Predicting PTSD and Depression following Sexual Assault: The Role of Perceived Life Threat, Post-Traumatic Cognitions, Victim-Perpetrator Relationship, and Social Support

ABSTRACT Survivors of sexual assault have a high risk for posttraumatic stress disorder (PTSD), but experiencing a sexual assault alone is not sufficient for the development of the disorder. This study examined the impact of other risk factors, including the impact of victim-perpetrator relationship context (i.e. trust, importance, and closeness), perceived life threat, perceived betrayal, posttraumatic cognitions, and trauma-related social support on PTSD and depression symptoms. One hundred twenty-seven female undergraduates who self-identified as “having an uncomfortable, negative, or unwanted sexual experience” completed multiple self-report measures. Victim-perpetrator relationship variables were not associated with PTSD or depressive symptoms. Perceived life threat, perceived betrayal, and posttraumatic cognitions were all related to PTSD symptom severity. However, results from hierarchical multiple regressions indicated that when perceived life threat and posttraumatic cognitions were included in the model, perceived betrayal no longer predicted PTSD symptoms. Implications for understanding the role of posttraumatic cognitions in PTSD and depression symptoms are discussed.

Online-group intervention after suicide bereavement through the use of webinars: study protocol for a randomized controlled trial

IntroductionThe death of a significant person through suicide is a very difficult experience and can have long-term impact on an individual’s psychosocial and physical functioning. However, there are only few studies that have examined the effects of interventions in suicide survivors. In the present study, we examine an online-group intervention for people bereaved by suicide using a group-webinar.MethodsThe intervention was developed based on focus groups with the target group. The cognitive-behavioral 12-module webinar-based group intervention focuses on suicide bereavement-related themes such as feelings of guilt, stigmatization, meaning reconstruction and the relationship to the deceased. Further, the webinar includes testimonial videos and psychoeducation. The suicide survivors are randomized to the intervention or the waiting list in a group-cluster randomized controlled trial. Primary outcomes are suicidality (Beck Scale for Suicide Ideation) and depression (Beck Depression Inventory-II) and secondary outcomes are symptoms of prolonged grief disorder (Inventory of Complicated Grief-German Version ), posttraumatic stress disorder ( Revised Impact of Event Scale ), stigmatization (Stigma of Suicide and Suicide Survivor ) and posttraumatic cognitions (Posttraumatic Cognitions Inventory).DiscussionPrevious studies of Internet-based interventions for the bereaved were based on writing interventions showing large treatment effects. Little is known about the use of webinars as group interventions. Advantages and challenges of this novel approach of psychological interventions will be discussed.Trial registrationGerman Clinical Trials Register, DRKS00014426.

The effectiveness of acceptance and commitment therapy on posttraumatic cognitions and psychological inflexibility among students with trauma exposure

Background: Posttraumatic stress disorder has a negative impact on the individual, family, and community due to disturbance in social functioning, increased stress, and life-threatening health status. Therefore, effective and useful therapeutic interventions in this area are very important. This study aimed at examining the effectiveness of acceptance and commitment therapy (ACT) on the posttraumatic cognitions of students with trauma exposure. Methods: In this quasi- experimental study, population included all students of Islamic Azad University in Roudehen, Tehran, Iran, during the academic year of 2018–2019. After administering trauma questionnaire, the second version of acceptance and action questionnaire (AAQ-II), and posttraumatic cognitions inventory (PTCI) to 500 people, 113 people who experienced trauma and had high scores in PTCI and low scores in AAQ-II were identified. Of whom 40 people were selected randomly. After the clinical interview, the subjects were randomly placed in the experimental group (who received ACT, n = 20) and placebo group (n = 20). Both groups were pre- and posttested using the PTCI and AAQ-II. Then, the obtained data were analyzed using covariance analysis. Results: The results showed that there was a significant difference in posttraumatic cognitions (negative cognitions about self, negative cognitions about the world, and self-blame) between the two groups. In addition, the results of posttest related to ACT had a significant impact on psychological inflexibility. In other words, ACT reduced posttraumatic cognitions and increased psychological flexibility of these students. Conclusion: The findings of the present study reveal that despite posttraumatic cognitions of students with trauma exposure, ACT increases value-based behaviors through increasing psychological flexibility and decreasing experiential avoidance.

