¿En qué se diferencian las agresiones sexuales cometidas en solitario y en grupo? Una revisión sistemática / How are solo versus multiple perpetrator sexual assaults different? A systematic review

Resumen El estudio de las agresiones sexuales ha tenido una gran relevancia e interés en la literatura. Las agresiones sexuales en grupo representan una pequeña proporción de todas las agresiones sexuales cometidas, pero presentan unas características específicas. La presente revisión sistemática examinó las variables de los delitos de agresión sexual cometidos en solitario versus en grupo. Se realizó una búsqueda bibliográfica en las bases de datos Psycinfo, Academic Search (EBSCO) y Google Scholar, y se encontraron ocho documentos que cumplían las condiciones de inclusión. Los resultados muestran que existe evidencia de las diferencias cualitativas entre las agresiones sexuales cometidas según el número de infractores. Las dinámicas que se promueven en los grupos explican la participación de los sujetos en las agresiones sexuales en grupo. El comportamiento colectivo favorece las agresiones sexuales en grupo por los procesos inherentes a él. Los delincuentes son, en su mayoría, hombres. Los delincuentes solitarios tienen una mayor edad y, a medida que los grupos son más grandes, la edad de los agresores disminuye. En cuanto a las víctimas, son más jóvenes que los agresores, sobre todo en los casos perpetrados por múltiples sujetos, y ofrecen una mayor resistencia ante las agresiones en solitario. Se ha confirmado que en las agresiones en grupo se llevan a cabo más actos sexuales y se utiliza más la violencia. Por otro lado, no aparecen diferencias en cuanto al uso de alcohol y la presencia de armas en las agresiones. Estos resultados tienen implicaciones para la prevención del delito y el tratamiento de las víctimas.

Abstract The study of sexual assault has had great relevance and interest in the literature. Group sexual assaults represent a small proportion of all sexual assaults committed, but they have specific characteristics. Internationally, it is established that between 10 and 33 % of sexual assaults have been committed by multiple authors. Describing the differences between individual versus group sexual assaults has been a challenge for researchers. The literature has concluded that there is a difference in the etiology of sexual assaults committed according to the number of authors. While in solo sexual assaults personal vulnerability factors may explain why these crimes are committed, in group assaults group behavior dynamics explain the interaction between more subjects. This systematic review examined the variables of sexual assault crimes committed alone versus in a group. A literature search was conducted on the Psycinfo, Academic Search (EBSCO) and Google Scholar databases. In the first analysis a total of 34 studies were initially identified, and after filtering the reasons for exclusion the analysis was performed with eight investigations. The results show that there is evidence of qualitative differences between sexual assaults committed according to the number of offenders. The dynamics promoted in the groups explain the subjects' participation in group sexual aggressions. Collective behavior favors sexual aggressions in groups because of the processes inherent to the group. The most common group was two subjects (dyad) although the average group was usually composed of three subjects. The offenders are mostly men; the lone offenders are older, and as the groups become larger, the age of the offenders decreases. Research has shown that the majority of victims are female, both in single and group assaults. Victims are also younger than the perpetrators, especially in multi-subject attacks, and they are more resistant to single-aggression attacks. The place where the crime is committed presents significant differences. Some authors found that offenders in groups of three or more people often commit the assault in an indoor space, although others found that lone offenders were more likely than group offenders to rape the victim indoors, especially in the bedroom. It has been confirmed that in group aggressions more sexual acts are carried out and more violence is used. Vaginal penetration is the most committed sexual assault, followed by anal and oral rape. In all cases, vaginal rape is more prevalent among group sexual assaults, even more so when the assaults are committed by groups of three or more subjects. Studies of multiple perpetrator sexual assaults show that this type of act increases the probability of suffering more injuries and long-term health problems. Another conclusion that can be drawn is that there are significant differences in the timing of stranger assault, with a higher likelihood of a stranger assault in group rapes. On the other hand, there is also a relevance in the presence of other instrumental factors such as alcohol and weapons. As for alcohol, it showed a significant relationship in sexual assaults. Although the presence of weapons in sexual assaults is not very common, some research has confirmed that groups tend to threaten victims with a weapon to a greater extent, and the knife is often the most common weapon. The results found are particularly relevant to understanding sexual assault crimes and have implications for crime prevention and the treatment of victims.

