Data on symptoms of posttraumatic stress disorder (PTSD) were collected 6 months after Hurricanes Paulina (N/&=/&200; Mexico) and Andrew (non-Hispanic n/&=/&270; United States) using the Revised Civilian Mississippi Scale. A 4-factor measurement model that represented the accepted multicriterion conceptualization of PTSD fit the data of the U.S. and Mexican samples equally well. The 4 factors of Intrusion, Avoidance, Numbing, and Arousal correlated significantly and equivalently with severity of trauma in each sample. A single construct explained much of the covariance of the symptom factors in each sample. However, modeling PTSD as a unidimensional construct masked differences between samples in symptom severity. With severity of trauma controlled, the Mexican sample was higher in Intrusion and Avoidance, whereas the U.S. sample was higher in Arousal. The results suggest that PTSD is a meaningful construct to study in Latin American societies. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Factor analytic studies of trauma victims' posttraumatic stress disorder (PTSD) have offered conflicting hypotheses about how to conceptualize PTSD into symptom categories. The present study used confirmatory factor analyses of self-reported PTSD symptomatology from 5,664 child and adolescent victims of Hurricane Hugo to compare 10 models of PTSD dimensionality. PTSD was best represented by a 2nd-order PTSD factor that manifests in 3 symptom clusters (Intrusion/Active Avoidance, Numbing/Passive Avoidance, and Arousal). This model was cross-validated on 3 age groups (late childhood, early adolescence, and late adolescence), and results indicated factorial invariance across groups. PTSD symptoms varied in relative centrality to the underlying dimensions of PTSD, which differed in their relations with anxiety and degree of traumatic exposure. Implications for classification criteria and an empirically supported theory of PTSD are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

OBJECTIVE: This study investigated hypotheses concerning the importance of symptoms of numbing in posttraumatic stress disorder (PTSD). METHODS: Symptoms of PTSD were assessed in 72 female rape victims and 86 female victims of nonsexual assault approximately 3 months after the crimes occurred. A principal-components factor analysis of subjects' symptoms was then undertaken. RESULTS: The analysis yielded three factors: arousal/avoidance, numbing, and intrusion. These were somewhat different from the symptom clusters in DSM-III-R, since effortful avoidance and numbing symptoms did not load on the same factor. Numbing symptoms appeared to be particularly important in identifying individuals with PTSD. CONCLUSIONS: The results imply that there are two patterns of posttrauma symptoms, one characterizing PTSD and the second characterizing a phobic reaction. 相似文献

This article describes the development and preliminary validation of the Morel Emotional Numbing Test for PTSD (MENT), a forced-choice test for detecting response bias in assessments for posttraumatic stress disorder (PTSD). The differences in MENT error rates among four groups of military veterans applying for monetary compensation for combat-related PTSD and two groups of hospitalized military veterans were investigated (N = 102): (a) disability claimants with veritable self-presentations, who were diagnosed with PTSD; (b) disability claimants with veritable self-presentations, who were not diagnosed with PTSD; (c) older disability claimants (age 63 or older) with veritable self-presentations; (d) disability claimants with suspect self-presentations; (e) chemical-dependent inpatients; and (f) schizophrenic inpatients. Veritable versus suspect grouping among disability claimants was determined by examining MMPI-2 F-K dissimulation index scores. The results indicated that the suspect group produced more errors on the MENT than the credible groups or the hospitalized patient groups (p < .0001). Clinical decision rules were used to evaluate the relative effectiveness of the MENT to identify malingering in the claimant groups. The overall efficiency or hit rate on the MENT was 95.6%. 相似文献

Although individuals with comorbid posttraumatic stress disorder (PTSD) and substance use diagnoses are at heightened risk for relapse after substance abuse treatment, little is known about the specific situations in which these individuals are likely to relapse. The present study was designed to test whether a PTSD diagnosis related to substance use in specific situations in which PTSD symptoms were likely to be present. Data were gathered from inpatients (n?=?86) in a substance-abuse treatment program, and relationships between PTSD diagnosis and frequency of substance use in high-risk situations were examined. As predicted, PTSD diagnosis was related to substance use in situations involving unpleasant emotions, physical discomfort, and interpersonal conflict, but not to substance use in other situations.

