Psychometric validation of the audio-guided rBVQ instrument for bullying evaluation among students / Validação psicométrica do instrumento áudio-guiado rBVQ para avaliação de bullying / Validación psicométrica del instrumento audio guiado rBVQ para la evaluación del bullying

The revised Olweus Bully/Victim Questionnaire (rBVQ) is an internationally used instrument to identify bullying, but due to Brazilian students' low proficiency in reading and writing, it had to be adapted for audio-guided use through smartphones. We investigated construct validity, using Confirmatory Factor Analysis (CFA), under a two-correlated factor solution. Participated 1,742 fifth graders and 2,316 seventh graders from 30 public schools in the city of São Paulo. We found excellent fit indices models for both grades (fifth grade: CFI=0.985, RMSEA=0.020; seventh grade: CFI=0.990, RMSEA=0.015), as well as factor loading higher than 0.4 for all items, indicating their relevance to the construct. The rBVQ demonstrated excellent psychometric properties and may help future studies that aim to investigate bullying in populations with similar profiles. In addition, this study innovates by evaluating an audio-guided instrument and using mobile technology. (AU)

The mediating role of alexithymia in the relationship between trait anger and aggressive behavior among male prisoners / 中华行为医学与脑科学杂志

Objective:To explore the mediating role of alexithymia in the relationship between trait anger and aggressive behavior among male violent prisoners.Methods:A sample of 268 male violent prisoners completed self-report measures of the trait anger scale (TAS), Toronto alexithymia scale-20 (TAS-20) and the Chinese college students' version of Buss-Perry aggression questionnaire. SPSS 23.0 software and Mplus 8.0 software were used to test the mediating effect.Results:The total scores of trait anger, aggressive behavior and alexithymia were (17.75±4.93), (52.15±10.61)and (70.90±19.40), respectively. Pearson correlation analysis showed that trait anger was both significantly positively correlated with aggressive behavior ( r=0.67, P<0.01) and alexithymia ( r=0.40, P<0.01), and there was also a significantly positive correlation between alexithymia and aggressive behavior ( r=0.55, P<0.01). Multivariate hierarchical regression analysis showed that trait anger directly predicted aggressive behavior ( β=0.67, P<0.01) after controlling the influence of alcohol addiction. Emotional recognition disorder played a partially mediating role in the relationship between trait anger and aggressive behavior ( β=0.18, 95% CI=0.11-0.27). Conclusion:Trait anger not only directly affects male violent prisoners aggressive behavior, but also indirectly affects male violent prisoners aggressive behavior through emotional recognition disorder.

Caracterización de la conducta agresiva y de variables psicosociales en una muestra de adolescentes de la ciudad de Bucaramanga y su área metropolitana / Characterization of aggressive behaviour and psychosocial variables in a sample of adolescents from the city of Bucaramanga and its metropolitan área

Resumen Introducción: La agresividad es una variable que se ha venido asociando a problemas sociales y clínicos; a su vez, se ha estimado un incremento de la misma denotando un riesgo mayor en población infanto-juvenil. Objetivo: Describir las características de la conducta agresiva y variables psicosociales asociadas (tipo de relaciones familiares y antecedentes personales), en una muestra de 351 adolescentes ente 12 y 17 años de edad de la ciudad de Bucaramanga y su área metropolitana. Método: Es una investigación cuantitativa de alcance descriptivo transversal. Se empleó un Cuestionario "Ad hoc" y el Cuestionario de Agresividad Premeditada e Impulsiva en Adolescentes (Andreu, 2010), los cuales se aplicaron de forma autoadministrada desde un muestreo no probabilístico. Los resultados se obtuvieron a través del programa estadístico SPSS, realizando un análisis estadístico de medidas de tendencia central y Chi cuadrado. Resultados: Se identificó que la agresividad es frecuente en los adolescentes, especialmente de tipo impulsiva (33 %), y predominando en las mujeres (premeditada= 25,4 %; impulsiva= 37,3 %). Los adolescentes con agresividad impulsiva alta se caracterizaban por menor edad (12 años= 7,7 %) y menor nivel académico (séptimo grado o menos= 14,8 %). De forma genérica, quienes tenían agresividad alta, tenían relación distante desde lo afectivo y físico con el padre, y antecedentes de haber tenido problemas con otros por ejercer la agresión. Conclusión: Los hallazgos comprueban la frecuencia de la agresividad en la adolescencia, y llevan a reflexionar sobre posibles cambios en los roles sociales sobre la expresión de las emociones. Es fundamental estudiar la relación de la agresividad con la impulsividad, la edad, la dinámica relacional con los padres, con el fin de brindar mayores aportes en el desarrollo de estrategias de prevención de la conducta disfuncional asociada a la agresividad.

