The long-term sequelae of sexual abuse: support for a complex posttraumatic stress disorder

International Trauma Questionnaire and Posttraumatic Cognitions Inventory-9: validity evidence and measurement invariance of their Brazilian versions

BACKGROUND

The International Trauma Questionnaire (ITQ) is used to measure posttraumatic stress disorder (PTSD) and complex posttraumatic stress disorder (CPTSD) symptoms, and the Posttraumatic Cognitions Inventory-9 (PTCI-9) is used to measure posttraumatic cognitions. Both tools have been translated for use in Brazil. However, the psychometric properties of the Brazilian versions were not investigated, and no study has verified the invariance of these tools for many traumatic event types.

OBJECTIVE

This study examined the validity, reliability, and measurement invariance of the Brazilian versions of the ITQ and the PTCI-9 for trauma type, gender, race, age group, education level, and geographical region.

METHODS

A total of 2,111 people (67.74% women) participated in an online survey. The scale models were tested via confirmatory factor analyses and measurement invariance through multigroup analyses. Pearson's correlation analyses were used to examine the relationships between PTSD, CPTSD, posttraumatic cognitions, and depressive symptoms.

RESULTS

Except for the affective dysregulation factor, the reliabilities of the ITQ and PTCI-9 dimensions were adequate. Models with six correlated dimensions for the ITQ and three correlated dimensions for the PTCI-9 showed adequate fit to the data. The ITQ and PTCI-9 exhibited scalar invariance for gender, race, age group, education level, and geographical region. The ITQ also demonstrated full invariance for trauma type. The factors of both instruments were related to each other and to depressive symptoms, with higher effect sizes for posttraumatic cognitions and complex posttraumatic stress disorder symptoms.

CONCLUSION

We recommend using the Brazilian versions of the ITQ and PTCI-9, which are crucial tools for assessing and treating trauma-related disorders.

Correlates of resilience after childhood sexual abuse among men who have sex with men

Men who have sex with men (MSM) are at high risk for physical and mental health conditions and are often discussed in the health literature as "at risk" versus "at promise". However, there is an ongoing need to examine factors that place MSM "at promise" for optimal well-being. This manuscript examines correlates of resilience, the ability to "bounce back" and function adaptively after adversities, among MSM. One hundred and five MSM with a history of childhood sexual abuse, who were enrolled in a randomized control trial were recruited for a supplemental study assessing resilience and other psychosocial factors. Participants completed measures assessing resilient trait and coping (i.e. "I am able to adapt" and "I tend to bounce back"), symptoms of trauma, trauma-related thoughts, and distress tolerance (ability to regulate unpleasant feelings). Findings from multivariable linear regressions controlling for covariates (age, education, race/ethnicity, and income) indicated that higher resilience was associated with (a) lower trauma scores on reexperiencing severity (b = -1.41, SE = .53, p = .01) and avoidance severity (b = -1.61, SE= .67, p = .02), (b) lower post-traumatic cognitions (b = -11.39, SE = 5.08, p = .03) especially negative cognitions about the self (b = -.44, SE = .16, p = .007), and (c) higher distress tolerance (b = .26, SE = .10, p = .01). Our preliminary findings suggest that resilient coping/traits are important to research after childhood sexual abuse among MSM, potentially assess in clinical settings, and address in interventions.

Sex Disparities in Adverse Childhood Experiences and HIV/STIs: Mediation of Psychopathology and Sexual Behaviors

HIV and other sexually transmitted infections (STIs) are important public health challenges in the US. Adverse childhood experiences (ACEs), including abuse (emotional, physical or sexual), witnessing violence among household members, may have an effect on sexual behaviors, which increase the risk of HIV/STIs. The aim of this study was to examine the sex differences in the role of posttraumatic stress disorder (PTSD), major depression (MD), substance use disorders (SUDs), early sexual debut, and intimate partner violence (IPV) perpetration as mediators in the association between ACEs and HIV/STIs. Data were obtained from Wave 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions. Structural equation modeling was used to determine the role of PTSD, MD, SUDs, early sexual debut, and IPV perpetration as mediators in the relationships between ACEs and HIV/STIs. Differences and similarities existed in the mediational roles of psychopathology and sexual behaviors. For example, among men, MD fully mediated physical/psychological abuse (β = 0.0002; p = 0.012) and sexual abuse (β = 0.0002; p = 0.006), and HIV/STIs while among women, MD fully mediated physical/psychological abuse (β = 0.0005; p < 0.001) and parental violence (β = -0.0002; p = 0.012). Among men, IPV perpetration fully mediated sexual abuse (β = -0.0005; p = 0.012) and HIV/STIs while among women, IPV perpetration was not a statistically significant mediator. HIV/STI prevention and intervention programs should use a life course approach by addressing adverse childhood events among men and women and consider the sex differences in the roles of psychopathology and sexual behaviors.

