(Winters 2007a). There are a number of advantages of schoolbased
BIs for substance-using adolescents. Firstly, students usually
are not dependent on substances yet, but a number of these adolescents
may exhibit mild or moderate use, which makes them good
candidates for BI. Secondly, research has shown that BIs can be
conducted during school or in after-school hours, making the intervention
very accessible to students. Finally, the growing volume
of BI material on how to conduct BI sessions means that they can
often be run by staff available to schools, and not only by health
professionals (Winters 2007a). There is also some research that
suggests that BIs may work in other settings as well, such as family
interventions for school-going adolescents in terms of alcohol, tobacco
and marijuana use (Spoth 2001). Recently, research has also
suggested that web-based BI programmes may be useful in reducing
substance use in young adults (for example Bingham 2010).
Despite the promise of school-based BI programmes, meta-analyses
of school-based interventions have not yet been conducted