Abstract Introduction: Aggression is a variable that has been associated with social and clinical problems; at the same time, an increase in it has been estimated, denoting a higher risk in the child-adolescent population. Objective: To describe the characteristics of aggressive behavior and associated psychosocial variables (type of family relationships and personal history), in a sample of 351 adolescents between 12 and 17 years of age from the city of Bucaramanga and its metropolitan area. Method: It is a quantitative investigation of transversal descriptive scope. An "Ad hoc" Questionnaire and the Premeditated and Impulsive Aggression Questionnaire in Adolescents (Andreu, 2010) were used, which were self-administered from a non-probabilistic sampling. The results were obtained through the SPSS statistical program, performing a statistical analysis of measures of central tendency and Chi square. Results: It was identified that aggressiveness is frequent in adolescents, especially of the impulsive type (33 %), and predominantly in women (premeditated = 25,4 %; impulsive = 37,3 %). Adolescents with high impulsive aggressiveness were characterized by younger age (12 years = 7,7 %) and lower academic level (seventh grade or less = 14,8 %). In a generic way, those who had high aggressiveness, had a distant emotional and physical relationship with the father, and a history of having had problems with others for exerting aggression. Conclusion: The findings verify the frequency of aggressiveness in adolescence, and lead to reflect on possible changes in social roles on the expression of emotions. It is essential to study the relationship of aggressiveness with impulsivity, age, and relationship dynamics with parents, in order to provide greater contributions in the development of strategies for the prevention of dysfunctional behavior associated with aggressiveness

A chain mediating model of emotion dysregulation and trait anger in the relationship between childhood abuse and aggressive behavior within the undergraduate students / 中华行为医学与脑科学杂志

Objective:To explore the chain mediating effect of emotion dysregulation and trait anger between childhood trauma and aggressive behavior in adolescents.Methods:A sample of 1 333 undergraduates were recruited to complete the questionnaires about childhood trauma, aggressive behavior, emotion dysregulation, trait anger.The SPSS 23. 0 and Mplus 8.3 software were used to analysis data and test intermediate effect.Results:The scores of childhood trauma, aggressive behavior, difficulties in emotion regulation and trait anger were (33.624±8.211), (53.995±12.307), (91.781±17.518), (23.352±5.477), respectively. Correlation analysis showed that childhood trauma, aggressive behavior, emotion dysregulation and trait anger were positively correlated with each other( r=0.209-0.614; all P<0.01). Mediation modeling analysis showed that childhood trauma had a significant direct effect on aggressive behavior. The direct effect value was 0.121, accounting for 35.8% of the total effect. The total indirect effect of childhood trauma on aggressive behavior was 0.217, accounting for 64.2% of the total effect. The mediating effect of emotion dysregulation as mediator between childhood trauma and aggressive behavior was 0.035, accounting for 10.4% of the total effect. The mediating effect of trait anger as mediator between childhood trauma and aggressive behavior was 0.108, accounting for 31.9% of the total effect. The chain mediating effect of emotion dysregulation and trait anger was 0.074, accounting for 21.9% of the total effect. Conclusion:Emotion dysregulation and trait anger exert a multiple mediating effect on the relationship between childhood trauma and aggressive behavior.

