The authors studied offender, offense, and victim characteristics in a cohort of 111 adult female sex offenders comprising all female sex offenders known to the criminal justice authorities in the Netherlands between 1994 and 2005. In 77% of the cases, the female sex offenders had abused children; almost two thirds of the women had co-offended with a male co-offender. Their backgrounds are on average problematic with sexual abuse being prominent (31%); mental disorders were also prominent (59%). Using multiple correspondence analysis, the authors distinguished four prototypical offender types. They identified the young assaulter and the rapist who are relatively young solo offenders. Two prototypes, the psychologically disturbed co-offender and the passive mother, comprise older women. They mostly abused their own children together with their male/intimate partner. These prototypes partly overlap with previous typologies. The authors discuss implications for theory and treatment.

The current study investigates the offending trajectories of juvenile sex offenders (JSOs) across and beyond adolescence. In doing so, the study examines the number, the rate, and the shape of nonsexual and sexual offending trajectories in a sample of JSOs followed retrospectively and prospectively from late childhood to adulthood. Using semiparametric group-based modeling, the study reveals the presence of five distinctive nonsexual offending and two sexual offending trajectories: adolescent-limited and high-rate slow desisters. The study does not find strong evidence of synchronicity between nonsexual and sexual trajectories, suggesting that the current taxonomy of antisocial behaviors may offer a limited perspective on sex offender types. Furthermore, sexual trajectories do not differ much across sex offender types, suggesting that the findings might be generalized to child and peer abusers. The study findings offer supporting evidence for the presence of two distinct JSO types with important implications for theory, research, and interventions.

The current paper provides a narrative review of the literature on sexual abuse, involving children with Intellectual Disability (ID). The thirteen articles that were found and met our criteria vary in their definitions of sexual abuse and in how ID was determined. Still, they do paint a general picture concerning (1) the extent of sexual abuse, (2) the nature of the sexual abuse, and (3) the institutional reactions following sexual abuse of children with ID. Our findings confirm the greater vulnerability of children with ID to become involved in sexual abuse both as a victim and as a perpetrator, and we discuss ways to help strengthening prevention and intervention methods. Nevertheless, more research is needed, as it is still a rather unexplored topic, which is striking in light of the high vulnerability of this group.

The results were suggestive of greater need for psychological interventions in the child molester group, although in both groups substantial minorities had had experience of early childhood deprivation or abuse.
