Age as a Differential Characteristic of Rapists, Pedophiles, and Sexual Sadists

Abstract

In this study, we investigated the role of age in three categories of 168 sex offenders, including 53 rapists, 62 pedophiles, and 53 sadists. On the basis of the match between requisites of completing each type of sexual offense, we hypothesized that rapists would be less represented in the older age group, whereas pedophilic and sexually sadistic offenders would show a more muted decline with age. This hypothesis was supported by the data, clearly a showing smaller number of rapists in the over 40 group relative to the number of pedophiles and sadists (p = 0.0009.) Further examination of the files eliminated the alternate explanation ascribing this pattern to lack of opportunity in older rapists because of incarceration. These results suggest that age over 40 may mitigate incidence of recidivism in rapists, but not in pedophiles or sexual sadists. Approximately one third of the sexual sadists had committed either first- or second-degree murder, whereas none of the nonsadistic rapists or pedophiles had these crimes on their records. The data further justify categorization of sex offenders into nonsadistic rapist, sadistic rapist, and pedophilic offenders in future research to enhance precision in delineating demographic characteristics and putative causal explanations for sexual offending.

Serial murder by children and adolescents

“…Additionally, they appeared for the most part to best fit into the ''Predatory'' category of juvenile sexual killers-the category with the assumed poorest prognosis-given their more conscious, controlled, psychopathic styles of killing (rather than fitting in the ''Explosive,'' ''Revenge,'' or ''Displaced Matricide'' categories; see Myers, 2002). Many authors believe sadistic murderers will continue to sexually assault and kill victims, and that the only effective ''treatment'' for this condition is preventive detention (Dickey, Nussbaum, Chevolleau, & Davidson, 2002;Douglas & Olshaker, 1995;Geberth & Turco, 1997;Volavka, 1999).…”

When is profiling possible? Offense planning and aggression as moderators in predicting offender age from victim age in stranger rape

“…In recent years, clinical forensic studies (e.g. Dickey, Nussbaum, Chevolleau, & Davidson, 2002) have also found psychological differences between offender groups, based on a linear victim-offender age relationship. For example, Kalichman (1991) found a linear relationship between victim age and offenders' psychological problems.…”

Tatcharakteristika, Rückfallrisiko und Rückfallprognose bei Sexualstraftätern vom Jugend- bis ins Seniorenalter

“…Neuere Studien belegen demnach, dass sexuelle Gewalttäter mit einer hö-heren Wahrscheinlichkeit antisoziale, Missbrauchstäter hingegen eher sexuell deviante Eigenschaften aufweisen (z.B. [2,5]) und dass vor allem Vergewaltiger größere Ähnlichkeiten mit anderen Straftätergruppen zeigen abb. 5 Einschlägige Rückfall-raten erneuter Sexualdelikte in den Risikogruppen des static-99 in der Gesamtgruppe und der Gruppe äl-terer Sexualstraftäter über 60 Jahre…”
