Objectives: We examined universal preventive intervention effects on adolescents’
exposure to opportunities for substance use and on illicit substance use in
the long term.
Methods: Public schools (N=22) were randomly assigned to the Iowa
Strengthening Families Program (ISFP) or a control condition. We used odds
ratio (OR) calculations and structural modeling to test the effects of the ISFP in
the 6th grade on exposure to substance use across adolescence, as well as on
12th-grade illicit substance use occurring via reductions in exposure.
Results: The ISFP was associated with reduced exposure to illicit substance
use (1.25£OR£2.37) that was, in turn, associated with reduced 12th-grade
substance use (2.87£OR£6.35). The ISFP also reduced the rate of increase in
exposure across adolescence (B=–0.37; P<.001), which was associated with the
likelihood of 12th-grade illicit substance use (B=0.30; P=.021), with a significant
indirect effect (B=–0.11; P=.048).
Conclusions: The ISFP in the 6th grade reduced substance use through a
‘‘protective shield’’ of reduced exposure. The relative reduction rate was 49%,
which suggests that universal prevention shields can contribute to significant
reductions in illicit substance use among adolescents.
