Wait-list control intervention
cognitive disorders, MCI
Participants in the wait-list control group participated in a 40–60 min health education program on MCI twice a week over 10 weeks. The health education program was delivered by a general practitioner in the community health service center, including instruction regarding cognitive disorders, risk factors related to MCI, healthy eating, and living habits. Participants were also informed that they would receive the P-bM-tACT program after follow-up assessment. Participants were reminded via phone call to complete their education program if missing over two-week. For any questions inquired by the wait-list control group participants, general advice, but not information relating to cognitive training and brain health, was given for ethical consideration.
