Are There Racial Differences in the Experience of Harmful or Traumatic Events within Psychiatric Settings?

The current study examined racial differences in the reported frequency and distress associated with potentially harmful or traumatic experiences occurring within psychiatric settings. One hundred and forty-two (109 African-American; 32 Caucasian) randomly selected adult consumers recruited from a community psychosocial day program completed a battery of self-report measures to assess experiences in the psychiatric setting, lifetime trauma exposure, PTSD severity, and were the subject of a chart review. A subset of participants (20%) also completed a qualitative interview exploring their perceptions of events occurring in psychiatric settings. Few racial differences were noted in the reported frequency or distress associated with particular events in the psychiatric setting. However, we found differential patterns of association between adverse psychiatric events and lifetime trauma history, and racial differences in diagnosis and medications prescribed by the mental health center. These racial differences merit further attention to better understand their meaning and to improve mental health services provided to both African-Americans and Caucasian public-sector psychiatric patients.     

Trauma exposure and post-traumatic stress disorder in the general population

OBJECTIVE: To examine the lifetime prevalence of trauma experiences and post-traumatic stress disorder (PTSD). METHOD: Questionnaire-assessed PTSD, the type of traumatic event experienced, perceived trauma impact, and trauma frequency in 1824 randomly selected men and women. RESULTS: PTSD lifetime prevalence was estimated at 5.6% with a 1 : 2 male-to-female ratio, in spite of men reporting greater trauma exposure. The highest PTSD risk was associated with sexual and physical assault, robbery and multiple trauma experiences. Controlling for trauma type did not account for gender differences, while controlling for experienced distress did. CONCLUSION: The conditional probability for PTSD varied as a function of trauma type, frequency and impact of the event, with increased rates associated with prevalent trauma exposure and higher perceived distress. The latter accounted for the gender effect, suggesting that gender differences in PTSD in part represent a generally greater vulnerability to stress in women.     

Trauma and Posttraumatic Stress Disorder in Primary Care Patients

BACKGROUND: This article examines the nature of psychological trauma and posttraumatic stress disorder (PTSD) in 504 patients recruited from primary care settings. METHOD: Patients were screened for anxiety in waiting rooms at 14 general medical settings, and those with a sufficient number and severity of anxiety symptoms were administered a standardized diagnostic clinical interview. Those who met DSM-IV criteria for an anxiety disorder and who were willing to participate were included in this study. Of the 504 patients, 185 met DSM-IV criteria for PTSD. RESULTS: Results indicated that 418 (83%) of primary care patients in our sample reported at least 1 traumatic event in their lifetime. The most prevalent traumas experienced by the entire sample of participants were witnessing others being seriously injured or killed, serious accidents, and rape. Of those participants with PTSD, rape was the strongest predictor of a PTSD diagnosis. Analyses examining gender differences indicated that, for women, a history of other unwanted sexual contact or witnessing a sexual assault, being attacked with a weapon or with intent to kill, or witnessing someone being injured were found to be risk factors for a PTSD diagnosis. Examination of clinical characteristics indicated a high rate of comorbidity of psychiatric disorders among patients with PTSD, including high rates of alcohol/substance abuse, depression, and suicide attempts. CONCLUSION: These findings emphasize the continued need to assess patients presenting at general medical facilities about trauma history.     

Relationship between symptom over-reporting and pre- and post-combat trauma history in veterans evaluated for PTSD

We examined the prevalence of pre- and post-combat traumatic events in the histories of 129 combat veterans referred to be evaluated for PTSD and examined the impact of these non-combat traumatic events on self-reported psychiatric symptoms. Participants were consecutive referrals to a Veterans Affairs outpatient post-traumatic stress disorder (PTSD) clinic who completed structured interviews, self-report measures (e.g., Minnesota Multiphasic Personality Inventory-2; MMPI-2), and a trauma history questionnaire as part of their routine clinical evaluations. Findings show that non-combat trauma was prevalent in this sample, with 65% (21% pre-combat) reporting physical assaults and 12% (11% pre-combat) reporting sexual assaults. Overall, history of sexual or physical assaults did not appear to be systematically related to reported symptom level. However, chi square analyses revealed a consistent over-representation of veterans who reported sexual trauma in the category suggestive of response exaggeration (i.e., MMPI-2 F-K validity index > or = 13). Finally, a hierarchical regression equation predicting F-K scores was computed, but accounted for only 15.9% of the variance in F-K. Presence of sexual assault history was the only predictor associated with a more pronounced response set suggestive of exaggeration or deception. These findings tentatively indicate that if history of sexual or physical assault has an impact on symptom reporting in combat veterans evaluated for PTSD, it is of modest magnitude.     

