Gewalterfahrungen und psychische Gesundheit im Verlauf bei unbegleiteten minderjährigen Flüchtlingen in Deutschland

Zusammenfassung. Hintergrund: Über die seelische Gesundheit von minderjährigen Flüchtlingen, die ohne sorgeberechtigte Person nach Deutschland gereist sind, liegen bisher kaum Daten und keinerlei längsschnittliche Untersuchungen vor. Fragestellung: Ziel ist es daher, die psychische Gesundheit im Zusammenhang mit stressvollen Erfahrungen (insbesondere familiäre und organisierte Gewalterfahrungen) sowie deren Entwicklung nach etwa zwei Jahren bei unbegleiteten minderjährig Geflüchteten in Deutschland zu untersuchen. Methode: In einer Querschnittsstudie wurden belastende Erlebnisse sowie posttraumatische, depressive und psychosomatische Symptome bei 57 unbegleiteten und 22 begleiteten minderjährig eingereisten Flüchtlingen mittels strukturierter klinischer Interviews untersucht. Nach durchschnittlich 20 Monaten wurde eine Subgruppe der unbegleiteten Minderjährigen erneut untersucht. Ergebnisse: Ein Drittel der Teilnehmer erfüllte die Kriterien einer PTBS-Diagnose nach DSM-IV. Nach Einbezug einer Gruppe begleiteter minderjähriger Flüchtlinge zeigte sich, dass vor allem organisierte und familiäre Gewalterfahrungen sowie die Dauer der Flucht bedeutsame Prädiktoren hinsichtlich der PTBS-Symptomschwere waren. Für das psychische Wohlbefinden insgesamt waren die erfahrene Gewalt in der Herkunftsfamilie, bestehende Freundschaften und das Vorhandensein von Privatsphäre relevant. Ergebnisse einer Folgeuntersuchung mit einer Teilgruppe der UMF etwa 20 Monate später zeigten, dass die psychische Beeinträchtigung im Durchschnitt unverändert hoch geblieben war. Fazit: Die Möglichkeit einer frühzeitigen psychischen Untersuchung mit Erfassung kindlicher Gewalterlebnisse sowie ein verbesserter Zugang zu einer traumafokussierten Behandlung mit Sprachmittlern sind wichtig, um Leid zu reduzieren und Integration zu ermöglichen.

The neural dynamics of deficient memory control in heavily traumatized refugees

Victims of war, torture and natural catastrophes are prone to develop posttraumatic stress disorder (PTSD). These individuals experience the recurrent, involuntary intrusion of traumatic memories. What neurocognitive mechanisms are driving this memory disorder? Here we show that PTSD symptoms in heavily traumatized refugees are related to deficits in the effective control of memory retrieval. In a think/no-think task, PTSD patients were unable to forget memories that they had previously tried to suppress when compared to control participants with the same trauma history but without PTSD. Deficits in voluntary forgetting were clinically relevant since they correlated with memory intrusions in everyday life. Magnetoencephalography (MEG) recorded during suppression attempts revealed that PTSD patients were unable to downregulate signatures of sensory long-term memory traces in the gamma frequency band (70-120 Hz). Thus, our data suggest that the inability to suppress unwanted memories through modulation of gamma activity is related to PTSD symptom severity.

Psychopathological sequelae of female genital mutilation and their neuroendocrinological associations

BACKGROUND

Anecdotal evidence suggests the frequently traumatic nature of female genital mutilation (FGM). At present, systematic research on the psychological sequelae of this tradition has remained limited. The study provides preliminary, high-quality psychodiagnostic data on potential psychopathological consequences of FGM, with a focus on posttraumatic stress disorder (PTSD), shutdown dissociation and other stress-related variables.

METHODS

We investigated a convenience sample of N = 167 women, supported by the women's affairs headquarters in Jijiga (capital of the Ethiopian Somali Region) and a local Ethiopian non-governmental organization. Our main outcome measures were PTSD (PSS-I) and shutdown dissociation (ShuD). We also assessed depression and anxiety (HSCL-25), major depression, substance abuse and dependence, suicidality and psychotic disorders (M.I.N.I.; sub-scales A., B., K., and L.). In addition, we collected hair samples to assess hair cortisol concentrations (HCC) as a neuroendocrinological measure.

