Risk factors for rape, physical assault, and posttraumatic stress disorder in women: examination of differential multivariate relationships

The National Women's Study, a 2-year, three-wave longitudinal investigation, employed a national probability sample of 3,006 adult women to: (a) identify separate risk factors for rape and physical assault, and (b) identify separate risk factors associated with post-rape posttraumatic stress disorder (PTSD) and post-physical assault PTSD. This investigation differed from previous studies in that it prospectively examined risk factors at the multivariate, as opposed to univariate level. Overall, past victimization, young age, and a diagnosis of active PTSD increased women's risk of being raped. By contrast, past victimization, minority ethnic status, active depression, and drug use were associated with increased risk of being physically assaulted. Risk factors for PTSD following rape included a history of depression, alcohol abuse, or experienced injury during the rape. However, risk factors for PTSD following physical assault included only a history of depression and lower education.     

Risk factors and outcome in ambulatory assault victims presenting to the acute emergency department setting: implications for secondary prevention studies in PTSD

Prevention of post-traumatic stress disorder (PTSD) in trauma victims is an important public health goal. Planning for the studies required to validate prevention strategies requires identification of subjects at high risk and recruitment of unbiased samples that represent the larger high-risk population (difficult because of the avoidance of many trauma victims). This study recruited high-risk victims of interpersonal violence (sexual or physical assault) presenting to an urban emergency department for prospective 1- and 3-month follow-up. Of 546 victims who were approached about participating, only 56 agreed to be contacted and only 46 participated in either the 1- or 3-month interviews. Of the 46, 43 had been previously victimized with a mean of over six traumas in the group; 21% had prior PTSD, 85% had prior psychiatric illness, and 37% had prior substance abuse. Sixty-seven percent had positive urine for alcohol or drugs on presentation. Fifty-six percent developed PTSD at 1 or 3 months with the rate declining between 1 and 3 months. There was high use of medical and psychiatric services. These findings document both the difficulty of recruiting large samples of high-risk assault victims to participate in research, and the high rate of prior traumatization, PTSD, substance use, and psychiatric morbidity in these subjects which, if still active at the time of victimization, may complicate efforts to document preventive treatment effects.     

Posttraumatic stress disorder in victims of sexual assault--related to depression or physical symptoms]

To clarify the clinical characteristics of mental disorders in sexual assault victims, we investigated the victims focusing on PTSD, depression, physical symptoms, and their relationships. SUBJECTS: Participants were 46 treatment-seeking female victims of sexual assault who consulted four hospitals, one clinic and one psychological services center, between February 2000 and April 2001. The mean +/- SD age of the participants was 28.0 +/- 8.9 years, the mean +/- SD period from the traumatic event was 94.5 +/- 88.0 months. PTSD was diagnosed and evaluated using a structured interview (Clinician-Administered PTSD Scale for DSM-IV: CAPS). Depressive symptoms were assessed using Self-rating Depression Scales (SDS). Physical symptoms were assessed using the Physical symptom scale developed by the authors. RESULTS: Thirty-two participants (69.6%) met the criteria for PTSD in their current diagnosis, and 41 (89.1%) had the disorder at some point during their lives. SDS score and Physical symptom scale score of the PTSD group were significantly higher than those scores of the non-PTSD group. The SDS score correlated with the Avoidant-numbing score. The Physical symptoms scale score correlated with the Intrusion score and Hyperarousal score. We think that the PTSD group had the co-existing depression secondary to PTSD. Although previous studies have discussed the relationship between physical symptoms and Hyperarousal symptoms, this study suggested that physical symptoms were related to Intrusion symptoms as much as Hyperarousal symptoms. We found 2 patterns when PTSD patients reported physical symptoms related to Intrusion symptoms. The patterns were caused (1) by physiological reactivity on exposure to internal or external cues that symbolize an aspect of the traumatic event, and caused (2) by somatic reenactment symptoms. CONCLUSION: We discuss the importance for clinicians to distinguish Intrusion symptoms from physical symptoms as well as Avoidant-numbing symptoms from depressive symptoms on PTSD diagnosis. Because sexual assault victims have difficulty in talking about the traumatic experience, clinicians should pay attention to these findings in developing therapeutic plans for the victims.     

