Abstract
Objectives: The crime prevention evaluation literature has identified several potential side effects of interventions. These often-unintended consequences occur at different stages of prevention processes, including before official start dates. They can improve or reduce intervention impacts. Evaluations using before-and-after designs with or without controls can fail to identify these effects. We describe a longitudinal framework to guide the design and evaluation of interventions that can account for these side effects when causal mechanisms are better understood. // Methods: Our time-course framework provides a comprehensive assessment of the prevention process. Using place-based examples as illustrations, it builds on previously identified temporal benefits and backfires—such as anticipatory benefits, residual deterrence, and initial backfire—that have never been systematically organized into a single framework. We show how our framework can be incorporated into the EMMIE framework for assessing prevention utility. // Results: The proposed time-course framework links together all temporal effects, their underlying mechanisms, and shows how they can vary by context. // Conclusions: The framework suggests that considering all decisions within these timelines will be more cost-effective and produce greater crime reductions in the long run. By considering the mechanisms that can be triggered at various points in an intervention’s time-course, we can better design experiments to test them and generate stronger evaluations of programs.