RESULTS

The majority of women endured FGM (FGM I: 36%, FGM II/III: 52%) and, regardless of the level of the physical invasiveness, almost all women reported having felt intense fear and/or helplessness. FGM II/III, the more invasive form, was associated with a greater vulnerability to PTSD symptoms (p < .001) and shutdown dissociation (p < .001). Symptoms of depression (p < .05) and anxiety (p < .01) were also elevated. Random forest regression with conditional inference trees revealed evidence of an alteration of the cortisol levels in relation to the age when FGM was experienced (< 1 year) and the invasiveness of the procedure.

CONCLUSION

More extensive forms of FGM are associated with more severe psychopathological symptoms - particularly with an increased vulnerability to PTSD. Higher hair cortisol levels in women who experienced FGM before their first year of age or had more severe forms of FGM indicate long-term neuroendocrinological consequences of FGM and trauma in general on the stress system.

Psychosocial Risk Factors for Child Welfare among Postpartum Mothers with a History of Childhood Maltreatment and Neglect

Background: Childhood maltreatment (CM) can increase the risk of psychosocial risk factors in adulthood (e. g. intimate partner violence, financial problems, substance abuse or medical problems). The transition to parenthood presents those affected by CM with particular challenges, in addition to usual birth-related stressors. Methods: In this cross-sectional study a total of 240 women were interviewed in the puerperium with respect to CM experiences, using the German version of the Childhood Trauma Questionnaire (CTQ). Current psychosocial risk factors (e. g. financial concerns, maternal mental illness, single parent) were assessed using the Constance Index (KINDEX) for early childhood risk factors. Associations between CM experience and psychosocial risk factors were calculated using simple correlation. Results: The average age of participants was 33 years. On the CTQ 13.8 % of participants reported emotional abuse, 6.7 % physical abuse and 12.5 % sexual abuse, while 32.1 % reported emotional neglect and 7.5 % physical neglect during childhood. With rising severity of CM, more psychosocial risk factors (KINDEX) were present. Conclusions: This study shows a clear association between experiences of maltreatment during childhood and the presence of psychosocial stressors among women in the puerperium. Regular screening for a history of CM and parental psychosocial stressors should be conducted early, i.e. during pregnancy, to avoid negative consequences for the child.

Prenatal screening for psychosocial risks in a high risk-population in Peru using the KINDEX interview

BACKGROUND

Prenatal stress and other prenatal risk factors (e.g. intimate partner violence) have a negative impact on mother's health, fetal development as well as enduring adverse effects on the neuro-cognitive, behavioral and physical health of the child. Mothers of low socio-economic status and especially those living in crime-ridden areas are even more exposed to a host of risk factors. Societies of extreme violence, poverty and inequalities, often present difficulties to provide adequate mental health care to the most needed populations. The KINDEX, a brief standardized instrument that assesses 11 different risk factors was used by midwives to identify pregnant women at-risk, in a suburban area with one of the highest levels of domestic violence in Lima. The instrument was designed to be used by medical staff to identify high-risk child-bearing women and, based on the results, to refer them to the adequate psychological or social support providers. The aim of this study is to assess the feasibility of psychosocial screening using the KINDEX in a Latin American Country for the first time, and to explore the relationship of the KINDEX with thee major risk areas, maternal psychopathology, perceived stress and traumatic experiences.

METHODS

The study was conducted in cooperation with the gynecological department of a general hospital in a suburban area of Lima. Nine midwives conducted interviews using the KINDEX of ninety-five pregnant women attending the gynecological unit of the hospital. From these, forty pregnant women were re-interviewed by a clinical psychologist using established instruments in order to assess the feasibility of the prenatal assessment in public health settings and the relationship of the KINDEX with maternal perceived stress, psychopathology symptoms and trauma load during pregnancy.

RESULTS

We found high rates of risk factors in the examined pregnant women comparable with those found in the general population. Significant correlations were found between the KINDEX sum score and the three risks areas, stress, psychopathology and trauma load as assessed in the Clinical Expert interviews. The different risks assessed by the KINDEX are related to higher levels of stress, psychopathology and trauma load, depending on the risk.

CONCLUSIONS

The relationship between past adverse experience and current stressors with perceived maternal stress, psychopathology symptoms and traumatic experiences confirm the importance of prenatal assessment for psychosocial risks. The use of KINDEX by midwives providing obstetrical care to pregnant women in urban Peru is feasible and can be used to identify high-risk women and refer them to the adequate mental health or social services for necessary attention and support. Early interventions are essential to mitigating the adverse effects of maternal stress, trauma and psychopathology on the fetus and child.

