The interaction of posttraumatic stress disorder and depression among older combat veterans.

The question whether depression is related to trauma as part of posttraumatic stress disorder (PTSD) itself or whether it represents autonomous symptoms occurring separately (from PTSD) has not been answered. We addressed two issues: (a) What is the relationship between PTSD and depression as measured by continuous measures on outcomes? and (b) By removing depression components from the PTSD diagnosis, what is the impact on standard outcomes? Older veterans from World War II or Korea were interviewed and given self-report measures on PTSD and depression. The CAPS-1 and the MMPI-D were used as the continuous measures for PTSD and depression.

Assessment of older combat veterans with the clinician-administered PTSD scale.

A study of the posttraumatic stress disorder (PTSD) among older combat veterans of World War II and the Korean Conflict was conducted. The Clinician-Administered PTSD Scale (CAPS) was given to 125 older combat veterans, along with a computerized variant of the Structured Clinical Interview for DSM-III-R for PTSD, the SCID-DTREE. (The SCID-DTREE was itself validated against the full SCID).

Modes of long-term coping with trauma memories: relative use and associations with personality among Vietnam veterans with chronic PTSD.

Little is known about how individuals who develop chronic posttraumatic stress disorder (PTSD) cope with recurring trauma memories, or how enduring personality characteristics influence such coping. Focusing on 110 hospitalized Vietnam combat veterans with chronic PTSD, this exploratory study assessed the relative frequency of using eight ways of coping with war memories, and associations between relative use of these strategies and eight dysfunctional personality styles. As a secondary issue, associations between coping strategies, combat exposure, and PTSD severity were also examined.

Periodic limb movements of sleep in combat veterans with posttraumatic stress disorder.

Twenty-five veterans suffering from combat-related posttraumatic stress disorder were studied for 1-4 nights with all-night polysomnography. All subjects had sleep complaints. Analysis reveals that nineteen (76%) of the patients were found to have clinically significant periodic limb movements of sleep (PLMs) by the second night of study.

Posttraumatic stress disorder: conceptualization and treatment.

After a long history of both scientific and political debate, the notion that extreme psychological traumatic experiences, in and of themselves, could result in a severe, even malignant, psychiatric disorder is now established. In 1980 posttraumatic stress disorder finally became an officially classified anxiety disorder. Since then, the few controlled treatment outcome studies that have been carried out appear to indicate that the most effective treatment for PTSD is some form of exposure therapy.

Relationship of NEO-PI to personality styles and severity of trauma in chronic PTSD victims.

The relationship of the NEO-PI to personality disorders was evaluated in a clinical population. Eighty subjects with post-traumatic stress disorder (PTSD) were given this measure, along with the MCMI-II and PTSD and combat scales. Two questions were addressed: (1) What is the relationship of NEO-PI domains and facets to personality disorders?; and (2) What is this scale's relationship to PTSD problems? Results support previous studies that employed a clinical population, but with lower correlation coefficients.

A comparison of MMPI and MMPI-2 in PTSD assessment.

A sample of 47 Vietnam veterans with the diagnosis of combat-related Post-Traumatic Stress Disorder (PTSD) was administered the MMPI and MMPI-2. Pairwise comparisons were performed on the clinical scales, Harris Lingoes subscales, and scales relevant to the assessment of PTSD. Correlational analyses were performed as well.

MMPI profiles in PTSD as a function of comorbidity.

A sample of 135 Vietnam veteran inpatients with combat-related PTSD was sorted into three groups, depending upon the presence of concurrent psychiatric disorders: Depression (n = 68), Psychosis (n = 31), and Other (n = 36). Pairwise comparisons were made on the MMPI with respect to the validity indicators, clinical scales, four relevant Harris-Lingoes subscales, the Psychoticism content scale, and the MMPI-PTSD subscale. Results indicate variations in scale elevations as a function of comorbid diagnosis.

Cluster analysis of MCMI and MCMI-II on chronic PTSD victims.

A cluster analysis was used to identify groups of inpatients with confirmed post-traumatic stress disorder (PTSD) due to combat. In Study 1 the MCMI was administered to 256 subjects, in addition to the MMPI, PTSD measures, and background variables. Three clusters resulted: a Traumatic Personality (8-2), Schizoid Influence (8-2-1), and Antisocial Influence (8-6).

Dissociative experiences of Vietnam veterans with chronic posttraumatic stress disorder.

Interest in dissociation has been renewed, and its relationship to Post-traumatic Stress Disorder is especially intriguing. In this study 57 consecutively admitted chronic, combat-related Posttraumatic Stress Disorder sufferers were grouped by scores on a dissociative scale (Dissociative Experiences Scale). The three groups (high, medium, and low) were compared on personality measures (MMPI basic scales and subscales, and Millon's MCMI), Posttraumatic Stress Disorder measures, and a psychophysiological index of heart rate under baseline trauma conditions.

NEO-PI profiles in PTSD as a function of trauma level.

