Using a Progressive Ratio Schedule of Reinforcement as an Assessment Tool to Inform Treatment.

A handful of studies have examined the utility of progressive ratio schedules (PRs) of reinforcement in treatment development and treatment efficacy. The current case study explored the utility of PRs as an assessment tool to inform a differential reinforcement treatment package. A PRs assessment was used to identify the breaking point of a functional communicative response before and after treatment. The breaking point was used as the initial reinforcement schedule during treatment. Following treatment, the communicative response increased during a posttest PRs assessment, suggesting the efficacy of the treatment package.
