The relationship between acute stress disorder and posttraumatic stress disorder following cancer

In this study, the authors investigated the relationship between acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) following cancer diagnosis. Patients who were recently diagnosed with 1st onset head and neck or lung malignancy (N=82) were assessed for ASD within the initial month following their diagnosis and reassessed (n=63) for PTSD 6 months following their cancer diagnosis. At the initial assessment, 28% of patients had ASD, and 32% displayed subsyndromal ASD. At follow-up, PTSD was diagnosed in 53% of patients who had been diagnosed with ASD and in 11% of those who had not met criteria for ASD; 36% of patients with PTSD did not initially display ASD. In this study, the authors question the use of the ASD diagnosis to identify recently diagnosed patients at risk of PTSD.     

The relationship between acute stress disorder and posttraumatic stress disorder: a 2-year prospective evaluation

Previous research established that 78% of a sample of motor vehicle accident survivors initially diagnosed with acute stress disorder (ASD) were subsequently diagnosed with posttraumatic stress disorder (PTSD) at 6 months posttrauma. Although the previous study provided initial evidence for the utility of the ASD diagnosis, the relationship between ASD and PTSD was assessed over a relatively short period. The present study reassessed that original sample 2 years following the trauma to establish the longer term relationship between ASD and PTSD. ASD was diagnosed in 13% of participants, and 21% were diagnosed with subsyndromal ASD. In terms of participants who participated in all 3 assessments, 63% who met the criteria for ASD, 70% who met the criteria for subsyndromal ASD, and 13% who did not meet the criteria for ASD were diagnosed with PTSD at 2 years posttrauma. These findings indicate the importance of considering multiple pathways to the development of PTSD.     

Posttraumatic Stress Disorder Among Mothers of Pediatric Cancer Survivors: Diagnosis, Comorbidity, and Utility of the PTSD Checklist as a Screening Instrument

Objective: To examine posttraumatic stress disorder (PTSD) inmothers of survivors of childhood cancer. Comorbidity of anxietyand depressive disorders, prevalence of subclinical PTSD, andthe utility of a self report measure as a screening instrumentfor PTSD were also investigated. Method: Mothers (n = 65) completed a questionnaire self-reportPTSD checklist (PCL-C). Mothers were administered several modulesof the SCID: nonpatient edition by telephone, including thePTSD, Generalized Anxiety, and Major Depressive Disorder modules. Results: We diagnosed 6.2% of the sample with current PTSD.An additional 20% had subclinical PTSD. One of four motherswith PTSD diagnoses had a comorbid diagnosis of an anxiety anddepressive disorder. The PCL-C evidenced diagnostic utilityas a screening instrument. However, a moderate number of false-positiveswould result if the recommended cut-off on the instrument wasused. Conclusions: The PCL-C had diagnostic utility in screening mothersof childhood cancer survivors. The presence of comorbid diagnosessuch as anxiety and depression should be examined.     

Childhood physical and sexual abuse and subsequent depressive and anxiety disorders for two American Indian tribes

BACKGROUND: This study examined the relationship of childhood abuse, both physical and sexual, with subsequent lifetime depressive and anxiety disorders--depression or dysthymia, post-traumatic stress disorder (PTSD), and panic or generalized anxiety disorder (GAD)--among American Indians (AIs). METHOD: Three thousand and eighty-four AIs from two tribes--Southwest and Northern Plains--participated in a large-scale, community-based study. Participants were asked about traumatic events and family history, and were administered standard diagnostic measures of depressive/anxiety disorders. RESULTS: Prevalence of childhood physical abuse was approximately 7% for both tribes. The Southwest tribe had higher prevalence of depressive and anxiety disorders, with rates of PTSD being the highest. Childhood physical abuse was significant in bivariate models of depressive/anxiety disorders, and remained so in the multivariate models. CONCLUSIONS: Childhood physical abuse was a significant predictor of all disorder groups for males in both tribes except for panic/GAD for the Northern Plains tribe in multivariate models; females showed a more varied pattern. Childhood sexual abuse did not significantly differ for males and females, and was an independent predictor of PTSD for both tribes, controlling for childhood physical abuse and other factors, and was significant for the other disorder groups only in the Southwest. Additional covariates that increased the odds of depressive/anxiety disorder, were adult physical or sexual victimization, chronic illness, lifetime alcohol or drug disorder, and parental problems with depression, alcohol, or violence. Results provided empirical evidence of childhood and later life risk factors and expanded the population at risk to include males.     