Changes in Posttraumatic Cognitions Mediate the Effects of Trauma-Focused Therapy on Paranoia

Abstract Background Evidence suggests that in individuals with psychosis, paranoia is reduced after trauma-focused therapy (TFT) aimed at comorbid posttraumatic stress disorder (PTSD). Objective To identify mediators of the effect of TFT on paranoia. Method In a multicenter single-blind randomized controlled trial 155 outpatients in treatment for psychosis were allocated to 8 sessions Prolonged Exposure (PE; n = 53), 8 sessions Eye Movement Desensitization and Reprocessing (EMDR) therapy (n = 55), or a waiting-list condition (WL; n = 47) for treatment of comorbid PTSD. Measures were performed on (1) paranoia (GPTS); (2) DSM-IV-TR PTSD symptom clusters (CAPS-IV; ie, intrusions, avoidance, and hyperarousal); (3) negative posttraumatic cognitions (PTCI; ie, negative self posttraumatic cognitions, negative world posttraumatic cognitions and self-blame); (4) depression (BDI-II); and (5) cognitive biases (ie, jumping to conclusion, attention to threat, belief inflexibility, and external attribution), cognitive limitations (ie, social cognition problems and subjective cognitive problems), and safety behaviors (DACOBS). Outcome in terms of symptoms of paranoia (1) and potential mediators (2–5) were evaluated at posttreatment, controlling for baseline scores. Results The effects of TFT on paranoia were primarily mediated by negative self and negative world posttraumatic cognitions, representing almost 70% of the total indirect effect. Safety behaviors and social cognition problems were involved in the second step mediational pathway models. Conclusions Targeting the cognitive dimension of PTSD in TFT in psychosis could be an effective way to influence paranoia, whereas addressing safety behaviors and social cognition problems might enhance the impact of TFT on paranoia.

Delayed microglial depletion after spinal cord injury reduces chronic inflammation and neurodegeneration in the brain and improves neurological recovery in male mice.

Neuropsychological deficits, including impairments in learning and memory, occur after spinal cord injury (SCI). In experimental SCI models, we and others have reported that such changes reflect sustained microglia activation in the brain that is associated with progressive neurodegeneration. In the present study, we examined the effect of pharmacological depletion of microglia on posttraumatic cognition, depressive-like behavior, and brain pathology after SCI in mice.Methods: Young adult male C57BL/6 mice were subjected to moderate/severe thoracic spinal cord contusion. Microglial depletion was induced with the colony-stimulating factor 1 receptor (CSF1R) antagonist PLX5622 administered starting either 3 weeks before injury or one day post-injury and continuing through 6 weeks after SCI. Neuroinflammation in the injured spinal cord and brain was assessed using flow cytometry and NanoString technology. Neurological function was evaluated using a battery of neurobehavioral tests including motor function, cognition, and depression. Lesion volume and neuronal counts were quantified by unbiased stereology.Results: Flow cytometry analysis demonstrated that PLX5622 pre-treatment significantly reduced the number of microglia, as well as infiltrating monocytes and neutrophils, and decreased reactive oxygen species production in these cells from injured spinal cord at 2-days post-injury. Post-injury PLX5622 treatment reduced both CD45int microglia and CD45hi myeloid counts at 7-days. Following six weeks of PLX5622 treatment, there were substantial changes in the spinal cord and brain transcriptomes, including those involved in neuroinflammation. These alterations were associated with improved neuronal survival in the brain and neurological recovery.Conclusion: These findings indicate that pharmacological microglia-deletion reduces neuroinflammation in the injured spinal cord and brain, improving recovery of cognition, depressive-like behavior, and motor function.

