RESUMO

BACKGROUND: Post-traumatic stress but also aggressive attitudes and behaviour can be found in adolescents living in a context of ongoing community and gang violence in the low-income urban areas of Cape Town, South Africa. AIMS: We investigated the long-term effects (15-20 months after therapy) of (a) Narrative Exposure Therapy for Forensic Offender Rehabilitation (FORNET) and (b) the cognitive behavioural intervention 'Thinking for a Change' (CBT) on post-traumatic stress disorder (PTSD) and aggression compared with a waiting list. METHOD: Fifty-four young males participated in the treatment trial, of which 17 completed the FORNET intervention, 11 the CBT intervention, and 26 were on a waiting list. The primary outcome was the change score for the Appetitive Aggression Scale; secondary outcomes were the PTSD Symptom Scale-Interview change scores, and the number of perpetrated violent event types. RESULTS: The reduction in scores for PTSD that had been observed in FORNET completers at the first follow-up were still significant at the second long-term follow-up (Cohen's d = 0.86). In this treatment arm (FORNET), the scores for appetitive aggression were also significantly reduced (Cohen's d = 1.00). There were no significant changes observed for CBT or for the waiting list. CONCLUSIONS: The study indicates that FORNET can successfully reduce post-traumatic stress as well as the attraction to violence even for individuals living under conditions of continuous traumatic stress.

RESUMO

OBJECTIVES: People with multiple sclerosis (pwMS) often have magnetic resonance imaging (MRI) examinations. While MRI can help guide MS management, it may be a source of anxiety for pwMS. We aimed to develop and validate a questionnaire on the "EMotions and Attitudes towards MRI" (MRI-EMA). MATERIAL AND METHODS: The questionnaire was developed, tested in two samples of pwMS and validated in a sample of n = 457 pwMS using exploratory (EFA) and confirmatory factor analysis (CFA). RESULTS: EFA revealed four factors underlying the questionnaire: fear of MRI scan, fear of MRI results, feeling of control over the disease and feeling of competence in the patient-physician encounter. CFA confirmed the model fit. Receiving the MRI results, but not undergoing the procedure was associated with anxiety. Seeing MRI results gave participants a feeling of control over the disease. Only 50% felt competent to discuss MRI findings with their physician. Fear of MRI results was especially high and feeling of competence low in participants with a short disease duration and little MRI experience. CONCLUSION: PwMS do not feel competent when discussing the role, MRI plays in their care. Receiving MRI results caused anxiety and provides some pwMS with a-perhaps false-feeling of control over the disease. The MRI-EMA constitutes a new tool for the assessments of pwMS' feelings towards MRI, that can be applied in future research and clinical settings.

RESUMO

OBJECTIVE: Quality of life (QoL) is a crucial goal of post-transplant care. This study investigated predictors of QoL within the first 6 months after transplantation. METHODS: Forty patients were assessed 2 weeks (T1), 3 months (T2), and 6 months post-transplant (T3). In the quantitative part, the EuroQol questionnaire (EQ-5D) and visualization methods (Prism) were applied. In the qualitative part, interviews were analyzed. Regression analyses were used to investigate the impact of the pictorial ratings at T1 on QoL at T2 and T3. The pictorial variables were related to the interviews for an in-depth analysis. RESULTS: There was an increase in QoL between T1 and T2 that remained stable from T2 to T3. Smaller distances in the variable Prism_Lung (acceptance of the lung) and larger distances in the variable Prism_Transplantation (distance to the transplantation experience) were related to the increase in QoL between T1 and T2 and to an higher QoL at T2. High-QoL patients were able to create an equilibrium of defense and acceptance. CONCLUSION: Psychological processes early after transplant are of significance for the development of QoL within the 6 months following the surgery. These insights demonstrate that a mixed methodological approach provides a helpful understanding of post-transplant processing.