Mental health effects of adolescent trauma exposure in a female college sample: exploring differential outcomes based on experiences of unique trauma types and dimensions

Most studies on the psychological impact of trauma exposure focus on the response to a single type of trauma, with little or no attention paid to the contribution of prior traumatic experiences. The goal of this study was to disentangle some of the confounding effects of multiple trauma exposures by exploring the unique contribution to mental health outcomes made by specific types and dimensions of trauma. This report compares the psychological outcomes of college women who experienced different types of trauma during adolescence, including traumatic bereavement, sexual assault, and physical assault. Young women who had experienced a single event of one of these types were compared with peers who had experienced multiple single events, ongoing sexual and/or physical abuse, as well as those who had experienced no trauma. Results, based on structured clinical interviews, and self-report measures showed that there were some significant differences in mental health outcomes based on trauma type. However, trauma exposure versus no exposure and the cumulative effects of exposure versus one-time experiences played the key roles in differentiating the groups.     

Trauma history screening in a community mental health center

OBJECTIVE: This study assessed the lifetime prevalence of traumatic events among consumers of a community mental health center by using a brief trauma screening instrument. This study also examined the relationship between trauma exposure and physical and mental health sequelae and determined whether the routine administration of a trauma screening measure at intake would result in increased diagnoses of posttraumatic stress disorder (PTSD) and in changes in treatment planning in a practice setting. METHODS: A 13-item self-report trauma screening instrument, a shortened version of the Trauma Assessment of Adults instrument, was incorporated into the intake assessment process at a community mental health center (CMHC). A total of 505 out of 515 consumers who presented to the CMHC consecutively were surveyed from May 1, 2001, to January 31, 2002. Data from the initial assessment on trauma exposure and on rate of PTSD diagnosis were examined, and a chart review was conducted on 97 cases (19 percent) to determine the extent to which CMHC services addressed trauma-related problems. RESULTS: Data indicated that 460 consumers (91 percent) had been exposed to one or more traumatic life experiences. The number of traumatic events was negatively correlated with physical and mental health functioning on the 12-item Short-Form Health Survey (SF-12). Subjects with a history of sexual abuse scored significantly higher on the SF-12, reflecting poorer physical and mental health. Although the rate of PTSD diagnosis increased after implementation of the trauma screening instrument, the rates of actual PTSD treatment services provided did not change. CONCLUSIONS: This study strongly suggests that screening for trauma history should be a routine part of mental health assessment and may significantly improve the recognition rate of PTSD. However, much work remains to be done in implementing appropriate treatment.     

Trauma, symptoms of posttraumatic stress disorder, and associated problems among incarcerated veterans.

OBJECTIVE: To help improve treatment for incarcerated veterans, the study examined exposure to trauma, symptoms of posttraumatic stress disorder (PTSD), functional status, and treatment history in a group of incarcerated veterans. METHODS: A convenience sample of 129 jailed veterans who agreed to receive outreach contact completed the Life Event History Questionnaire, the PTSD Checklist-Civilian Version (PCL-C), and the Addiction Severity Index. Participants who had scores of 50 or above on the PCL-C, designated as screening positive for PTSD, were compared with those whose scores were below 50, designated as screening negative for PTSD. RESULTS: Some 112 veterans (87 percent) reported traumatic experiences. A total of 51 veterans (39 percent) screened positive for PTSD, and 78 veterans (60 percent) screened negative. Compared with veterans who screened negative for PTSD, those who screened positive reported a greater variety of traumas; more serious current legal problems; a higher lifetime use of alcohol, cocaine, and heroin; higher recent expenditures on drugs; more psychiatric symptoms; and worse general health despite more previous psychiatric and medical treatment as well as treatment for substance abuse. CONCLUSIONS: The findings encourage the development of an improved treatment model to keep jailed veterans with PTSD from repeated incarceration.     

