The analysis of reliability and validity of the IT-MAIS, MAIS and MUSS

Abstract Objective The aim of this study was to investigate the reliability and validity of the Infant-toddler Meaningful Auditory Integration Scale (IT-MAIS), Meaningful Auditory Integration Scale (MAIS), and Meaningful Use of Speech Scale (MUSS). Methods IT-MAIS, MAIS and MUSS were divided into 3 sub dimensions. 300 children with cochlear implants (CI) were included in the investigation. To assess test-retest reliability of these questionnaires, 30 children were selected randomly to be evaluated at a two-week interval indicated that there were no significant changes between test and retest. Furthermore random test analysis by different evaluators was also administered to 30 users. Results Reliability test: Test-retest reliability of the three scales was proved to be satisfactory. All domains had correlation coefficients that exceeded 0.750(P  Conclusions IT-MAIS, MAIS, MUSS scales have good reliability and validity, and can be used to measure the outcome for children with cochlear implants hearing and speech evaluation.
