Abstract
<p>An assessment instrument needs to be valid in order for data to be accurately interpreted and applied. Currently, few rigorous content evaluations have been conducted on hearing-related questionnaires. This study describes a multiphase approach for obtaining content validity evidence in the development of a questionnaire that explores quality of life for persons with hearing loss and their communication partners. A panel of 15 interprofessional experts evaluated 41 questionnaire items for content relevance and content clarity. Findings revealed an overall scale of .99 for content relevance and .85 for content clarity, indicating high content validity for the revised 40-item questionnaire.</p>
