moderates the association between lifetime exposure to interpersonal traumatic events and craving via trauma symptoms: a moderated indirect effects model

BACKGROUND

History of exposure to traumatic events (ETE) is common among women in substance use disorder (SUD) treatment and is related to craving. We examined whether ETE (i.e., emotional, physical, sexual abuse) in childhood, adulthood, or both is related to craving via trauma symptoms and how trait mindfulness might attenuate this association.

METHODS

Baseline data from a larger randomized clinical trial of a mindfulness-based intervention for women (N = 245) in SUD treatment were used. Inclusion criteria were: 18-65 years of age, SUD diagnosis, English fluency, no cognitive impairment, and willingness to be audio recorded and provide consent. Demographics and validated measures of ETE, posttraumatic stress symptoms, trait mindfulness, and substance use craving were collected via in-person interviews. Descriptive statistics, correlational analysis, and relative direct, indirect, and conditional indirect effects models were run.

RESULTS

Most participants identified as Hispanic (58.5%), had at least a high school education (52.2%), with a mean age of 32.2. Women reported ETE in childhood only (20.4%), adulthood only (17.5%), both childhood and adulthood (50.0%), and never (11.4%). Compared to women with ETE in both childhood and adulthood, those with exposure in adulthood only (β = -.10, 95% CI = -.20, -.02) or no exposure (β = -.11, 95% CI = -.23, -.03; [∆R2= .347, F(8, 245) = 15.7, p < .001) had lower craving via lower trauma symptomatology but no difference when compared to those with ETE only in childhood. Acting with awareness moderated this indirect effect (∆R2 = .04, F(3, 245) = 4.66, p = .004. At low levels of awareness, women with ETE during both childhood and adulthood reported higher craving via trauma symptomatology than women with no exposure or only adulthood exposure.

CONCLUSIONS

Low levels of acting with awareness may worsen trauma symptoms after ETE, which in turn may lead to more craving for women in substance use treatment. Despite a small moderating effect size, acting with awareness may have clinical significance due to the prevalence of trauma symptoms among women in SUD treatment.

Cognitive Coping Reduces Posttraumatic Stress Symptoms, Especially in the Context of Self-Blame

Following a traumatic event, coping strategies may affect the natural course of posttraumatic stress symptoms (PTSS). In particular, cognitive coping strategies (how one thinks about stressors) may reduce PTSS by increasing individuals' perceived control over events, appraising them as less threatening, particularly for individuals who experience self-blame after trauma. Individuals who experience a traumatic event (n =344) completed assessments at baseline (T1), one month (T2), and two months (T3). We tested whether T1 cognitive coping strategies (positive reinterpretation, acceptance, religious coping) predicted reduced T3 PTSS and whether this reduction was mediated by increased perceived control at T2. We tested whether this effect was particularly strong for individuals experiencing self-blame. Positive reinterpretation predicted decreases in, religious coping predicted increases in, and acceptance had no direct effect on PTSS. Overall, acceptance showed the greatest potential for reducing PTSS through increased perceived control over one's life. In a fully moderated mediation model, positive reinterpretation significantly interacted and acceptance marginally interacted with self-blame to predict increased perceived control and, subsequently, decreased T3 PTSS. Specifically, acceptance and positive reinterpretation were most helpful for those with higher levels of self-blame. Religious coping interacted with self-blame to predict decreased perceived control and subsequent increased PTSS. For trauma survivors experiencing self-blame, cognitive coping strategies that utilize compassionate self-talk, such as positive reinterpretation and acceptance, may be particularly helpful at increasing perceived control after trauma, while religious coping may have deleterious effects.

Is It Personal? The Effect of Personal vs. Occupational Trauma on PTSD Symptom Severity in Emergency Responders

