Isobel S. Trauma and the perinatal period: A review of the theory and practice of trauma-sensitive interactions for nurses and midwives. Nurs Open 2023; 10:7585-7595. [PMID: 37775971 PMCID: PMC10643851 DOI: 10.1002/nop2.2017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 08/30/2023] [Accepted: 09/17/2023] [Indexed: 10/01/2023] Open
Abstract
AIM With high rates of trauma in the population, known links between trauma and perinatal distress, and the intimate and close nature of the nursing and midwifery roles, ensuring awareness and understandings of trauma is crucial for guiding practice. This paper aims to explore the relationship of trauma to the perinatal period, based on theory and practice, to consider on how nurses and midwives can deliver trauma-sensitive interactions. DESIGN AND METHODS This discursive discussion draws on relevant research from the fields of trauma therapy, attachment theory and nursing and midwifery practice to consider elements of trauma-sensitive practice in the perinatal period. RESULTS Nurses and midwives can foster safety for people who have experienced trauma through noticing and responding to triggers, supporting awareness of attachment and its relationships to trauma, undertaking psychosocial screening with care, supporting linearity and cohesion in narratives and developing collaborative care plans that maximise safety and agency. For nurses and midwives, understandings of the relationship between trauma, pregnancy, birth, early parenting and distress is crucial for effective care delivery. Delivering perinatal nursing or midwifery care of any kind, without universal trauma precautions risks reinforcing, misinterpreting or re-enacting dynamics of trauma. To be trauma-sensitive in this period requires nurses and midwives to have awareness of the dynamics of trauma in relation to pregnancy, birth and attachment. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE This paper fills a gap in the translation of theory to practice for trauma-sensitive care in the perinatal period, with a focus on the therapeutic relationship formed by nurses and midwives. The findings highlight that nurses and midwives can foster safety for people who have experienced trauma within their practice, when they hold a robust understanding of the relationship between trauma, pregnancy, birth, early parenting and distress.

Miragoli S, Camisasca E. An Examination of the Synergy of Age and PTSD on Narrative Coherence in Child Sexual Abuse Testimony. JOURNAL OF CHILD SEXUAL ABUSE 2022; 31:743-757. [PMID: 36197834 DOI: 10.1080/10538712.2022.2131669] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 06/30/2022] [Accepted: 07/27/2022] [Indexed: 06/16/2023]
Abstract
In a criminal proceeding, a witness is considered as reliable if he/she can recall in narrative form the events, chronologically ordered, with salient contextual (place and time) details, and essential evaluations for the definition of meanings. This study aimed to confirm the effects of age and PTSD on narrative coherence and to investigate the moderating role of age on the association between PTSD and narrative coherence. Narrative coherence was analyzed in 92 allegations of children (M = 10.3; range: 4-17), who were victims of sexual abuse. Thirty-five children presented the symptoms for a diagnosis of PTSD. Each deposition has been codified through the Narrative Coherence Coding Scheme, a coding scheme based on the three independent dimensions (context, chronology, and theme). Correlation analysis indicated the positive associations between age and context, chronology, and theme; and the negative associations between PTSD symptoms and context, chronology, and theme. Predictive effect of PTSD became less and less significant with increasing age. This study could underline the importance of age and PTSD (and their synergy) in legal testimony of children who have been sexually abused.

Abstract
Post-traumatic stress disorder (PTSD) is a debilitating mental illness composed of a heterogeneous collection of symptom clusters. The unique nature of PTSD as arising from a precipitating traumatic event helps simplify cross-species translational research modeling the neurobehavioral effects of stress and fear. However, the neurobiological progress on these complex neural circuits informed by animal models has yet to produce novel, evidence-based clinical treatment for PTSD. Here, we provide a comprehensive overview of popular laboratory models of PTSD and provide concrete ideas for improving the validity and clinical translational value of basic research efforts in humans. We detail modifications to simplified animal paradigms to account for myriad cognitive factors affected in PTSD, which may contribute to abnormalities in regulating fear. We further describe new avenues for integrating different areas of psychological research underserved by animal models of PTSD. This includes incorporating emerging trends in the cognitive neuroscience of episodic memory, emotion regulation, social-emotional processes, and PTSD subtyping to provide a more comprehensive recapitulation of the human experience to trauma in laboratory research.

Abstract
OBJECTIVE Identify issues that are important to severe trauma survivors up to 3 years after the trauma. BACKGROUND Severe trauma is the first cause of disability-adjusted life years worldwide, yet most attention has focused on acute care and the impact on long-term health is poorly evaluated. METHOD We conducted a large-scale qualitative study based on semi-structured phone interviews. Qualitative research methods involve the systematic collection, organization, and interpretation of conversations or textual data with patients to explore the meaning of a phenomenon experienced by individuals themselves. We randomly selected severe trauma survivors (abbreviated injury score ≥3 in at least 1 body region) who were receiving care in 6 urban academic level-I trauma centers in France between March 2015 and March 2018. We conducted double independent thematic analysis. Issues reported by patients were grouped into overarching domains by a panel of 5 experts in trauma care. Point of data saturation was estimated with a mathematical model. RESULTS We included 340 participants from 3 months to 3 years after the trauma [median age: 41 years (Q1-Q3 24-54), median injury severity score: 17 (Q1-Q3 11-22)]. We identified 97 common issues that we grouped into 5 overarching domains: body and neurological issues (29 issues elicited by 277 participants), biographical disruption (23 issues, 210 participants), psychological and personality issues (21 issues, 147 participants), burden of treatment (14 issues, 145 participants), and altered relationships (10 issues, 87 participants). Time elapsed because the trauma, injury location, or in-hospital trauma severity did not affect the distribution of these domains across participants' answers. CONCLUSIONS This qualitative study explored trauma survivors' experiences of the long-term effect of their injury and allowed for identifying a set of issues that they consider important, including dimensions that seem overlooked in trauma research. Our findings confirm that trauma is a chronic medical condition that demands new approaches to post-discharge and long-term care.