The Moderating Effect of State Anger on Treatment Outcome in Female Adolescents With PTSD

Trauma experienced in childhood and adolescence negatively affects the development of adaptive regulation of emotions and is associated with greater symptoms of anger. Prior research has suggested that high levels of anger may impede the outcome of treatment in adults with posttraumatic stress disorder (PTSD). The current study investigated whether high levels of anger resulted in poorer treatment outcomes in adolescent girls with PTSD. Participants included 61 female adolescent survivors of sexual abuse or assault who were randomized to either prolonged exposure for adolescents (PE-A) or client-centered therapy (CCT) for traumatized children for 8-14 weekly sessions. Participants were followed for 12 months posttreatment. High levels of state anger at baseline were associated with less improvement in PTSD symptoms in the CCT group than the PE-A group (d = 0.62). The moderating effects of state anger on improvement in PTSD symptoms was significant with emotion regulation difficulties, which may underlie anger symptoms (d = 0.58) in the model. The results of this study suggessted that high state anger was less of an impediment to treatment of PTSD for those receiving PE-A than those receiving less differentiated approaches such as CCT.

Developmentally adapted cognitive processing therapy for adolescents suffering from posttraumatic stress disorder after childhood sexual or physical abuse: a pilot study

Although childhood sexual abuse and childhood physical abuse (CSA and CPA) have severe psychopathological consequences, there is little evidence supporting psychotherapeutic interventions for adolescents who have experienced CSA or CPA. To provide a treatment tailored to the specific needs of adolescents suffering from abuse-related posttraumatic stress disorder (PTSD), we modified Cognitive Processing Therapy (CPT) by adding new treatment modules and changing the therapy setting. To evaluate the feasibility and efficacy of Developmentally Adapted CPT (D-CPT), we treated 12 adolescents suffering from PTSD secondary to CSA or CPA. Patients were assessed prior to treatment (t0), post-treatment (t1), and 6 weeks after treatment (t2). Assessments included the Clinician-Administered PTSD Scale (CAPS), the UCLA PTSD Index (UCLA), the Children's Depression Inventory (CDI), the Adolescent Dissociative Experiences Scale (A-DES), and the Borderline Symptom List (BSL-23). MANOVAs revealed that posttraumatic stress measurements and associated symptom measurements significantly differed across time points. When comparing t0 with t2, Cohen's d was large with respect to the CAPS scores (d = 1.45, p < .001) and the UCLA scores (d = 1.91, p < .001). Cohen's d had a medium magnitude with respect to the CDI scores (d = .78, p < .001), the A-DES scores (d = 0.64, p < .05), and the BSL-23 scores (d = 0.74, p < .01). D-CPT has the potential to reduce PTSD symptoms and comorbid psychopathology in adolescents with histories of CSA or CPA.

An Investigation of Depression, Trauma History, and Symptom Severity in Individuals Enrolled in a Treatment Trial for Chronic PTSD

OBJECTIVE

To explore how factors such as major depressive disorder (MDD) and trauma history, including the presence of childhood abuse, influence diverse clinical outcomes such as severity and functioning in a sample with posttraumatic stress disorder (PTSD).

METHOD

In this study, 200 men and women seeking treatment for chronic PTSD in a clinical trial were assessed for trauma history and MDD and compared on symptom severity, psychosocial functioning, dissociation, treatment history, and extent of diagnostic co-occurrence.

RESULTS

Overall, childhood abuse did not consistently predict clinical severity. However, co-occurring MDD, and to a lesser extent a high level of trauma exposure, did predict greater severity, worse functioning, greater dissociation, more extensive treatment history, and additional co-occurring disorders.

CONCLUSION

These findings suggest that presence of co-occurring depression may be a more critical marker of severity and impairment than history of childhood abuse or repeated trauma exposure. Furthermore, they emphasize the importance of assessing MDD and its effect on treatment seeking and treatment response for those with PTSD.