Emergency responders are exposed to potentially traumatic events in their line of work and as such, are at increased risk of developing post-traumatic stress disorder (PTSD). Little is known about the characteristics of trauma associated with PTSD symptoms in this population. This study analyzed the self-reported worst traumatic event on the PTSD checklist for DSM-5 for a sample of N = 610 emergency responders, working as police officers, paramedics, firefighters or search and rescue personnel. Sufficient information was available to code 98% (N = 603) participants' trauma; 84% (N = 509) met DSM-V criterion A trauma. Of the participants reporting criterion A trauma, 56.9% (N = 290) participants reported being most affected by a traumatic event that occurred in their personal lives, 41.5% (N = 211) participants reported being most affected by a work-related traumatic event and 1.6% (N = 8) reported criterion A events that were work-related and had occurred prior to their role as an emergency responder (e.g., combat). Paramedics were significantly more likely to report occupational trauma as their worst event whereas police officers, firefighters, and search and rescue workers reported personal trauma as their worst event. Personal trauma was associated with significantly greater PTSD symptom severity than occupational trauma. Emergency responders identifying as women were significantly more likely to report personal than work-related trauma as their index event and men were more likely to report work-related than personal trauma as being linked to their PTSD symptoms. The results underscore the need to consider the broader context of trauma in the emergence of PTSD symptoms in emergency workers.

A network analysis of two conceptual approaches to the etiology of PTSD

Two prominent conceptual models of posttraumatic stress disorder (PTSD) are the cognitive model, associated with cognitive processing therapy (CPT; Resick & Schnicke, 1992), and the functional contextualist model, underlying acceptance and commitment therapy (ACT; Hayes et al., 1999). Network analysis was used to examine dynamic interactions among cognitive (relating to CPT) and functional contextualistic (relating to ACT) variables and PTSD symptoms in a sample of 722 trauma-exposed adults. Results from the cognitive networks highlighted the importance of maladaptive beliefs about threat in maintaining the co-occurrence of PTSD symptoms and cognitive variables. Additionally, PTSD symptoms were more likely to lead to cognitive variables, rather than the reverse direction. Results from the functional contextualist networks identified numerous associations amongst variables that contribute to the co-occurrence of PTSD symptoms and psychological inflexibility. Findings from this study may help generate causal hypotheses that can be tested further using a longitudinal study design.

Silent and Lethal: Consequences of Sexual Violence Against Married Women in Ghana

Extant research, mostly in western countries, confirms the consequences of sexual violence against women, but academic scholarship on this topic remains scant for Ghana. This study built on existing research by exploring the consequences of sexual violence against married women in the Eastern Region of Ghana. Data were obtained from in-depth interviews purposely conducted with 15 survivors of sexual violence. The thematic analysis showed that sexual violence was accompanied by physical and emotional abuse. Following sexual violence and abuse, these women experienced physical injuries, psychological problems, sexual and reproductive health problems, and suicidal ideations. These health difficulties significantly undermined their economic activities and depleted their income. Sexual violence clearly affects women's empowerment; campaigns against gender-based violence should make sexual violence a top priority in Ghana and elsewhere.

Using Social Support Matter in the Association of Post-Traumatic Cognitions and Perceived Social Support? Comparison of Female Survivors of Intimate Partner Violence With and Without a History of Child Abuse

The association between high levels of post-traumatic stress disorder (PTSD) symptoms and low levels of perceived social support is well-documented in the trauma literature; research on processes that may underlie this association is less common. The current study examined negative attitudes about using social support as a potential link between negative post-traumatic cognitions about the world and self, one aspect of PTSD, and perceived social support in two groups of female survivors of intimate partner violence: those who had a history of child abuse (n = 153; IPV/CA+) and those who did not (n = 96; IPV/CA-). Negative attitudes about using social support were found to be an important link between negative post-traumatic cognitions and social support for both groups. IPV survivors with a history of child abuse had higher levels of negative post-traumatic cognitions about the world (d = .32) and self (d = .33), greater negative attitudes about using social support (d = .35), and lower perceived social support from family (d = .48), compared with IPV survivors without a history of child abuse. These results support the relevance of negative attitudes about using social support as one important factor in the relationship between PTSD symptoms and social support in interpersonal trauma survivors and highlight the impact that negative attitudes about using social support can have on the trauma survivor's functioning.

Prevalence and Factor Structure of PTSD in DSM-5 Versus DSM-IV in a National Sample of Sexual Minority Women

The impact of changes to posttraumatic stress disorder (PTSD) diagnostic criteria from Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) to Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) within diverse communities is unclear. Young adult sexual minority women are at high risk for interpersonal violence and other forms of trauma exposure compared with heterosexual populations and sexual minority men. They are also at heightened risk of PTSD. As a result, young adult sexual minority women are a key population of interest when examining the impact of diagnostic criteria changes. The goal of the current study was to evaluate the impact of changes to PTSD diagnostic criteria in sexual minority women. Using an online survey, we administered both the original PTSD Symptom Checklist-S (based on DSM-IV criteria) and a version adapted to assess DSM-5 criteria to a national, nonclinical sample of young adult sexual minority women (N = 767). The DSM-5 symptom criteria fit the data well in confirmatory factor analysis. Current PTSD prevalence was higher under the DSM-5 diagnostic algorithm compared with DSM-IV (18.6% vs. 22.9%; d = 0.15). Compared with DSM-IV, associations between PTSD and depression were stronger using DSM-5 criteria, whereas associations between PTSD and high-risk drinking were reduced. Findings suggest that changes to PTSD diagnostic criteria do not have a major impact on prevalence of PTSD among sexual minority women but may have some impact on observed comorbidities.

