The Hastiin Bidziil (Strong Man) Intervention for Substance Use

This study is testing a program called Hastiin Bidziil (Strong Man) to help reduce substance use in American Indian men. You might be able to join if you are an American Indian man, age 18 or older, who has used alcohol or drugs (not just tobacco), and live near Fort Defiance or Chinle, AZ. The study will compare Hastiin Bidziil, which is a culturally adapted behavioral therapy, to a control group that learns about vehicle maintenance. Researchers will measure how many days you use substances over an 8-month period to see if the Hastiin Bidziil program is effective. The current status of this study is unclear, but it plans to enroll 160 participants.
