The phenomenology of posttraumatic stress disorders following a natural disaster

This study examined the utility of the DSM-III diagnostic criteria for posttraumatic stress disorder (PTSD) in a high-risk group of 50 firefighters who had had an intense exposure to a natural disaster 8 months before being interviewed. Follow-up over the next 3 years allowed examination of the ability of these diagnostic criteria to predict a pattern of chronic posttraumatic morbidity. They predicted a pattern of chronic disorder, demonstrated by the finding that eight of the 15 subjects who had definite or borderline PTSD at 8 months remained symptomatic 3 years later. A disturbance of attention and concentration appeared to be the best predictor of chronic PTSD. The longitudinal course of posttraumatic morbidity in these 50 firefighters was compared with a matched group of 96 uninterviewed subjects 11 and 29 months after the disaster. Although the interview provoked an emotional catharsis in a number of firefighters, the long-term morbidity in the two groups was comparable. Fourteen subjects who did not have PTSD continued to experience intense imagery 8 months after the disaster. This observation raises questions about whether such thoughts and feelings have adequate specificity as diagnostic criteria for PTSD in a group that has recently been exposed to a traumatic event.     

Acute stress disorder, posttraumatic stress disorder, and depression in disaster or rescue workers

OBJECTIVE: The events of Sept. 11, 2001, highlighted the importance of understanding the effects of trauma on disaster workers. To better plan for the health care of disaster workers, this study examined acute stress disorder, posttraumatic stress disorder (PTSD), early dissociative symptoms, depression, and health care utilization in disaster workers. METHOD: Exposed disaster workers (N=207) and unexposed comparison subjects (N=421) were examined at 2, 7, and 13 months after an airplane crash. RESULTS: Exposed disaster workers had significantly higher rates of acute stress disorder, PTSD at 13 months, depression at 7 months, and depression at 13 months than comparison subjects. Those who were younger and single were more likely to develop acute stress disorder. Exposed disaster workers with acute stress disorder were 3.93 times more likely to be depressed at 7 months. Those with high exposure and previous disaster experience or who had acute stress disorder were more likely to develop PTSD. Similarly, those who were depressed at 7 months were 9.5 times more likely to have PTSD. Those who were depressed at 13 months were 7.96 times more likely to also meet PTSD criteria. More exposed disaster workers than comparison subjects obtained medical care for emotional problems at 2, 7, and 13 months. Overall, 40.5% of exposed disaster workers versus 20.4% of comparison subjects had acute stress disorder, depression at 13 months, or PTSD. CONCLUSIONS: Exposed disaster workers are at increased risk of acute stress disorder, depression, or PTSD and seek care for emotional problems at an increased rate.     

Lifetime comorbidity of antisocial personality disorder and anxiety disorders among adults in the community

The association between lifetime anxiety disorders, conduct disorder (CD), and antisocial personality disorder (ASPD) among adults in the community was explored. Data were drawn from the National Comorbidity Survey (n = 5,877), a representative community sample of adults aged 15-54 in the 48 contiguous US states. Multiple logistic regression analyses were used to determine the association between anxiety disorders, CD and ASPD, and between the co-occurrence of anxiety disorders and ASPD in the likelihood of comorbid substance use and affective disorders, suicidal ideation (SI) and suicide attempt (SA). Out of the 3.3% of adults with ASPD, over half (54.33%) had a comorbid anxiety disorder (lifetime). Similarly, 42.31% of adults with a history of CD (9.4%) who did not meet criteria for ASPD had a lifetime anxiety disorder. Social phobia [OR = 1.65 (1.01, 2.7)] and post-traumatic stress disorder [OR = 2.28 (1.3, 4.0)] were associated with significantly increased odds of ASPD, after adjusting for differences in sociodemographic characteristics and other psychiatric comorbidity. Major depression was no longer significantly associated with ASPD after adjusting for anxiety disorders. The comorbidity of anxiety disorders and ASPD was associated with significantly higher odds of major depression, substance use disorders, and SI and SA compared with odds among those without both disorders. These data provide initial evidence of an association between PTSD and social phobia and an increased likelihood of ASPD among adults in the community, after adjustment for comorbid affective and substance use disorders. Adults with ASPD and comorbid anxiety had significantly higher levels of comorbid major depression, alcohol dependence, and substance dependence and substantially higher rates of lifetime suicidal ideation and suicide attempts compared to adults with ASPD or anxiety disorders alone or with neither disorder. Future studies are needed to replicate this finding using longitudinal data and to investigate the possible mechanisms of the observed links between anxiety disorders and ASPD.     