Biological correlates of complex posttraumatic stress disorder-state of research and future directions

Complex posttraumatic stress disorder (PTSD) presents with clinical features of full or partial PTSD (re-experiencing a traumatic event, avoiding reminders of the event, and a state of hyperarousal) together with symptoms from three additional clusters (problems in emotional regulation, negative self-concept, and problems in interpersonal relations). Complex PTSD is proposed as a new diagnostic entity in ICD-11 and typically occurs after prolonged and complex trauma. Here we shortly review current knowledge regarding the biological correlates of complex PTSD and compare it to the relevant findings in PTSD. Recent studies provide support to the validity of complex PTSD as a separate diagnostic entity; however, data regarding the biological basis of the disorder are still very limited at this time. Further studies focused on complex PTSD biological correlates and replication of the initial findings are needed, including neuroimaging, neurobiochemical, genetic, and epigenetic investigations. Identification of altered biological pathways in complex PTSD may be critical to further understand the pathophysiology and optimize treatment strategies.

Self-reported sleep disturbances in patients with dissociative identity disorder and post-traumatic stress disorder and how they relate to cognitive failures and fantasy proneness

Sleep disturbances, fantasy proneness, cognitive failures, and dissociative symptoms are related to each other. However, the co-occurrence of these phenomena has been primarily studied in non-clinical samples. We investigated the correlations between these phenomena in dissociative identity disorder (DID) patients, post-traumatic stress disorder (PTSD) patients, and healthy controls. Both patient groups reported more sleep problems and lower sleep quality and displayed higher levels of fantasy proneness and cognitive failures than controls. However, the two patient groups did not differ with regard to these variables. Moreover, a higher level of unusual sleep experiences tended to predict participants belonging to the DID group, while specifically a lower sleep quality and more cognitive failures tended to predict participants belonging to the PTSD group.

The relationship between sexual trauma, peritraumatic dissociation, posttraumatic stress disorder, and HIV-related health in HIV-positive men

This study tested a novel extension of P. P. Schnurr and B. L. Green's (2004) model of the relationships between trauma symptoms and health outcomes with specific application to HIV-positive men. A diverse sample of 167 HIV-positive men recruited from San Francisco Bay Area HIV clinics completed demographic, medical, trauma history, and symptom questionnaires. Mediation analyses were conducted using the method proposed by R. Baron and D. Kenny (1986). Regression analyses found that sexual revictimization (SR) significantly mediated the relationship between child sexual abuse and peritraumatic dissociation (PD), and PD mediated the relationship between SR and current posttraumatic stress (PTS) symptom severity. PTS symptoms partially mediated the relationship between SR and current HIV symptom severity. The findings indicate that among HIV-positive men, sexually revictimized men constitute a vulnerable group that is prone to PD, which places them at risk for posttraumatic stress disorder (PTSD) and worsened HIV-related health. Furthermore, traumatic stress symptoms were associated with worse HIV-related symptoms, suggesting that PTS symptoms mediate the link between trauma and health outcomes. This study highlights the need for future research to identify the biobehavioral mediators of the PTSD-health relationship in HIV-positive individuals.

Evidence-based treatment for adult women with child abuse-related Complex PTSD: a quantitative review

INTRODUCTION

Effective first-line treatments for posttraumatic stress disorder (PTSD) are well established, but their generalizability to child abuse (CA)-related Complex PTSD is largely unknown.

METHOD

A quantitative review of the literature was performed, identifying seven studies, with treatments specifically targeting CA-related PTSD or Complex PTSD, which were meta-analyzed, including variables such as effect size, drop-out, recovery, and improvement rates.

RESULTS

Only six studies with one or more cognitive behavior therapy (CBT) treatment conditions and one with a present centered therapy condition could be meta-analyzed. RESULTS indicate that CA-related PTSD patients profit with large effect sizes and modest recovery and improvement rates. Treatments which include exposure showed greater effect sizes especially in completers' analyses, although no differential results were found in recovery and improvement rates. However, results in the subgroup of CA-related Complex PTSD studies were least favorable. Within the Complex PTSD subgroup, no superior effect size was found for exposure, and affect management resulted in more favorable recovery and improvement rates and less drop-out, as compared to exposure, especially in intention-to-treat analyses.

CONCLUSION

Limited evidence suggests that predominantly CBT treatments are effective, but do not suffice to achieve satisfactory end states, especially in Complex PTSD populations. Moreover, we propose that future research should focus on direct comparisons between types of treatment for Complex PTSD patients, thereby increasing generalizability of results.