Caught by Connections: The Mediating Roles of Social and Community Support after Interpersonal Violence

The purpose of the present study was to examine the potential mediating roles of different sources of social support and sense of community on the relationship between interpersonal violence and mental health outcomes, negative posttraumatic cognitions, and posttraumatic growth. Participants (n = 459) completed an online survey. Interpersonal violence had a significant, direct effect on all posttraumatic outcomes. Support from significant others mediated the relationship between interpersonal violence and posttraumatic stress. Both support from family and a negative sense of community mediated the relationship between interpersonal violence and posttraumatic cognitions, while social support from friends and family and a positive sense of community mediated the relationship between interpersonal violence and posttraumatic growth. The results suggest that posttraumatic distress and growth may be impacted by different connection sources.

Shame, guilt, and posttraumatic stress symptoms: A three-level meta-analysis

Existing empirical findings are inconsistent on the correlations of shame and guilt with posttraumatic stress symptoms (PTSS). This study aimed to quantitatively summarize the strength of the associations of shame and guilt with PTSS and explore potential moderators. Based on a three-level meta-analytic method, shame was positively correlated with PTSS, no matter whether the effects of guilt were controlled; guilt also had a positive correlation with PTSS, regardless of whether the effects of shame were partialling out. Moderator analyses showed that type of shame measure (generalized vs. contextual vs. trauma-specific shame) moderated the relation between shame and PTSS, and type of guilt measure (generalized vs. contextual vs. trauma-specific guilt) moderated the relation between guilt and PTSS. In addition, culture had a marginally significant moderating effect on the relation between guilt and PTSS, with a stronger association of guilt with PTSS in Western culture than in Eastern culture. These results supported the links of shame and guilt to PTSS and implied that we should focus on the conceptual underpinnings of the manifest psychometric issue and maintain cultural sensitivity in future research. The implications for posttraumatic stress disorder treatment were also discussed.

Validation and Construct Validity of the Posttraumatic Avoidance Behaviour Questionnaire in a Sample of Trauma-Exposed Black Women

Engaging in posttraumatic avoidance behaviors after a traumatic incident is associated with posttraumatic stress disorder (PTSD) outcomes. Given the inherent limitations in the scope of the two-item assessment of posttraumatic avoidance used in commonly administered measures of PTSD symptoms, the 25-item Posttraumatic Avoidance Behaviour Questionnaire (PABQ) was developed to assess a range of avoidance behaviors, including avoidance of visual and sensory reminders, trauma-related thoughts, and agoraphobia, as well as avoidance related to the home, sleep, and social interaction. However, the PABQ's utility is limited by its lack of (a) construct validity and (b) validation in diverse samples. To address these limitations, we examined the psychometric properties of PABQ scores in a sample of trauma-exposed Black women (N = 601, M age = 41 years). Confirmatory factor analyses indicated that the original seven-factor model fit the data well when Item 8 was excluded, χ² (231, N = 602) = 497.86, RMSEA = .04, 90% CI [.04, .05], CFI = .99, TLI = .989, WRMR = .939, but reliability estimates were variable (i.e., Cronbach's αs = .70-.91). In addition, we found support for convergent validity, clinical validity, and incremental validity. These results provide evidence for the psychometric strengths of the PABQ in minority samples and suggest that it is a valid assessment of posttraumatic avoidance in Black women.

Prolonged grief and posttraumatic stress disorder following the loss of a significant other: An investigation of cognitive and behavioural differences

BACKGROUND

Cognitive behavioural correlates to bereavement-related mental health problems such a Prolonged Grief Disorder (PGD) and Posttraumatic Stress Disorder (PTSD) are of theoretical and clinical importance.

