ABSTRACT

This study examined evidence for a dissociative subtype of post-traumatic stress disorder (PTSD) among women seeking psychotherapy for childhood sexual abuse (CSA). One hundred and twenty-two women seeking treatment for CSA completed a battery of questionnaires assessing PTSD, dissociative symptoms, and child maltreatment. Using signal detection analysis, we identified high and low dissociation PTSD subgroups. A constellation of three PTSD symptoms-hypervigilance, sense of foreshortened future, and sleep difficulties–discriminated between these two subgroups (OR = 8.15). Further evidence was provided by the finding of a nonlinear relationship between severity of childhood maltreatment and dissociation in the women with PTSD. These results provide support for a dissociative subtype of PTSD that may stem from more severe childhood experiences of neglect and abuse.  相似文献

Little attention has been given to the occurrence of dissociative symptoms during sexual behavior in adults who have experienced childhood sexual abuse (CSA). For this study, 57 adults living with HIV infection who had experienced CSA and were entering a treatment study for traumatic stress completed study assessments and clinical interviews, including a 15-item scale of dissociative experiences during sexual behavior. Predictor variables included Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision diagnoses of posttraumatic stress disorder (PTSD) and dissociative disorders, rape by an intimate partner, duration of CSA, number of perpetrators of CSA, and current sexual satisfaction. A multiple regression analysis was conducted to identify significant associations between predictors and dissociation during sex. Mean differences by clinical diagnosis were also examined. Results indicated that PTSD, dissociative disorders, rape by an intimate partner, duration of CSA, and number of perpetrators of CSA were associated with increased dissociation during sexual behavior. Dissociation during sex likely increases vulnerability to sexual revictimization and risky sexual behavior. Standard behavioral prevention interventions may be ineffective for sexual situations when dissociation occurs, and prevention efforts should be integrated with mental health care for those who have experienced CSA.  相似文献

This study examined the relationships among dissociation, childhood trauma and sexual abuse, and posttraumatic stress disorder (PTSD) symptoms in HIV-positive men. Data were collected from 167 men enrolled in a randomized clinical trial that examined a group therapy intervention to decrease HIV-related risk behavior and trauma-related stress symptoms. Participants completed the Trauma History Questionnaire, the Impact of Events Scale-Revised, and the Stanford Acute Stress Reaction Questionnaire. Overall, 35.3% of the participants reported having experienced childhood sexual abuse. A total of 55.7% of the sample met diagnostic criteria for PTSD. The intensity of dissociative symptoms that participants endorsed was positively associated with experience of childhood sexual abuse (r?=?.20, p < .01). Dissociative symptoms were also positively associated with specific PTSD symptoms, notably hyperarousal (r?=?.69, p < .001). Hierarchical regression indicated that hyperarousal symptoms accounted for more of the variance in dissociation than childhood sexual abuse. These results suggest that childhood sexual abuse may be involved in the development of dissociative symptoms in the context of adulthood stress reactions. Furthermore, the pattern of the association between dissociation and PTSD is consistent with the possibility of a dissociative PTSD subtype among HIV-positive men.  相似文献

ABSTRACT

The current study investigated the contributive role of perinatal dissociative and perinatal emotional responses to the development of PTSD symptoms following childbirth. Method: Using a prospective, longitudinal design, 140 women were studied who were followed from the first week after delivery to three months postpartum. Results: Three women (2.1%) met criteria for PTSD and 21.4% reported a traumatic childbirth experience. Both perinatal negative emotional reactions and perinatal dissociative reactions were the predictors of PTSD symptoms at three months postpartum. The effect of perinatal dissociation, however, was partially mediated by perinatal emotional reactions. Conclusion: Posttraumatic stress disorder can be a consequence of the experience of childbirth. Women who reported high levels of negative emotions during and shortly after childbirth were more likely to develop PTSD symptoms than women who did not. Women who experienced an instrumental delivery and also reported higher levels of psychoform perinatal dissociation, were at higher risk than women who reported higher levels of perinatal dissociation during a spontaneous delivery. These findings add to the growing body of literature regarding traumatic childbirth and indicate that perinatal dissociative and emotional phenomena are associated with posttraumatic stress.  相似文献

