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

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.

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.
