Questions	Agreement (%) (n = 9)
1. Do you agree with the use of the levels of occupational activities, suggested by a previous consensus group, within the current study? (sedentary, light, light manual, and heavy manual)	100
2. Do you agree with the selected occupation-related tasks within each of the levels of occupation? (see Appendix 3 for list of occupation-related tasks)
Sedentary	100
Light	67
Light manual	78

4. Do you agree with the average durations that have been assigned to the listed activities? (see Appendix 1 for median durations of activities)	89
5. For these duration values, should we use the absolute median number or round it up to the nearest 15 minutes?	67
6. When frequency is missing an assumption will made based on individual activity data from a matched cohort. Do you agree with this assumption? (see Appendix 2 for average frequencies of activities)	67