Post-traumatic stress symptoms and cognition in children exposed to motor vehicle accident trauma

ABSTRACTResearch investigating the cognition of children exposed to non-familial trauma is scarce and the effects of post-traumatic stress symptoms in this population remain unclear. Thus, this research aimed to investigate the cognition of children exposed to motor vehicle accidents given the high incidence of this trauma globally. It was hypothesized that children with post-traumatic stress symptoms (PTSS; i.e., children with subthreshold or a full diagnosis of PTSD; n = 6) would perform significantly worse on cognitive measures compared to children exposed to trauma only (TO; i.e., children with very minimal or no PTSS; n = 10) and a healthy control group (n = 19). Analyses showed children with PTSS demonstrated significantly poorer perceptual reasoning F(2,32) = 7.21, p = .01, partial η2 = .31; verbal learning F(2,32) = 3.87, p = .05, partial η2 = .20; and delayed verbal memory F(2,32) = 4.40, p = .05, partial η2 = .22, compared to HCs. The magnitude of the differences between the groups was large. Differences in immediate verbal recall, executive functioning, and verbal intellectual abilities were moderate to large in magnitude, with the PTSS group performing worse than both groups, but these findings did not reach significance. Overall findings from this study provide further support for the notion that children exposed to non-familial trauma with significant PTSS display cognitive difficulties compared to healthy children.

Mechanisms of change in psychological interventions for posttraumatic stress symptoms: A systematic review with recommendations

Psychological interventions can alleviate posttraumatic stress symptoms (PTSS). However, further development of treatment approaches calls for understanding the mechanisms of change through which diverse interventions affect PTSS. We systematically searched the literature for controlled studies of mechanisms of change in psychological interventions for PTSS. We aimed to detect all empirically studied mechanisms and evaluate the level of evidence for their role in the alleviation of PTSS. We identified 34 studies, of which nine were among children. We found evidence for improvements in maladaptive posttraumatic cognitions as a general mechanism of change involved in diverse interventions, among both adults and children. We also found some preliminary evidence for increases in mindfulness as a mechanism of change in mindfulness- and spiritually-oriented interventions among adults. We found scant, mixed empirical evidence for other mechanisms of change. Notably, studies on changes in traumatic memories as a mechanism of change were lacking, despite clinical emphasis on their importance. A major limitation across reviewed studies was that most could not establish temporal order of changes in mechanisms and PTSS. Including thorough analyses of mechanisms of change beyond cognitions in all future trials and improving the reporting of findings would aid the development and implementation of even more effective interventions.

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.

Eye movement desensitization and reprocessing (EMDR)\xa0therapy for posttraumatic stress disorder in adults with serious mental illness within forensic and rehabilitation services: a study protocol for a randomized controlled trial

BackgroundEye movement desensitization and reprocessing (EMDR) is an evidenced-based treatment for posttraumatic stress disorder (PTSD). Forensic mental health services provide assessment and treatment of people with mental illness and a history of criminal offending, or those who are at risk of offending. Forensic mental health services include high, medium, and low-security inpatient settings as well as prison in-reach and community outpatient services. There is a high prevalence of PTSD in forensic settings and posttraumatic experiences can arise in people who violently offend in the context of serious mental illness (SMI). Successful treatment of PTSD may reduce the risk of relapse and improve clinical outcomes for this population. This study aims to assess the efficacy, risk of harm, and acceptability of EMDR within forensic and rehabilitation mental health services, as compared to treatment as usual (routine care).MethodsThis is a single-blind, randomized controlled trial comparing EMDR therapy to the waiting list (routine care). Adult forensic mental health service users (n = 46) with SMI and meeting the criteria for PTSD will be included in the study. Participants will be randomized after baseline assessment to either treatment as usual plus waiting list for EMDR or to treatment as usual plus EMDR. The EMDR condition comprises nine sessions, around 60 min in length delivered weekly, the first of which is a case conceptualization session. The primary outcomes are clinician and participant-rated symptoms of PTSD, and adverse events. Secondary outcomes include psychotic symptoms, social functioning, level of disability, self-esteem, depressive symptoms, post-trauma cognitions, and broad domains of complex posttraumatic difficulties. A trained assessor blinded to the treatment condition will assess outcomes at baseline, 10 weeks, and 6 months. Additionally, grounded theory qualitative methods will be used to explore participant experience of EMDR for a subset of participants.DiscussionThis study will contribute to the currently limited evidence base for EMDR for PTSD in forensic settings. It is the first randomized clinical trial to assess the efficacy, risk of harm, and acceptability of EMDR for PTSD in people with SMI in either forensic, mental health inpatient, or custodial settings.Trial registrationAustralia and New Zealand Clinical Trials Network, ACTRN12618000683235.

