Risk Factors for Course of Posttraumatic Stress Disorder Among Vietnam Veterans: A 14-Year Follow-Up of American Legionnaires.

Risk factors affecting the course of posttraumatic stress disorder (PTSD) are poorly understood. As part of a larger study on characterizing exposure to herbicides in Vietnam, the authors investigated this issue in a random sample of 1,377 American Legionnaires who had served in Southeast Asia during the Vietnam War and were followed over a 14-year period. High combat exposure, perceived negative community attitudes at homecoming, minority race, depression symptoms at Time 1, and more anger at Time 1 predicted a more chronic course. Community involvement at Time 1 was protective and associated with decreased risk at Time 2. Discomfort in disclosing Vietnam experiences was associated with an increased risk for developing PTSD but did not predict its course. Combat exposure predicted PTSD course more strongly than any other risk factor. Findings suggest recovery from PTSD is significantly influenced by perceived social support.

War Zone stress, personal and environmental resources, and PTSD symptoms in Gulf War Veterans: A longitudinal perspective.

Cross-sectional research has demonstrated a link between personal and environmental resources and development of emotional distress after war zone service. Less is known about the longitudinal relationship between resources and distress. The authors addressed this issue in a study of 348 Gulf War returnees tested at 2 time points. Resources decreased and posttraumatic stress disorder (PTSD) symptoms increased over time. Time 1 avoidance and family cohesion predicted PTSD symptoms at Time 2. Regression analyses revealed a bidirectional relationship over time between resources and PTSD symptoms. Time 1 resources predicted Time 2 psychopathology after accounting for Time 1 emotional distress. PTSD symptoms at Time 1 also predicted changes in coping and family relationships, even after accounting for Time 1 resources. Findings are consistent with the concept of a loss spiral (Hobfoll, 1989), in which resource factors and emotional sequelae to war stress exert reciprocal effects.

Posttraumatic stress disorder and retrospectively reported stressor exposure: A longitudinal prediction model.

There has been recent concern about the degree to which posttraumatic stress disorder (PTSD) symptomatology influences reports of prior exposure to highly stressful life events. In this longitudinal study of 2,942 male and female Gulf War veterans, the authors documented change in stressor reporting across 2 occasions and the association between change and PTSD symptom severity. A regression-based cross-lagged analysis was used to examine the relationship between PTSD symptom severity and later reported stressor exposure. Shifts in reporting over time were modestly associated with PTSD symptom severity. The cross-lagged analysis revealed a marginal association between Time 1 PTSD symptom severity and Time 2 reported stressor exposure for men and suggested that later reports of stressor exposure are primarily accounted for by earlier reports and less so by earlier PTSD symptomatology.

Posttraumatic stress disorder and depression symptomatology in a sample of Gulf War veterans: A prospective analysis.

The authors examined the relationship over time of posttraumatic stress disorder (PTSD) and depression symptoms in a sample of Gulf War veterans. A large sample (N?=?2,949) of Gulf War veterans was assessed immediately following their return from the Gulf region and 18–24 months later. Participants completed a number of self-report questionnaires including the Mississippi Scale for Combat–Related PTSD (T. M. Keane, J. M. Caddell, & K. L. Taylor, 1988) and the Brief Symptom Inventory (L. R. Derogatis & N. Melisaratos, 1983) at both time points and an extended and updated version of the Laufer Combat Scale (M. Gallops, R. S. Laufer, & T. Yager, 1981) at the initial assessment. A latent-variable, cross-lag panel model found evidence for a reciprocal relation between PTSD and Depression. Followup models examining reexperiencing, avoidance-numbing, and hyperarousal symptoms separately showed that for reexperiencing and avoidance-numbing symptoms, the overall reciprocal relation held. For hyperarousal symptoms, however, the association was from early hyperarousal to later depression symptoms only. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Depressive symptomatology in new mothers: A stress and coping perspective.

The aim of the present research was to test the utility of a stress-coping model of postpartum depression. Data were collected during the last trimester of pregnancy (n?=?197) and twice after the birth (4 weeks, n?=?180, and approximately 5 months, n?=?163). Coping resources and depressive symptomatology were assessed at Time 1, stress and coping were assessed at Time 2, and depressive symptomatology and partner ratings of coping effectiveness were assessed at Times 2 and 3. After control of the effects of initial depression, there was evidence of significant effects of levels of stress and coping responses on the Time 2 and Time 3 outcome measures. There was also some evidence linking coping resources (particularly self-esteem and family support) to postpartum depressive symptomatology.