One hundred Vietnam veterans with combat-related PTSD were administered the NEO Personality Inventory (NEO-PI) and the Combat Exposure Scale and were sorted into three groups based on trauma exposure level. Results indicate no significant differences among the personality profiles of the three trauma-exposed groups. A normative NEO-PI profile for persons diagnosed with combat-related PTSD is presented, characterized by an extremely high Neuroticism score (T > 75) and an extremely low Agreeableness score (T < 25).

Relationship between the Millon Clinical Multiaxial Inventory and the Millon-II: value of scales for Aggressive and Self-defeating personalities in Posttraumatic Stress Disorder.

This study addressed two issues, the interrelationship between the Millon Clinical Multiaxial Inventory (MCMI) and the Millon II (MCMI-II) and the value of the new personality scales, Aggressive and Self-defeating, in a sample with diagnoses of combat-related Posttraumatic Stress Disorder. 100 confirmed cases of combat-related Posttraumatic Stress Disorder were given a battery of measures including both Millon inventories and the Minnesota Multiphasic Personality Inventory (basic scales and selected subscales). They were rated on discharge status during a structured treatment program.

Negative parenting behavior, combat exposure, and PTSD symptom severity. Test of a person-event interaction model.

The "personal characteristics" and "extreme event" hypotheses have been proposed as alternative explanations for the development of posttraumatic stress disorder (PTSD) among combat veterans. The person-event interaction model attempts to integrate both perspectives by hypothesizing that premilitary individual vulnerability characteristics play a greater role in influencing risk of PTSD or PTSD symptom severity at lower than at higher levels of exposure to traumatic combat stressors. Focusing on a sample of 57 Vietnam veterans undergoing inpatient treatment for diagnosed PTSD, we assessed this model by examining interactions between negative parenting behaviors in childhood (e.

A short form of the Mississippi Scale for Combat-Related PTSD.

At the present time, The Mississippi Scale for Combat-Related PTSD (Mississippi Scale) is the best paper-and-pencil measure of this disorder. This study carried out a test-retest reliability on 52 chronic Vietnam veterans with PTSD and established three psychometric criteria for item retention in order to establish a short form of the Mississippi Scale. Ten items met these criteria and had a test-retest reliability coefficient of .

Hidden PTSD in substance abuse inpatients among Vietnam veterans.

Alcohol use patterns among Vietnam combat veterans is an area with little research. This study evaluated three groups of Vietnam subjects on a chemical dependency unit who had a current Axis I diagnosis of alcohol abuse. No subject possessed a PTSD diagnosis.

Alexithymia among Vietnam veterans with posttraumatic stress disorder.

The authors studied 227 inpatients from a large Veterans Administration Medical Center to evaluate whether alexithymia is associated with posttraumatic stress disorder (PTSD) and to assess the validity of the Minnesota Multiphasic Personality Inventory (MMPI) alexithymia scale. Three groups--a carefully diagnosed PTSD group (N = 76), an alcohol abuse group (N = 76), and a general psychiatric group (N = 75)--were given a battery of psychological tests, including the MMPI, the Millon Clinical Multiaxial Inventory, and the Beck Depression Inventory, along with several cognitive measures. PTSD veterans were also evaluated on psychophysiologic indices (including a stressor) and on their subjective ratings to these indices.

Treatment outcomes of Vietnam veterans with PTSD and the consistency of the MCMI.

This study addresses two issues: treatment changes on the MCMI of Vietnam veterans with PTSD and test-retest reliability of the Millon Clinical Multiaxial Inventory (MCMI). Fifty Vietnam veterans carefully were identified for the diagnosis Post-Traumatic Stress Disorder (PTSD). They were admitted to a Special PTSD Treatment Unit that consisted of an intense 5-week period with focus on the revivified Vietnam experience.

MMPI F-K index among hospitalized Vietnam veterans.

The F-K index of the MMPI has been used as a marker of symptom overreporting. One population for which previous research has shown this pattern is Vietnam in-country veterans with PTSD. This study assessed the F-K index on 515 inpatients: 329 Vietnam in-country and 186 Vietnam-era patients.

Key determinants of the MMPI-PTSD subscale: treatment considerations.

Seventy-five "in country" Vietnam combat psychiatric inpatients were given a battery of measures upon admission to the medical center. These included the MMPI, VETS Adjustment Scale, State-Trait Anxiety Scale, Rotter Locus of Control, Profile of Mood Scale, and a variation of the Figley Stress Scale that measures current stress. Post-traumatic stress disorder (PTSD) was determined by the MMPI-PTSD subscale.

MMPI overreporting by Vietnam combat veterans.

The MMPI-PTSD scale is the only psychometric measure that has been cross-validated on Vietnam veterans for the determination of PTSD. Despite this, there may be problems with this scale related to symptom exaggeration. Three groups of Vietnam inpatients (N = 75) were defined carefully by both clinical and actuarial methods--PTSD combat, Non-PTSD combat, and Non-combat.
