Multiple diagnosis in posttraumatic stress disorder. The role of war stressors

[Alcohol and drug consumption in students exposed to the Dawson College shooting: a gender-based analysis]

OBJECTIVE

To study alcohol and drug addiction incidence in students exposed to the Dawson College shooting within the 18 months following the event, to identify the precursors of a psychoactive substance addiction development while considering the severity of event exposure, and to examine whether alcohol use, 18 months after the event, is related to any of the various posttraumatic stress disorder (PTSD) symptom groups.

METHOD

The population of this study was comprised of all the Dawson College students at the time of the event. Analyses were conducted with 854 students enrolled in the college at the time of the shooting.

RESULTS

Five per cent of women and 7% of men showed, for the first time in their life, a problem with substance addiction following the shooting. In men, young age, lifetime suicidal ideation, and having seen the killer during the shooting are the main precursors of incident accident cases. None of the studied precursors were significant in women. Men and women were also different in terms of PTSD symptoms predicting alcohol use 18 months after the shooting.

CONCLUSION

The study highlights the importance of considering a person's sex when studying their psychoactive substance use following a trauma.

Effect of depression on recovery from PTSD

It has been suggested that the treatment strategy needs to be reviewed and changed if depression occurs in patients with posttraumatic stress disorder (PTSD). We analyzed data extracted from the Marmara Epidemiological Survey (MES) which had examined 683 survivors at 3 years after a devastating earthquake. Fifty three cases (40.5%) out of the 131 cases with PTSD had also been diagnosed with MDD. Comorbid PTSD and MDD group has significantly lower rates of recovery from PTSD in comparison to PTSD without MDD (26.4% vs. 47.4% respectively). Rates of past psychiatric disorder and past traumatic experience were significantly more frequent among the comorbid group. Moreover, comorbidity of PTSD and MDD was clearly associated with greater psychological distress, more severe PTSD, and diminished perceived social support. Past psychiatric disorder, General Health Questionnaire (GHQ-12) and Multidimensional Scale of Perceived Social Scale (MSPSS) total scores succeeded in predicting the comorbidity of PTSD and MDD significantly.

Trauma and victims: epidemiology of post-traumatic stress disorder

Scopo- Presentare una esaustivareviewdegli studi riguardanti l'epidemiologia del DPTS condotti nella popolazione generale, tra i soggetti a rischio, e, infine, tra gruppi clinicamente selezionati.Disegno- AttraversoExcepta Medica PsychiatryCD-ROM 1980-1993 (ottobre), utilizzando come parola chiave «Post-Traumatic Stress Disorder», sono stati identificati 1.057 articoli pubblicati nel periodo considerate Sono stati anche consultati altridata basedella letteratura medica (MEDLINE CD-ROM 1988-1993); è stata quindi operata una ricerca manuale su tutti i numeri delJournal of Traumatic Stress. Risultati- In totale, 135 lavori che hanno soddisfatto i criteri di inclusione prescelti sono stati inclusi nella review. I due terzi (n = 86, 64%) di queste ricerche sono state condotte negli USA. Solo 8 (6%) sono le indagini effettivamente realizzate nei paesi del Terzo Mondo. L'ampiezza del campione varia da un minimo di 11 soggetti, numero riscontrato in due studi, sino ad un massimo di 22.436, per un campione medio di 500 e mediano di 108. Per quanto attiene ai metodi di valutazione, in un terzo degli studi (n = 45, 33%), i ricercatori hanno impiegato un questionario (auto- o etero- somministrato). In un altro terzo delle ricerche elencate (n = 44, 33%) e stata somministrata un'intervista strutturata (la DIS, la SCID, o la SADS), mentre nei rimanenti studi la valutazione diagnostica si è basata o su una procedura clinica non strutturata, o sulla somministrazione di altri strumenti specifici dai quali è possibile inferire una diagnosi di DPTS (M-PTSD, IES, SCL-90-R,o pochi altri). In 77 studi (57%) i ricercatori hanno basato la loro valutazione sui criteri diagnostici propri del DSM-III, mentre in altri 55 (41%) su quelli del DSM-III-R. La prevalenza del DPTS e analizzata quindi separatamente per le diverse popolazioni studiate.Conclusioni- Nell'arco di soli 13 anni, a partire cioe dalla definizione di criteri diagnostici operazionali ben definiti per il DPTS, sono stati condotti numerosi studi volti ad indagare la prevalenza, i fattori di rischio, la storia naturale, il decorso e l' esito di questo disturbo tra campioni diversi di popolazioni a rischio; inoltre, anche il livello qualitativo di queste ricerche, per quanto attiene alia sofisticazione metodologica, si è accresciuto sensibilmente in un tempo tutto sommato breve. Molte aree, pero', restano tuttora inesplorate, ed inoltre appare imperativo avviare ricerche estensive tra le popolazioni dei paesi in via di sviluppo, maggiormente esposte a disastri naturali o provocati dall'uomo.

Deployment stressors of the Iraq War: insights from the mainstream media

A comprehensive understanding of the stressors of the Iraq War is needed to ensure appropriate postdeployment assessments and to inform empirical inquiries. Yet we are unaware of any published studies that address the range of stressors experienced by this cohort. Thus, in the present study, we report the results of an interpretive literature review of mainstream media reports published from the beginning of the Iraq War in March 2003 to March 2005. This literature revealed a combination of stressors associated with traditional combat, insurgency warfare, and peacekeeping operations. The increasing deployment of National Guard/Reservist personnel, older soldiers, and women highlights additional stressors associated with sexual harassment and assault, preparedness and training, and life and family disruptions. This is a cause for concern as war-zone stressors have been implicated in postdeployment health outcomes, including intimate partner violence and child maltreatment, immediate physical and mental health, and long-term adjustment.

