Getting to know the person: participatory development of the artistic person-centered fotoscope web-app in Dutch nursing homes
To develop a web app version of the person-centered Photo-Activity, which aims to enhance the social interaction between people with dementia (PWD) residing in nursing homes and their (in)formal carers. The Fotoscope app development followed a participatory design process. Qualitative (interviews and focus groups) and quantitative (via the System Usability questionnaire; SUS) data were collected. Phase I and Phase II were about determining user and system requirements and app design. Phase III and IV involved user-test sessions with 4 residents with dementia, 1 informal carer and 2 formal carers, resolving issues, and using feedback to make improvements to the final version. An interactive web app with pages for searching on photo (sub)themes, a digital guide, and a profile page with photo-selection tool, was developed. The user-test with the Fotoscope prototype, showed that residents responded positively to the digital Photo-Activity, and the (in)formal carers reported that the Fotoscope web app was easy enough to use. Improvements and adjustments based on the user-test feedbacks were then implemented to the first version of the Fotoscope. The Fotoscope web app was successfully developed following a participatory design process. It proved successful and easy to use during the user-tests.

Effects of a Digital, Person-Centered, Photo-Activity Intervention on the Social Interaction of Nursing Home Residents with Dementia, Their Informal Carers and Formal Carers: An Explorative Randomized Controlled Trial
To enhance social interaction of residents living with dementia and their (in)formal carers in nursing homes, we examined the effects of a digital, person-centred, Photo-Activity (PA) versus a conversation activity (control). An explorative randomized controlled trial was conducted in 81 resident-informal carer (IC) dyads and 51 formal carers (FC) with three measurements (pre/post-test, 2-week follow-up). Intervention effects were tested using Mann–Whitney U’s, and ANCOVA’s with pre-test scores as covariates. Interaction effects were examined between dementia severity (DS; less/more) and condition (PA/control). A post-test effect was observed in social interaction (INTERACT-subscale: Mood [p = 0.037, ηp2 = 0.07]), with PA residents showing better mood than controls. Residents with less DS showed more positive effects of PA than residents with more DS (interaction effects: INTERACT-subscales Mood [p = 0.017, ηp2 = 0.092], Stimulation Level [p = 0.011, ηp2 = 0.106], and Need for Prompting [p = 0.013, ηp2 = 0.099]). Higher QUALIDEM Positive Affect scores were observed in the PA group, post-test (p = 0.025, ηp2 = 0.082), and follow-up (p = 0.042, d = 0.39). PA FC showed less empathy (IRI; p = 0.006, ηp2 = 0.185;) than controls, but reported getting to know the residents better (p = 0.035, r = 0.299). PA improved mood and positive affect of residents with dementia and led to FC knowing the residents better. Less empathy was observed in FC providing PA, requiring further investigation.