PTSD in victims of sexual assault: test of a major component of the Ehlers-Clark theory

We investigated a major component of the Ehlers-Clark theory of post-traumatic stress disorder (PTSD) in a sample of 50 female victims of sexual assault. In particular, we tested the hypothesis that the victims' appraisals of the trauma and its consequences contribute significantly to the persistence of PTSD symptoms. The results indicated that the victims' appraisals of the sexual assault and its sequelae are strongly and positively related to PTSD symptoms. This finding remained significant after statistically controlling for the perceived severity of the assault. Most of the results are consistent with the Ehlers-Clark theory.     

Posttraumatic stress disorder in abused and neglected children grown up.

OBJECTIVE: The purpose of this study was to describe the extent to which childhood abuse and neglect increase a person's risk for subsequent posttraumatic stress disorder (PTSD) and to determine whether the relationship to PTSD persists despite controls for family, individual, and lifestyle characteristics associated with both childhood victimization and PTSD. METHOD: Victims of substantiated child abuse and neglect from 1967 to 1971 in a Midwestern metropolitan county area were matched on the basis of age, race, sex, and approximate family socioeconomic class with a group of nonabused and nonneglected children and followed prospectively into young adulthood. Subjects (N = 1,196) were located and administered a 2-hour interview that included the National Institute of Mental Health Diagnostic Interview Schedule to assess PTSD. RESULTS: Childhood victimization was associated with increased risk for lifetime and current PTSD. Slightly more than a third of the childhood victims of sexual abuse (37.5%), 32.7% of those physically abused, and 30.6% of victims of childhood neglect met DSM-III-R criteria for lifetime PTSD. The relationship between childhood victimization and number of PTSD symptoms persisted despite the introduction of covariates associated with risk for both. CONCLUSIONS: Victims of child abuse (sexual and physical) and neglect are at increased risk for developing PTSD, but childhood victimization is not a sufficient condition. Family, individual, and lifestyle variables also place individuals at risk and contribute to the symptoms of PTSD.     

Changes in cortisol and dehydroepiandrosterone in women victims of physical and psychological intimate partner violence.

BACKGROUND: Although intimate partner violence (IPV) has a great impact on women's health, few studies have assessed the consequences on physiologic responses. METHODS: Women abused by their intimate male partners either physically (n = 70) or psychologically (n = 46) were compared with nonabused control women (n = 46). Information about sociodemographic characteristics, smoking, pharmacologic treatment, lifetime history of victimization (childhood and adulthood), and mental health status (depression, anxiety, and posttraumatic stress disorder, PTSD) was obtained through structured interviews. Saliva samples were collected at 8 am and 8 pm for 4 consecutive days to determine morning and evening basal levels of cortisol and dehydroepiandrosterone (DHEA). RESULTS: Women who were victims of IPV had more severe symptoms of depression, anxiety, and incidence of PTSD and higher levels of evening cortisol and morning and evening DHEA compared with control women. Intimate partner violence was the main factor predicting the alterations in hormonal levels after controlling for age, smoking, pharmacologic treatment, and lifetime history of victimization. Mental health status did not have a mediating effect on the impact of IPV on hormonal levels. CONCLUSIONS: This study shows that both physical and psychological IPV have a significant impact on the endocrine systems of women.     