METHODS

Individuals bereaved at least six months (N = 647) completed measures of loss-related cognitions and behaviours (i.e., loss-related memory characteristics, negative appraisals, coping strategies, grief resilience, and perceived social disconnection) and measures of PGD and PTSD symptoms. Individuals were assigned to one of four groups depending on probable clinical diagnoses (No-PGD/PTSD, PTSD, PGD, PGD+PTSD).

RESULTS

Results indicated that higher loss-related memory characteristics and lower grief resilience increased the likelihood of a clinical problem. The PGD and PGD+PTSD groups reported significantly higher loss-related memory characteristics and appraisals compared to the PTSD group. Social disconnection increased the likelihood of comorbid PGD+PTSD in comparison to any other group.

CONCLUSIONS

Results indicate cognitive differences between loss-related cognitions, memory characteristics and coping strategies between PGD and PTSD, and points to distinct cognitive correlates to psychopathology following loss.

An exploratory investigation into the effects of mental defeat on pain threshold, pain rating, pain anticipation, and mood

In chronic pain, mental defeat is considered as a disabling type of self-evaluation triggered by repeated episodes of debilitating pain. This exploratory study experimentally tested the effect of an activated sense of defeat, as well as its interaction with pain catastrophizing, on pain and mood. Participants (N = 71) were allocated to either high or low pain catastrophizing groups and then randomly assigned to receive either defeat or neutral manipulations. A cold pressor task administered before and after the thought manipulation measured pain threshold, alongside visual analogue scales for mental defeat, attention, pain intensity, pain anticipation as well as mood. Thought manipulation checks supported successful defeat activation. Defeat activation was associated with increased negative mood and attentional disengagement from the nociceptive stimuli, irrespective of pain catastrophizing tendency. There were no changes in pain threshold, pain or pain anticipation ratings. The results suggest that mental defeat can be experimentally activated using an autobiographical memory task and that an activated sense of defeat appears to operate independently from pain catastrophizing in influencing mood and attentional disengagement from the nociceptive stimuli. Future research can utilize our experimental approach to evaluate the effect of an activated sense of mental defeat in people with chronic pain, for whom the magnitude of pain, mood and attentional responses may be stronger and broader.

Navigating the who, where, what, when, how and why of trauma exposure and response

Individual differences in the response to trauma are influenced by numerous contextual factors such as one's cultural background, the environment in which trauma occurs, the meanings attached to traumatic experiences, and various other social and cultural determinants both before and after traumatic exposure. This special issue of the European Journal of Psychotraumatology presents a series of papers conducted as part of the Collaborative Network for Training and Excellence in Psychotraumatology (CONTEXT); a programme of research which seeks to advance our understanding of the impact of trauma within diverse populations who are highly trauma exposed. Applying a context-specific focus, CONTEXT prioritised working closely with service users and those organisations delivering critical support in the wake of trauma exposure. The seven papers presented in this special issue are divided into those who are exposed to trauma either: (i) directly (survivors of childhood adversity in the USA; LGB youth in Northern Ireland; refugees and asylum seekers in the EU; and members of the general population exposed to conflict in Israel) or (ii) vicariously (fire fighters in the UK, humanitarian aid volunteers in Sudan, and child protection workers in Denmark). Together, findings from these studies demonstrate that social support, in its many different forms, is a universally important factor in the response to trauma. We discuss how traumatic stress can be compounded when, and can thrive within, contexts where necessary social support is absent or inadequate. We also emphasize the importance of recognizing the context specificity of trauma exposure and trauma response, as well as the need for collaboration between psychotrauma researchers and organisations who deliver support to traumatized populations to ensure rapid and effective translation of research findings into practice.

A critical review of mechanisms of adaptation to trauma: Implications for early interventions for posttraumatic stress disorder

Although many attempts have been made to limit development of posttraumatic stress disorder (PTSD) by early intervention after trauma exposure, these attempts have achieved only modest success. This review critiques the biological and cognitive strategies used for early intervention and outlines the extent to which they have prevented PTSD. The major predictors of PTSD are reviewed, with an emphasis on potential mechanisms that may underpin the transition from acute stress reaction to development of PTSD. This review highlights that there is a wide range of biological and cognitive factors that have been shown to predict PTSD. Despite this, the major attempts at early intervention have focused on strategies that attempt to augment extinction processes or alter appraisals in the acute period. The documented predictors of PTSD indicate that a broader range of potential strategies could be explored to limit PTSD. The evidence that people follow different trajectories of stress response following trauma and there is a wide array of acute predictors of PTSD indicates that a flexible and tailored approach needs to be investigated to evaluate more effective early intervention strategies.

