An interventional study of Coach Pepper group and Tablet group in Dementia, sponsored by Medical University of Graz. Completed at 1 site in Austria. Per ClinicalTrials.gov, last updated 2024-03-01.
Sponsored by Medical University of Graz · Not applicable, Interventional, and Supportive care
Background:
Dementia rates are increasing worldwide and consequently burden global healthcare resources to a serious degree. However, there is a declining number of caregivers to provide care. It is for this reason that many new technologies, such as socially assistive robots, have been developed because of their potential to support caregivers in promoting the independence of people with dementia.
Most of the (socially assistive) robots have so far been tested for people without dementia in mainly laboratory or in institutional settings, like nursing homes. Consequently, there is a lack of knowledge about the possible uses of robots from the perspective of those affected by dementia in real-life/care situations (e.g. at home). Testing in a laboratory setting cannot capture the complexity and high variability of everyday situations occurring during the care of persons with dementia.
Aim:
The aim is to investigate the effect of a socially assistive humanoid robot on the physical and psychosocial outcomes of caregivers, dementia trainers and persons with dementia living at home.
Methods:
The design is a mixed method randomized clinical trial. As an intervention, 20 persons with dementia and their relatives will receive a socially assistive humanoid robot coach (including a theratainment app for physical and cognitive exercises). The control group (also 20 persons with dementia and their relatives) will receive a tablet including the same theratainment app as in the intervention group, but without the robot.
Data will be collected using sensor data of the robot and the tablet, eye tracking, questionnaires, observation and interviews. There are also questionnaires for the relatives (n=40), dementia trainers (n=5) and professional caregivers (n=5).
Data analysis is quantitative (descriptive statistics, median regression, covariance analysis, wilcoxon rank-sum test) and qualitative (content analysis).
The planned study supports the further development of socially assistive robots with regard to the individual needs of persons with dementia living at home.
2,172 studies on the registry are indexed under Dementia; 540 are open to participants now.

Exclusion criteria:
Persons with dementia:
Pepper is a humanoid socially assistive robot.
Device: Coach Pepper group
Tablet training
Device: Tablet group
Robot Pepper's height is 1.20 meters and it weighs 28 kilograms. Pepper's operation time is about 12 hours. Pepper will be called as Coach Pepper because s/he is virtually connected via web interfaces with a theratainment app including cognitive and physical training .
The Tablet provides a theratainment app including cognitive and physical training.
Change of motivation (persons with dementia)
The "Apathy Evaluation Scale" is a scale to measure motivation because apathy can be understood as a loss of motivation. The scale has 18 items (4-point Likert scale). 18-72 points can be obtained. Higher scores correspond to a higher degree of apathy and therefore lower motivation. Furthermore, sensor data of the robot Pepper/ the tablet will be analysed (usage of different functions).
Time frame: 3 weeks
Change of care burden (relatives)
The "Zarid Burden Interview" captures the subjective burden of caregivers. The instrument has 22 items (5-point Likert scale). 0 - 88 points can be obtained. Higher scores indicate greater caregiver distress.
Time frame: 3 weeks
Change of quality of life (persons with dementia, relatives): The "Dementia Quality of Life Instrument"
The "Dementia Quality of Life Instrument" will be used for the participants with dementia. The instrument has 28 items (4-point Likert scale) in 5 domains (self-esteem: 4 items; positive affect/humor- 6 items, negative affect - 11 items; feelings of belonging - 3 items; sense of aesthetics - 5 items). A global quality-of-life item is also included but does not contribute to the overall score. For every item, 1 to 4 points can be obtained, with higher scores indicating better quality of life. For the relatives, the short version of the "World Health Organization Quality of Life Scale" will be used. It has 26 items and 4 domains (physical health, psychological, social relationship, environment). For every item, 1-5 points can be obtained. In general, higher domain scores indicate a higher quality of life.
