Obsessive Compulsive Symptoms Predict Posttraumatic Growth: A Longitudinal Study

Although posttraumatic growth (PTG) has received growing attention, the relationship between PTG and distress remains unclear. This longitudinal study examines the relationship between posttraumatic obsessive-compulsive (OC) symptoms and PTG. Israeli veterans were followed over 17 years using self-report questionnaires of OC symptoms, posttraumatic stress disorder (PTSD), and PTG. Hierarchical regression analyses demonstrated that OC symptoms predicted PTG, even when initial PTG levels and PTSD symptoms were controlled for in the combatants group. These preliminary findings suggest that OC symptoms may play an important role in facilitating psychological growth. Future research is warranted to explore the mechanisms responsible for this relationship.     

Narrative exposure therapy for posttraumatic stress disorder in tortured refugees: A preliminary uncontrolled trial

Halvorsen, J.Ø. & Stenmark, H. (2010). Narrative exposure therapy for posttraumatic stress disorder in tortured refugees: A preliminary uncontrolled trial. Scandinavian Journal of Psychology 51, 495–502. Torture has severe mental health effects, especially in terms of posttraumatic stress disorder (PTSD) and depression. However, there is still a lack of empirical treatment studies. The present paper presents data on 16 torture survivors receiving 10 sessions of narrative exposure therapy (NET). Symptoms of PTSD and depression, assessed by Clinician‐Administered PTSD Scale (CAPS) and Hamilton Rating Scale for Depression (HRSD), decreased significantly from pre‐treatment to 6‐month follow‐up, with Cohen’s d effect sizes of 1.16 and 0.84, respectively. Although treatment gains were moderate, further research on evidence‐based treatments for PTSD and depression in refugee torture survivors is warranted.     

小学生创伤后应激障碍对攻击行为的影响：应对方式的调节作用

采用儿童创伤后应激障碍症状量表、儿童行为问题核查表和应对方式问卷,考察汶川地震极重灾区980名小学生的创伤后应激障碍、应对方式与攻击行为的关系。结果表明：地震后1年半,灾区小学生攻击行为水平较低,但男生的攻击行为明显高于女生;积极认知在回避性症状对攻击行为的预测中起显著的负向调节作用;负向发泄分别在回避性症状和警觉增高症状对攻击行为的预测中起显著的正向调节作用。     

Crisis Support and Coping as Mediators of Well-Being in Persons with Spinal Cord Lesion

This study aims to investigate whether crisis support and coping mediate symptoms of posttraumatic stress disorder (PTSD) in individuals with spinal cord lesions (SCL). PTSD, crisis support, and coping were assessed an average of 83 days after the injury (T1), at discharge from the rehabilitation center (T2), and an average of 121 days following discharge (T3). Sixty-nine newly injured paraplegics and tetraplegics completed the questionnaire at T1, 40 (58%) at T2, and 38 (55%) at T3. Individuals with PTSD experienced significantly lower levels of social support, and used more emotional coping than did those without PTSD. On the basis of logistic regression analyses, emotional coping and the interaction between negative response and emotional coping predicted PTSD. Emotional coping is a strong predictor of PTSD in persons with new SCL.     

Anxiety sensitivity and posttraumatic stress among traumatic event-exposed youth

Total and factor scores of the Childhood Anxiety Sensitivity Index (CASI) were examined in relation to posttraumatic stress symptom levels within a community-based sample of 68 (43 females) traumatic event-exposed youth between the ages of 10 and 17 years (M_age=14.74 years). Findings were consistent with hypotheses; global anxiety sensitivity (AS) levels, as well as disease, unsteady, and mental incapacitation concerns, related positively to posttraumatic stress levels, whereas social concerns were unrelated to symptom levels. These results suggest that fears of the physical and mental consequences of anxiety are associated with relatively higher levels of posttraumatic stress subsequent to traumatic event exposure. Findings are discussed in terms of potential implications for the role of AS in developmentally sensitive etiological models of posttraumatic stress disorder (PTSD).     

Development and Validation of the Screen for Adolescent Violence Exposure (SAVE)

Empirical evidence was provided on the utility of the Screen for Adolescent Violence Exposure (SAVE) in assessing adolescent exposure to school, home, and community violence. The SAVE was empirically developed on 1,250 inner-city adolescents, and obtained excellent reliability and validity. Both exploratory and confirmatory factor analyses identified three factors: Traumatic Violence, Indirect Violence, and Physical/Verbal Abuse. The SAVE demonstrated utility in classifying high- and low-violence participants, and correlated significantly with both objective crime data and theoretically relevant constructs (anger, posttraumatic stress symptoms, and internalizing/externalizing problems). Thus, the SAVE provides measurement of the stressor criterion associated with posttraumatic stress disorder, and allows quantification of severity of violence exposure by setting.     