This review article presents several potential functional pathways which may explain the frequent co-occurrence of PTSD and substance abuse disorders in traumatized individuals. Emerging empirical studies which have examined these potential pathways are reviewed, including studies on relative order of onset, PTSD patients' perceptions of various drug effects, comparisons of PTSD patients with and without comorbid substance use disorders, and correlational studies examining the relations between severity of specific PTSD symptom clusters and substance disorder symptoms. Research on the acute and chronic effects of alcohol and other drugs on cognitive and physiological variables relevant to PTSD intrusion and arousal symptoms is reviewed to highlight ways in which these two sets of PTSD symptoms might be functionally interrelated with substance abuse. Finally, based on these findings, recommendations are made for the treatment of individuals with comorbid PTSD-substance use disorders. 相似文献

Sertraline treatment of comorbid posttraumatic stress disorder and alcohol dependence 总被引:1,自引:0,他引:1
BACKGROUND: Posttraumatic stress disorder (PTSD) often co-occurs with alcohol dependence, yet little is known about treatment of this comorbidity. The serotonin selective reuptake inhibitors have been shown preliminarily to be effective in decreasing symptoms of PTSD but have not been studied in individuals with comorbid alcohol dependence. This is of particular interest as the SSRIs also have a modest effect in decreasing alcohol consumption. METHOD: In this preliminary trial, nine subjects with comorbid PTSD and alcohol dependence were treated in an open-label trial with sertraline for a 12-week period. Symptoms of PTSD and depression were monitored monthly with the Impact of Event Scale and the Hamilton Rating Scale for Depression (HAM-D). Alcohol consumption was monitored by a self-report instrument (Time-Line Follow-Back). RESULTS: There were significant decreases in all three symptom clusters of PTSD measured by overall PTSD symptom scores (p < or = .001) and in HAM-D scores (p < or = .001) during the follow-up period. Days of abstinence increased and average number of drinks decreased during the follow-up period. Four subjects claimed total abstinence during the follow-up period. CONCLUSION: While limited by small sample size and the open-label, nonblinded study design, this study suggests that sertraline may be useful in the treatment of PTSD complicated by alcoholism. The medication was well tolerated and subjects showed improvement in PTSD symptoms as well as decreased alcohol consumption. A controlled trial of sertraline in this population would be of interest. 相似文献

The high rate of posttraumatic stress disorder (PTSD) among substance use disorder (SUD) patients has been documented in research protocols, but there is evidence that it is markedly under-diagnosed in clinical settings. To address the need for a brief self-report measure to identify SUD patients who may benefit from further assessment and/or treatment for PTSD, the psychometric properties of a modified version of the PTSD Symptom Scale Self-Report (PSS-SR) were examined in a treatment-seeking SUD sample (N = 118). The modified version of the PSS-SR, which measures both frequency and severity of PTSD symptoms, demonstrated good internal consistency reliability and was correlated with other self-report measures of trauma-related symptomatology. Comparisons between a structured PTSD diagnostic interview and the modified PSS-SR indicated that 89% of the PTSD positive patients were correctly classified by the modified PSS-SR. The clinical relevance of these findings was discussed. 相似文献

Investigators have recently identified a two-factor structure underlying posttraumatic stress symptoms through the use of exploratory factor analysis. [Taylor et al. (1988). The structure of posttraumatic stress symptoms. Journal of Abnormal Psychology, 107, 154-160]. These two factors, which were labeled as Intrusion and Avoidance, and Hyperarousal and Numbing, are consistent with current theoretical models of posttraumatic stress disorder--PTSD [e.g. Foa et al. (1992). Uncontrollability and unpredictability in post-traumatic stress disorder: An animal model. Psychological Bulletin, 112, 218-238]. However, the authors of the Taylor et al. study issued caution in interpreting their findings because there has yet to be a systematic replication of their results. This paper presents a confirmatory factor analysis of the two-factor structure of posttraumatic stress symptoms in 217 survivors of serious motor vehicle accidents with varying degrees of PTSD symptoms. A hierarchical, confirmatory-factor analysis conducted with a structural equation modeling statistics package confirmed that the model proposed by Taylor et al. can adequately account for the presentation of PTSD symptoms in this sample of motor vehicle accident survivors. The implications for the assessment and diagnosis of PTSD are discussed. 相似文献