Are experiences of family and of organized violence predictors of aggression and violent behavior? A study with unaccompanied refugee minors

BACKGROUND

There is strong support for familial abuse as a risk factor for later delinquency and violent offending, whereas empirical evidence about the contribution of experienced organized violence to the cycle of violence is less clear. Nevertheless not all abused children do become violent offenders. This raises the question of which factors influence these children's risk of future aggressive behavior. Recent evidence suggests that the trait of appetitive aggression plays an important role in the prediction of aggressive behavior.

OBJECTIVE

The focus of the study is to investigate whether exposures to 1) organized; and 2) family violence equally contribute to aggressive behavior and how this is related to a trait of appetitive aggression. Furthermore it is of interest to uncover how the severity of posttraumatic stress disorder (PTSD) symptoms modulates associations between violent experiences and aggression.

METHOD

To answer these questions, we investigated unaccompanied refugee minors who had been exposed to varying levels of both violence types. Using structured interviews, experiences of organized and familial violence, self-committed aggressive acts, the trait of appetitive aggression, and PTSD symptoms were assessed in 49 volunteers.

RESULTS

A sequential regression analysis revealed that the trait of appetitive aggression and experienced family violence were independent and significant predictors of self-committed aggressive acts, altogether accounting for 70% of the variance. Exposure to organized violence, however, was not significantly associated with aggressive acts or appetitive aggression. PTSD symptom severity was not correlated with measures of aggression but with the exposure to familial and organized violence.

CONCLUSIONS

Results suggest that in addition to the impact of family violence, an elevated trait of appetitive aggression plays a crucial role in aggressive behavior and should be considered in psychotherapeutic treatment.

Effects of psychotherapy on DNA strand break accumulation originating from traumatic stress

BACKGROUND

Previous research reveals an association between traumatic stress and an increased risk for numerous diseases, including cancer. At the molecular level, stress may increase carcinogenesis via increased DNA damage and impaired DNA repair mechanisms. We assessed DNA breakage in peripheral blood mononuclear cells from individuals with post-traumatic stress disorder (PTSD) and measured the cellular capacity to repair single-strand breaks after exposure to ionizing X-radiation. We also investigated the effect of psychotherapy on both DNA breakage and DNA repair.

METHODS

In a first study we investigated DNA breakage and repair in 34 individuals with PTSD and 31 controls. Controls were subdivided into 11 trauma-exposed subjects and 20 individuals without trauma exposure. In a second study, we analysed the effect of psychotherapy (Narrative Exposure Therapy) on DNA breakage and repair. Thirty-eight individuals with PTSD were randomly assigned to either a treatment or a waitlist control condition. Follow-up was performed 4 months and 1 year after therapy.

RESULTS

In study 1 we found higher levels of basal DNA breakage in individuals with PTSD and trauma-exposed subjects than in controls, indicating that traumatic stress is associated with DNA breakage. However, single-strand break repair was unimpaired in individuals with PTSD. In study 2, we found that psychotherapy reversed not only PTSD symptoms, but also DNA strand break accumulation.

CONCLUSION

Our results show - for the first time in vivo - an association between traumatic stress and DNA breakage; they also demonstrate changes at the molecular level, i.e., the integrity of DNA, after psychotherapeutic interventions.

Adverse childhood experiences, mental health, and quality of life of Chilean girls placed in foster care: An exploratory study

In Latin America, little research has been conducted regarding exposure to adverse childhood experiences (ACEs), mental health, and health-related quality of life (HRQoL) among foster children. This study examined the association between ACEs and mental health, posttraumatic stress disorder (PTSD), and HRQoL in Chilean foster girls relative to age-matched Chilean family girls. Data were obtained from 27 Chilean foster girls and 27 Chilean girls ages 6 to 17 years living in family homes. Standardized self- and proxy-report measures were used. Foster girls reported more ACEs than controls in terms of familial and nonfamilial sexual abuse and both emotional and physical neglect. Girls living in foster care had a significantly higher rate of PTSD, displayed greater behavioral and emotional problems, and reported a lower HRQoL. Analysis confirmed the well-known cumulative risk hypothesis by demonstrating a significant positive association between the number of ACEs and PTSD symptom severity and a significant negative association with HRQoL. Chilean foster girls endured more ACEs that impair mental health and HRQoL than age-matched peers living with their families. These findings have implications for out-of-home care services in Latin America, highlighting the need to implement not only appropriate trauma-focused treatments but also appropriate prevention strategies.