Abstract
While trauma memory characteristics are considered a core predictor of adult PTSD, the literature on child PTSD is limited and inconsistent. We investigated whether children's trauma memory characteristics predict their posttraumatic stress symptoms (PTSS) at 1 month and 6 months post-trauma. We recruited 126 6-13 year olds who experienced a single-incident trauma that led to attendance at an emergency department. We assessed trauma memory disorganisation and sensory-emotional qualities through both narrative recall and self-report questionnaire, and PTSS at 1-month post-trauma and at 6-month follow-up. We found that, after controlling for age, children's self-reported trauma memory characteristics were positively associated with their concurrent PTSS, and longitudinally predicted symptoms 6-months later. However, observable trauma memory characteristics coded from children's narratives were not related to PTSS at any time. This suggests that children's perceptions of their trauma memories are a more reliable predictor of the development and maintenance of PTSS than the nature of their trauma narrative, which has important implications for clinical practice.

Abstract
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.

Abstract
Theoretical models of posttraumatic stress disorder (PTSD) as well as exposure therapy (EXP) methodology suggest that trauma recall is crucial to altering the conditioned fear response associated with PTSD. However, it is unclear whether limited recall of the trauma event attenuates treatment outcomes. This study examined whether the extent of difficulty recalling aspects of a traumatic event affected fear activation, habituation, number of sessions, session length, and diagnostic outcomes in 166 Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn veterans. Extent of trauma recall difficulty neither attenuated veterans' ability to achieve fear activation and habituation nor affected treatment outcomes. Findings suggest that even veterans who reported greater difficulty recalling their trauma event can engage successfully and benefit from EXP. This research is the first to examine trauma event recall in the context of the EXP process and contributes to the current body of literature that aims to address the question: "For whom do treatments work?"

Abstract
Smaller hippocampal volume is associated with increased risk for PTSD following trauma, but the hippocampal functions involved remain unknown. We propose a conceptual model that identifies broad impairment in hippocampus-dependent associative learning as a vulnerability factor for PTSD. Associative learning of foreground cues and background context is required to form an integrated representation of an event. People with poor associative learning may have difficulty remembering who or what was present during a trauma, where the trauma occurred, or the sequence of events, which may contribute to PTSD symptoms. We argue that associative learning difficulties in PTSD exist for cues and context, regardless of the emotional nature of the information. This contrasts with PTSD models that focus exclusively on threat-processing or contextual-processing. In a meta-analysis, people with PTSD exhibited poor associative learning of multiple information types compared to those without PTSD. Differences were of medium effect size and similar magnitude for neutral and negative/trauma-related stimuli. We provide evidence for associative learning difficulties as a neurocognitive pathway that may contribute to PTSD.

Abstract
Clinical theories of posttraumatic stress disorder (PTSD) suggest that trauma
memories are disorganized. In the present study, we examined how trauma-film
exposure affects two aspects of memory disorganization, poor memory recall and
memory disjointedness, and their relationship to PTSD-like symptoms. In Session
1, 90 healthy participants were exposed to a trauma (n = 60) or
a neutral film (n = 30). Cognitive processing styles, memory
characteristics, and intrusive memories of the film were assessed. The
trauma-film group reported greater memory disjointedness of the worst moments of
the film but better memory recall of the film than the neutral-film group. In
the trauma-film group, cognitive processing and memory disjointedness were
related to intrusive memories and PTSD-like symptoms in the week after film
exposure. Memory disjointedness but not poor memory recall mediated the
relationship between cognitive processing and intrusions. The findings suggest
that different aspects of memory disorganization need to be distinguished to
explain PTSD symptoms.

Abstract
Background Language is the most common way to communicate internal states and emotions into a narrative form. Studies on the use of language provide a useful understanding of how people process an event and interpret it. Objective The aim of this study was to investigate the effects of PTSD on the narrative coherence of children's reports of sexual abuse. Participants and setting Narrative coherence was analyzed within a group of 89 allegations of children (M = 10; range: 4–16), who were victims of sexual abuse. Thirty-seven children presented the symptoms for a diagnosis of PTSD. Method Linguistic Inquiry Word Count (LIWC) was employed and narrative coherence was analyzed through some linguistic markers (first-person singular pronouns, conjunctions, and cognitive words). Results Results illustrated the effects of PTSD on the narrative coherence, in terms of first-person singular pronouns, conjunctions, and cognitive processes. Indeed, compared with traumatic narratives of children without PTSD, traumatic narratives of children with PTSD contained a greater number of first-person singular pronouns (MPTSD = 1.45 versus Mno-PTSD = 1.12) and a smaller number of conjunctions (MPTSD = .37 versus Mnon-PTSD = .67), cognitive (MPTSD = 2.93 versus Mnon-PTSD = 3.76) and insight words (MPTSD = 2.29 versus Mnon-PTSD = 3.09). Regression analyses were used to examine if age and PTSD were predictors of the narrative coherence, suggesting the effects of PTSD in predicting the use of the first-person singular pronouns and the conjunctions. Conclusion This study could underline the importance of considering the PTSD in legal testimony of children who have been sexually abused.

