Volunteers in probation: A research note on evaluation

Despite the widespread adoption of volunteers in courts, probation, and parole, surprisingly little hard evidence exists demonstrating their effectivenes. Several studies are reviewed and one is reported on here. These studies suggest that volunteers are not effective. The reason for this may be that volunteers compete unsuccessfully with other aspects of clients' environment. Reasons for the adoption of volunteer programs may include selection biases that falsely tend to make volunteers seem effective. Recommendations for definitive study of volunteer programs are made.