Feelings, Thoughts, and Behaviors During Disaster

Thoughts, feelings, and behaviors during traumatic events, that is, peritraumatic reactions, are key to post-trauma psychopathology development. Qualitative research is required to investigate whether existing quantitative methods capture the range and complexity of peritraumatic reactions as described by survivors. Semi-structured interviews were conducted with 104 earthquake survivors. Participants reported experiencing various peritraumatic reactions (M = 21, range = 6-43). The survivors' accounts confirmed presence and overall phenomenological characteristics of commonly studied peritraumatic reactions such as dissociation, distress, mental defeat, and immobility. In addition, novel and understudied reactions were identified: cognitive overload, hyperfocus, and emotion regulation, as well as positive affect. Finally, a number of cross-cutting phenomena were identified such as the social nature of many reactions and survivors evaluating their reactions as difficult to put into words. These findings have implications for the conceptualization of peritraumatic reactions, for trauma-focused psychotherapeutic interventions, and for the wellbeing of disaster survivors.

A longitudinal study of cognitive predictors of (complex) post-traumatic stress in young people in out-of-home care

BACKGROUND

Young people in out-of-home care are substantially more likely to meet criteria for PTSD than their peers, while their early maltreatment exposure may also place them at greater risk of developing the newly proposed complex PTSD. Yet, there remains limited empirical evidence for the mechanisms that might drive either PTSD or complex features in this group, and ongoing debate about the suitability of existing cognitive behavioural models and their related NICE-recommended treatments. In a prospective study of young people in out-of-home care, we sought to identify demographic and cognitive processes that may contribute to the maintenance of both PTSD symptom and complex features.

METHODS

We assessed 120 10- to 18-year-olds in out-of-home care and their primary carer at two assessments: an initial assessment and 12-month follow-up. Participants completed questionnaires on trauma history, PTSD symptoms and complex features, while young people only also self-reported on trauma-related (a) maladaptive appraisals, (b) memory quality and (c) coping. Social workers reported on maltreatment severity.

RESULTS

Young people's maltreatment severity was not a robust predictor of either PTSD symptoms or complex features. All three cognitive processes were moderately-to-strongly correlated with baseline and 12-month PTSD symptoms and complex features, with maladaptive appraisals the most robust unique driver of both, even when controlling for initial PTSD symptom severity.

CONCLUSIONS

Existing cognitive models of PTSD are applicable in this more complex sample of young people. The model was also found to be applicable to the additional features of complex PTSD, with the same processes driving both outcomes at both time points. Clinical implications are discussed.

Beliefs about Memory Questionnaire: psychometric properties in a natural disaster sample

Several theories exist regarding the role of memory in the development of PTSD. The metacognitive model of PTSD contends beliefs about trauma memory are pivotal in the development and maintenance of PTSD. The Beliefs About Memory Questionnaire (BAMQ) was developed to measure metacognitive beliefs about trauma memory. This study aimed to test the psychometric properties of the BAMQ and its relationship to PTSD in a community sample of 674 adults exposed to the 2010-2011 Canterbury earthquakes and Queensland floods. Participants completed a series of online, self-report questionnaires between October and December 2012, exploring thinking and memory processes related to their experience of a natural disaster. Factor analysis validated the two-factor, positive and negative structure of the BAMQ. Convergent, concurrent, and discriminant validity was established through positive relationships with relevant metacognitive beliefs, thought control variables, and risk factors related to PTSD. Logistic regression revealed scores on the BAMQ predicted clinically significant symptoms of PTSD. The psychometric properties of the BAMQ suggest the instrument is a valuable addition to the assessment of metacognitive beliefs about trauma memory, and the utility of the BAMQ in the prediction of clinically significant symptoms of PTSD.

Posttraumatic stress disorder symptom clusters, suicidal ideation, and social support in a clinical adolescent sample

Posttraumatic stress disorder (PTSD) is a risk factor for adolescent suicidal ideation (SI). This study explored the relation between PTSD symptom clusters and SI, and whether social support moderates this association, in a cross-sectional, adolescent, clinical sample (N = 125). We hypothesized that each cluster would be positively associated with SI severity and that social support would buffer these associations. Only the persistent avoidance cluster was significantly associated with SI severity. Further, social support moderated this association. Results highlight the positive association between persistent avoidance symptoms of PTSD and SI and suggest that bolstering social support serves a protective function.

