37 CHAPTER Psychometric properties of the MoCA in healthy participants 2 Table 2.3. Means and standard deviations ( SD ) for the Montreal Cognitive Assessment (MoCA) total (MoCA−TS), domain (MoCA−DS), memory index (MoCA−MIS) and item scores for both version 7.1 and alternate version 7.2, and test–retest reliability (intraclass–correlation; ICC) between versions.
