ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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 .

ABSTRACT

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.

ABSTRACT

Background: In violent communities, social rejection as a person with victim-offender attributes is associated with more intense symptoms of posttraumatic stress disorder (PTSD) and a higher propensity towards violence, i.e. appetitive aggression. Successful community reintegration encompassing adequate social acknowledgment of individuals with both a history of violence exposure and perpetration may be necessary to enhance the treatment effects of interventions addressing PTSD and aggression. Objective: In this study, the effects of treatment and post-treatment traumatic events, violent offenses, and social acknowledgment (with sub-dimensions of general disapproval, family disapproval, and recognition as a person with both a history of violence exposure and commission) on changes in PTSD symptom severity and appetitive aggression from baseline to 8-month follow-up were investigated. Method: Data were collected from 54 males recruited through a Cape Town offender reintegration programme for an intervention study targeting trauma and aggression (n = 28 treatment; n = 26 wait-list). Changes in PTSD symptom severity after treatment were assessed with the PTSD Symptom Scale-Interview, changes in appetitive aggression with the Appetitive Aggression Scale (AAS), post-treatment traumatic events with an adapted version of the Child's Exposure to Violence Checklist, offenses with an adapted checklist from the AAS, and social acknowledgment with an adapted form of the Social Acknowledgment Questionnaire. Results: Path analyses revealed negative relationships between ongoing societal disapproval and changes in PTSD symptom severity and appetitive aggression at 8-months, controlling for age. All other variables were non-significant, except for treatment, which was associated with PTSD symptom reduction. Conclusions: As a complementary strategy to effective psychotherapeutic treatment, increased social acknowledgment may contribute significantly to the alleviation of PTSD symptoms and appetitive aggression. Psychological interventions should, therefore, not neglect the impact of societal factors on treatment effects.


Planteamiento: En comunidades violentas, el rechazo social como persona con atributos de víctima-agresor se asocia con síntomas más intensos del trastorno por estrés postraumático (TEPT) y una mayor propensión a la violencia, es decir, a la apetencia por la agresión. Puede que sea necesaria una reintegración con éxito en la comunidad ­que incluya un adecuado reconocimiento social de aquellos individuos con una historia tanto de exposición a la violencia como de agresión­ para mejorar los efectos del tratamiento de las intervenciones que abordan el TEPT y la agresión.Objetivo: En este estudio, se investigaron los efectos del tratamiento y los eventos traumáticos post-tratamiento, los delitos violentos y el reconocimiento social (con subdimensiones de desaprobación general, desaprobación familiar y reconocimiento como persona con antecedentes tanto de exposición a la violencia como de perpetración) sobre los cambios en la gravedad de los síntomas del TEPT y la apetencia por la agresión desde el inicio hasta el seguimiento a los 8 meses.Método: Se recogieron datos de 54 varones reclutados a través de un programa de reintegración de delincuentes de Ciudad del Cabo para un estudio de intervención dirigido a trauma y agresión (n = 28 tratamiento, n = 26 lista de espera). Se evaluaron los cambios en la gravedad de los síntomas del TEPT después del tratamiento con la Escala-Entrevista de Síntomas de TEPT (PTSD Symptom Scale-Interview), los cambios en la apetencia por la agresión con la Escala de Apetencia por la Agresión (AAS, siglas en ingles de Appetitive Aggression Scale), los eventos traumáticos posteriores al tratamiento con una versión adaptada de la Lista de verificación de exposición a la violencia para niños (Child's Exposure to Violence Checklist), las agresiones con una lista de verificación adaptada del AAS, y el reconocimiento social con una forma adaptada del Cuestionario de Reconocimiento Social (Social Acknowledgment Questionnaire).Resultados: Los análisis de ruta revelaron relaciones negativas entre la desaprobación social continuada y los cambios en la gravedad de los síntomas del TEPT y la apetencia por la agresión a los 8 meses, controlando la edad. Todas las demás variables no fueron significativas, excepto por el tratamiento, que se asoció con la reducción de los síntomas de TEPT.Conclusiones: Como estrategia complementaria a un tratamiento psicoterapéutico efectivo, el aumento del reconocimiento social puede contribuir significativamente al alivio de los síntomas del TEPT y la apetencia por la agresión. Por lo tanto, las intervenciones psicológicas no deben descuidar el impacto de los factores sociales sobre los efectos del tratamiento.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