Abstract
Research suggests important associations between emotion regulation difficulties and posttraumatic stress disorder (PTSD) symptomology, with prospective studies indicating that emotion regulation difficulties may lead to increased PTSD symptoms. Peritraumatic dissociation is considered an important and consistent predictor of PTSD symptoms. The present study examines whether peritraumatic dissociation accounts for associations between facets of emotion regulation difficulties and PTSD symptoms. Adult women with a history of sexual victimization participated in an interview to assess past-month PTSD symptoms and self-report questionnaires to assess peritraumatic dissociation and emotion regulation difficulties. Results showed a partial indirect effect of three facets of emotion regulation difficulties (i.e., nonacceptance of negative emotional responses, limited access to emotion regulation strategies perceived as effective in the context of distress, and impulse control difficulties when experiencing negative emotions) on PTSD symptoms through peritraumatic dissociation. Reverse indirect effects models were also explored. The present study offers preliminary evidence that peritraumatic dissociation by traumatized individuals may signal the presence of specific emotion regulation deficits, which may indicate increased risk of heightened PTSD severity.

Abstract
Autobiographical memory forms a network of memories about personal experiences that defines and supports well-being and effective functioning of the self in various ways. During the last three decades, there have been two characteristics of autobiographical memory that have received special interest regarding their role in psychological well-being and psychopathology, namely memory specificity and memory coherence. Memory specificity refers to the extent to which retrieved autobiographical memories are specific (i.e., memories about a particular experience that happened on a particular day). Difficulty retrieving specific memories interferes with effective functioning of the self and is related to depression and post-traumatic stress disorder. Memory coherence refers to the narrative expression of the overall structure of autobiographical memories. It has likewise been related to psychological well-being and the occurrence of psychopathology. Research on memory specificity and memory coherence has developed as two largely independent research domains, even though they show much overlap. This raises some important theoretical questions. How do these two characteristics of autobiographical memory relate to each other, both theoretically and empirically? Additionally, how can the integration of these two facilitate our understanding of the importance of autobiographical memory for the self? In this article, we give a critical overview of memory specificity and memory coherence and their relation to the self. We link both features of autobiographical memory by describing some important similarities and by formulating hypotheses about how they might relate to each other. By situating both memory specificity and memory coherence within Conway and Pleydell-Pearce’s Self-Memory System, we make a first attempt at a theoretical integration. Finally, we suggest some new and exciting research possibilities and explain how both research fields could benefit from integration in future research.

Abstract
The present study aimed to assess the effects of age and PTSD on the narrative fragmentation in memories for child sexual abuse. Lexical complexity, cohesion and coherence were analyzed within a group of 86 allegations of children (M=10years; SD=3.7; range: 4-17) who were victims of sexual abuse. Results illustrated that age played an important role in establishing narrative coherence and predicted the level of orientation, the sequence of events and the level of evaluation of the event. Instead, PTSD was related to narrative coherence and cohesion. Therefore, in children, the narrative fragmentation could be an effective diagnostic tool for understanding the effects of PTSD. Moreover in a legal setting the traumatic effects of PTSD on the narrative coherence and cohesion could be significant indices in the evaluation of child testimony.

Abstract
The current study examined whether and which specific contents of patients' memory for cognitive therapy (CT) were associated with treatment adherence and outcome. Data were drawn from a pilot RCT of forty-eight depressed adults, who received either CT plus Memory Support Intervention (CT + Memory Support) or CT-as-usual. Patients' memory for treatment was measured using the Patient Recall Task and responses were coded into cognitive behavioral therapy (CBT) codes, such as CBT Model and Cognitive Restructuring, and non-CBT codes, such as individual coping strategies and no code. Treatment adherence was measured using therapist and patient ratings during treatment. Depression outcomes included treatment response, remission, and recurrence. Total number of CBT codes recalled was not significantly different comparing CT + Memory Support to CT-as-usual. Total CBT codes recalled were positively associated with adherence, while non-CBT codes recalled were negatively associated with adherence. Treatment responders (vs. non-responders) exhibited a significant increase in their recall of Cognitive Restructuring from session 7 to posttreatment. Greater recall of Cognitive Restructuring was marginally significantly associated with remission. Greater total number of CBT codes recalled (particularly CBT Model) was associated with non-recurrence of depression. Results highlight the important relationships between patients' memory for treatment and treatment adherence and outcome.