An evaluation of ICD-11 PTSD and complex PTSD criteria in a sample of adult survivors of childhood institutional abuse

BACKGROUND

The WHO recently launched the proposal for the 11th version of the International Classification of Diseases (ICD-11) that also includes two diagnoses related to traumatic stress. In contrast to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), ICD-11 will probably, in addition to posttraumatic stress disorder (PTSD), also define a new diagnosis termed "complex posttraumatic stress disorder" (CPTSD).

OBJECTIVE

We aimed to apply the proposed ICD-11 criteria for PTSD and CPTSD and to compare their prevalence to the ICD-10 (International Classification of Diseases [10th revision]) PTSD prevalence. In addition, we compiled a list of symptoms for CPTSD based on subthreshold PTSD so as to include a wider group of individuals.

METHODS

To evaluate the appropriateness of the WHO ICD-11 proposal compared to the criteria of ICD-10, we applied the newly introduced criteria for PTSD and CPTSD deriving from the Posttraumatic Stress Disorder Checklist - Civilian Version (PCL-C) and the Brief Symptom Inventory (BSI) scales, to a sample of adult survivors (N=229) of childhood institutional abuse. We evaluated the construct validity of CPTSD using confirmatory factor analysis (CFA).

RESULTS

More individuals fulfilled the criteria for PTSD according to ICD-10 (52.8%) than the ICD-11 proposal (17% for PTSD only; 38.4% if combined with complex PTSD). The new version of PTSD neutralized the gender effects. The prevalence of CPTSD was 21.4%, and women had a significantly higher rate of CPTSD than men (40.4 and 15.8%, respectively). Those survivors who were diagnosed with CPTSD experienced institutional abuse for a longer time. CFA showed a strong model fit.

CONCLUSION

CPTSD is a highly relevant classification for individuals with complex trauma history, but surprisingly, effects of gender were apparent. Further research should thus address gender effects.

Alexithymia associated with nightmare distress in idiopathic REM sleep behavior disorder

STUDY OBJECTIVES

Idiopathic REM sleep behavior disorder (iRBD) is characterized by atypical REM sleep motor activity, vivid dreams and nightmares, and dream-enacting behaviors that can result in injuries to the patient and bed partner. It is also a known predictor of Parkinson disease (PD). Alexithymia has been associated with disturbances in sleep and dreaming (e.g., nightmares) and is a non-motor symptom of PD. We assessed alexithymia and disturbed dreaming in iRBD patients with the aim of determining if these two factors are elevated and interrelated among this population.

DESIGN

Questionnaire study of clinically diagnosed patients.

SETTING

Clinical sleep disorders center.

PATIENTS OR PARTICIPANTS

Thirty-two iRBD patients and 30 healthy age- and sex-matched control participants.

MEASUREMENTS AND RESULTS

Participants completed the 20-item Toronto Alexithymia Scale (TAS-20), the Dream Questionnaire, and the Beck Depression Inventory. iRBD patients obtained higher TAS-20 total scores (62.16 ± 13.90) than did controls (52.84 ± 7.62; F 1,59 = 10.44, P < 0.01), even when controlling for depressive symptoms, and more frequently attained the suggested cutoff for alexithymia than did controls (P < 0.01). iRBD patients obtained higher scores on the Difficulty Identifying Feelings alexithymia subscale. For both iRBD and control groups, the Difficulty Indentifying Feelings subscale correlated positively with the Nightmare Distress scale of the Dream Questionnaire.

CONCLUSIONS

Elevated alexithymia scores among idiopathic rapid eye movement sleep behavior disorder patients, and especially a difficulty in identifying feelings, parallels evidence of dysautonomia in this population. The higher incidence of distressing nightmares and the association of nightmares with alexithymia further extend similar findings for both clinical and non-clinical samples and suggest that an affect regulation disturbance may be common to the two sets of symptoms.

