Heavy episodic drinking and sexual assault are problematic on college campuses. This study includes a randomized controlled trial of Positive Change (+Change), an integrated alcohol and sexual assault prevention program, compared to an attention-matched control condition across two universities in reducing alcohol use, sexual assault victimization, sexual assault perpetration, and increasing sexual assault bystander intervention. This study will also test the efficacy of +Change plus Booster session, an identical version of +Change delivered 6 months after the baseline, compared to +Change alone in long-term reductions in alcohol use, sexual assault victimization, sexual assault perpetration, and increases in sexual assault bystander intervention. This research is the next step of a NIAAA-funded planning grant (R34AA025691).
Aim 1: Test the efficacy of Positive Change (+Change) among college students in each risk group (cisgender heterosexual men; cisgender heterosexual women; LGBTQ). Students aged 18-25 who engage in heavy episodic drinking will be recruited from 2 large public universities (n = 3,300) and will be randomly assigned to +Change, +Change plus +Booster, or an attention control. Alcohol use, sexual assault (victimization and perpetration), and bystander intervention will be assessed at baseline, 3-, 6-, 9-, and 12-month follow-ups.
H1a: +Change conditions (+Change and +Change plus Booster) will result in less alcohol use, less sexual assault (victimization and perpetration), and more bystander intervention compared to the control condition at 3-month follow-up and maintained at 6 months.
H1b: +Change plus booster at 6-months will maintain less alcohol use, less sexual assault (victimization and perpetration), and more bystander intervention compared to +Change over 9- and 12-month follow-ups (i.e., less decay of change).
Aim 2: Investigate theoretical mechanisms through which +Change conditions impact alcohol use (e.g., descriptive drinking norms, drinking to cope with minority stress for LGBTQ students), sexual assault victimization and perpetration (e.g., sexual assault-related norms, sexual assault resistance self-efficacy, hypergender ideology), and bystander intervention (e.g., bystander intervention self-efficacy).
Exploratory Aim: Examine +Change efficacy among LGBTQ subgroups (lesbian, gay, bisexual, trans, non-binary gender, gender queer, queer/questioning, intersex, asexual).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control | Placebo Comparator | A healthy lifestyles attention control will be used as the control condition. We will match the control and intervention conditions on content (text, pictures, number of pages); type (interactive vs. psychoeducation); and average completion time. |
|
| Positive Change (+Change) | Experimental | This is an integrated social norms-based personalized feedback intervention for college students targeting alcohol misuse and sexual assault. It targets alcohol, sexual assault victimization risk, sexual assault perpetration, and bystander intervention. It is tailored by gender and sexual orientation. |
|
| Positive Change (+Change) Plus Booster | Experimental | This is an integrated social norms-based personalized feedback intervention for college students targeting alcohol misuse and sexual assault. It targets alcohol, sexual assault victimization risk, sexual assault perpetration, and bystander intervention. It is tailored by gender and sexual orientation. It is provided at baseline and a booster at 6 months. |

| Positive Change (+Change) | Behavioral | This is an integrated social norms-based personalized feedback intervention for college students targeting alcohol misuse and sexual assault. It targets alcohol, sexual assault victimization risk, sexual assault perpetration, and bystander intervention. It is tailored by gender and sexual orientation. |
| Measure | Description | Time Frame |
|---|---|---|
| Changes in Alcohol use | Number of drinks will be assessed using the daily drinking questionnaire. Higher scores indicate higher alcohol use. | 3-, 6-, 9-, and 12-months |
| Changes in Sexual Assault Victimization | Sexual assault victimization severity will be assessed using a modified version of the Sexual Experiences Survey. Responses are rated on number of times each experience occurred (0, 1, 2, 3+). Higher scores indicate higher sexual assault victimization. | 3-, 6-, 9-, and 12-months |
| Changes in Bystander Intervention | Bystander intervention behavior will be assessed using the 44-item Bystander Behavior Scale to assess engaging in bystander behavior with friends. Responses indicate if the participant engaged in each bystander behavior with a friend or not, or if they had no opportunity to engage in the behavior. Higher scores indicate higher bystander intervention behaviors. | 3-, 6-, 9-, and 12-months |
| Changes in Sexual Assault Perpetration | Sexual assault perpetration severity will be assessed using a modified version of the Sexual Strategies Survey. Participants check all items that apply. Higher scores indicate higher sexual assault perpetration. | 3-, 6-, 9-, and 12-months |
