The adaptation of existing questionnaires is a valuable method to make instruments available in multiple languages. It is necessary to assure the quality of an adaptation by following adaptation guidelines. The Cochlear Implant Quality of Life-35 Profile (CIQOL-35 Profile) was developed and validated to measure the functional abilities in English-speaking adult CI users but is not yet available in German. In this study, we performed a cross-cultural adaptation of this instrument to make it applicable in research and rehabilitation with German-speaking patients.
