The validation of a self-report measure of posttraumatic stress disorder: The Posttraumatic Diagnostic Scale.

The present article reports on the development and validation of a self-report measure of posttraumatic stress disorder (PTSD), the Posttraumatic Diagnostic Scale (PTDS), that yields both a PTSD diagnosis according to Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994; DSM-IV) criteria and a measure of PTSD symptom severity. Two-hundred forty-eight participants who had experienced a wide variety of traumas (e.g., accident, fire, natural disaster, assault, combat) were administered the PTSD module of the Structured Clinical Interview (SCID; Spitzer, Williams, Gibbons, & First, 1990), the PTDS, and scales measuring trauma-related psychopathology. The PTDS demonstrated high internal consistency and test-retest reliability, high diagnostic agreement with SCID, and good sensitivity and specificity. The satisfactory validity of the PTDS was further supported by its high correlations with other measures of trauma-related psychopathology. Therefore, the PTDS appears to be a useful tool for screening and assessing current PTSD in clinical and research settings.

A National Survey of Stress Reactions after the September 11, 2001, Terrorist Attacks

BACKGROUND People who are not present at a traumatic event may also experience stress reactions. We assessed the immediate mental health effects of the terrorist attacks on September 11, 2001. METHODS Using random-digit dialing three to five days after September 11, we interviewed a nationally representative sample of 569 U.S. adults about their reactions to the terrorist attacks and their perceptions of their childrens reactions. RESULTS Forty-four percent of the adults reported one or more substantial stress symptoms; 91 percent had one or more symptoms to at least some degree. Respondents throughout the country reported stress syndromes. They coped by talking with others (98 percent), turning to religion (90 percent), participating in group activities (60 percent), and making donations (36 percent). Eighty-five percent of parents reported that they or other adults in the household had talked to their children about the attacks for an hour or more; 34 percent restricted their childrens television viewing. Thirty-five percent of children had one or more stress symptoms, and 47 percent were worried about their own safety or the safety of loved ones. CONCLUSIONS After the September 11 terrorist attacks, Americans across the country, including children, had substantial symptoms of stress. Even clinicians who practice in regions that are far from the recent attacks should be prepared to assist people with trauma-related symptoms of stress.

Children on the Homefront: The Experience of Children From Military Families

OBJECTIVE: Although studies have begun to explore the impact of the current wars on child well-being, none have examined how children are doing across social, emotional, and academic domains. In this study, we describe the health and well-being of children from military families from the perspectives of the child and nondeployed parent. We also assessed the experience of deployment for children and how it varies according to deployment length and military service component. PARTICIPANTS AND METHODS. Data from a computer-assisted telephone interview with military children, aged 11 to 17 years, and nondeployed caregivers (n = 1507) were used to assess child well-being and difficulties with deployment. Multivariate regression analyses assessed the association between family characteristics, deployment histories, and child outcomes. RESULTS: After controlling for family and service-member characteristics, children in this study had more emotional difficulties compared with national samples. Older youth and girls of all ages reported significantly more school-, family-, and peer-related difficulties with parental deployment (P < .01). Length of parental deployment and poorer nondeployed caregiver mental health were significantly associated with a greater number of challenges for children both during deployment and deployed-parent reintegration (P < .01). Family characteristics (eg, living in rented housing) were also associated with difficulties with deployment. CONCLUSIONS: Families that experienced more total months of parental deployment may benefit from targeted support to deal with stressors that emerge over time. Also, families in which caregivers experience poorer mental health may benefit from programs that support the caregiver and child.

Dating Violence among Adolescents Prevalence, Gender Distribution, and Prevention Program Effectiveness

Relative to violence among adult intimate partners, violence among adolescent dating partners remains an understudied phenomenon. In this review, we assess the state of the research literature on teen dating violence. Our review reveals that the broad range of estimates produced by major national data sources and single studies make conclusions about the prevalence of teen dating violence premature. Similarly, our review of what is known about risk factors reveals inconsistency among studies. We assess published evaluations of adolescent dating violence prevention programs and discuss their findings and limitations. Finally, we discuss challenges to researchers in this area and suggest that additional investment in high-quality basic research is needed to inform the development of sound theory and effective prevention and intervention programs.

All symptoms are not created equal: the prominent role of hyperarousal in the natural course of posttraumatic psychological distress.

This 3-wave longitudinal study examined the natural course of posttraumatic stress disorder symptoms using data collected from young adult survivors of community violence. Three key findings emerged. 1. Mean levels of distress for each symptom cluster decreased over time, with reexperiencing decreasing most rapidly. 2. Cross-lagged panel analysis revealed that hyperarousal strongly influences, but is not generally influenced by, other symptoms clusters. 3. Trajectory analysis demonstrated that respondents for whom hyperarousal was the most pronounced baseline symptom showed lower overall symptom improvement relative to trauma exposed counterparts for whom hyperarousal was a less prominent early symptom. Implications for theory, research, and clinical practice are discussed.

