Objectives:
Study design and participants:
A convenience sample of 68 pair older adults with MCI/dementia and their informal caregivers from the Chef Anchor 3.0 Programme will be referred to the research team. Overall, participants will be assigned to intervention group and waitlist control group in a ratio of 1:1. Allocation will take into account the participants' availability and the programme capacity. Assessors of outcomes and data analyst will be blinded throughout the whole study.
During the first 10 weeks, the intervention group will undergo the 10-week programme in the "Chef Anchor 3.0", while no activity for the waitlist control group. Then, from week 10 to 20, the waitlist control group will attend the same 10-week programme.
Measurements:
Main outcome measures for people with MCI/dementia will include confidence in cooking (Primary), cooking capability, satisfaction with autonomy in cooking, Satisfaction with meal choices, Worried about future cooking ability and meal choices, cognitive function, self-reported appetite, psychological well-being, family harmony and satisfaction, as well as self-rated health.
Outcome measures for informal caregivers will include confidence in care recipient' s cooking, worried about future cooking ability and meal choices of care recipient, caregiver burden, psychological well-being, family harmony and satisfaction, as well as self-rated health.
Other measures will include attendance rate, home practice rate, drop-out rate, programme satisfaction, and recommendation to others.