Abstract
OBJECTIVE To understand the meaning of trauma narration, we examined changes in the trauma narratives of youth receiving trauma-focused cognitive behavioral therapy (TF-CBT) and explored the relationship between changes in narratives and in posttraumatic stress. METHOD The sample consisted of 12 non-responders and 12 maximum-responders to treatment (M = 14.3, SD = 2.35, range = 10-17; 75% girls). The youth were assessed with the Clinical-Administered PTSD-Scale for Children and Adolescents both pre- and post-treatment. Their first and last narratives were coded according to a standardized coding manual. RESULTS For the group as a whole there was an increase in organized thoughts and reports of internal events (e.g., descriptions of thoughts and feelings), while narrative fragmentation decreased. There were no significant narrative changes in external events (e.g., descriptions of actions and dialogues). Max-responders differed significantly from non-responders in developing more organized thoughts. We did not find a significant relationship between changes in narratives and changes in posttraumatic stress symptoms (PTSS). CONCLUSIONS Youth receiving TF-CBT develop narratives that contain more organized thoughts and a greater internal focus, which are both thought to be helpful for traumatized youth. However, more coherent and organized trauma narratives were not related to reductions in PTSS. Clinical or methodological significance of this article: This study suggests that trauma-focused cognitive behavioral therapy contributes to more organized and coherent trauma narratives for traumatized youth. Although, this may be important and contribute to meaning making, therapist should be aware that this may not be sufficient in reducing posttraumatic stress symptoms in youth.

Abstract
BACKGROUND The structure of trauma narratives is considered to be related to posttraumatic stress symptomatology and thus the capacity to make a coherent narrative after stressful events is crucial for mental health. OBJECTIVE The aim of this study is to understand more of the relationship between narrative structure and posttraumatic stress symptoms (PTSS). More specifically, we investigated whether internal and external focus, organization, fragmentation, and length differed between two groups of adolescent survivors of a mass shooting, one group with low levels of PTSS and one group with high levels of PTSS. METHOD The sample comprised 30 adolescents who survived the shooting at Utøya Island in Norway in 2011. They were interviewed 4-5 months after the shooting and provided a free narrative of the event. PTSS were assessed using the UCLA Posttraumatic Stress Disorder Reaction Index (PTSD-RI). RESULTS We found that survivors with high levels of PTSS described more external events and fewer internal events in their narratives compared with survivors with low levels of symptoms. The analysis also showed that especially narratives containing more descriptions of dialogue and fewer organized thoughts were related to higher levels of PTSS. The groups did not differ in levels of narrative fragmentation or in length of the narratives. CONCLUSION Specific attributes of narrative structure proved to be related to the level of PTSS. On the basis of our results, we can recommend that practitioners focus especially on two elements of the trauma narratives, namely, the amount of external events, particularly dialogues, within the narrative and the number of organized thoughts. Participants with high levels of PTSS provided trauma narratives with low amount of organized (explanatory) thoughts accompanied by detailed descriptions of dialogues and actions, which is indicative for "here and now" quality of recall and a lack of trauma processing.

Abstract
BACKGROUND AND OBJECTIVES Empirical studies with objective measures and control conditions have failed to demonstrate disorganization; yet people tend to self-report disorganization in their trauma narratives, which may have other effects. Thus, we investigated whether a disorganized trauma memory produces more analogue PTSD symptoms and memory distortion, compared to an organized memory. METHODS Participants watched a traumatic film with missing scenes. Some saw the scenes in their correct temporal sequence; others saw a random sequence; thus for some participants we implanted a disorganized memory. We also told some participants to focus on the meaning of the event (conceptual), some on the sensory details (data-driven), and some received no instruction (control). Participants recorded their intrusions for a week. Then, they reported analogue symptoms and we tested their memory for the film and their confidence in what they remembered. RESULTS Analogue symptoms and number of reported intrusions did not differ across conditions, nor did the degree of memory distortion or confidence in those memories. However, participants who self-reported feeling more memory disorganization reported more avoidance symptoms and more memory distortion. LIMITATIONS We did not measure memory for real trauma, nor did we assess for a history of PTSD. Our results may also be restricted to temporal disorganization. CONCLUSIONS Although objective assessments of disorganization do not appear important, people's feelings regarding the disorganization of their memories not only affect their assessment of the severity of their PTSD symptoms, but also the kinds of memory errors they make.

Abstract
We examined the coherence of trauma memories in a trauma-exposed community sample of 30 adults with and 30 without posttraumatic stress disorder. The groups had similar categories of traumas and were matched on multiple factors that could affect the coherence of memories. We compared the transcribed oral trauma memories of participants with their most important and most positive memories. A comprehensive set of 28 measures of coherence including 3 ratings by the participants, 7 ratings by outside raters, and 18 computer-scored measures, provided a variety of approaches to defining and measuring coherence. A multivariate analysis of variance indicated differences in coherence among the trauma, important, and positive memories, but not between the diagnostic groups or their interaction with these memory types. Most differences were small in magnitude; in some cases, the trauma memories were more, rather than less, coherent than the control memories. Where differences existed, the results agreed with the existing literature, suggesting that factors other than the incoherence of trauma memories are most likely to be central to the maintenance of posttraumatic stress disorder and thus its treatment.

Abstract
An extensive review of both quantitative and qualitative literature reveals numerous connections between mindfulness practice and psychological well-being. Dancing Mindfulness, as a holistic wellness practice, is a creative approach to mindfulness meditation that draws on dance as the vehicle for engaging in the ancient practice characterized by non-judgment, loving kindness, and present-centered awareness. Of the first participants who learned the Dancing Mindfulness practice in a community-based setting, 10 shared their lived experience with the practice, and these experiences were analyzed using A.P. Giorgi׳s descriptive phenomenological psychological method. As a collective sample, the women described positive experiences with the Dancing Mindfulness practice. Specific themes indicated improvements in emotional and spiritual well-being, increased acceptance, positive changes to the self, and increased application of mindfulness techniques and strategies to real-world living. Another thematic area suggested that dancing and music are the two major components of action within Dancing Mindfulness leading to these benefits.