Mediating effect of coping styles on aggressive behaviors against bus drivers and their mental health status / 中国职业医学

OBJECTIVE: To explore the mediating effect of coping styles on aggressive behavior against bus drivers and their mental health status. METHODS: A total of 447 bus drivers were selected as the research objects using the method of judgment sampling. The aggressive behavior, mental health status and coping style of bus drivers were investigated using the Questionnaire of Aggressive Behaviors Against Bus Drivers, Symptom-Checklist 90 and Questionnaire of Simplified Coping Style Questionnaire. RESULTS: The median scores of aggressive behavior against bus drivers, positive coping style, negative coping style and mental health status were 50.0, 22.0, 10.0 and 125.0, respectively. Aggressive behavior against bus drivers and negative coping style were positively correlated with mental health status [Spearman correlation coefficient(r_S) were 0.27 and 0.42, respectively, P<0.01]. Positive coping style was not correlated with mental health status(r_S=-0.08, P>0.05). The total effect of aggressive behavior against bus drivers on their mental health status was 0.30. The mediating role of negative coping styles on aggressive behavior against bus drivers and their mental health status was 0.10, accounting for 33.1% of the total effect. CONCLUSION: Negative coping styles play a partial mediating role on the impact of aggressive behavior against bus drivers′ mental health status.

Relationship between aggressive behavior in patients with bipolar disorder and DRD4 gene polymorphism and personality characteristics / 上海交通大学学报（医学版）

Objective: To explore the relationship between aggressive behavior, dopamine receptor D4 (DRD4) exon III 48 bp variable number tandem repeat (VNTR) and personality characteristics in patients with bipolar disorder. Methods: From January 2015 to December 2018, 173 patients with bipolar disorder were selected from Shanghai Changning Mental Health Center, Shanghai Jing'an Mental Health Center, Shanghai Xuhui Mental Health Center, and Shanghai Jiading Central Hospital. According to the score of Modified Overt Aggression scale (MOAS), 173 patients were divided into aggressive behavior group (research group) and non-aggressive behavior group (control group). General survey and the temperament and personality questionnaire (Temperature and Character Inventory, TCI) were carried out, respectively. The polymorphism of DRD4 gene were genotyped by the polymerase chain reaction-restriction fragment length polymorphism method. Genetic equilibrium test of genotype Hardy-Weinberg and the difference of genotype frequency between the two groups were analyzed by using SHEsis software. The relationship between aggression behavior and DRD4 gene polymorphism and personality traits in bipolar disorder patients was analyzed by χ2 test and t test. Results: There was no significant difference in the general data between research group and control group (P>0.05). Six alleles and nine genotypes of DRD4 exon III 48 bp VNTR were detected. The most common alleles in the two groups were four repeat alleles. There were statistical differences in the frequency distribution of genotypes and alleles of DRD4 exon III 48 bp VNTR between the two groups (P=0.040, P=0.018). The scores of novelty seeking and harm avoidance in the research group were higher than those in the control group (P=0.026, P=0.000), while the scores of cooperativeness and self-directedness were lower than those in the control group (both P=0.000). Patients with long repeat alleles had significantly higher scores in novelty seeking and harm avoidance, and lower scores in cooperativeness, compared with patients with short repeat alleles (P=0.000, P=0.006, P=0.038). Conclusion: Aggressive behavior in patients with bipolar disorder may be associated with DRD4 exon III 48 bp VNTR. In bipolar disorder, patients with aggressive behavior have unique personality characteristics in impulsiving, novelty-seeking, exploring, being afraid of uncertainty, revengeful, behaving himself and so on. Patients with long repeat alleles have more significant personality abnormalities.