Trauma survivors with posttraumatic stress disorder (PTSD) have been shown to have lower basal cortisol levels in the urine, plasma, and saliva than in trauma survivors without PTSD, nontraumatized mentally ill, or healthy subjects. We report on a case study in which we measured pre- and post-Eye Movement Desensitization and Reprocessing (EMDR) treatment salivary cortisol levels and salivary cortisol response to 0.50 mg of dexamethasone in a 41-year-old female with chronic PTSD symptoms. Our goal was to determine whether symptom improvement following trauma-focused treatment (EMDR) is associated with changes in basal salivary cortisol or in the cortisol response to dexamethasone administration. Our findings show moderate symptom improvement, an increase in basal cortisol levels, and a more attenuated cortisol hypersuppression in response to the dexamethasone suppression test following EMDR treatment. These results suggest the potential utility of including neuroendocrine measures in the assessment of treatment outcome in PTSD.  相似文献

Abstract

Objective: Overwhelming experience can evoke psychological dissociation during or immediately after the event, including dissociative amnesia. Whereas some data suggest that such peritraumatic dissociation can also find expression in somatoform symptoms, only a limited range of such symptoms has been systematically studied. The present study hypothesized that peritraumatic psychological and somatoform dissociation are associated with each other, with delayed recall of childhood sexual abuse (CSA), and with CSA severity. Because current somatoform dissociation is most strongly associated with recalled childhood physical abuse (CPA), we also hypothesized that peritraumatic somatoform dissociation is associated with reported CPA over and above CSA.

Method: Thirty-four Dutch women who reported CSA were interviewed using a modified version of the Traumatic Memory Inventory (TMI) which assesses the characteristics of traumatic memories. The participants also completed the Traumatic Experiences Checklist, the Peritraumatic Dissociation Experiences Questionnaire, and the Peritraumatic Somatoform Dissociation Questionnaire.

Results: Peritraumatic psychological and somatoform dissociation were associated with each other, with delayed recall of trauma, and with severity of reported CS A. Reported CPA predicted peritraumatic somatoform dissociation over and above the severity of CS A in terms of the acts involved. Approximately 44% of the women reported independent corroboration of the abuse. Similar proportions of delayed, partial, and continuous CSA memories were corroborated.

Conclusions: This retrospective study suggested that delayed recall of CSA is associated with peritraumatic dissociation and CSA severity. It also suggested that trauma-especially that which involves serious threat to the integrity of the body-may evoke somatoform dissociation. Based on patient report, delayed recall of some CSA memories was as accurate as continuous recall of CSA.  相似文献

Objective: Child sexual abuse (CSA) is associated with a host of deleterious impacts, yet little is known about the short-term correlates in children. This study aimed to investigate the association between dissociation and sleep problems in a sample of preschool-age sexual abuse victims while controlling for potentially confounding variables, including gender, age, polytrauma, CSA characteristics, and parental distress. Method: The sample consisted of 179 children (ages 3–6 years) and their non-offending parents. Parents completed questionnaires assessing their child’s dissociative symptoms and sleep problems as well as their own level of psychological distress. Results: Regression analyses revealed that sleep problems were significantly associated with dissociative symptoms over and above all other control variables (children’s gender and age, polytrauma, and parental distress). A longer duration of sexual abuse also predicted greater dissociative symptoms in preschool children. Conclusion: Findings highlight the association between sleep problems and dissociation in preschool-age victims of CSA. Further research is needed to understand their impact on children’s development to design appropriate treatment and prevention initiatives aimed at fostering resilience in young vulnerable children.  相似文献

Abstract

Objective: This study tested the hypothesis that participation in war-zone atrocities would be significantly related to long-standing dissociative symptomatology among Vietnam veterans with combat-related PTSD.

Method: Self-report data concerning childhood sexual/physical abuse, combat exposure, participation in war-zone atrocities, and trait dissociation were examined.

Conclusion: Vietnam veterans who participated in war-zone atrocities are more likely to report long-standing dissociative symptoms.

Results: Exposure to childhood abuse, as well as exposure to general combat events, was not correlated with trait dissociation. However, participation in war-zone atrocities was correlated with trait dissociation.  相似文献