Abstract
We investigated autobiographical memory in a group of passengers onboard a trans-Atlantic flight that nearly ditched at sea. The consistency of traumatic exposure across passengers, some of whom developed post-traumatic stress disorder (PTSD), provided a unique opportunity to assess verified memory for life-threatening trauma. Using the Autobiographical Interview, which separates episodic from non-episodic details, passengers and healthy controls (HCs) recalled three events: the airline disaster (or a highly negative event for HCs), the September 11, 2001 attacks, and a non-emotional event. All passengers showed robust mnemonic enhancement for episodic details of the airline disaster. Although neither richness nor accuracy of traumatic recollection was related to PTSD, production of non-episodic details for traumatic and non-traumatic events was elevated in PTSD passengers. These findings indicate a robust mnemonic enhancement for trauma that is not specific to PTSD. Rather, PTSD is associated with altered cognitive control operations that affect autobiographical memory in general.

Abstract
Autobiographical memories of trauma victims are often described as disturbed in two ways. First, the trauma is frequently re-experienced in the form of involuntary, intrusive recollections. Second, the trauma is difficult to recall voluntarily (strategically); important parts may be totally or partially inaccessible-a feature known as dissociative amnesia. These characteristics are often mentioned by PTSD researchers and are included as PTSD symptoms in the DSM-IV-TR (American Psychiatric Association, 2000). In contrast, we show that both involuntary and voluntary recall are enhanced by emotional stress during encoding. We also show that the PTSD symptom in the diagnosis addressing dissociative amnesia, trouble remembering important aspects of the trauma is less well correlated with the remaining PTSD symptoms than the conceptual reversal of having trouble forgetting important aspects of the trauma. Our findings contradict key assumptions that have shaped PTSD research over the last 40 years.

Abstract
This study examined whether older adults recollect autobiographical memories of negative events so as to minimize unpleasant emotions to a greater extent than do younger adults. A sample of healthy older adults ( N = 126) and younger adults ( N = 119) completed the Autobiographical Memory Questionnaire and a measure of PTSD symptoms in response to their most negative recalled event. Results supported the hypothesis that older adults rated their negative memories as having: 1) less of a sense of traveling back to the time the event occurred, 2) less associated visceral emotional reactions, 3) fewer associated negative emotions, and 4) fewer PTSD symptoms, all relative to younger adults. In addition, older adults exhibited higher ratings of belief in accuracy, higher ratings that the memory comes as a coherent story, and more associated positive emotions, again all relative to younger adults. After controlling for differences between the types of events younger and older adults reported and how long ago the event occurred, the above age differences remained statistically significant, though the effect sizes were attenuated in some cases. These results are consistent in their support for the positivity effect, and suggest that older adults modify their recollections of negative events in a manner that is emotionally adaptive for them.

Abstract
Structural and content- related features of trauma narratives of traumatic events may help explain the development of PTSD. In a sample of 35 female assault survivors, we examined the association between the structure and content of trauma narratives and PTSD and other trauma-related reactions (i.e., depression, anxiety, anger, dissociation, and guilt). When controlling for recounting style and recounting distress, narrative structure was not strongly associated with PTSD or other trauma-related reactions. In contrast, the content of the trauma narratives (more positive and negative emotion words, higher cognitive process, and less self-focus being) was associated with lower symptomatology. Taken together, trauma narrative content rather than grammatical structure of the narrative may be more reflective of underlying emotional processing of the traumatic memory or lack thereof.

Abstract
The present study investigates 'folk theories' about the causes of insomnia. Participants with insomnia (n = 69) completed a qualitative and quantitative assessment of their folk theories. The qualitative assessment was to speak aloud for 1 minute in response to: 'What do you think causes your insomnia?'. The quantitative assessment involved completing the 'Causal Attributions of My Insomnia Questionnaire' (CAM-I), developed for this study. The three most common folk theories for both the causes of one's own insomnia as well as insomnia in others were 'emotions', 'thinking patterns' and 'sleep-related emotions'. Interventions targeting these factors were also perceived as most likely to be viable treatments. Seventy-five percent of the folk theories of insomnia investigated with the CAM-I were rated as more likely to be alleviated by a psychological versus a biological treatment. The results are consistent with research highlighting that folk theories are generally coherent and inform a range of judgments. Future research should focus on congruence of 'folk theories' between treatment providers and patients, as well as the role of folk theories in treatment choice, engagement, compliance and outcome.

Abstract
Intrusions are often considered the hallmark of posttraumatic stress disorder (PTSD). Despite this, relatively little is known about factors that give rise to intrusions. Cognitive models of PTSD highlight the importance of pre-existing cognitive vulnerabilities, cognitive processing and anxiety during a traumatic event, as well as negative responses to trauma sequelae. However, few studies have examined multiple forms of peritraumatic processes, and rumination in response to trauma intrusions using analogue trauma tasks, and none have examined whether broader anxious ruminative processes contribute to intrusion development. In addition, little work has investigated the role of post-state anxiety in intrusions, and anxiety may be related to both peritraumatic processing and rumination. The current study employed a distressing film paradigm to examine key tenets of cognitive models of PTSD. Ninety-one female university students completed measures of anxiety, rumination in response to anxious symptoms, peritraumatic dissociation, data driven processing, lack of self referent processing, intrusions, and rumination in response to intrusions of the distressing film. Results revealed that peritraumatic dissociation, data driven processing, and self referent processing were associated with intrusion development, with lack of self referent processing being a strong predictor of intrusion development. Post-state anxiety and rumination in response to intrusions also predicted intrusion development. Discussion focuses on implications of cognitive processes and anxiety in theories of intrusion development.

