Measurement and the Measurement of Change [Polit - LIPPINCOTT Williams and Wilkins]

Ideal for graduate-level courses on measurement or research methods, Measurement and the Measurement of Change: A Primer for the Health Professions provides a “gentle” introduction to and overview of complex measurement content. While this primer assumes a basic understanding of statistics and statistical inference, the statistical content serves to enhance conceptual understanding rather than to guide computations. Drawing on measurement theory and approaches from a variety of fields, including psychometrics and clinimetrics, this important work provides unique information for health professionals who develop new instruments, adapt existing ones, select instruments for use in clinical trials or in clinical practice, interpret information from measurements and changes in scores, or undertaking a systematic review on instruments.