The demographic profile of the female assailant: A ten-year background review of female perpetrators committing abuse seen at the Philippine General Hospital Child Protection Unit from January 2008 to December 2018

Objectives@#There is limited information on the demographics of female perpetrators of child abuse hence its profile was described utilizing the records collected at the University of the Philippines – Philippine General Hospital Child Protection Unit from January 2008-December 2018. @*Methods@#A retrospective review of the electronic records using the Child Protection Management Information System (CPMIS) database was done using descriptive and inferential analyses. Total enumeration was done for the descriptive analysis and categorical data was analyzed using frequencies and percentages. Inferential analysis using chi-squared analysis or Fisher’s exact probability test was used using a minimum sample size computed using power analysis @*Results@#A total of 983 female perpetrators were reported, mostly belonging to the age group of 25-34 years old (23%). They were more frequently a close relative to the victim (47.3%). Half (50%) of the perpetrators had history of substance abuse, and 65.5% witnessed family violence. Criminal history (99.8%) and occupation (46.7%) were mostly unknown. The types of abuse committed were mostly physical (36%) followed by sexual abuse (34.9%). Inferential analysis of the data suggested that the demographic variables associated with physical abuse were age group, relationship, and history of substance abuse. Meanwhile, age group, relationship, and occupation were associated with sexual abuse. @*Conclusion@#Although we see a greater number of male perpetrators, it cannot be denied that female perpetrators can also cause harm to the vulnerable population. It is alarming to note that majority of them are close relatives to the victim. Data from the study can help raise awareness and increase vigilance on possible at-risk population.

Creencias sobre la violencia y sus efectos en la prevalencia de la violencia en el noviazgo / Beliefs about violence and its effects on the prevalence of dating violence

Resumen La violencia en el noviazgo es un fenómeno multifactorial que requiere de estudios que profundicen respecto a los efectos que tienen las creencias culturales en el comportamiento tanto del agresor como de la víctima. Teniendo esto en cuenta, el objetivo de la presente investigación fue determinar la relación entre las creencias acerca de la violencia y la prevalencia de la violencia en el noviazgo. Para ello, se contó con una muestra de 420 estudiantes de dos universidades públicas mexicanas que respondieron el Inventario de creencias acerca de la violencia hacia la esposa, el Inventario de conflictos en las relaciones de noviazgo, y un cuestionario de información sociodemográfica. Los datos recolectados fueron examinados por medio de un análisis de correlación canónica, y los resultados mostraron que el modelo en general fue estadísticamente significativo (Wilks X = .654, F(20, 677.54) = 4.626,p < .05); que el tamaño del efecto del modelo general fue de .346, lo que indica que este explicó el 34.6 % de la varianza compartida por los dos conjuntos de variables; y que, específicamente en la primera función, el coeficiente de mayor magnitud fue el de la variable de justificación de la violencia (r2 s = 76.2; h 2 = 90.0), seguido por la del apoyo que se le puede brindar a la víctima (r2 s = 57.1; h2 = 94.5).

Abstract Dating violence is a multifactorial phenomenon that requires in-depth studies regarding the effects that cultural beliefs have on the behavior of both the aggressor and the victim. With this in mind, the objective of this research was to determine the relationship between beliefs about violence and the prevalence of dating violence. To this end, a sample of 420 students from two Mexican public universities answered the Inventory of Beliefs about Wife Violence, the Inventory of Conflicts in Dating Relationships, and a sociodemographic information questionnaire. The data collected were examined through a canonical correlation analysis, and the results showed that the overall model was statistically significant (Wilks X = .654, F (20, 677.54) = 4.626, p < .05); that the effect size of the overall model was .346, indicating that it explained 34. 6 % of the variance shared by the two sets of variables; and that, specifically in the first function, the coefficient of greatest magnitude was that of the variable of justification of the violence (r2 s = 76.2; h2 = 90.0), followed by that of the support that can be given to the victim (r2 s = 57.1; h2 = 94.5).

Caracterização, reincidência e percepção de homens autores de violência contra a mulher sobre grupos reflexivos / Caracterización, reincidencia y percepción de hombres autores de violencia contra la mujer sobre grupos reflexivos / Characterization, recidivism and perception of men perpetrators of violence against women about reflective groups

RESUMO Este estudo busca caracterizar homens autores de violência contra mulheres (HAV) que participaram de Grupos Reflexivos (GR) do Núcleo Especializado de Atendimento ao Homem ao Autor de Violência Doméstica e Familiar (NEAH) em Belém-PA, com destaque para a reincidência e a percepção dos HAV sobre os GR. Trata-se de um estudo documental, com registros feitos entre 2012 e 2015. Entre os resultados, verificou-se que 33,8% desses homens (n=24) não haviam completado o Ensino Fundamental, 58,8% (n=40) eram usuários de álcool e 54,8% (n=40) conviviam com a mulher no momento da agressão. Ademais, 61,2% (n=41) deles foram processados por violência física contra a mulher, mas apenas 1,3% (n=1) reincidiram nesta forma de agressão após a participação no GR. Estes foram descritos como um mecanismo acessível na prevenção da violência, pois proporciona cuidado, aprendizado e reflexão, porém, demanda por maiores pesquisas e investimentos que se aproximem de outras políticas sociais a fim de construir uma rede sólida de reformulação das relações sociais de gênero.