An examination of the structure of posttraumatic stress disorder in relation to the anxiety and depressive disorders

The nature and structure of posttraumatic stress disorder (PTSD) has been the subject of much interest in recent times. This research has been represented by two streams, the first representing a substantive body of work which focuses specifically on the factor structure of PTSD and the second exploring PTSD's relationship with other mood and anxiety disorders. The present study attempted to bring these two streams together by examining structural models of PTSD and their relationship with dimensions underlying other mood and anxiety disorders. PTSD, anxiety and mood disorder data from 989 injury survivors interviewed 3-months following their injury were analyzed using a series of confirmatory factor analyses (CFA) to identify the optimal structural model. CFA analyses indicated that the best fitting model included PTSD's re-experiencing (B1-5), active avoidance (C1-2), and hypervigilance and startle (D4-5) loading onto a Fear factor (represented by panic disorder, agoraphobia and social phobia) and the PTSD dysphoria symptoms (numbing symptoms C3-7 and hyperarousal symptoms D1-3) loading onto an Anxious Misery/Distress factor (represented by depression, generalized anxiety disorder and obsessive compulsive disorder). The findings have implications for informing potential revisions to the structure of the diagnosis of PTSD and the diagnostic algorithm to be applied, with the aim of enhancing diagnostic specificity.     

Brief report: the risk of posttraumatic stress disorder in mothers of children diagnosed with pediatric cancer and type I diabetes

OBJECTIVE: To evaluate the risk of and predictors of enduring and late-onset posttraumatic stress disorder (PTSD) among mothers of children diagnosed with type I diabetes and cancer. METHOD: Mothers (N = 99) of children diagnosed with cancer or diabetes for at least 12 months completed a structured clinical interview for PTSD and self-report measures of PTSD, depression, anxiety, and stressful life events. RESULTS: There was no significant difference in the rate of PTSD between the two groups. Overall, fewer mothers (7%) met criteria for PTSD on the structured clinical interview than those on a self-report measure of PTSD (17%). Mothers who reported more depressive symptoms, anxiety, and stressful life events tended to report significantly more PTSD symptoms. CONCLUSIONS: The findings extend prior research regarding the prevalence rate and predictors of PTSD and PTSD symptoms in pediatric populations. It is recommended that clinicians exercise caution when interpreting prevalence rates for PTSD that are derived from self-report measures.     

Early predictors of chronic post-traumatic stress disorder in assault survivors

BACKGROUND: Some studies suggest that early psychological treatment is effective in preventing chronic post-traumatic stress disorder (PTSD), but it is as yet unclear how best to identify trauma survivors who need such intervention. This prospective longitudinal study investigated the prognostic validity of acute stress disorder (ASD), of variables derived from a meta-analysis of risk factors for PTSD, and of candidate cognitive and biological variables in predicting chronic PTSD following assault. METHOD: Assault survivors who had been treated for their injuries at a metropolitan Accident and Emergency (A&E) Department were assessed with structured clinical interviews to establish diagnoses of ASD at 2 weeks (n=222) and PTSD at 6 months (n=205) after the assault. Candidate predictors were assessed at 2 weeks. RESULTS: Most predictors significantly predicted PTSD status at follow-up. Multivariate logistic regressions showed that a set of four theory-derived cognitive variables predicted PTSD best (Nagelkerke R2=0.50), followed by the variables from the meta-analysis (Nagelkerke R2=0.37) and ASD (Nagelkerke R2=0.25). When all predictors were considered simultaneously, mental defeat, rumination and prior problems with anxiety or depression were chosen as the best combination of predictors (Nagelkerke R2=0.47). CONCLUSION: Questionnaires measuring mental defeat, rumination and pre-trauma psychological problems may help to identify assault survivors at risk of chronic PTSD.     

