Objective: To investigate the extent to which negative posttraumatic cognitions predict, and so can be best located within, the DSM-5 (APA, 2013) individual symptom clusters of posttraumatic stress disorder (PTSD). Method: An online survey of traumatic experiences, featuring 528 adults. Results: Negative posttraumatic cognitions seem best placed within the Numbing/Detachment symptom cluster. Negative posttraumatic cognitions relating to the self predict higher levels of symptoms across the clusters. While negative cognitions relating to the world contributed to most symptom groups, self-blame cognitions did not. Conclusions: Our findings support the placement of posttraumatic cognitions as part of the Numbing/Detachment symptom cluster within the DSM-5 rather than the Intrusion, Avoidance and Hyperarousal clusters.
Behavioral Self-Blame in PTSD—Etiology, Risk Factors, and Proposed Interventions
International Journal of Environmental Research and Public Health
Background: Feeling out of control during a traumatic event may evoke behavioral self-blame (BSB) to avoid feeling helpless following trauma by restoring one’s sense of control. BSB is a common, persistent, and treatment-resistant post-traumatic stress symptom. The present study investigates the etiology and risk factors of BSB following a traumatic event and the reasons for its persistence over time. Method: Subjects were a group of 546 Israeli ex-combat soldiers (M age = 24.93 ± 5.657) registered in an Israel Defense Forces (IDF) combat reaction clinic. All completed the Peritraumatic Dissociative Experiences Questionnaire (PDEQ), the Brief Symptom Inventory (BSI), and the PTSD Checklist for the DSM-5 (PCL-5). Item 10 of the PCL-5 served to measure BSB. The PDEQ and BSI measured distress and feeling out of control during the event. We used descriptive analyses of the data, t-test, and linear regression analysis to reveal the relationship between the research variables. Results: Fe...

The current report used confirmatory factor analysis to examine the latent structures of both key features and associated symptoms of three disorders that commonly develop following a traumatic event: posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and generalized anxiety disorder (GAD). Participants were 228 motor-vehicle accident survivors who sought treatment for emotional difficulties. PTSD, MDD, and GAD were assessed with a combination of self-report and interview-based measures. The results of construct level analyses suggested that PTSD, MDD, and GAD are distinguishable but highly correlated disorders following a traumatic event. Symptom level analyses supported a model where the Reexperiencing, Avoidance, and Hypervigilance factors were subsumed under the PTSD construct. However, in this model the Dysphoria factor was a higher order construct correlated with the PTSD, MDD, and GAD factors, suggesting that the Dysphoria cluster may not be unique to PTSD. Diagnostic and theoretical implications of these results are discussed.
In order to broaden theoretical models of adaptation following trauma and inform current diagnostic practices, the goal of the current study was to examine associations between negative emotions and dysfunctional trauma-related cognitions. In a sample of 109 women who were seeking mental health assistance after intimate partner violence (IPV), anxiety, depression, shame, and guilt were explored in association with negative thoughts about the self, negative thoughts about the world, and self-blame. Higher levels of shame and depression were significantly associated with higher levels of negative thoughts about the self. An increased level of guilt was the only significant finding in the analysis involving negative thoughts about the world. Lower levels of depression and higher levels of shame and guilt were significantly associated with increased levels of self-blame. Anxiety did not emerge as a significant predictor in any of these analyses. Implications for current models of posttraumatic stress disorder (PTSD), revisions to diagnostic practices, and treatment of individuals who have experienced interpersonal trauma are discussed.
The Posttraumatic Cognitions Inventory (PTCI): Development and validation
Psychological Assessment, 1999
This article describes the development and validation of a new measure of trauma-related thoughts and beliefs, the Posttraumatic Cognitions Inventory (PTCI), whose items were derived from clinical observations and current theories of post-trauma psychopathology. The PTCI was administered to 601 volunteers, 392 of whom had experienced a traumatic event and 170 of whom had moderate to severe posttraumatic stress disorder (PTSD). Principal-components analysis yielded 3 factors: Negative Cognitions About Self, Negative Cognitions About the World, and Self-Blame. The 3 factors showed excellent internal consistency and good test-retest reliability; correlated moderately to strongly with measures of PTSD severity, depression, and general anxiety; and discriminated well between traumatized individuals with and without PTSD. The PTCI compared favorably with other measures of trauma-related cognitions, especially in its superior ability to discriminate between traumatized individuals with and without PTSD.

Cognitive models of post-traumatic stress disorder (PTSD) posit that negative cognitions regarding the self and the world underlie the disorder. In contrast, scarring modelswhich postulate that distress brings about an elevation in vulnerabilitypredict the inverse relationship. Both models were tested amongst 156 Israeli trauma victims. Participants were assessed for PTSD symptoms and trauma-related cognitions (negative thoughts regarding self and world) over 2 weeks (T1), 4 weeks (T2), and 12 weeks (T3) following the traumatic event. A cross-lagged structural equation modeling analysis yielded evidence for both cognitive vulnerability and scarring. Baseline PTSD was prospectively associated with an increase in negative cognitions regarding both the self and the world during the T1-T2 period. Negative cognitions regarding the self were prospectively associated with an increase in PTSD symptoms during both T1-T2 and T2-T3 periods. PTSD symptoms and negative cognitions regarding the self thus appear to form a vicious cognitive-symptomatic cycle which might impede recovery.
The Relationship of PTSD to Negative Cognitions: A 17-Year Longitudinal Study
With the growing interest in the role of cognitions in PTSD, this prospective study examined the course and bi-directional relationship between post-trauma cognitions and symptoms of PTSD. A sample of Israeli combat veterans, including former prisoners of war, was assessed in 1991, and later followed up in 2003 and 2008. PTSD symptoms were measured at three time points. Cognitions concerning the self and the world were measured twice. Applying Autoregressive Cross-Lagged (ARCL) modeling strategy, initial PTSD symptoms predicted subsequent negative cognitions but not vice versa. In addition, repeated measures design revealed that individuals with chronic PTSD symptoms had relatively negative cognitions that further amplified with time. More specifically, increasingly negative cognitions were documented among ex-prisoners of war. The main findings suggest that negative cognitions are fueled by PTSD and that in chronic PTSD there is an amplification of pathogenic outcomes over time. Discussion of the findings is in the context of current cognitive models of PTSD.

The International Classification of Diseases, 11th version (ICD-11), proposes two related stress and trauma-related disorders, posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD). A diagnosis of CPTSD requires that in addition to the PTSD symptoms, an individual must also endorse symptoms in three major domains: (1) affective dysregulation, (2) negative self-concepts, and (3) interpersonal problems. This study aimed to determine if the naturally occurring distribution of symptoms in three groups of traumatised individuals (bereavement, sexual victimisation, and physical assault) were consistent with the ICD-11, PTSD, and CPTSD specification. The study also investigated whether these groups differed on a range of other psychological problems. Participants completed self-report measures of each symptom group and latent class analyses consistently found that a three class solution was best. The classes were "PTSD only," "CPTSD," and "low PTSD/CPTSD.&q...