Two-year posttreatment functioning and coping of substance abuse patients with posttraumatic stress disorder.

The 2-year posttreatment course of substance abuse patients with posttraumatic stress disorder (PTSD) was examined in a multisite evaluation of Veterans Affairs substance abuse treatment. Substance abuse patients with PTSD (SUD-PTSD) were compared with patients with only substance use disorder (SUD only) and patients with other comorbid psychiatric diagnoses (SUD-PSY) on outcomes during the 2 years after treatment. SUD-PTSD patients had a poorer long-term course on substance use, psychological symptom, and psychosocial outcomes than SUD-only and SUD-PSY patients. Coping methods were examined as mediators of the effect of PTSD on substance use outcomes. Greater use of avoidance coping styles and less use of approach coping at 1 year partially accounted for the association of PTSD with 2-year substance use. Treatments that address multiple domains of functioning and focus on alternative coping strategies are recommended for this population.

Coping strategies and posttraumatic stress disorder in female victims of sexual and nonsexual assault.

The coping behaviors and (posttraumatic stress disorder [PTSD]) symptoms of 215 female assault victims (103 rape victims and 112 nonsexual assault victims) were assessed within 2 weeks following the assault (Time I), and 133 of them (62%) were followed up 3 mo later (Time 2). Posttrauma symptom severity significantly decreased during the 3-mo study period, but PTSD severity levels at Times I and 2 were highly correlated. Three coping scales were constructed on the basis of exploratory factor analyses: Mobilizing Support, Positive Distancing, and Wishful Thinking. Three mo postassault, rape victims showed higher levels of wishful thinking and PTSD than nonsexual assault victims. Wishful thinking showed a positive association and positive distancing a negative association with PTSD severity, controlling for assault type, initial levels of PTSD severity, and other coping strategies. The clinical relevance of these findings is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Trauma reactivity, avoidant coping, and PTSD symptoms: A moderating relationship?

In the immediate aftermath of a traumatic event, many individuals experience physiological reactivity in response to reminders of the traumatic event that typically lessens over time. However, an overreliance on avoidant coping strategies may interfere with the natural recovery process, particularly for those who are highly reactive to trauma reminders. In the current investigation, we examined avoidant coping as a moderator of the association between heart rate reactivity to a trauma monologue measured shortly after a traumatic event and severity of posttraumatic stress disorder (PTSD) symptoms measured several months later. Fifty-five female survivors of assault completed PTSD diagnostic interviews and a self-report coping measure and participated in a trauma monologue procedure that included continuous heart rate measurement. These procedures were completed within 1 month of the assault and again 3 months postassault. After we controlled for the effect of initial symptom levels, the interaction of heart rate reactivity to the trauma monologue and avoidant coping measured at Time 1 was associated with PTSD symptom severity at Time 2. Individuals who are relatively highly reliant on avoidant coping strategies and relatively highly reactive to trauma reminders may be at greatest risk of maintaining or potentially increasing their PTSD symptoms within the first few months following the trauma. These findings may help inform early intervention efforts for survivors of traumatic events. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Caregiver burden in partners of Vietnam War veterans with posttraumatic stress disorder.

Caregiver burden in 58 partners of Vietnam War veterans with posttraumatic stress disorder (PTSD) was examined. The relationship between patient PTSD severity and caregiver burden, as well as the effect of several caregiver and patient variables on caregiver psychological status, was evaluated twice, an average of 8 months apart. Patient symptom severity was positively correlated with caregiver burden. Time 1 cross-sectional analysis indicated that greater caregiver burden was associated with greater caregiver psychological distress, dysphoria, and anxiety. Patient symptom severity also contributed to caregiver psychological distress; financial stress contributed to caregiver dysphoria and trait anxiety. Time 2 cross-sectional analyses essentially replicated the Time 1 findings. A third set of analyses examining change scores indicated that changes in caregiver burden for individuals in the sample positively predicted individual changes in caregiver psychological distress, dysphoria, and state anxiety.

Coping of school-age children in the sealed room during scud missile bombardment and postwar stress reactions.

