Maximum likelihood exploratory factor analyses with oblique rotation were performed on AAS, BIS/BAS, reactive aggression and proactive power scales as well as computation of Cronbach's alpha and McDonald's omega. Tests for normality and homogeneity of variance were acceptable. Factor analyses of AAS and the proactive/reactive aggression scales suggested a hierarchical structure comprising a single higher-order angry aggression (AA) factor and four and two lower-order factors, respectively. Moreover, results suggested one BIS factor and a single higher-order BAS factor with three lower-order factors related to drive, fun-seeking and reward responsiveness. To compare scores of antisocial youths with controls, t-tests on the mean scale scores were computed. Results confirmed that antisocial youths were different from controls on the above-mentioned scales. Consistent with the idea that anger is associated with approach motivation, AAS scores correlated with behavioral activation, but only explosive/reactive and vengeful/ruminative AA correlated with behavioral inhibition. Results generally validated the quadruple typology of aggression and violence proposed by Howard (2009).

Study 1 demonstrates that experiencing virtual aggression from a victim’s perspective can impair players’ investments in a subsequent common goods dilemma situation. This effect is mediated by reduced expectations of trust in the cooperativeness of interaction partners. In Study 2 the same effect was replicated by using a different cooperation task and by investigating the moderating role of justice sensitivity from a victim’s perspective as a dispositional factor. Participants transferred less money to an unknown partner in a trust game after the exposure to aggressive non player characters in a video game. This effect was stronger for people high in victim sensitivity. Results of both studies can be interpreted in line with the sensitivity to mean intentions model and add to the body of research on violent media effects.

Intimate Partner Violence Perpetration and Problem Drinking Among College Students: The Roles of Expectancies and Subjective Evaluations of Alcohol Aggression

alcohol aggression expectancies and subjective evaluations of alcohol’s effects on aggression in intimate partner violence (IPV) perpetration among college students. We were interested in determining the extent to which these relationships differed across gender. Method: A total of
780 (57.3% female) incoming heavy drinking college freshmen who were between the ages of 18 and 25 years completed self-reported measures of IPV perpetration, alcohol use and problems, and alcohol aggression expectancies and subjective evaluations of those expectancies as part of the baseline assessment for a larger social norms alcohol intervention study. Analyses evaluated the effect of alcohol aggression expectancies and subjective evaluations of those expectancies on IPV perpetration. Results: Results indicated that problem drinking was positively associated with IPV perpetration for those who were lower (β =.32, p < .001) versus those who were higher (β = .07, p = NS) in alcohol
aggression expectancies. Among men, there was a significantly stronger relationship between problem drinking and IPV perpetration among  those who evaluated alcohol’s effects on aggression more favorably (β = .41, p < .001) versus less favorably (β = .11, p = NS). Among women,
there was not a significantly stronger relationship between problem drinking and IPV perpetration at less favorable (β = .17, p < .05) versus more favorable (β = .11, p < .06) evaluations of alcohol’s effects on aggression. Conclusions: Findings suggest that, in understanding IPV perpetration, it may not be sufficient to evaluate expected alcohol effects
without also including whether those effects are viewed as good or bad. Findings also suggest that the relationship between alcohol problems and IPV perpetration may be stronger and more straightforward for men than for women. (J. Stud. Alcohol Drugs 68: 706-713, 2007)

De entre estas perspectivas, algunas de las que han ejercido una mayor influencia han sido la de Dollard y sus colaboradores (1939) con su formulación original de la hipótesis frustración-agresión, la posterior ampliación y reformulación de la hipótesis F-A por parte de Leonard Berkowitz (Berkowitz, 1962, 1969), y la aplicación al estudio de la agresión de la Teoría del Aprendizaje Social desarrollada por Albert Bandura (Bandura, 1973, 1975).
En los últimos años, sin embargo, han ido apareciendo una serie de autores tales como Jorge Da Gloria, Richard DeRidder, Amélie Mummendey y James Tedeschi, que presentan la característica común de oposición a las teorías clásicas predominantes en el estudio de la agresión y, por derivación, a los métodos de estudio normalmente utilizados por los representantes de dichas teorías. Una característica común de estas nuevas formulaciones consiste en el énfasis puesto en la necesidad de una nueva definición del concepto de agresión que amplíe las definiciones normalmente utilizadas por los estudiosos del tema.

Method:  Empirical articles and reports with primary data pertaining to violence and aggression within adult psychiatric in-patient settings were retrieved. For each study, prospective antecedent data were extracted. The extracted antecedent data were thematically analysed, and all higher-level themes were meta-analysed using rate data. Results:  Seventy-one studies met the inclusion criteria, from which 59 distinct antecedent themes were identified and organised into nine higher-level themes. The higher-level antecedent theme 'staff-patient interaction' was the most frequent type of antecedent overall, precipitating an estimated 39% of all violent/aggressive incidents. An examination of the staff-patient interaction themes revealed that limiting patients freedoms, by either placing some sort of restriction or denying a patient request, was the most frequent precursor of incidents, accounting for an estimated 25% of all antecedents. The higher-level themes 'patient behavioural cues' and 'no clear cause' also produced other large estimates and were attributed to 38% and 33% of incidents overall. Conclusion:  This review underscores the influence that staff have in making in-patient psychiatric wards safe and efficacious environments.

and psychodrama decrease adolescent aggression. Th is is a quasi-experimental, pre-post
and follow up study with two experiments and one control group. Th e Aggression Scale
(Buss & Warren, 2000) adapted to Turkish by Can (2002) was administered as a pretest
to 9th grade students of Nezihe Yalvaç Anatolian Hotel and Tourism Vocational High
School in Adana. After the administration and assessment of the scale, 36 students who
had the highest aggression levels were selected and were randomly divided into three groups.
Th e experimental and control groups each included 12 students. Cognitive behavioral
techniques were applied to the first experimental group in 10 sessions, psychodrama
techniques were applied to the second experimental group in 14 sessions. No application
has been done to the control group. After the groups ended, the Aggression Scale was readministered
to all groups as a post test. 16 weeks after ending the groups, the scale was
administered one mor time to the experimental groups as a follow up test. Findings were
analyzed with ANCOVA and t test for dependent samples. Findings have showed that
cognitive-behavioral approach was eff ective in decreasing aggression scores, except verbal
aggression and psychodrama approach was eff ective in decreasing all aggression scores
except verbal physical aggression. ANCOVA analyses showed that cognitive-behavioral
approach was more eff ective in decreasing total aggression, physical aggression, and anger
than psychodrama. Follow up test results showed that the eff ects of group practices on
both experimental groups were lasting even 16 weeks later.
