Bystander Effect

10.4K
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.

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...

Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Group Design

11.0K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Area of Science:

  • Public Health
  • Criminology
  • Sociology

Background:

  • The Campus Sexual Violence Elimination Act mandates bystander training for U.S. colleges.
  • The effectiveness of bystander intervention programs in preventing violent behavior remains understudied.
  • This research offers a multiyear evaluation of a campus-level bystander intervention's impact on interpersonal violence.

Purpose of the Study:

  • To evaluate the campus-level impact of the Green Dot bystander intervention on reducing interpersonal violence.
  • To assess the efficacy of bystander training in preventing violent behavior among college students.
  • To determine if the Green Dot program meets the requirements of the Campus Sexual Violence Elimination Act.

Main Methods:

  • A quasi-experimental design comparing one intervention campus with two comparison campuses.
  • Online surveys administered to first-year students from 2010-2013.
  • Multivariable logistic regression analysis to compare violence rates between intervention and comparison groups, adjusting for covariates.

Main Results:

  • Interpersonal violence victimization rates were 17% lower in the intervention group (46.4%) compared to the comparison group (55.7%).
  • Interpersonal violence perpetration rates were lower in the intervention group (25.5%) compared to the comparison group (32.2%).
  • Significant reductions in unwanted sexual victimization, sexual harassment, stalking, and psychological dating violence were observed in the intervention group.

Conclusions:

  • The Green Dot bystander intervention demonstrates efficacy in reducing interpersonal violence at the community level.
  • The program shows potential for meeting Campus Sexual Violence Elimination Act bystander training mandates.
  • Bystander intervention strategies can be effective in mitigating campus violence.
