Funding was obtained from the California Office of Traffic Safety (OTS 057702) to conduct the project titled "Optimization of the Probation Violator Hearing Format." The project scope, as stated in the grant application, is "...to develop and evaluate new strategies for the probation violator hearing." Major project objectives are to: develop a behaviour modification strategy (including contingency contract methodologies) for use by the DIA in the probation violator hearing setting; train selected DIA staff methodologies; and implement and evaluate probation violator hearing formats in selected pilot field offices. The first three objectives have been met by prior publications (Tosti, Hagen, & Williams, 1978; Williams & Hagen, 1978) and by training more than 100 driver improvement personnel. An interim report (Hagen & Williams, 1979) was prepared. The interim report contributed to the creation of a divisional task force which explored several issues relating to driver improvement performance and work climate. The present report overviews the completed objectives and fully documents project implementation and evaluation activities. (Author)
