Abstract:
Recent meta-analyses of drug-court studies recognized the poor methodological quality of the evaluations, with only a few being randomized. This article critiques the design of the randomized studies from a statistical perspective. Learning points are identified for future drug-court studies and are applicable to evaluations both of other specialist courts and of court-based interventions more generally. The specific issues covered are randomization, describing the intervention, and baseline characteristics; study outcomes, and sample size calculations; in-program and postprogram behavior, analysis plan, and presentation of results.

Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
