Treatments tested in this trial
Friend-Based Motivational Interview
BehavioralThe intervention will use Motivational Interviewing's (MI) collaborative conversation style for strengthening commitment to change, to motivate and prepare women to work together to reduce Sexual Assault (SA) risk. This intervention will target ways that the friend dyad may support, encourage, and share responsibility with one another in protecting against SA. The Friend-based MI (FMI) will then use the responsibility and relationship of friends as a framework to foster collaborative efforts to increase readiness and decrease barriers to helping behavior. As part of this, the FMI will focus on the identification and implementation of skills friends can use to help one another prevent sexual assault. FMI will include a focused discussion of the ways drinking may impede helping efforts. Moreover, the FMI will encourage women to identify personal, specific strategies for reducing the effects of alcohol on helping.
Treatment as usual (TAU)
BehavioralThis 65-minute single-session stand-alone course is a supplemental component of the EverFi (Vector Solutions) Sexual Assault Prevention for Undergraduate Students prevention suite that is administered in an online didactic format. All participants (intervention and control) will have completed the basic course of the Sexual Assault Prevention for Undergraduate Students at matriculation, per university requirements. For the current study, the supplemental Healthy Relationships component will be administered only to participants assigned to the control condition. Healthy Relationships focuses on relationship skills, strategies for taking action in risky situations, and intervention skill practice.
Treatment groups
Trial outcomes
Primary outcomes
Alcohol-Involved Sexual Assault
Revised Sexual Experiences Survey (R-SES) will be used to assess each social occasion with the target friend in the prior 2 weeks. Each item will be coded 1 (yes) or 0 (no), based on whether it happened to the woman/friend on each occasion that the pair socialized together.
Change in Drinking
Using a grid-based average assessment measure based in the Daily Drinking Questionnaire, participants will report on alcohol consumption. Higher scores indicate greater alcohol consumption.
Secondary outcomes
Change in Readiness to Intervene
Participants will use an 11-point likert-type scale modeled after the Readiness Ruler to rate their readiness for intervening. Responses range from 0 (I never think about my and/or my friend's risk of being sexually assaulted) to 10 (I am actively and consistently taking steps to protect myself and/or my friends from sexual assault), with higher scores indicating a greater readiness to intervene.
Change in Peer-Directed Bystander Behaviors Scale for Strangers
We used a modified version of The Bystander Behaviors Scale for Strangers is a 44-item measure which includes 4 sub-scales (1) the identification of sexual assault risk situations, (2) accessing resources, (3) planning ahead for risk situations, and (4) safety behaviors in risk settings. Response option include (0) No I did not engage in this behavior, (1) Yes I did engage in this behavior, or (missing) I did not perceive an opportunity to engage in this behavior. A higher endorsement of "Yes" (higher score) engaging in the behaviors is considered to indicate a greater use of strategies to prevent sexual assault.
Changes to Assault Protective Strategies
The Friend-based Assault Protective Strategies Assessment uses 20 items to assess sexual assault preventive strategy use. Responses range from 1 (Not at all) to 4 (A lot), with higher scores indicating a greater use of strategies to prevent sexual assault.
Change to Barriers to Sexual Assault Bystander Intervention
The Barriers to Sexual Assault Bystander Intervention Scale is a 16-item measure to assess barriers to intervening. Responses range from 1 (Strongly disagree) to 7 (Strongly agree), with higher scores indicating greater perceived barriers to intervening.
