NCT07218159 | Enrolling By Invitation

• 1 other identifier: REB# 23-063
• Study Type: interventional
• Target: 289
• Locations: 2 countries
• Sites: 5

Brief Summary

The goal of this study is to understand if the Internet-Delivered Enhanced Assess, Acknowledge, Act (IDEA3) sexual assault resistance program works to prevent intimate partner violence in undergraduate women. Participants who were in a prior trial by the study team (the IDEA3 parent trial) and joined in September 2024 or later will be invited to also join this study at the conclusion of the parent study. Participants in this study will fill out one additional survey. Researchers will compare intimate partner violence victimization between the control group and the intervention group.

Conditions

Intimate Partner Violence (IPV)

Outcome Measures

Primary Outcomes (1)

• Physical and psychological intimate partner violence

  The Composite Abuse Scale Revised-Short Form (CASR-SF) will be used to measure IPV. The scale will be administered as written (16 items), but two questions relating to sexual IPV are removed from the scale in analysis to avoid overlap with sexual assault as an outcome. Thus, the modified CASR-SF uses 14 questions to measure physical and psychological IPV. Participants indicate the frequency with which they experienced each item, from never (0) to daily (5) and are determined to have experienced IPV based on validated cutoffs. All occurrences of IPV in all new relationships since the participants' enrollment in the main IDEA3 trial will be recorded. If a participant had multiple relationships, they will be asked to indicate in which relationship(s) the IPV had occurred.

IDEA3 sexual assault resistance intervention

EXPERIMENTAL

IDEA3 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.

Behavioral: IDEA3 Sexual Assault Resistance Intervention

ACTIVE COMPARATOR

Randomized participants who do not receive the intervention will receive one 60-minute session consisting of an internet delivered (Zoom) consent workshop.

Interventions

IDEA3 Sexual Assault Resistance Intervention BEHAVIORAL

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.

IDEA3 sexual assault resistance intervention

Consent workshop BEHAVIORAL

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.
