RESUMO

BACKGROUND: Interpersonal violence damages mental health and frequently leads to aggressive defence strategies. If survivors are subsequently blamed for the events, both consequences worsen. Stigma flourishes, especially when survivors are silenced so that details of the trauma remain unknown. Breaking the secrecy both at the individual and collective level is key to enable the healing and reconciliation of individuals and communities living under continuous threat. METHOD: The NETfacts health system is a stepped care model with three components: (1) Narrative Exposure Therapy (NET), an evidence-based trauma therapy that includes survivor testimony (2) NET for Forensic Offender Rehabilitation (FORNET) acknowledges that perpetrators are frequently also victims and assists in reducing aggression and the attraction to violence, and (3) a community intervention disseminating and discussing Facts derived from NET treatment (NETfacts) to challenge the collective avoidance of atrocities and other traumatic material. The intervention was piloted in a community with 497 adult residents in Eastern Democratic Republic of Congo. The willingness of clients to consent to sharing their anonymised testimonies (with a focus on sexual violence survivors and ex-combatants) was investigated, together with other components of feasibility including security and clinical safety, extent of support of respected local authorities and participation rates. As secondary outcomes, clinical and social measures were assessed before and post NETfacts among 200 village residents of whom 160 self-enrolled and 40 had not participated in any form of treatment. RESULTS: Implementation was feasible with 248 clients from a partner project giving consent to use their testimonies and high support of respected local authorities and participation rates (56% of residents self-enrolled in NETfacts). Immediate beneficial effects were shown for posttraumatic stress and rejection of rape myths among NETfacts participants who experienced multiple traumatic events in their own past. Attitudes towards ex-combatants improved and the perceived lack of social acknowledgement after trauma increased independent from participation. No significant change was observed for depressive symptoms. CONCLUSION: NETfacts is a feasible and promising approach to challenge the culture of secrecy surrounding trauma, suppression and social exclusion. Long term effectiveness requires further evaluation.

RESUMO

War and crises affect mental health, social attitudes, and cultural norms, which can exacerbate the state of long-term insecurity. With decades of armed conflict, the Democratic Republic of Congo is one example, and violence has become normalized in civilian settings. In this study, we tested the effectiveness of the NETfacts health system, an integrated model of evidence-based individual trauma treatment (Narrative Exposure Therapy [NET]) and a trauma-informed community-based intervention (NETfacts). Alongside changes in mental health outcomes (posttraumatic stress disorder, depression, social disapproval, and shame) we also investigated change in attitudes, including rape myth acceptance, stigmatization of survivors of sexual violence, and skepticism about the reintegration of former combatants. To test whether the additional community intervention is superior to individual NET alone, we implemented a randomized controlled design with six villages and interviewed a sample of 1,066 community members. Our results demonstrate that the NETfacts health system in comparison with NET alone more effectively reduced rape myth acceptance and with it ongoing victimization and perpetration. Community members of the NETfacts group also presented with less stigmatizing attitudes against survivors of sexual violence. Skepticism about the reintegration of former combatants declined in both groups. NETfacts appears to have increased motivation to engage in individual treatment. Synergizing the healing effects of individual and collective trauma exposure, the NETfacts health system appears to be an effective and scalable approach to correct degrading or ignominious norms and restore functioning and mental health in postconflict communities.

RESUMO

The aftermath of traumatization lives on in the neural and epigenetic traces creating a momentum of affliction in the psychological and social realm. Can psychotherapy reorganise these memories through changes in DNA methylation signatures? Using a randomised controlled parallel group design, we examined methylome-wide changes in saliva samples of 84 female former child soldiers from Eastern DR Congo before and six months after Narrative Exposure Therapy. Treatment predicted differentially methylated positions (DMPs) related to ALCAM, RIPOR2, AFAP1 and MOCOS. In addition, treatment associations overlapped at gene level with baseline clinical and social outcomes. Treatment related DMPs are involved in memory formation-the key agent in trauma focused treatments-and enriched for molecular pathways commonly affected by trauma related disorders. Results were partially replicated in an independent sample of 53 female former child soldiers from Northern Uganda. Our results suggest a molecular impact of psychological treatment in women with war-related childhood trauma.Trial registration: Addressing Heightened Levels of Aggression in Traumatized Offenders With Psychotherapeutic Means (ClinicalTrials.gov Identifier: NCT02992561, 14/12/2016).