Children’s Mental Health Care following Hurricane Katrina: A Field Trial of Trauma-Focused Psychotherapies

New Orleans school children participated in an assessment and field trial of two interventions 15 months after Hurricane Katrina. Children (N = 195) reported on hurricane exposure, lifetime trauma exposure, peer and parent support, posttraumatic stress disorder (PTSD), and depressive symptoms. Teachers reported on behavior. At baseline, 60.5% screened positive for PTSD symptoms and were offered a group intervention at school or individual treatment at a mental health clinic. Uptake of the mental health care was uneven across intervention groups, with 98% beginning the school intervention, compared to 37% beginning at the clinic. Both treatments led to significant symptom reduction of PTSD symptoms, but many still had elevated PTSD symptoms at posttreatment. Implications for future postdisaster mental health work are discussed.

Predicting response to exposure treatment in PTSD : The role of mental defeat and alienation

Not all patients with posttraumatic stress disorder benefit from exposure treatment. The present paper describes two cognitive dimensions that are related to inferior response to exposure in rape victims. First, individuals whose memories during reliving of the trauma reflected mental defeat or the absence of mental planning showed little improvement. Second, inferior outcome was correlated with an overall feeling of alienation or permanent change following the trauma. These results are based on blind ratings of transcripts of exposure treatment sessions from 10 women with good outcome and 10 women with inferior outcome. Patients in the two groups were matched for initial symptom severity and were comparable in many aspects of the assault. Patients who experienced mental defeat, alienation, or permanent change may require cognitive restructuring in addition to exposure.

Violence Exposure, Posttraumatic Stress Disorder, and Depressive Symptoms Among Recent Immigrant Schoolchildren

OBJECTIVE Many recent immigrant children are at risk for violence exposure and related psychological distress resulting from experiences before, during, and after immigration. This study examines the rates of violence exposure and associated symptoms among recent immigrant children in Los Angeles. METHOD 1,004 recent immigrant schoolchildren (aged 8-15 years) were surveyed about their prior exposure to violence and symptoms of posttraumatic stress disorder (PTSD) and depression. Participants included children whose native language was Spanish, Korean, Russian, or Western Armenian. RESULTS Participants reported high levels of violence exposure, both personal victimization and witnessing violence, in the previous year and in their lifetimes. Thirty-two percent of children reported PTSD symptoms in the clinical range, and 16% reported depressive symptoms in the clinical range. Although boys and older children were more likely to have experienced violence, girls reported more PTSD and depressive symptoms. Linear multiple regressions revealed that PTSD symptoms were predicted by both recent and lifetime violence exposure (p values < .001 and p < .05, respectively), when depressive symptoms and gender were controlled. On the other hand, depressive symptoms were predicted by recent victimization only (p < .001) when PTSD and gender were controlled. CONCLUSION These findings document the need for interventions addressing the psychological sequelae of violence exposure in immigrant children.

Obstacles in Implementing Exposure Therapy for PTSD: Case Discussions and Practical Solutions

Despite the proven efficacy of exposure techniques for the treatment of Post-Traumatic Stress Disorder, some obstacles can arise that interfere with successful implementation of exposure-based therapy. In this paper, the theory behind exposure therapy for PTSD is reviewed and basic implementation procedures are detailed. The ways in which three obstacles to treatment (extreme anger, emotional numbing, and overwhelming anxiety) can impede progress in therapy are discussed in terms of theory and case examples. Specific suggestions for circumventing these obstacles are offered, including modifying the exposure techniques and augmenting exposure by using stress inoculation techniques or cognitive therapy.

Impact of Teen Depression on Academic, Social, and Physical Functioning

OBJECTIVE: This study aimed to determine the impact of teen depression on peer, family, school, and physical functioning and the burden on parents. METHODS: Patients participated in a longitudinal study of teens with and without probable depression, drawn from 11 primary care offices in Los Angeles, California, and Washington, DC. A total of 4856 teens completed full screening assessments; 4713 were eligible for the study, and 187 (4.0%) met the criteria for probable depression and were invited to participate, as were teens who were not depressed. A total of 184 baseline assessments for teens with probable depression and 184 for nondepressed teens were completed, as were 339 (90%) parent interviews. Follow-up interviews were conducted with 328 teens (89%) and 302 parents (82%). Measures included teen reports of peer and parent support, 2 measures of school functioning, grades, physical health, and days of impairment. Parent reports included peer, school, and family functioning and subjective and objective burdens on parents. RESULTS: Teens with depression and their parents reported more impairment in all areas, compared with teens without depression at baseline, and reported more coexisting emotional and behavioral problems. Both depression and coexisting problems were related to impairment. There was a lasting impact of depressive symptoms on most measures of peer, family, and school functioning 6 months later, but controlling for coexisting baseline emotional and behavioral problems attenuated this relationship for some measures. CONCLUSION: Improvements in teen depression might have benefits that extend beyond clinical symptoms, improving peer, family, and school functioning over time.
