Rumination in posttraumatic stress disorder

DEPRESSION AND ANXIETY, Issue 5 2007
Tanja Michael Ph.D.
Abstract Recent studies have shown that rumination is a powerful predictor of persistent posttraumatic stress disorder (PTSD). However, to date, the mechanisms by which rumination maintains PTSD symptoms are little understood. Two studies of assault survivors, a cross-sectional (N = 81) and a 6-month prospective longitudinal study (N = 73), examined several facets of ruminative thinking to establish which aspects of rumination provide the link to PTSD. The current investigation showed that rumination is not only used as a strategy to cope with intrusive memories but it also triggers such memories. Certain characteristics of rumination, such as compulsion to continue ruminating, occurrence of unproductive thoughts, and "why" and "what if" type questions, as well as negative emotions before and after rumination, were significantly associated with PTSD, concurrently and prospectively. These characteristics explained significantly more variance in PTSD severity than the mere presence of rumination, thereby indicating that not all ways of ruminative thinking are equally maladaptive.

Posttraumatic growth in accident survivors: openness and optimism as predictors of its constructive or illusory sides

JOURNAL OF CLINICAL PSYCHOLOGY, Issue 3 2008
Tanja Zoellner
Abstract Posttraumatic growth (PTG), the phenomenon of self-reported positive outcomes of trauma, is assumed to consist of two sides: a constructive and an illusory side. This study investigates the relationship between PTG and its possible illusory and constructive predictors, as well as the moderating role of posttraumatic stress disorder (PTSD) severity. One-hundred two motor vehicle accident (MVA) survivors with full, subsyndromal, and without PTSD were assessed by multiple psychometric measures targeting PTSD severity, posttraumatic growth, optimism, and openness to experience. Hierarchical regression analysis yielded differential interaction effects between PTSD severity and optimism, as well as openness facets pointing to the moderating role of PTSD severity in the prediction of an illusory and a constructive factor in PTG. © 2008 Wiley Periodicals, Inc.

Heart rate of motor vehicle accident survivors in the emergency department, peritraumatic psychological reactions, ASD, and PTSD severity: A 6-month prospective study

JOURNAL OF TRAUMATIC STRESS, Issue 5 2006
Eric Kuhn
This small-scale study investigates the relationships between the heart rate of motor vehicle accident survivors presenting in the emergency department (ED) and acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) symptom severity. It also examines the relationships between the survivor's heart rate in the ED and peritraumatic dissociation and peritraumatic distress reported 2 weeks posttrauma. Fifty motor vehicle accident (MVA) survivors were assessed 2 weeks, 1 (N = 42), 3 (N = 37), and 6 months (N = 37) post-MVA. The heart rate in the ED predicted self-reported ASD symptom severity and clinician-rated PTSD symptom severity at 6 months but not at 1 or 3 months. Survivors' heart rate in the ED was significantly correlated with peritraumatic dissociation but not peritraumatic distress. These findings support the role of elevated ED heart rate as a predictor of both ASD and chronic PTSD symptom severity and may help to clarify the discrepant findings of previous research. [source]


Psychophysiological reactivity in female sexual abuse survivors

JOURNAL OF TRAUMATIC STRESS, Issue 4 2001
Annmarie McDonagh-Coyle
Abstract This study examined psychophysiological reactivity in 37 female childhood sexual abuse (CSA) survivors. After assessment of posttraumatic stress disorder (PTSD), psychiatric comorbidity, and trauma history, we conducted a psychophysiological assessment of forehead muscle tension, electrodermal activity, and heart rate during a mental arithmetic task and 4 script-driven imagery tasks (neutral, consensual sex, pleasant, and trauma). PTSD symptom severity correlated positively with psychophysiologic changes and negative emotions during the trauma imagery task. During mental arithmetic, PTSD symptom severity correlated negatively with autonomic changes and positively with negative emotions. These results extend earlier PTSD research showing trauma-specific increased psychophysiological reactivity related to CSA in women with PTSD. They further suggest a negative association between PTSD severity and autonomic reactions to mental arithmetic. [source]


The relationship among personality variables, exposure to traumatic events, and severity of posttraumatic stress symptoms,

JOURNAL OF TRAUMATIC STRESS, Issue 1 2001
Dean Lauterbach
Abstract In examining predictors of posttraumatic stress, researchers have focused on trauma intensity and devoted less attention to other variables. This study examined how personality and demographic variables are related to the likelihood of experiencing a trauma, and to the severity of posttraumatic symptoms in a sample of 402 college students reporting a wide range of trauma. Elevations in antisocial and borderline traits were significant predictors of retraumatization, accounting for 12% of the variance. Personality variables and trauma intensity were significant predictors of PTSD severity, accounting for 43% of the variance. Neuroticism interacted with trauma intensity in predicting Posttraumatic Stress Disorder (PTSD) severity. Among persons low in Neuroticism, there was a modest trauma intensity,PTSD relationship, whereas among persons high in neuroticism there was a strong relationship. [source]


A controlled study of imagery rehearsal for chronic nightmares in sexual assault survivors with PTSD: A preliminary report

JOURNAL OF TRAUMATIC STRESS, Issue 4 2000
Barry Krakow
Imagery-rehearsal therapy for chronic nightmares was assessed in a randomized, controlled study of sexual assault survivors with posttraumatic stress disorder (PTSD). Nightmares, sleep quality, and PTSD were assessed at baseline for 169 women, who were randomized into two groups: treatment (n = 87) and wait-list control (n = 82). Treatment consisted of two 3-hr sessions and one 1-hr session conducted over 5 weeks. Of 169 participants, 91 women (Treatment, n = 43, Control, n = 48) completed a 3-month follow-up and 78 did not. At follow-up, nightmare frequency and PTSD severity decreased and sleep quality improved in the treatment group with small to minimal changes in the control group. Treatment effects were moderate to high (Cohen's d ranged from 0.57 to 1.26). Notwithstanding the large dropout rate, imagery-rehearsal therapy is an effective treatment for chronic nightmares in sexual assault survivors with PTSD and is associated with improvement in sleep quality and decreases in PTSD severity.

Reliving, emotions, and fragmentation in the autobiographical memories of veterans diagnosed with PTSD

APPLIED COGNITIVE PSYCHOLOGY, Issue 1 2004
David C. Rubin
Fifty veterans diagnosed with posttraumatic stress disorder (PTSD) each recalled four autobiographical memories: one from the 2 years before service, one non-combat memory from the time in service, one from combat, and one from service that had often come as an intrusive memory. For each memory, they provided 21 ratings about reliving, belief, sensory properties, reexperiencing emotions, visceral emotional responses, fragmentation, and narrative coherence. We used these ratings to examine three claims about traumatic memories: a separation of cognitive and visceral aspects of emotion, an increased sense of reliving, and increased fragmentation. There was evidence for a partial separation of cognitive judgments of reexperiencing an emotion and reports of visceral symptoms of the emotion, with visceral symptoms correlating more consistently with scores on PTSD tests. Reliving, but not fragmentation of the memories, increased with increases in the trauma relatedness of the event and with increases in scores on standardized tests of PTSD severity.