Increased anterior cingulate cortex and hippocampus activation in Complex PTSD during encoding of negative words

Post-traumatic stress disorder (PTSD) is associated with impaired memory performance coupled with functional changes in brain areas involved in declarative memory and emotion regulation. It is not yet clear how symptom severity and comorbidity affect neurocognitive functioning in PTSD. We performed a functional magnetic resonance imaging (fMRI) study with an emotional declarative memory task in 28 Complex PTSD patients with comorbid depressive and personality disorders, and 21 healthy non-trauma-exposed controls. In Complex PTSD patients--compared to controls--encoding of later remembered negative words vs baseline was associated with increased blood oxygenation level dependent (BOLD) response in the left ventral anterior cingulate cortex (ACC) and dorsal ACC extending to the dorsomedial prefrontal cortex (dmPFC) together with a trend for increased left hippocampus activation. Patients tended to commit more False Alarms to negative words compared to controls, which was associated with enhanced left ventrolateral prefrontal and orbitofrontal cortex (vlPFC/OFC) responses. Severity of child abuse was positively correlated with left ventral ACC activity and severity of depression with (para) hippocampal and ventral ACC activity. Presented results demonstrate functional abnormalities in Complex PTSD in the frontolimbic brain circuit also implicated in fear conditioning models, but generally in the opposite direction, which may be explained by severity of the trauma and severity of comorbid depression in Complex PTSD.

Understanding factors associated with early therapeutic alliance in PTSD treatment: adherence, childhood sexual abuse history, and social support

OBJECTIVE

Therapeutic alliance has been associated with better treatment engagement, better adherence, and less dropout across various treatments and disorders. In treatment of posttraumatic stress disorder (PTSD), it may be particularly important to establish a strong early alliance to facilitate treatment adherence. However, factors such as childhood sexual abuse (CSA) history and poor social support may impede the development of early alliance in those receiving PTSD treatment. We sought to examine treatment adherence, CSA history, and social support as factors associated with early alliance in individuals with chronic PTSD who were receiving either prolonged exposure therapy (PE) or sertraline.

METHOD

At pretreatment, participants (76.6% female; 64.9% Caucasian; mean age = 37.1 years, SD = 11.3) completed measures of trauma history, general support (Inventory of Socially Supportive Behaviors), and trauma-related social support (Social Reactions Questionnaire). Over the course of 10 weeks of PE or sertraline, they completed early therapeutic alliance (Working Alliance Inventory) and treatment adherence measures.

RESULTS

Early alliance was associated with PE adherence (r = .32, p < .05) and overall treatment completion (r = .19, p < .05). Only trauma-related social support predicted the strength of early alliance beyond the effects of treatment condition (β = .23, p < .05); CSA history was not predictive of a lower early alliance.

CONCLUSIONS

Given the associations with adherence, clinicians may find it useful to routinely assess alliance early in treatment. Positive trauma support, not CSA history, may be particularly important in the development of a strong early therapeutic alliance.

Posttraumatic stress disorder, cardiovascular, and metabolic disease: a review of the evidence

BACKGROUND

Posttraumatic stress disorder (PTSD) is a significant risk factor for cardiovascular and metabolic disease.

PURPOSE

The purpose of the current review is to evaluate the evidence suggesting that PTSD increases cardiovascular and metabolic risk factors, and to identify possible biomarkers and psychosocial characteristics and behavioral variables that are associated with these outcomes.

METHODS

A systematic literature search in the period of 2002-2009 for PTSD, cardiovascular disease, and metabolic disease was conducted.

RESULTS

The literature search yielded 78 studies on PTSD and cardiovascular/metabolic disease and biomarkers.

CONCLUSIONS

Although the available literature suggests an association of PTSD with cardiovascular disease and biomarkers, further research must consider potential confounds, incorporate longitudinal designs, and conduct careful PTSD assessments in diverse samples to address gaps in the research literature. Research on metabolic disease and biomarkers suggests an association with PTSD, but has not progressed as far as the cardiovascular research.

Fear conditioning and early life vulnerabilities: two distinct pathways of emotional dysregulation and brain dysfunction in PTSD

The newly proposed criteria for posttraumatic stress disorder (PTSD) in the Diagnostic and Statistical Manual (DSM-V) include dysregulation of a variety of emotional states including fear, anger, guilt, and shame, in addition to dissociation and numbing. Consistent with these revisions, we postulate two models of emotion dysregulation in PTSD in which fear is not the prevailing emotion but is only one of several components implicated in a dysregulated emotional system that also mediates problems regulating anger, guilt, shame, dissociation, and numbing.We discuss whether there is a relationship between fear and other emotion regulation systems that may help further our understanding of PTSD and its underlying neurocircuitry. Two pathways describing the relationship between fear and other emotion regulation systems in PTSD are proposed. The first pathway describes emotion dysregulation as an outcome of fear conditioning through stress sensitization and kindling. The second pathway views emotion dysregulation as a distal vulnerability factor and hypothesizes a further exacerbation of fear and other emotion regulatory problems, including the development of PTSD after exposure to one or several traumatic event(s) later in life. Future research and treatment implications are discussed.

