Abstract

In the area of health measurement, few guidelines exist for the health professional interested in understanding the concept of reliability. Yet, often there is a need to construct, modify, or select a reliable instrument that will satisfy a particular research or clinical need. This article reviews the concept of reliability and presents a few of the more common techniques used to calculate the reliability of health assessment instruments. Practical guidelines for questionnaire construction and administration are also discussed.
