PROSPER community-university partnership delivery system effects on substance misuse through 6 1/2 years past baseline from a cluster randomized controlled intervention trial.

ABSTRACT:

Objective

To examine the effects of a delivery system for evidence-based preventive interventions through 12th grade, 6.5 years past baseline.

Method

A cohort sequential design included 28 public school districts randomly assigned to the partnership delivery system or usual-programming conditions. At baseline, 11,960 students participated. Partnerships supported community teams that implemented a family-focused intervention in 6th grade and a school-based intervention in 7th grade. Outcome measures included lifetime, current misuse, and frequencies of misuse, for a range of substances. Intent-to-treat, multilevel analyses of covariance of point-in-time misuse and analyses of growth in misuse were conducted.

Results

Results showed significantly lower substance misuse i