Children's coping behaviors in the sealed room (a shelter against chemical and biological weapons) during scud missile attacks in the Persian Gulf War were examined in relation to postwar stress reactions. Three weeks after the war, 5th, 7th, and 10th graders (N?=?492) completed questionnaires assessing coping behaviors and emotional responses in the sealed room, as well as current stress reactions and posttraumatic stress disorder (PTSD). Despite an underlying feeling of tension, the dominant emotional stance in the sealed room was one of detached optimism. Common forms of coping involved information seeking, checking, and wishful thinking. Emotion-focused coping such as avoidance and distraction strategies was associated with less postwar stress reactions than persistence at direct problem-focused actions once the minimal actions available had been undertaken. Fifth graders were found to use less emotion-focused and more problem-focused coping strategies than were the 7th and 10th graders. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Direction of influence between posttraumatic and depressive symptoms during prolonged exposure therapy among children and adolescents.

Objective: Our objective in the present study was to examine the temporal sequencing of posttraumatic and depressive symptoms during prolonged exposure therapy for posttraumatic stress disorder (PTSD) among children and adolescents. Method: Participants were 73 children and adolescents (56.2% female) between the ages of 8 and 18. Participants completed self-report measures of posttraumatic stress and depression prior to every session. Measures included the Child PTSD Symptom Scale, Beck Depression Inventory, and Children's Depression Inventory. Results: Multilevel mediational analyses indicated reciprocal relations during treatment: Changes in posttraumatic symptoms led to changes in depressive symptoms and vice versa. Posttraumatic symptoms accounted for 64.1% of the changes in depression, whereas depressive symptoms accounted for 11.0% of the changes in posttraumatic stress. Conclusions: Prolonged exposure therapy may work primarily by reducing posttraumatic stress, which in turn reduces depression. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Chronic posttraumatic stress disorder and chronic pain in Vietnam combat veterans

A study was conducted to investigate chronic pain patterns in Vietnam veterans with posttraumatic stress disorder (PTSD). Combat veterans with PTSD completed standardized PTSD severity, pain, somatization, and depression measures. Of 129 consecutive out-patient combat veterans with PTSD, 80% reported chronic pain. In descending order were limb pain (83%), back pain (77%), torso pain (50%), and headache pain (32%). Compared to PTSD combat veterans without chronic pain, PTSD veterans who reported chronic pain reported significantly higher somatization as measured by the Minnesota Multiphasic Inventory 2 hypochondriasis and hysteria subscales. In the sample of 103 combat veterans with PTSD and chronic pain, MMPI 2 hypochondriasis scores and B PTSD symptoms (reexperiencing symptoms) were significantly related to pain disability, overall pain index, and current pain level MMPI 2 hypochondriasis and depression scores were also significantly related to percent body pain. These results are discussed in the context of current conceptualizations of PTSD.     

Does coping help? A reexamination of the relation between coping and mental health.

In a longitudinal community survey of 291 adults, we explored the relation between coping strategies and psychological symptoms. Respondents completed the revised Ways of Coping Scale (Folkman & Lazarus, 1985) for a self-named stressful episode. Factor analysis produced eight coping factors: three problem focused, four emotion focused, and one (support mobilization) that contained elements of both. Multiple regression analyses indicated bidirectionality in the relation between coping and psychological symptoms. Those in poorer mental health and under greater stress used less adaptive coping strategies, such as escapism, but coping efforts still affected mental health independent of prior symptom levels and degree of stress. We compared main versus interactive effects models of stress buffering. Main effects were confined primarily to the emotion-focused coping scales and showed little or negative impacts of coping on mental health; interactive effects, though small, were found with the problem-focused scales. The direction of the relation between problem-focused scales and symptoms may depend in part on perceived efficacy, or how the respondent thought he or she handled the problem. Implications for the measurement of adaptive coping mechanisms and their contextual appropriateness are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Post-traumatic stress disorder and coping after a natural disaster

This study examines the role of coping in the onset of post-traumatic stress disorder (PTSD) in a nonpatient population following exposure to a natural disaster. In contrast to other studies, the use of all coping strategies was found to be associated with the presence of PTSD rather than the absence of symptoms. These data suggest that coping (in this sense) represents a psychological process used to contain the distress caused by symptoms as well as to manage environmental adversity.     

