Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Singularities Game
Singularities is an online game.
Singularities is a theory-based, community-informed, web-accessible, roleplaying game-based intervention incorporating 4 primary components: fostering healthy identity development in a safe environment; encouraging help-seeking behaviors; encouraging use of productive coping; alcohol-harm reduction; and encouraging healthy internet and social media use.
Active Comparator: Food4Thought
Food4Thought is an attention control condition in which we provide participants with similar amounts of research team contact and program contact as the intervention. Participants will play the game Pick Your Plate! A Global Guide to Nutrition, developed by the Smithsonian Science Education Center. Participants are instructed to build healthy meals using cuisine from around the world while ensuring they stick to a budget and meet all their nutritional needs. Food4Thought will be delivered via Qualtrics.

Time Frame: 3 months
Survey item from the Youth Risk Behavior Survey assessing lifetime alcohol use.
3 months
Alcohol Harm Reduction Skills
Time Frame: 3 months
Which behaviors are engaged in while drinking or partying, measured with the Protective Behavioral Strategies Scale (PBSS). Scores range from 20 to 120, with higher scores indicating more skills used
3 months
Bystander Alcohol Harm Reduction Skills

3 months
Binge Drinking
Time Frame: 3 months
Number of times where 4 or 5+ drinks (asking both, regardless of assigned/biological sex at birth to be inclusive of gender minorities) were consumed in a 2-hour period over the past 3 months, via NIAAA items
3 months
Emotional Distress Tolerance Skills
Time Frame: 3 months
Beliefs about feeling distressed or upset, measured with the Distress Tolerance Scale (DTS). Scores range from 15 to 75, with higher scores indicating a poorer outcome
3 months
Emotion Regulation and Decentering Practices
Time Frame: 3 months
How often mindfulness practices are used, measured with the Applied Mindfulness Process Scale (AMPS). Scores range from 0 to 60, with higher scores indicating a better outcome