RESUMO

Various scientific disciplines devoted to the study of sexual behavior are concerned with the understanding of sadomasochistic (SM) practices. However, only a fragmented body of theories, opinions, and studies is available, which limits the systematic study of this field. Empirical studies and tools for the assessment of SM tendencies are particularly sparse. Our aim was to develop a comprehensive tool for the assessment of an individual's engagement in SM practices. A comprehensive 24-item checklist of different types of SM play was generated with the assistance of members of the German SM community, covering both a dominance scale and a submission scale. The sadomasochism checklist was administered in an online study to a sample of 652 adults (345 female, 307 male), with 527 participants being active members in the SM community. Both the frequency of SM behavior and the attraction to the types of SM practices were assessed. Results revealed a one-factor structure for the dominance as well as the submission scale. The distinction between different types of practices (soft play, domination/submission, beating, toys, breath and bodily fluids) was confirmed using principal component analysis. Cronbach's alpha was appropriate. The total scores for the dominance and the submission scale distinguish between participants with different preferences for dominant and submissive practices. The newly developed scale is a reliable and valid tool for the assessment of the frequency of and attraction to SM behavior. It aims to provide the basis for future systematic studies on sadomasochism.

RESUMO

BACKGROUND: Psychosocial stress caused by war, ongoing conflict, lack of security, and restricted access to resources promotes mental suffering and diseases in many resource-poor countries. In an exemplary setting, the present study compares the efficacy of psychosocial counselling with routine pharmacological treatment in a randomised trial in Mazar-e-Sharif (Afghanistan). METHODS: Help seeking Afghan women (N = 61), who were diagnosed with mental health symptoms by local physicians either received routine medical treatment(treatment as usual) or psychosocial counselling (5-8 sessions) following a specifically developed manualised treatment protocol. Primary outcome measures were symptoms of depression and anxiety assessed before treatment and at follow-up using the Hopkins Symptom Checklist and the Mini-International Neuropsychiatric Interview. Secondary outcome measures were psychosocial stressors and coping mechanisms. RESULTS: At 3-month follow-up, psychosocial counselling patients showed high improvements with respect to the severity of symptoms of depression and anxiety. In addition, they reported a reduction of psychosocial stressors and showed an enhancement of coping strategies. At the same time, the severity of symptoms, the quantity of psychosocial stressors and coping mechanisms did not improve in patients receiving routine medical treatment. CONCLUSION: These results indicate that psychosocial counselling can be an effective treatment for mental illnesses even for those living in ongoing unsafe environments.

RESUMO

BACKGROUND: Human beings from time immemorial have eradicated neighbouring tribes, languages, religions, and cultures. In war and crisis, the cumulative exposure to traumatic stress constitutes a predictor of the development of post traumatic stress disorder (PTSD). However, homicide has evolved as a profitable strategy in man, leading to greater reproductive success. Thus, an evolutionary advantage of perpetrating violence would be eliminated if the exposure to aggressive acts would traumatize the perpetrator. We argue that perpetrating violence could actually 'immunize' a person against adverse effects of traumatic stressors, significantly reducing the risk of developing PTSD. METHODS: We surveyed 42 former child soldiers in Northern Uganda that have all been abducted by the Lord Resistance Army (LRA) as well as 41 non-abducted controls. RESULTS: Linear regression analyses revealed a dose-response effect between the exposure to traumatic events and the Posttraumatic Diagnostic Scale (PDS) sum score. However, the vulnerability to develop trauma related symptoms was reduced in those with higher scores on the Appetitive Aggression Scale (AAS). This effect was more pronounced in the formerly abducted group. CONCLUSIONS: We conclude that attraction to aggression when being exposed to the victim's struggling can lead to a substantial risk-reduction for developing PTSD.