RESUMO

Gender differences (GD) in mental health have come under renewed scrutiny during the COVID-19 pandemic. While rapidly emerging evidence indicates a deterioration of mental health in general, it remains unknown whether the pandemic will have an impact on GD in mental health. To this end, we investigate the association of the pandemic and its countermeasures affecting everyday life, labor, and households with changes in GD in aggression, anxiety, depression, and the somatic symptom burden. We analyze cross-sectional data from 10,979 individuals who live in Germany and who responded to the online survey "Life with Corona" between October 1, 2020 and February 28, 2021. We estimate interaction effects from generalized linear models. The analyses reveal no pre-existing GD in aggression but exposure to COVID-19 and COVID-19 countermeasures is associated with sharper increases in aggression in men than in women. GD in anxiety decreased among participants with children in the household (with men becoming more anxious). We also observe pre-existing and increasing GD with regards to the severity of depression, with women presenting a larger increase in symptoms during the hard lockdown or with increasing stringency. In contrast to anxiety, GD in depression increased among participants who lived without children (women > men), but decreased for individuals who lived with children; here, men converged to the levels of depression presented by women. Finally, GD in somatic symptoms decreased during the hard lockdown (but not with higher stringency), with men showing a sharper increase in symptoms, especially when they lived with children or alone. Taken together, the findings indicate an increase in GD in mental health as the pandemic unfolded in Germany, with rising female vulnerability to depression and increasing male aggression. The combination of these two trends further suggests a worrying mental health situation for singles and families. Our results have important policy implications for the German health system and public health policy. This public health challenge requires addressing the rising burden of pandemic-related mental health challenges and the distribution of this burden between women and men, within families and for individuals who live alone.

RESUMO

OBJECTIVE: Individuals who return from armed groups present with a history of traumatic events including perpetration. Subsequent severe mental stress and heightened levels of reactive and appetitive aggression may persist and if left untreated, frequently impede peacebuilding and societal stability. In this study, we tested a revised adaptation of Narrative Exposure Therapy (NET; Schauer et al., 2011) for Forensic Offender Rehabilitation (FORNET) implemented in a sample of male former combatants in war-torn regions of the DR Congo. METHOD: We applied a longitudinal parallel-group randomized controlled design with treatment as usual (TAU) as control condition and 3-5 and 6-9 months follow-up assessments. The effect of treatment over time on clinical and social outcomes was tested with GLMMs; appetitive aggression and current violent behavior (CVB) were specified as primary and posttraumatic stress as secondary outcomes. RESULTS: FORNET decreased appetitive aggression (within group Cohen's dz = 2.00), CVB (dz = .90) and posttraumatic stress (dz = 1.48) significantly more than treatment as usual. Clinical significance was obtained for all outcomes. Remarkably, NET clients also reduced their substance abuse (dz = .68) even though this was not targeted within the intervention. Depression, perceived social acknowledgement and subjective solidarity with (para)military life decreased. CONCLUSION: FORNET is a compact and scalable psychotherapeutic intervention that effectively reduces current aggressive behavior including physical abuse against children, intimate partner violence (IPV), and community violence. FORNET further decreases appetitive aggression, posttraumatic stress symptoms, and other clinical and social problems that commonly hinder demobilization, reintegration, and post-conflict peacebuilding.

RESUMO

BACKGROUND: One in three individuals who live in Rio de Janeiro experience a traumatic event within a period of 12 months. In the favelas particularly, trauma exposure is ongoing. Psychological sequalae include posttraumatic stress disorder (PTSD), depression and other mental disorders. Trauma-focused therapy approaches have emerged as the treatment of choice when the dangerous events are over, but symptoms have remained for an extended time period. Ideally, the victim is in a safe context during treatment. However, frequently, survivors cannot escape from situations characterised by ongoing threat and traumatic stress. The aim of this study is to research the effectiveness of Narrative Exposure Therapy in a sample of PTSD patients living under these conditions. METHODS: Individuals fulfilling the criteria for PTSD and who live in conditions of ongoing community violence (i.e. in the favelas) in Rio de Janeiro will be randomly assigned to one of two treatments: Narrative Exposure Therapy (NET) or treatment as usual (TAU). Clinical endpoints will be primarily PTSD and secondarily symptoms of shutdown dissociation, depression, substance involvement  and functionality. DISCUSSION: Effective treatment for PTSD patients who live in unsafe conditions could substantially reduce suffering of individuals and their families in Brazil. Based on this result, the extent to which such interventions may be useful as a first step in tackling the consequences of violence on a global scale will be discussed.

