Measurement and the Measurement of Change

Ideal 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 undertake a systematic review on instruments, Measurement and the Measurement of Change: A Primer for the Health Professions provides a &quote;gentle&quote; introduction to and overview of complex measurement content that helps ensure high-quality science and excellence in clinical practice.