Diagnostic co-morbidity in 2300 psychiatric out-patients presenting for treatment evaluated with a semi-structured diagnostic interview

BACKGROUND

The largest clinical epidemiological surveys of psychiatric disorders have been based on unstructured clinical evaluations. However, several recent studies have questioned the accuracy and thoroughness of clinical diagnostic interviews; consequently, clinical epidemiological studies, like community-based studies, should be based on standardized evaluations. The Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project is the largest clinical epidemiological study using semi-structured interviews assessing a wide range of psychiatric disorders conducted in a general clinical out-patient practice. In the present report we examined the frequency of DSM-IV Axis I diagnostic co-morbidity in psychiatric out-patients.

METHOD

A total of 2300 out-patients were interviewed with the Structured Clinical Interview for DSM-IV (SCID) upon presentation for treatment.

RESULTS

The mean number of current and lifetime DSM-IV Axis I disorders in the 2300 patients was 1.9 (s.d.=1.5) and 3.0 (s.d.=1.8) respectively. The majority of patients were diagnosed with two or more current disorders, and more than one-third were diagnosed with three or more current disorders. Examination of the most frequent current disorders in the patients with the 12 most common principal diagnoses indicated that the pattern of co-morbidity differed among the disorders. The highest mean number of current co-morbid disorders was found for patients with a principal diagnosis of post-traumatic stress disorder and bipolar disorder.

CONCLUSIONS

Clinicians should assume that psychiatric patients presenting for treatment have more than one current diagnosis. The pattern of co-morbidity varies according to the principal diagnosis.

Relative impact of adverse events and screened symptoms of posttraumatic stress disorder and depression among active duty soldiers seeking mental health care

Symptoms of depression and posttraumatic stress are among the most studied psychological difficulties among soldiers. Such symptoms have been linked to a history of adverse events among both civilians and combat veterans. There is a paucity of research on this topic that can be applied to an active duty clinical population. Intake screening data were reviewed for 1,626 soldiers presenting to an outpatient mental health clinic to identify variables, including history of potentially traumatic experiences, associated with screened symptoms of posttraumatic stress disorder (PTSD) and depression. Demographics such as age, gender, and military rank, as well as number of adverse childhood experiences were significant predictors of screened PTSD and depression. A history of deployment to a combat zone predicted screened PTSD, but not depression. The role of childhood abuse as a risk factor is discussed and highlighted in the etiology of symptoms for soldiers seeking mental health care.

The Psychosocial Effects of Combat: The Frequently Unseen Injury

The psychosocial issues related to deployment and combat duty are complex. Deployment may result in psychiatric casualties that are either the result of inadequate coping with the stressors of deployment or acute stress reactions caused by the trauma of battle, that is, combat stress reactions. Combat duty is associated with traumatic events, deprivation, and exposure to war atrocities that may result in acute, delayed or chronic psychosocial issues during and afer returning from deployment. Although protective and mediating factors ar in place, 11% to 17% of combat veterans are at risk for mental disorders in 3 to 4 months after return from combat duty. Combat veterans include service members directly involved in combat as well as those providing support to combatants, that is, nurses. All combat veterans are at risk for experiencing the negative effects of deployment. Frequent deployments of active duty, reserve, and National Guard members have become commonplace. This translates into a disruption of live for anyone associated with the military, as well as an increased focus on the psychosocial impact of combat across the nation. Modern warfare has resulted in multiple changes in policy that govern military operations. Initiatives that focus on the stabilization of service members and their families may impact mental health outcomes of service members returning from combat duty. An initiative toward decreasing the stigma of receiving mental health care is warranted. Mental health issues must be addressed before and during deployment to ensure optimum individual and unit functioning. Early identification and treatment of mental health problems may decrease the psychosocial impact of combat and thus prevent progression to more chronic and severe psychopathology such as depression and PTSD.

Deployment stressors, gender, and mental health outcomes among Gulf War I veterans

Findings indicate that war-zone exposure has negative implications for the postdeployment adjustment of veterans; however, most studies have relied on limited conceptualizations of war-zone exposure and focused on male samples. In this study, an array of deployment stressors that were content valid for both female and male Gulf War I military personnel was examined to elucidate gender differences in war-zone exposure and identify gender-based differential associations between stressors and mental health outcomes. While women and men were exposed to both mission-related and interpersonal stressors and both stressor categories were associated with mental health outcomes, women reported more interpersonal stressors and these stressors generally had a stronger impact on women's than on men's mental health. Exceptions are described, and implications are discussed.

Predictors of police suicide ideation

Further inquiry into processes that lead to suicide in the police occupation is necessary. Suicide ideation in police officers and possible correlates associated with such ideation is explored in this paper. The focus was on psychologically traumatic police work experiences, the development of posttraumatic stress (PTSD) in officers, and the inordinate use of alcohol associated with this condition. The impact of these occupationally based factors and their association with suicide ideation has not yet been fully explored. Results suggest that certain traumatic police work exposures increase the risk of high level PTSD symptoms, which subsequently increase the risk of high alcohol use and suicide ideation. The combined impact of PTSD and increased alcohol use led to a ten-fold increase risk for suicide ideation.

[Mental disorders in victims of terrorism and their families]

BACKGROUND AND OBJECTIVE

To find out whether victims of terrorism and their relatives have higher prevalence of affective, anxiety, and alcohol abuse disorders than the general population.