Abstract
Spontaneous encoding of the visual environment depends on the behavioral relevance of the task performed simultaneously. If participants identify target letters or auditory tones while viewing a series of briefly presented natural and urban scenes, they demonstrate effective scene recognition only when a target, but not a behaviorally irrelevant distractor, appears together with the scene. Here, we show that individuals with posttraumatic stress disorder (PTSD), who witnessed the red sludge disaster in Hungary, show the opposite pattern of performance: enhanced recognition of scenes presented together with distractors and deficient recognition of scenes presented with targets. The recognition of trauma-related and neutral scenes was not different in individuals with PTSD. We found a positive correlation between memory for scenes presented with auditory distractors and re-experiencing symptoms (memory intrusions and flashbacks). These results suggest that abnormal encoding of visual scenes at behaviorally irrelevant events might be associated with intrusive experiences by disrupting the flow of time.

Abstract
This study predicted that the quality of trauma narratives written before and following emotion-focused therapy for child abuse trauma would be positively associated with psychological disturbance before and following therapy. Narratives for 37 clients were coded for emotion words, temporal orientation, incoherence, and depth of experiencing. At pretreatment, negative emotion words and experiencing were correlated with abuse resolution, r(35) = -.36, and r(35) = -.34, respectively. At posttreatment, narrative incoherence was correlated with trauma symptoms, r(35) = .33, whereas present-future orientation and experiencing were correlated with abuse resolution, r(35) = -.37, and r(35) = -.31, respectively. Pretreatment incoherence was associated with posttreatment trauma symptoms, r(35) = .42, and pretreatment depth of experiencing was associated with posttreatment abuse resolution, r(35) = -.37. Results support narrative quality as an index of trauma disturbance.

Abstract
The current study examined cognitive-emotional distinctiveness (CED), the extent to which emotions are linked with event information, in memories associated with PTSD. Participants either with PTSD (n=68) or without PTSD (n=40) completed a modified multidimensional scaling technique to measure CED for their most negative and most positive events. The results revealed that participants in the PTSD group evidenced significantly lower levels of CED. This group difference remained significant when we limited the analysis to traumatic events that led to a PTSD diagnosis (n=33) in comparison to control participants who nominated a traumatic event that did not result in PTSD (n=32). Replicating previous findings, CED levels were higher in memories of negative events, in comparison to positive events. These results provide empirical evidence that memories associated with PTSD do contain special organizational features with respect to the links between emotions and memory. Implications for understanding and treating PTSD are discussed.

Abstract
BACKGROUND There is increasing theoretical, clinical and research evidence for the role of trauma memory in the aetiology of acute pathological stress responses in adults. However, research into the phenomenology of trauma memories in young people is currently scarce. METHODS This study compared the nature of trauma narratives to narratives of unpleasant non-traumatic events in young people (aged 8-17) who sought emergency medical attention following an assault or road traffic accident. Data were collected within 2-4 weeks of the index event. Symptom severity was assessed by child self-report and face-to-face diagnostic interviews. Comparisons of narrative indices were made between those children with acute stress disorder (ASD) and those without ASD. RESULTS Among participants (n = 50), those with ASD (38%) had significantly elevated levels of disorganisation in their trauma narrative, compared both to trauma-exposed controls and to their unpleasant comparative narrative. This effect was not accounted for by age. Regardless of ASD diagnostic status, trauma narratives had significantly higher sensory content and significantly lower positive emotion content compared to the unpleasant comparative narrative. These effects were not significant when age was included as a covariate. Acute symptom severity was significantly predicted by the level of disorganisation in the trauma narrative and the child's cognitive appraisals of the event. CONCLUSIONS These data provide the first empirical evidence that disorganisation is not only directly linked to symptom severity, but also specific to the trauma memory. In addition, it provides support for the adaptation of adult cognitive models to acute pathological stress reactions in children and adolescents.

Abstract
Participants with posttraumatic stress disorder (PTSD) and participants with a trauma but without PTSD wrote narratives of their trauma and, for comparison, of the most-important and the happiest events that occurred within a year of their trauma. They then rated these three events on coherence. Based on participants' self-ratings and on naïve-observer scorings of the participants' narratives, memories of traumas were not more incoherent than the comparison memories in participants in general or in participants with PTSD. This study comprehensively assesses narrative coherence using a full two (PTSD or not) by two (traumatic event or not) design. The results are counter to most prevalent theoretical views of memory for trauma.

Metacognition, memory disorganization and rumination in posttraumatic stress symptoms. J Anxiety Disord 2010; 24:318-25.

