Television exposure in children after a terrorist incident.

This study examined the influence of bomb-related television viewing in the context of physical and emotional exposure on posttraumatic stress symptoms--intrusion, avoidance, and arousal--in middle school students following the 1995 Oklahoma City bombing. Over 2,000 middle school students in Oklahoma City were surveyed 7 weeks after the incident. The primary outcome measures were the total posttraumatic stress symptom score and symptom cluster scores at the time of assessment. Bomb-related television viewing in the aftermath of the disaster was extensive. Both emotional and television exposure were associated with posttraumatic stress at 7 weeks. Among children with no physical or emotional exposure, the degree of television exposure was directly related to posttraumatic stress symptomatology. These findings suggest that television viewing in the aftermath of a disaster may make a small contribution to subsequent posttraumatic stress symptomatology in children or that increased television viewing may be a sign of current distress and that it should be monitored. Future research should examine further whether early symptoms predict increased television viewing and/or whether television viewing predicts subsequent symptoms.

Do post-traumatic stress disorder symptoms worsen during trauma focus group treatment?

Male inpatient veterans with chronic combat-related post-traumatic stress disorder (PTSD) participated in trauma focus group treatment and were assessed immediately before group participation and after group completion at time of discharge. Standard measures of core PTSD symptoms, depression, and anxiety were used. In addition, changes in PTSD symptoms were tracked on a weekly basis for the duration of group participation. Results indicated that a single direct elicitation of war-related traumatic memories in a group setting was not associated with symptom worsening. However, veterans also did not show improvement in symptoms severity. Possible reasons for this lack of impact are discussed along with implications for future treatment design and evaluation.

Posttraumatic stress disorder in a national sample of female and male Vietnam veterans: risk factors, war-zone stressors, and resilience-recovery variables.

Relationships among pretrauma risk factors (e.g., family instability, childhood antisocial behavior), war-zone stressors (e.g., combat, perceived threat), posttrauma resilience-recovery variables (e.g., hardiness, social support), and posttraumatic stress disorder (PTSD) symptom severity were examined. Data from a national sample of 432 female and 1,200 male veterans were analyzed using structural equation modeling. For both genders, direct links to PTSD from pretrauma, war-zone, and posttrauma variable categories were found; several direct associations between pretrauma and posttrauma variables were documented. Although war-zone stressors appeared preeminent for PTSD in men, posttrauma resilience-recovery variables were more salient for women. Researchers, policymakers, and clinicians are urged to take a broad view on trauma and its sequelae, especially regarding possible multiple exposures over time and the depletion and availability of important resources.

A test of behavioral family therapy to augment exposure for combat-related posttraumatic stress disorder.

This study tested a family-based skills-building intervention in veterans with chronic combat-related posttraumatic stress disorder (PTSD). Veterans and a family member were randomly assigned to 1 of 3 conditions: (a) waiting list, (b) 18 sessions of twice-weekly exposure therapy, or (c) 18 sessions of twice-weekly exposure therapy followed by 16 sessions of behavioral family therapy (BFT). Participation in exposure therapy reduced PTSD positive symptoms (e.g., reexperiencing and hyperarousal) but not PTSD negative symptoms. Positive symptom gains were maintained at 6-month follow-up. However, participation in BFT had no additional impact on PTSD symptoms.

Trauma and posttraumatic stress disorder in severe mental illness.

This research assessed the lifetime prevalence of traumatic events and current posttraumatic stress disorder (PTSD) in 275 patients with severe mental illness (e.g., schizophrenia and bipolar disorder) receiving public mental health services in Concord and Manchester, New Hampshire, and Baltimore, Maryland. Lifetime exposure to traumatic events was high, with 98% of the sample reporting exposure to at least 1 traumatic event. The rate of PTSD in our sample was 43%, but only 3 of 119 patients with PTSD (2%) had this diagnosis in their charts. PTSD was predicted most strongly by the number of different types of trauma, followed by childhood sexual abuse. The findings suggest that PTSD is a common comorbid disorder in severe mental illness that is frequently overlooked in mental health settings.

Posttraumatic stress disorder in adult female survivors of childhood sexual abuse: a comparison study.

This study compared symptoms of posttraumatic stress disorder (PTSD) in a group of 45 adult women in outpatient treatment for childhood sexual abuse (CSA) and a group of 31 women who reported no CSA. The comparison group consisted of women in outpatient treatment for problems in their committed relationships with male living partners. This research also investigated the traumatic impact of dual abuse (both childhood sexual and physical abuse). Standardized assessment instruments were used to measure PTSD, CSA, and childhood physical abuse (CPA). Results indicated that 86.7% of the CSA group met criteria for current PTSD in accordance with the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., revised; American Psychiatric Association, 1987), compared with 19.4% of the relationship distress group, providing support for CSA as an etiological agent for PTSD. In addition, 89% of the CSA survivors reported CPA. Multivariate analysis revealed that both CSA and CPA exposure variables accounted for a significant portion of the variance in PTSD symptoms in the CSA group.