Long-term physical health consequences of childhood sexual abuse: a meta-analytic review

OBJECTIVE

The purpose of the present article was to systematically review the literature investigating the long-term physical health consequences of childhood sexual abuse (CSA).

METHODS

Literature searches yielded 31 studies comparing individuals with and without a history of CSA on six health outcomes: general health, gastrointestinal (GI) health, gynecologic or reproductive health, pain, cardiopulmonary symptoms, and obesity. Exploratory subgroup analyses were conducted to identify potential methodological moderators.

RESULTS

Results suggested that a history of CSA was associated with small to moderate group differences on almost all health outcomes assessed, such that individuals with a history of CSA reported more complaints for each health outcome. Suggestive trends in moderating variables of study design and methodology are presented.

CONCLUSIONS

Results highlight the long-term physical health consequences of CSA and identify potential moderators to aid in the design of future research.

Sexual abuse and sexual risk behavior: beyond the impact of psychiatric problems

OBJECTIVE

This study examined the association between sexual abuse (SA) and sex risk in girls and boys placed in alternative and therapeutic school settings while controlling for psychiatric problems.

METHOD

Adolescents were recruited from alternative and therapeutic schools. Youth completed audio computer-assisted self-interviews assessing childhood abuse, sexual behaviors, sexual attitudes, and psychiatric symptoms.

RESULTS

Of the 162 youth with available data, 23% reported a moderate or severe SA history. After controlling for gender and the presence of a psychiatric diagnosis, youth with a SA history were significantly more likely to have engaged in sex, had sex in the last 90 days, and engaged in unprotected sex. Adolescents with a history of SA also endorsed fewer advantages of using condoms.

CONCLUSIONS

SA is uniquely associated with sexual behavior and attitudes even when adjusting for the presence of a psychiatric diagnosis. These data have implications for interventions for those with SA histories.

Trait dissociation predicts posttraumatic stress disorder symptoms in a prospective study of urban police officers

The current study prospectively examines the predictive relationship of trait dissociation, assessed during academy training, to PTSD symptoms assessed at 12 months of active police duty in relatively young and healthy police academy recruits (N = 180). The roles of pre-academy trauma exposure, exposure to life-threatening critical incidents during police duty, and peritraumatic dissociation at the time of the officer's worst critical incident were also examined. Utilizing path analytic techniques, greater trait dissociation, assessed during academy training, was predictive of both peritraumatic dissociation, and PTSD symptoms assessed at 12 months of police service. Moreover, after accounting for trait dissociation and peritraumatic dissociation, the relationship of previous trauma to later PTSD symptoms was no longer significant, demonstrating that the effect of previous trauma on later vulnerability to PTSD symptoms in this sample may be mediated by both trait and peritraumatic dissociation.

Hostility and anomie: links to preterm delivery subtypes and ambulatory blood pressure at mid-pregnancy

Underlying maternal vascular disease has been implicated as one of several pathways contributing to preterm delivery (PTD) and psychosocial factors such as hostility, anomie, effortful coping, and mastery may be associated with PTD by affecting maternal vascular health. Using data from the Pregnancy Outcomes and Community Health (POUCH) study, we included 2018 non-Hispanic White and 743 African American women from 52 clinics in five Michigan, USA communities. Women were interviewed at 15-27 weeks' gestation and followed to delivery. We found that relations between psychosocial factors and PTD subtypes (i.e. medically indicated, premature rupture of membranes, spontaneous labor) varied by race/ethnicity and socio-economic position (Medicaid insurance status). Among African American women not insured by Medicaid, anomie levels in mid-pregnancy were positively associated with medically indicated PTD after adjusting for maternal age and education. Among all women not insured by Medicaid, hostility levels were positively associated with spontaneous PTD after adjusting for maternal race/ethnicity, age, and education. Failure to detect links between psychosocial factors and PTD risk in poorer women may be due to their excess risk in multiple PTD pathways and/or a more complex web of contributing risk factors. In a subset of 395 women monitored for blood pressure, anomie scores were positively associated with systolic blood pressure and heart rate and hostility scores were positively associated with systolic and diastolic blood pressure, heart rate and mean arterial pressure in models that included time, awake/asleep, race/ethnicity, and age as covariates. Further adjustment for body mass index and smoking attenuated the anomie-vascular relations but had little effect on the hostility-vascular relations. Overall this study of pregnant women provides some physiologic evidence to support findings linking levels of anomie and hostility with risk of PTD.