Abstract
The present study aimed to assess the relative contribution of memory disorganization and beliefs about trauma memory in the prediction of posttraumatic stress symptoms. A sample of 95 student nurses and midwives narrated their memory of the most distressing placement related event they had experienced. Several questionnaires were administered, including the Beliefs about Memory Questionnaire (BAMQ), which was devised for the study. Pearson's correlations, hierarchical analyses and mediation analyses were performed on the data. The reliability and validity of the BAMQ gained preliminary support. Beliefs about the trauma memory, but not memory disorganization within the trauma narrative, predicted a significant proportion of the variance in posttraumatic stress symptoms after control variables were accounted for. Consistent with the metacognitive model of PTSD, the use of rumination mediated the relationship between beliefs about the trauma memory and PTSD symptoms. The findings provide preliminary support for the role of meta-memory in the maintenance of PTSD symptoms and question the importance of memory disorganization.

Abstract
OBJECTIVE Traumatic memories are characterized by not being accessible to intentional recall nor being integrated into the matrix of autobiographical memory. Based on this description, the authors discuss the process of narration as a central means of regaining a sense of self-coherence after traumatic experiences. Formally correct narratives are characterized by three functions: orientation, reference and evaluation. Through so-called "memory talk" with socio-culturally competent partners, children learn how to reconstruct memories and to represent experience by narration. It is therefore suggested that narratives are the basic ingredient of autobiographical memory. The process of re-establishing a sense of coherence after trauma relies on the capacity for coherent narration. The latter is often not possible with traumatic experiences. METHOD AND RESULT We conducted a literature search in multiple databases for linguistic analyses of trauma narratives empirically correlating narrative style and posttraumatic psychopathology. DISCUSSION It is recommended that research in psychopathology and psychotherapy should take issues of language into account more systematically.

Abstract
This study considers the role of pre-sleep cognitive arousal, worry, and inhibition in sleep onset difficulties. The Pennebaker writing task, which promotes emotional processing by asking people to write about their thoughts, worries, and emotions, has proven effective in several areas of health. Here, the paradigm's ability to reduce pre-sleep cognitive arousal (PSCA) and sleep onset latency (SOL) in people with insomnia was tested. Twenty-eight people with insomnia were randomized to three nights of Pennebaker writing or a control condition, following a one-night baseline. The outcomes of change over baseline at Day 4 in pre-sleep cognitive arousal and SOL were compared. Writing significantly reduced pre-sleep cognitive arousal on one out of two measures, but did not significantly reduce SOL.

Abstract
We address the four main points in Monroe and Mineka (2008)'s Comment. First, we first show that the DSM PTSD diagnosis includes an etiology and that it is based on a theoretical model with a distinguished history in psychology and psychiatry. Two tenets of this theoretical model are that voluntary (strategic) recollections of the trauma are fragmented and incomplete while involuntary (spontaneous) recollections are vivid and persistent and yield privileged access to traumatic material. Second, we describe differences between our model and other cognitive models of PTSD. We argue that these other models share the same two tenets as the diagnosis and we show that these two tenets are largely unsupported by empirical evidence. Third, we counter arguments about the strength of the evidence favoring the mnemonic model, and fourth, we show that concerns about the causal role of memory in PTSD are based on views of causality that are generally inappropriate for the explanation of PTSD in the social and biological sciences.

Abstract
According to a long-standing clinical tradition, sexually traumatic experiences are processed and recalled differently from other experiences, often leading to memory impairment. In this study, we compared the characteristics of traumatic memories for sexual violence and two other types of emotional experiences. N=44 women recruited from a local sexual trauma agency were asked to recall and describe three autobiographical events: sexual abuse/assault, a non-sexual trauma, and a positive emotional event. The characteristics of the three memory types were compared on both subjective and objective measures. Further, the potential influences of level of traumatic impact and dissociation were assessed. Results indicated that memories for sexual trauma were not impaired or fragmented relative to other memories. Instead, memories for sexual trauma were associated with a remarkably high level of vividness, detail, and sensory components. Further, high levels of traumatic impact were not associated with memory impairment. Implications for the ongoing traumatic memory debate are discussed.

Abstract
Many children in war-affected and refugee populations have experienced multiple traumatic experiences, and high rates of psychologic disorders, especially posttraumatic stress disorder (PTSD), are found. Intervention strategies require pragmatic and effective approaches to treatment. This article describes the rationale for and the use of narrative exposure therapy in children (KidNET). KidNET is a short-term treatment for PTSD based on a neurocognitive theory of traumatic memory. Early treatment trials, including randomized controlled studies, show promising results for the treatment of children and adolescents who have PTSD living in war-affected countries and refugee communities.

Abstract
Cognitive-emotional distinctiveness (CED), the extent to which an individual separates emotions from an event in the cognitive representation of the event, was explored in four studies. CED was measured using a modified multidimensional scaling procedure. The first study found that lower levels of CED in memories of the September 11 terrorist attacks predicted greater frequency of intrusive thoughts about the attacks. The second study revealed that CED levels are higher in negative events, in comparison to positive events and that low CED levels in emotionally intense negative events are associated with a pattern of greater event-related distress. The third study replicated the findings from the previous study when examining CED levels in participants' memories of the 2004 Presidential election. The fourth study revealed that low CED in emotionally intense negative events is associated with worse mental health. We argue that CED is an adaptive and healthy coping feature of stressful memories.