Mental health problems among children and adolescents experiencing two major earthquakes in remote mountainous regions: A longitudinal study

ObjectiveMillions of children were exposed to major earthquake in China, with serious psychological and developmental consequences. To obtain accurate rate of post-disaster related disorder and identify predictors may help inform post-disaster rescue and rehabilitation efforts. The present longitudinal study explored correlations of demographic and socioeconomic characteristics of juvenile survivors of the Ya'an and Wenchuan earthquakes in China with their trajectories of post-disaster related disorder.MethodsA total of 435 Chinese children and adolescents who survived the 2013 Ya'an earthquake were recruited from six primary, secondary and high schools in Baoxing County. All survivors were assessed at 12 months after the disaster, when a trained psychiatrist assessed mental health problems in a face-to-face structured interview, and 153 survivors were followed up at 30 months after the earthquake via telephone.ResultsThe 12-month assessment indicated a post-traumatic stress disorder (PTSD) prevalence of 43.9% as well as depression (20.9%) or the criteria for both PTSD and depression (18.2%) and the other disorder (0.9%). The 30-month assessment indicated that 15.7% of subjects met the criteria for PTSD, 21.6% met the criteria for depression. No subjects met the criteria for other affective or anxiety disorders. Significant predictors of PTSD and depression were death in the family, previous earthquake experience, a poor parent–child relationship and economic pressure or poverty.LimitationsClinical interview face to face is quite different from via telephone and the attrition rate in the longitudinal cohort is high, which would directly affect our results of the assessment.ConclusionsPTSD and depression may be as prevalent and persistent in disaster victims in China as elsewhere, and high co-comorbidities remain poorly understood. Although many adolescents recover over time, some exhibit chronic, delayed-onset PTSD and depression, especially those with poor relationships with their parents or those living in precarious economic conditions. Family-based therapy may be needed to support child and adolescent trauma survivors in order to prevent mental illness.     

Avoidance and intrusion in posttraumatic stress disorder.

Longitudinal data from 290 firefighters who had completed questionnaires 4, 11, and 29 months after exposure to a natural disaster were used to examine the role of intrusive and distressing memories in the etiology of posttraumatic stress disorder. At 42 months, all those who were at risk of having developed a psychiatric disorder (N = 113) and a randomly selected comparison group (N = 34) who had never developed symptoms were interviewed using the Diagnostic Interview Schedule. The intrusion subscale score of the Impact of Events Scale accounted solely for the etiological link between the disaster and posttraumatic disorders. Avoidance had no direct relationship with the onset of symptoms and appeared to be a defensive strategy to contain the distress generated by the re-experiencing of the disaster, indicating the importance of separating these phenomena from disorder mood and arousal in posttraumatic stress disorder. An information processing model was validated using three different data sets, which suggests its robustness. Using cross-lagged panel correlations, a bidirectional relationship was demonstrated between disorder and intrusive recollections, suggesting that the intensity of recurring memories of a traumatic experience is as indicative of a disturbance of mood and arousal as the exposure to the trauma.     

Affective and anxiety disorders in the long-term follow-up of anorexia nervosa

This study investigated the incidence and onset of affective and anxiety disorders in women who were diagnosed with anorexia nervosa five to fourteen years earlier. Based on the clinical outcome of anorexia nervosa, patients were classified as asymptomatic, improved or symptomatic. Affective and anxiety disorders were assessed by a structured psychiatric interview (Diagnostic Interview Schedule). Results indicated that affective and anxiety disorders developed frequently, regardless of outcome of anorexia nervosa. Major depression and anxiety disorders developed before the eating disorder in one-half and three-quarters of these cases respectively. The symptomatic group had a significantly higher incidence of anxiety disorders prior to the development of their eating disorder compared with the asymptomatic group.     

Variability and severity of depression and anxiety in post traumatic stress disorder and major depressive disorder

In order to better characterize the similarities in and differences between the nature of the affective disturbance associated with Posttraumatic Stress Disorder (PTSD) and with Major Depressive Disorder (MDD), self-reported mood and anxiety ratings were examined in PTSD subjects, MDD subjects, and subjects without a psychiatric disorder while they were undergoing a chronobiologic study. Based on serial ratings on visual analogue scales over a 24 hr period, PTSD subjects showed comparable levels of depression as the MDD group, as measured by the mean and maximum levels of mood; however, they had greater mood variability, as measured by the range and coefficients of variation of the mood ratings. The MDD but not the PTSD group had significantly lower mood variability than the non-psychiatric group, as measured by the coefficients of variation. The PTSD group reported higher levels of anxiety than the non-psychiatric or MDD group but showed no differences in any measure of variability of anxiety. These findings suggest there are phenomenologic differences in the affective symptoms experienced by patients with PTSD and with MDD and that mood variability may distinguish between them.     

