Brief Summary

This study responds to Request For Application-DA-19-035, HEAL (Helping End Addiction Long Term) initiative: Preventing OUD in Older Adolescents and Young Adults (ages 16-30) by developing and implementing a culturally centered intervention to address opioid use among urban AI/AN emerging adults in California. The primary goal of this study is to compare AI/AN emerging adults who receive TACUNA plus a Wellness Circle (WC) to those AI/AN emerging adults who receive an opioid education workshop on outcomes (e.g., opioid misuse and alcohol and other drug use) over a period of 12 months. TACUNA will be a motivational interviewing group intervention that incorporates traditional practices and discussion of how to cultivate healthy social networks and cultural worlds. The Wellness gathering will be for emerging adults and people in their social network, and will focus on how social networks and cultural connectedness influence healthy behaviors. Opioid education will focus on discussion of opioid misuse within the AI/AN urban community and ways to reduce use in a culturally appropriate manner. Investigators expect those who receive TACUNA + WG will report less opioid and AOD (alcohol and other drug) use frequency, fewer consequences, less time spent around peers who use opioids and AOD, and less perceived prevalence of peer use compared to opioid education over a period of 12 months. Also, investigators will evaluate the intervention's effects on secondary outcomes of social networks and cultural connectedness. Survey data is collected at baseline, 3-months, 6-months and 12-months. Longitudinal analyses will compare intervention participant and control participants on primary and secondary outcomes.

Study Arms (2)

TACUNA

EXPERIMENTAL

Randomized participants will attend 3 virtual TACUNA workshops, focused on behavioral, physical, and spiritual domains, and designed to guide AI/AN youth to make healthy choices surrounding opioid and AOD use. They will also attend a Wellness Circle, focused on healthy social networks and engaging in traditional practices.

Behavioral: TACUNA plus Wellness Circle

Opioid education

ACTIVE COMPARATOR

Randomized participants will attend 1 virtual opioid education workshop, focused on behavioral and physical domains, and designed to guide AI/AN youth to make healthy choices surrounding opioid and AOD use.

Behavioral: Opioid Education Workshop

Interventions

TACUNA plus Wellness Circle BEHAVIORAL

TACUNA provides three virtual workshops (one hour each) that use motivational interviewing and a virtual Wellness Circle (WC). The workshops combine a 30-minute discussion of opioid, alcohol and marijuana use, and social networks with another 30 minutes focused on three different traditional practices (one per workshop). TACUNA was adapted from our three-session workshop, MICUNAY (Motivational Interviewing and Culture for Urban Native American Youth) protocol, which was developed and tested for urban AI/AN adolescents and from focus groups conducted in Year 1. For the Wellness Circle, youth will have members of their social network virtually attend these once-a-month gatherings. The WC will bring people together to celebrate health and wellness and tradition. The WC will focus on the importance of social networks in making healthy choices, and provide discussion on the role that AOD use and engagement in traditional practices among members of their social networks affect their choices.

TACUNA

Opioid Education Workshop BEHAVIORAL

The virtual opioid education workshop draws from prevention and education materials supplied and recommended by the National AI/AN Technology and Transfer Center, which is funded by SAMHSA. Materials are culturally relevant educational packages addressing opioid use through recorded webinars, toolkits, and other resources.