From War to Classroom: PTSD and Depression in Formerly Abducted Youth in Uganda

BACKGROUND

Trained local screeners assessed the mental-health status of male and female students in Northern Ugandan schools. The study aimed to disclose potential differences in mental health-related impairment in two groups, former child soldiers (n = 354) and other war-affected youth (n = 489), as well as to separate factors predicting mental suffering in learners.

METHODS

Participants were randomly selected. We used the Post-Traumatic Diagnostic Scale to assess symptoms of post-traumatic stress disorder (PTSD) and for potential depression the respective section of the Hopkins Symptom Checklist with a locally validated cut-off.

RESULTS

Almost all respondents had been displaced at least once in their life. 30% of girls and 50% of the boys in the study reported past abduction history. Trauma exposure was notably higher in the group of abductees. In former child soldiers, a PTSD rate of 32% was remarkably higher than that for non-abductees (12%). Especially in girls rates of potential depression were double those in the group of former abductees (17%) than in the group of non-abductees (8%). In all groups, trauma exposure increased the risk of developing PTSD. A path-analytic model for developing PTSD and potential depression revealed both previous trauma exposure as well as duration of abduction to have significant influences on trauma-related mental suffering. Findings also suggest that in Northern Ugandan schools trauma spectrum disorders are common among war-affected learners.

CONCLUSIONS

Therefore, it is suggested the school context should be used to provide mental-health support structures within the education system for war-affected youth at likely risk of developing war-related mental distress.

Obstetric care providers are able to assess psychosocial risks, identify and refer high-risk pregnant women: validation of a short assessment tool - the KINDEX Greek version

Background

Prenatal assessment for psychosocial risk factors and prevention and intervention is scarce and, in most cases, nonexistent in obstetrical care. In this study we aimed to evaluate if the KINDEX, a short instrument developed in Germany, is a useful tool in the hands of non-trained medical staff, in order to identify and refer women in psychosocial risk to the adequate mental health and social services. We also examined the criterion-related concurrent validity of the tool through a validation interview carried out by an expert clinical psychologist. Our final objective was to achieve the cultural adaptation of the KINDEX Greek Version and to offer a valid tool for the psychosocial risk assessment to the obstetric care providers.

Methods

Two obstetricians and five midwives carried out 93 KINDEX interviews (duration 20 minutes) with pregnant women to assess psychosocial risk factors present during pregnancy. Afterwards they referred women who they identified having two or more psychosocial risk factors to the mental health attention unit of the hospital. During the validation procedure an expert clinical psychologist carried out diagnostic interviews with a randomized subsample of 50 pregnant women based on established diagnostic instruments for stress and psychopathology, like the PSS-14, ESI, PDS, HSCL-25.

Results

Significant correlations between the results obtained through the assessment using the KINDEX and the risk areas of stress, psychopathology and trauma load assessed in the validation interview demonstrate the criterion-related concurrent validity of the KINDEX. The referral accuracy of the medical staff is confirmed through comparisons between pregnant women who have and have not been referred to the mental health attention unit.

Conclusions

Prenatal screenings for psychosocial risks like the KINDEX are feasible in public health settings in Greece. In addition, validity was confirmed in high correlations between the KINDEX results and the results of the validation interviews. The KINDEX Greek version can be considered a valid tool, which can be used by non-trained medical staff providing obstetrical care to identify high-risk women and refer them to adequate mental health and social services. These kind of assessments are indispensable for the promotion of a healthy family environment and child development.

Obstetric care providers assessing psychosocial risk factors during pregnancy: validation of a short screening tool - the KINDEX Spanish Version

BACKGROUND

High levels of stress due to diverse psychosocial factors have a direct impact on the mothers' wellbeing during pregnancy and both direct and indirect effects on the fetus. In most cases, psychosocial risk factors present during pregnancy will not disappear after delivery and might influence the parent-child relationship, affecting the healthy development of the offspring in the long term. We introduce a short innovative prenatal assessment to detect psychosocial risk factors through an easy to use instrument for obstetrical medical staff in the daily clinical practice, the KINDEX Spanish Version.