Prevalence of psychiatric disorder in a methadone maintenance population

OBJECTIVE: The objective of this study was to examine the prevalence of psychiatric disorders in a group of patients who had recently entered a methadone maintenance programme. METHOD: A total of 62 patients were interviewed using the Composite International Diagnostic Interview (CIDI) within 6 months of commencing methadone maintenance. The CIDI was used to establish symptoms of psychiatric illness at interview and in the 12 months prior. RESULTS: In the 12 months prior to interview, 76% of the sample fulfilled ICD-10 criteria for a psychiatric disorder other than substance-use disorder. Over half of the group interviewed fulfilled ICD-10 criteria for an affective disorder, two-thirds fulfilled criteria for an anxiety disorder and just under half fulfilled diagnostic criteria for both an affective disorder and an anxiety disorder in the 12 months prior to interview. At the time of interview, 19% fulfilled ICD-10 diagnostic criteria for a moderate or severe affective disorder. Seventy per cent of males and 89% of females interviewed had a comorbid psychiatric illness. In 71% of the group who had a comorbid psychiatric illness, the onset of psychiatric symptomatology was reported to predate the use of heroin. CONCLUSION: The prevalence of psychiatric disorder is up to 10 times higher in the population on methadone maintenance than in the general population and is two to three times higher than that found in community surveys of those with a substance-use disorder. These results are consistent with earlier findings and have implications for service planning.     

Long-term effects of political imprisonment: a group comparison study

The study investigated the long-term effects of political imprisonment in the former German Democratic Republic. A group of non-treatment-seeking former political prisoners (n=146) was compared with an age- and sex-matched group (n=75). Assessments included the structured Diagnostic Interview for Psychiatric Disorders (German abbreviation: DIPS) for DSM-III-R/IV diagnoses, a checklist of persecution and maltreatment, and other self-rated measures of post-traumatic stress disorder (PTSD), anxiety, depression, and dissociation. PTSD was assessed by the DIPS as current and lifetime diagnoses. Former political prisoners were imprisoned for 38 months on average. The former prisoners had a lower educational and lifetime occupational level than the comparison group. Results regarding diagnoses show a frequency of 30% current and 60% lifetime PTSD in the former prisoners group. Other anxiety disorders (e.g., claustrophobia, social phobia) outnumbered comorbid affective disorders. The level of dissociation was elevated in the former prisoners group. Intrusive recollections and hyperarousal were more common than avoidance/numbing symptoms. Despite differences in imprisonment duration between three historically defined eras of persecution, no differences appeared in the level of symptomatology. The results suggest that political imprisonment in the former German Democratic Republic had long-term psychological effects. Compared with an age-and sex-matched comparison group, the former political prisoners showed higher levels not only of post-traumatic symptomatology but also of other anxiety disorders and dissociation.     

Psychiatric morbidity in first time stroke patients in Hong Kong: a pilot study in a rehabilitation unit

OBJECTIVE: There is a paucity of data on post-stroke psychiatric morbidity in Chinese populations. We examined the frequency of post-stroke psychiatric morbidity in Chinese first time stroke patients, including depressive and anxiety disorders, mania, and psychosis. METHODS: One hundred and fifty-seven patients following their first stroke, who were consecutively admitted to a rehabilitation unit, participated in this prospective, cross-sectional study. All subjects were interviewed by a qualified psychiatrist using the SCID-DSM-III-R. Subjects' cognitive function, neurological status, and level of functioning were also measured. Twenty-five (92.6%) of the subjects with the diagnosis of depression were followed up 6.0 +/- 3.9 months after the initial assessment. RESULTS: The frequency of all depressive disorders was 17.2%. Major depressive episodes, adjustment disorder with depressed mood, dysthymia, and generalized anxiety disorder were diagnosed in 7.6%, 8.2%, 1.3% and 0.6% of the subjects, respectively. No cases of other anxiety disorders, mania or psychosis were found. The majority of depressed subjects were in remission at the follow-up assessment. CONCLUSION: The low morbidity of affective disorders and their relatively favourable short-term outcome in Chinese first time stroke patients warrants further investigation.     