Dysfunctional posttraumatic cognitions, posttraumatic stress and depression in children and adolescents exposed to trauma: a network analysis.

The latest version of the International Classification of Diseases (ICD-11) proposes a posttraumatic stress disorder (PTSD) diagnosis reduced to its core symptoms within the symptom clusters re-experiencing, avoidance and hyperarousal. Since children and adolescents often show a variety of internalizing and externalizing symptoms in the aftermath of traumatic events, the question arises whether such a conceptualization of the PTSD diagnosis is supported in children and adolescents. Furthermore, although dysfunctional posttraumatic cognitions (PTCs) appear to play an important role in the development and persistence of PTSD in children and adolescents, their function within diagnostic frameworks requires clarification. We compiled a large international data set of 2,313 children and adolescents aged 6 to 18years exposed to trauma and calculated a network model including dysfunctional PTCs, PTSD core symptoms and depression symptoms. Central items and relations between constructs were investigated. The PTSD re-experiencing symptoms strong or overwhelming emotions and strong physical sensations and the depression symptom difficulty concentrating emerged as most central. Items from the same construct were more strongly connected with each other than with items from the other constructs. Dysfunctional PTCs were not more strongly connected to core PTSD symptoms than to depression symptoms. Our findings provide support that a PTSD diagnosis reduced to its core symptoms could help to disentangle PTSD, depression and dysfunctional PTCs. Using longitudinal data and complementing between-subject with within-subject analyses might provide further insight into the relationship between dysfunctional PTCs, PTSD and depression.

Posttraumatic cognitions, childhood sexual abuse characteristics, and posttraumatic stress disorder in men who have sex with men

BackgroundHigh rates of experience of childhood sexual abuse (CSA) among in men who have sex with men (MSM) place this population at increased risk for posttraumatic stress disorder (PTSD). ObjectiveThis study explores how specific characteristics of CSA relate to posttraumatic cognitions (PTCs) and explores the role that specific PTCs play in the relationship between CSA and PTSD in MSM. MethodsTwo-hundred and ninety MSM completed a CSA interview, the Davidson Trauma Scale, and the Posttraumatic Cognitions Inventory. ResultsControlling for sociodemographic factors, CSA involving physical injury and CSA with intense fear were associated with higher levels of PTCs about the self and world, but not with self-blame. We did not find significant associations for CSA involving a family member, CSA with penetration, or duration or frequency of CSA with any subscale on the PTCI. Experiencing CSA for the first time during adolescence was associated with higher self-blame. Analyses revealed that physical injury and intense fear each had indirect effects on PTSD symptoms through negative cognitions about the self and world. First CSA episode during adolescence had an indirect effect on PTSD symptoms through self-blame. CSAs accounted for 16.7% and PTCs accounted for 31.7% of the variance in PTSD, underlining the importance of PTCs. ConclusionsAssessing for physical injury, intense fear, and age at first CSA are particularly relevant to PTCs and of critical importance to advancing assessment and treatment strategies for PTSD in MSM.

Dissociative subtype of posttraumatic stress disorder in women in partial and residential levels of psychiatric care

ABSTRACT The dissociative subtype of posttraumatic stress disorder (PTSD) is estimated to characterize about 12-30% of those with PTSD. Some research links this subtype with increased severity of PTSD symptoms compared to samples with “classic” PTSD. However, prevalence and severity rates reported in the literature have varied. One possible explanation for these discrepancies could be related to where the populations were sampled. Therefore, we investigated whether these differences are still observed when holding level of care constant. We collected data from 104 women at a partial and residential psychiatric hospital program focused on trauma-related disorders. Participants completed self-report questionnaires assessing trauma exposure, symptoms and provisional diagnosis of PTSD, trauma-related thoughts and beliefs, and feelings of shame. All participants reported a history of childhood and/or adulthood trauma exposure. Eighty-eight (85%) met criteria for PTSD, and of those, seventy-three (83%) met criteria for the dissociative subtype as assessed by the Dissociative Subtype of PTSD Scale. A series of independent t-tests revealed no significant differences between the “classic” and dissociative PTSD groups with respect to lifetime or childhood trauma exposure, posttraumatic cognitions, shame, or overall PTSD severity. Our results suggest that samples with classic PTSD and the dissociative subtype may not differ in some types of symptom severity when holding level of care constant. Importantly, however, we found at partial/residential level of care the majority of patients with PTSD were dissociative. Given the elevated prevalence rate in this sample, these findings support the need to assess dissociative symptoms, particularly in more acute psychiatric settings.