Factors associated with entry into therapy in children evaluated for sexual abuse.

It is widely accepted that therapeutic intervention is an important and effective component in the treatment of the sexually abused child. The goal of this study was to identify children who are at risk for not receiving mental health services following sexual victimization. Nine-hundred and seventy-two children were followed for 6 months, and intervention by the Department of Children's Services (DCS), law enforcement agencies, and mental health professionals was monitored. Those children who were most likely to enter therapy were Caucasian, between the ages of 7 and 13, had cases in which DCS or law enforcement were involved, were placed outside the home, and experienced abuse of greater frequency. Implications of this study for intervention with child sexual abuse victims are discussed. Recommendations are made for future research.

Posttraumatic stress disorder in a clinical sample of adult survivors of childhood sexual abuse.

One hundred seventeen help-seeking adult survivors of childhood sexual abuse (CSA) were assessed to investigate the relationship between the level of self-reported CSA and posttraumatic stress disorder (PTSD). CSA was measured utilizing the Sexual Abuse Exposure Questionnaire, a new research instrument. Further preliminary psychometric properties of the instrument were reported. CSA was operationalized to include severity, duration, age of onset, number of perpetrators, and use of force. PTSD diagnostic status was assessed utilizing a standardized instrument, the Structured Clinical Interview for DSM-II-R. Eighty-six percent of survivors met full DSM-III-R criteria for a PTSD diagnosis at some point during their lives. Multivariate analysis indicated that CSA severity and duration accounted for significant portions of the variance in PTSD symptoms, providing support for their role as traumagenic variables.

Combat exposure and adult psychosocial adjustment among U.S. Army veterans serving in Vietnam, 1965-1971.

This study investigated the relationship between combat exposure and adult antisocial behavior in a sample of 2,490 male Army veterans of the Vietnam War who completed questionnaires about their psychological functioning. After adjustment for history of childhood behavior problems, posttraumatic stress disorder diagnosis, and demographic and military characteristics, it was found that veterans who experienced high and very high levels of combat were twice as likely to report adult antisocial behavior as veterans with no or low levels of combat and were also more likely to meet criteria for antisocial personality disorder. The results indicate that exposure to traumatic events during late adolescence or early adulthood is associated with multiple adult adjustment problems in vocational, interpersonal, and societal functioning. Treatment focusing on the effects of the trauma is likely to be necessary but not sufficient for improving affected veterans' behavior.

Prewar factors in combat-related posttraumatic stress disorder: structural equation modeling with a national sample of female and male Vietnam veterans.

Structural equation modeling was used to examine relationships among prewar factors, dimensions of war-zone stress, and current posttraumatic stress disorder (PTSD) symptomatology using data from 1,632 female and male participants in the National Vietnam Veterans Readjustment Study. For men, previous trauma history (accidents, assaults, and natural disasters) directly predicted PTSD and also interacted with war-zone stressor level to exacerbate PTSD symptoms for high combat-exposed veterans. Male veterans who entered the war at a younger age displayed more symptoms. Family instability, childhood antisocial behavior, and age had indirect effects on PTSD for men. For women, indirect prewar effects emanated from family instability. More attention should be given to critical developmental conditions, especially family instability and earlier trauma exposure, in conceptualizing PTSD in adults.

Psychological sequelae in adult females reporting childhood ritualistic abuse.

The present study sought to increase current scientific knowledge about the controversial issue of subjectively reported childhood ritualistic abuse by addressing several key unresolved issues. In particular, the possibility that those reporting ritualistic abuse may be characterized primarily by the severity of their abuse histories or the severity of their present psychological symptoms, rather than the veridicality of the ritualistic events, was explored. Adult female outpatients reporting childhood sexual abuse with ritualistic features were compared with a second group of women who reported childhood sexual abuse without ritualism. Measures included characteristics of childhood sexual and physical abuse, current posttraumatic stress disorder (PTSD) diagnostic status and symptom severity, and severity of current dissociative experiences. Women reporting ritualistic features scored significantly higher on measures of childhood sexual and physical abuse. Neither PTSD diagnostic status nor severity for PTSD nor dissociative experiences were significantly different between the groups. While preliminary in nature, these results suggest that it may be helpful to conceptualize reported childhood ritualistic abuse as indicative of the need to assess carefully for severe abuse and its predictable sequelae within existing traumatic victimization conceptual frameworks.

Effect of previous trauma on acute plasma cortisol level following rape.