MATERIAL AND METHOD

Between January 1997 and January 2001, 544 families affected by terrorist violence in Spain were interviewed. Victims and their relatives (n = 1,021) were evaluated by means of the PRIME-MD. They were classified according to the degree of involvement in the attacks as: relatives of victims (RV), direct victims (DV) and direct victims who were also relatives of other victims (DVRV). Their scores were compared with those of a primary health-care sample.

RESULTS

Depressive symptoms were more prevalent among victims (DVRV, 59.2%; DV, 57.6%; RV, 50.2%) than among controls (40.0%) (p = 0.036) and their prevalence was directly related to the degree of involvement in the attacks. Similar results were obtained for anxiety disorders (DVRV, 52.6%; DV, 56.5%; RV, 45.0%, and controls 26.4%) (p = 0.017). Alcohol abuse prevalence (DVRV, 6.6%; RV, 5.9%) was very close to that of the primary health-care sample (4.8%) with the exception of direct victims (DV, 15.9%) in whom it was higher (p = 0.016).

CONCLUSIONS

The prevalence of psychopathology was higher among victims of terrorism than among primary health-care patients and it was directly related to the involvement in the attack. Low perceived social support, family and personal history of psychiatric disease, and type of attack (explosives) increased the risk of suffering mental disorders.

Chronicity in posttraumatic stress disorder and predictors of the course of posttraumatic stress disorder among primary care patients

The present study examined the course of posttraumatic stress disorder (PTSD) in a sample of 84 primary care patients. More specifically, this study investigated the role of Axis I comorbidity, psychosocial impairment, and treatment participation in the maintenance of an episode of chronic PTSD and whether patients at follow-up met criteria for PTSD (full remission) or continued to exhibit residual PTSD symptoms and impairment (partial PTSD). Diagnostic structured interviews established all clinical diagnoses and information on the course of anxiety disorder symptoms, psychosocial functioning, and treatment status. Using a prospective, longitudinal design, this study found that during the first 2 years of follow-up, the probability of no longer meeting full DSM-IV criteria for PTSD was .69, and .18 for full remission from PTSD. The number of comorbid anxiety disorders and degree of psychosocial impairment at intake were significantly related to remission status (i.e., full and partial PTSD). This study suggests that, in a primary care setting, PTSD is a persistent illness, and that many subjects who have recovered from PTSD continue to suffer from subthreshold symptoms of PTSD.

Epidemiologic studies of trauma, posttraumatic stress disorder, and other psychiatric disorders

This paper reviews recent epidemiologic studies of posttraumatic stress disorder (PTSD) in the general population. Estimates of the prevalence of exposure to traumatic events vary with the method used to ascertain trauma exposure and the definition of the stressor criterion. Changes in the DSM-IV definition of "stressor" have increased the number of traumatic events experienced in the community that can be used to diagnose PTSD and thus, the number of PTSD cases. Risk factors for PTSD in adults vary across studies. The 3 factors identified as having relatively uniform effects are 1) preexisting psychiatric disorders, 2) a family history of disorders, and 3) childhood trauma. In civilian populations, women are at a higher risk for PTSD than are men, following exposure to traumatic events. Most community residents have experienced 1 or more PTSD-level traumas in their lifetime, but only a few succumb to PTSD. Trauma victims who do not succumb to PTSD are not at an elevated risk for the subsequent onset of major depression or substance use disorders, compared with unexposed persons.

Psychological impact of fire disaster on children and their parents

Six weeks following a major wildfire, children's psychosocial functioning was examined. Employing a multimethod assessment approach, the short-term mental health consequences of the fire were evaluated. Individual adjustment was compared between families who reported high levels of loss as a result of the fire (high-loss group) and families who reported relatively low levels of loss resulting from the fire (low-loss group). Standardized assessment procedures were employed for children and adolescents as well as their parents. In general, high-loss participants reported slightly higher levels of post-traumatic stress disorder (PTSD) symptoms and significantly higher scores on the Impact of Events Scale. PTSD symptoms reported by parents were generally significantly correlated with (but not concordant with) PTSD symptoms reported by their children. The high-loss group scored significantly higher on the Resource Loss Index than did the low-loss group. Preexisting and comorbid disorders and previous stressors are described. A methodological framework for future studies in this area is discussed.

Comorbid anxiety disorders in civilians seeking treatment for posttraumatic stress disorder

Research indicates that posttraumatic stress disorder (PTSD) is associated with high rates of comorbid psychiatric diagnoses. Yet, it remains unknown whether PTSD is associated with greater comorbidity relative to patients with other anxiety disorders. This study examined prevalence of comorbid anxiety disorders with PTSD relative to other disorders among a treatment-seeking population. Patients with PTSD (n = 83) evidenced greater overall comorbidity as compared to patients with other anxiety (n = 151) or Axis I (n = 73) disorders. Compared to patients with panic disorder, patients with PTSD were more likely to be diagnosed with depression and social phobia, but not other anxiety disorders. Extent of anxiety disorder comorbidity was not related to PTSD severity. These findings are discussed in terms of their relevance for treatment of PTSD.

Somatic symptoms in Gulf War mortuary workers

OBJECTIVE

The objective of this article is to examine the relationship between exposures to the dead and the development of somatic symptoms.

METHODS

We studied the pre-post responses of 352 military men and women who worked in the mortuary that received the dead from the Persian Gulf War (Operation Desert Storm) in 1990 to 1991. Symptoms of somatization were measured before and after exposure to the dead. The respondents were volunteers and nonvolunteers for assignment to the mortuary; some had prior experience in handling the dead and some did not. Four groups of participants were examined based on the degree of exposure to remains. Age, sex, volunteer status, prior experience handling remains, and preexposure measures of depression and mutilation fear were statistically controlled.