METHODS

In the present study midwives and gynecologists interviewed one hundred nineteen pregnant women in a public health center using the KINDEX Spanish Version. Sixty-seven women were then randomly selected to participate in an extended standardized validation interview conducted by a clinical psychologist using established questionnaires to assesses current stress (ESI, PSS-14), symptoms of psychopathology (HSCL-25, PDS) and traumatic experiences (PDS, CFV). Ethical approval was granted and informed consent was required for participation in this study.

RESULTS

The KINDEX sum score, as assessed by medical staff, correlated significantly with stress, psychopathology and trauma as measured during the clinical expert interview. The KINDEX shows strong concurrent validity. Its use by medical staff in daily clinical practice is feasible for public health contexts. Certain items in the KINDEX are related to the respective scales assessing the same risks (e.g.PSS-4 as the shorter version of the PSS-14 and items from the ESI) used in the validation interview.

CONCLUSIONS

The KINDEX Spanish Version is a valid tool in the hands of medical staff to identify women with multiple psychosocial risk factors in public health settings. The KINDEX Spanish Version could serve as a base-instrument for the referral of at-risk women to appropriate psychosocial intervention. Such early interventions could prove pivotal in preventing undesirable mother-child relationships and adverse child development.

The effect of trauma-focused therapy on the altered T cell distribution in individuals with PTSD: evidence from a randomized controlled trial

Posttraumatic stress disorder (PTSD) is associated with a reduced ratio of naïve cytotoxic T lymphocytes, an increased ratio of memory cytotoxic T lymphocytes, and a reduced proportion of FoxP3(+) regulatory T lymphocytes. This study investigated whether these immunological alterations are reversible through an evidence-based psychotherapeutic treatment. Therefore, 34 individuals with PTSD were randomly assigned to either a treatment condition of 12 sessions narrative exposure therapy (NET) or a waitlist control (WLC) group. PTSD symptoms were significantly reduced in the NET group, but not in the WLC group, four months post-therapy (effect size: Hedges' g = -1.61). One year after therapy, PTSD symptoms were improved even further in the NET group compared to baseline (Hedges' g = -1.96). This symptom improvement was mirrored in an increase in the originally reduced proportion of regulatory T cells (Tregs) in the NET group at the one-year follow-up, when comparing subgroups matched for baseline Treg numbers. However, no changes were found for the initially reduced proportion of CD45RA(+)CCR7(+) naïve T lymphocytes. In conclusion, NET was effective in reducing trauma-related PTSD symptoms and had a positive effect on the proportion of Tregs cells, thus demonstrating an effect of psychotherapy on an immunological level. Yet, the shift in the proportion of naïve and memory T lymphocytes in individuals with PTSD, discussed in the literature as a correlate of premature immunosenescence, was not reversible and thus might render these patients permanently more susceptible to infectious diseases.

KERF–Ein Instrument zur umfassenden Ermittlung belastender Kindheitserfahrungen

Hintergrund: Belastende Kindheitserfahrungen steigern das Risiko für Psychopathologie und beeinflussen die Erkrankungsschwere und den Behandlungserfolg. Validierte Instrumente zur umfangreichen Erfassung von Kindheitsbelastungen sind für die klinisch-psychologische Arbeit unabdingbar jedoch nur bedingt vorhanden. Fragestellung: Diese Arbeit stellt die Konstruktion und psychometrische Prüfung der Skala „Belastende Kindheitserfahrungen” (KERF), einem Instrument zur umfangreichen Erfassung von Kindheitsbelastungen vor. Die KERF beruht auf einer modifizierten Version des US-amerikanischen „Adversive Childhood Experiences” Index. Methode: Basierend auf den Daten von 165 Probandinnen wurden mit Rasch-Modellen zehn Subskalen modelliert. Korrelationen mit dem CTQ (Childhood Trauma Questionnaire) und Psychopathologie wurden bestimmt. Ergebnisse: Unterstützt durch konzeptuelle Überlegungen konnten zehn Subskalen gebildet werden. Wir fanden zufriedenstellende Assoziationen mit dem CTQ und Psychopathologie. Schlussfolgerungen: KERF ermöglicht eine detaillierte valide Erfassung belastender Kindheitserfahrungen.

Traumatisierte Mütter – traumatisierte Kinder?