Gender differences in violence exposure and violence risk among adolescent inpatients

Gender-specific rates of violence exposure and violence perpetration among psychiatrically ill adolescents has received little scientific attention. We examined 130 adolescent inpatients and found no difference between male and female subjects with respect to self-reported violence potential or actual violence perpetration. Female inpatients, however, were significantly more often victims of sexual assault, and male inpatients were significantly more often victims of physical assault. For male inpatients, a history of violence perpetration in one area was closely linked with a history of violence victimization in the same area. Alternatively, patterns of victimization and perpetration among female inpatients were less predictable and had crossover to victimization and perpetration experiences in other areas. Correlational analyses revealed that violence risk was associated with a broad range of internalizing and externalizing psychopathology. Significant associations with hopelessness, suicidality, and childhood trauma differentiated the violence risk of male and female inpatients. We propose a hypothesis for understanding these differences and conclude that although psychiatrically ill adolescent male and female patients may commonly fall victim to differing forms of violence, both genders are at equal risk for actual violence perpetration.     

Posttraumatic stress disorder symptoms influence health status of deployed peacekeepers and nondeployed military personnel

Posttraumatic stress disorder (PTSD) is associated with depression and alcohol abuse. PTSD symptoms also contribute to poor health among military veterans. The aim of the present study was to test models pertaining to the direct and indirect influences of PTSD symptoms on the health status of deployed and sociodemographically comparable nondeployed military personnel. Participants were 1,187 deployed male peacekeepers and 669 nondeployed male military personnel who completed a battery of questionnaires, including measures of PTSD symptoms, depression, alcohol use, and general health status. Structural equation modeling was used to test predictions regarding the direct and indirect influences of PTSD symptoms on health status. Results indicate that PTSD symptoms have a direct influence on health, regardless of deployment status. PTSD symptoms also indirectly promote poorer health through influence on depression, but not alcohol use, in deployed and nondeployed peacekeepers. Increased alcohol use did not contribute to poorer health beyond the contribution of PTSD symptoms alone. Future research directions are discussed.     

Panic following trauma: the etiology of acute posttraumatic arousal

Two studies examined the contributing factors for panic symptoms following trauma. In Study 1, survivors of sexual and nonsexual assaults (N=105) were assessed at 2 weeks postcrime. Prior trauma, psychiatric history, crime characteristics, and peritraumatic dissociation were assessed. Posttraumatic panic was modestly predicted by childhood sexual abuse (CSA) experiences, a history of Anxiety and Depression, and peritraumatic dissociation. Childhood physical abuse (CPA), Adult Victimization, crime variables, and a prior history of Substance Use disorders and posttraumatic stress disorder (PTSD) were not implicated. In Study 2, the role of peritraumatic panic in predicting later arousal was also examined in a similar sample who were assessed within 6 weeks of their trauma (N=93). Presence of significant arousal during trauma predicted frequency of posttrauma panic attacks, but not its severity. In contrast to Study 1, prior history of PTSD, perception of life threat, and the index trauma being a sexual assault all predicted posttrauma panic, whereas prior trauma exposure and depression did not. These findings are discussed in terms of cognitive and arousal factors that may influence posttrauma panic.     

The relationship between sexual assault, religiosity, and mental health among male veterans

OBJECTIVES: We examine the association between sexual assault, religion and mental health among male veterans. METHODS: We used longitudinal data collected from 2,427 male veterans who received VA outpatient care. Sexual assault was self-reported in the questionnaire. Two dimensions of religiosity were used: organizational (frequency of religious service attendance) and subjective religiosity (the extent that religious beliefs are a source of strength or comfort). Mental health was measured by the mental component summary from the Veterans SF-36 and depression was measured by the Center for Epidemiologic Studies-Depression scale. A regression model that uses the generalized estimating equation approach for longitudinal repeated data analysis was used. RESULTS: Based on the baseline data, 96 (4%) patients reported ever experiencing sexual assault. These patients have significantly lower levels of mental health status and higher levels of depression (p < .001). The regression results show that this decrement in mental health and increment in depression associated with sexual assault are in lesser degrees for patients who attended religious service more frequently compared to those who never did (p < .05). Similarly, there is a smaller magnitude of increment in depression associated with sexual assault for those who have a higher level of subjective religiosity (p < .05). CONCLUSIONS: Although the prevalence of self reported sexual assault is low among male veterans, those who reported sexual assault experiences had lower levels of mental health status and higher levels of depression. Further, religion attenuates this association which highlights the important role religion might have in coping with this stressful life event.     