Psychiatric morbidity and comorbidity following accidental man-made traumatic events: incidence and risk factors

The aims of this study were to examine the incidence and risk factors of major depression, bipolar disorder, psychoactive substance use, psychotic and anxiety disorders in relation to post-traumatic stress disorders (PTSD) in a study group exposed to two different traumatic events, i. e. 128 fire and 55 motor vehicle accident victims. Data have been collected 7–9 months after the traumatic event. The diagnosis of axis-I diagnoses, other than PTSD, was made according to DSM-III-R criteria using the Structured Interview according to the DSN-III-R. The incidence of new-onset major depression was 13.4%, generalised anxiety disorder (GAD) 12.6%, agoraphobia 10.2% and psychoactive substance use disorders 6%. Simple phobia, panic disorder and obsessive compulsive disorder had a much lower incidence (< 2.0%). Fifty-one percent of the victims with PTSD had one or more addition axis-I diagnoses, major depression (26.2%), agoraphobia (21.0%) and generalised anxiety disorder (24.6%) being the most common. Physical injury was the single best predictor for major depression. The best predictors for the development of new-onset anxiety disorders, other than PTSD, were: type and horror of the trauma, the extent of physical injury, the loss of control during the traumatic event, contextual stimuli, younger age and female sex. In conclusion: comorbid disorders, such as depression, GAD and agoraphobia, commonly occur within the first few months after man-made accidental traumata. Trauma variables, which are known to be related to the development of PTSD, are also related to the occurrence of these comorbid disorders. Received: 2 July 1999 / Accepted: 27 January 2000     

Impact of comorbid panic and posttraumatic stress disorder on outcomes of collaborative care for late-life depression in primary care.

OBJECTIVE: Comorbid anxiety disorders may result in worse depression treatment outcomes. The authors evaluated the effect of comorbid panic disorder and posttraumatic stress disorder (PTSD) on response to a collaborative-care intervention for late-life depression in primary care. METHODS: A total of 1,801 older adults with depression were randomized to a collaborative-care depression treatment model versus usual care and assessed at baseline, 3, 6, and 12 months, comparing differences among participants with comorbid panic disorder (N=262) and PTSD (N=191) and those without such comorbid anxiety disorders. RESULTS: At baseline, patients with comorbid anxiety reported higher levels of psychiatric and medical illness, greater functional impairment, and lower quality of life. Participants without comorbid anxiety who received collaborative care had early and lasting improvements in depression compared with those in usual care. Participants with comorbid panic disorder showed similar outcomes, whereas those with comorbid PTSD showed a more delayed response, requiring 12 months of intervention to show a significant effect. At 12 months, however, outcomes were comparable. Interactions of intervention status by comorbid PTSD or panic disorder were not statistically significant, suggesting that the collaborative-care model performed significantly better than usual care in depressed older adults both with and without comorbid anxiety. CONCLUSIONS: Collaborative care is more effective than usual care for depressed older adults with and without comorbid panic disorder and PTSD, although a sustained treatment response was slower to emerge for participants with PTSD. Intensive and prolonged follow-up may be needed for depressed older adults with comorbid PTSD.     

Lifetime history of traumatic events in a young adult Mexican American sample: Relation to substance dependence,affective disorder,acculturation stress,and PTSD

Mexican Americans comprise one of the most rapidly growing populations in the United States, and within this population, trauma and post-traumatic stress disorder (PTSD) are associated with physical and mental health problems. Therefore, efforts to delineate factors that may uniquely contribute to increased likelihood of trauma, PTSD, and substance use disorders over the lifetime in Mexican Americans are important to address health disparities and to develop treatment and prevention programs. Six hundred fourteen young adults (age 18–30 yrs) of Mexican American heritage, largely second generation, were recruited from the community and assessed with the Semi-Structured Assessment for the Genetics of Alcoholism and an acculturation stress scale. More males (51.2%) reported experiencing traumas than females (41.1%), however, a larger proportion of females received a PTSD diagnosis (15%) than males (8%). Alcohol dependence and affective disorders, but not anxiety disorders, antisocial disorders, nicotine, marijuana, or stimulant dependence, were significantly comorbid with PTSD. Endorsing higher levels of acculturation stress was also significantly associated with both trauma exposure and a diagnosis of PTSD. Logistic regression revealed that female gender, having an affective disorder, alcohol dependence, higher levels of acculturation stress, and lower levels of education were all predictors of PTSD status. Additionally, alcohol dependence generally occurred after the PTSD diagnosis in early adulthood in this high-risk population. These studies suggest that treatment and prevention efforts should particularly focus on young adult second generation Mexican American women with higher levels of acculturation stress, who may be at higher risk for PTSD, affective disorder, and alcohol dependence following trauma exposure.     

