ABSTRACT
Objective:To develop the modified medication regimen complexity index of Chinese version (mMRCI-C)and test its reliability and validity.Method:The Chinese version of MRCI was developed by modification,translation and back translation. The MRCI was interculturally adapted by 2-rounds of expert consultation and pilot study to ensure the semantics, content and conceptual equivalence. The validation of the mMRCI-C scale was tested among 420 community-dwelling elderly patients with type 2 diabetes mellitus(T2DM) in Shanghai Changfeng Community Health Service Center from October to December 2020. SPSS 23.0 was used to analyze the reliability and validity of the scale.Results:The mMRCI-C scale included 3 dimensions, namely drug dosage form (14 entries), medication frequency (5 entries), and additional instructions (6 entries), with a total of 25 entries. Among 420 valid questionnaires collected,the respondents were 212 males (50.4%) and 208 females (49.6%) with a mean age of (71.4±8.1) years. The test-retest reliability was 0.999 and internal consistency reliability was 0.849. The content validity exceeded 0.80,the convergent validity was 0.932; and discriminant validity P<0.001. Conclusion:The preliminary testing results show that the reliability and validity of the mMRCI-C scale are satisfactory.
