title: Single-subject evaluation in health education.
abstract: The utilization of single-subject methodology represents a means to improve evaluation efforts in health education. This article provides a rationale for the application of the methodology in health education evaluation. Two variations of the single-subject evaluation methodology (ABAB and multiple baseline) are described. Appropriate methods of data analysis are recommended. Applications of single-subject designs in health education settings are presented. Dilemmas in health education evaluation are identified and reviewed in light of the potential contributions of single-subject methodology.