Sleep pattern, aggressive behavior and substance use among school students of Manipur: A cross-sectional study

Background: Adolescence is a vulnerable period of growth and development. This is the time when habits are inculcated which will carry forward to adult life. Sleeping patterns among adolescents have an impact on their overall health. Early substance use initiation is a serious concern because it is associated with significantly increased risks for developing substance use disorders. In general, aggressive behaviors progress from less to more severe over the course of adolescent development. Objectives: The objectives of this study are to determine the lifestyle behaviors of young adolescents focusing on sleep pattern, aggressive behavior, and substance use. Methods: A cross-sectional study was conducted among 739 students of Class VII and VIII in both government and private schools in Imphal West and Kangpokpi districts of Manipur between August 27 and September 25, 2017. A pretested, structured questionnaire was used, which included the modified version of Buss and Perry Aggression Questionnaire. The data were analyzed using the IBM SPSS software (IBM SPSS for Windows, Version 21.0. Armonk, NY, USA). Results: Only 56.2% of the students had adequate sleep. The proportion of adolescents using alcohol, tobacco, cigarettes, and Ganja was 4.6%, 9.5%, 5.7%, and 1.6%, respectively. Aggressive behavior was shown by 35.3%. Male students were getting more sleep (60.7%), were more aggressive (38.8%), and were using tobacco and cigarettes (82.4%) more than female students. Conclusions: Around two-fifth of the adolescents were not getting enough sleep. The association between aggressive behavior and substance use was found but needs further investigation for its temporal relationship.

Conceptuación y Medición de la Agresividad: Validación de una Escala / Conceptualization and Measurement of Aggressiveness: Validation of a Scale / Conceito e Medição da Agressividade: Validação de uma Escala

Resumen El objetivo de esta investigación fue construir una escala de agresividad confiable y culturalmente relevante para adultos mexicanos. Se elaboraron 96 reactivos en escala Likert a partir de indicadores obtenidos en un estudio preliminar y de planteamientos teóricos. Participaron voluntarios de la Ciudad de México. Se obtuvieron cinco factores que agrupan 25 reactivos que explican el 61.59 % de la varianza, 0=0.92. En otro estudio, se realizó un análisis factorial confirmatorio que mostró índices de ajuste adecuados. Posteriormente, se obtuvieron correlaciones entre la personalidad y la agresividad. Los resultados muestran que los factores extroversión, afabilidad, responsabilidad y apertura se asocian negativamente a la agresividad; mientras que el neuroticismo se asocia positivamente. Respecto a las diferencias por sexo, los resultados indican que los hombres muestran niveles más elevados de reactividad y las mujeres de frustración. Se concluye que la escala es un instrumento válido y confiable que permite reconocer diferencias entre los cinco grandes factores de personalidad, así como en hombres y mujeres.

Abstract The objective of this research project was to construct a reliable and culturally relevant scale to measure aggressiveness in Mexican adults. A 96-item Likert scale was designed, on the basis of indicators drawn from a preliminary study and of theoretical formulations. Participants were volunteers from Mexico City. Five factors were obtained that group together 25 items explaining 61.59 % of the variance, 0=0.92. In another study, a confirmatory factor analysis was performed, which showed adequate indexes of adjustment. Subsequently, correlations between personality and aggressiveness were obtained. Results show that the extroversion, affability, responsibility, and openness factors are negatively associated with aggressiveness, while neuroticism is positively associated. With respect to differences by sex, findings indicate that men show higher reactivity levels and women, higher frustration levels. The conclusion is that the scale is a valid and reliable instrument that makes it possible to identify differences among the five big personality traits, as well as between men and women.

Related factors of aggressive behavior among school aged children in Nanjing / 中国心理卫生杂志

Objective:To study the distribution and related factors of aggressive behavior among school aged children in Nanjing.Methods:Totally 4678 primary school students in Nanjing were sampled by cluster random sampling in this study.The General questionnaire and Achenbach's child Behavior Checklist were used to investi gate the general situation and aggressive behavior.Results:The rate of aggressive behavior of school-age children in Nanjing was 3.6 ％ (167/4678).Multivariate logistic regression analysis indicated that democratic parenting style [other parenting styles (OR =1.94,95％ CI =1.10-3.42),mixed parenting style(OR =1.96,95％ CI =1.35-2.85)],and genetic screening before birth (OR =0.71,95％ CI =0.52-0.99) were protective factors for children's aggressive behavior.The factor figures of aggressive behavior were positively correlated with that of oth er behavior problems in Pearson correlation analysis (r =0.52-0.80,Ps ＜0.01).Conclusion:About 3.6％ of the school aged children in Nanjing have aggressive behavior.It is more likely to have aggressive behaviors for children who is in other parenting styles except the democratic style and never have the genetic screening before birth.And children who with aggressive behavior may co-occur with other behavior problems.