ABSTRACT This study seeks to characterize men who were perpetrators of violence against women (HAV) and their participation in Reflexive Groups (GR) of the Nucleus X in Belém-PA, Brazil, highlighting the recidivism and the perception of HAV about GR. This is a documentary study with records made between 2012 and 2015. Among the results, 33.8% of these men (n = 24) did not complete Elementary School, 58.8% (n = 40) were alcohol users, 54.8% (n = 40) lived with the woman at the time of the aggression. In addition, 61.2% (n = 41) were prosecuted for physical violence against women, but only 1.3% (n = 1) relapsed in this form of aggression after participating in the GR. These have been described as an accessible mechanism in the prevention of violence that provides care, learning and reflection, demand for more research and investments that approach other social politics in order to build a solid network of reformulation of social relations of gender.

Treatment of Dissociative Symptoms and Depression as a Consequence of Mother's Neglect during Childhood, using EMDR: Two Case Studies

The present study reports two cases where clients (age 19 -23 yrs) suffer from major depressive disorderalong with dissociative symptoms. History revealed emotional unavailability, neglect, and physical andverbal abuse by mother. Clients were assessed on Dissociative experience scale (DES) and BeckDepression inventory (BDI). Psychotherapeutic intervention was provided. Clients responded well withEye Movement Desensitization and Reprocessing (EMDR) and after almost one year of treatment, showimprovement in their DES and BDI scores. They become assertive to cope with the situation at home andstable enough to carry out their day to day life. In both the above mentioned cases, mother’s emotionalabuse and emotional neglect during childhood produced the long term impact, thus generating a negativeself schema and flawed perception of outer world which resulted in PTSD as well as dissociativesymptoms and depression. Their shattered ego required a long preparation phase. EMDR helped them inhealing and in enhancing their coping pattern

Experiences of intimate partner violence as perpetrated among Japanese university freshmen / Journal of Rural Medicine

Objectives: To compare experiences regarding the perpetration of intimate partner violence among Japanese university freshmen between 2008 and 2014.Study design: Two-stage cross-sectional study.Methods: A self-administered questionnaire survey was completed in both 2008 and 2014 by students at the same university.Results: There were significant reductions in episodes of verbal harassment (adjusted odds ratio [AOR]: 0.601, 95% confidence interval [CI]: 0.382, 0.945, P = 0.027) that occurred when a boy/girlfriend said “you don’t give me priority” to his/her partner when they did not see them (AOR: 0.450, 95%CI: 0.207, 0.979, P = 0.044), and also in instances of irritation that resulted when a boy/girlfriend disobeyed his/her partner (AOR: 0.385, 95%CI: 0.161, 0.921, P = 0.032) from 2008 to 2014. The perpetration scores were reduced from 1.87 ± 0.16 in 2008 to 1.41 ± 0.117 in 2014 (t test, P = 0.016). The perpetration scores in 2014 were significantly lower than those in 2008, regardless of gender, age, university faculty, and participation in lectures/seminars about domestic violence (DV) and/or dating DV (P = 0.030).Conclusions: Findings showed reductions in some types of harassment, as well as in perpetration scores, between 2008 and 2014 among Japanese university freshmen at the same university. However, further study is required to determine the factors related to the perpetration of harassment.

La violencia intrafamiliar se ha convertido en un fenómeno estructural de la sociedad, cobra innumerables víctimas que van desde el maltrato de palabra pasando por el psicológico, el económico, el sexual hasta llegar al daño en la integridad física. La pérdida de años de vida, las incapacidades permanentes o transitorias y la perpetuación del círculo vicioso hacen que este problema se convierta en un reto para la salud pública y para la sociedad en general. Mediante un estudio descriptivo retrospectivo en una población de 374 casos registrados en la Comisaría de Familia de Funza, Cundinamarca, se evaluaron los principales eventos violentos generados al interior de la familia y las más importantes características socio demográficas de sus actores. Se concluye que el grupo poblacional de adultos jóvenes es quien más sufre la agresión y dentro de este grupo, son las mujeres las más agredidas, el violentador es generalmente de la familia y conocido, y en la mayoría de los casos son los mismos agredidos quienes colocan la queja. Por otra parte la violencia verbal y la económica son las más frecuentes seguidas de la psicológica y la física.(AU)

Family violence in its multiple forms, i.e, verbal aggression, psychological, economical, sexual and physical abuse, has become a structural phenomenon of society which yields countless victims. The loss of years of life, the transient or permanent leaves from work , and perpetuation of its vicious circle make of it a challenge for public health in general and for society as a whole. The main violent events generated within the family and the principal characteristics of its actors were assessed by means of a retrospective study in a population of 374 registered cases reported to the police station specialized in family affairs of the town of Funza, Cundinamarca. Young adults are the group of population which most frequently suffer these aggressions and within it women are most often offended. The person responsible for this violence is usually someone known within the family group and in the majority of cases the victims themselves maid the claim.
