Abstract: Questionnaires are versatile tools that allow data to be collected from different respondent groups for a range of purposes. This article outlines the use of questionnaires in orthodontics for research, quality improvement and clinical purposes. We highlight the importance of questionnaire design, particularly choosing the type of response to generate useful data and approaches to psychometric testing to measure validity and reliability. Orthodontic-specific questionnaires that have been developed and tested are summarized.

Clinical relevance: Questionnaires are a useful tool for collecting information about patient concerns, experience and outcomes; this information is essential to improve the quality of care. It is crucial that valid and reliable tools are used to optimize the usefulness of information.
