The project, based on social learning theory, was conducted in several phases. First, a process evaluation of the current contact investigation process was conducted. Results guided the development of a revised contact investigation protocol, a software program for notebook computers designed to enhance protocol implementation, and a behavioral intervention to educate contact investigators in the use of the protocol and software. A formative evaluation of the intervention, protocol, and software was used to refine the procedures, which were then implemented throughout the State of Alabama. An impact evaluation was then conducted to assess the effectiveness of the procedures. If the impact evaluation results weresatisfactory, the behavioral intervention and contact investigation procedures would be developed in a format that could be exported to other areas and settings.