Cholinergic/serotonergic interactions in hypothermia: implications for rat models of depression

Vietnam combat veterans (N = 151) with chronic posttraumatic stress disorder (PTSD) completed measures of atrocities exposure, combat exposure, PTSD symptom severity, guilt and interpersonal violence. PTSD symptom severity, guilt and interpersonal violence rates were similar to previously reported studies that examined treatment seeking combat veterans with PTSD. Controlling for combat exposure, endorsement of atrocities exposure was related to PTSD symptom severity, PTSD B (reexperiencing) symptoms, Global Guilt, Guilt Cognitions, and cognitive subscales of Hindsight-Bias/Responsibility and Wrongdoing. These results are discussed in the context of previous research conducted regarding atrocities exposure and PTSD.     

Coping, locus of control, social support, and combat-related posttraumatic stress disorder: A prospective study.

We examined the relations between coping, locus of control, and social support and combat-related posttraumatic stress disorder (PTSD). The sample consisted of 262 Israeli soldiers who suffered a combat stress reaction episode during the 1982 Lebanon war and were followed 2 and 3 years after their participation in combat. Cross-sectional analyses revealed significant relations between locus of control, coping, and social support and PTSD at the two points of assessment. Changes in PTSD from Time 1 to Time 2 were also associated with changes in coping. We discuss theoretical and methodological implications of the findings.

The relationship between coping styles, performance, and responses to stressful scenarios in police recruits.

This study investigated the relationship between coping styles and police recruits' stress responses and performance during a stressful event and the relationship between coping styles and traumatic symptoms. Recruits participated in a simulated stressful policing situation and were scored by expert raters. Distress measures included biological and psychological indicators of stress. Coping styles were associated with subjective and physiological distress but not with performance. Different coping styles were associated with different patterns of traumatic symptoms in the participants. Police recruits appear to rely on their training and skill sets in stressful situations regardless of how they manage their emotional response. Furthermore, the results suggest that different posttraumatic stress disorder manifestations may represent different pathologies, each associated with a different style of coping.

Determinants of coping: The role of stable and situational factors.

A longitudinal study of 243 students was conducted to examine the stable and situational influences on coping. At Time 1, measures of coping in response to a recent event (initial coping) and coping resources were obtained. At Time 2 (4 wks later), Ss described an event (coded for event type) they were currently experiencing. Situational appraisals were also assessed. At Time 3 (2 wks later), Ss' coping responses to the event were assessed. There was evidence that stable factors did influence coping behavior. Coping resources accounted for a significant proportion of variance in each of the measures of coping (except cautiousness), as did initial coping. There was evidence that the latter effects were dependent on cross-situational consistency in event type and levels of stress. After controlling for the stable influences, situational factors (situation type and situational appraisals) influenced the type of coping used.

A Longitudinal Study of Retirement in Older Male Veterans.

In this study, the authors examined the effect of retirement on psychological and physical symptoms in 404 older male veterans who were taking part in an ongoing longitudinal study. Hierarchical linear modeling was used to analyze symptom trajectories from preretirement, peri-retirement, and postretirement periods in veterans with either lifetime full or partial posttraumatic stress disorder (PTSD), trauma exposure only, or no traumatic exposure. As expected, the PTSD group experienced greater increases in psychological and physical symptoms during retirement, relative to the other groups. Retirement due to poor health in the PTSD group did not account for the findings regarding physical symptoms. Results indicate that clinicians should recognize and address the potential for older individuals with PTSD to experience difficulties during retirement.

Course and predictors of posttraumatic stress disorder among Gulf War veterans: A prospective analysis.

Rates and predictors of posttraumatic stress disorder (PTSD) over time are not well understood. This study is the first to look at the rates of PTSD immediately following war and 2 years later using a large cohort (N?=?2,949) of Gulf War veterans. Using a cut score to indicate presumptive PTSD, 3% of participants exceeded the cutoff at Time 1 compared with 8% at Time 2. Those who exceeded the cutpoint at Time 1 were up to 20 times more likely to exceed the cutpoint at Time 2 than those who did not exceed the cutpoint at Time 1. Women and those with high levels of combat exposure were at increased risk for PTSD at both times. Being young, being single, and having previous combat experience were associated with increased risk at Time 1 only, whereas reservists and enlisted personnel were at increased risk at Time 2 only. These findings indicate that, although low initially, rates of PTSD increased substantially over time. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