Cognitive paths from trauma to posttraumatic stress disorder: a prospective study of Ehlers and Clark's model in survivors of assaults or road traffic collisions

BACKGROUND

Individual differences in cognitive responses to trauma may represent modifiable risk factors that could allow early identification, targeted early treatment and possibly prevention of chronic posttraumatic stress disorder (PTSD). Ehlers and Clark's cognitive model of PTSD suggests that negative appraisals, disjointed trauma memories, and unhelpful coping strategies maintain PTSD. These are thought to be influenced by cognitive processing during trauma. The aim of this study was to test this model prospectively with path analyses.

METHODS

Participants (N = 828) were recruited from an emergency department following injury in a violent assault or road traffic collision and 700 participated in the 6-month assessments. Cognitive processing was assessed shortly after the event, negative appraisals, disjointed memories, and unhelpful coping strategies at 1 month, persistent PTSD symptom severity at 6 months, and early PTSD symptom severity at 2 weeks.

RESULTS

Cognitive variables, with trauma type and gender, explained 52% of the variance in PTSD symptom severity at 6 months. Including early symptom severity in the model did not explain more variance (53%). Early PTSD symptom severity, with trauma type and gender, only predicted 40%. Negative appraisals and disjointed memories predicted persistent symptom severity both directly and indirectly via unhelpful strategies. Peritraumatic processing predicted persistent symptom severity mainly indirectly. The effects of trauma type and gender were fully mediated by the cognitive factors.

CONCLUSIONS

The results are consistent with theoretically derived predictions and support cognitive factors as indicators of risk for chronic PTSD and as a target for the treatment and prevention of PTSD.

The Sequential Relation Between Changes in Catastrophizing and Changes in Posttraumatic Stress Disorder Symptom Severity

Catastrophizing has been discussed as a cognitive precursor to the emergence of posttraumatic stress disorder (PTSD) symptoms following the experience of stressful events. Implicit in cognitive models of PTSD is that treatment-related reductions in catastrophizing should yield reductions in PTSD symptoms. The tenability of this prediction has yet to be tested. The present study investigated the sequential relation between changes in a specific form of catastrophizing-symptom catastrophizing-and changes in PTSD symptom severity in a sample of 73 work-disabled individuals enrolled in a 10-week behavioral activation intervention. Measures of symptom catastrophizing and PTSD symptom severity were completed at pre-, mid-, and posttreatment assessment points. Cross-sectional analyses of pretreatment data revealed that symptom catastrophizing accounted for significant variance in PTSD symptom severity, β = .40, p < .001, sr = .28 (medium effect size), even when controlling for known correlates of symptom catastrophizing, such as pain and depression. Significant reductions in symptom catastrophizing and PTSD symptoms were observed during treatment, with large effect sizes, ds = 1.42 and 0.94, respectively, ps < .001. Cross-lagged analyses revealed that early change in symptom catastrophizing predicted later change in PTSD symptoms; early changes in PTSD symptom severity did not predict later change in symptom catastrophizing. These findings are consistent with the conceptual models that posit a causal relation between catastrophizing and PTSD symptom severity. The clinical implications of the findings are discussed.

Threat appraisals, neuroticism, and intrusive memories: a robust mediational approach with replication

Background: The appraisal of a stressor substantially influences how we adapt to it. We used an experimental paradigm to test and replicate the effects of threat appraisals on subsequent intrusive memories, as well as their moderation by neuroticism. Method: In three studies (total N = 562), participants were randomly assigned to an aversive or control video and then asked to report their threat appraisals of the video. Intrusive memories were assessed at one, three, five, and seven days. We used a robust framework for testing causal mediational effects and their magnitude, including sensitivity analyses and new effect size metrics. Results: We found that threat appraisals mediated the effect of the video on intrusive memories (studies 1-3), and for people higher in neuroticism, the causal mediational pathway was stronger (study 1 and 2). Conclusions: These findings provide methodologically strong evidence that threat appraisals have causal effects on subsequent intrusive memories and that neuroticism enhances this effect, lending empirical support to appraisal theories of posttraumatic stress disorder.