RESUMO

Objectives of this study were to compare rates of mental health disorders in Rwandan genocide perpetrators with those of genocide survivors and to investigate potential predictors of symptoms of posttraumatic stress disorder (PTSD) and depression for both groups. We expected high rates of mental disorders in both study groups and hypothesized that symptom severity would be predicted by female gender, older age, lower level of education, higher level of trauma exposure, lower level of agreement to reconciliation, and the participation in killing. Structured clinical interviews were carried out with 269 imprisoned perpetrators (66% men) and 114 survivors (64% women). Significantly more survivors than perpetrators met symptom criteria for PTSD (46% vs. 14%) and suffered from anxiety symptoms (59% vs. 36%). A substantial proportion of both groups suffered from clinically significant depression (46% vs. 41%). PTSD severity in perpetrators was associated with trauma exposure, high levels of agreement to reconciliation, and no participation in killing; the severity of depression was associated with trauma exposure and no participation in killing. In the survivor sample, the severity of PTSD and depression were both correlated with female gender, trauma exposure, and low levels of agreement to reconciliation. Results suggest that both groups exhibit considerable psychiatric morbidity.

RESUMO

Exposure to community violence is common in South Africa and negatively impacts on biopsychosocial health. Posttraumatic stress disorder (PTSD) is characterised by symptoms of intrusion, avoidance, hypervigilance and negative alterations in cognition and mood, and can develop consequent to trauma exposure. Individuals who repeatedly experience and witness violence may also come to view it as appealing and rewarding. This appetitive aggression (AA) increases the likelihood of perpetrating violence. Telomeres are repetitive nucleotide sequences that protect the ends of chromosomes. Telomere length (TL) attrition is a stress-sensitive marker of biological aging that has been associated with a range of psychiatric disorders. This study investigated the cross-sectional relationship between TL and symptoms of PTSD and AA in South African men residing in areas with high community violence. PTSD and AA symptom severity was assessed in 290 men using the Posttraumatic Stress Disorder Symptom Scale - Interview (PSS-I) and Appetitive Aggression Scale (AAS), respectively. Quantitative polymerase chain reaction was performed on DNA extracted from saliva and used to calculate relative TL (rTL). Regression models were used to assess the relationships between rTL and PSS-I and AAS scores. Network analyses using EBIC glasso methods were performed using rTL and items from each of the AAS and PSS-I measures. Both PSS-I (p = 0.023) and AAS (p = 0.016) scores were positively associated with rTL. Network analyses indicated that rTL was weakly related to two PSS-I and five AAS items but performed poorly on indicators of centrality and was not strongly associated with measure items either directly or indirectly. The positive association between rTL and measures of AA and PTSD may be due to the induction of protective homeostatic mechanisms, which reduce TL attrition, following early life trauma exposure.

RESUMO

Research on the use of mobile technology in health sciences has identified several advantages of so-called mHealth (mobile health) applications. Tablet-supported clinical assessments are becoming more and more prominent in clinical applications, even in low-income countries. The present study used tablet computers for assessments of clinical symptom profiles in a sample of Burundian AMISOM soldiers (i.e., African Union Mission to Somalia; a mission approved by the UN). The study aimed to demonstrate the feasibility of mHealth-supported assessments in field research in Burundi. The study was conducted in a resource-poor setting, in which tablet computers are predestined to gather data in an efficient and reliable manner. The overall goal was to prove the validity of the obtained data as well as the feasibility of the chosen study setting. Four hundred sixty-three soldiers of the AMISOM forces were investigated after return from a 1-year military mission in Somalia. Symptoms of posttraumatic stress disorder (PTSD) and depression were assessed. The used data-driven approach based on a latent profile analysis revealed the following four distinct groups, which are based on the soldiers' PTSD and depression symptom profiles: Class 1: moderate PTSD, Class 2: moderate depression, Class 3: low overall symptoms, and Class 4: high overall symptoms. Overall, the four identified classes of soldiers differed significantly in their PTSD and depression scores. The study clearly demonstrates that tablet-supported assessments can provide a useful application of mobile technology in large-scale studies, especially in resource-poor settings. Based on the data collected for the study at hand, it was possible to differentiate different sub-groups of soldiers with distinct symptom profiles, proving the statistical validity of the gathered data. Finally, advantages and challenges for the application of mobile technology in a resource-poor setting are outlined and discussed.