Tumor odontogénico queratoquístico en seno maxilar: reporte de un caso clínico / Keratocystic odontogenic tumor in the maxillary sinus: report of a clinical case

El tumor odontogénico queratoquístico, es una patología que se encuentra asociada a la retención de un órgano dentario, en especial al tercer molar, es reconocido por su potencial destructivo y extenso, erosionando placas corticales que envuelven mucosa y tejidos blandos, la etiología del tumor odontogénico queratoquístico está probablemente relacionada con el desarrollo de la lámina dental (o restos de Serres) y con una mayor recidiva dentro de los tumores odontogénicos, siendo motivo de su reclasificación en el 2005 por la OMS. Se presenta casoclínico de un tumor odontogénico queratoquístico en el seno maxilarderecho, se exponen los métodos utilizados para la exploración clínica,radiológica y el tratamiento quirúrgico elegido.

The keratocystic odontogenic tumor is a condition associated withtooth retention, particularly of the third molar. It is recognized as beingpotentially highly destructive, by eroding cortical plates overlying theoral mucosa and soft tissues. The etiology of keratocystic odontogenictumor is probably related to the development of the dental lamina (orremains of Serres) and the recurrence rate is high compared to that ofother odontogenic tumors, the reason for their reclassifi cation by theWHO in 2005. We present a clinical case of a keratocystic odontogenictumor in the right maxillary sinus, including an explanation of themethods used for clinical and radiological examination, and the chosensurgical treatment.

Comportamiento prosocial y agresivo en niños: tratamiento conductual dirigido a padres y profesores / Prosocial and aggressive behavior in children: Treatment behavior for parents and teachers

Resumen El análisis conductual aplicado a través del entrenamiento a padres y profesores ha demostrado su efectividad para incrementar el comportamiento prosocial en niños que exhiben conductas agresivas; sin embargo, es escaso el trabajo de investigación que implique el efecto aditivo del tratamiento de ambos agentes. El objetivo del estudio fue conocer la efectividad de un programa de entrenamiento a padres y a profesores en 2 condiciones experimentales, para disminuir el comportamiento agresivo e incrementar el prosocial en alumnado de Educación Básica, en un estudio cuasiexperimental con diseño de inversión A-B-A. Participaron 3 docentes, 14 padres de familia y 94 alumnos, identificando a 14 que exhibieron comportamiento agresivo y mostraron déficit en comportamiento prosocial. Los programas de intervención empleados en el estudio se organizaron en 2 condiciones experimentales: la primera incluyó solo el entrenamiento a padres y la segunda incluyó el entrenamiento a padres más el entrenamiento a profesores en técnicas de modificación conductual. Los resultados demostraron que la intervención con 2 agentes de cambio obtuvo un mayor incremento en el comportamiento prosocial y una mayor disminución de comportamiento agresivo en el contexto familiar comparado con el grupo que recibió solo el entrenamiento a padres. También el tratamiento combinado demostró cambios significativos en el comportamiento de los niños en el contexto escolar.

Abstract Applied behavior analysis has demonstrated its effectiveness to increase prosocial behavior in children with aggressive behavior through parent and teacher training, however, research work is limited regard the additive effect of the treatment with both agents. The target of the study was to evaluate the effectiveness of an intervention program addressed to teachers and another addressed to parents in a quasi-experimental study with A-B-A design. Three teachers, 14 parents and 94 students participated, identifying14 who presented aggressive behavior and showed deficits in pro-social behavior. The intervention programs used in the study plus teacher training in behavior modification techniques. Results showed that the intervention with 2 agents was the most effective to increase prosocial behavior and decrease aggressive behavior in the family context compared with the group that received only parent training. Also the combined treatment showed significant changes in the school context.