A Digital Photo Activity Intervention for Nursing Home Residents With Dementia and Their Carers: Mixed Methods Process Evaluation
Background: Within the framework of a randomized controlled trial investigating the impact of a digital, psychosocial photo activity intervention for residents living with dementia in nursing homes and their informal and formal carers, a process evaluation was conducted to determine factors that affected the implementation of the intervention and potentially influenced the intervention outcomes. Objective: By tracing facilitators and barriers to implementation, the study also aimed to inform future implementation of the photo activity intervention. Methods: Following Medical Research Council guidance, mixed methods were used to investigate context, implementation, and mechanism-of-impact factors during the photo activity intervention via the Fotoscope web application versus a general conversation activity (control). Google Analytics was set up to gain insight into how the Fotoscope web application was used in practice. For quantitative data, descriptive statistics were calculated and differences between groups tested. For qualitative data, thematic analysis was performed. Results: In total, 163 semistructured interviews were conducted with residents (photo activity group: n=29, 17.8%; control: n=29, 17.8%), formal carers (photo activity group: n=23, 14.1%; control: n=27, 16.6%), and informal carers (photo activity group: n=28, 17.2%; control: n=27, 16.6%). Regarding contextual factors, a minority of formal carers in both groups (photo activity group: 4/18, 22%; control: 9/24, 38%) mentioned time and workload as barriers to implementing the intervention. Regarding implementation, 86% (25/29) of the residents in the intervention group felt that the digital photo activity worked well on a tablet. Informal carers from both groups wanted more intervention updates from formal carers. The majority of formal carers from both groups were satisfied with how the training and activities were implemented. Regarding the mechanisms of impact, residents in the photo activity group (27/29, 93%) felt significantly more positive about the conversations with their carer (U=533.0, z=2.865, r=0.39; P=.004). Formal carers in the photo activity group (20/23, 87%) got to know the resident better (U=390.5, z=2.114, r=0.302; P=.04) compared to the formal carers in the control group (21/27, 78%). Formal carers in the photo activity group (23/50, 46%) gave a significantly higher rating to the digital photo activity as a way of getting to know the resident living with dementia better (median 9.00, IQR 7-9; U=419.0, z=2.169, r=0.307; P=.03) compared to formal carers in the control group (27/50, 54%; median 8.00, IQR 6-8). Finally, the majority of formal carers in the photo activity group (14/18, 78%) agreed that the Fotoscope app can be used as part of care activities in the nursing home. Conclusions: The work invested by formal carers in implementing the photo activity did not seem to differ greatly compared to implementing a general conversation activity, suggesting that the digital photo activity, as an easy-to-implement and enjoyable intervention, could be widely implemented and disseminated in nursing homes.

Can Use of Digital Technologies by People with Dementia Improve Self-Management and Social Participation? A Systematic Review of Effect Studies
There is increasing interest in the use of technology to support social health in dementia. The primary objective of this systematic review was to synthesize evidence of effectiveness of digital technologies used by people with dementia to improve self-management and social participation. Records published from 1 January 2007 to 9 April 2020 were identified from Pubmed, PsycInfo, Web of Science, CINAHL, and the Cochrane Central Register of Controlled Trials. Controlled interventional studies evaluating interventions based on any digital technology were included if: primary users of the technology had dementia or mild cognitive impairment (MCI); and the study reported outcomes relevant to self-management or social participation. Studies were clustered by population, intervention, and outcomes, and narrative synthesis was undertaken. Of 1394 records identified, nine met the inclusion criteria: two were deemed to be of poor methodological quality, six of fair quality, and one of good quality. Three clusters of technologies were identified: virtual reality, wearables, and software applications. We identified weak evidence that digital technologies may provide less benefit to people with dementia than people with MCI. Future research should address the methodological limitations and narrow scope of existing work. In the absence of strong evidence, clinicians and caregivers must use their judgement to appraise available technologies on a case-by-case basis.

Value of Personalized Dementia-Specific Quality of Life Scales: An Explorative Study in 3 European Countries
Measuring Quality of Life (QOL) can be difficult due to its individual character. To explore the value of personalized QOL measurement for people with dementia, personalized versions of two dementia-specific QOL scales (Dementia quality of Life (DQoL) and Quaility of Life in Alzheimer's Disease (QoL-AD)) were constructed. This study investigated whether the personalized measures are more valid to detect variations in QOL than their standard versions for people with mild to moderate dementia, with sufficient internal consistency. Moreover, the relationship between the personalized QOL measures and severity of dementia was investigated. Finally, the study explored the differences between countries regarding the personalized overall QOL and differences in the importance of QOL domains. This explorative one-group design study used baseline data from the MEETINGDEM study into the implementation of the Meeting Centres Support Programme in Italy, Poland and the UK. The personalized versions of the DQoL and QoL-AD were reliable, but not more valid than their standard versions. No relationship between severity of dementia and personalized QOL was found. While no differences were found between countries for the overall QOL score, some QOL domains were valued differently: people with dementia from the UK rated self-esteem, mood, physical health, energy level and the ability to do chores around the house significantly less important than people from Italy and Poland. The personalized versions of the DQoL and QoL-AD may offer dementia care practice important insights into what domains contribute most to an individual’s QOL.