Posttraumatic Growth in Treatment-seeking Female Assault Victims

The importance of measuring growth outcomes following a traumatic event has been highlighted in recent literature (e.g., Linley, Joseph: Journal of Traumatic Stress 17:11–21, 2004). Although reports of growth are abundant, the relationship between growth outcomes and post-trauma distress remains unclear, with studies yielding conflicting results regarding this relationship. The purpose of the present study was to explore the interrelationships among growth outcomes and measures of depression and posttraumatic stress disorder (PTSD) among 100 female treatment-seeking physical and sexual assault victims. Although the majority of women reported some degree of growth in this study, and growth scores were comparable to those from other samples, measures of depression and PTSD were not significantly related to growth scores. The implication of these findings and future direction for research are discussed.     

Potential risk factors for rape in three ethnic groups

This article describes the frequency of possible risk factors that emerged during a cross-cultural study of psychosocial response to sexual assault among African-American, Hispanic, and non-Hispanic white women presenting for treatment at a major urban rape treatment center. Of 881 victims screened, 51% had no observable risk factors while 49% fell into categories of variables that previous research has associated with increased vulnerability. Included were mental disability (psychiatric or developmental), a prior history of rape or incest, tourist or visitor status (site unfamiliarity), and homelessness. Ethnic groups differed significantly in these categories, suggesting socioeconomic and cultural variables that may affect rape statistics and that should be taken into account in rape prevention programs in the community.     

Positive emotion dysregulation and posttraumatic stress disorder symptoms: Investigating the role of anxiety sensitivity

ObjectivePosttraumatic stress disorder (PTSD) symptoms are prevalent and deleterious among individuals who have experienced a sexual assault. Although an emerging field of research has established a link between positive emotion dysregulation and PTSD symptoms, there is a limited understanding of mechanisms underlying this relation. Individuals who have experienced a sexual assault may begin to fear any arousal-related sensations via stimulus generalization, including that associated with positive emotions, which, in turn, may amplify PTSD symptoms. Thus, the current study examined the role of anxiety sensitivity in the association between positive emotion dysregulation and PTSD symptoms.MethodsA sample of 500 community members reporting a history of sexual assault (M_age = 34.54, 54.4% male, 79.0% white) completed measures of positive emotion dysregulation, anxiety sensitivity, and PTSD symptoms.ResultsFindings detected a significant indirect effect of anxiety sensitivity in the relation between positive emotion dysregulation and PTSD symptoms (β = 0.28, SE = 0.03, 95% CI [0.22, 0.34]). Supplementary analyses revealed that effects held for subscales of anxiety sensitivity (i.e., cognitive, physical, social concerns) and PTSD symptom clusters (i.e., intrusions, avoidance, negative alternations in cognitions and mood, alternations in arousal and reactivity).ConclusionsThis study offers preliminary empirical support for the assertion that fear of arousal-related sensations associated with positive emotions may partially explain the link between positive emotion dysregulation and PTSD symptoms among those who have experienced a sexual assault. Information from this study could advance future research and treatment.     

Psychopathology of sexual abuse in young people with intellectual disability

The present study addressed two issues using a sample of child and adolescent victims and perpetrators of sexual abuse: (1) the extent of post‐traumatic stress disorder (PTSD) in the sample; and (2) the possible distinction between perpetrators whose motivations were sexually impulsive, and those who were controlling and abuse‐reactive. Retrospective case material from 43 cases (21 victims only, and 22 perpetrators, of whom 16 were also victims) provided the data. Post‐traumatic symptomatology was not common. Only one case of PTSD was found. Perpetrators could be distinguished by whether they had suffered sexual abuse alone, sexual and physical abuse, or neither. The proposed distinction between perpetrators received support. Sexual abuse directed at younger victims was associated with earlier experience of multiple forms of abuse. The present data does not support the view that post‐traumatic symptoms following victimization are a mediator of sexual abuse perpetration. It is argued that an elaboration of the Williams & New developmental model of perpetration better fits the data.     