Hintergrund: Die Prävalenz von Traumafolgestörungen bei erwachsenen Flüchtlingen ist bekanntermaßen hoch. Gleichzeitig zeigen auch Flüchtlingskinder multiple psychische Auffälligkeiten und Funktionseinschränkungen. Theorien zu generationsübergreifender Traumatisierung vermuten, dass die Posttraumatische Belastungsstörung (PTBS) der Eltern sowie familiäre Gewalt die psychische Gesundheit der Kinder maßgeblich beeinflussen. Doch auch andere Faktoren wie eigene traumatische Erfahrungen im Herkunfts- und Aufnahmeland oder die Lebensbedingungen im Exil stehen möglicherweise mit der psychischen Gesundheit der Kinder in Zusammenhang. Fragestellung: Ziel der vorliegenden Arbeit ist es, den Zusammenhang von PTBS, weiteren Traumafolgeerkrankungen und Gewalterfahrungen von Flüchtlingsmüttern und ihren Kindern transgenerational zu untersuchen. Methode: 41 Flüchtlingsmütter und ihre Kinder (Alter 11-18 Jahre) wurden mit Hilfe von standardisierten, psychodiagnostischen Instrumenten unabhängig voneinander interviewt. Bei den Kindern wurde das Ausmaß der erlebten familiären Gewalt, erlebte traumatische Ereignisse, Ängstlichkeit, Depressivität sowie PTBS erfasst. Bei den Müttern wurde das Ausmaß der erlebten familiären Gewalt in der Kindheit, Gewalterfahrungen in der Partnerschaft in den letzten 12 Monaten ebenso wie andere traumatische Ereignisse sowie PTBS und Depressivität erhoben. Ergebnisse: Die Schwere der PTBS-Symptomatik bei den Müttern zeigt keinen direkten Zusammenhang mit der PTBS-Symptomatik, der Ängstlichkeit und der Depressivität der Kinder. Die Schwere der mütterlichen PTBS-Symptomatik ist aber mit der vom Kind erlebten familiären Gewalt positiv assoziiert. Die von den Kindern berichtete Anzahl unterschiedlicher traumatischer Ereignistypen und das Ausmaß der familiären Gewalt korrelieren wiederum positiv sowohl mit deren PTBS-Symptomatik als auch mit deren Depressivität und Ängstlichkeit. Schlussfolgerung: Die Ergebnisse veranschaulichen, dass nicht die PTBS-Symptomatik der Mutter, sondern die von den Kindern selbst erlebten traumatischen Erfahrungen, einschließlich der erlebten familiären Gewalt, mit den Traumafolgeerkrankungen der Kinder in Zusammenhang stehen. Die PTBS-Symptomatik der Mutter steht jedoch mit der vom Kind erlebten familiären Gewalt in Zusammenhang. Psychotherapeutische, trauma-fokussierte Interventionen sind daher sowohl für Mütter als auch Kinder indiziert. Darüber hinaus können Elterntrainings sinnvoll sein, um langfristig den Zyklus der Gewalt zu durchbrechen.

Directed forgetting in post-traumatic-stress-disorder: a study of refugee immigrants in Germany

People with post-traumatic stress disorder (PTSD) often suffer from memory disturbances. In particular, previous studies suggest that PTSD patients perform atypically on tests of directed forgetting, which may be mediated by an altered emotional appraisal of the presented material. Also, a special role of dissociative symptoms in traumatized individuals’ memory performance has been suggested. Here, we investigate these issues in traumatized immigrants in Germany. In an item-method directed forgetting task, pictures were presented individually, each followed by an instruction to either remember or forget it. Later, recognition memory was tested for all pictures, regardless of initial instruction. Overall, the PTSD group’s discrimination accuracy was lower than the control group’s, as PTSD participants produced fewer hits and more false alarms, but the groups did not differ in directed forgetting itself. Moreover, the more negatively participants evaluated the stimuli, the less they were able to discriminate old from new items. Participants with higher dissociation scores were particularly poor at recognizing to-be-forgotten items. Results confirm PTSD patients’ general discrimination deficits, but provide no evidence for a distinct directed forgetting pattern in PTSD. Furthermore, data indicate that, in general, more negatively perceived items are discriminated with less accuracy than more positively appraised ones. Results are discussed in the larger context of emotion and stress-related modulations of episodic memory, with particular focus on the role of dissociative symptoms.
