Researchers tested a program called Weaving Healthy Families that brings Indigenous families together for 2.5-hour sessions with meals, lessons about health and communication, and family activities. The study followed 218 adults and 354 youth from Native American communities over a year. Both adults and youth who participated in the program showed significant decreases in alcohol use and drinking problems compared to before they started. The program appears to be one of the most effective ways to help Indigenous communities reduce harmful drinking, since it was designed specifically for Native American families and their values.

The Quick Take

  • What they studied: Whether a family-based program called Weaving Healthy Families could help Native American adults and young people drink less alcohol and avoid alcohol-related problems.
  • Who participated: 218 Native American adults and 354 Native American youth from Indigenous communities across the United States. Participants were tracked for one year with check-ins at the start, end of the program, and at 6, 9, and 12 months after.
  • Key finding: Adults who completed the program showed meaningful drops in alcohol use disorder symptoms, risky drinking, and the number of drinks consumed per month. Youth also showed improvements, with girls showing larger decreases than boys. These improvements lasted through the 12-month follow-up period.
  • What it means for you: If you’re part of a Native American community struggling with alcohol use, this program offers a culturally respectful way to reduce drinking that involves your whole family. The benefits appear to last at least a year. However, this program works best when communities choose to participate and adapt it to their own needs.

The Research Details

Researchers used a stepped-wedge trial design, which means different communities started the program at different times. This design helps researchers compare what happens when communities have the program versus when they don’t. The study was longitudinal, meaning they followed the same people over time (one year total) and measured their alcohol use at five different points: before the program, right after, and then at 6, 9, and 12 months later.

The Weaving Healthy Families program consists of 2.5-hour sessions that start with a shared family meal. Each session teaches about nutrition, healthy communication, and family traditions that support wellness. The program was developed over more than 10 years working directly with Indigenous communities, making sure it respected Native American values and knowledge.

Researchers used standard alcohol measurement tools (like the Alcohol Use Disorders Identification Test) to track changes in drinking patterns and alcohol-related problems. They used advanced statistical methods to analyze the data while accounting for the fact that people were nested within families and communities.

This research approach is important because it tests the program in real-world Indigenous communities rather than in a lab setting. By involving communities in designing and running the study, researchers made sure the program actually fits with how Native American families live and what they value. The stepped-wedge design also allows communities to eventually all receive the program while still providing good scientific evidence about whether it works.

This study has several strengths: it followed a large number of people (572 total) over a full year, it measured outcomes at multiple time points so researchers could see if improvements lasted, and it was grounded in over a decade of community partnership. The study was registered in a clinical trial database before it started, which increases trust in the results. However, the study didn’t include a control group that received no program, so some improvements might be due to other factors like increased attention or seasonal changes.

What the Results Show

Adults who completed the Weaving Healthy Families program showed significant improvements in multiple measures of alcohol use. Alcohol use disorder symptoms decreased meaningfully, and the number of drinks consumed in the past month dropped significantly. These improvements were visible right after the program ended and continued through the 12-month follow-up period, suggesting the benefits lasted.

Youth participants also showed improvements, with reductions in alcohol use disorder symptoms and past 30-day drinking. Interestingly, girls showed larger improvements than boys in some measures, which suggests the program may work differently for different genders.

The program also appeared to reduce feelings of guilt and shame related to drinking, which is important for mental health and recovery. These improvements happened across different age groups and communities, suggesting the program works broadly across Indigenous populations.

The fact that improvements were sustained at 12 months is particularly important because it shows this isn’t just a short-term effect—families appear to maintain healthier drinking patterns long after the program ends.

Beyond the main alcohol-related improvements, the program appeared to strengthen family communication and relationships. The shared meals and family activities seemed to create positive connections that supported healthier choices. The program also addressed nutrition and overall family health, not just alcohol use, which may have contributed to broader wellness improvements.

This study replicates and expands on earlier pilot testing of the Weaving Healthy Families program, confirming that the initial promising results hold up in a larger, more rigorous study. The findings align with research showing that family-based interventions tend to be more effective than programs targeting individuals alone. This study is notable because most alcohol prevention research focuses on non-Indigenous populations, so having strong evidence for an Indigenous-specific program fills an important gap.

The study didn’t include a comparison group that received no program, so we can’t be completely certain that all improvements were due to the program itself rather than other factors. Some people who started the program may have dropped out, and the study didn’t fully account for this. The study focused on Indigenous communities that chose to participate, so results might not apply to communities that are less engaged. Additionally, self-reported drinking measures can sometimes be underestimated due to social desirability bias (people wanting to appear better than they are).

The Bottom Line

Strong evidence supports offering the Weaving Healthy Families program to Native American communities interested in reducing alcohol misuse. Communities should consider implementing this program as part of their health services. For individuals and families, participating in this program appears to offer real benefits for reducing harmful drinking. The program is most effective when communities adapt it to fit their specific cultural practices and values. Confidence level: Moderate to High (based on the study design and results, though the lack of a control group prevents absolute certainty).

This program is designed for and most beneficial to Native American adults and youth who want to reduce alcohol use or prevent alcohol problems. It’s particularly valuable for communities experiencing health disparities related to alcohol. Family members of people struggling with alcohol should also consider participating, as the family-based approach helps everyone. This program may be less relevant for non-Indigenous populations, as it’s specifically designed around Indigenous values and knowledge. People with severe alcohol addiction may need additional medical treatment beyond this program.

Participants showed improvements immediately after completing the program sessions. These improvements continued and were still present at 6, 9, and 12 months. Most people should expect to see meaningful changes within the first few months of participation, with sustained benefits if they continue applying what they learned.

Want to Apply This Research?

  • Track weekly drinks consumed and rate feelings of guilt or shame on a 1-10 scale. Users can log these metrics weekly and watch their trends over 12 weeks to see if they’re moving in a positive direction, similar to how the research study measured outcomes.
  • Set a goal to attend family meals or activities together at least once per week, and use the app to log these family connection moments. Users can also track communication improvements with family members and note positive interactions, reinforcing the family-centered approach that makes this program work.
  • Create a 12-month tracking dashboard that mirrors the study’s follow-up schedule (baseline, 6 weeks, 3 months, 6 months, 9 months, 12 months). Users can complete brief check-ins at these intervals to monitor their alcohol use patterns, family relationships, and overall wellness, allowing them to see long-term progress similar to the research study.
