Validity and reliability of hindi translated version of Montreal cognitive assessment in older adults

To evaluate the validity and reliability of Hindi version of Montreal cognitive assessment (H-MoCA) as a screening tool to detect mild cognitive impairment among older adults of India. The study was conducted in three phases, namely content validation of H-MoCA reliability estimation, internal consistency and test- retest reliability. Qualitative and quantitative validation through expert review resulted in modification of H-MoCA which was tested on purposive sample of 30 subjects, and analysis was done for internal consistency reliability, then the scale was re-administered to the same group to establish test-retest reliability. Internal consistency was reported in terms of Cronbach's alpha (α) and test-retest reliability in terms of intra class correlation coefficient (ICC). Qualitative review and Content validation ratio (Lawshe) validate the content of H-MoCA with CVR of 0.99. The scale has good internal consistency, Cronbach's alpha (α) = 0.64 and high test-retest reliability, intra class correlation coefficient (ICC) = 0.87. Thus the Hindi translated version of MoCA is a valid and reliable tool for detecting mild cognitive impairment.
