This pilot study aimed to compare the effect of companion robots (PARO) to participation in an interactive reading group on emotions in people living with moderate to severe dementia in a residential care setting. A randomized crossover design, with PARO and reading control groups, was used. Eighteen residents with mid- to late-stage dementia from one aged care facility in Queensland, Australia, were recruited. Participants were assessed three times using the Quality of Life in Alzheimer’s Disease, Rating Anxiety in Dementia, Apathy Evaluation, Geriatric Depression, and Revised Algase Wandering Scales. PARO had a moderate to large positive influence on participants’ quality of life compared to the reading group. The PARO intervention group had higher pleasure scores when compared to the reading group. Findings suggest PARO may be useful as a treatment option for people with dementia; however, the need for a larger trial was identified.

To test the effects of individual, nonfacilitated sessions with PARO (version 9), when compared against a look-alike plush toy and usual care, on the emotional and behavioral symptoms of dementia for people living in long-term care facilities. Parallel, 3-group, cluster-randomized controlled trial conducted between June 14, 2014, and May 16, 2015. Twenty-eight long-term care facilities operated by 20 care organizations located in South-East Queensland, Australia. Four hundred fifteen participants aged ≥60 years, with a documented diagnosis of dementia. Stratified by private/not-for-profit status and randomized using a computer-generated sequence, 9 facilities were randomized to the PARO group (individual, nonfacilitated, 15-minute sessions 3 times per week for 10 weeks); 10 to plush toy (same, but given PARO with robotic features disabled); and 9 to usual care. Treatment allocation was masked to assessors. Primary outcomes were changes in levels of engagement, mood states, and agitation after a 10-week intervention, assessed by coded video observations (baseline, weeks 1, 5, 10, and 15) and Cohen-Mansfield Agitation Inventory-Short Form (baseline, weeks 10 and 15). Analyses followed intention-to-treat, using repeated measures mixed effects models. Australian New Zealand Clinical Trials Registry (ACTRN12614000508673). Video data showed that participants in the PARO group were more verbally [3.61, 95% confidence interval (CI): 6.40-0.81, P = .011] and visually engaged (13.06, 95% CI: 17.05-9.06, P < .0001) than participants in plush toy. Both PARO (-3.09, 95% CI: -0.45 to -5.72, P = .022) and plush toy (-3.58, 95% CI: -1.26 to -5.91, P = .002) had significantly greater reduced neutral affect compared with usual care, whilst PARO was more effective than usual care in improving pleasure (1.12, 95% CI: 1.94-0.29, P = .008). Videos showed that PARO was more effective than usual care in improving agitation (3.33, 95% CI: 5.79-0.86, P = .008). When measured using the CMAI-SF, there was no difference between groups. Although more effective than usual care in improving mood states and agitation, PARO was only more effective than a plush toy in encouraging engagement.

To measure and describe the effectiveness of a Virtual Reality Forest (VRF) on engagement, apathy, and mood states of people with dementia, and explore the experiences of staff, people with dementia and their families. A mixed-methods study conducted between February and May 2016. Ten residents with dementia, 10 family members, and 9 care staff were recruited from 2 residential aged care facilities, operated by one care provider, located in Victoria, Australia. Residents participated in one facilitated VRF session. Residents’ mood, apathy, and engagement were measured by the Observed Emotion Rating Scale, Person–Environment Apathy Rating Scale, and Types of Engagement. All participants were interviewed. Overall, the VRF was perceived by residents, family members, and staff to have a positive effect. During the VRF experience, residents experienced more pleasure (p = .008) and a greater level of alertness (p < .001). They also experienced a greater level of fear/anxiety during the forest experience than the comparative normative sample (p = .016). This initial, small-scale study represents the first to introduce the VRF activity and describe the impact on people with dementia. The VRF was perceived to have a positive effect on people with dementia, although, compared to the normative sample, a greater level of fear/anxiety during the VRF was experienced. This study suggests virtual reality may have the potential to improve quality of life, and the outcomes can be used to inform the development of future Virtual Reality activities for people with dementia.

The COVID-19 pandemic poses a threat to global public health due to home confinement policies impacting on physical activity engagement and overall health. This study aimed to explore physical activity participation, health-related quality of life (HRQoL), and levels of perceived stress among Chinese adults during the COVID-19 pandemic. An online survey was conducted between 25 February and 15 March 2020. A total of 645 surveys were completed. Participants reported increased sedentary time from pre-COVID-19 period to the COVID-19 pandemic period (p < 0.05). Over 80% of the sample engaged in either low or moderate intensity physical activity. Participants’ average physical component summary score (PCS) and mental component summary score (MCS) for HRQoL were 75.3 (SD = 16.6) and 66.6 (SD = 19.3), respectively. More than half of participants (53.0%) reported moderate levels of stress. Significant correlations between physical activity participation, HRQoL, and levels of perceived stress were observed (p < 0.05). Prolonged sitting time was also found to have a negative effect on HRQoL (p < 0.05). During such periods of home confinement, public health strategies aimed at educating Chinese adults to enhance home-based physical activity may be necessary to maintain health on a population level.

Maintenance of communication is important for people with dementia living in long-term care. The purpose of this study was to assess the feasibility of using “Giraff”, a telepresence robot to enhance engagement between family and a person with dementia living in long-term care.

Objectives: Social robots such as Paro, a therapeutic companion robot, have recently been introduced into dementia care as a means to reduce behavioural and psychological symptoms of dementia. The purpose of this study was to explore care staff perceptions of Paro and a look-alike non-robotic animal, including benefits and limitations in dementia care. Methods: The study assumed a descriptive qualitative approach, nested within a large cluster-randomised controlled trial. We interviewed a subsample of 20 facility care staff, from nine long-term care facilities in Southeast Queensland, Australia. Thematic analysis of the data, which was inductive and data-driven, was undertaken with the assistance of the qualitative software, ATLAS.ti®. Results: The findings refer to four categories: increasing excitement for Paro and decreasing enthusiasm for Plush Toy; value and function of Paro; opportunities for engagement; and alternatives vs. robustness. Conclusion: Staff caring for people with dementia preferred Paro compared to a look-alike Plush Toy. Staff identified that Paro had the potential to improve quality of life for people with dementia, whereas the Plush Toy had limitations when compared to Paro. However, participants expressed concern that the cost of Paro could reduce opportunities for use within aged care.