ABSTRACT

Data are presented on childhood maltreatment characteristics, psychological dissociation, somatoform dissociation, and offense types with a sample of 93 Canadian inmates (62 males and 31 females), with a mean age of 34 years (SD = 9.5). The present study includes findings based on the Child Maltreatment Interview Schedule-Short Form (CMIS-SF), the Detailed Assessment of Posttraumatic States (DAPS), the Multidimensional Dissociation Inventory (MDI), the Somatoform Dissociation Questionnaire (SDQ-20), and indices of violent and sexual offending during adulthood. Chi-square, Cohen's d, and regression analyses were conducted with the data. Results showed that women reported more childhood sexual abuse (CSA) than men, and men committed more violent and sexual offenses than women. Mean comparisons using Cohen's d statistic showed that inmates (N = 62) reported more trauma-related dissociation (DAPS) and more MDI dissociation compared to normative data for these instruments; however, inmates had lower somatoform dissociation scores when compared to published means of dissociative disorder, somatoform disorder, and eating-disorder patients. Inmates with CSA histories had higher SDQ-20 scores than those who did not. No differences were found between sex offenders and non-sex offenders in terms of probable PTSD, probable DID, MDI scales, or the SDQ-20. CSA that involved penetration predicted MDI dissociation and also predicted later sexual offending. Of the MDI scales, derealization and memory disturbance predicted sexual offending. Neither MDI scales nor any of the CMIS-SF maltreatment types predicted violent offending. Results are discussed in terms of treatment implications for incarcerated individuals with histories of child maltreatment.  相似文献

ABSTRACT

The dissociative subtype of posttraumatic stress disorder (PTSD) is estimated to characterize about 12-30% of those with PTSD. Some research links this subtype with increased severity of PTSD symptoms compared to samples with “classic” PTSD. However, prevalence and severity rates reported in the literature have varied. One possible explanation for these discrepancies could be related to where the populations were sampled. Therefore, we investigated whether these differences are still observed when holding level of care constant. We collected data from 104 women at a partial and residential psychiatric hospital program focused on trauma-related disorders. Participants completed self-report questionnaires assessing trauma exposure, symptoms and provisional diagnosis of PTSD, trauma-related thoughts and beliefs, and feelings of shame. All participants reported a history of childhood and/or adulthood trauma exposure. Eighty-eight (85%) met criteria for PTSD, and of those, seventy-three (83%) met criteria for the dissociative subtype as assessed by the Dissociative Subtype of PTSD Scale. A series of independent t-tests revealed no significant differences between the “classic” and dissociative PTSD groups with respect to lifetime or childhood trauma exposure, posttraumatic cognitions, shame, or overall PTSD severity. Our results suggest that samples with classic PTSD and the dissociative subtype may not differ in some types of symptom severity when holding level of care constant. Importantly, however, we found at partial/residential level of care the majority of patients with PTSD were dissociative. Given the elevated prevalence rate in this sample, these findings support the need to assess dissociative symptoms, particularly in more acute psychiatric settings.  相似文献

ABSTRACT

The present study compared (1) college students who reported childhood physical and psychological abuse (combined; N = 35) with (2) students who reported psychological abuse alone (psychological; N = 30), and with (3) students who reported no history of childhood abuse (no abuse; N = 35). Combined abuse and psychological abuse participants were more likely to receive an Axis I diagnosis on a structured interview and to report more dissociative experiences than were no abuse participants. In addition, a structured interview for dissociative disorders was the single measure that differentiated psychologically abused participants from participants reporting combined abuse and no abuse. However, the most psychological impairment was evident in the combined abuse group. Relative to participants who reported no abuse history, combined abuse participants reported more dissociative symptoms on a structured interview and more symptoms of general psycho-pathology, depression, and state and trait anger on self-report measures.  相似文献

Women's history of sexual abuse, their sexuality, and sexual self-schemas   总被引:2,自引:0,他引:2  
In this study, the authors assessed 48 female survivors of child sexual abuse (CSA) and 71 female control participants using measures of adult sexual function, psychological function (i.e., depression and anxiety), and sexual self-schemas. The primary purpose of this study was to examine whether differences existed between women with and without a history of CSA in the way that they viewed themselves as a sexual person and, if so, whether such differences mediated the link between early unwanted sexual experiences and later adult sexuality. CSA survivors were found to view themselves as less romantic and passionate than women who were not abused. In particular, CSA survivors showed an inverse relationship between romantic/passionate sexual self-schemas and negative sexual affect during sexual arousal. The relationship between CSA and negative sexual affect was independent from symptoms of depression and anxiety, suggesting that the impact of CSA on sexual self-schemas may be independent from the impact that the abuse may have in other areas of the survivor's life.  相似文献

