Peer approval of sexual aggression influences male students' attitudes, which in turn predict their sexually aggressive behavior. This highlights potential targets for sexual aggression prevention programs.
Area of Science:
- Psychology
- Criminology
- Sociology
Background:
- Sexual aggression remains a significant issue among male undergraduate students.
- Understanding the psychological and social factors influencing sexual aggression is crucial for effective prevention.
Purpose of the Study:
- To investigate the mediating role of evaluative attitudes toward sexual aggression.
- To examine the relationship between injunctive norms and self-reported sexual aggression.
- To explore these dynamics in a sample of male undergraduate students.
Main Methods:
- Survey administered to 200 male undergraduate students.
- Assessed history of sexual aggression and likelihood of future engagement.
- Tested mediation models linking injunctive norms, evaluative attitudes, and sexual aggression.
Main Results:
- Positive evaluative attitudes toward sexual aggression mediated the link between peer approval (injunctive norms) and both past and future sexual aggression.
- Approximately 25% of participants reported past sexual aggression.
Conclusions:
- Evaluative attitudes are a key factor explaining how peer norms influence sexual aggression.
- Findings support existing theories of criminal behavior and sexual offending.
- Suggests that prevention programs targeting norms and attitudes may reduce sexual aggression.
