Looking forward in Records of Young Adults Convicted of Sexual Homicide, Rape, or Molestation as Youth: Risks for Reoffending

Abstract

To assess the risks predicting reoffense, 223 Rapists (M age = 14.2 yr., SD = 1.5; 25 girls, 198 boys) were matched with 223 Nonviolent Delinquents; risks were analyzed using logistic regression. The one predictor was prior court contacts (OR = 1.55e+12; AUC = .99, 95% CI = .98-.99). 223 Molesters were similarly matched with 223 Nonviolent Delinquents; this comparison yielded three predictors: previous court contacts (OR = 4.55e+23), poorer executive function (OR = 2.01), and lower social maturity (OR = .97; AUC = .98, 95% CI = .97-.99). Records for all cases (now M age = 24.2 yr., SD = 1.4) were reviewed forward 10 years and youth were classified into groups: Sexual Homicidal (1%, n = 7), Delinquent Rapists Later Adult Rapists (11%, n = 73), Delinquent Rapists (21%, n = 144), Delinquent Molesters Later Adult Molesters (10%, n = 69), Delinquent Molesters (23%, n = 153), Nonviolent Delinquent Later Nonviolent Adult Criminals (7%, n = 45), and Nonviolent Delinquents (27%, n = 178). Comparison of Sexual Homicidal cases (n = 7) with their matched Controls (n = 7) yielded one predictor, poorer executive function (AUC = .89, 95% CI = .71-.93). When Sexual Homicidal cases were matched with Nonviolent Delinquents, predictors were low social maturity and prior court contacts (AUC = .81, 95% CI = .64-.93).

Sex-Role Orientation and Attachment Styles of Sex Offenders

“…there were also recent studies on young adults convicted of sexual offenses such as sexual homicide, rape, or molestation (see Busch, et al 2009). The results in this study indicated poor executive functioning was associated with poorer outcome, although low social maturity also significantly predicted sexual homicide cases.…”

An Evaluation of Nonassaultive, Assaultive, and Sexually Assaultive Adolescents at Pretrial Sentencing: A Comparison on Cognition, Personality, Aggression, and Criminal Sentiments

“…Research by Busch, Zagar, Grove, Hughes, Arbit, Bussell, et al (2009) has shown that young offenders who commit sexual assaults have poorer executive function and low social maturity. This finding is in line with our research.…”

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

“…Note. From 4 ground breaking studies on 181 abused children later homicidal teens with 181 controls , 127 homicidal youth with 127 (Zagar, Busch, Grove, Hughes, & Arbit, 2009d), 450 assaulting teens later homicidal adults with controls (Zagar, Busch, Grove, & Arbit, 2009e), and 646 sex offending (223 rapists, 223 molesters) teens later sexual homicidal adults with 223 controls (Busch, Zagar, Grove, Hughes, Arbit, Bussell, & Bartikowski, 2009) The first beta testing was 236 individuals described above with male and female, adults and adolescents, working 120 job categories. A sample of 56 male and female adults (n=38) and teens (n=18) with the Mage =35.6 and 15.4 respectively were given the QT, BSS, MMPI-2 or MMPI-A, Raven, and SP.…”

“…Also these groups were studied: (c) n=48 randomly selected from 450 assaulting teens later homicidal adults with 450 controls (Zagar, Busch, Grove, & Arbit, 2009e), and (d) n=48 randomly selected from 646 sex offending (223 rapists, 223 molesters, 223 nonviolent controls) youth later sexual homicidal adults with 223 controls (Busch, Zagar, Grove, Hughes, Arbit, Bussell, & Bartikowski, 2009). …”

“…In the remaining fourth and fifth study, there were: (d) assaulting youth later homicidal adults, Mage=14.0 years (Zagar, Busch, Grove, & Arbit, 2009e); and (e) sex offending youth later sexual homicidal adults, Mage=14.2 years (Busch, Zagar, Grove, Hughes, Arbit, Bussell, & Bartikowski, 2009). Among these 2,722, there were 234 homicidal with a range (R)=10 to 17 years (Zagar & Grove, 2010).…”
