Community Trial in the Cherokee Nation

Community Randomized Trial in the Cherokee Nation: Connect and CMCA for Preventing Drug Misuse Among Older Adolescents

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 919 (actual)
• Sponsor: Emory University · Academic / Other
• Sex: All
• Age: 15 Years – 17 Years
• Healthy volunteers: Not accepted

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.

Detailed description

The national public health opioid crisis has disproportionately burdened rural White populations, and disproportionately burdened American Indian populations. Therefore, the Cherokee Nation (CN) and Emory University public health scientists have designed an opioid prevention trial to be conducted in at-risk rural communities in the CN (in northeast Oklahoma) with primarily White and American Indian adolescents and young adults. The goal of this study is to implement and evaluate a theory-based, integrated multi-level community intervention designed to prevent the onset and escalation of opioid and other drug misuse. The researchers propose a cluster randomized trial building directly on the success of their most recent previous trial, which demonstrated that the intervention effectively reduced alcohol and other drug use among American Indian and other youth living within the CN. Two distinct intervention approaches-community organizing as implemented in the established Communities Mobilizing for Change and Action (CMCA) intervention protocol, and universal school-based brief intervention and referral as implemented in the established Connect intervention protocol -will be expanded and integrated to further enhance effects in preventing and reducing opioid misuse. The CMCA and Connect interventions were originally designed to target adolescent alcohol use but nevertheless showed significant beneficial effects on use of other drugs, including prescription drug misuse. The proposed study will: (1) further improve the design of the interventions with increased focus on opioids, (2) test the expanded, integrated versions in a cluster randomized trial, and (3) design and test new systems for sustained implementation within existing structures of the Cherokee Nation. Building upon the extant prevention science evidence, this study will respond to a gap in evidence concerning opioid misuse prevention among at-risk adolescents transitioning to young adulthood among American Indian and other rural youth.

Interventions

Type	Name	Description
BEHAVIORAL	Connect Program	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.
BEHAVIORAL	Communities Mobilizing for Change and Action (CMCA)	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.