ABSTRACT

This study investigated the frequency of self-reported childhood abuse experiences of psychiatric inpatients, and the presence of dissociative and depressive symptoms. A total of 100 Puerto Rican in-patients who were hospitalized during a two month period were included in the study. The participants' dissociative and depressive symptoms were assessed using the Dissociative Experiences Scale and a subset of its items (DES-Taxon), the Questionnaire of Experiences in Dissociation and the Beck Depression Inventory. We also used a self-report instrument to assess the frequency and severity of a variety of abusive experiences. Seventy-eight percent (78%) of the participants reported some type of abusive experiences, 38% reported extreme and frequent abuse, and 40% reported being sexually abused during childhood. The findings showed a correlation between greater frequency of the abusive experiences and higher levels of dissociative and depressive symptoms. When the variable of child sexual abuse was used, only the Dissociative Experiences Scale was able to detect differences between those patients who reported such abusive experiences and those who reported none. We conclude that the level of abusive experiences reported by psychiatric in-patients in Puerto Rico is very similar to the rate in other investigations in the international literature. The data demonstrate that the participants who report frequent and intense abuse endorse a wide variety of dissociative experiences, and, to a lesser extent, depressive symptoms. As more than 95% of our inpatients had never been screened or assessed for the possibility of a dissociative disorder, we suggest that clinicians in psychiatric units in Latin America should be more sensitive and attentive to the presence of such disorders.  相似文献

ABSTRACT

This study was designed to determine the relationship between self-reports of peritraumatic dissociation during a motor vehicle accident and measures of physiological arousal in the immediate aftermath of the accident. Upon admittance to the hospital, 15-hour urine samples were collected from participants to measure levels of urinary catecholamines and cortisol. Within two days of the accident, participants reported symptoms of peritraumatic dissociation, and one month after the accident, 59 (34 male and 25 female) participants completed an interview designed to assess symptoms of PTSD. Results revealed that patients who subsequently developed PTSD reported significantly higher levels of peritraumatic dissociation than victims who did not develop PTSD, and that dissociation was negatively associated with levels of urinary norepinephrine and epinephrine. Dissociation was not related to urinary cortisol or cardiovascular levels upon admission. These findings are consistent with previous research that has suggested that high dis-sociators may constitute a subgroup of trauma victims who are physiologically less reactive to trauma.  相似文献

One-hundred and ninety-two incarcerated women who were participating in a trauma and abuse psychoeducation program were evaluated for childhood abuse, maltreatment and current dissociative symptoms. The link between childhood abuse and adult criminal behavior has been well studied but the mental health status of adult female inmates and the possible implications for their treatment and behavior is the next step. The participants reported high levels of childhood abuse, 68% reported molestation, 72% rape, 26% emotional abuse, 51% physical abuse. Almost half of the participants reported a clinically significant level of dissociative symptoms. The dissociative group was found to have higher rates of sexual, emotional and physical abuse. They were younger and had shorter sentences. A logistic regression model was developed with only physical abuse being a predictor of clinically significant dissociative symptoms. Results are discussed in terms of how the high level of dissociative symptoms may impact future delinquency and corrections staff and possible future research.  相似文献

Biomarker composites (BCs) that objectively quantify psychosocial stress independent of self report could help to identify those at greatest risk for negative health outcomes and elucidate mechanisms of stress-related processes. Here, BCs are examined in the context of existing disease progression among HIV-positive African American men who have sex with men and women (MSMW) with high stress histories, including childhood sexual abuse. Participants (N = 99) collected 12-h overnight and morning urine samples for assay of cortisol and catecholamines (primary BC) and neopterin (an indicator of HIV disease progression). Data on cumulative psychosocial trauma history (severity, types, frequency, age at first incident), posttraumatic stress disorder (PTSD) symptoms, sexual risk behaviors, and a secondary BC consisting of routine health indicators (heart rate, blood pressure, body mass index, waist-to-hip ratio) were also collected. Lifetime trauma exposure was highly pervasive and significantly greater among those meeting a standard cutoff for PTSD caseness (24 %). After controlling for HIV factors (neopterin levels and years with disease), PTSD was a significant (p < .05) predictor of the primary, but not secondary BC. Those with PTSD also had significantly more sexual partners, sex without a condom, and exchange sex for money or drugs than those without PTSD. Specific trauma characteristics predicted PTSD severity and caseness independently and uniquely in regression models (p’s < .05–.001). A primary BC appears sensitive to cumulative trauma burden and PTSD in HIV-positive African American MSMW, providing support for the use of BCs to quantify psychosocial stress and inform novel methods for examining mechanisms of stress influenced health behaviors and disease outcomes in at-risk populations.  相似文献