RESULTS

Postexposure somatic symptoms increased significantly over preexposure levels for the two groups with the most exposure to the dead.

CONCLUSIONS

These results provide additional evidence that exposure to the dead is related to somatic distress.

A unique panic-disorder presentation among Khmer refugees: the sore-neck syndrome

This article describes a previously unreported cultural syndrome among Khmer refugees. This common presentation of distress centers on the complaint of a sore neck, the sufferer fearing that wind-and-blood pressure may burst the vessels in this area. During an acute episode, a Khmer endures many--if not all--of the following neck-and-head complaints: headache, blurry vision, a buzzing in the ear, and dizziness. While in the throes of the sore-neck attack, the patient frequently experiences palpitations as well as other symptoms of autonomic arousal, such as diaphoresis, shortness of breath, and trembling. A sufferer of sore-neck episodes often meets panic disorder criteria. In a clinic survey, thirty-five out of eighty-five patients (41%) were found to currently suffer the "sore-neck syndrome" (i.e., to have endured at least one episode in the last month), with almost all of these thirty-five patients (80%) fearing death during the acute event. The sore-neck syndrome represents a common and important way in which distress becomes embodied. The clinician must learn this body language; otherwise, the patient's communication of psychic, interpersonal, and physical pain goes unheard--and grave somatic suffering and disability unattended to--discounted as puzzling somatic complaints and unreasonable obsessionalism about blood pressure.

Panic disorder among Vietnamese refugees attending a psychiatric clinic: prevalence and subtypes

This study surveys Vietnamese refugees attending two psychiatric clinics to determine both the prevalence of panic disorder (PD) as well as panic attack subtypes in those suffering PD. A culturally valid adaptation of the SCID-panic module (the Vietnamese Panic Disorder Survey or VPDS) was administered to 100 Vietnamese refugees attending two psychiatric clinics. Utilizing culturally sensitive panic probes, the VPDS provides information regarding both the presence of PD and panic attack subtypes during the month prior to interview. Of 100 patients surveyed, 50 (50%) currently suffered PD. Among the 50 patients suffering PD, the most common panic attack subtypes during the previous month were the following: "orthostatic dizziness" (74% of the 50 panic disorder patients [PDPs]), headache (50% of PDPs), wind-induced/temperature-shift-induced (24% of PDPs), effort-induced (18% of PDPs), gastro-intestinal (16% of PDPs), micturition-induced (8% of PDPs), out-of-the-blue palpitations (24% of PDPs), and out-of-the-blue shortness of breath (16% of PDPs). Five mechanisms are adduced to account for this high PD prevalence as well as the specific profile of subtypes: 1) a trauma-caused panic attack diathesis; 2) trauma-event cues; 3) ethnic differences in physiology; 4) catastrophic cognitions generated by cultural syndromes; and 5) a modification of Clark's spiral of panic.

Effects of exposure to death in a war mortuary on posttraumatic stress disorder symptoms of intrusion and avoidance

Exposure to the dead has been an important subject for traumatic stress research, considering that such exposure is a risk factor for posttraumatic stress disorder (PTSD). Individuals required to handle the dead from war are exposed to multiple stressors. No previous studies, however, have examined pre- and post-responses to traumatic death. We studied the pre-post responses of 352 military men and women who worked in the mortuary that received the dead from the Persian Gulf War (Operation Desert Storm) in 1990 to 1991. The respondents were volunteers and nonvolunteers for assignment to the mortuary; some had prior experience in handling the dead and some did not. Symptoms of intrusion and avoidance were measured before and after exposure. Four groups were examined based on the degree of exposure to remains. Age, sex, volunteer status, and prior experience handling remains were statistically controlled. Post-exposure intrusion symptoms increased significantly for all groups exposed to the dead. Increased post-exposure avoidance symptoms were present in the two groups with the greatest exposure to remains. There were no significant increases in intrusion or avoidance in the unexposed group.

Panic disorder among Cambodian refugees attending a psychiatric clinic. Prevalence and subtypes

This study surveys Khmer refugees attending two psychiatric clinics to determine both the prevalence of panic disorder as well as panic attack subtypes in those suffering panic disorder. A culturally valid adaptation of the SCID-panic module, the Cambodian Panic Disorder Survey (CPDS), was administered to 89 consecutive Cambodian refugees attending these psychiatric clinics. Utilizing culturally sensitive panic probes, the CPDS provides information regarding both the presence of panic disorder and panic-attack subtypes during the month prior to interview. Of 89 patients surveyed at two psychiatric clinics, 53 (60%) currently suffered panic disorder. Among the 53 patients suffering panic disorder, the most common panic attack subtypes during the previous month were the following: "sore neck" [51% of the 53 panic disorder patients (PDPs)], orthostatic dizziness (49% of PDPs), gastrointestinal distress (26% of PDPs), effort induced (21% of PDPs), olfactory induced (21% of PDPs), and "while-sitting dizziness" (16% of PDPs).