Exposure Therapy Beliefs and Utilization for Treatment of PTSD: A Survey of Licensed Mental Health Providers

Exposure-based therapies for posttraumatic stress disorder (PTSD) and anxiety disorders remain underutilized, despite their effectiveness and widescale dissemination efforts. This study surveyed a broad range of licensed providers (N = 155) to examine rates at which prolonged exposure (PE) and other interventions are used to treat PTSD and to investigate provider characteristics linked to exposure beliefs and utilization. While 92.3% of clinicians reported understanding of or training in exposure, only 55.5% of providers reported use of PE to treat PTSD. Clinicians with current cognitive behavioral therapy (CBT) orientation, CBT training orientation, a doctoral degree, and training in PE endorsed greater likelihood of exposure utilization for PTSD (ps < .001, ds = 0.82–1.98) and less negative beliefs about exposure (ps < .01, ds = 0.55–2.00). Exposure beliefs also differed based on healthcare setting (p < .001). Among providers trained in exposure (n = 106), master’s degree and non-CBT current theoretical orientation were associated with high utilization yet also negative beliefs. Results suggest exposure training, accurate beliefs, and utilization still lag among some groups of providers. Additionally, negative beliefs and misunderstanding of the exposure rationale may persist even among providers who are trained and report high utilization.     

Posttraumatic Stress Disorder and Chronic Pain Arising from Motor Vehicle Accidents: Efficacy of Interoceptive Exposure Plus Trauma-Related Exposure Therapy

Preliminary data are presented on the pattern of treatment response of combining interoceptive exposure (IE) with trauma-related exposure therapy (TRE) in five female patients with posttraumatic stress disorder (PTSD) and comorbid chronic musculoskeletal pain originating from motor vehicle accidents. Treatment consisted of four sessions of IE followed by eight sessions of TRE. Four participants reported a reduction in PTSD symptoms after completing treatment, and three no longer met diagnostic criteria for PTSD. Although both interventions were associated with reductions in PTSD symptoms, TRE was associated with greater reductions in PTSD symptoms than IE and was particularly effective at reducing avoidance. IE was associated with larger reductions in anxiety sensitivity than TRE. Pain symptoms lessened slightly during IE and then worsened following TRE. Anxiety decreased after completing treatment, whereas panic and depressive symptoms responded less so. Three individuals completed a 3-month follow-up assessment. There was no change in their PTSD diagnostic status, and all experienced a slight loss of pre–post gains, particularly involving the return of pain. Clinical and research implications are discussed.     

BDNF serum levels in subjects developing or not post-traumatic stress disorder after trauma exposure

Post-traumatic stress disorder (PTSD) is a syndrome resulting from exposure to a severe traumatic event that poses threatened death or injury and produces intense fear and helplessness. The neural structures implicated in PTSD development belong to the limbic system, an important region for emotional processing. Brain-derived neurotrophic factor (BDNF) is a neurotrophin that serves as survival factor for selected populations of central nervous system (CNS) neurons and plays a role in the limbic system by regulating synaptic plasticity, memory processes and behavior. Impaired BDNF production in the brain can lead to a variety of CNS dysfunctions including symptoms associated with PTSD. However, so far fewer studies have investigated this neurotrophin in patients with PTSD. Furthermore, given the multiple role of BDNF in various CNS disorders, it cannot be excluded that traumatic events per se may influence neurotrophin levels, without a direct association to the PTSD syndrome.     

The Struggle of Behavioral Therapists With Exposure: Self-Reported Practicability,Negative Beliefs,and Therapist Distress About Exposure-Based Interventions