Parental dysfunctional posttraumatic cognitions in trauma-focused cognitive behavioral therapy for children and adolescents.

Trauma-therapy in children and adolescents often involves the inclusion of their parents. A multi-informant approach was used to investigate whether trauma-focused cognitive-behavioral therapy (TF-CBT) changes dysfunctional posttraumatic cognitions (PTCs) in participating parents. This, in turn, may mediate their child's posttraumatic stress symptoms (PTSS) posttreatment. Children and adolescents (6-17 years old) were assigned to either a TF-CBT (n = 57) or a waitlist (n = 56) condition, within a multisite randomized controlled trial conducted in Germany. They were assessed using the Clinician Administered PTSD Scale for Children and Adolescents, version for DSM-IV and they completed the University of California at Los Angeles Post-Traumatic Stress Disorder Reaction Index for Children and Adolescents (UCLA). Their parents completed the UCLA, caregiver report, and the Posttraumatic Cognitions Inventory to rate their dysfunctional PTCs related to their child's trauma. The mediation hypothesis was tested using a multiple mediation model. The change in parental PTCs was stronger in the TF-CBT condition (b = 13.19, 95% confidence interval [CI] [2.89, 23.49]). It mediated the relationship between the group (TF-CBT vs. waitlist) and the caregiver report on the child's PTSS (b = -.08, 95% CI [-.15, -.01]), but not the child's PTSS, assessed using the interview (b = .01, 95% CI [-.14, .17]) and the self-report questionnaire (b = .01, 95% CI [-.08, .10]), posttreatment. TF-CBT helped participating parents to challenge their dysfunctional PTCs related to their child's trauma. The change in parental PTCs only mediated their perception of their child's PTSS but not their child's self-perception or the clinical evaluation of their child's PTSS.

Gendered racial microaggressions predict posttraumatic stress disorder symptoms and cognitions among Black women living with HIV.

Gendered racial microaggression (GRM) experienced by Black women living with HIV (BWLWH) is a potentially important variable for posttraumatic stress disorder (PTSD) symptomatology in this population. GRM refers to everyday insults experienced by Black women on the basis of being both Black and female (e.g., comments about Black women's hair and body). We investigated the associations between GRM, race- and HIV-related discrimination, and trauma symptoms among BWLWH and explored whether gendered racial microaggressions contributed uniquely to trauma symptoms above the contribution of race- and HIV-related discrimination. One-hundred BWLWH in the U.S. completed baseline measures on GRM (frequency and appraisal), racial discrimination, HIV-related discrimination, PTSD symptoms, and posttraumatic cognitions. Hierarchical multiple linear regressions controlling for age, education, and income indicated that higher GRM and HIV-related discrimination predicted higher total PTSD symptoms, and higher GRM and racial discrimination predicted higher posttraumatic cognitions. Hierarchical multiple linear regressions with all predictors entered together revealed that only GRM contributed uniquely to both total PTSD symptoms and total posttraumatic cognitions. Analyses between GRM subscales and subscales of PTSD symptoms and posttraumatic cognitions indicated that GRM about beauty/sexual objectification and the strong Black women stereotype contributed uniquely and in interesting ways to PTSD symptoms and posttraumatic cognitions. Our findings highlight the importance of addressing intersectional adversities such as GRM for BWLWH, as well as recognizing the role that GRM may play in mental health symptoms for Black women. Future research and intervention efforts aimed at improving the well-being of BWLWH should address GRM. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Effects of processing positive memories on posttrauma mental health: A preliminary study in a non-clinical student sample

