Summary
Multiple perpetrator sexual assaults (MPSA) disproportionately affect younger, non-White victims and involve stranger perpetrators. MPSA cases often feature completed and multiple rapes, with distinct victim and perpetrator characteristics compared to single perpetrator sexual assaults (SPSA).
Area of Science:
- Criminology
- Forensic Psychology
- Victimology
Background:
- Limited research exists on the distinct characteristics of multiple perpetrator sexual assault (MPSA).
- Understanding MPSA is crucial for victim support and perpetrator profiling.
- Previous studies have not comprehensively compared MPSA with single perpetrator sexual assault (SPSA).
Purpose of the Study:
- To identify unique demographic and assault-related features of MPSA.
- To compare MPSA cases with SPSA cases.
- To differentiate characteristics of MPSA victims, perpetrators, and assault types.
Main Methods:
- Comparative analysis of 135 MPSA cases and 139 SPSA cases.
- Data collected from the Haven sexual assault referral centre over a 4-year period.
- Examination of victim demographics, perpetrator details, and assault specifics.
Main Results:
- MPSA victims were younger, less likely to be White, reported more self-harm, and sustained more injuries than SPSA victims.
- MPSA perpetrators were younger, less likely to be White, and more often strangers to the victim compared to SPSA perpetrators.
- MPSA involved more completed and multiple rapes, with perpetrators meeting victims outside before assaulting them in non-victim residences.
Conclusions:
- MPSA exhibits distinct victim, perpetrator, and assault pattern characteristics compared to SPSA.
- Findings contribute to the limited but growing evidence base on MPSA.
- This research aids in understanding the nuances of sexual assault involving multiple offenders.

02:04Bullying
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is bullying.

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.