Association of trauma exposure with psychiatric morbidity in military veterans who have served since September 11, 2001

Objective

This study examined the association of lifetime traumatic stress with psychiatric diagnostic status and symptom severity in veterans serving in the US military after 9/11/01.

Method

Data from 356 US military veterans were analyzed. Measures included a standardized clinical interview measure of psychiatric disorders, and paper-and-pencil assessments of trauma history, demographic variables, intellectual functioning, posttraumatic stress disorder (PTSD) symptoms, depression, alcohol misuse, and global distress.

Results

Ninety-four percent of respondents reported at least one traumatic stressor meeting DSM-IV criterion A for PTSD (i.e., life threatening event to which the person responded with fear, helplessness or horror), with a mean of four criterion A traumas. Seventy-one percent reported serving in a war-zone, with 50% reporting occurrence of an event meeting criterion A. The rate of current psychiatric disorder in this sample was: 30% PTSD, 20% major depressive disorder, 6% substance abuse or dependence and 10% for the presence of other Axis I psychiatric disorders. After accounting for demographic covariates and combat exposure, childhood physical assault and accident/disasters were most consistently associated with increased likelihood of PTSD. However, PTSD with no comorbid major depressive disorder or substance use disorder was predicted only by combat exposure and adult physical assault. Medical/unexpected-death trauma and adult physical assault were most consistently associated with more severe symptomatology.

Conclusions

Particular categories of trauma were differentially associated with the risk of psychiatric diagnosis and current symptom severity. These findings underscore the importance of conducting thorough assessment of multiple trauma exposures when evaluating recently post-deployed veterans.     

Trauma exposure and posttraumatic reactions in a community sample of Bedouin members of the Israel Defense Forces

Background: Limited available data indicate that minorities in military service face heightened risks for traumatic exposure and more severe posttraumatic reactions. This study explored traumatic exposure and impact on mental and physical health, functioning, and medical services utilization in a previously unstudied ethnic minority group of Bedouins enlisted in the Israeli Defense Forces. Methods: Participants were 317 community‐based Bedouin servicemen recruited through community outreach efforts. Axis I psychiatric diagnoses were determined by the Structured Clinical Interview for DSM‐IV Disorders; posttraumatic symptoms were measured with the Screen for Posttraumatic Stress Symptoms; and depression and anxiety symptoms were assessed by the Hopkins Symptom Checklist ?25 (HSCL‐25) Arabic version. Functional impairment and health service utilization were measured by a self‐report questionnaire. Results: Use of a stringent definition of trauma, restricted to experiences involving physical presence at the scene of the event, revealed that 75% of respondents reported potentially traumatizing events. Cap of these nearly 20% were diagnosed with posttraumatic stress disorder (PTSD), which was mostly co‐morbid with depression, alcohol abuse, or both. In spite of the widespread trauma exposure in this community, only those trauma‐exposed men who developed PTSD experienced extensive impact on their health, as indicated by associations with poor health status, physician‐diagnosed medical conditions, health‐related impairment in daily functioning, and frequent use of primary or specialty care services. Mental health services were typically not utilized. Conclusions: Detection of PTSD among Bedouin servicemen necessitates deliberate diagnostic efforts within primary care settings.

Comparisons Between Young,Middle-Aged,and Older Adult Sexual and Gender Minority Male Sexual Assault Survivors

ObjectiveThis study compared sexual abuse histories and depressive symptoms between younger, middle-aged, and older sexual and gender minority (SGM) male survivors.DesignParticipants completed a brief, online screener as part of a large comparative effectiveness psychotherapy trial.SettingSGM males 18 years or older, residing in the U.S. or Canada, were recruited online.ParticipantsThis study included younger (aged 18–39; n = 1,435), middle-aged (aged 40–59; n = 546), and older (aged 60+; n = 40) SGM men who reported a history of sexual abuse/assault.MeasurementsParticipants were asked about their sexual abuse history, experience of other traumas, symptoms of depression, and past 60-day mental health treatment engagement.ResultsOlder SGM men reported a lower rate of occurrence of adult sexual assault, exposure to other traumas, and depression. However, older and younger groups did not differ on any childhood sexual assault variable, the frequency of or number of attackers for adult sexual assault, the frequency of accidents and other injury traumas, or the occurrence or frequency of mental health treatment. Trauma load, including childhood and adult sexual assault, were more strongly related to current depressive symptoms than age group.ConclusionWhile there were some age-based or cohort differences in the rates of sexual trauma, the clinical response of both groups was similar. Implications for working clinically with middle-aged and older SGM men with untreated sexual assault-related mental health difficulties are discussed, including outreach and availability of gender- and older-inclusive survivor treatment and resources.     