RESUMO

Fatigue in persons with multiple sclerosis (PwMS) is severely disabling. However, the underlying mechanisms remain incompletely understood. Recent research suggests a link to early childhood adversities and psychological trait variables. In line with these studies, this paper took a psychodynamic perspective on MS-fatigue. It was hypothesized that fatigue could represent a manifestation of maladaptive coping with intense emotions. The schema therapeutic mode model served as a theoretical and empirically validated framework, linking psychodynamic theory and empirical research methods. The study was based on a data set of N = 571 PwMS that has also served as the basis for another publication. Data was collected online. The Schema Mode Inventory was used to quantify regulatory strategies to cope with emotionally stressful experiences. In addition, depressive symptoms (Beck's Depression Inventory - FastScreen), physical disability (Patient Determined Disease Steps), alexithymia (Toronto Alexithymia Scale-26), adverse childhood experiences (Childhood Trauma Questionnaire), and self-reported fatigue (Fatigue Scale for Motor and Cognitive Functions) were assessed. Latent profile analysis revealed three distinct groups of PwMS, based on their coping mode profiles: (1) PwMS with low maladaptive coping, (2) PwMS with avoidant/submissive coping styles, and (3) PwMS with avoidant/overcompensatory coping styles. Multivariate comparisons showed no significant difference in physical disability across the three groups. However, heightened levels of self-reported fatigue and depression symptoms occurred in PwMS with maladaptive coping styles. A path model uncovered that self-reported fatigue was robustly related to physical disability (ß = 0.33) and detached/avoidant coping (Detached Protector; ß = 0.34). There was no specific relation between any of the maladaptive coping modes and depression symptoms. Detached/avoidant coping was in turn predicted by childhood emotional abuse and neglect. The results indicate that childhood adversity and detached/avoidant coping styles may be associated with variability in MS-fatigue severity: PwMS that resort to detached/avoidant coping in response to negative emotions also tend to report heightened levels of fatigue, although they do not differ in their perceived disability from PwMS with low levels of fatigue and maladaptive coping. A link between MS-fatigue and the psychodynamic traumatic conversion model is discussed. The implications of these findings for therapeutic interventions require further study.

RESUMO

Exposure to violence can lead to appetitive aggression (AA), the positive feeling and fascination associated with violence, and posttraumatic stress disorder (PTSD), characterised by hyperarousal, reexperience and feelings of ongoing threat. Psychotherapeutic interventions may act via DNA methylation, an environmentally sensitive epigenetic mechanism that can influence gene expression. We investigated epigenetic signatures of psychotherapy for PTSD and AA symptoms in South African men with chronic trauma exposure. Participants were assigned to one of three groups: narrative exposure therapy for forensic offender rehabilitation (FORNET), cognitive behavioural therapy or waiting list control (n = 9-10/group). Participants provided saliva and completed the Appetitive Aggression Scale and PTSD Symptom Severity Index at baseline, 8-month and 16-month follow-up. The relationship, over time, between methylation in 22 gene promoter region sites, symptom scores, and treatment was assessed using linear mixed models. Compared to baseline, PTSD and AA symptom severity were significantly reduced at 8 and 16 months, respectively, in the FORNET group. Increased methylation of genes implicated in dopaminergic neurotransmission (NR4A2) and synaptic plasticity (AUTS2) was associated with reduced PTSD symptom severity in participants receiving FORNET. Analyses across participants revealed a proportional relationship between AA and methylation of TFAM, a gene involved in mitochondrial biosynthesis.