To assess the clinical characteristics of women with posttraumatic stress disorder (PTSD) and substance dependence, 28 women with both disorders were compared with 29 women with PTSD alone on a wide battery of lifetime and current clinical measures. The dual-diagnosis women consistently had a more severe clinical profile, including worse life conditions (e.g., physical appearance, opportunities in life), both as children and as adults; greater criminal behavior; a higher number of lifetime suicide attempts; a greater number having a sibling with a drug problem; and fewer outpatient psychiatric treatments. One discrepant finding, however, was their lower rate of major depression. Interestingly, the 2 groups did not differ in number or type of lifetime traumas, PTSD onset or severity, family history of substance use; coping style, functioning level, psychiatric symptoms, or sociodemographic characteristics. Treatment implications and methodological limitations are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Abuse is a major source of trauma to women, and post-traumatic stress disorder (PTSD) results from exposure to extreme trauma. To describe the relationship between symptoms of PTSD and severity of abuse, an ethnically stratified cohort of 131 abused women in a primary care setting was interviewed. Symptoms of PTSD, both intrusion (i.e., trouble falling asleep, strong waves of feelings about the abuse) and avoidance (i.e., trying not to think or talk about the abuse, staying away from reminders of the abuse), were significantly (p < 0.01) correlated to severity of abuse, regardless of ethnicity. When asked about childhood physical or sexual abuse, women reporting physical abuse had significantly (p < 0.05) higher intrusion scores, whereas those reporting sexual abuse had significantly (p < 0.004) higher avoidance scores. Sixty-five percent of the women reported dreams, flashbacks, or terror attacks and had significantly (p < 0.001) higher mean results on both intrusion and avoidance. The need to offer abused women information about the connection between severity of abuse and symptoms of PTSD is discussed. We recommend that clinicians ask all abused women about dreams, flashbacks, or terror attacks to assess for further symptoms of PTSD. 相似文献

In the present study, the psychometric properties of the German version of the Posttraumatic Diagnostic Scale (PTDS; A. Ehlers, R. Steil, H. Winter, & E. B. Foa, 1996) were evaluated in a sample of 143 trauma survivors. To investigate convergent and discriminant validity of this questionnaire, the authors assessed posttraumatic stress disorder (PTSD), anxiety, depression symptoms, and social phobia. Internal consistencies of the PTDS and its subscales as well as their association with related measures show that the German PTDS is a reliable and valid instrument for the assessment of posttraumatic stress symptoms. A 3-factor structure was found that is, however, not exactly in concordance with the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; American Psychiatric Association, 2000) formulation (Reexperiencing, Avoidance, and Hyperarousal) but rather comprises a Reexperiencing/Avoidance factor; an Emotional Numbing/Hyperarousal factor; and a 3rd factor, consisting of Hypervigilance and an Exaggerated Startle Response. The findings are discussed with respect to their equivalency to the original PTDS, core symptoms of PTSD, and desirable future research.

This longitudinal study examined the contribution of anxiety/depressive symptoms and lifetime and recent trauma exposure to substance use after residential substance abuse treatment among individuals with co-occurring disorders. Data were collected from adults at treatment entry and 6 and 12 months later. At treatment entry, nearly all participants reported lifetime trauma exposure, and over one third met criteria for posttraumatic stress disorder (PTSD). Over the follow-up, nearly one third of the participants were exposed to trauma. Lifetime trauma exposure and a diagnosis of PTSD at treatment entry were not associated with substance use over the follow-up. Trauma exposure and anxiety/depressive symptoms over the follow-up were associated with an increased likelihood of substance use. Gender did not moderate the association between trauma exposure and anxiety/depressive symptoms and substance use. These findings highlight the importance of monitoring for trauma exposure and symptoms of anxiety/depression to better target interventions and continuing care approaches to reduce the likelihood of posttreatment substance use in this population.

Homeless women are at increased risk for problematic alcohol use and posttraumatic stress disorder (PTSD). While coping motives have been shown to mediate the relationship between PTSD symptoms and alcohol problems in victims of sexual assault and domestic violence, it is unknown whether this relationship is evident in other trauma-exposed populations. The focus of this study was to examine whether drinking to cope mediated the relationship between PTSD symptoms and current alcohol use in a group of homeless, ethnically diverse women. Twenty-three women were recruited from local shelters in a southwestern community and asked to complete measures assessing their current alcohol use, drinking motives, and PTSD symptoms. Results revealed that drinking to cope mediated the relationship between PTSD symptoms and current alcohol use. This finding supports the theory that homeless women may benefit from treatment interventions that address both their substance use and trauma issues.