Parenting violence modulates mediating effect of violent attitude between trait anger and aggressive behavior / 中华行为医学与脑科学杂志

Objective To explore the relationships among college students' trait anger,violent attitude and aggressive behavior.Methods A total of 991 college students were surveyed with the Trait Anger Scale,the Violent Attitude Questionnaire and the Aggression Questionnaire.Results (1)College students' scores on trait anger,violent attitude and aggressive scales were 17.99±3.94,3.52±2.20 and 70.12±14.67,respectively.(2) There were significant correlations among college students' trait anger,violent attitude and aggressive behavior(r=0.172-0.835,P<0.01).(3) Trait anger had a direct impact on aggressive behavior,as well as indirect effects through violent attitude.The direct effect of trait anger on aggressive behavior was 0.53,the indirect effect of violent attitude was 0.13,the total effect was 0.66,and the indirect effect was 20%.(4)The experience of parenting violence moderated the mediating effect of voilent attitude,and violent attitude moderated trait anger and aggression in those who didn't experience parenting violence(β=0.28,P<0.01),while the mediating effect was not significant in those who experienced parenting violence(β=-0.24,P=0.23,SIE=-0.166,P=0.28).Conclusion Violent attitude partially mediates trait anger and aggressive behavior,which is moderated by experienced parenting violence.

Effect of serotonin 1A receptor agonist on pathological aggressive behaviors and brain-derived and glial cell-derived neurotrophic factors in prefrontal cortex and hippocampus of puberty rats / 第二军医大学学报

Objective To explore the effect of serotonin 1A (5-HT1A) receptor agonist 8-OH-DPAT on pathological aggressive behavior, brain-derived neurotrophic factor (BDNF) and glial cell-derived neurotrophic factor (GDNF) in prefrontal cortex and hippocampus in pubertal rats. Methods Forty-two 21-day-old male SD rats were randomly divided into 6 groups:model group, normal group, model+8-OH-DPAT group, model+normal saline (NS) group, normal+8-OH-DPAT group and normal+NS group, with 7 rats in each group. The rats in the model, model+8-OH-DPAT and model+NS groups were given a series of early chronic stresses to establish the pathological aggressive animal model, and the other 3 groups were fed normally. Then the rats in the model+8-OH-DPAT and normal+8-OH-DPAT groups were injected intraperitoneally with 8-OH-DPAT (0.5 mg/kg), while the rats in the model+NS and normal groups were administered with 2 mL of NS. We determined the aggressive behaviors of the rats through resident-intruder test and detected the protein expressions of BDNF and GDNF in prefrontal cortex and hippocampus by Western blotting. Results (1) Compared with the normal group, the latency in the first attack in the model group was significantly shorter (P0.05). (2) The protein expressions of BDNF and GDNF in the prefrontal cortex and hippocampus in the model group were significantly lower than those in the normal group (P<0.01), but they were significantly decreased in the model+NS group compared with the normal+NS group (P<0.05, P<0.01) and were significantly increased in the model+8-OH-DPAT group compared with the model+NS group (P<0.05, P<0.01). Conclusion The expressions of BDNF and GDNF in the prefrontal cortex and hippocampus may be related to the pathological aggressive behaviors induced by early chronic stress in puberty rats. 5-HT1A receptor agonist can reduce the pathological aggressive behaviors induced by early chronic stress and increase the expressions of BDNF and GDNF in prefrontal cortex and hippocampus in puberty rats.

