Background: New technologies, like socially assistive robots (SARs), may have the potential to support caregivers at home.
Still, the evidence for people with dementia in home care is unclear because a lot of studies are performed in a laboratory or
institutional setting, and mainly use robots in prototype stages.
Objective: This study aims to explore the effects of the refined, commercially-available, humanoid SAR Pepper combined with
a tablet PC–based dementia training program (Coach Pepper) versus an exclusively tablet PC–based dementia training program
on psychosocial and physical outcomes of people with dementia living at home, including caregivers and dementia trainers. We
hypothesize that Coach Pepper has a more positive effect on the primary outcome motivation (stable or decreased apathy) of
people with dementia.
Methods: A mixed methods study will be performed, including a randomized controlled, parallel, 2-arm study with a
complementary qualitative part. This sample includes 40 PWD living at home and 40 relatives, each complemented with five
professional caregivers and dementia trainers. The intervention group will receive Coach Pepper (a SAR connected with a tablet
PC–based dementia training program), and the control group will receive exclusively tablet PC–based training without the SAR.
The duration of the intervention will be three weeks per household. Data will be collected at baseline and during and after the
intervention by standardized questionnaires, sensor data of the robot, and tablet PC, as well as semistructured interviews, focus
groups, and observation.
Results: To date, no results are available for this study protocol. The study intervention started in May 2019 and will end in
Conclusions: The intervention of this study can be seen as a nonpharmacological intervention, including cognitive and physical
training by a robot. This study will help to further refine SAR for the specific needs of people with dementia living at home.
