Memory and attention in combat-related post-traumatic stress disorder (PTSD)

Vietnam combat veterans assigned diagnoses of PTSD were compared on measures of attention/concentration, new learning, and memory with Army National Guard enlistees who reported no unusual traumatic events or stress-related symptoms. Results showed that PTSD veterans performed more poorly than the comparison sample on a measure of verbal learning, exhibiting less proficient cumulative acquisition across repeated exposures, greater sensitivity to proactive interference, and more perseverative errors. Veterans with PTSD diagnoses also evidenced impairments in word fluency and visual attention/tracking abilities. These preliminary findings suggest that diagnoses of chronic PTSD in combat veterans are associated with cognitive performance deficits, when comparisons are made with military troops judged to be free of stress-related psychopathology. Results are consistent with self-reported complaints of concentration and memory impairments among PTSD-diagnosed clinical samples, thus highlighting the need for continued investigation of the neuropsychologlcal sequelae of prolonged stress exposure.

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.

War zone stress, personal resources, and PTSD in Persian Gulf War returnees.

Posttraumatic stress disorder (PTSD) can occur subsequent to war stress, but not all troops are negatively affected. A discriminant function model was used to study associations between personal and environmental resources and psychological outcomes subsequent to war zone stress. Among 775 Persian Gulf War exposed troops, 2 subsets were identified: 97 with PTSD diagnoses and 484 who had no psychological distress. A discriminant function, double cross-validated in random subsamples, classified 87% of troops, and demographic and stress severity variables did not alter results significantly. Personality hardiness commitment, avoidance coping, and perceived family cohesion emerged as consistent predictors of PTSD diagnosis. Findings suggest personal characteristics and environmental factors may alter vulnerability to negative war stress outcomes. Work is needed to identify mechanisms and causal pathways by which resource factors enhance or lower stress resistance.

PTSD and comorbid psychotic disorder: comparison with veterans diagnosed with PTSD or psychotic disorder.

Symptoms of posttraumatic stress disorder (PTSD), psychosis, general psychopathology, role functioning, violence potential, and cognitive and emotional aspects of psychotic states were compared in three groups of veterans. Groups were defined on the basis of their DSM-IV diagnoses: Psychotic disorder and war-related PTSD, war-related PTSD without psychotic symptoms, and psychotic disorder without PTSD. Veterans with PTSD and a comorbid psychotic disorder showed significantly higher levels of positive symptoms of psychosis, general psychopathology, paranoia, and violent thoughts, feelings, and behaviors than the other two groups. These data show that patients with comorbid PTSD and psychotic disorder show levels of cognitive, emotional, and behavioral disturbance that far exceed the levels of disturbance seen in patients with PTSD without psychosis or in patients with psychotic disorder.

Psychopathology in war-zone deployed and nondeployed Operation Desert Storm troops assigned graves registration duties

Early psychopathology outcomes were compared in troops mobilized for Persian Gulf graves registration duty but differentiated by war-zone deployment. Constructs of interest were Axis I psychiatric disorders, particularly posttraumatic stress disorder (PTSD), negative affect states, and somatic complaints. Psychometric instruments, including the Structured Clinical Interview for DSM-III-R, were administered to troops attending drill exercises. Although similar in personal characteristics and reporting low rates of premorbid psychopathology, groups differed in the prevalence of PTSD diagnoses, anxiety and anger symptoms, and somatic complaints. Current and lifetime PTSD rates of 48% and 65%, respectively, suggest that the psychological aftermath of war-zone participation involving the gruesome task of handling human remains was profound.

A Yoga Program for the Symptoms of Post-Traumatic Stress Disorder in Veterans

The purpose of this pilot study was to evaluate the feasibility and effectiveness of a yoga program as an adjunctive therapy for improving post-traumatic stress disorder (PTSD) symptoms in Veterans with military-related PTSD. Veterans (n = 12) participated in a 6 week yoga intervention held twice a week. There was significant improvement in PTSD hyperarousal symptoms and overall sleep quality as well as daytime dysfunction related to sleep. There were no significant improvements in the total PTSD, anger, or quality of life outcome scores. These results suggest that this yoga program may be an effective adjunctive therapy for improving hyperarousal symptoms of PTSD including sleep quality. This study demonstrates that the yoga program is acceptable, feasible, and that there is good adherence in a Veteran population.