RESUMO

OBJECTIVE: Former combatants are exposed to multiple traumatic stressors during conflict situations and usually participate in perpetration of violence. Ongoing perpetration of violence in post conflict areas, linked to mental health problems and appetitive aggression, destabilises peace keeping efforts. The aim of this study is to investigate lifetime exposure to violence and the relationship between this exposure and mental health and current violent behaviour in a sample of female former child soldiers with a history of perpetration of violence in Eastern DR Congo. METHODS: 98 female former child soldiers who had been abducted and forcibly recruited during the M23 insurgency (2012-2014) were assessed for lifetime exposure to trauma including perpetration of violence, clinical outcomes (PTSD and appetitive aggression), and current violent behaviour. RESULTS: Female former child soldiers had been exposed to extremely high levels of trauma including perpetration of violence and presented with high levels of mental health problems. Linear regression models showed that current violent behaviour was predicted by both PTSD and appetitive aggression. CONCLUSIONS: Trauma exposure predicts ongoing perpetration of violence post conflict via the resulting mental health problems. The findings imply that if PTSD and appetitive aggression symptoms are successfully treated, ongoing violent behaviour in the community post conflict will also decrease.

RESUMO

OBJECTIVE: Women and girls make up a sizeable proportion of armed groups in conflict regions. However, compared to males, research into the mental health of female combatants is limited and there have been no investigations into treatments. Psychological sequalae amongst predominantly male former combatants most prominently include PTSD and appetitive aggression indicating a need for trauma-focused therapy that also addresses violent behaviour with additional components that strengthen social behaviour and inclusion. The aim of this study is to research the effectiveness of a revised adaptation of Narrative Exposure Therapy in a sample of female former child soldiers. METHODS: 92 female former child soldiers who had been forcibly recruited during the M23 insurgency (2012-2014) in Eastern DRC who were found to have PTSD were randomised into groups receiving a version of Narrative Exposure Therapy adapted for offenders (FORNET) or treatment as usual. Clinical outcomes for PTSD, appetitive aggression and depression were assessed, as well as social outcomes (current violent behaviour, guilt and perceived social acknowledgement). RESULTS: High levels of trauma, historical perpetration of extreme violence and ongoing violent behaviour were found within this group. The intervention was found to be superior to treatment as usual at 3-4 month and 9 month follow up for all clinical and social endpoints. Moderate to large effect sizes were found for PTSD, aggression and depression. CONCLUSIONS: This study investigates the effectiveness of psychotherapy for former female child soldiers, and includes long term follow up. It demonstrates that FORNET combined with group therapy can effectively reduce mental health problems as well as ongoing acts of violence in female former child soldiers within post conflict communities.

RESUMO

The shift from outcrossing to selfing is often accompanied by striking changes in floral morphology towards a "selfing syndrome", which is characterized by flowers with reduction in size, pollen: ovule (P/O) ratio, and herkogamy. This study aims to test whether such changes have occurred in the North American Arabidopsis lyrata, which is of particular interest because of the relatively recent transitions to selfing in this system. Flower size, flower shape, herkogamy levels, P/O ratio, and floral integration of six self-incompatible (outcrossing) and six self-compatible (selfing) populations of A. lyrata were measured in a common environment using conventional and geometric morphometrics methods. Although selfers had on average 9.2% smaller corollas, 8.4% longer pistils, and 21.5% lower P/O ratios than outcrossers, there were no differences in shape, floral integration, and herkogamy between outcrossing and selfing populations. Moreover, most variation in floral traits was explained by population genetic background rather than by mating system. We conclude that selfing populations in A. lyrata have not evolved a selfing syndrome.

RESUMO

INTRODUCTION: The transition from cross-fertilisation (outcrossing) to self-fertilisation (selfing) frequently coincides with changes towards a floral morphology that optimises self-pollination, the selfing syndrome. Population genetic studies have reported the existence of both outcrossing and selfing populations in Arabis alpina (Brassicaceae), which is an emerging model species for studying the molecular basis of perenniality and local adaptation. It is unknown whether its selfing populations have evolved a selfing syndrome. METHODS: Using macro-photography, microscopy and automated cell counting, we compared floral syndromes (size, herkogamy, pollen and ovule numbers) between three outcrossing populations from the Apuan Alps and three selfing populations from the Western and Central Alps (Maritime Alps and Dolomites). In addition, we genotyped the plants for 12 microsatellite loci to confirm previous measures of diversity and inbreeding coefficients based on allozymes, and performed Bayesian clustering. RESULTS AND DISCUSSION: Plants from the three selfing populations had markedly smaller flowers, less herkogamy and lower pollen production than plants from the three outcrossing populations, whereas pistil length and ovule number have remained constant. Compared to allozymes, microsatellite variation was higher, but revealed similar patterns of low diversity and high Fis in selfing populations. Bayesian clustering revealed two clusters. The first cluster contained the three outcrossing populations from the Apuan Alps, the second contained the three selfing populations from the Maritime Alps and Dolomites. CONCLUSION: We conclude that in comparison to three outcrossing populations, three populations with high selfing rates are characterised by a flower morphology that is closer to the selfing syndrome. The presence of outcrossing and selfing floral syndromes within a single species will facilitate unravelling the genetic basis of the selfing syndrome, and addressing which selective forces drive its evolution.