Abstract
STUDY OBJECTIVES "Sleep quality" is poorly defined yet ubiquitously used by researchers, clinicians and patients. While poor sleep quality is a key feature of insomnia, there are few empirical investigations of sleep quality in insomnia patients. Accordingly, our aim was to investigate the subjective meaning of sleep quality among individuals with insomnia and normal sleepers. DESIGN Cross sectional between groups (insomnia vs. good sleeper). Analyses were conducted across three outcome variables: (1) a "Speak Freely" procedure in which participants' descriptions of good and poor sleep quality nights were analysed, (2) a "Sleep Quality Interview" in which participants judged the relative importance of variables included in previous research on sleep quality and (3) a sleep quality diary completed over seven consecutive nights. SETTING University Department of Psychiatry. PARTICIPANTS Individuals with insomnia (n = 25) and normal sleepers (n = 28). INTERVENTIONS N/A. RESULTS Both the insomnia and normal sleeper groups defined sleep quality by tiredness on waking and throughout the day, feeling rested and restored on waking, and the number of awakenings they experienced in the night. The insomnia group had more requirements for judging sleep to be of good quality. CONCLUSION The meaning of sleep quality among individuals with insomnia and normal sleepers was broadly similar. A comprehensive assessment of a patient's appraisal of their sleep quality may require an assessment of waking and daytime variables.

Abstract
This study tested the hypothesis that trauma memories are disjointed from other autobiographical material in posttraumatic stress disorder (PTSD). Assault survivors with (n = 25) and without PTSD (n = 49) completed an autobiographical memory retrieval task during script-driven imagery of (a) the assault and (b) an unrelated negative event. When listening to a taped imagery script of the worst moment of their assault, survivors with PTSD took longer to retrieve unrelated non-traumatic autobiographical information than those without PTSD, but not when listening to a taped script of the worst moment of another negative life event. The groups also did not differ in general retrieval latencies, neither at baseline nor after the imagery tasks. The findings are in line with suggestions that traumatic memories are less integrated with other autobiographical information in trauma survivors with PTSD than in those without PTSD.

Abstract
Ehlers and Clark [(2000). A cognitive model of post-traumatic stress disorder. Behaviour Research and Therapy, 38, 319-345] cognitive model of post-traumatic stress disorder (PTSD) has been relatively untested with children. Seventy-five children (7-16 years) were interviewed within 4 weeks of an injury that led to hospital treatment to examine whether peri-traumatic processing strategies (data-driven processing and fear) were associated with perceptions of memory quality and intrusive memories. Perceptions of memory quality mediated the relationship between data-driven processing and intrusive reactions but not avoidance, arousal or depressive reactions. Finally, the relationship between peri-event fear and intrusion reactions was mediated by perceptions of memory quality even after data-driven processing was controlled. The implications of these findings are discussed in the context of a cognitive developmental model of PTSD in children.

Abstract
Clinical theories of post-traumatic stress suggest that encoding processes at the time of a trauma are critical in determining whether intrusive memories will develop. Potential mechanisms that might influence the development of intrusive memories were studied, as was objective memory performance. In an analogue design, 65 participants were randomised to three conditions (cognitive load, hyperventilation, and control), and then watched a film of traumatic content. Intrusive memories were recorded during the experimental phase and at 1-week follow-up. Support was found for the prediction that verbal cognitive load and hyperventilation would facilitate intrusion development immediately following exposure to the trauma film; however, this was not maintained at follow-up. Consistent with cognitive models of post-traumatic stress, thought suppression and the distress associated with intrusive experiences mediated the relationship between distress caused by the film and intrusions at 1-week follow-up. Objective memory testing indicated that the three experimental groups showed similar recall and recognition performance for the content of the film; however, relative to the control group, individuals in the cognitive load condition were significantly less able to place film scenes in the correct order.

Abstract
Empirical research since the year 2000 on trauma and autobiographical memory in adults is reviewed and related to four enduring controversies in the field: Whether traumatic memories are inherently different from other types of autobiographical memory; whether memory for trauma is better or worse than memory for non-traumatic events; whether traumas can be forgotten and then recalled later in life; and whether special mechanisms such as repression or dissociation are required to account for any such forgetting. The review concludes that trauma and non-trauma memories differ substantially, but only in clinical and not in healthy populations. Whereas involuntary memory is enhanced in clinical populations, voluntary memory is likely to be fragmented, disorganised, and incomplete. Progress in experimental and neuroimaging research will depend on analysing how task performance is affected by the interaction of voluntary and involuntary memory and by individual tendencies to respond to trauma with increased arousal versus dissociation.

Abstract
This research examined the nature of children's trauma narrative themes and the relationship between these themes and concurrent and future trauma symptoms. Eighty-seven children aged 7-15 years, and their parents, participated following child exposure to a traumatic event requiring hospitalization. At 4-7 weeks post-trauma, a diagnostic interview was conducted with parents and a trauma narrative was obtained from the child. At 6 months post-trauma the diagnostic interview was re-conducted. Results provided only weak evidence of an association between dissociative trauma narrative themes and PTSD symptoms. Specifically, children who showed temporal disorganization, but not absence of emotion or dissociative amnesia, in narrative themes were more likely to report concurrent subsyndromal PTSD symptoms at 4-7 weeks post-trauma. Children who showed absence of emotion (or at least one dissociative theme) in the trauma narrative were more likely to show symptoms of hyperarousal, but not other symptoms of PTSD, at 6 months post-trauma. These findings have implications for understanding the role of dissociation and the development of PTSD in children.
