Brief Summary
The goal of this randomized trial is to test whether the Internet-Delivered Enhanced Assess, Acknowledge, Act (IDEA3) sexual assault resistance education intervention reduces sexual violence victimization in undergraduate women. Participants in the intervention group will be asked to attend four three-hour group sessions of a sexual assault resistance program called IDEA3 with a partner, as well as fill out a number of surveys. Participants in the control group will be asked to attend a one-hour consent workshop with a partner and fill out surveys. Researchers will compare sexual assault victimization between the groups in the one year following the intervention.

Outcome Measures
Primary Outcomes (1)
Completed rape
The Sexual Experiences Survey Short Form Victimization (SES-SFV) will be used to measure the primary sexual assault outcomes. Completed rape will have occurred when a participant indicates she has had at least one experience of threatened, forced, or drugged completed (not attempted) sexual activity (oral, anal, or vaginal intercourse - answered 'once' or more to any of 9 questions (2c, 2d, 2e, 3c, 3d, 3e, 4c, 4d, or 4e) in the period between the baseline measurement and the 12-month survey measurement.
Baseline, 1-week post-intervention, 6-months and 12-months after randomization

Self-defense self-efficacy
Baseline, 1-week post-intervention, 6-months and 12-months after randomization
Perception of personal risk
Baseline, 1-week post-intervention, 6-months and 12-months after randomization
Detection of risk cues

Study Arms (2)
IDEA3 sexual assault resistance intervention
EXPERIMENTALIDEA3 curriculum will be delivered by pairs of trained facilitators over Zoom to reach up to 8 pairs of female-identified university students in four, 3-hour units. The four units will be spread over two to four weeks' time.
Consent workshop
ACTIVE COMPARATORRandomized participants who do not receive the intervention will receive one 60-minute session consisting of an internet delivered (Zoom) consent workshop.
Interventions
Internet-delivered EAAA (IDEA3), adapted from an in-person sexual assault resistance education intervention: Enhanced Assess, Acknowledge, Act (EAAA) intervention that was found in a randomized trial to reduce sexual assault victimization by about 50% at follow-up. IDEA3 designed for female identifying university students and focuses on resisting sexual assault committed by males in 4, 3-hour units: 1-ASSESS builds ability to detect risk with male acquaintances and develop risk reduction strategies. 2-ACKNOWLEDGE explores overcoming emotional barriers preventing women from acknowledging risk and employing effective resistance strategies with males. 3-ACT shows effectiveness of resistance strategies and teaches verbal and physical self-defense in common situations. 4-RELATIONSHIPS \& SEXUALITY adapts the Our Whole Lives curriculum to increase women's comfort in talking about sex/sexuality and identify sexual values/desires.
Participant pairs assigned to the control arm will receive a 60-minute session consisting of a 60-min interactive, virtual consent workshop. The workshop will include information on a) what consent is, including the idea that consent is about bodily autonomy and applies to interactions beyond sex, b) how to give and ask for consent, and c) examples of what it looks like to ask for and give/not give consent. This presentation will be given by a well-trained Research Assistant.
