FAQs

Routine clinical use is generally free of charge, provided the use is not commercially funded or part of a commercial product or service requiring a licence.

Please see our Licensing page for further details.

A licence fee will apply where ICIQ questionnaires are being used for commercial purposes, including commercially sponsored research and some commercial products or platforms.

Please submit a request describing the intended use and we will advise on the appropriate licensing arrangements.

We recommend using each ICIQ questionnaire in its validated form. Selecting individual items, removing questions or changing the questionnaire may affect its measurement properties and the interpretation of its scores.

If you have a specific reason for adapting a questionnaire, please contact us.

Yes. Multiple ICIQ questionnaires can be administered together where appropriate. Each questionnaire should be retained in its validated form and scored according to its own scoring guidance.

ICIQ questionnaires should be used as supplied. Changes to wording, response options, content or scoring are not permitted.

Formatting changes may be made where necessary for electronic administration, provided the questionnaire content is not changed.

If you identify a possible error in an ICIQ questionnaire or translation, please contact the ICIQ team.

Yes. ICIQ questionnaires can be administered electronically, provided the content, wording, response options and overall presentation remain consistent with the validated questionnaire.

Any substantial changes to the way a questionnaire is presented or administered may require additional consideration, particularly where they could affect how participants interpret or respond to the questions.

Commercial electronic platforms may also require an appropriate licence.

Please contact us before developing a new translation. We encourage collaboration on new language and cultural adaptations and have established guidance for translation and linguistic validation.

Where an approved translation already exists, this should be used rather than creating a new translation.

Scoring varies between ICIQ questionnaires. Please refer to the scoring information on the relevant questionnaire page and, where needed, the original validation publication. If the scoring approach remains unclear, please contact the ICIQ team.

Not necessarily. Some ICIQ questionnaires have an overall score, while others are better interpreted using domain scores or individual items. Please refer to the information provided for the individual questionnaire or contact the ICIQ team if you are unsure.

These have been established for some ICIQ questionnaires but not for all of them. Where validated thresholds, severity categories or minimally important differences are available, these should be based on the relevant published evidence.

Please refer to the information provided for the individual questionnaire and associated publications.

Yes, but please contact the ICIQ team before starting this work. We welcome collaborations that contribute to the translation, validation and further development of ICIQ questionnaires.
