### Workflow and Intervention Delivery  
Figure 2 showcases the AGAPE workflow, a multi-step approach designed to deliver tailored care and interventions to older individuals. This is achieved through a series of evaluations, profiling, intervention implementation, and feedback for continual learning. The operational workflow of the AGAPE platform is crucial for understanding how interventions are personalised and delivered to the OA. **In-Person Assessment:** The process begins with an in-person assessment, where data about the OA's health, preferences, and needs are collected. This step is crucial for gathering baseline information to build the OA's profile. For this assessment, we have developed a self-assessment questionnaire called the Digital Adoption questionnaire which measures the OA's familiarity and propensity for using innovative solutions [14]. The Digital Adoption questionnaire measures users' familiarity with and propensity towards technology use, focusing on their knowledge, confidence and daily application of technology. Its purpose is to classify users into specific adoption profiles based on their digital health literacy, guiding appropriate training. The questionnaire adapts elements from the Technology Acceptance Model (TAM) [15] and the Unified Theory of Technology Acceptance and Use (UTAUT) [16], integrating insights from [PERSON] et al. (2019) [17] and [PERSON] et al. (2022) [18] to tailor it to healthcare settings. This adaptation includes new components such as Perceived Ubiquity, Self-Efficacy, and Privacy Concerns, enhancing its relevance and accuracy in predicting technology adoption behaviour in the AGAPE context. To measure the efficiency, usability and relevance of the platform, we also deliver three questionnaires, namely the System Usability Scale (SUS) [19] for measuring the overall usability of the AGAPE Assistant, the Technostress [20] to measure the stress experienced by the OA towards the use of technological tools like wearables and mobile applications and the Short form User Experience Questionnaire (SUEQ) [21]. **Questionnaires Repository:** Data from the in-person assessment are stored in a questionnaire repository. This centralised storage ensures that the information is readily accessible for analysis and reference. This repository also contains unstructured information that the Formal Caregivers provide for a specific OA. For example, a specific comorbidity that an OA possesses. **OA Profiling:** Based on the initial assessment data, we combine unsupervised and supervised learning techniques on both quantitative and qualitative data, a profile of the OA is created. This profile helps in understanding the individual's current status based on their needs, capabilities, attitudes and preferences. By categorising users into distinct profiles, AGAPE services can be tuned accordingly, and tailored interventions can be provided to the OA. Each profile is linked to a collection of interventions found in the intervention repository. To enhance the profiling approach, AGAPE utilises data on intervention consumption tracking and feedback gathered from formal carers. **Verifications:** However, before delivering the interventions, the formal caregiver verifies if the assigned profile is relevant. If otherwise, the formal caregiver can modify this profile. After this verification process, the set of interventions to be delivered can be further adjusted. **Set of Personalized Intervention and Goals:** After verification and using the data from the OA's profile, personalised interventions are set along with specific, measurable goals. These interventions could range from physical exercises to cognitive activities, depending on the needs and personal preferences identified in the profiling stage. The interventions are selected from the intervention repository. **Intervention Repository:** The intervention repository holds various intervention plans and strategies that can be employed. These are selected based on the OA's profile to ensure they are well-suited to the individual's needs.