The relevancebetween genetic polymorphismof NR3C1andaggressive behavior in Yunnan Han population / 中国法医学杂志

Objective To study the correlation between the polymorphisms of NR3C1 gene and aggressive behavior in Yunnan Han population.Methods Five SNPs of the NR3C1 gene (rs6190,rs6191,rs6198,rs41423247 and rs56149945) were genotyped in 194 unrelated prisoners who committed violent-crimes and 301 healthy controls using improved Multiplex-ligase-detection reaction(iMLDR) method,and the data were statistically analyzed with the SPSS19.0soflware and PHASE2.1platform.Results Single locus analysis showed that the allelic distribution of rs6191and rs41423247did not show significant differencesbetween the control groupand the aggressive-behavior group as well as the robbery sub-group and intentional injury sub-group.However,significant difference was foundin the rs41423247 genotype distribution betweencontrol groupand robbery sub-group (p=0.048).In addition,there were no significant differences for the four haplotypes between the control group,the attack group,the robbery subgroup and the intentional injury subgroup.Conclusion These findings indicate that rs41423247 polymorphism of the NR3C1gene might play a role in susceptibility to aggressive behavior and rs6191 polymorphismmay not be correlated withaggressive behavior.

Mediating effect of trait angeron relationship between childhood psychological maltreatment and online aggressive behavior in college students / 中国心理卫生杂志

Objective:To explore the relationship among childhood psychological maltreatment,online aggressivebehavior and trait anger in college students.Methods:Totally 442 college students (226males,216 females,aged 16-25 years) were surveyed with the Psychological Maltreatment Scale (PMS),Adolescent Online Aggressive Behavior Scale (AOABS) and Trait Anger Scale (TAS).The bias-corrected percentile bootstrap method was used to analyze the mediating effect of trait anger between childhood psychological maltreatment and online aggressive behavior.Results:The scores of PMS,AOABS and TAS were positively correlated each other(r =0.44,0.37,0.48,Ps ＜0.01).The PMS scores had a significantly direct effect on the AOABS scores,its estimate was 0.27.The PMS scoreshad a significantly indirect effect on the AOABS scores through TAS scores(95％ CI:0.15-0.34).Conclusion:It suggests that the trait anger may be related to childhood psychological maltreatment and online aggressive behavior,and trait anger may play a partial mediating role between childhood psychological maltreatment and online aggressive behaviorin college students.

Comparison of gene frequencies of short tandem repeats loci on Y Chromosome between offenders with initiative-aggressive behavior and impulsive-aggressive behavior / 中华行为医学与脑科学杂志

Objective To explore the distributional differences of the gene frequencies of 22 short tandem repeats loci on Y Chromosome(Y?STRs) between offenders with Initiative?aggressive behavior and impulsive?aggressive behavior,and to probe into the genetic factors of initiative?aggressive behavior and im?pulsive?aggressive behavior. Methods Biological samples of 271 offenders with initiative?aggressive behav?ior and 271 offenders with impulsive?aggressive behavior were collected and PCR compound amplification was carried out with the aid of PowerPlex Y23 System. Then the PCR products were subjected to electrophoresis and gene detection with AB3500xL gene analysis system so as to calculate and compare the alleles and haplo?types of 22 Y?STRs gene frequency in the two groups. Results The distribution of allele frequency were sig?nificantly difference in locus DYS437(P=0.022) between two groups,not in the other 21 Y?STRs loci( all P>0.05) . Univarite analysis showed significant differences at allelle 14 in locus DYS437 between both groups ( initiative?aggressive behavior group:69. 37%;impulsive?aggressive behavior group:58. 67%; P=0. 009 ) . Conclusion Loci DYS437 may be associated with aggressive behavior. In the group of aggressive behavior, allelle 14 on locus DYS437 may be the susceptible factor of initiative?aggressive behavior and the resistant factor of impulsive?aggressive.

Psychometric Study of the Antisocial Behaviour Questionnaire (CC-A) in early adolescents from Tucumán, Argentina / Estudio psicométrico del cuestionario de conducta antisocial (cc-a) en adolescentes tempranos de tucumán, argentina

