Among the skills needed to guide preventive policies, the highlights are risk and protective factors for violent behavior. This study aims to contribute, from the psychiatric perspective, in exploring factors influencing the behavior of homicidal adolescents. We studied a group of cases (n = 15) of young killers and a control group (n = 35) of juveniles who committed other crimes (simple or qualified theft or rape), all of them institutionalized by court order in La Plata city, Buenos Aires, Argentina. In both groups were evaluated sociodemographic, criminological and psychosocial characteristics through ad hoc questionnaire, as well as psychiatric clinical variables through the MINI (Mini International Neuropsychiatric Interview). The results showed that the multiple factors studied were not significantly associated with the condition of being young murderer. The findings aim to sustain that, in this vulnerable population of youth, homicidal behavior depends more on the circumstances than of personal peculiarities. The authors suggest that preventive actions in adolescents with these risk factors could have an effect on criminal behavior in general, as in homicidal behavior in particular.

This research is aimed to the assessment of the reliability and aspects of the validity of the Argentinean version of the Hare Psychopathy Checklist: Youth Version. Thus, thirty institutionalized juvenile offenders were simultaneously assessed by two raters who produced independent and a consensus scores. The raters used information from the same multiple sources of information. The results support that the Argentinian version of the scale is a reliable, homogeneous instrument with high internal consistence. The Intraclass Correlation Coefficient for the total score was .98 and the Cronbach's Alpha Coefficient was 0.96. Findings also support concurrent and convergent validity of the scale using correlation measures with other criteria and measures relevant to the construct, such as the score of non-violent offenses (r = 0.55; p= 0.002), the score of violent-offenses (r = 0.48; p = 0.008); Impulsivity scale score (r = 0.44; p = 0.02) and the count of types of conduct problems (r = .65; p < 0,001).

Con respecto a este último tipo de violencia (el homicidio) la hipótesis a verificar en este trabajo, plantea que sobre la población integrada por delincuentes juveniles homicidas han interactuado factores de riesgo particulares que los distinguen del resto. El objetivo de la presente Tesis fue determinar la relevancia de factores de riesgo relacionados con el hecho de cometer homicidio en adolescentes infractores de la ley penal, internados en centros de la ciudad de La Plata, comparados con un grupo control de jóvenes que cometieron otros tipos de delitos internados en los mismos centros.

The sample consisted of 195 young men (mean: 16.8 years) imprisoned in reformatory institutions of the Province of Buenos Aires, Argentina, as they were convicted of murder (n=130), repeated murder (n=15), or attempted murder (n=50). Self and hetero-informed instruments, and professional assessment scales were used, namely: the Consideration of Future Consequences Scale (CFC); the Psychosocial Maturity Inventory (PSM); the Weinberg Adjustment Inventory (WAI); the Resistance to Peer Influence Questionnaire (RPIQ); the Psychopathy Checklist: Youth Version (PCL:YV); the Inventory of Callou...

Asimismo, destacaron la necesidad de disponer de instrumentos que permitan evaluar las vulnerabilidades y características sobre las que se pueda intervenir a los efectos de prevenir la persistencia en trayectorias delictuales. Con la meta de contribuir a completar esa información faltante se diseñó una amplia sistemática de evaluación con obtención de información sistematizada de las dimensiones biológica, psicológica y social. En este informe se describen aspectos de las dimensiones psicológica y social.

In this study, we have analyzed several psychological and social factors that could be theoretically related to juvenile homicidal behavior. Our case-control study included young ( M = 16.8 years) males institutionalized in the Province of Buenos Aires, Argentina, under judicial order for crime. Out of 195 cases, 130 had committed homicide, 15 had repeated homicide, and 50 had attempted homicide. The control group comprised 305 young males who had committed other types of crimes. Self-reported and informant-reported instruments and professional assessment were used: Consideration of Future Consequences (CFC) Scale, Weinberger Adjustment Inventory (WAI), Resistance to Peer Influence (RPI), Psychopathy Checklist–Youth Version (PCL-YV), and Inventory of Callous Unemotional ...