Background and objectivesAlthough trauma research and therapy primarily focus on traumatic memories, recent evidence indicates positive memory processes play a role in the etiology/maintenance of posttraumatic stress disorder (PTSD) symptom severity. We examined the effects of a novel positive memory processing technique on PTSD symptom severity, depression symptom severity, affect, posttrauma cognitions, and self-esteem. MethodsSixty-five trauma-exposed participants were randomly assigned to one of three conditions (narrating/processing vs. writing/processing two specific positive memories, or a time-matched control) and completed self-report measures pre- and post-task (T0). About one week later, participants repeated their assigned task condition and completed self-report measures pre- and post-task (T1). We conducted mixed ANOVAs to examine the impact of the technique on study variables over time. ResultsThe narrating condition had significant decreases in PTSD symptom severity, posttrauma cognitions, and negative affect from T0 pre-task to T1 post-task; and significant increases in positive affect from T0 pre-to-post-task and from T1 pre-to-post-task. The writing condition had significant increases in positive affect from T0 pre-to-post-task, but a significant decrease from T0 post-task to T1 post-task; and significant decreases in negative affect from T0 pre-to-post-task with an increase from T0 post-task to T1 post-task. LimitationsUse of self-report measures, non-clinical convenience sample with less gender/ethnic/racial diversity, small sample size, methodological differences in time frames for measures, and no examination of follow-up effects. ConclusionsNarrating and processing specific positive memories had a beneficial impact on PTSD symptom severity, posttrauma maladaptive cognitions, and affect; such results provide an impetus to examine positive memory interventions in trauma clinical work.

PTSD severity among emergency personnel: An investigation based on the Ehlers and Clark cognitive model.

The relevance of both cognitive and interpersonal processes in predicting adjustment to potentially traumatic events has been highlighted in the literature. The aim of the present study was to investigate whether dysfunctional disclosure mediates the relationship between excessive negative appraisals and posttraumatic stress disorder (PTSD) symptomatology that is proposed in the cognitive PTSD model of Ehlers and Clark (2000). A sample of 134 emergency service workers was interviewed to gain in-depth information regarding their experience of potentially traumatic events, and the following social interactions. Additionally, participants responded to the Disclosure of Trauma Questionnaire, the Posttraumatic Cognitions Inventory, and the Impact of Event Scale-Revised. Bootstrap mediation analyses revealed that the effect of negative trauma related appraisals on PTSD symptoms is partly mediated by dysfunctional disclosure. In particular, the two aspects of dysfunctional disclosure "reluctance to talk" and "excessive emotional reactions during disclosure" were of relevance in this model. The results remained stable even when controlling for potentially relevant sociodemographic and situational characteristics. Our results stress the importance of not only cognitive factors, but also interpersonal behavior in the development and maintenance of PTSD symptoms because we identified interpersonal risk factors (i.e., dysfunctional communicative strategies) to be relevant for PTSD elevation.

Pain in the Acute Aftermath of Stalking: Associations With Posttraumatic Stress Symptoms, Depressive Symptoms, and Posttraumatic Cognitions.

This longitudinal study examined whether posttraumatic stress and depressive symptoms, posttraumatic cognitions, and ongoing cyberstalking exposures were independently associated with changes in pain outcomes among 82 young adult women with recent exposure to stalking. Multilevel models indicated that higher sensory pain intensity and pain-related interference were associated with more negative cognitions about the self. Higher affective pain intensity was associated with higher posttraumatic stress and depressive symptoms. Cyberstalking exposures were not associated with pain intensity or pain-related interference. Results reveal persistent pain complaints in recent stalking victims and highlight distinct psychological risk factors for pain intensity and pain-related interference.

Post-traumatic stress and psychological health following infidelity in unmarried young adults.

