Strategies for Implementing GlobalConsent to Prevent Sexual Violence in University Men

Students will be asked if they had engaged in any of seven prosocial bystander behaviors in the past 3 months (or since the last time completing the questionnaire). Items are scored as 0 = never performed, 1 = performed once, 2 = performed more than once. The numbers of participants who report engaging in at least one of seven prosocial bystander behaviors at least once are presented here.

The Sexual Experiences Survey (SES) is an assessment tool used to measure the prevalence of sexual aggression. It is designed to measure the frequency and severity of sexual aggression acts committed by an individual. The SES is a self-report questionnaire developed by researchers at the University of Michigan. The Sexual Experiences Survey - Short Form Victimization is a multi-item measure to assess unwanted sexual victimization. Surveys will be provided every six months for up to 30 months.

Perceptions of sexual violence will be assessed by respondents' rating their level of agreement with 3 statements regarding the frequency and impact of sexual violence at their university using a 5-point Likert scale ranging from "Totally disagree" to "Totally agree."

Surveys will be provided to all groups at different time points as follows:

• Students: Baseline (month 10), every 6 months up to 30 months
• Faculty: Baseline, 32 months, and 44 months
• Leaders: Baseline and 41 months
• Implementation Team: Baseline, month 25, month 29, and month 32

Leadership in implementation teams is assessed using two scales, one for implementation team supervisors, and one for implementation team staff. Each scale has 13 items and uses a 5-point Likert ranging from "Totally disagree" to "Totally agree" to assess respondent's agreement on statements about their team supervisor (for staff) or themselves (for supervisors).

For implementation team members only: The Cultural Exchange Inventory assesses the teamwork landscape of GlobalConsent implementation teams using 7 items. Respondents give their level of agreement, using a 5-point Likert scale ranging from "Totally disagree" to "Totally agree," on statements such as "The implementation team is working well together to implement GlobalConsent" and "My colleagues are devoting a lot of time and energy to maintain the collaboration of the implementation team.

For implementation team members only: The College Date Rape Attitude Survey (CDRAS), a measure intended to assess attitudes related to the risk of committing rape in adolescents and young adults, the CDRAS measures four rape-related attitudes: Entitlement, Blame Shifting, Traditional Roles, and Overwhelming Sexual Arousal. The CDRAS contains 20 items measuring attitudes toward date rape. All items require responses on a 5-point Likert scale. The responses for the attitude scale are strongly agree, agree, neutral, disagree, and strongly disagree. Scoring is reversed for appropriate items; so that high scores (5) always correspond to the most desirable (rape-related) responses.

This scale assesses respondents' attitudes towards sexual violence prevention programming by asking them to rate their level of agreement with 10 statements, such as "Implementing sexual violence prevention programming with students at our university is something I support," "...addresses a relevant problem among our students," "…would be easy for students to participate in." These statements will be rated using a 5-point Likert scale ranging from "Totally disagree" to "Totally agree."

Surveys will be provided to all groups at different time points as follows:

• Students: Baseline (month 10), every 6 months up to 30 months
• Faculty: Baseline, 32 months, and 44 months
• Leaders: Baseline and 41 months
• Implementation Team: Baseline, month 25, month 29, and month 32

This scale assesses respondents' attitudes towards the GlobalConsent program specifically by asking them to rate their level of agreement or disagreement with 10 statements, such as "Implementing GlobalConsent with students at our university is something I support," "...addresses a relevant problem among our students," "…would be easy for students to participate in." these statements will be rated using a 5-point Likert ranging from "Totally disagree" to "Totally agree."

Surveys will be provided to all groups at different time points as follows:

• Students: Baseline (month 10), every 6 months up to 30 months.
• Faculty: Baseline, 32 months, and 44 months
• Leaders: Baseline and 41 months
• Implementation Team: Baseline, month 25, month 29, and month 32

Knowledge of the law is assessed with 12 items where respondents indicate if they think the situations described are illegal (scored as 1), legal, but harmful (2), or legal and not harmful (3), with example items including "Forcing a person to have oral sex" and "Pressuring someone to have sex." Items will be re-coded such that responses indicating an accurate estimate or overestimate of the illegality and harms of sexual violence were coded as "1" and items indicating an underestimation of the illegality and harms of sexual violence were coded as "0".

