ABSTRACT
OBJECTIVE: The aims of this study are to measure the psychometric properties of the newly developed preliminary version of hearing impairment inventory for religious duties for Muslim adults, i.e., the Inventori Persepsi Bagi Muslim Yang Memiliki Masalah Pendengaran (IPM3P), and to produce a final version of IPM3P. METHODS: The preliminary version of IPM3P that is used to investigate the perception of Muslim adults with hearing impairment towards Islamic understanding and practice has been tested in this study. The preliminary version of IPM3P consists of three domains (obligation, practice, and difficulty) with 59 items in total. Four phases of validity and reliability testing involved were: i) Content validation, ii) Pretesting, face validity and proofreading, iii) Pilot study, and iv) Psychometric evaluation. RESULTS: The final version of IPM3P consists of 36 items. The findings from the present study suggest that the final version of IPM3P has excellent psychometric properties manifested by: i) good content validity, ii) excellently pretested, iii) good face validity, iv) good construct validity shown by principal component analysis and convergent validity, and v) good discriminant validity showed by divergent validity. CONCLUSION: IPM3P shows good potential to be used as a tool in investigating perception of Muslim adults towards Islamic understanding and practice.
