In Study I, using a cross-sectional data set, normative values for age groups were presented, and age-related changes in each cognitive domain were examined. The results showed that MoCA-J scores declined linearly after 65 years old.
In Study II, we analyzed the results of a 7-year longitudinal study to examine age-related changes in cognitive function using the MoCA-J. As the result, aged 65 to 74 years maintained their scores, and which was considered to offset the repetition effect. In Study III, parallel versions of the MoCA-J were developed to avoid the practice effects when the tests were administrated repeatedly. We found that the repetition effects could be eliminated by administering the parallel versions (version 2 and version 3) after the repetitive administration of the original version.In Study IV, the versions of the MoCA- J for those with visual impairment and with hearing impairment were developed, respectively.