RESUMO

Why are savagery and violence so omnipresent among humans? We suggest that hunting behaviour is fascinating and attractive, a desire that makes temporary deprivation from physical needs, pain, sweat, blood and, ultimately, the willingness to kill tolerable and even appetitive. Evolutionary development into the "perversion" of the urge to hunt humans, that is to say the transfer of this hunt to members of one's own species, has been nurtured by the resultant advantage of personal and social power and dominance. While a breakdown of the inhibition towards intra-specific killing would endanger any animal species, controlled inhibition was enabled in humans in that higher regulatory systems, such as frontal lobe-based executive functions, prevent the involuntary derailment of hunting behaviour. If this control--such as in child soldiers for example--is not learnt, then brutality towards humans remains fascinating and appealing. Blood must flow in order to kill. It is hence an appetitive cue as is the struggling of the victim. Hunting for men, more rarely for women, is fascinating and emotionally arousing with the parallel release of testosterone, serotonin and endorphins, which can produce feelings of euphoria and alleviate pain. Bonding and social rites (e.g. initiation) set up the constraints for both hunting and violent disputes. Children learn which conditions legitimate aggressive behaviour and which not. Big game hunting as well as attack of other communities is more successful in groups--men also perceive it as more pleasurable. This may explain the fascination with gladiatorial combat, violent computer games but as well ritualized forms like football.

RESUMO

BACKGROUND AND OBJECTIVES: Retraining, a psychological intervention derived from the approach-avoidance paradigm, has yielded mixed results for the treatment of alcohol use disorder as well as other forms of addiction. The present study investigated the efficacy of an imaginal variant of retraining that allowed greater personalization of the content. METHODS: Within the framework of a randomized controlled trial (RCT), 84 individuals with self-reported alcohol-related problems were recruited over the Internet and allocated to either imaginal retraining (treatment manual dispatched as a pdf-file via email) or a wait-list control group (with care-as-usual). The intervention period was four weeks. Alcohol craving, as measured with a visual analogue scale (VAS), served as the primary outcome. Other emotional (e.g. self-esteem) and drinking-related variables served as secondary outcomes. RESULTS: Both per-protocol (PP) and intention-to-treat (ITT) analyses showed that imaginal retraining led to a significant reduction in alcohol craving compared to the control group at a large effect size. Self-esteem improved in the retraining condition relative to controls in the PP and one of the ITT analyses; 75% of the individuals in the treatment group reported less alcohol consumption in the treatment period, whereas drinking behavior remained essentially unchanged in the control group (p < .001) (the trial was registered at the German Clinical Trials Register, DRKS00015319). LIMITATIONS: Whether the effects of imaginal retraining are sustained over time needs to be established. Attrition was significantly higher in the retraining group (40.5%) than in the control group (16.7%). Designs with an active control condition are needed as well as dismantling studies to explore which of the treatment's multiple components best predicts improvement. Future studies should verify participants' alcohol consumption levels using objective measures. CONCLUSION: Imaginal retraining led to significant effects on the reduction of alcohol craving.

RESUMO

BACKGROUND: Latest research demonstrates a significant improvement in stress-related symptoms in psychological disorders as a result of exercise training (ET). Controlled clinical trials further validate the significance of ET by demonstrating lower salivary cortisol levels in patients with post-traumatic stress disorder (PTSD) after intervention. A significant change in cortisol and dehydroepiandrosterone (DHEA) levels can already be found after an 8-12-week ET program. The proposed study aims to investigate the impact of an 8-week ET on PTSD symptoms and changes in cortisol levels in a juvenile refugee sample from the Democratic Republic of the Congo (DRC) at an Ugandan refugee settlement. It is the first to implement an ET intervention in a resource-poor, post-conflict setting. METHODS/DESIGN: In a randomized controlled trial, 198 adolescent participants aged 13-16 years from the DRC who, suffer from PTSD, will be investigated. The participants are based at the Nakivale refugee settlement, an official refugee camp in Uganda, Africa, which is among the largest in the world. The participants will be randomized into an Exercise Training (ET) group with a maximum heart rate (HRmax) of > 60%, an Alternative Intervention (AI) group with low-level exercises, and a Waiting-list Control (WC) group. After the 8-week interventional phase, changes in cortisol awakening response (CAR) and DHEA in the ET group that correspond to an improvement in PTSD symptoms are expected that remain at follow-up after 3 months. DISCUSSION: To date, there is no controlled and reliable longitudinal study examining the effects of an ET program on symptom severity in individuals with PTSD that can be explained with a harmonization of cortisol secretion. The presented study design introduces an intervention that can be implemented with little expenditure. It aims to provide a promising low-threshold and cost-effective treatment approach for the application in resource-poor settings. TRIAL REGISTRATION: German Trials Register, ID: DRKS00014280 .

