Brief Summary
The target population is students attending high schools in small rural towns in the 14 counties that partially or fully fall within the Cherokee Nation reservation. Following recruitment of 20 school-based clusters, clusters are allocated to either the intervention condition or delayed-intervention control condition using constrained randomization. Constrained randomization helps to ensure balanced cluster sizes as well as similar levels of risk between the intervention and control at baseline. Study participants include all 10th grade students enrolled in the participating study high schools and students will be followed into the first year after their expected graduation.

Outcome Measures
Primary Outcomes (4)
Number of Days of Alcohol Use
The number of days of alcohol use in the past 30 days is compared between study arms.
Surveys were administered each fall and spring semester from baseline (fall of 10th grade) to spring of 12th grade (up to 31 months and 19 days)
Number of Days of Heavy Alcohol Use
The number of days of heavy alcohol use in the past 30 days is compared between study arms. Heavy alcohol use is defined as having at least four (among young women) or five (among young men) alcoholic drinks within a couple of hours.
Surveys were administered each fall and spring semester from baseline (fall of 10th grade) to spring of 12th grade (up to 31 months and 19 days)
Number of Days of Marijuana Use
The number of days of marijuana use in the past 30 days is compared between study arms.
Surveys were administered each fall and spring semester from baseline (fall of 10th grade) to spring of 12th grade (up to 31 months and 19 days)
Number of Days of Opioid Misuse
The number of days of opioid drug misuse use in the past 30 days is compared between study arms.
Surveys were administered each fall and spring semester from baseline (fall of 10th grade) to spring of 12th grade (up to 31 months and 19 days)
Secondary Outcomes (16)
Social Support From Parent/Caregiver
Surveys were administered each fall and spring semester from baseline (fall of 10th grade) to spring of 12th grade (up to 31 months and 19 days)
Social Support From Friend
Surveys were administered each fall and spring semester from baseline (fall of 10th grade) to spring of 12th grade (up to 31 months and 19 days)
Social Support From Teacher
Surveys were administered each fall and spring semester from baseline (fall of 10th grade) to spring of 12th grade (up to 31 months and 19 days)
Social Support From Other Adult
Surveys were administered each fall and spring semester from baseline (fall of 10th grade) to spring of 12th grade (up to 31 months and 19 days)
Perceived Availability of Alcohol
Surveys were administered each fall and spring semester from baseline (fall of 10th grade) to spring of 12th grade (up to 31 months and 19 days)

Study Arms (2)
Preventive Intervention
EXPERIMENTALStudents in schools assigned to the preventive intervention study condition will take part in the Connect school-based prevention program and the community-level Communities Mobilizing for Change and Action (CMCA) intervention.
Control Group
NO INTERVENTIONStudents in schools assigned to the control group will not receive the Connect and CMCA interventions. Schools in the control group will receive usual school and community prevention and will be offered the trial's programs after the end of this three-year study.
Interventions
The community-level intervention Communities Mobilizing for Change and Action (CMCA) will involve educating and organizing of adult volunteers and consent will be assumed by their participation. Trainings and tools will be provided, including Family Action Kits, to support local families, community organizations and citizens, including information on national and local opioid and other drug use, evidence-based policies, programs and practices, and how to motivate and create family and local action for drug prevention.
The Connect program includes school-based screening, brief intervention and referral, and will be treated as part of the participating schools' prevention programs. A computer-based screening and brief intervention will be supported by Cherokee Nation Behavioral Health (CNBH) supervised Connect coaches universally, to reduce potential stigma associated with speaking to a Connect coach and to reinforce drug free norms among all students. Follow-up of moderate to high-risk youth will be conducted by a Connect Coach through Zoom, other electronic communication, or in-person visits, with referral to Cherokee Nation or community services if deemed necessary.