Two International Conferences

Sexual violence can cause acute and persistent negative psychological outcomes among children and adults in a community. Previous studies have frequently reported high prevalence of prior child and adolescent sexual abuse among adult victims of sexual violence. This raises uncertainty over the specific contribution of sexual victimization in adulthood to the adverse psychological outcomes. The present study draws on a large nationally representative sample of adults without history of childhood sexual abuse, and applies diagnostic criteria of DSM-IV, in order to investigate the risk factors and psychiatric comorbidities correlated with sexual victimization in adulthood. In a large representative sample of U.S. adults without history of childhood sexual abuse, 2.5% reported sexual victimization in adulthood. Female gender, living alone, economic disadvantage, and a history of childhood adversities and parental psychopathology were identified as risk factors. Adult sexual victimization increased the risk of developing a variety of psychiatric disorders, especially PTSD (HR = 3.43, 95% CI [2.67, 4.41]) and drug abuse (HR = 3.38, 95% CI [2.49, 4.58]). Conversely, pre-existing psychiatric psychopathology, particularly PTSD (HR = 3.99, 95% CI [2.68, 5.94]) and dysthymia (HR = 2.26, 95% CI [1.42, 3.59]), increased the likelihood of sexual victimization in adulthood. Childhood experience and adulthood sociodemographic characteristics are important in affecting the risk of being sexually victimized in adulthood. Psychiatric disorders can act as both risk factors and outcomes of adult sexual victimization.     

Psychotic experiences in the context of depression: The cumulative role of victimization

Previous studies have reported an association between depression and psychotic experiences, but little is known about what drives this co-occurrence. This study tests the hypothesis that exposure to trauma and bullying may strengthen the relation between depression and psychotic experiences. A total of 799 college students completed self-report questionnaires on psychotic experiences, depression, bullying, and sexual trauma. Hierarchical linear regression analyses were conducted to test the direct relationship between depression and psychotic experiences, as well as interactions. Approximately 20% of respondents reported a history of being bullied, and 7% reported exposure to childhood sexual trauma. There was a significant direct relationship between depression and psychotic experiences. The association between depression and psychotic experiences was significantly stronger among respondents who were victims of both bullying and sexual violence compared to those who experienced either exposure alone, or who were not exposed to either form of victimization. These findings suggest that cumulative exposure to trauma and victimization may contribute to the co-occurrence of depression and psychotic experiences. History of victimization should be assessed among individuals with depressive symptoms to improve treatment plans and outcomes.     

An open-label trial of evidence-based cognitive behavior therapy for nightmares and insomnia in crime victims with PTSD.

OBJECTIVE: Insomnia and nightmares are perceived as secondary phenomena in posttraumatic stress disorder (PTSD). Scant treatment research has targeted these two sleep disturbances. This study reports on an open-label trial of cognitive behavior therapy for insomnia and disturbing dreams in crime victims with PTSD. The relationship among nightmares, sleep disturbances, and PTSD symptoms is discussed. METHOD: Sixty-two participants completed a 10-hour group treatment consisting of imagery rehearsal for nightmares and sleep hygiene, stimulus control, and sleep restriction for insomnia. Nightmare frequency, sleep quality, sleep impairment, and ratings for PTSD, anxiety, and depression symptoms were assessed at baseline and at the 3-month follow-up. RESULTS: All measures demonstrated improvement that was roughly equivalent to changes in clinical severity from severe to moderate for sleep quality, sleep impairment, and nightmare frequency, from borderline severe to borderline moderate for PTSD symptoms, and from extremely severe to borderline severe for anxiety and depression symptoms. CONCLUSIONS: In this uncontrolled study, successful treatment for insomnia and nightmares in crime victims was associated with improvement in symptoms of PTSD, anxiety, and depression. Participants with clinical improvements in PTSD symptoms demonstrated significantly greater improvement in sleep quality and nightmare frequency than those whose PTSD symptoms did not improve.     