RESUMO

Appetitive aggression is a sub-category of instrumental aggression, characterised by the primary intrinsic enjoyment of aggressive activity. Aggression is heritable, and serotonergic and monoaminergic neurotransmitter systems have been found to contribute to the underlying molecular mechanisms. The aim of this study was to investigate the role that genetic variants in the serotonin transporter (SLC6A4) and monoamine oxidase A (MAOA) genes play in the aetiology of appetitive aggression in South African Xhosa males (n = 290). SLC6A4 5-HTTLPR, rs25531, and STin2 variants, as well as MAOA-uVNTR were investigated for their association with levels of appetitive aggression using Poisson regression analysis. The STin2 VNTR12 allele was found to be associated with increased levels of appetitive aggression (p = 0.003), but with decreased levels of reactive aggression (p = 7 × 10-5). This study is the first to investigate genetic underpinnings of appetitive aggression in a South African population, with preliminary evidence suggesting that SCL6A4 STin2 variants play a role in its aetiology, and may also be important in differentiating between appetitive and reactive aggression. Although the results require replication, they shed some preliminary light on the molecular dichotomy that may underlie the two forms of aggression.

RESUMO

The ability to produce peak performance plays a decisive role in the success of athletes in competitive contest situations. Levels of appetitive competition motivation (ACM), i.e., the desire to defeat an opponent independent of secondary reinforcing factors, were assessed in professional female football/soccer players in the premier and regional leagues, using club level as the measurement of sport success. Furthermore, the influence of social environments predominantly encouraging masculine and competitive play behavior and the players' perceptions of their own gender role orientations were investigated. Ninety female football players from the German premier league (44) and regional leagues (46) participated (age: M = 24, SD = 5 years). Questionnaires ascertaining ACM and self-perceptions of gender via gender-role stereotypes, childhood play behavior and style of upbringing were utilized. Premier league athletes showed a significantly greater inclination toward direct sporting confrontations. Almost 50% of the variance in ACM between the premier and regional league athletes was determined by modern upbringing style and the development of gender roles not corresponding to classic female gender stereotypes. The results emphasize the significance of ACM as an important facet in competitive sports and illustrate the influence of socialization on athletic performance.

RESUMO

OBJECTIVE: In an observer-blinded intervention trial, we tested the reduction of posttraumatic stress symptoms, aggressive attitude, and behavior in young males living in a context of ongoing community and gang violence by means of (a) forensic offender rehabilitation narrative exposure therapy (FORNET), and (b) the cognitive-behavioral intervention "Thinking for a Change" (TFAC). A waiting list served as the control condition. METHOD: A total of 39 young men were included in the data analysis: 15 completed FORNET, 11 underwent cognitive-behavioral therapy (CBT), and 13 were on a waiting list for later treatment. The primary efficacy endpoints were the PTSD Symptom Scale-Interview (PSS-I) severity score, the Appetitive Aggression Scale (AAS) score, and the number of perpetrated violent event types 8 months (on average) after treatment. RESULTS: Only in the sample receiving FORNET were posttraumatic stress disorder (PTSD) scores significantly reduced at the first follow-up (Cohen's d = -0.97) and significantly different from those of the control group (Cohen's d = -1.03). The changes in scores for appetitive aggression and perpetrated events were not significant for any of the treatment conditions. CONCLUSIONS: The study shows that trauma-focused treatment can reduce the psychological symptoms of posttraumatic stress even for individuals living under unsafe conditions in low-income urban communities. However, achieving changes in violent behavior within a context of ongoing violence may require more than the treatment of trauma-related suffering, confrontation with one's offenses, or cognitive-behavioral interventions.