Sensitivity to carbon dioxide in drug-naïve subjects with post-traumatic stress disorder

Post-traumatic stress disorder (PTSD) is currently classified as an anxiety disorder in DSM-IV, and as a neurosis or stress-related disorder in ICD-10. It shares many features with depression. Sensitivity to carbon dioxide (CO2), a classic provocation agent in the proto-typical anxiety disorder, panic disorder, has not been tested in PTSD. Twenty rigorously ascertained drug-na?ve subjects with PTSD inhaled a single vital capacity inhalation of 35% CO2; before and after the inhalation they completed measures of PTSD and panic anxiety, and were rated for the presence of a panic attack. These results were retrospectively compared with those of 39 healthy volunteers and 17 patients with panic disorder previously studied by the same research group. PTSD symptoms were not exacerbated by CO2. Two out of twenty PTSD subjects panicked. PTSD subjects' responses were indistinguishable from those of healthy volunteers, and differed from those of subjects with panic disorder. The lack of sensitivity to carbon dioxide in PTSD subjects in the present study adds to the literature on the differences between PTSD and other anxiety disorders, and to that on the specificity of the CO2 challenge in panic disorder.     

Anxiety disorders in subjects seeking treatment for eating disorders: a DSM-IV controlled study

Women who were referred with an eating disorder (ED) were compared with a matched normal control group to answer the following questions: What are the frequencies of anxiety disorders in cases of anorexia and bulimia nervosa diagnosed according to DSM-IV criteria? Are anxiety disorders significantly more frequent among women with an eating disorder than among women from the community? We assessed the frequencies of six specific anxiety disorders among 271 women with a current diagnosis of anorexia or bulimia nervosa and 271 controls, using the Mini-International Neuropsychiatric Interview, French DSM-IV version. A lifetime comorbidity with at least one anxiety disorder was found in 71% of both the anorexic and the bulimic subjects, significantly higher than the percentage of controls with an anxiety disorder. The prevalence was significantly higher in the eating disorder groups than in controls for most types of anxiety disorder, and between 41.8 and 53.3% of comorbid cases had an anxiety disorder preceding the onset of the eating disorder. Anxiety disorders are significantly more frequent in subjects with eating disorders than in volunteers from the community, a finding that has important etiological and therapeutic implications.     

Posttraumatic stress disorder and psychiatric comorbidity among detained youths

OBJECTIVE: This study examined the prevalence of posttraumatic stress disorder (PTSD) and comorbid psychiatric disorders among juvenile detainees. METHODS: The sample consisted of a stratified random sample of 898 youths aged ten to 18 years who were arrested and detained in Chicago. RESULTS: Among participants with PTSD, 93% had at least one comorbid psychiatric disorder; however, among those without PTSD, 64% had at least one comorbid psychiatric disorder. Over half (54%) of the participants with PTSD had two or more types of comorbid disorders--that is, affective, anxiety, behavioral, or substance use disorders--and 11% had all four types of comorbid disorders. Among males, having any psychiatric diagnosis significantly increased the odds of having comorbid PTSD. Among females, alcohol use disorder and both alcohol and drug use disorders significantly increased the odds of having PTSD. No significant difference in prevalence rates of PTSD was found between males and females with specific psychiatric disorders. The prevalence of any comorbid psychiatric disorder was significantly greater for males with PTSD than that for females with PTSD (OR=3.4, CI=1.1-10.6, p<.05). CONCLUSIONS: Detection of comorbid PTSD among detained youths must be improved. PTSD is often missed because traumatic experiences are rarely included in standard screens or volunteered by patients. When planning treatment, clinicians must consider ramifications of comorbid PTSD.     

