Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Sexual violence (SV) perpetrated by dating partners and male acquaintances is common among adolescent girls in high school. Girls and young women who experience SV are likely to encounter negative mental and physical health consequences as well as lowered academic performance. While educational interventions to address the problem of SV are numerous, when evaluated, few show any capacity to reduce sexual violence victimization or perpetration. The Enhanced Assess, Acknowledge, Act (EAAA) sexual assault resistance program for female university students (ages 17-24) is a rare exception; in a rigorous trial, EAAA reduced attempted and completed rape by 50% in the following year. The current randomized controlled trial (RCT) will test whether a version of EAAA that has been adapted for younger girls (age 14-18) who have not graduated high school (called the Adolescent Enhanced Assess, Acknowledge, Act \[A-EAAA\]) will result in similar benefits within a 6-month follow-up. The current RCT will be conducted across three sites in Ontario, Canada.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Sexual violence (SV), which occurs along a continuum from unwanted sexual contact to rape, is common among adolescent girls and young women: research suggests 1 in 7 teen girls experiences SV. Perpetrators of SV are overwhelmingly male; however, the programs that exist to address boys'/men's perpetration are not sufficiently effective nor are they widely available. Other approaches to sexual assault prevention for adolescents, such as bystander programs, have not been shown to reduce sexual violence victimization or perpetration. Given the numerous negative consequences associated with SV, developing effective SV prevention and resistance programs targeting teens is critical for reducing victimization and improving health outcomes for adolescent girls. The Enhanced Assess, Acknowledge, Act (EAAA) sexual assault resistance program has been shown to substantially reduce rates of SV (50% for rape and attempted rape) in young women attending university (ages 17-24), but since it was designed for university students in a different developmental stage, an evidence-based adaptation was necessary. The purpose of the current study is to test the efficacy of the newly adapted Adolescent Enhanced Assess, Acknowledge, Act (A-EAAA) program in reducing sexual violence victimization among adolescent girls within 6-months of trial entry. We will continue to follow participants for one-year to evaluate whether changes in tertiary outcomes (e.g., mediators) are maintained to 12-months. A-EAAA is a 12-hour psychoeducational intervention that provides information, skills, and practice aimed at a) decreasing the time needed for girls to assess sexually coercive situations as dangerous and to take action, b) reducing emotional obstacles to taking action, c) increasing the use of the most effective methods of verbal and physical self-defense, and d) identifying sexual and relationship values and boundaries and reinforcing the right to defend them.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Approximately 900 self-identified girls/young women age 14-18 (who have not already graduated high school) will be recruited from 3 communities in Ontario over two years. Participants will be randomly assigned to either receive the A-EAAA program immediately (treatment group) or 6 months later (waitlist control group). Control group participants will attend a brief 'usual care' session providing them with basic information on SV and consent in parallel with the treatment group's first session. All participants will complete surveys at 4 timepoints: baseline, 1-week post-intervention (control group matched to treatment group timing), and 6 and 12 months after baseline. The control group will take the A-EAAA program following the 6-month post-survey and complete one additional survey, 1-week after their final program session.
Primary Study Purpose

PREVENTION

Blinding Strategy

NONE

All participants are blind to allocation at baseline assessment. Randomization occurs after in-person survey completion and is initially masked (using colour coded room assignments). Allocation is revealed to participants by intervention staff once they arrive at their assigned intervention room. All data analysis is done by a Co-I who has no contact with participants.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

A-EAAA (Adolescent Enhanced Assess, Acknowledge, Act) immediately

Adolescent adaptation of EAAA sexual assault resistance education (4, 3-hr sessions) begun immediately after baseline randomization

Group Type EXPERIMENTAL

A-EAAA Sexual Assault Resistance Education Program immediately

Intervention Type BEHAVIORAL

Adapted from the EAAA program created for university women, A-EAAA is designed for teen girls of all sexual identities and experience levels. It focuses on resisting sexual assault (SA) committed by male acquaintances with 4, 3-hour units: Unit 1(Assess) strengthens girls' ability to detect risk in contexts involving male acquaintances and helps develop strategies to reduce it. Unit 2(Acknowledge) helps girls explore ways to overcome their own emotional barriers preventing them from acknowledging risk and employing effective resistance strategies with males they know. Unit 3(Act) provides evidence on effectiveness of various resistance strategies and teaches verbal and physical self-defense focused on common acquaintance SA situations. Unit 4 (Relationships\&Sexuality) is an adaptation of Our Whole Lives curriculum and aims to increase girls' comfort talking about sex/sexuality and identify their sexual values/desires and explore possibilities for sexual practices beyond intercourse.

Waitlist Control

Usual care 30-min session (brief presentation on consent/sexual assault; access to local resource pamphlets) immediately after baseline randomization; A-EAAA (4, 3-hr sessions) at 6-months post-randomization

Group Type ACTIVE_COMPARATOR

Usual care + A-EAAA at 6 months

Intervention Type BEHAVIORAL

Participants assigned to the waitlist control group will immediately receive a brief educational session on sexual assault that represents the current 'standard of care' at Canadian high schools (often presented by local Sexual Assault Centres or Public Health nurses). This 30-min session will involve a brief 15 - 20-minute presentation on sexual consent, respect in relationships, and sexual assault (e.g., definitions, prevalence statistics). This will be conducted by a well-trained and knowledgeable Research Assistant. Following the presentation, participants will be invited to take and read brochures provided on sexual assault, and to ask questions about the content of the presentation and brochures. At 6-months, participants will be scheduled to receive A-EAAA.
