Research Roundup

Mike from Drug and Alcohol Findings has alerted me to a couple of papers that will be of interest to readers.

Results indicate that alcohol and marijuana use increased from pre-intervention across subsequent time periods for all youth. The drug use of the American Indian youth in the treatment group increased on some measures. Specifically, they reported a steeper trajectory in the amount and frequency of alcohol and marijuana use compared to the youths in the treatment groups with other racial/ethnic identifications. The implications of these findings for the development of culturally grounded prevention programs for multi-ethnic, urban American Indian youth are discussed.

They say:

This research provides a specific example, but also makes a strong global argument, for the need to develop and evaluate prevention programs that are culturally grounded in the worldview of the target group.

The second, Variable- and Person-Centered Approaches to the Analysis of Early Adolescent Substance Use: Linking Peer, Family, and Intervention Effects With Developmental Trajectories, found:

treatment effects both on decreasing the likelihood of initiating substance use and on the rate of growth in substance use among those who initiated use. Person-centered analyses revealed the following five trajectories of early substance use: (1) no use, (2) low/rare use, (3) early accelerating use, (4) late-accelerating use, and (5) early high but decreasing use. Of note, random assignment to the ATP (Adolescent Transitions Program) intervention was strongly predictive of following the decreasing-use trajectory. In addition, the early high but decreasing group was most likely to engage in the Family Check-Up and linked intervention services.

They say:

These findings suggest that covariates of early adolescent substance us, as well as the effectiveness of prevention strategies, vary as a function of the developmental pattern underlying early adolescent risk.
