Experiments test ‘new’ ideas about interventions that might produce better outcomes. Re-entry requires that the intervention should be offered at the transition point (from prison to community) and in the community. In general, the experiment requires the researchers to differentiate the ‘new’ approach from usual practice. The answer lies in the design and measures of the experiment. It is important to make sure that the intervention will be designed and implemented in such a manner that makes it operationally different from traditional services. Each experiment must include measures to determine the content and dosage of the new intervention as well as the traditional practice. This special edition is devoted to examining how these issues are handled in four different experiments, as well as comments from members of a Data Safety Monitoring Board (DSMB) on the efforts to monitor studies. Together, the articles point to the need to measure the fidelity and adherence of new innovations.
