Psychometric Validation

A questionnaire has to be tested for its suitability as a measuring instrument before its general application e.g. the use in clinical trials.

This requirement is not only made on newly developed questionnaires. Psychometric attributes must be proved also for translated versions of existing questionnaires.

Psychometric validation of a questionnaire includes the evaluation of reliability, validity and responsiveness using various statistical methods.
