ADL+2.0: Intervention for Prevention of Cognitive Decline in Community-dwelling Older Adults
Sponsor: Tan Tock Seng Hospital
Summary
Singapore's rising dementia incidence with an ageing population presents an urgent need for effective interventions that delay or prevent cognitive decline. While multi-domain intervention studies for dementia prevention show promise, there is a need for an effective personalised approach to address an individual's multifactorial risks for dementia, and to achieve cost-effective, scalable and sustainable outcomes for wider implementation. The investigators propose the ADL+ 2.0 programme, an overall goal is to delay or prevent cognitive decline in at-risk individuals without dementia aged 60 and above with subjective memory complaints and/or impaired cognitive capacity from the ICOPE screening tool. Through a population-level, technology-enabled, community-based preventative approach, ADL+ 2.0 provides remote assessment and multi-component intervention (cognitive training, dual-task exercises, and cognitive wellness) with smart scheduling and personalized intervention, and can be delivered in conjunction with the onsite 6 WELLS facilitated group-based activity, underpinned by the Self-Determination Theory to foster intrinsic motivation for lasting behavioural change. The approach begins with phase 1 test-bedding approach Type 1 hybrid effectiveness-implementation study to ascertain the efficacy, cost-effectiveness, and implementation of the ADL+ 2.0 programme. The investigators will conduct a 3-arm cluster-randomised controlled trial comparing remote/onsite, remote only, and control groups to assess the impact on cognitive outcomes, social networks, quality-of-life and cost-effectiveness. Barriers and facilitators will be identified for implementation, guided by the Consolidated Framework for Implementation Research. Together with NTU-LILY/LKCMedicine as technology partner and community partners (NTUC Health, Fei Yue Community Services, and evaluation partners (GERI/NUS) to provide evidence for and effectively implement a scalable, sustainable, and cost-effective community programme for the prevention of cognitive decline in Singapore.

Combined: Mobile app + 6WELLS
Mobile based digital toolkit for cognitive health, remote assessment and multi-component intervention, comprising the 4 key pillars of assessment; cognitive training and stimulation; cognitive wellness; and dual-task training. Together with onsite 6 WELLS Group-Based Activity is a structured, group-based, cognitive health promotion programme that aims to build communities of practice, stimulate goal attainment, and drive behavioural change towards cognitive health and wellbeing. The curriculum is delivered via a 10-week onsite programme comprising weekly facilitated small-group activities centred on six key components.
