The relatively inexpensive mark-sense paper-and-pencil technique for administering a computer-generated and computer-processed health questionnaire is easy for patients to understand, simple to revise, and permits large-scale testing at low cost. The total questionnaire is designed to be administered in two or more portions or levels. Because each level after the first is a more detailed inquiry into positive responses made to questions of preceding levels, this multilevel approach permits the inquiry to be individualized to the patient. The questionnaires are generated from a question library, and the completed forms are read by an optical scanner. A summary of the patient's responses is printed for the physician's use.
