Plain English Summary

Background and study aims
The aim of this study is to explore the effect of dog or robot assisted activities on nursing home clients with dementia. The researchers are specifically interested in what happens during the activities. Do participating clients display less problematic behavior? Do they interact more with either the dog/robot or each other?

Who can participate?
Patients with dementia living in De Zorgboog, a large Dutch nursing home

What does the study involve?
Participants are randomly allocated to attend videotaped weekly group activity sessions with either a dog (and handler), a robot (FurReal Friend, with handler), or a handler only, over a period of 8 weeks. Quality of life, mood and behaviour are assessed during this time period and a 4 week follow-up using questionnaires.

What are the possible benefits and risks of participating?
Participating in this study will provide nursing home clients with an additional weekly activity for 8 weeks providing social contact and the possibility to interact with either a dog or an animal-robot. Interacting with dogs could potentially increase risk of injury, disease or inconvenience due to allergies. These risks have been minimised by using only certified animal-assisted intervention dogs that have been vaccinated and checked by a veterinarian. Furthermore, people with known dog allergies are excluded from participating. The study is also covered by a specific research insurance policy during the course of the intervention period.

Where is the study run from?
De Zorgboog Nursing Homes (Netherlands)

When is the study starting and how long is it expected to run for?
September 2014 to March 2019

Scientific title

Animal-assisted interventions in Dutch dementia care: effects on quality of life and neuropsychiatric symptoms


Study hypothesis

Quality of life and neuropsychiatric symptoms of nursing home clients with dementia are positively influenced by group sessions offering either dog-assisted activities or robot-assisted activities, when compared with a control group.

Nursing home clients are randomised via computer generated random numbers to three groups with protocolled activities:
Group 1: dog assisted activity group sessions with handler
Group 2: robot assisted activity group sessions with handler (FurReal Friend robot)
Group 3: (control): group sessions with a visiting student

Nursing home clients attend videotaped once a week group sessions with a total duration of 8 weeks and a 4 week follow-up. Quality of life, mood and behavior of participating clients are measured using questionnaires.

Intervention type



Drug names

Primary outcome measure

1. Social interaction during sessions
2. Neuropsychiatric symptoms during sessions

Each client will participate in one intervention session a week. All sessions will be videotaped for the entire duration of the study (8 weeks). Videos will be analysed after the intervention period using video-coding to calculate the amount of social interactions and neuropsychiatric symptoms displayed during the sessions.

Secondary outcome measures

Questionnaires will be used to measure several secondary outcomes at all or a subset of the following timepoints: baseline (t0), after 4 weeks (t1, halfway), after 8 weeks (t2, at the end of the intervention period), after 12 weeks (t3, 4 weeks post intervention follow-up):
1. Quality of life, measured using Qualidem at t0, t1, t2, t3
2. Depression, measured using Cornell Scale for Depression in Dementia (CSDD) at t0, t1, t2, t3
3. Neuropsychiatric symptoms, measured using Neuropsychiatric Inventory Questionnaire (NPI-Q) at t0, t1, t2, t3
4. Agitation, measured using Cohen-Mansfield Agitation Inventory (CMAI) at t0, t1, t2, t3
5. Medication usage, measured using medical records at t0, t2
6. Intercurrent diseases, measured using medical records at t0, t2
7. Dementia stage, measured using Clinical Dementia Rating (CDR) at t0, t2
8. Functional state, measured using Interview for Deteriorating in Daily living activities in Dementia (IDDD) at t0, t2
9. Dementia, assessed using Gedragsobservatie Intramurale Psychogeriatrie (GIP, general dementia assessment tool, Dutch) at t0, t2

Results and Publications

Publication and dissemination plan

Results will be published as part of a PhD project in several peer reviewed journals. Publication
should ensue no later than 01/03/2019. The trialists intend to publish the video-coding sheet and study protocol as an online supplement to the publications in a peer-reviewed journal, if the journal in question offers that type of online supplement.

IPD sharing statement
Due to the sensitive nature of the video-material the trialists are obliged under restrictions set by the medical
ethics committee to destroy the video-material after completion of the PhD project. The medical
records and questionnaires of participants will be kept in the medical archive of the nursing home
for 15 years.
