Summary of Studies of Abused Infants and Children Later Homicidal, and Homicidal, Assaulting later Homicidal, and Sexual Homicidal Youth and Adults

Abstract

To study the risks of abuse, violence, and homicide, 5 studies of groups at risk for violence are summarized. 192 Abused Infants, 181 Abused Children, 127 Homicidal Youth, 425 Assaulters, 223 Rapists, and 223 Molesters were randomly selected and tracked in court, probation, medical, and school records, then compared with carefully matched groups of Controls and (in older groups) Nonviolent Delinquents. In adolescence or adulthood, these groups were classified into Later Homicidal (N=234), Later Violent or Nonviolent Delinquent, and Later Nondelinquent subgroups for more detailed comparisons. Shao's bootstrapped logistic regressions were applied to identify risks for commission of homicide. Significant predictors for all homicidal cases in these samples were number of court contacts, poorer executive function, lower social maturity, alcohol abuse, and weapon possession. Predictors for the 373 Abused cases (Infants and Children) were court contacts, injury, burn, poisoning, fetal substance exposure, and parental alcohol abuse. Predictors for the 871 Violent Delinquent cases (Assaulters, Rapists, Molesters) were court contacts, poorer executive function, and lower social maturity. Accuracies of prediction from the regressions ranged from 81% for homicidal sex offenders to 87 to 99% for other homicidal groups.

Finding High Risk Persons with Internet Tests to Manage Risk—A Literature Review with Policy Implications to Avoid Violent Tragedies, Save Lives and Money

“…Analyses comparing this sample with the demographics of the E.U. and U.S. populations are consistent with the suggestion that the cross-validated and replicated risks for violence, homicide, and pedophilia are generalizable to those broad areas (Zagar, Busch, Grove, & Hughes, 2009a). …”

“…Fourth, the first ever historical demonstration of targeting at-risk youth and diverting them from crime is the U.S.D.O.J.-sponsored Chicago from 2009 to 2012 programs (Zagar, Busch, & Hughes, 2009a; and the 2012 to 2015 Chicago Public Safety Fund Programs saving of 324 lives and $2,005,848,548 (Saulny, 2009;Shelton & Banchero, 2009;Ihejirika, 2014;Yaccino, 2014;City of Chicago, 2014;Kapos, 2014).…”

Relationship between Impulsiveness and Deviant Behavior among Adolescents in the Classroom: Age and Sex Differences

“…Deviant adolescents present personal characteristics and behaviors that may herald deviant and even criminal behavior in the future. Carroll, Houghton, durkin, and Hattie (2009) and Zagar, busch, grove, and Hughes (2009) reported that personality variables, and specifically impulsiveness, were linked with mild to severe deviant behavior. the aim of this study is to analyze the relationship between deviant behavior and impulsiveness among adolescents, taking into account their sociodemographic characteristics (e.g., age and sex).…”

An examination of the quality of psychiatric court reports for juvenile perpetrators of homicide

“…Previous research has shown that a number of social, behavioural and psychological characteristics are important risk factors for homicide among juvenile offenders (Heide, 2003;Rodway et al, 2011;Zagar, Busch, Grove, & Hughes, 2009b;Zagar, Busch, Grove, Hughes, & Arbit, 2009a). Many of these factors are brought to the attention of the court in the form of psychiatric or psychological reports commissioned to establish the most appropriate criminal justice outcome for juvenile offenders.…”