Surveys will be provided to all groups at different time points as follows:

• Students: Baseline (month 10), every 6 months up to 30 months.
• Faculty: Baseline, 32 months, and 44 months
• Leaders: Baseline and 41 months
• Implementation Team: Baseline, month 25, month 29, and month 32

This form adapted the Sexual Consent Scale to ask respondents to rate their level of agreement with 12 statements about sexual consent using a 5-point Likert scale ranging from "totally disagree" to "totally agree". It includes statements such as "If a person consents to sex, one can continue sexual contact even if the person changes their mind," and "Obtaining consent for sex is just as necessary in a long-term relationship as in a new relationship."

Surveys will be provided to all groups at different time points as follows:

• Students: Baseline (month 10), every 6 months up to 30 months
• Faculty: Baseline, 32 months, and 44 months
• Leaders: Baseline and 41 months
• Implementation Team: Baseline, month 25, month 29, and month 32

This form is a combination of the Illinois Rape Myth Acceptance Scale and the College Date Rape Attitudes & Behaviors Scale. This assesses attitudes towards sexual assault and rape by asking respondents to rate their level of agreement or disagreement with 15 statements using a 5-point Likert scale ranging from "totally disagree" to "totally agree". Statements include "If a woman dresses in a sexy dress, she is asking for sex," and "When guys rape, it is usually because of their strong desire for sex."

Surveys will be provided to all groups at different time points as follows:

• Students: Baseline (month 10), every 6 months up to 30 months.
• Faculty: Baseline, 32 months, and 44 months
• Leaders: Baseline and 41 months
• Implementation Team: Baseline, month 25, month 29, and month 32

This form assesses the perceptions of respondents in their university's faculty and leaders' potential response to sexual violence on their university campus. Questions ask about behaviors of abuse, sexual assault, and stalking, and their level of agreement or disagreement with whether faculty and leaders would believe a student reporting experiencing these behaviors, respect a student who reported experiencing these behaviors, or admire a student intervening in these behaviors. Agreement is assessed using a 5-point Likert scale ranging from "totally disagree" to "totally agree"

Surveys will be provided to all groups at different time points as follows:

• Students: Baseline (month 10), every 6 months up to 30 months
• Faculty: Baseline, 34 months, and 49 months
• Leaders: Baseline and 41 months
• Implementation Team: Baseline, month 25, month 29, and month 32

Students only: This form asks respondents' agreement or disagreement on 5 alcohol-related questions focusing on decision-making, behavior, and sexual violence. It assesses agreement or disagreement using a 5-point Likert ranging from "totally disagree" to "totally agree".

Students only: Empathy for rape victims will be assessed with a modified version of the Rape Empathy Scale (RES). This assessment includes 10 items where participants were asked to choose between two statements, one of which reflected greater empathy towards rapists ("I understand the helplessness a rapist might feel during a rape since he cannot control his actions") and one of which reflected greater empathy towards victims ("I understand the helplessness a victim might feel during a rape"). Responses are scored as 1 (more empathy for victim) or 0 (more empathy for perpetrator) and total scores range from 0 to 10 where higher scores indicate more empathy towards rape victims.

Students only: This is a 7-item scale measuring agreement or disagreement with statements focusing on sexual communication. Agreement and disagreement is assessed using a 5-point Likert ranging from "totally disagree" to "totally agree."

Students only: Bystander Self-Efficacy will be measured using the Bystander Efficacy Scale, which was developed for a project that evaluated the effectiveness of a sexual violence prevention program based on preventing antecedents to sexual violence by increasing prosocial bystander behavior. On this measure, participants are asked to indicate their confidence, on a 3-point scale, in performing each of 10 bystander behaviors (e.g., "Speak up to a guy who is making excuses for using physical force in a sexual relationship."). Scores are created by subtracting the mean of the 10 items from 100 to create a scale of perceived ineffectiveness; thus, higher scores indicate lesser effectiveness.

