Abstract

Substance use disorders occur at a disproportionately higher rate for American Indian adults in the United States, yet there is a limited understanding of how those in the recovery process perceive their American Indian culture as a meaningful component of their treatment. This study intended to address this gap in the research and to assist with tribal efforts in treating substance use disorder among a small sample of American Indian adults enrolled in a Northern Plains tribe by assessing cultural identification and the importance, contribution, and incorporation of cultural traditions, practices, and ways of living into the recovery process. Results indicated that higher scores on American Indian cultural identification significantly predicted higher ratings on the perceived importance and incorporation of traditional and cultural practices into treatment; however, this relationship was not found for contribution, suggesting other factors beyond culture may be perceived as attributing to treatment outcomes to a greater extent. Overall, these findings highlight the valuable role that cultural identity and engagement in cultural activities can have for American Indian adults receiving substance abuse treatment.