Traumatic events and posttraumatic stress in childhood

CONTEXT: Traumatic events are common and are related to psychiatric impairment in childhood. Little is known about the risk for posttraumatic stress disorder (PTSD) across different types of trauma exposure in children. OBJECTIVE: To examine the developmental epidemiology of potential trauma and posttraumatic stress (PTS) in a longitudinal community sample of children. METHODS: A representative population sample of 1420 children aged 9, 11, and 13 years at intake were followed up annually through 16 years of age. Main Outcome Measure Traumatic events and PTS were assessed from child and parent reports annually to 16 years of age. Risk factors and DSM-IV disorders were also assessed. RESULTS: More than two thirds of children reported at least 1 traumatic event by 16 years of age, with 13.4% of those children developing some PTS symptoms. Few PTS symptoms or psychiatric disorders were observed for individuals experiencing their first event, and any effects were short-lived. Less than 0.5% of children met the criteria for full-blown DSM-IV PTSD. Violent or sexual trauma were associated with the highest rates of symptoms. The PTS symptoms were predicted by previous exposure to multiple traumas, anxiety disorders, and family adversity. Lifetime co-occurrence of other psychiatric disorders with traumatic events and PTS symptoms was high, with the highest rates for anxiety and depressive disorders. CONCLUSIONS: In the general population of children, potentially traumatic events are fairly common and do not often result in PTS symptoms, except after multiple traumas or a history of anxiety. The prognosis after the first lifetime trauma exposure was generally favorable. Apart from PTSD, traumatic events are related to many forms of psychopathology, with the strongest links being with anxiety and depressive disorders.     

Relationship of sexual assault history to somatic symptoms and health anxiety in women

Prior reports have pointed to a link between traumatic experiences and health consequences in women. The objective of this study was to determine whether there is an association between sexual assault history and measures of somatic symptoms and illness attitudes in a sample of female Veterans Affairs primary care patients, a group in whom high rates of sexual trauma have been reported. We conducted a cross-sectional study of a representative sample of 219 women in a Veteran's Affairs primary care outpatient clinic. Sexual assault history, somatic symptoms and health anxiety were assessed by self-report questionnaire. Multivariate analyses were used to examine relationships between sexual assault exposure and these outcomes. Ninety-seven women (43.9%) reported experience(s) of sexual assault (i.e., rape, attempted rape or being made to perform any type of sexual act through force or threat of harm). Sexual assault was associated with a significant increase in somatization scores, physical complaints across multiple symptom domains and health anxiety. Sexual assault was also a significant statistical predictor of having multiple sick days in the prior 6 months and of being a high utilizer of primary care visits in the prior 6 months. These data confirm a strong association between sexual trauma exposure and somatic symptoms, illness attitudes and healthcare utilization in women. Causal mechanisms cannot be inferred from these data. Studies in other cohorts are warranted.     

Traumatic life events and PTSD among women with substance use disorders and schizophrenia

OBJECTIVE: The authors assessed the prevalence of traumatic life events and posttraumatic stress disorder (PTSD) among women with schizophrenia or schizoaffective disorder and co-occurring substance abuse or dependence. The association between PTSD and specific traumatic life events was also examined. METHODS: Fifty-four drug-addicted women with schizophrenia or schizoaffective disorder participated in the study. All women were psychiatric outpatients and completed a large battery of structured clinical assessments. RESULTS: High rates of trauma, particularly physical abuse (81 percent), and revictimization--being abused both as a child and as an adult--were reported. The average number of traumatic life events reported was eight, and almost three-quarters of the sample reported revictimization. Rates of current PTSD were considerably higher than those documented in previous study samples of persons with serious mental illness and of drug-addicted women in the general community. PTSD was significantly associated with childhood sexual abuse and revictimization. CONCLUSIONS: The high levels of trauma and revictimization observed in the study highlight the need for the development of evidence-based interventions to treat trauma and its aftermath among women with schizophrenia or schizoaffective disorder. Given the overlap in symptoms between PTSD and schizophrenia, a better understanding is needed of how PTSD is expressed among people with schizophrenia. Recommendations and standards for the assessment of PTSD among this population need to be articulated. Finally, the comparatively high rates of PTSD suggest that the combination of schizophrenia or schizoaffective disorder and substance use disorder makes these women particularly vulnerable to adverse outcomes.     

