In this effective trial, teenagers who attended the
SAAF-T meetings in 10th grade were interviewed again in
12th grade. In comparison to the nutrition/exercise
group, the teens in the SAAF-T group
- 36% fewer conduct problems
- 32% less frequent substance use
- 47% fewer substance use problems
- Reduced depressive symptoms
- Decreased frequency of unprotected intercourse
- Increased condom efficacy
The nutrition/exercise group was effective in the sense
that its participants reported 14.5% more healthful
behaviors at follow-up in comparison to the SAAF-T group.
From a cost-effectiveness standpoint, baseline
and follow-up assessments revealed that of the 473
youth who participated:
- Incremental per participant costs were $168
- Incremental per participant effects prevented:
- 3.39 episodes of alcohol use
- 1.36 episodes of binge drinking
- Therefore, the SAAF-T Program
- $50 per reduction in alcohol use episode
- $123 per reduction in binge drinking
At thresholds of $100 and $440, cost-effectiveness
acceptability curves revealed that relative to the
attention control intervention:
- 90% probability of
cost-effectiveness for decreased alcohol use and
instances of binge drinking
suggest the SAAF-T intervention is a potentially
cost-effective means for decreasing alcohol use and
episodes of binge drinking in rural African American
