Model utilization in evaluation of a Dial-A-Dietitian system.
The purpose of this study was to determine the effectiveness of selected factors of performance of a telephone delivery system, Dial-A-Dietitian, which was established to provide nutrition information to the public. A model, developed for this use, entailed a systems approach with five phases, which included enabling factors (inputs), the interaction process, effort factors (outputs), performance (outcome), and feedback (reporting). The data analysis indicated that the Dial-A-Dietitian program was effective as measured by this model.