Psychiatric and psychosocial outcome of orthotopic liver transplantation

BACKGROUND: The study aimed to explore the prevalence of psychiatric disorders among orthotopic liver transplantation (OLT) recipients, and to investigate how psychiatric morbidity was linked to health-related quality of life (HRQOL). METHODS: We recruited 75 patients who had undergone OLT a median of 3.8 years previously (range = 5-129 months). Psychiatric morbidity was assessed using the Structural Clinical Interview for the DSM-III-R. Psychometric observer-rating and self-rating scales were administered to evaluate cognitive functioning (SKT), depressive symptomatology (HAMD(17)), posttraumatic stress symptoms (PTSS-10), social support (SSS), and HRQOL (SF-36 Health Status Questionnaire). Treatment characteristics were obtained from medical records. RESULTS: 22.7% (n = 17) of our sample had a current or probable psychiatric diagnosis according to DSM-III-R: 2.7% full posttraumatic stress disorder (PTSD) (n = 2), 2.7% major depressive disorder (MDD) comorbid to full PTSD (n = 2), 1.3% MDD comorbid to partial PTSD (n = 1), and 16% partial PTSD (n = 12). Patients with PTSD symptoms demonstrated lower cognitive performance, higher severity of depressive symptoms and more unfavorable perception of social support. OLT-related PTSD symptomatology was associated with maximal decrements in HRQOL. The duration of intensive care treatment, the number of medical complications, and the occurrence of acute rejection were positively correlated with the risk of PTSD symptoms subsequent to OLT. CONCLUSION: OLT-related PTSD symptomatology impairing HRQOL is a complication for a subgroup of OLT recipients. Health-care providers should be aware of the possible presence of PTSD in OLT survivors.     

A prospective study of autobiographical memory and posttraumatic stress disorder following cancer

In this study, the authors investigated the relationship between autobiographical memory and the onset and maintenance of distressing memories following cancer. In Study 1, participants recently diagnosed with head, neck, or lung cancer were assessed for acute stress disorder (ASD). Participants with ASD reported fewer specific memories than did participants without ASD. In Study 2, the same participants were assessed 6 months later for autobiographical memory and cancer-related posttraumatic stress disorder (PTSD). Deficits in the retrieval of specific memories in Study 1 were not predictive of subsequent PTSD. Increased hopelessness during the 6 months was associated with a decline in the retrieval of positive memories and an increase in the retrieval of negative memories. These findings accord with propositions that retrieval of distressing memories is guided by current self-image and attitude toward one's future.     

An 18-month longitudinal study of posttraumatic disorders in children who were taken hostage in their school

OBJECTIVE: The objective of our investigation was to study the course of direct and indirect posttraumatic disorders over 18 months in children after they were taken hostage in their school. METHODS: Twenty-six young hostages were evaluated by using standardized clinical interviews and self-administered questionnaires (State and Trait Anxiety Inventory for Children [STAIC]and Revised Impact of Event Scale [IES]) 2, 4, 7, and 18 months after the event. They were compared with 21 children from the same school who were not taken hostage (indirect exposure). RESULTS: Symptoms of acute stress were observed in 25 (96%) of the children who were directly involved in the traumatic event. After 2 months, 18 children had developed disorders according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, including 7 cases of full posttraumatic stress disorder (PTSD), 11 cases of subclinical PTSD, 3 cases of separation anxiety, 1 case of specific phobia, and 2 cases of major depressive disorder. Anxiety scores (STAIC) decreased between 2 and 4 months and then stabilized, whereas symptoms of avoidance (IES-avoidance) decreased gradually throughout the follow-up period, and symptoms of repetition (IES-intrusion) decreased less markedly. Children who were indirectly exposed to the trauma also manifested protracted posttraumatic symptomatology (two full cases of PTSD and six cases of subclinical PTSD), but their IES-intrusion scores were significantly lower at 7 months than those of children who were directly exposed, and the severity of their symptoms diminished over time. Girls tended to show a higher level of anxiety and more features of intrusion than boys. Psychological debriefing did not prevent occurrence of the disorders, but children who were not debriefed had the worst outcomes. CONCLUSIONS: Even after a short event and even if they are not directly exposed, children under the age of 9 years can develop high rates of posttraumatic disorders that follow a protracted course despite early intervention and careful monitoring.     