Hypothalamic-pituitary-adrenal axis function in dissociative disorders, post-traumatic stress disorder, and healthy volunteers

BACKGROUND

This study investigated basal and stress-induced hypothalamic-pituitary-adrenal (HPA)-axis alterations in dissociative disorders (DDs).

METHODS

Forty-six subjects with DD without lifetime post-traumatic stress disorder (PTSD), 35 subjects with PTSD, and 58 healthy comparison (HC) subjects, free of current major depression, were studied as inpatients. After a 24-hour urine collection and hourly blood sampling for ambient cortisol determination, a low-dose dexamethasone suppression test was administered, followed by the Trier Social Stress Test.

RESULTS

The DD group had significantly elevated urinary cortisol compared with the HC group, which was more pronounced in the absence of lifetime major depression, whereas the PTSD and HC groups did not differ. The DD group demonstrated significantly greater resistance to, and faster escape from, dexamethasone suppression compared with the HC group, whereas the PTSD and HC groups did not differ. The three groups did not differ in cortisol stress reactivity, but both psychiatric groups demonstrated a significant inverse correlation between dissociation severity and cortisol reactivity, after controlling for all other symptomatology. The PTSD subgroup with comorbid DD tended to have blunted stress reactivity compared with the HC group.

CONCLUSIONS

The study demonstrates a distinct pattern of HPA-axis dysregulation in DDs, emphasizing the importance of further study of stress-response systems in dissociative psychopathology.

Internalizing and externalizing subtypes in female sexual assault survivors: implications for the understanding of complex PTSD

This study replicated and extended findings of internalizing and externalizing subtypes of posttraumatic psychopathology (Miller, M. W., Greif, J. L., & Smith, A. A. (2003). Multidimensional Personality Questionnaire profiles of veterans with traumatic combat exposure: Internalizing and externalizing subtypes. Psychological Assessment, 15, 205-215; Miller, M. W., Kaloupek, D. G., Dillon, A. L., & Keane, T.M. (2004). Externalizing and internalizing subtypes of combat-related PTSD: A replication and extension using the PSY-5 Scales. Journal of Abnormal Psychology, 113, 636-645) to a female sample of rape survivors with chronic PTSD. Cluster analyses of Schedule for Nonadaptive and Adaptive Personality (Clark, L. A. (1996). SNAP-Schedule for Nonadaptive and Adaptive Personality: Manual for administration, scoring, and interpretation. Minneapolis: University of Minnesota Press.) temperament scale profiles from 143 women with PTSD partitioned the sample into a simple PTSD cluster, defined by normal range personality scores and moderate symptomatology, and 2 more "complex" clusters distinguished by more severe tendencies towards externalizing or internalizing psychopathology. Externalizers were characterized by disinhibition, substance dependence, and Cluster B personality disorder features; internalizers by low positive temperament, high rates of major depressive disorder, and elevations on measures of schizoid and avoidant personality disorder.

Unresolved attachment, PTSD, and dissociation in women with childhood abuse histories

The primary objective of this study was to examine unresolved trauma as assessed by the Adult Attachment Interview and current psychiatric symptoms, focusing on posttraumatic stress disorder (PTSD) and dissociation, in a group of adult female childhood abuse survivors. The authors examined psychiatric symptoms and attachment representations in a group with (n = 30) and without (n = 30) abuse-related PTSD. The findings revealed that unresolved trauma carried a 7.5-fold increase in the likelihood of being diagnosed with PTSD and was most strongly associated with PTSD avoidant symptoms rather than dissociative symptoms. The utility of a PTSD framework for understanding unresolved trauma and the role of intentional avoidance of trauma cues in the maintenance of traumatized states of mind are discussed.

Posttraumatic stress disorder part II: development of the construct within the North American psychiatric taxonomy

TOPIC

The impairment associated with posttraumatic stress disorder (PTSD) carries with it staggering costs to the individual, to the family, and to society as a whole. Although there is strong evidence that gender plays a significant role in responses to stress and trauma, gender specificity is still not well incorporated into clinical or research work in the area of PTSD.