BACKGROUND: Intimate partner violence (IPV) is prevalent in most parts of the world. It is also prevalent during pregnancy. METHODS: This study assessed the prevalence of IPV during pregnancy and evaluated its relationship with mental health outcomes, including depression and post-traumatic stress disorder (PTSD). Pregnant women (n=203) attending an antenatal clinic in a public hospital in Bangalore were assessed for presence of IPV as well as depressive, somatic, PTSD symptoms and life satisfaction. RESULTS: Self-reported physical violence in the last year was reported by 14% of women, psychological abuse by 15%, and sexual coercion by 9%. One-half of these women reported ongoing abuse during pregnancy. Depression, somatic, and PTSD symptoms were higher in those with a history of abuse or sexual coercion, and life satisfaction was poorer in those with any form of violence. Among those reporting a history of sexual coercion, severity of violence was related to increased psychiatric morbidity. Alcohol abuse in the spouse was a predictor of the presence and severity of abuse. LIMITATIONS: The study was conducted in a single clinic in southern India which is a large country with very diversified populations. CONCLUSION: The experience of intimate partner violence and its mental health consequences are quite prevalent in India which is a culture where gender disparities are normative and pregnancy is a particularly vulnerable period.  相似文献

BACKGROUND: Child sexual abuse (CSA) is associated, after controlling for other adversities, with a range of non-psychotic disorders in adult life. There is a need to clarify whether CSA contributes to risk of disorder in the absence of such adversities, and given that associations may be accounted for by genetic mechanisms, whether they are seen where the perpetrator of CSA is not a biological relative, and where there has been only one incident. METHODS: A questionnaire-based study of a socio-economically representative sample of women age 25-36 (N = 862) was carried out. Parental care and control were assessed using the Parental Bonding Instrument, and CSA using a previously validated questionnaire. Current affective symptoms were assessed from the depression scale of the GHQ-28. RESULTS: Low maternal and paternal care were associated with risk of abuse by a biologically unrelated perpetrator before the age of 11, but not during early adolescence. Low maternal care and CSA each made independent contributions to the prediction of affective symptoms. CSA by a non-relative was strongly associated with GHQ depression, as was CSA by a non-relative that had occurred only once. CONCLUSIONS: Quality of parental care probably influences risk of CSA by unrelated abusers in younger children, while there may be a combination of genetic and parental influences on the risk of abuse by a relative. The strong association of affective symptoms in adult life with CSA by a non-relative suggests an environmental effect. Studies, utilizing genetic designs, of the role of childhood trauma in relation to adult affective symptoms are needed.  相似文献

ABSTRACT

Research has yielded contradictory results on the relationship between childhood sexual abuse and later parental functioning. This study was undertaken to specify the link between childhood sexual abuse and maternal parenting, while taking into account mothers' childhood physical and emotional traumas and current depressive and dissociative symptoms. Data were collected through self-report measures completed by 93 French-speaking Canadian mothers of children aged 6 to 11 years referred to Youth Protection Services. Parental behaviors examined included involvement with the child, use of positive reinforcement, lack of monitoring and supervision of the child, inconsistency in applying discipline, and use of corporal punishment. Mothers' perception of the quality of the relationship with her child was also assessed. In addition, history of abuse and neglect, depression and dissociation were respectively measured with the Childhood Trauma Questionnaire, the Diagnostic Interview Schedule Simplified, and the Dissociative Experiences Scale. The short-form of the Marlowe-Crowne Social Desirability Scale was used to control for respondent bias aimed at minimizing their problems. Mothers' current depressive symptoms were not found to predict any of the parental dimensions measured. Results from multiple hierarchical regressions pointed to dissociative symptoms as the key predictor of parental practices and attitudes. More specifically, dissociative symptoms predicted the use of positive reinforcement, lack of monitoring and supervision of the child, inconsistency in applying discipline, and use of corporal punishment. Dissociation also mediated the association between childhood maltreatment (physical and emotional abuse and neglect) and inconsistency in applying discipline. Implications for research and practice are discussed.  相似文献

Childhood sexual abuse (CSA) is associated with post-traumatic stress disorder (PTSD), which can be associated with condomless sex among men who have sex with men (MSM). However, the impact of moderating factors on the relationship between PTSD symptom severity and condomless sex is poorly understood. We examined whether PTSD symptom severity was associated with condomless sex among MSM with CSA histories, and whether substance dependence, self-esteem, and distress tolerance moderated that relationship (n = 288). Notably, no direct relationship between PTSD symptom severity and condomless sex was found. Adjusted models indicated that condomless sex was differentially impacted by PTSD symptom severity among those without substance dependence (ΔR2 = 0.03, p = 0.034) and, counterintuitively, those with high self-esteem (ΔR2 = 0.07, p = 0.005). PTSD symptom severity was associated with condomless sex across levels of distress tolerance. Findings indicate that substance use, self-esteem, and distress tolerance should be targeted in high-risk MSM with CSA even if they do not have PTSD.  相似文献
