Hearing disability questionnaires
Reviewed by Joanna Lemanska

This is a very interesting study concerning the validity and readability of 10 hearing disability English language questionnaires available for clinical use. The questionnaires were assessed against the World Health Organisation’s International Classification of Functioning, Disability and Health framework (WHO-ICF). The readability of the evaluated questionnaires was assessed using four commonly used measures including FORCAST. The results showed that the investigated questionnaires differ significantly in reference to the measured categories. Additionally, contextual factors were not sufficiently reflected in all questionnaires. Some of the points covered in the activity limitations and participation restriction category were not reflected in any of the assessed questionnaires. The study also showed that all questionnaires included in the evaluation required a literacy level that is higher than recommended when considering patient reported outcome measures. The results of this study may be very useful both for clinicians and researchers to help in choosing the questionnaire that covers the necessary information in the best way, as well as the best way of administrating it. The presented findings can also be helpful in developing more comprehensive questionnaires with appropriate readability.