Exposure-based interventions are a core ingredient of evidence-based cognitive-behavioral treatment (CBT) for anxiety disorders, posttraumatic stress disorder (PTSD), and obsessive-compulsive disorder (OCD). However, previous research has documented that exposure is rarely utilized in routine care, highlighting an ongoing lack of dissemination. The present study examined barriers for the dissemination of exposure from the perspective of behavioral psychotherapists working in outpatient routine care (N = 684). A postal survey assessed three categories of barriers: (a) practicability of exposure-based intervention in an outpatient private practice setting, (b) negative beliefs about exposure, and (c) therapist distress related to the use of exposure. In addition, self-reported competence to conduct exposure for different anxiety disorders, PTSD, and OCD was assessed. High rates of agreement were found for single barriers within each of the three categories (e.g., unpredictable time management, risk of uncompensated absence of the patient, risk of decompensation of the patient, superficial effectiveness, or exposure being very strenuous for the therapist). Separately, average agreement to each category negatively correlated with self-reported utilization of exposure to a moderate degree (-.35 ≤ r ≤ -.27). In a multiple regression model, only average agreement to barriers of practicability and negative beliefs were significantly associated with utilization rates. Findings illustrate that a multilevel approach targeting individual, practical, and systemic barriers is necessary to optimize the dissemination of exposure-based interventions. Dissemination efforts may therefore benefit from incorporating strategies such as modifying negative beliefs, adaptive stress management for therapists, or increasing practicability of exposure-based interventions.     

Recovering the context in posttraumatic stress disorder: The psychosocial trauma in victims of political violence and terrorism

Abstract

Throughout history, humans have frequently carried out harmful actions against one another. Often, these actions result in intensive and long lasting pain and suffering. Posttraumatic stress disorder (PTSD) diagnosis has been the theoretical tool used mostly by psychologists to understand the physical, emotional and behavioural symptoms following a traumatic experience. Due to its clinical and medical roots, PTSD diagnosis represents man in a social vacuum, a man without context, and a model of health closely tied to illness. The aim of the paper is to reintroduce the social context of human beings into trauma diagnosis, and to develop a health model that is more focused on well-being than on illness. Both points of view help us to seek a theoretical way for better understanding the psychosocial trauma that result from political violence and terrorism. Psychosocial trauma has definite roots, and destroys our inner world—the world of our most valuable meanings—infects our minds with hate against others, and breaks the social fabric we belong to.     

Is Acoustic Startle a Viable Exposure Protocol for Posttraumatic Stress Disorder? A Clinical Case Study

Exaggerated startle is a common symptom (based on Diagnostic and Statistical Manual of Mental Disorders [fourth edition] Criterion D) for many patients with posttraumatic stress disorder (PTSD). Findings from previous studies suggest that exaggerated startle may be due to trauma exposure or pretrauma vulnerability factors for PTSD development. The present clinical case study reports on a patient with PTSD characterized by a very prominent startle response and preference against standard trauma-related exposure strategies. On the basis of recent findings that interoceptive exposure exercises (e.g. shaking head side to side, hyperventilation) elicit trauma-related memories (Wald & Taylor, 2008), the authors sought to determine whether repeated application of an acoustic startle stimulus would serve to diminish the prominent startle response and facilitate exposure and overall symptom reduction by eliciting trauma-related memories. The protocol was successful in eliciting vivid and distressing trauma-related memories. Over the course of seven exposure trials, the patient demonstrated a decrease in distress elicited during the protocol, improved mood, and reduced general anxiety and trauma-related distress. He also reported significantly decreased startle response to loud noises encountered during activities of daily living. Although preliminary, these finding suggest that the acoustic startle protocol may be a viable (interoceptive) exposure strategy for individuals with PTSD, particularly those with exaggerated startle responses and those who are not amenable to standard trauma-related exposure strategies.     

Interactive effects of cumulative lifetime traumatic brain injuries and combat exposure on posttraumatic stress among deployed military personnel

Growing research links Traumatic Brain Injury (TBI) with greater posttraumatic stress disorder (PTSD) symptoms. Much of this research has focused on the influence of the presence or severity of a single TBI while neglecting the potential cumulative effects of multiple TBIs incurred across an individual’s lifetime on combat-related PTSD. The present study addressed this gap using a sample of 157 military service members and 4 civilian contractors who underwent structured TBI interviews at a military hospital in Iraq and completed the Combat Experiences Scale (CES) and Posttraumatic Checklist – Military (PCL-M). Results indicated that a greater number of lifetime TBIs were associated with greater PTSD symptoms when accounting for the presence and severity of a recent, deployment-related TBI. Additionally, a significant interaction of number of lifetime TBIs and combat exposure emerged, indicating that exposure to combat yielded greater PTSD symptoms among those with multiple lifetime TBIs compared to those with one or zero lifetime TBIs. These data suggest that incurring multiple TBIs may amplify the link between combat exposure and PTSD and underscore the need to screen for lifetime TBI history.
