Abstract

The paper describes one of the first attempts to evaluate an obesity prevention intervention that was informed by systems thinking and deliberately addressed the complexity within each school setting. A quasi-experimental design was adopted, and the intervention design included the facility for each school to choose and adopt interventions that were specific to their school context and priorities. This, in turn, meant the expectation of differential behavioural effects was part of the initial design and therefore a comparison of outcomes by intervention school was warranted.
