Reducing bias in trials from reactions to measurement: the MERIT study including developmental work and expert workshop.

Health Technol Assess 2021 Sep;25(55):1-72

Department of Health Sciences, University of York, York, UK.

Background: Measurement can affect the people being measured; for example, asking people to complete a questionnaire can result in changes in behaviour (the 'question-behaviour effect'). The usual methods of conduct and analysis of randomised controlled trials implicitly assume that the taking of measurements has no effect on research participants. Changes in measured behaviour and other outcomes due to measurement reactivity may therefore introduce bias in otherwise well-conducted randomised controlled trials, yielding incorrect estimates of intervention effects, including underestimates.