Prevalence of personality disorders among combat veterans with posttraumatic stress disorder

Many combat veterans with PTSD have co-occurring symptoms of other forms of psychopathology; however, there have been limited studies examining personality disorders among this population. The few extant studies typically have assessed only two or three personality disorders or examined a small sample, resulting in an incomplete picture and scope of comorbidity. This study assessed all DSM-III-R personality disorders in 107 veterans in a specialized, inpatient unit. Using the Structured Clinical Interview for DSM-III-R Personality Disorders, 79.4% of the participants were diagnosed with at least one personality disorder: 29.9% received only one diagnosis, 21.5% had two, 15.9% had three, and 12.1% had four or more. The most frequent single diagnoses were Avoidant (47.2%), Paranoid (46.2%), Obsessive-Compulsive (28.3%), and Antisocial (15.1%) personality disorders.

Fifty years later: the long-term psychological adjustment of ageing World War II survivors

OBJECTIVE

Most studies of the long-term after-effects of war have focused on survivors seeking treatment or financial compensation. The present study examined the current psychological adjustment of a community sample of ageing World War II (WW II) survivors, including survivors of bombardments, persecution, resistance, combat and other violence.

METHOD

A community sample of 4057 Dutch WW II survivors answered a 4-page postal questionnaire. Of these, 1461 survivors answered a second follow-up questionnaire.

RESULTS

Even 50 years after World War II, a statistically significant but modest relationship was found to exist between exposure to shocking war events and current psychological adjustment in terms of symptoms of post-traumatic stress disorder (PTSD), anxiety and anger. A total of 66 respondents (4.6%) met the criteria for PTSD. The highest level of current PTSD (13%) was found among survivors of persecution. The lowest level of PTSD (4%) was found among civilian war victims and resistance participants, while military veterans had an intermediate score (7%). With regard to absolute numbers, civilian war victims represented the largest proportion of PTSD sufferers.

CONCLUSION

In a study of a community sample of WW II survivors, we found that most of these survivors had no severe symptoms of PTSD. Nevertheless, probably tens of thousands of Dutch individuals are still suffering from long-term after-effects from World War II. For these vulnerable survivors, the ageing process will complicate the coping process.

Axis I diagnostic comorbidity and borderline personality disorder

Borderline personality disorder (PD) has been the most studied PD. Research has examined the relationship between borderline PD and most axis I diagnostic classes such as eating disorders, mood disorders, and substance use disorders. However, there is little information regarding the relationship of borderline PD and overall comorbidity with all classes of axis I disorders assessed simultaneously. In the present study, 409 patients were evaluated with semistructured diagnostic interviews for axis I and axis II disorders. Patients with a diagnosis of borderline PD versus those who did not receive the diagnosis were assigned significantly more current axis I diagnoses (3.4 v 2.0). Borderline PD patients were twice as likely to receive a diagnosis of three or more current axis I disorders (69.5% v 31.1%) and nearly four times as likely to have a diagnosis of four or more disorders 147.5% v 13.7%). In comparison to nonborderline PD patients, borderline PD patients more frequently received a diagnosis of current major depressive disorder (MDD), bipolar I and II disorder, panic disorder with agoraphobia, social and specific phobia, posttraumatic stress disorder (PTSD), obsessive-compulsive disorder (OCD), eating disorder NOS, and any somatoform disorder. Similar results were observed for lifetime diagnoses. Overall, borderline PD patients were more likely to have multiple axis I disorders than nonborderline PD patients, and the differences between the two groups were present across mood, anxiety, substance use, eating, and somatoform disorder categories. These findings highlight the importance of performing thorough evaluations of axis I pathology in patients with borderline PD in order not to overlook syndromes that are potentially treatment-responsive.

Psychiatric diagnosis in clinical practice: is comorbidity being missed?

The recognition of comorbidity has important clinical significance. Comorbidity predicts a poorer outcome for patients with depressive and anxiety disorders, and the presence of multiple psychiatric disorders is associated with greater psychosocial impairment. In routine clinical settings, an unstructured interview is typically used to assess patients. However, unstructured interviews may result in missed diagnoses, with potential negative clinical consequences. The goal of the present study was to examine whether diagnostic comorbidity is less frequently identified during a routine clinical evaluation versus a semistructured diagnostic interview. Axis I diagnoses derived from structured and unstructured clinical interviews were compared in two groups of psychiatric outpatients in the same practice setting. Five hundred individuals presenting for an intake appointment to a general adult psychiatric practice underwent a routine unstructured clinical interview. Subsequent to completion of the first study, the method of conducting diagnostic evaluations was changed and 500 individuals were interviewed with the Structural Clinical Interview for DSM-IV Axis I Disorders (SCID). The two groups had similar demographic characteristics and scored similarly on symptom questionnaires. Individuals interviewed with the SCID were assigned significantly more axis I diagnoses than individuals assessed with an unstructured interview. More than one third of the patients interviewed with the SCID were diagnosed with three or more disorders, in contrast to fewer than 10% of the patients assessed with an unstructured interview. Fifteen disorders were more frequently diagnosed in the SCID sample, and these differences occurred across mood, anxiety, eating, somatoform, and impulse-control disorder categories. The results suggest that in routine clinical practice, clinicians underrecognize diagnostic comorbidity. Anxiety, somatoform, and not otherwise specified (NOS) disorders were the most frequently underdetected disorders. The implications of underdiagnosis for the treatment outcome are discussed.

Chronicity in posttraumatic stress disorder (PTSD) and predictors of course of comorbid PTSD in patients with anxiety disorders

The purpose of this study was to examine the course of comorbid posttraumatic stress disorder (PTSD) in 54 patients with another anxiety disorder. Using a prospective longitudinal design, the present study found that during the first 5 years of follow-up the probability of full remission from a chronic episode of PTSD was .18. Findings from this and other research confirm clinical impressions that a substantial number of people never fully remit from their PTSD even after many years. Variables associated with a longer time to remit from an episode of chronic PTSD were a history of alcohol abuse and a history of childhood trauma.

