About

The goal of this experimental study is to examine the effect of alcohol, gender, and bystander attitudes on bystander barriers and sexual violence intervention among young adult men and women (age 21-20). The main questions it aims to answer are:

• Does alcohol intoxication and gender influence bystander barriers and sexual violence intervention?
• Does alcohol intoxication have a greater impact on bystander barriers and sexual violence intervention among men, compared to women?
• Does alcohol intoxication have a greater impact on bystander barriers and sexual violence intervention among those with higher, compared to lower, prosocial bystander attitudes?

Participants will be randomly assigned to one of two beverage conditions (alcohol or control beverage) and those assigned to alcohol will complete the study on either the ascending or descending alcohol limb. Participants will project themselves into a heat-of-the moment, risky sexual violence scenario that will assess bystander barriers and behavioral intentions. Researchers will compare those assigned to the alcohol and control beverage condition and men/women to see if this impacts bystander barriers and sexual violence intervention.

192 participants in 2 patient groups

Alcohol Intoxication

Experimental group

Description:

Participant will receive alcohol, the dose of which will be administered to result in a breath alcohol concentration of .08%.

Treatment:

Behavioral: Alcohol Intoxication- Ascending Limb

Behavioral: Alcohol Intoxication- Descending Limb

No-Alcohol Control

Active Comparator group

Description:

Participant will receive a no alcohol control beverage, therefore their breath alcohol concentration will be .00%.

Treatment:

Behavioral: No Alcohol Control