Effects of posttraumatic stress disorder on pregnancy outcomes

BACKGROUND: The purpose of this study was to determine the association between posttraumatic stress disorder (PTSD), diagnosed prospectively during pregnancy, and the risk of delivering a low birth weight (<2500 g) or preterm (<37 weeks gestational age) infant. METHODS: Pregnant women were recruited from obstetrics clinics and screened for major and minor depressive disorder, panic disorder, PTSD, and substance use. Current episodes of PTSD were diagnosed according to the MINI International Neuropsychiatric Interview, and pregnancy outcomes were abstracted from hospital records. RESULTS: Among the 1100 women included in analysis, 31 (3%) were in episode for PTSD during pregnancy. Substance use in pregnancy, panic disorder, major and minor depressive disorder, and prior preterm delivery were significantly associated with a diagnosis of PTSD. Preterm delivery was non-significantly higher in pregnant women with (16.1%) compared to those without (7.0%) PTSD (OR=2.82, 95% C.I. 0.95, 8.38). Low birth weight (LBW) was present in 6.5% of women and was not significantly associated with a diagnosis of PTSD in pregnancy after adjusting for potential confounders. However, LBW was significantly associated with minor depressive disorder (OR=1.82, 95% C.I. 1.01, 3.29). LIMITATIONS: There was a low prevalence of PTSD in this cohort, resulting in limited power. CONCLUSIONS: These data suggest a possible association between PTSD and preterm delivery. Coupled with the association found between LBW and a depressive disorder, these results support the utility of screening for mental health disorders in pregnancy.     

Reported trauma, post-traumatic stress disorder and major depression among primary care patients.

BACKGROUND: Trauma is a necessary diagnostic criterion for post-traumatic stress disorder (PTSD). However, the nature of traumas experienced (e.g. assaultive versus non-assaultive) may influence whether any mental disorder will arise. Traumatic experiences may also be associated with other mental disorders, particularly major depressive disorder (MDD). This report examines the relationship of trauma history to the likelihood of full or partial PTSD and MDD. In addition, the study examines the frequency with which assaultive and non-assaultive traumas are reported by patients with full or partial PTSD and MDD. METHODS: Three hundred eighty-six primary care patients completed psychiatric symptom measures during their clinic visit. A subset of 132 participants completed a diagnostic interview within 2 weeks following the screening. RESULTS: Most patients reporting traumas did not meet criteria for a mental disorder. Patients reporting traumas were more likely to experience current MDD (27.8%) than current full or partial PTSD (20.0%) although a high percentage of patients with traumas (41.1%) had experienced full or partial PTSD diagnosis in their lifetime. Respondents reporting assaultive events as their most severe trauma, when compared with those whose most severe trauma was non-assaultive, were more likely to have met criteria for either full or partial PTSD in their lifetime, and were more likely to have current MDD. CONCLUSIONS: These findings suggest that trauma history is often not associated with psychopathology, and when it is, trauma is often associated with major depression rather than PTSD. The likelihood of psychopathology is increased for individuals reporting assaultive traumas.     

Posttraumatic stress symptoms in parents of children with acute burns

OBJECTIVE: To develop a model of risk factors for posttraumatic stress disorder (PTSD) symptoms in parents of children with burns. METHODS: Immediately following the burn and 3 months later, parents reported on their children's and their own psychological functioning and traumatic stress responses. RESULTS: Approximately 47% of the parents reported experiencing significant posttraumatic stress symptoms 3 months after the burn. Our model indicates three independent pathways to PTSD symptoms (i.e., parent-child conflict, parents' dissociation, and children's PTSD symptoms). Additionally, parents' anxiety predicted increased parent-child conflict, conflict with extended family and size of the burn predicted parents' dissociation, and size of the burn and children's dissociation predicted children's PTSD symptoms. CONCLUSIONS: This study suggests that many parents of children with burns suffer from posttraumatic stress symptoms. Interventions that target factors such as family conflict, children's symptoms, and parents' acute anxiety and dissociation may diminish the risk for PTSD.     

Violence and risk of PTSD,major depression,substance abuse/dependence,and comorbidity: results from the National Survey of Adolescents

With a national household probability sample of 4,023 telephone-interviewed adolescents ages 12-17, this study provides prevalence, comorbidity, and risk-factor data for posttraumatic stress disorder (PTSD), major depressive episode (MDE), and substance abuse/dependence (SA/D). Roughly 16% of boys and 19% of girls met criteria for at least 1 diagnosis. Six-month PTSD prevalence was 3.7% for boys and 6.3% for girls, 6-month MDE prevalence was 7.4% for boys and 13.9% for girls, and 12-month SA/D prevalence was 8.2% for boys and 6.2% for girls. PTSD was more likely to be comorbid than were MDE and SA/D. Results generally support the hypothesis that exposure to interpersonal violence (i.e., physical assault, sexual assault, or witnessed violence) increases the risk of these disorders and of diagnostic comorbidity.     