Psychological symptoms and psychiatric diagnoses in operation desert storm troops serving graves registration duty

This clinical report describes symptoms of psychological and physical distress and psychiatric disorders in 24 Army Reservists who served war zone graves registration duty in support of Operation Desert Storm. Troops underwent comprehensive assessment for evidence of psychopathology that might be associated with war zone duty as one component of a debriefing protocol scheduled during regular drill exercises eight months after their return to the United States. Troops endorsed items suggestive of high war zone stress exposure, common symptoms of anxiety, anger, and depression, and multiple health and somatic concerns. Almost half of the sample met criteria for post-traumatic stress disorder, and diagnosis of this disorder was strongly associated with evidence of depressive and substance abuse disorders. The gruesome aspects of body recovery and identification in a war zone setting were cited as stressor elements of significant negative impact.

Differentiating overreporting and extreme distress: MMPI-2 use with compensation-seeking veterans with PTSD

This purpose of this study was to examine overreporting on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) in compensation-seeking veterans with posttraumatic stress disorder (PTSD). A sample of veterans tested during a V.A. hospital compensation and pension exam were given the MMPI-2 and measures of PTSD, depression, and combat exposure. Veterans MMPI-2s were only included in the analyses if their profile was extremely exaggerated, as measured by an F scale T score above 80, did not elevate the MMPI-2 VRIN and TRIN scales, and had a primary diagnosis of PTSD (n = 127). Using the Infrequency-Psychopathology, F(p), scale to distinguish overreporting from distress, it was found that 98 veterans elevated profiles due to distress, whereas 29 elevated due to overreporting, F(p) below and above 7, respectively. Differences between groups on MMPI-2 clinical scales and the other measures were assessed. Implications of these findings for assessing veteran response style and using the MMPI-2 with a PTSD population are discussed.

Early symptom predictors of chronic distress in Gulf War veterans

Although there is evidence that specific early hyperarousal, avoidance, and emotional numbing symptoms are associated with later posttraumatic stress disorder (PTSD) symptomatology among veterans, little is known about predictors of later non-PTSD-related psychological symptoms. One and 2 years after serving in the Gulf War, 348 military reservists were assessed for severity of war zone stress, PTSD, psychological distress, and stress-mediated physical complaints. Overall PTSD symptomatology and emotional numbing and hyperarousal symptom clusters increased over time, whereas re-experiencing and avoidance symptoms showed no change. Emotional numbing and hyperarousal symptoms at 1 year predicted generalized distress, depression, anxiety, hostility, and somatic symptoms at 2 years, whereas re-experiencing and avoidance symptoms did not. Findings highlight the importance of targeting early emotional numbing and hyperarousal symptom clusters to reduce longer-term psychological distress.

Exposure to War Trauma, War-Related PTSD, and Psychological Impact of Subsequent Hurricane

This study explored the impact of psychological outcomes to war on response to subsequent natural disaster. Participants were 312 military personnel, 66% of whom saw Gulf War duty. All were exposed to the 1992 Hurricane Andrew. Troops were compared on reported traumatic events, hurricane impact responses, and psychological symptoms in subgroups defined by war or no war exposure prior to hurricane and by presence or absence of war-related posttraumatic stress disorder (PTSD). Data were gathered in face-to-face clinical assessments. War trauma prior to hurricane was associated with more reported traumatic events, greater fears for safety during the hurricane, and heightened psychological symptoms. Troops with preexisting war-related PTSD showed more adverse psychological hurricane sequelae and reported more traumatic events, higher depression, anxiety, anger, PTSD symptoms, and physical symptoms, and lower self-esteem than those free of diagnoses. Results point to the negative influence of exposure to one traumatic event on the experience of and response to a subsequent stressor.
