Health Web Te@m (1.0) an Interprofessional Web-based Group Intervention Supporting Healthy Ageing

RAND-36 comprises 35 items covering eight health dimensions: physical functioning, role limitations due to physical health, role limitations due to emotional problems, social functioning, mental well-being, vitality, pain, and general health. Also including a global item assessing perceived health change over the past 12 months. The time intervals vary for different questions: In general, compared to a year ago, current health (a typical day), and the last 4 weeks. The respondent rates the degree of discomfort within the different dimensions on a scale with three, four, five, or six response options, with the exception of two questions that are answered with yes or no.

The OBQ consists of 11 items that are graded on a 4-point ordinal scale from 0-3; these items range from "completely" disagree to "completely" agree and are summed to a total score ranging between 0 and 33. A higher score implies more satisfaction with the amount and variation of occupations, i.e., a higher level of occupational balance. Used to capture the satisfaction with, and the variation in daily activities.

Each item consists of a statement about one's ability to cope with demands in life. The participant rates each item on a scale from 1-4, where 1 represents "disagree" and 4 represents "strongly agree" with the statement; thus, a higher score (total score 10-40) indicates greater self-efficacy. Used to measure self-perceived self-efficacy

Perceived loneliness will be assessed using the UCLA Loneliness scale which is a 20-item scale that assesses three dimensions of loneliness: emotional loneliness, social loneliness, and existential loneliness. Each item is rated on a 4-point Likert scale (ranging from 1, "never," to 4, "often") and the total score can range from 20 to 80, with higher scores indicating greater feelings of loneliness.

LSA-S evaluates an individual's mobility within their environment by assessing levels of movement, frequency of mobility, and the degree of assistance required. The instrument maps movement patterns across five defined "life-space" levels. For each level, frequency and independence are recorded, generating a quantitative total score ranging from 0 to 120.The score for each level is calculated by multiplying the level (1-5) by a frequency factor (1-4) and a factor representing the degree of independence.

These registration forms contain questions about content and delivery for which answers are self-reported on a 5-point Likert scale ranging from very low agreement (1) to very high agreement (5). Older adults will score their level of agreement as follows: a) gain of new and useful knowledge, b) value of reflection assignments, c) value of and engagement in group discussions, and d) use of the digital communication platform. Space is also provided in the registration form to write their own comments.

The pre-intervention questions aim to capture their current everyday activities, what they find meaningful and how they experience their health. Further, their motivators for participation and their expectations of participation in the intervention. Directly after the programme is completed, the interviews will explore experiences of the different parts of the intervention process and the perceived value of the intervention for their everyday activities, social participation and health.

The questions for the group interview before delivery will explore the interest in and motivation to deliver the intervention, expectations of conducting a digital intervention and their role as a group leader. In the group interviews after, the questions will explore experiences of delivering the intervention, compliance with the intervention guide, experiences of their role as a group leader, the digital delivery and time used, and the relevance of the content and the overall value of the intervention. Also, how the education programme prepared them for the delivery of the intervention.