OBJECTIVE: The authors examined the relationships among history of previous assault, severity of rape, acute plasma cortisol level after rape, and development of rape-related post-traumatic stress disorder (PTSD). METHOD: Blood samples were drawn from 37 adult female rape victims within 51 hours after they had been raped. The subjects were assessed for history of previous assault and for the presence of PTSD 17-157 days (mean = 90 days) after the rape. RESULTS: Women with a history of previous assault had a lower mean acute cortisol level after the rape but a higher probability of subsequently developing PTSD. A significant interaction between history of previous assault and the severity of the index rape was observed: only women who had never been assaulted before had higher cortisol levels following high-severity rapes (those which included injury or multiple types of penetration) than low-severity rapes. CONCLUSIONS: The authors conclude that previous traumatization may attenuate the acute cortisol response to trauma.

Childhood abuse experiences and combat-related PTSD.

Current literature on the etiology of combat-related PTSD strongly implicates combat trauma exposure as a primary etiological factor. However, studies of premilitary variables have produced conflicting results, perhaps in part due to methodological inconsistencies and failure to employ standardized measures. The present study examines one premilitary variable, childhood physical abuse history. Using a standardized measure developed by child abuse researchers, forty-five percent of veterans with PTSD were identified as recipients of abusive physical punishment during childhood. A positive correlation between physical abuse history and severity of combat-related PTSD was found. These preliminary findings set the stage for further investigation of the child abuse variable and underscore the need for treatment of veterans with combat-related PTSD which addresses developmental traumagenic events.

Posttraumatic stress disorder in a clinical sample of adults sexually abused as children.

Forty-seven help-seeking, adult survivors of childhood sexual abuse (CSA) were assessed to examine the relationship between the level of CSA exposure and the subsequent development of posttraumatic stress disorder. CSA exposure was operationalized to include the overall level of exposure, frequency and duration of the abuse, age of onset, use of force, perceived life threat, and the occurrence of penetration. Participants were administered standardized measures of PTSD, including the Structured Clinical Interview of DSM-III-R (SCID). On the SCID, 69% of the survivors met full DSM-III-R criteria for PTSD. Significant correlations were found between several overall exposure measures and PTSD diagnostic status and the intensity of PTSD symptomatology. Similar relationships were identified with the duration and frequency of the abuse, the age of onset, and the use of force. This study is important in that it utilized standardized measures of PTSD and found a significant incidence of PTSD among adult CSA survivors.

Posttraumatic stress disorder among battered women: risk and resiliency factors.

This study proposed that diagnosable levels of PTSD would be found among battered women and that the level of exposure to violence in the battering relationship would be an important contributing factor to the development of PTSD while other pre-trauma and post-trauma variables such as social support, intercurrent life events, religiosity, and developmental family stressors would also be related to PTSD symptom levels. Fifty-three battered women were given standardized self-report measures to assess these variables. As hypothesized, a significant proportion of battered women in the sample were diagnosed as PTSD positive. Multiple regression analyses revealed that violence exposure severity, recency of the last abusive episode, social support, intercurrent life events, intrinsic religiosity, and developmental family stressors predicted 43% of the variance in PTSD symptomatology.

Statistical analysis for single-case designs. Evaluating outcome of imaginal exposure treatment of chronic PTSD.

A recently developed statistical method for single-case subject designs based on classical test theory was used to examine the efficacy of imaginal exposure treatment for posttraumatic stress disorder (PTSD) in four Vietnam veterans. The method was sensitive to intraindividual changes across different outcome measures even when relatively few data points were available. Two veterans clearly improved from exposure and maintained their gains at 3- and 15-month follow-ups. One veteran improved marginally, whereas one veteran's symptoms worsened. Changes in heart rate monitored over the first two imaginal exposures indicated that veterans with greater heart-rate habituation responded better to exposure than did veterans with less or no habituation. The results suggest that the statistical method illustrated here has some advantages over other methods (e.g., visual inspection, time-series analysis) for examining clinical interventions in single-case designs.

Antisocial behavior and post-traumatic stress disorder in Vietnam veterans.

Assessment data from 118 Vietnam-era veterans seeking psychological services at two Los Angeles Veterans Administration Medical Centers were analyzed to examine the potential relationships between number of preadult and adult antisocial behaviors, as defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-III; American Psychiatric Association, 1980) criteria for antisocial personality disorder, level of combat exposure, and development of combat-related post-traumatic stress disorder (PTSD). Results of hierarchical regression analyses indicated that combat exposure level was related significantly to PTSD symptomatology, whereas number of preadult antisocial behaviors was not. However, both combat exposure level and preadult behaviors, which were not correlated significantly, were related significantly to number of adult antisocial behaviors. There were no significant interaction effects. Results were consistent with a theoretical model of PTSD development that emphasizes the role of trauma vs. premorbid characterological factors. In addition, the significant association between combat exposure and adult antisocial behavior indicates that trauma may play a role in the development and/or maintenance of adult antisocial behaviors observed in some Vietnam veterans.
