Validity and reliability of the Turkish version of the "cochlear implant use questionnaire".

Background: Daily and regular use of cochlear implant (CI) processors is crucial for adapting to them and achieving optimal benefits. However, some obstacles to using CI processors exist, and it is important to identify these barriers and find solutions.

Purpose: This research evaluated the validity and reliability of the Turkish version of the Cochlear Implant Use Questionnaire (CIUQ) related to the barriers to cochlear implant use.

Methods: This is a cross-cultural adaptation of the CIUQ questionnaire. One hundred thirty-four adult CI users aged 18-60 participated in the study. This study evaluated the construct validity of the CIUQ using confirmatory factor analysis and the internal consistency reliability using Cronbach's alpha coefficient.

Results: In the current study, the Kaiser-Meyer-Olkin coefficient was 0.75. The fit values obtained from the CFA applied to the CIUQ were satisfactory and within acceptable limits. Cronbach's α internal consistency coefficient for subscales ranged from 0.70 to 0.78, and the value was 0.8 for the overall scale.

Conclusion: The Turkish adaptation of the CIUQ, which was developed to measure CI usage habits and barriers to daily CI usage, was determined to be a reliable and valid measurement tool for adults using CI.