Psychological impact and prevalence of traumatic events in a student sample in Israel: the effect of multiple traumatic events and physical injury

The prevalence of exposure and the psychological impact of traumatic events were studied in 983 Israeli university students. The psychological effects of exposure to single versus multiple traumatic events, and the effects of trauma-related physical injury were also examined. It was found that 67% of the respondents reported having been exposed to at least one traumatic event. Of those exposed, 6% were diagnosed as having posttraumatic stress disorder (PTSD). Men were more at risk for exposure, but women were more at risk for PTSD. Women and the physically injured showed more psychological distress following exposure. Being exposed to one type of traumatic event was associated with increased psychological distress, but being exposed to multiple types of traumatic events was associated with lowering of distress. The results are discussed in comparison with similar studies from the United States.

Criminal victimization, posttraumatic stress disorder, and comorbid psychopathology among a community sample of women

This paper provides information on the relation between victimization status, crime factors, posttraumatic stress disorder (PTSD), and several other psychological disorders among a community sample of women. Results indicated that victims of crime were more likely than nonvictims to suffer from PTSD, major depressive episode, agoraphobia, obsessive-compulsive disorder, social phobia, and simple phobia. Furthermore, life threat was associated with increased risk of major depression, agoraphobia, obsessive-compulsive disorder, and social phobia. Completed rape was strongly related to almost every disorder assessed, while robbery and burglary were not related to any disorder. When demographics, victimization status, and crime factors were entered hierarchically into multivariate logistic regressions with PTSD in the final step, associations between victimization status, other crime characteristics (e.g., life threat, injury), and non-PTSD Axis I disorders were greatly reduced. This suggests that PTSD may be an important mediating factor in the victimization-psychopathology relation for many disorders.

Use of the hand test in the assessment of combat-related stress

This study investigated the effectiveness of the Hand Test in discriminating the differential symptomatology of posttraumatic stress (PTS) in Vietnam combat veterans (VCVs). Participants were 108 VCV outpatients, 85 of whom met the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994) criteria for posttraumatic stress disorder (PTSD), and 23 patients that were found to meet some, but not the minimum criteria, required for a diagnosis of PTSD by the DSM-IV. The latter group of patients was classified into a subclinical PTSD, posttraumatic stress symptoms (PTSS) group. Results showed higher levels of overall psychopathology, a vulnerable capacity for coping, and a tendency for feelings of inadequacy and inferiority in the PTSD group. The PTSD group also exhibited more limited interaction with the world around them than the PTSS group, which may be indicative of withdrawal, apathy, or a lack of concern with environmental activities and goals. These findings are discussed in relation to the assessment, understanding, and treatment of PTS symptomatology and PTSD.

Posttraumatic stress disorder and comorbidity in Australian Vietnam veterans: risk factors, chronicity and combat

OBJECTIVE

The objective of this study was to examine the relationship between combat-related posttraumatic stress disorder (PTSD) and comorbid DSM-III-R psychiatric diagnoses to determine commonalities in risk factors, relative onsets and the role of combat exposure.

METHOD

An epidemiological cohort study using standardised psychiatric, social and health interviews was undertaken with a national random sample of male Australian Army Vietnam veterans. Interviews and searches of military records yielded risk factors for PTSD, which were examined for association with each psychiatric diagnosis. Relative onsets of PTSD and each Diagnostic Interview Schedule diagnosis were compared. Comorbidity odds ratios were adjusted for combat exposure effects using logistic regression, and the relation between each diagnosis and combat was assessed after controlling for PTSD.

RESULTS

Commonality of risk factor profile was evident for several diagnoses, and for many their onset preceded PTSD onset. Combat was independently related to only a few diagnoses after controlling for PTSD, and PTSD remained strongly associated with several conditions after controlling for combat exposure.

CONCLUSIONS

The analysis suggests that the disorders that may constitute risk factors or vulnerabilities for PTSD comprise depression and dysthymia, antisocial personality disorder, agoraphobia and simple phobia, while those that may be consequent on PTSD are panic and generalised anxiety disorder, drug use disorders and somatoform pain disorder. Alcohol and drug use disorders and social phobia may have a mixed aetiology, while obsessive-compulsive disorder may be serendipitously related to PTSD through an association with risk of combat. Gambling disorder is unrelated.

Should there be a clinical typology of posttraumatic stress disorder?

OBJECTIVE

The current classification of posttraumatic stress disorder in acute, chronic and delayed-onset types is incomplete and of limited usefulness. The present paper explores the possibilities of a clinically-based typology that would reflect both the patients' syndromic presentation and modern research findings.

METHOD

Review of current clinical and research literature, with a critical examination of proposed typologies, parameters utilised, applicability and relevance; elaboration of theoretical and practical bases of a clinical typology of posttraumatic stress disorder.

RESULTS

None of the existing posttraumatic stress disorder typologies presents a clinically comprehensive scope. A typology supported by literature findings and clinical observations is proposed. The six clinical types are depressive, dissociative, somatomorphic, psychotomorphic, organomorphic and 'neurotic-like'. Substance abuse and personality disorder-like variants remain as areas of investigation.

CONCLUSIONS

The proposed typology, while accepting the nuclear manifestations of posttraumatic stress disorder, highlights prominent coexisting symptoms that define the clinical appearance of different patients. The typological approach in posttraumatic stress disorder does not carry the ambiguities of comorbidity, and facilitates a more specific and appropriate management of the cases.

