简要总结
Researchers at the Centers for American Indian and Alaska Native Health in the Colorado School of Public Health at the University of Colorado completed an intensive community-engaged process to rigorously adapt the Strengthening Families Program for Parents and Youth 10-14 for the cultural context of a Northern Plains reservation community, creating a program optimized for American Indian families, Thiwáhe Gluwáš'akapi (TG, sacred home in which family is made strong). This study will test the effectiveness of TG for delaying the onset of substance use among young adolescents. In response to requests from participating families and community partners to help address suicide risk among their youth, and based on preliminary evidence that the program may impact risk behaviors beyond substance use, the study will also test suicide risk outcomes among youth. Finally, in recognition of the potential for reciprocal influence on the adults participating in the program with their children, capitalizing on their motivation to make concomitant positive changes in their own lives, the current study will also examine effects on adult substance use. In summary, this study will test the effectiveness of TG for reducing risk for: (1) substance use among youth; (2) suicide risk among youth; and (3) substance abuse among adults.
详细描述
Study design overview
All 13 middle schools on the reservation will participate in this study by providing space for program groups to meet in the evenings and allowing recruitment activities at school events. A total of 480 families will be recruited into 6 cohorts across two years (spring, summer and fall). In each community, families with a child 10-12 years of age will be recruited to participate in the study. Half of recruited families will be randomly assigned to receive the Thiwáhe Gluwáš'akapi (TG) substance use prevention program and half to the comparison group, which will receive the Woyute Waśte (WW) healthy eating and exercise program. Randomization will be explained to families as part of the recruitment and consent process. Given the potential for contamination across groups with this design, the investigators will carefully examine outcomes across groups and statistically control for contamination effects as necessary. Alternative designs, including randomization at the school/community level, were rejected due to greater concerns about cross-community variability.
Recruitment and retention strategies
Schools (e.g., registration, family nights, parent-teacher conferences, holiday events) will be the main points of recruitment but additional advertising and promotion will take place at community events such as powwows, health fairs, and basketball tournaments. Written materials about the program will be distributed, along with promotional items (e.g., water bottles, magnets, and lanyards with the project name and logo). The investigators will also advertise on local community radio, which has wide reach on the reservation. Because TG has been implemented at 12 of the 13 middle schools on the reservation as a part of the adaptation study and has been well received by both families and school staff, the investigators often have inquiries about opportunities for future participation, and anticipate a positive response to recruitment efforts.
Facilitators will call families weekly to touch base with them and remind them about upcoming sessions. The investigators provide meals to families at the start of each program session, giving them opportunities to connect with other families and facilitators, fostering relationships, and making it easier for busy families to get to the sessions. Child care and transportation will be provided, as needed.

研究组 & 干预措施
Thiwáhe Gluwáš'akapi
Weeks 1-7: Weekly in-person 2.5 hour family sessions 30 minute family meal 1 hour separate youth and adult sessions
1 hour family session
干预措施: Thiwáhe Gluwáš'akapi (Behavioral)
Woyute Waśte
Respect for community and cultural values regarding research protocols precluded use of a randomized controlled design with a control group receiving no intervention, so we identified a cost-effective comparison condition program to offer value to study participants. A focus on healthy eating and exercise was of interest to community partners and not expected to directly confound the primary outcomes of the TG program (substance use and suicide risk).
Week 1 in-person 2.5 hour family session 30 minute family meal 2 hour interactive family session (3 stations) Weeks 2-7: text messages with program content and questions