RESUMO

BACKGROUND: In persistently unsafe environments, the cumulative exposure to violence predicts not only the development of posttraumatic stress disorder (PTSD), but also of increased aggression and violent outbursts. Substance use disorders interact with these developments, as drug consumption may blunt symptoms and also reduce the threshold for violent acts. Investigating the interplay between these variables and the possible cumulative effect of drug abuse on the attraction to cruelty is a crucial step in understanding the cycle of violence and developing intervention programs that address this cycle in violence-troubled communities such as low-income urban areas in South Africa. METHODS: Young males at risk (N=290) were recruited through a reintegration center for offenders in Cape Town. We assessed types of traumatic events experienced, PTSD symptom severity, appetitive aggression, committed offenses and patterns of drug abuse prior to the perpetration of violence. RESULTS: Path-analyses confirmed a positive relationship between exposure to traumatic events and PTSD symptom severity, appetitive aggression, the number of committed offenses and drug abuse prior to violence. PTSD symptoms were positively associated with the propensity toward aggression. Furthermore, more severe drug abuse was related to higher attraction to violence and more committed offenses. CONCLUSIONS: We conclude that like exposure to violence, drug abuse may play a key role in the attraction to aggression and criminal acts. Measures of violence prevention and psychotherapeutic interventions for trauma-related suffering may not be effective without enduring drug abuse rehabilitation.

RESUMO

OBJECTIVE: Past research revealed war trauma and posttraumatic stress disorder (PTSD) symptoms as potential predictors for domestic and community violence in crisis regions and among soldiers in different armed conflicts. The impact of family violence and other adversities experienced in childhood as well as of a combat-enhanced appeal for aggressive behavior (appetitive aggression) remains to be specified. METHOD: In the present study, the authors separately predicted violence against children, intimate partner violence and community violence in 381 Burundian soldiers returning from foreign deployment and living in a post- conflict region. Using path analysis, they aimed to disentangle the independent contributions and pathways of the following variables: Exposure to war trauma and childhood familial violence, PTSD and depression symptom severity, and appetitive aggression. RESULTS: Childhood familial violence had an independent effect on all contexts of violence and was the only significant predictor for violence against the soldiers' own children. Intimate partner violence was additionally predicted by depression symptom severity, while community violence was additionally predicted by PTSD symptom severity and appetitive aggression. CONCLUSIONS: Besides war-related mental ill-health and appetitive aggression, violent experiences during childhood development must not be overlooked as a factor fueling the cycle of violence in conflict regions.

RESUMO

Post-Traumatic Stress Disorder (PTSD) has been linked to deviations in lateralized frontal functional oscillatory activity. This is possibly because left and right DLPFC have differential roles in regulating both memory and stress response, which are both dysfunctional in PTSD. However, previous results are heterogeneous, and could be attributable to individual symptom clusters, traumatic or aggressive life events, early life stress, or the interaction of these factors. In a large sample of active combatants (N=401), we regressed these factors on frontal electroencephalography (EEG) asymmetry across 5 frequency bands (delta: 2-4Hz; theta: 4-8Hz; alpha: 8-12Hz; beta: 12-24Hz; gamma: 24-48Hz). Negative cognition and mood was associated with stronger relative left delta and theta band power. Traumatic life events showed stronger right alpha and beta band power. Traumatic life events in interaction with hyperarousal predicted stronger relative right left-right imbalance (theta, alpha, and beta bands), whereas childhood adversity, in interaction with negative cognition and mood, predicted stronger relative left left-right imbalance (delta, theta, alpha and beta bands). The contribution of lateralized DLPFC dysfunction to PTSD is thus dependent on the individual complexities of subsymptom clusters and life history, and future studies need to take these factors into account.