Mapping the needs and psychological outcomes of Slovenian adolescent and young adult cancer patients: An exploratory mixed-method study

OBJECTIVE

With improving survival rates, it is becoming increasingly important to understand the psychological aspect and needs of young cancer patients and survivors. Our goal was to describe the self-reported levels of psychological distress, subjective illness experience and needs of young Slovenian cancer patients and survivors.

METHODS

Seventy-nine participants, aged 19-39 years, answered questionnaires about anxiety, depression, mental defeat, cancer worry and their experience of learning the diagnosis and being treated. We used visualisations to demonstrate the relationship between anxiety and depression. The qualitative responses were summarised using a content analysis approach.

RESULTS

Twenty-eight (35%) participants scored in the clinical range for anxiety and fifteen (19%) for depression. Cancer-related worry was common (85% reported at least one worry). Mental defeat was positively associated with measures of psychological distress. Those who felt negative about learning their diagnosis emphasised the need for more time, empathy and dignity. Psychological support during illness was seen as crucial.

CONCLUSION

Anxiety and depression remain a problem for a subset of patients. Medical professionals working with young people with cancer should encourage a warm atmosphere as they attend to patients' needs and concerns.

Cumulative Trauma and Adjustment in Women Exposed to a Campus Shooting: Examining the Role of Appraisals and Social Support

Experiencing repeated trauma can have increasingly detrimental effects on psychosocial functioning after subsequent stressors. These effects may be intensified for victims of interpersonal traumas given that these events are often associated with heightened risk for adverse outcomes. To better understand this relationship, the present study prospectively examined the effect of pre-shooting trauma exposure (i.e., interpersonal vs. non-interpersonal trauma) on psychological functioning (i.e., posttraumatic stress symptoms, depression) following a mass campus shooting. Based on previous research, it was expected that negative appraisals and social support would mediate this relationship. A sample of 515 college women reporting prior trauma exposure was assessed at four time points following the shooting (i.e., pre-shooting, 1-month, 6-months, and 12-months post-shooting). Bootstrap analyses with bias-corrected confidence intervals were conducted. Contrary to expectation, pre-shooting trauma exposure was unrelated to 12-month post-shooting outcomes and neither negative appraisals nor social support at 6-months post-shooting emerged as mediators. Interestingly, a history of non-interpersonal trauma was associated with greater post-shooting family and friend support than a history of interpersonal trauma. Ad hoc analyses showed that pre-shooting symptom severity and level of exposure to the shooting had indirect effects on post-shooting outcomes via post-shooting negative appraisals. These findings support that cumulative trauma, regardless of type, may not have an additive effect unless individuals develop clinically significant symptoms following previous trauma. Trauma severity also appears to play a meaningful role.

Trauma-related cognitions predict treatment response in smokers with PTSD: Evidence from cross-lagged panel analyses

OBJECTIVE

Compared to smokers without posttraumatic stress disorders (PTSD), smokers with PTSD smoke more heavily and are less successful in quitting smoking. However, limited research has examined the cognitive pathways underlying this heightened comorbidity. The current study is the first to simultaneously model the cross-sectional and lagged relationships between trauma-related cognitions and cigarette smoking, as well as between trauma-related cognitions and PTSD severity, in smokers with comorbid PTSD receiving treatment.

METHOD

Participants (n = 142) were seeking treatment for smoking cessation and PTSD as part of a randomized controlled trial of varenicline and smoking cessation counseling with or without adjunctive Prolonged Exposure (varenicline + PE vs. varenicline only) (Foa et al., 2017). Data were available for both baseline and end-of-treatment assessments of trauma cognitions severity of cigarette smoking and PTSD symptoms. We conducted both cross-sectional and lagged analysis to simultaneously examine the bidirectional relationship from trauma cognitions and 1) cigarette smoking and 2) PTSD symptoms.

RESULTS

Trauma cognitions (specifically, negative beliefs about the self and the world) were significantly associated with cigarette/day at the end of treatment for participants who received varenicline only. However, baseline trauma cognitions did not predict post-treatment cigarettes/day. Baseline trauma cognitions (specifically negative beliefs about the self and world) were associated with PTSD severity at both baseline and end of treatment; furthermore, these negative cognitions at baseline positively and prospectively predicted end-of-treatment PTSD severity, but not vice versa. Wald tests revealed that there were no treatment effects on these cross-lagged relationships. Conclusions These findings provide novel empirical support for the importance of addressing trauma-related cognitions in the smoking cessation treatment efforts for patients with comorbid PTSD and cigarette smoking.