The authors compared substance-dependent women with and without a comorbid diagnosis of posttraumatic stress disorder (PTSD) on their alcohol and drug use after inpatient substance abuse treatment. Participants were 31 women with a diagnosed substance dependence disorder. Forty-two percent of the entire sample (n?=?13) met DSM-III—R criteria for current PTSD. Follow-up interviews revealed that approximately 70% of the women relapsed during the 3 months posttreatment. Although rates of relapse did not significantly differ by PTSD status, PTSD women were found to relapse more quickly than non-PTSD women. Although preliminary, study findings suggest that the presence of PTSD among substance-dependent women may have prognostic significance as well as important treatment implications.

OBJECTIVE: This study analyzed questionnaire items that address complaints about sleep from the National Vietnam Veterans Readjustment Study, a nationally representative sample of the 3.1 million men and women who served in Vietnam. This study compared the frequency of nightmares and difficulties with sleep onset and sleep maintenance in male Vietnam theater veterans with male Vietnam era veteran and male civilian comparison subjects. It focused on the role of combat exposure, nonsleep posttraumatic stress disorder (PTSD) symptoms, comorbid psychiatric and medical disorder, and substance abuse in accounting for different domains of sleep disturbance. METHOD: The authors undertook an archival analysis of the National Vietnam Veterans Readjustment Study database using correlations and linear statistical models. RESULTS: Frequent nightmares were found exclusively in subjects diagnosed with current PTSD at the time of the survey (15.0%). In the sample of veterans who served in Vietnam (N = 1,167), combat exposure was strongly correlated with frequency of nightmares, moderately correlated with sleep onset insomnia, and weakly correlated with disrupted sleep maintenance. A hierarchical multiple regression analysis showed that in Vietnam theater veterans, 57% of the variance in the frequency of nightmares was accounted for by war zone exposure and non-sleep-related PTSD symptoms. Alcohol abuse, chronic medical illnesses, panic disorder, major depression, and mania did not predict the frequency of nightmares after control for nonsleep PTSD symptoms. CONCLUSIONS: Frequent nightmares appear to be virtually specific for PTSD. The nightmare is the domain of sleep disturbance most related to exposure to war zone traumatic stress. 相似文献

Combat-related posttraumatic stress disorder (PTSD) is linked with elevated psychological distress in service members'/veterans' spouses. Researchers use a variety of terms to describe this distress, and recently, secondary traumatic stress and secondary traumatic stress disorder (STS/STSD) have become increasingly commonly used. Although STS/STSD connotes a specific set of symptoms that are linked to service members'/veterans' symptoms, researchers often use general measures of distress or generically worded measures of PTSD symptoms to assess STS/STSD. To determine how often scores on such measures appear to be an accurate reflection of STS/STSD, we examined responses to a measure of PTSD symptoms in 190 wives of male service members with elevated levels of PTSD symptoms. Wives rated their own PTSD symptoms, and then answered questions about their attributions for the symptoms they endorsed. Fewer than 20% of wives who endorsed symptoms on the PTSD measure attributed these symptoms completely to their husbands' military experiences. Moreover, compared with wives who attributed symptoms only to events in their own lives, wives who attributed symptoms completely or partially to their husbands' military experiences had a greater overlap between some of their responses on the PTSD measure and their responses to a measure of general psychological distress. These results suggest that most wives of service members/veterans with PTSD experience generic psychological distress that is not conceptually consistent with STS/STSD, although a subset does appear to endorse a reaction consistent with this construct. Implications of these findings for intervention and research with this vulnerable population are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved) 相似文献

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. 相似文献

Growing evidence suggests that posttraumatic stress disorder (PTSD) is associated with poorer health status (e.g., more medical disease, physical symptoms, and sick visits to health care professionals) among veterans who served in Operation Enduring Freedom (OEF) in Afghanistan and Operation Iraqi Freedom (OIF) in Iraq. We investigated whether PTSD, depression, and substance use disorders independently predicted health status over time among OEF/OIF veterans. Information regarding psychiatric and medical conditions and health care utilization was culled for 4,463 OEF/OIF veterans enrolled in Veterans Administration primary care for a period of 6 years. Data were analyzed using multilevel modeling and generalized estimating equations. Results suggest that PTSD, depression, and substance use disorders are independently associated with increased medical disease burden and mental health care utilization but not increased medical health care utilization. The association between PTSD and medical disease burden strengthened over time. These data suggest that OEF/OIF veterans with PTSD may be at risk for increasingly poorer physical health in terms of medical disease burden over time.