PTSD symptoms and comorbid mental disorders in Israeli war veterans

BACKGROUND

The purpose of this study was to investigate patterns of mental disorders co-morbid with PTSD symptoms in young Israeli men exposed to combat.

METHOD

Six hundred and seventeen subjects were selected via a general population sample and evaluated in a two-phase case-identification procedure, culminating in a modified SADS-L interview, administered by psychiatrists.

RESULTS

Major depressive disorder (OR = 3.2), substance use disorders (OR = 1.9) and personality disorders (OR = 3.0) occurred more frequently in men reporting symptoms of PTSD than in men who had been under fire who did not report symptoms. With the possible exception of personality disorders, comorbid disorders did not constitute risk factors for PTSD. Comorbid PTSD and RDC disorders were associated with increased help-seeking.

CONCLUSIONS

The results suggest similar rates and types of PTSD comorbidity in Israeli war veterans as in veterans in the US assessed in general population studies, and are consistent with shared risk factors for PTSD and comorbid disorders.

Unique patterns of comorbidity in posttraumatic stress disorder from different sources of trauma

While there are many studies of comorbidity in combat veterans with posttraumatic stress disorder (PTSD), studies of PTSD from other sources of trauma (e.g., disasters, crimes, and civil violence) are just beginning to emerge. This is the first formal review comparing patterns of comorbidity in PTSD from different sources of trauma. Specific attention is given to the relative frequencies of substance abuse, depression, generalized anxiety, phobic, panic, somatization, psychotic, and personality disorders. The findings reveal that although similarities exist, the comorbidity profiles differ according to the type of trauma experienced and the population studied. Additionally, the evidence suggests that the associated psychiatric disorders are not truly comorbid, but are interwoven with the PTSD.

Rorschach measures of posttraumatic stress in Persian Gulf War veterans: a three-year follow-up study

The long-term psychological effects of war-related stress were assessed with the Rorschach 3 years after the Persian Gulf War. Rorschach data are presented for 30 U.S. Marine reservists at a 3-year follow-up who reported experiencing symptoms of posttraumatic stress (PTS) initially after Operation Desert Storm (ODS), and for 25 Marine reservist controls who did not participate in ODS. Results showed significant differences over time between the initial evaluation data and follow-up, and between initial evaluation and the control group on selected Rorschach variables associated with coping ability and PTS. Scores associated with acute distress, capacity for coping and control, and feeling overwhelmed all were found to significantly decrease over time. These findings are discussed in relation to the assessment and understanding of PTS symptomatology over time.

Characteristics of posttraumatic stress disorder-alcohol abuse comorbidity in women

Trauma characteristics and symptoms were examined in 12 women diagnosed with posttraumatic stress disorder (PTSD) and alcohol abuse (AA), 13 women with PTSD only, and 22 controls. Participants served during the Vietnam era. Women completed diagnostic interviews and a questionnaire battery. Results showed that PTSD-AA women reported more childhood sexual abuse and sexual victimization during wartime service than the other two groups. Groups did not differ on other childhood trauma variables, nor on adult physical assault and traditional wartime stressor exposure. PTSD-AA women reported more PTSD, dissociation, and borderline personality traits than the other two groups. These results suggest that trauma type, specifically sexual victimization across the life span, is an important factor in dual diagnosis in women, and that women with PTSD-AA have a particularly severe level of symptoms relative to women with only PTSD and controls.

Psychological consequences of the Kegworth air disaster

BACKGROUND

The study sought to quantify psychiatric morbidity among survivors of a major air crash and to identify aetiological factors linked with post-traumatic stress disorder (PTSD).

METHOD

Sixty-eight of the 79 survivors (86%) were assessed at a clinical interview within one year of the disaster. The majority also completed the General Health Questionnaire, the Impact of Events Scale (IES) and the Zung Anxiety and Depression Scales.

RESULTS

Fifty-four of the study group (79%) met DSM-III-R criteria for a psychiatric disorder within one year of the disaster, of whom 27 (50%) had PTSD. Those who saw injured or dead people at the scene, or had sustained less severe injuries as measured by their Injury Severity Scores, or were under 35 years old, were significantly more likely to develop PTSD.

CONCLUSIONS

High rates of psychiatric morbidity are found in survivors of transportation disasters. Further studies are needed to identify those at most risk and to evaluate the benefits of psychological intervention.

Survivors' trauma and departmental response following deaths of police officers

It was hypothesized that satisfaction with supportive reactions of the police department following the on-duty death of an officer helps to ameliorate traumatic stress in surviving spouses. This hypothesis is based on the premise that the police-work group is cohesive and provides a psychological safety net for the surviving spouse. A secondary analysis was conducted of data obtained from 162 surviving police spouses. Analysis indicated that spouses' reported satisfaction with the department was significantly associated with lower trauma stress scores. These findings suggest that police departments should formulate policy to provide assistance to spouses surviving duty-related police deaths.

Comorbidity of psychiatric diagnoses with posttraumatic stress disorder in survivors of childhood trauma

OBJECTIVE

This study examines posttraumatic stress disorder (PTSD) symptoms, trauma exposure, gender, and diagnostic comorbidity in a sample of 59 Cambodian young adults (29 male and 30 female) who survived massive trauma as children.

METHOD

Psychiatric diagnoses were made using the Structured Clinical Interview for DSM-III-R-Non-Patient version, a structured diagnostic interview, and trauma exposure was measured with a Traumatic Life Events Questionnaire.

RESULTS

A significant number of those with PTSD (59%) had one or more additional DSM-III-R Axis I disorders. Major depression and generalized anxiety disorder were the most common comorbid disorders. Somatoform pain disorder was also found to coexist with PTSD but only among females. Women were also found to have higher levels of both current and lifetime PTSD symptoms.

