Inter-rater Reliability and Validity of the Arabic Version of Categories of Auditory Performance-II (CAP-II) Among Children With Cochlear Implant.

BACKGROUND

Categories of Auditory Performance II (CAP-II) is an established audiological test that consists of a rating scale that can be used for prospective assessment of the auditory performance of cochlear implant (CI) recipients.

OBJECTIVE

To create and validate an Arabic version of Categories of Auditory Performance scale II (CAP-II), and to evaluate its reliability.

METHODS

In this cross-sectional study, 30 post-CI children (patients' group) along with 30 control subjects were included. The translated Arabic CAP-II scale has been used by speech-language pathologists and parents to evaluate the study subjects' auditory abilities. The interrater reliability, test-retest reliability, pre and postintervention score (responsiveness test), case versus control score comparison (discriminate validity), and cross-validation of the new Arabic version of CAP-II have been assessed.

RESULTS

The Arabic CAP-II demonstrated high test-retest and inter-rater reliability. There was a positive correlation between the Arabic CAP-II and Meaningful auditory integration scale. The Arabic CAP-II scores were higher in the patients' group compared with control subjects.

CONCLUSION

The Arabic CAP-II showed high inter-rater reliability with excellent concurrent and discriminate validity. The Arabic version of CAP-II seems to be a valid and reliable tool in assessing different auditory performance in Arabic speaking children with hearing impairment.