Resumen El comportamiento antisocial se refiere a una diversidad de actos que infringen las normas sociales y de convivencia. Su delimitación está dada tanto por la valoración social de la gravedad de los comportamientos como por su alejamiento a las pautas normativas de una sociedad. El objetivo de este trabajo fue analizar las propiedades psicométricas del cuestionario de Conducta Antisocial (CC-A) en adolescentes de Tucumán, Argentina. Se aplicó el CC-A y la Batería de Socialización BAS-3 a quinientos once adolescentes escolarizados de once y doce años. Se encontró una solución de tres factores que explicaban el 35 % de la varianza, congruente con la propuesta original. Los coeficientes Alpha de Cronbach fueron adecuados en Agresividad (.735), Aislamiento (.769) y Ansiedad/Retraimiento (.681), y se establecieron relaciones entre CC-A y BAS-3. Así mismo, se observaron correlaciones negativas entre Agresividad, Consideración con los demás y Autocontrol mientras que fueron positivas entre Aislamiento y Retraimiento. Posteriormente, se determinaron las categorías percentilares de esta versión (CC-A de ventiocho ítems); 18% de los adolescentes presentaban percentiles de riesgo en Agresividad mientras que un 20.9% lo hacía en Aislamiento. El estudio aporta datos con respecto a las propiedades psicométricas del instrumento en población local, indicando su sensibilidad para la evaluación del comportamiento antisocial.

Abstract Antisocial behavior refers to a diversity of actions, which infringe social norms, and rules of living together. This antisocial behavior is marked out both by a social appraisal of the severity of the conduct and by its distance from the norms of a society. The aim of this work was to analyze the psychometric properties of the Antisocial Behavior Questionnaire (CC-A) in adolescents from Tucumán, Argentina. The CC-A and the BAS-3 Socialization Scale were administered to 511 adolescents between 11 and 12 years old who are attending school. A three factors solution, which explains the 35% variance was found, which was consistent with the original proposal. Chronbach's Alpha coefficients were adequate in Aggressiveness (.735), Isolation (.769) and Anxiety/Withdrawal (.681). Connections between CC-A and BAS-3 were established. Negative correlations between Aggressiveness, Consideration for others and Self-control were found, whereas positive ones between Isolation and Withdrawal were established. Afterwards, percentile categories of this version (CC-A of 28 items) were determined; 18% adolescents showed risk percentile in Aggressiveness and 20.9% in Isolation. The study provides data concerning the psychometric properties of the instrument in the local population, indicating its sensitivity to assess antisocial behavior.

Personality and aggression: a contribution of the General Aggression Model / Personalidade e agressão: uma contribuição do Modelo Geral da Agressão

The aim of the study was to identify the direct and indirect existing relationship among personality traits on aggression of high school and undergraduate students from the city of João Pessoa, Brazil, using the General Aggression Model as the theoretical framework. The sample consisted of 218 students, of which 107 were high school students and 111 undergraduate students. The instruments used for data collection were as follows: Aggression Questionnaire, the Big Five Inventory and a Socio-Demographic Questionnaire. The main results showed direct effects of neuroticism (+), extraversion (+) and agreeableness (-) in physical aggression. On the other hand, indirect effects of neuroticism (+), opening (+) and agreeableness (-) in physical aggression, mediated by aggressive emotions have been found. These findings are discussed based on previous research and the General Aggression Model along with suggestions of research which have been conducted in an attempt to further knowledge in this area.

Este estudo objetivou conhecer a relação direta e indireta que há entre os traços de personalidade e a agressão de estudantes do ensino médio e superior da cidade de João Pessoa. Como aporte teórico, foi utilizado o Modelo Geral de Agressão. Contou-se com uma amostra de 218 estudantes, dos quais 107 eram alunos do ensino médio e 111, universitários. Os instrumentos utilizados para a coleta de dados foram os seguintes: o Questionário de Agressão, o Inventário dos Cinco Grandes Fatores de Personalidade e um Questionário Sócio-Demográfico. Os principais resultados mostraram efeitos diretos do neuroticismo (+), extroversão (+) e agradabilidade (-) na agressão física. Verificaram-se, por outro lado, efeitos indiretos do neuroticismo (+), abertura (+) e agradabilidade (-) na agressão física mediadas pelas emoções agressivas. Esses achados são discutidos com base em pesquisa prévia e no Modelo Geral da Agressão e sugestões de pesquisas as quais foram realizadas para se avançar nessa área.
