A Computer-Based Dietary Counseling System.
Slack, Warner V.; And Others
Journal of the American Dietetic Association, v69 n4 p385-390 Oct 1976
The preliminary trial of a program in which principles of patient-computer dialogue have been applied to dietary counseling is described. The program was designed to obtain historical information from overweight patients and to provide instruction and guidance regarding dietary behavior. Beginning with a teaching sequence, 25 non-overweight participants responded to 375 questions (items) on the cathode-ray screen. Questions were divided into three sections: dietary history, analysis of food intake for a usual day, and diet and menu planner. As questions appeared on the screen, the participants read them aloud, explained their understanding to an assistant, and answered at the keyboard. This initial trial sought to study the process of dietary interviews by computer, the read-aloud procedure served to uncover defects in word choice, instructions, and interview strategies. Difficulties in understanding were evident in 12% of the items. Use of the keyboard evoked more difficulties than favorable reactions (7% vs. 4%) during the teaching sequence, whereas favorable responses to the keyboard were more frequent than difficulties (2% vs. 1%) during the dietary sections. While the computer interviews demand clarity and structure from the writer of the program, they do facilitate the writing and revision by compiling a complete and detailed record of the interview. Despite the difficulties of a limited choice of responses, ambiguities and hidden meanings in the questions, and matters of courtesy, cumulative refinements of the interview will lead, eventually, to a standardized counseling system of known performance.