Infidelity is often conceptualized as a traumatic event; however, little research has explored this topic empirically, particularly in unmarried adults. We determined the prevalence of infidelity-related post-traumatic stress disorder (PTSD) symptoms among unmarried adults who experienced a partner's infidelity and whether probable infidelity-related PTSD was associated with additional psychological health outcomes (i.e., depressive symptoms, perceived stress, and anxiety symptoms). We also investigated whether negative post-traumatic cognitions mediated the associations between infidelity-related PTSD symptoms and psychological health. This study included 73 adults (M age = 19.42, SE = 0.19 years) who experienced infidelity within a committed nonmarital relationship within the last 5 years. Controlling for gender, race, and exposure to Diagnostic and Statistical Manual of Psychiatric Disorders Criterion A traumas, 45.2% of our sample reported symptoms suggesting probable infidelity-related PTSD. Whether used as continuous or categorical predictor, infidelity-related PTSD symptoms were significantly associated with depressive symptoms, although results for perceived stress and anxiety symptoms were mixed. Post-traumatic cognitions acted as a partial mediator for depressive symptoms and full mediator for perceived stress and anxiety symptoms. This empirical evidence suggests that infidelity may produce PTSD symptoms at a relatively high rate, even in unmarried young adults, and may put individuals at risk for poorer psychological health, partially through post-traumatic cognitions.

Longitudinal Associations Between Dysfunctional Maltreatment-Related Cognitions and Psychopathology in Children and Adolescents.

Dysfunctional posttraumatic cognitions seem to play an important role in adjustment after traumatic experiences. However, little research has been done on maltreated children and adolescents. Furthermore, possible causal associations between cognitions, posttraumatic stress symptoms, and internalizing and externalizing problems have rarely been investigated. In the current study, 263 maltreated children and adolescents (8-17 years of age) were assessed at baseline and again at time points 6 and either 12 or 18 months later. Cross-lagged panel analyses were used to gain a better understanding of the course of and associations among dysfunctional maltreatment-related cognitions, posttraumatic stress symptoms, and internalizing and externalizing problems. Ratings of all variables significantly decreased over time. Moderate to strong autoregressive paths emerged for all variables, denoting stability. Furthermore, the variables showed moderate to high correlations at every assessment. Posttraumatic stress symptoms moderately predicted dysfunctional maltreatment-related cognitions as well as internalizing and externalizing problems 6 months after baseline. Cross-lagged paths from the cognitions as well as from internalizing and externalizing problems to all other variables were not significant. Age, gender, and maltreatment characteristics did not play a relevant role in these cross-lagged associations when they were included as covariates. Our results underline the cognitive scar model, in which preceding posttraumatic stress symptoms adversely impact cognitions. Posttraumatic stress symptoms appear to be an important target for treatment as their reduction may help decrease internalizing and externalizing problems as well.

Appraisal-based cognitive bias modification in patients with posttraumatic stress disorder: a randomised clinical trial

ABSTRACT Background: Negative appraisals of the trauma and its sequelae play a crucial role in the development and maintenance of Posttraumatic Stress Disorder (PTSD). Experimental studies have shown promise in reducing negative appraisal through Cognitive Bias Modification (CBM) training. Objective: To determine whether an online CBM training designed to modify dysfunctional appraisals is successful in reducing appraisal bias in PTSD patients. Method: In this double-blinded 2-arm randomised clinical trial, 107 patients with PTSD were randomly allocated to active (n = 49) or control online CBM training (n = 57). Training comprised the completion of four sessions of online CBM training within one week. Change in bias, as measured by a scenario task and questionnaire (i.e. PostTraumatic Cognition Inventory), was the primary outcome. Secondary outcome included change in PTSD symptoms. Assessments took place prior to training, during training sessions, post-training and at 1- and 6-month follow-up. Results: Intent-to-treat analysis indicated that there was no interaction effect of condition by time. Regardless of training condition, participants showed a small to moderate decline in appraisal bias and PTSD symptoms from pre- to post-training. In both conditions, bias change during training sessions was related to decline in PTSD symptomatology following training. No moderators of outcome were found. Conclusions: There was no evidence that active training was more effective than control training in reducing dysfunctional appraisals. In both conditions, participants showed a decline in dysfunctional appraisals and PTSD symptoms following training. Importantly, bias reduction during training was related to PTSD symptom decline following training. Explanations and future research directions are discussed.