PURPOSE

This is the second of three articles examining the sufficiency of the current PTSD construct to articulate the full spectrum of human responses to trauma. This article chronicles ongoing refinements to the original PTSD criteria and the subsequent controversies.

SOURCE OF INFORMATION

Existing bodies of theoretical and research literature related to the effects of trauma.

CONCLUSION

In a third article we will review evidence supporting the existence of a more complex posttraumatic stress reaction associated with interpersonal trauma (physical/sexual abuse/assault).

Is traumatic stress a vulnerability factor for women with substance use disorders?

The primary goal of this paper is to review existing findings from trauma, addictions and developmental research in order to delineate salient and outstanding questions for future research in this field. Toward this aim, our manuscript will provide an overview of the extant body of knowledge of trauma/PTSD comorbidity with substance use disorders and draw attention to converging developmental and neurobiological literature on the consequences of trauma on self-regulation. We conclude with suggestions for future research in these areas.

[Diagnostic and clinical aspects of complex post-traumatic stress disorder]

The symptomatology of patients suffering in the aftermath of severe and prolonged traumatization is not entirely covered by the diagnostic criteria of post-traumatic stress disorder (PTSD). Consequently, the concept of complex PTSD was proposed, including symptoms of affective dysregulation, dissociation and somatization, alterations in self-perception, altered relationships with others, and altered systems of meaning. Thereby, a variety of symptoms usually classified as co-morbid disorders are combined in a single etiological model. The whole symptomatology is considered as more or less effective adaptation strategies and not primarily as deficits. This understand-ing of the underlying etiology in subjects with complex traumatization opens perspectives for new psychotherapeutic treatment strategies which have already shown effectiveness in daily practice.

Therapeutic Alliance, Negative Mood Regulation, and Treatment Outcome in Child Abuse-Related Posttraumatic Stress Disorder

This study examined the related contributions of the therapeutic alliance and negative mood regulation to the outcome of a 2-phase treatment for childhood abuse-related posttraumatic stress disorder (PTSD). Phase 1 focused on stabilization and preparatory skills building, whereas Phase 2 was comprised primarily of imaginal exposure to traumatic memories. Hierarchical regression analyses indicated the strength of the therapeutic alliance established early in treatment reliably predicted improvement in PTSD symptoms at posttreatment. Furthermore, this relationship was mediated by participants' improved capacity to regulate negative mood states in the context of Phase 2 exposure therapy. In the treatment of childhood abuse-related PTSD, the therapeutic alliance and the mediating influence of emotion regulation capacity appear to have significant roles in successful outcome.

BEREAVEMENT BY TRAUMATIC MEANS: THE COMPLEX SYNERGY OF TRAUMA AND GRIEF

When people lose intimates unexpectedly, in particular from malicious acts of violence, they are at risk for chronic grief reactions. The phenomenology, clinical symptoms, clinical needs, and risk factors associated with loss by traumatic means and the combined influences of loss and trauma exposure are yet to be systematically studied. We review the complex interplay between trauma and loss by traumatic means. The distinctions between normal and traumatic loss, and complicated and traumatic grief, are contrasted with the traditional conceptualization of posttraumatic stress disorder. The role of various mediators such as concurrent or life-span trauma exposure and interpersonal factors, particularly the degree of attachment to the individual or group traumatically lost, is discussed. We offer a more integrated and focused view of traumatic grief, its predictors, and future directions for the integrative study of trauma and loss outcomes.

The impact of perceived child physical and sexual abuse history on Native American women's psychological well-being and AIDS risk

The impact of perceived child abuse history on 160 adult, Native American women's emotional well-being (i.e., depressive mood and anger) and AIDS risk was examined. How sense of mastery and social support might lead to women's greater resiliency was also investigated. Child physical-emotional abuse was found to have greater impact on depressive mood and anger and AIDS risk than did child sexual abuse. This finding was independent of current stress in women's lives. Women who were physically-emotionally abused as children had 5.14 times greater odds of having a sexually transmitted disease in their lifetimes than did women who experienced only marginal or no physical-emotional abuse. Moreover, consistent with the communal culture of Native Americans, social support was found to contribute more to resilience than sense mastery did. Reasons for the greater predictive power of child physical-emotional abuse compared with child sexual abuse in a growing number of studies are discussed.
