Physical and mental health costs of traumatic war experiences among Civil War veterans.

BACKGROUND: Hundreds of thousands of soldiers face exposure to combat during wars across the globe. The health effects of traumatic war experiences have not been adequately assessed across the lifetime of these veterans. OBJECTIVE: To identify the role of traumatic war experiences in predicting postwar nervous and physical disease and mortality using archival data from military and medical records of veterans from the Civil War. DESIGN: An archival examination of military and medical records of Civil War veterans was conducted. Degree of trauma experienced (prisoner-of-war experience, percentage of company killed, being wounded, and early age at enlistment), signs of lifetime physician-diagnosed disease, and age at death were recorded. SETTING AND PARTICIPANTS: The US Pension Board surgeons conducted standardized medical examinations of Civil War veterans over their postwar lifetimes. Military records of 17,700 Civil War veterans were matched to postwar medical records. MAIN OUTCOME MEASURES: Signs of physician-diagnosed disease, including cardiac, gastrointestinal, and nervous disease; number of unique ailments within each disease; and mortality. RESULTS: Military trauma was related to signs of disease and mortality. A greater percentage of company killed was associated with signs of postwar cardiac and gastrointestinal disease (incidence risk ratio [IRR], 1.34; P < .02), comorbid nervous and physical disease (IRR, 1.51; P < .005), and more unique ailments within each disease (IRR, 1.14; P < .005). Younger soldiers (<18 years), compared with older enlistees (>30 years), showed a higher mortality risk (hazard ratio, 1.52), signs of comorbid nervous and physical disease (IRR, 1.93), and more unique ailments within each disease (IRR, 1.32) (P < .005 for all), controlling for time lived and other covariates. CONCLUSIONS: Greater exposure to death of military comrades and younger exposure to war trauma were associated with increased signs of physician-diagnosed cardiac, gastrointestinal, and nervous disease and more unique disease ailments across the life of Civil War veterans. Physiological mechanisms by which trauma might result in disease are discussed.

Web-based methods in terrorism and disaster research.

This article provides an overview of the use of the Internet for conducting studies after terrorist attacks and other large-scale disasters. We begin with a brief summary of the scientific and logistical challenges of conducting such research, followed by a description of some of the most important design features that are required to produce valid findings. We then describe one approach to Internet surveys that, although not perfect, addresses many of the challenges well. We close with some thoughts about how the Internet-based methods available today are likely to develop further in coming years.

The role of perceived similarity in supportive responses to victims of negative life events.

The authors examined whether participants' perceived similarity to an ostensible victim of a negative life event influenced their supportiveness during a live interaction. Two competing models were considered: (a) increased similarity would be associated with increased supportiveness through attraction to the target and (b) increased similarity would be associated with decreased supportiveness through anxiety (due to heightened vulnerability). Participants (N = 241) met individually with a confederate posing as a cancer patient. Reactions were assessed, including verbal and nonverbal behaviors, both before and after the interaction, by participants themselves and by observers of the interaction. Results supported a model based on the classic similarity/attraction paradigm: Perceived similarity indirectly predicted participant-reported supportiveness/warmth and smiling through its relationship to attraction. Results extend the literature on similarity and attraction to the stress and coping arena and suggest that emphasizing perceived similarities to victims would be beneficial.

Nationwide longitudinal study of psychological responses to September 11.

CONTEXT: The September 11, 2001, attacks against the United States provide a unique opportunity to examine longitudinally the process of adjustment to a traumatic event on a national scale. OBJECTIVE: To examine the degree to which demographic factors, mental and physical health history, lifetime exposure to stressful events, September 11-related experiences, and coping strategies used shortly after the attacks predict psychological outcomes over time. DESIGN, SETTING, AND PARTICIPANTS: A national probability sample of 3496 adults received a Web-based survey; 2729 individuals (78% participation rate) completed it between 9 and 23 days (75% within 9 to 14 days) after the terrorist attacks. A random sample of 1069 panelists residing outside New York, NY, were drawn from the wave 1 sample (n = 2729) and received a second survey; 933 (87% participation rate) completed it approximately 2 months following the attacks. A third survey (n = 787) was completed approximately 6 months after the attacks. MAIN OUTCOME MEASURES: September 11-related symptoms of acute stress, posttraumatic stress, and global distress. RESULTS: Seventeen percent of the US population outside of New York City reported symptoms of September 11-related posttraumatic stress 2 months after the attacks; 5.8% did so at 6 months. High levels of posttraumatic stress symptoms were associated with female sex (odds ratio [OR], 1.64; 95% confidence interval [CI], 1.17-2.31), marital separation (OR, 2.55; 95% CI, 1.06-6.14), pre-September 11 physician-diagnosed depression or anxiety disorder (OR, 1.84; 95% CI, 1.33-2.56) or physical illness (OR, 0.93; 95% CI, 0.88-0.99), severity of exposure to the attacks (OR, 1.31; 95% CI, 1.11-1.55), and early disengagement from coping efforts (eg, giving up: OR, 1.68; 95% CI, 1.27-2.20; denial: OR, 1.33; 95% CI, 1.07-1.64; and self-distraction: OR, 1.31; 95% CI, 1.07-1.59). In addition to demographic and pre-September 11 health variables, global distress was associated with severity of loss due to the attacks (beta =.07; P =.008) and early coping strategies (eg, increased with denial: beta =.08; P =.005; and giving up: beta =.05; P =.04; and decreased with active coping: beta = -.08; P =.002). CONCLUSIONS: The psychological effects of a major national trauma are not limited to those who experience it directly, and the degree of response is not predicted simply by objective measures of exposure to or loss from the trauma. Instead, use of specific coping strategies shortly after an event is associated with symptoms over time. In particular, disengaging from coping efforts can signal the likelihood of psychological difficulties up to 6 months after a trauma.
