Anabilim Dalı, Ankara, Türkiye Introduction: The primary aim of this study is to establish the Turkish validity and reliability of the Parent Short Version of Speech Spatial Perception and Hearing Quality Scale (KUİK-E10). The secondary aim is to assess the subjective evaluation of speech perception, spatial hearing, and hearing quality in children who are bilateral (B-CI) and unilateral cochlear implant (U-CI) users, taking into account auditory rehabilitation, family education status, and implant experience duration.

Methods: In the first phase of the study, parents of 100 implanted children aged between 4 and 14 participated to conduct the validity and reliability study of the SSQ-E10 scale. Validity and reliability analyses of the scale included Cronbach's alpha, confirmatory factor analyses, test-retest reliability, and goodness-of-fit indices. After completing the validity and reliability analysis of the scale, in the second phase, parents of 90 B-CI and 37 U-CI children aged between 3 and 15 filled out the scale. Scale scores among groups were evaluated based on auditory education, implant experience duration, and family education status parameters, and correlations and intergroup differences were examined.

Results: The scale, which has a unifactorial structure, yielded a reliability value of Cronbach's alpha 0.936, and RMSEA 0.85. Significant correlations were found between maternal education status, auditory rehabilitation duration, CI experience, and SSQ-E10 score.

Discussion and Conclusion: The SSQ-E10 scale is a valid and reliable tool that can be used in Turkish children with CI. In this study, it was determined that an increase in maternal education status, auditory rehabilitation and CI experience duration, and a decrease in auditory deprivation duration positively affected their skills in speech perception, spatial perception, and hearing quality areas.
