Rethinking Developmental Prevention

This paper presents some recent thoughts about the nature of developmental prevention, and illustrates some of these ideas by showing how a community-based early intervention project in a disadvantaged area of Brisbane has been designed and implemented. Developmental prevention involves a focus on key life transitions (such as the transition to school), on multiple levels of the social ecology (individual, family, school, community), and on the transformation of social institutions (not just the implementation of specific programs). Developmental prevention is more than early childhood intervention, although there are good reasons for implementing early-in-life interventions as part of an overall prevention strategy, and it is more than risk-focussed prevention, although risk and protective factors constitute a valuable analytical tool. 'Early' should mean 'early in the developmental pathway leading to problems,' and encompass interventions at any life phase (including adulthood). Analysis of the fit, or lack of fit, between the resources that people need to deal with difficulties, challenges or obstacles, and the resources (internal or external) available to them to overcome these difficulties, is fruitful in addition to thinking about risk and protective factors. The conceptual and programmatic challenge is to design interventions built on evidence but with the capacity to be modified in the light of outcomes achieved. Interventions must comprehend the complex ecologic and policy contexts that influence crime and related problems, and yield insights for policy and institutional reform.