Major depression in patients with panic disorder: factors associated with course and recurrence

The relationship between anxiety and depressive disorders has been the subject of considerable interest and controversy. In this study, the occurrence and course of affective illness was systematically examined in 63 patients meeting DSM-III-R criteria for panic disorder. Forty (63%) of the patients had experienced at least one major depressive episode. Of these, 13 (32.5%) experienced their first depressive episode prior to the onset of panic disorder, 15 (37.5%) experienced their first depressive episode after the onset of panic disorder, and in 12 (30.0%) the onset of the disorders was concurrent. Patients with agoraphobia had comparable rates of depression (68%) to patients without agoraphobia (53%, P = NS), and they had similar temporal patterns of depressive illness. Comorbidity with social phobia was associated with an increased longitudinal likelihood of major depression compared to patients without this comorbid diagnosis (P less than 0.05). Patients with longer duration of illness, early onset depression, melancholic depression, or family histories of anxiety or depression had an increased likelihood of having experienced recurrent depression. These findings are discussed in the context of current theories regarding the development of affective illness in patients with anxiety disorders.     

Elevated circulatory level of GABA(A)--antagonistic neurosteroids in patients with combat-related post-traumatic stress disorder

BACKGROUND: Post-traumatic stress disorder (PTSD) is a multisystem neurobiological disorder with chronic alterations in various neurochemical systems. Levels of the GABA(A)--antagonistic neurosteroids plasma dehydroepiandrosterone (DHEA) and its sulphate derivate, dehydroepiandrosterone sulphate (DHEAS) may be relevant to depressive and anxiety disorders, including PTSD. METHODS: We assessed the circulatory levels of morning plasma DHEA and DHEAS in 21 male outpatients with untreated chronic combat-related PTSD (CR-PTSD), and 18 healthy control male subjects. RESULTS: Compared with the control subjects, the PTSD patients showed significantly higher plasma DHEA and DHEAS levels. CONCLUSIONS: Chronic CR-PTSD may be associated with increased circulatory level of neuroactive steroids with inhibitory activity at the GABA(A) receptors. Neurosteroid-induced decreased GABAergic tone may be relevant to the symptomatology and pathophysiology of chronic PTSD, as well as to the frequent co-morbidity of PTSD with depression and anxiety disorders.     

Anxiety and depression in a community sample: the influence of comorbidity on social functioning

The main aim of the present study was to examine whether the well-established association between depression and social dysfunction still remains when effects of a coexistent anxiety disorder are eliminated from the data. As these effects strongly depend on the proportion of depressed subjects suffering simultaneously from an anxiety disorder, we first examined the frequency of mixed and pure depressive disorders and that of pure anxiety disorders (control subjects) in a community sample (n = 483). Using DIS/DSM-III criteria (reference period 6 months), pure anxiety disorders were most frequent (6%), followed by pure depressive disorders (3%) and the coexistence of anxiety and depression (2%). Cases suffering from both disorders were most severely afflicted in terms of psychopathology (persistence of symptoms, comorbidity regarding other mental disorders). At the diagnostic level, the association between depression and social dysfunction was only slightly influenced by effects resulting from comorbidity; at the level of actual symptoms, however, we found that cases suffering simultaneously from severe depression and severe anxiety were significantly more handicapped in their social lives than depressive subjects with only mild anxiety symptoms.

Can PTSD Occur with Amnesia for the Precipitating Event?

Theoretical accounts of post-traumatic stress disorder (PTSD) suggest that memory for a precipitating event is crucial for its development. Indeed, Sbordone and Liter (1995) have recently argued that mild traumatic brain injury and PTSD are mutually exclusive disorders. A case is described who sustained a severe head injury in a road traffic accident. He had a retrograde amnesia of two days and a post-traumatic amnesia of four weeks. Six months after his accident he was found to be suffering from a number of anxiety symptoms, including nightmares and intrusive thoughts, consistent with a diagnosis of PTSD. The implications of this case for theories of PTSD are discussed.