CONCLUSION

Trauma symptoms were related to exposure and exposure was related to age, but age was not related to symptoms. The findings suggest that the significant levels of comorbid diagnoses previously found to exist with PTSD in people traumatized as adults can be found among survivors of massive childhood trauma. Also, the rate of PTSD diagnoses found in this sample 15 years after the trauma of Pol Pot is comparable to findings previously reported in studies of Cambodian youths and shows that the effects of trauma experienced in childhood persist into early adulthood.

Recovered-memory therapy and robust repression: influence and pseudomemories

A subset of the psychotherapists practicing trauma-focused therapy predicate their treatment on the existence of a newly claimed, powerful form of repression that differs from repression as used in the psychoanalytic tradition and from amnesia in any of its recognized forms. Recovered-memory specialists assist patients to supposedly retrieve vast quantities of information (e.g., utterly new dramatic life histories) that were allegedly unavailable to consciousness for years or decades. We refer to the hypothesized mental mechanism as "robust repression" and call attention to the absence of evidence documenting its validity and to the differences between it and other mental mechanisms and memory features. No recovered-memory practitioner has ever published a full specification of the attributes of this mechanism. That is, the properties it would have to have for the narratives developed during therapy to be historically accurate to any significant degree. This article reports a specification of the properties of the robust repression mechanism based on interviews with current and former patients, practitioners' writings, and reports to researchers and clinicians. The spread of reliance on the robust repression mechanism over the past 20 years through portions of the clinical community is traced. While involved in therapy, patients of recovered-memory practitioners come to believe that they have either instantly repressed large numbers of discrete events or simultaneously repressed all information about abuse they may have endured for as long as a decade.(ABSTRACT TRUNCATED AT 250 WORDS)

Substance abuse and post-traumatic stress disorder comorbidity

This article reviews the extant literature on substance abusers with and without a comorbid diagnosis of post-traumatic stress disorder (PTSD) and reveals the discontinuity between clinical lore and empirical research. Included is an overview of PTSD-substance abuse theoretical models and comorbidity prevalence rates, as well as an evaluation of the comparative data on treatment outcome and psychosocial factors, such as coping skills, for PTSD versus non-PTSD substance abusers. In addition, we discuss the controversy surrounding sequential versus simultaneous treatment approaches for such 'dually-diagnosed' patients. We conclude by identifying gaps in current knowledge about the nature and impact of PTSD on substance abuse treatment outcome and outlining needs for future research.

Mental and physical health status in a community sample of New Zealand Vietnam War veterans

The data presented in this paper were obtained by a survey involving 573 New Zealand Vietnam veterans. It represents the first comprehensive report on the mental and physical health of a community sample of these ex-service personnel. Although most of these veterans were reasonably healthy for their age, a small proportion was substantially worse off than their Vietnam veteran peers, reporting relatively low levels of psychological wellbeing, relatively high levels of psychological distress and post-traumatic stress disorder, a greater number and severity of physical health symptoms, lower self-rated health status, and making more frequent contacts with health care providers.

Effect of the Gulf War on reactivation of adverse combat-related memories in Vietnam veterans

Symptoms of combat related posttraumatic stress disorder (PTSD) have been reported extensively in Vietnam veterans. A few of these studies have reported situations in which PTSD has been reactivated in veterans with a history of PTSD. The present study reports the effects of media coverage of the Gulf War on a community sample of New Zealand Vietnam veterans. Levels of PTSD, distress, and well-being were assessed before and after the outbreak of hostilities. Most veterans closely followed the media presentation of the war and reported revived memories of Vietnam. Increased memories of Vietnam were associated with higher levels of PTSD and distress. It is suggested that veterans have heightened susceptibility to combat related stimuli because of their previous combat experience and that these stimuli can reactivate PTSD symptoms and distress. Implications of this finding for other groups in the community who harbour residual PTSD effects are discussed.

Alcoholism and drug abuse in patients with PTSD

The combination of PTSD and substance abuse is both common and problematic. In this chapter we review the following questions: 1) What is the relationship between PTSD, Alcoholism, and Drug Abuse? 2) Can the general "dual diagnosis" literature be of help? 3) Is the phenomenology of PTSD combined with alcoholism and/or drug abuse either unique or specific? 4) Does current pathophysiologic data allow conceptualization of a neurobiological model of PTSD, alcoholism, and drug abuse? 5) Drawing on these ideas, on the limited treatment literature, and the "dual diagnosis" literature, can we develop rational assessment and treatment approaches? Available literature suggests that diagnoses can be validly applied to these patients; that the illnesses must be treated simultaneously as co-primary illnesses; that extreme psychological symptoms reduce the efficacy of alcoholism or drug abuse treatment; and that effective control of these symptoms improves treatment outcome.

Reliability and validity of a combat exposure index for Vietnam era veterans

The reliability and validity of a self-report measure of combat exposure are examined in a cohort of male-male twin pairs who served in the military during the Vietnam era. Test-retest reliability for a five-level ordinal index of combat exposure is assessed by use of 192 duplicate sets of responses. The chance-corrected proportion in agreement (as measured by the kappa coefficient) is .84. As a measure of criterion-related validity, the combat index is correlated with the award of combat-related military medals ascertained from the military records. The probability of receiving a Purple Heart, Bronze Star, Commendation Medal and Combat Infantry Badge is associated strongly with the combat exposure index. These results show that this simple index is a reliable and valid measure of combat exposure.
