title: Multi-matrix sampling: a valuable data collection method for health educators.
abstract: Survey research in health education, as in other disciplines, attempts to provide estimates of population parameters from which inferences important to program delivery can be made. This article examines the utility of multi-matrix sampling as a technique in health education research that permits quality collection of large quantities of data without lengthy questionnaires or excessive time demands on respondents. The advantages and limitations of multi-matrix sampling are delineated through a hypothetical example.