Students only: Readiness to Intervene will be measured using three intent-to-help subscales.

• Intent to Help Friend Scale: Sexual Abuse
• Intent to Help Friend Scale: Intimate Partner Violence Intent to help is an attitude that is related to bystander action. Participants will be asked how likely they are to take different bystander actions.

The second Intent to Help subscale focuses on participants' intent to help strangers in both sexual abuse and intimate partner abuse situations.

Responses range from 1 (not at all likely) to 5 (extremely likely). The average is calculated from the answers across the items to score this measure.

Students only: Depression will be measured using the Patient Health Questionnaire 9 (PHQ-9): The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring, and measuring the severity of depression. The PHQ-9 is completed by the participant in minutes and is rapidly scored by a clinician. The PHQ-9 can also be administered repeatedly, which can reflect the improvement or the worsening of depression in response to treatment. PHQ-9 scores of 5, 10, 15, and 20 represent mild, moderate, moderately severe, and severe depression.

Students will complete the Generalized Anxiety Disorder 7-item (GAD-7), which is a quick and easy tool to help identify patients with anxiety and monitor treatment response. The GAD-7 has been validated as a diagnostic tool and a severity assessment scale. The scale consists of 7 items. The total score can range from 0 to 21, and it indicates the severity of anxiety as follows:

0 to 4: Minimal anxiety 5 to 9: Mild anxiety 10 to 14: Moderate anxiety 15 to 21: Severe anxiety

Students only: The Disability Assessment will be assessed by using the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), which is a generic assessment instrument for health and disability used across all diseases, including mental, neurological and addictive disorders, applicable in both clinical and general population settings. It is a tool to measure the level of disability and functioning in six domains. The answers rate each question on a scale from 0 (none) to 4 (extreme or cannot do).

There are three scoring methods: simple score, complex score, or average score. The simple score is the sum of the ratings for each question. The complex score is the sum of the ratings multiplied by a weight factor. The average score is the mean of the ratings for each domain.

Students only: The DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure-Adult is a tool designed to assess mental health domains that are important across various psychiatric diagnoses. It consists of 23 questions that evaluate 13 psychiatric domains, such as depression, anxiety, somatic symptoms, and more. Each item on the measure is rated on a 5-point scale (0=none or not at all; 1=slight or rare, less than a day or two; 2=mild or several days; 3=moderate or more than half the days; and 4=severe or nearly every day). A mild (i.e., 2) or greater rating on any item within a domain may guide additional inquiry and follow-up to determine if a more detailed assessment for that domain is necessary. Consistently high scores on a particular domain may indicate significant and problematic symptoms for the individual that might warrant further assessment, treatment, and follow-up

This scale asks respondents to indicate whether and how often they completed proactive bystander behavior actions in the last 6 months (the time between each survey wave). Behaviors include "I have encouraged others to learn more and get involved in preventing sexual or dating violence," and "I have told guys not to talk about women in sexually degrading ways," and response options for each statement are (0) No, I have not done this in the last 6 months, (1) Yes, once in the last 6 months, and (2) Yes, more than once in the last 6 months.

This scale asks respondents whether and how often they completed reactive bystander behavior actions in the last 6 months (the time between each survey wave). Actions include "I have expressed concern or offered help to a woman who said she had an unwanted sexual experience but didn't call it 'rape'," "I have reported formally to an authority a guy who used physical force against a women," and "I have intervened with a guy's action because I wanted to stop an act of sexual violence." Responses options for each statement are (0) I experienced this situation in the last 6 months and did NOT act, (1) Yes, once in the last 6 months, (2) Yes, more than once in the last 6 months, and (9) I did NOT experience any situation like this in the last 6 months.
