You might think it was a typical therapy session at a long-term care facility. In a quiet room, a therapist sets down a pet carrier, brings out a cat, and sets it on a resident’s lap. As the resident gently strokes the cat’s fur, it purrs, and the therapist asks the resident questions about their childhood pets, accessing long-ago memories.

The resident’s enjoyment of the session and the benefit for their well-being is real. But the animal is not. It’s a robotic pet with synthetic fur and programmed movements and sounds. But researchers are finding that robotic pets can be useful in therapy, without some of the disadvantages and unpredictability of real animals.

In a paper published in the Canadian Journal of Recreation Therapy, University of Utah researcher Rhonda Nelson and graduate student Rebecca Westenskow developed a protocol for using robotic pets with older adults with dementia. The protocol uses a low-cost robotic pet, establishes ideal session lengths, and identifies common participant responses to the pets to aid in future research.

“Our protocol had questions like: Would you like to scratch the dog behind his ears? Would you like to pet him? Would you like to brush him?” says Nelson, an assistant professor in the Department of Occupational and Recreational Therapies.

“And then we were evaluating how people responded to those different cues so that we could then provide some guidelines to people on how to have the most beneficial actions with these animals.”

An affordable robotic pet

Nelson has watched the development of robotic pets for the past decade, intrigued by the potential to use them therapeutically in long-term and geriatric care settings. But until recently the price was prohibitive. “Having been a therapist myself and training our students to work as therapists, I’m very aware that most facilities would never be able to purchase them.”

But with the introduction of Ageless Innovation‘s Joy For All Companion pets in 2015, priced at under $150, widespread use of robotic pets as therapy “animals” seemed within reach. Robotic pets can get around many of the risks and drawbacks of live animals in long-term care settings. Many facilities don’t allow personal pets because of allergies, the potential for bites or scratches and other reasons.

Researchers have already begun to study how people with dementia interact with robotic pets, Nelson notes, but haven’t yet developed a unified protocol to give, say, assisted living staff a plan to gain the most benefit from the pets’ use through directed interaction.

“There was very little information on what people were doing with the pets,” Nelson says. “So without that guidance, it’s just a toy. And what do you do with it?”

Observing interactions

Prior to the COVID-19 pandemic, the researchers met with five people between 82 and 87 years old living in long-term care facilities who experienced severe cognitive impairment. In two sessions of 30 minutes each, the researchers brought out either a robotic dog or a cat (participants’ choice) in a pet carrier.

“Many participants leaned toward the [robotic pet] as it was taken out of the pet carrier,” the researchers noted, “then instinctively reached for it and began petting, rubbing or scratching the pet when first introduced.”

Throughout the session, the researchers asked questions, both about the participants’ experiences with past pets and about interacting with the current robotic pet. “Did they have dogs or cats?” Nelson says, giving examples of typical questions. “What were their names? Did they keep them indoors or outdoors? What types of food did they eat?”

The researchers carefully observed the responses of the participants to the pets. The robotic pets moved and made sounds, which Nelson says helped the participants engage with them.

“When the dog would bark they would say things like, ‘Oh, are you trying to tell me something?’” she says. “Or they would comment on the cat purring and would say things like, ‘Wow, you must really be happy! I feel you purring.’ One of the activities that people responded to the most was brushing the animals.”

In one case, though, the session proceeded in silence. The participant had difficulty communicating their thoughts but stayed focused on the robotic dog throughout. By the end of the session, the participant seemed to develop a connection with the robotic animal, saying “I like that dog. When he likes me.”

Nelson is often asked if the participants with cognitive decline understand that the robotic pets are not alive. In this study, she says, they all seemed aware that it was not a live animal.

“Interestingly enough one of our participants was a retired veterinarian,” she says. “So I was very intrigued to see how he would interact with it.” He chose to have both the robotic dog and cat on his lap at the same time.

“We would never tell somebody that it was live if they asked. We would be honest with them. We usually introduce it as ‘Would you like to hold my dog’ and people react to it or respond to it in a way that’s meaningful for them.”

Initial recommendations

Unfortunately, data collection was cut short by the COVID-19 pandemic. But the researchers were able to draw some conclusions.

All of the participants enjoyed the activity, with several saying they liked it “very much.” One participant didn’t like the sounds the pet made, which was easily remedied by turning off the sound—not an option for a live animal.

The questions that spurred the most response related to personal reminiscences and directions for interacting with the pet.

A common, yet unprompted behavior, the researchers’ report, was communication with the pet. “Several participants used comments, sounds, specific inflections and facial expressions spontaneously with the pets,” the researchers wrote. “Some participants imitated the animal sounds made by the [pet] and repositioned the pet to look at its face or make eye contact.”

Although more research is needed to determine the optimal session length, the researchers noted that the 30-minute sessions in the study were sufficient. Nelson also hopes to explore how people with varying levels of cognitive decline respond to the pets, as well as how they can be used in a group setting.

The study found that the most meaningful interactions and the most enjoyable experiences came when the participant self-directed the session.

“In recreational therapy, we always talk about providing person-centered care,” Nelson says. So it’s not really about what I think about an activity. If somebody enjoys it and it brings happiness to them, then it’s really about what they think about it.”

Why does interacting with robotic pets provide such an enjoyable experience?

“People in long-term care facilities are in a position where everybody provides care to them,” Nelson says, “and to be in the role where you are nurturing something else, or you are the caregiver I think is also psychologically very comforting for people to feel like, even though they know that it’s not live, they’re the person who’s giving love and compassion to something, and it’s responding.”

Abstract

Evaluation of a Robotic Pet Intervention Protocol for Older Adults with Dementia

Interest in the therapeutic use of robotic pets with older adults living with dementia has increased in recent years. Preliminary studies have documented a variety of positive outcomes, but the lack of published intervention protocols and affordable robotic pet models has created a barrier to widespread adoption of evidence-based practices in long-term care (LTC) facilities.

The purpose of this study was to evaluate a robotic pet intervention protocol by documenting participant responses, effective facilitation techniques, participant enjoyment, and session length. During the intervention, participants were given a choice of the cat and dog models of the Joy for All Companion Pets.

The protocol was developed and piloted for use in the memory care unit of a LTC facility. Sessions were facilitated by a recreational therapy professional in participants’ private rooms and each was video-recorded and timed.

Results outline the most common interactive behaviors exhibited by participants, including petting, brushing, holding, and communicating with the robotic pet. Facilitator techniques that promoted engagement included modeling interactions, repositioning the pet, providing verbal prompts, asking questions, and allowing quiet interaction. On a scale of 1-10, participants’ overall rating of enjoyment of the activity was 7.80 (SD = 1.87) indicating they enjoyed the activity “quite a bit.”

They also provided qualitative feedback on elements they liked best or did not like. Session length (M = 30.33, SD = 4.37) data is helpful for future use of this particular protocol. This research represents a step forward in documenting a specific robotic pet protocol for older adults with dementia and illustrating intervention specifics that can be replicated.

Findings offer insight for recreational therapy practitioners wishing to provide evidence-based robotic pet interventions and data to inform future research.
