Recruitment and retention of American Indian youth and caregivers in a culturally adapted prevention program.

This article seeks to understand to what extent cultural engagement and substance use risk factors influence families' decisions to participate, and ultimately complete, a culturally grounded substance use prevention program. Using data from a 14-week culturally oriented family-based substance use prevention program, we examine predictors of successful recruitment and retention of American Indian youth and their caregivers. Guided by the theoretical model for developing culturally specific preventions, the community-based approach to recruitment resulted in 85.

Social Network Analysis of Diffusion Among American Indian Youth in a Culturally Adapted, Family-focused Prevention Program.

Diffusion can contribute to the spread of preventive intervention effects from participants to non-participants, but best practices for randomized trials prevent contamination of conditions. These practices conflict with cultural values of community benefit, which are salient among American Indians. This study embedded social network measures within a randomized trial of the Bii-Zin-Da-De-Dah (BZDDD) family-focused prevention program to characterize youth's social networks, describe the nature and content of sharing, and test for diffusion effects on cultural engagement (ethnic identification, cultural socialization, cultural practices) and substance use.