Time frame: 3 weeks
Change of care dependency (persons with dementia)
The "Care Dependency Scale" has 15 items (5-point Likert scale). 15-75 points can be obtained. Lower scores indicate a higher degree of care dependency.
Time frame: 3 weeks
Change of mobility (persons with dementia)
The "Timed UP and GO Test" measures the time (in seconds) an individual needs to stand up from a standard arm chair, walk a distance of 3 meters, turn, walk back to the chair, and sit down. Interpretation: \<10 seconds = completely unrestricted; 10-19 seconds = less mobile, but still unrestricted; 20 - 29 seconds = limited mobility; \>30 seconds = pronounced mobility restriction. 14 seconds and more has been shown to indicate a high risk of falls. Furthermore, sensor data of the robot Pepper will be analysed (activity during physical training with the theratainment app).
Time frame: 3 weeks
Change of cognition (persons with dementia)
The "Montreal Cognitive Assessment" has 30 items in 8 domains of cognitive functioning: attention and concentration, executive functions, memory, language, visuoconstructional skills, conceptual thinking, calculations, and orientation. 0-30 points can be obtained. Lower scores indicate a higher degree of cognitive impairment. Furthermore, sensor data of the theratainment app on the tablet will be analysed (performance of cognitive training).
Time frame: 3 weeks
Change of depression (persons with dementia, relatives)
The short version of the "Geriatric Depression Scale" will be used for persons with dementia. The scale has 15 items (yes/no answers). 0-15 points can be obtained. Higher scores indicate a higher level of depressive symptoms. The "Center for Epidemiological Studies Depression Scale" will be used for the relatives. The scale has 20 items (4-point Likert scale). 0-60 points can be obtained. Higher scores indicate a higher level of depressive symptoms.
Time frame: 3 weeks
Technology acceptance (persons with dementia, relatives, dementia trainers, professional caregivers)
The "Technology Usage Inventory" measures acceptance with 9 scales (curiosity, anxiety, interest, usability/user friendliness, immersion, utility, skepticism and accessibility, intention to use) and 30 items (7-point Likert scale). 26-182 points can be obtained (except for the scale "Intention to Use", which is a visual analogue scale with a ten-centimeter-long horizontal line with the two end-points "agree" and "disagree". A cross on the line indicates the degree of agreement. For the evaluation, the distance from the right end-point (disagreement) to the answer cross on the line is measured. This distance (in millimeters) is determined and summed up for all three items (maximum:300, Minimum:0). For all scales, higher levels on the respective scales indicate a higher level of expression in the respective construct. Additionally, individual interviews (people with dementia, relatives) and focus groups (other participants) will be conducted to obtain more in-deep knowledge
Time frame: 3 weeks
Change of usability/acceptance (persons with dementia): semi-structured observation
An open, semi-structured observation of persons with dementia interacting with the robot at home will be conducted by professional caregivers.
Time frame: 3 weeks
Change of affect (relatives)
The "Positive and Negative Affect Schedule" has 20 items (5-point Likert scale) with 2 dimensions (positive affect, negative affect). In total, 20 - 100 points can be obtained. Higher scores indicate higher positive or rather negative affect.
Time frame: 3 weeks
Change of behavioral problems (persons with dementia)
The "Neuropsychiatric Inventory (NPI)" has 12 dimensions (delusions, agitation/aggression, depression, anxiety, elation/euphoria, apathy/indifference, disinhibition, irritability, aberrant motor behavior, sleep and night-time behavior disorders, appetite and eating disorders). Each of the 12 domains is rated in terms of severity (ranging from 0 = absent to 3 = severe) and frequency (ranging from 1 = rare to 4 = frequent). The score of each item is then calculated by multiplying severity by frequency, thus obtaining a score ranging between 0 and 12. The total NPI score is finally obtained by adding all the single item scores (thus, ranging from 0 to 144). Higher scores indicate greater psychopathology.
Time frame: 3 weeks