BACKGROUND: Life in the low-income urban communities of South Africa is imprinted by a cycle of violence in which young males predominantly are in the roles of both victim and perpetrator. There is some evidence that adolescents who show an attraction to cruelty can display high levels of psychosocial functioning despite the presence of posttraumatic stress symptoms. However, the role of appetitive aggression in the context of ongoing threats and daily hassles is not yet fully understood. OBJECTIVE: In this study, we examine the role of attraction to violence in areas of continuous traumatic stress exposure and its effect on posttraumatic stress disorder (PTSD) severity and violence perpetration. METHOD: A sample of 290 young males from two low-income Cape Town communities was surveyed. We assessed appetitive aggression with the Appetitive Aggression Scale (AAS), PTSD symptoms with the PTSD Symptom Scale-Interview, the number of witnessed and self-experienced traumatic event types with an adaptation of the Child Exposure to Community Violence questionnaire, and the number of perpetrated violence event types with an adapted offence checklist from the AAS. RESULTS: Appetitive aggression scores were predicted by witnessed as well as self-experienced traumatic events. Higher appetitive aggression scores resulted in higher levels of PTSD severity and perpetrated violence. CONCLUSIONS: Young males living in the low-income areas of South Africa may develop an attraction to cruelty in response to exposure to violence. Their willingness to fight in turn can increase the likelihood of continued violent behaviour. In contrast to previous research from postconflict areas, appetitive aggression and engagement in violence do not prevent the development of PTSD, but are instead associated with higher levels of posttraumatic stress. PTSD symptoms such as avoidance and hyperarousal, as well as an attraction to cruelty and thus the willingness to fight, might support survival in areas of ongoing conflict, but at the same time they could fuel the cycle of violence.

ABSTRACT

The scent of blood is potentially one of the most fundamental and survival-relevant olfactory cues in humans. This experiment tests the first human parameters of perceptual threshold and emotional ratings in men and women of an artificially simulated smell of fresh blood in contact with the skin. We hypothesize that this scent of blood, with its association with injury, danger, death, and nutrition will be a critical cue activating fundamental motivational systems relating to either predatory approach behavior or prey-like withdrawal behavior, or both. The results show that perceptual thresholds are unimodally distributed for both sexes, with women being more sensitive. Furthermore, both women and men's emotional responses to simulated blood scent divide strongly into positive and negative valence ratings, with negative ratings in women having a strong arousal component. For women, this split is related to the phase of their menstrual cycle and oral contraception (OC). Future research will investigate whether this split in both genders is context-dependent or trait-like.

ABSTRACT

BACKGROUND: During the period between 1993 and 2005, the people of Burundi were trapped within a violent civil war. In post-conflict regions, symptoms of posttraumatic stress disorder (PTSD) were found to be widespread. At the same time, combatants often reported having perceived committing violence as exciting and appealing, an experience referred to as appetitive aggression. Both of these phenomena hamper the building of a functional and peaceful society. OBJECTIVE: This study aims to investigate the factors that are associated with the level of PTSD and appetitive aggression in former and still active combatants. METHODS: Semi-structured interviews were conducted with 948 male Burundians: 556 active soldiers and 392 ex-combatants. PTSD symptom severity was assessed using the PTSD Symptom Scale Interview, while appetitive aggression was assessed using the Appetitive Aggression Scale. RESULTS: Linear regression analyses revealed that the number of traumatic events, childhood maltreatment, and their interaction predicted PTSD symptom severity, whereas self-committed violence did not. The number of traumatic events and self-committed violence were associated with appetitive aggression. Childhood maltreatment alone was not associated with appetitive aggression; however, its interaction with self-committed violence did predict appetitive aggression. When controlling for predictors, ex-combatants reported a higher degree of PTSD symptomatology, whereas active soldiers reported a higher degree of appetitive aggression. CONCLUSION: We conclude that childhood maltreatment is an additional, significant risk factor that exacerbates the psychological consequences of violent conflicts. Self-committed violence may not necessarily engender trauma-related disorders, but is highly related to appetitive aggression.