Posttraumatic stress disorder, dissociation, and sexual abuse history in epileptic and nonepileptic seizure patients

Rates of posttraumatic stress disorder (PTSD), dissociative symptoms, and childhood sexual abuse (CSA) are believed to be higher among patients with nonepileptic seizures (NES) than those with epileptic seizures (ES). However, women have higher rates of CSA and sexual assault than men. Comparisons of seizure type controlling for gender may produce different results. Data from an opportunity sample of 34 patients with ES and 17 with NES evaluated during or following phase 1 video-EEG monitoring demonstrated that patients with NES had statistically higher rates of PTSD and CSA and higher Dissociative Experiences Scale (DES) scores than patients with ES. No differences were found between women with NES and ES for histories of PTSD or CSA. Mean between-group DES score differences remained. Results indicated that PTSD, dissociation, and CSA may be common among women presenting to a tertiary epilepsy referral center for both ES and NES. Neither a positive history of CSA nor a history of PTSD was evidence against epilepsy.     

Psychological intimate partner violence: the major predictor of posttraumatic stress disorder in abused women

Intimate partner violence (IPV) significantly impacts women mental and physical wellbeing and therefore represents a worldwide public health problem. A clear association between IPV and increased risk to develop posttraumatic stress disorder (PTSD) has been documented. However, few studies examined how different features of IPV (physical, psychological, sexual) interact with other traumatic stress experiences (physical, psychological and sexual childhood abuse and adulthood victimization by other/s than the partner) in determining PTSD. Women abused by the partner (n=75) were compared with non-abused control women (n=52). Information about sociodemographic profile and relevant personal characteristics was obtained through structured interviews. A comprehensive questionnaire was designed for a face-to-face interview in order to obtain detailed information about duration and frequency of the different types of violent acts above mentioned. The incidence and severity of symptoms of current PTSD were assessed with Echeburua's Severity of Symptom Scale of Posttraumatic Stress Disorder, a structured interview based on DSM-IV criteria. Women suffering from IPV had a significantly higher rate of PTSD symptomatology as compared to control women, whereas childhood abuse variables did not explain PTSD score variance. In addition, the severity of IPV was significantly and positively correlated with the intensity of PTSD symptoms. Women involved in an abusive relationship were more frequently exposed to other experiences of adulthood victimization, suggesting that their higher PTSD vulnerability could be a result of cumulative traumatic experiences. A relevant result of the correlation analysis was the strong, positive association between PTSD and each different type of IPV. In particular, the psychological component of intimate partner violence was the strongest predictor of posttraumatic stress disorder. This study underlines the importance of separating the effects of the different types of intimate partner abuse when taking into account its effects on women mental health.     

Injury severity,prior trauma history,urinary cortisol levels,and acute PTSD in motor vehicle accident victims

This study examined the relationship between prior history of traumatic events, life threat, and injury severity experienced during a motor vehicle accident (MVA), and posttraumatic stress disorder (PTSD) assessed 1 month after the accident. In addition, initial urinary cortisol levels after the accident were examined as a possible mediator of this relationship. Fifteen-hour urinary cortisol samples were collected from MVA victims upon admission to the trauma unit. In the hospital, subjective life threat was measured and objective Injury Severity Scores (ISSs) were computed. One month after the accident, participants were assessed for prior history of traumatic experiences, presence of acute PTSD, and levels of intrusive and avoidant thoughts and behaviors. Victims, who met PTSD diagnostic criteria, reported more prior traumatic events, and significantly greater life threat despite receiving significantly lower ISSs than victims who did not develop PTSD. The relationships between ISSs and PTSD symptoms and prior trauma history and PTSD symptoms were mediated by cortisol levels. Results suggest that cortisol levels in the acute aftermath of a traumatic event may serve as a mechanism through which various factors may increase risk for PTSD.