Traumatic events and posttraumatic stress disorder in an urban population of young adults

To ascertain the prevalence of posttraumatic stress disorder (PTSD) and risk factors associated with it, we studied a random sample of 1007 young adults from a large health maintenance organization in the Detroit, Mich, area. The lifetime prevalence of exposure to traumatic events was 39.1%. The rate of PTSD in those who were exposed was 23.6%, yielding a lifetime prevalence in the sample of 9.2%. Persons with PTSD were at increased risk for other psychiatric disorders; PTSD had stronger associations with anxiety and affective disorders than with substance abuse or dependence. Risk factors for exposure to traumatic events included low education, male sex, early conduct problems, extraversion, and family history of psychiatric disorder or substance problems. Risk factors for PTSD following exposure included early separation from parents, neuroticism, preexisting anxiety or depression, and family history of anxiety. Life-style differences associated with differential exposure to situations that have a high risk for traumatic events and personal predispositions to the PTSD effects of traumatic events might be responsible for a substantial part of PTSD in this population.     

Pharmacogenomics and therapeutic prospects in dementia

OBJECTIVE: To describe the prevalence and correlates of post-traumatic stress disorder (PTSD), depressive and anxiety disorders, or any other mental disorder among adult victims treated in a hospital at different points in time after the 11 March 2004 terrorist attacks in Madrid. DESIGN, SETTING, AND PARTICIPANTS: A random sample of 56 individuals injured in the attacks was interviewed in person at one, six, and twelve months after the attacks. MAIN OUTCOME MEASURES: Current DSM-IV mental disorders: depressive disorders and anxiety disorders (PTSD, generalised anxiety, agoraphobia, social phobia, and panic disorder) were assessed with the Spanish version of the MINI (Mini International Neuropsychiatric Interview), a structured, lay-administered psychiatric interview. RESULTS: PTSD was the most prevalent psychiatric disorder (35.7% at month 1, 34.1% at month 6, and 28.6% at month 12), followed by major depression (28.6%, 22.7%, and 28.6%, respectively). Others relevant conditions were suicide risk, generalised anxiety disorder (GAD), agoraphobia, and panic disorder. No significant differences in the prevalence of the disorders were found between the different assessment times. Patients with a psychiatric history prior to 11 March had a higher prevalence of PTSD, major depression, GAD, and panic disorder at month 1. Females had higher prevalence of PTSD, agoraphobia, and panic disorder at month 1. The only predictive factor for PTSD at month 12 was PTSD at month 6 (OR = 14.007). The only predictive factor for major depression at month 12 was major depression at month 6 (OR = 15.847). CONCLUSION: The prevalence of PTSD and major depression was high and remained stable between month 1, month 6, and month 12. The only predictive factor for PTSD at month 12 was PTSD at month 6.     

Lifetime and six-month prevalence of mental disorders in the Munich follow-up study

Summary The Lifetime and 6 month DSM-III prevalence rates of mental disorders from an adult general population sample of former West Germany are reported. The most frequent mental disorders (lifetime) from the Munich Follow-up Study were anxiety disorders (13.87%), followed by substance (13.51%) and affective (12.90%) disorders. Within anxiety disorders, simple and social phobia (8.01%) were the most common, followed by agoraphobia (5.47%) and panic disorder (2.39%). Females had about twice the rates of males for affective (18.68% versus 6.42%), anxiety (18.13% versus 9.07%), and somatization disorders (1.60% versus 0.00%); males had about three times the rates of substance disorders (21.23% versus 6.11%) of females. Being widowed and separated/divorced was associated with high rates of major depression. Most disordered subjects had at least two diagnoses (69%). The most frequent comorbidity pattern was anxietyand affective disorders. Simple and social phobia began mostly in childhood or early adolescence, whereas agoraphobia and panic disorder had a later average age of onset. The majority of the cases with both anxiety and depression had depression clearly after the occurrence of anxiety. The DIS-DSM-III findings of our study have been compared with both ICD-9 diagnoses assigned by clinicians independently as well as other epidemiological studies conducted with a comparable methodology.     

Posttraumatic stress symptoms in parentally bereaved children and adolescents

OBJECTIVE: To compare parentally bereaved children with a disaster comparison group and a nontrauma control group on measures of emotional adjustment. METHOD: Children and adolescents who had lost a parent (n = 39), had experienced a tornado disaster (n = 69), or were coping with an ongoing social or academic stressor (n = 118) completed measures of posttraumatic stress disorder (PTSD) symptoms, anxiety, and depression. Risk factors for symptoms among the bereaved children also were evaluated. RESULTS: Parentally bereaved children reported significantly more PTSD symptoms than the disaster and nontrauma control groups. Among the bereaved children, girls, younger children, and children living with a surviving parent who scored high on a measure of posttraumatic stress reported more symptoms. CONCLUSION: Children and adolescents who have lost a parent could be vulnerable to PTSD symptoms.
