It is important for clinicians and researchers to measure outcomes. Patient-reported outcome measures (PROMs) are short questionnaires, which are self-reported and designed to capture a person’s perceptions of specified aspects of their health status.1 Conceptually, PROMs can be viewed either as a ‘tool for evaluation’ or as a ‘mechanism for improvement’ suited to the many factors that characterise a person’s health status that cannot be observed, measured with a device or analysed with even the most sophisticated imaging methods.2 Such questionnaires are ideally suited to areas such as tendinopathy where disease impact does not correlate consistently with biomarkers.

The Victorian Institute of Sport Assessment - Achilles (VISA-A) Questionnaire is a widely used PROM for Achilles tendinopathy and is available in seven different languages (figure 1). The ability of the VISA-A to improve decision making is determined by its reliability, validity and responsiveness to change, as these are essential psychometric properties for any measure.3 4 Here we critically …
