The primary care physicians in the memory disorder clinics at the participating hospitals (Chang-Gung Memorial Hospital at Lin-Kuo, Chang-Gung Memorial Hospital-Taoyuan branch, Catholic Mercy Hospital at Hukou, Hsinchu county) will receive a written letter to explain the purpose of this project and the eligible criteria of PWDs and their FCGs. Debriefing can be provided upon request. Then the participating physicians will help to identify eligible dyads; while one trained research assistant (RA) is responsible for CM implementation (RA I), and the second RA (graduate students, RA II) will be responsible for data collection in each time point.