The role of peritraumatic dissociation and gender in the association between trauma and mental health in a Palestinian community sample

OBJECTIVE: This research focused on gender-specific trauma exposure and mental health symptoms among Palestinians living in conditions of military violence. It also examined the gender-specific role of peritraumatic dissociation in moderating the association between lifetime trauma and mental health. METHOD: A random sample of 311 Palestinian women and 274 men ages 16-60 years from the Gaza Strip participated. The subjects were asked about lifetime trauma and peritraumatic dissociation during their most severe traumatic experience. Mental health was indicated by total scores and diagnostic variables of posttraumatic stress disorder (PTSD), anxiety, mood (depression), and somatization disorders. Symptoms of hostility were assessed as a total score. RESULTS: The women reported a lower level of lifetime trauma than the men, but exposure to trauma was associated with PTSD among both genders. Exposure to lifetime trauma was further associated with anxiety, mood, and somatoform disorders only among women but not among men. No gender differences were found in the level of peritraumatic dissociation. Analyses on moderating effects showed that peritraumatic dissociation made both men and women more vulnerable to symptoms of hostility and men to depressive symptoms when they were exposed to lifetime trauma. CONCLUSIONS: The results are consistent with previous studies in more peaceful conditions: men experience more traumatic events, whereas exposure is associated with more severe psychiatric disorders among women. Peritraumatic dissociation as an acute response to trauma constituted a risk for mental health symptoms in both genders.     

Are patients with severe depression traumatized by admission to an aged psychiatry ward?

BACKGROUND: Research on young psychiatric patients suggests that a significant proportion experience trauma and, in some cases, post-traumatic stress disorder (PTSD) as a result of hospitalization. This paper focuses on the evidence of trauma and PTSD associated with admission to an aged psychiatry ward. METHODS: Fifty former patients from three Melbourne hospitals were interviewed in their own homes, using a semi-structured, open-ended questionnaire. RESULTS: Thirty-four percent of participants reported having felt frightened, unsafe, powerless, and undermined at some time during their hospital stay. In 24% of cases these experiences could be described as "traumatic." None met criteria for PTSD. CONCLUSION: Most of the distressing experiences reported had been re-evaluated in the light of recovery or the passage of time. Nevertheless, finding ways to reduce the occurrence of such potentially traumatic experiences is clearly desirable. The evidence from this study suggests that providing opportunities for patients with depression to spend time apart from disturbed and disruptive patients would be helpful in this regard.     

Psychotic experiences in people who have been sexually assaulted

OBJECTIVE: In recent years, there has been a call for greater awareness of the relationship between trauma and psychosis, and several studies involving patients with psychotic disorders have found a link between traumatic life experience and the development of psychosis. However, little research has examined psychotic experiences in a traumatised population. METHOD: This study investigated psychotic experiences in a sample of 40 survivors of sexual assault (SA) compared to a control group without a history of sexual assault (measured using a self-report questionnaire) and examined the psychological factors that may contribute to the development of psychotic experiences in sexually traumatised individuals. In particular, the role of dissociation and cognitive factors such as post-traumatic cognitions were explored. RESULTS: Of the 26 sexually assaulted participants that were interviewed, 46% reported auditory hallucinations and 46% reported visual hallucinations. A significantly higher rate of psychotic phenomena (delusional ideation and predisposition to hallucinations) was found in the sexually assaulted group compared to the control group. Severity of SA trauma was significantly associated with severity of PTSD and psychotic symptomatology. Dissociation was strongly associated with all measures of psychotic phenomena and negative cognitions about the self and the world were associated with predisposition to hallucinations and delusional ideation. Regression analyses revealed that after controlling for the severity of SA trauma, dissociation and negative beliefs about the self significantly predicted delusional distress, and dissociation significantly predicted predisposition to visual hallucinations. CONCLUSIONS: These exploratory findings support the idea that psychotic phenomena may be caused by traumatic life experiences and highlight the need for further research. The implications of these results for research and clinical practice are discussed.
