A high-profile multi-site clinical trial of a probation model using contingency management principles was widely seen as proving the model’s ineffectiveness. But site differences suggest that some outcomes varied by implementation success. Further, although the main article in Criminology and Public Policy included the largely negative pre-registered outcomes, it did not include the pre-registered substance use outcome, which was significantly improved. The trial thus supports a more encouraging conclusion than is commonly believed.
