  1. N indicates the number of questionnaires returned at each time point; the completeness of data within questionnaires varies; e.g. the overall mean score for the six-item SEMCD/CS-SES scales was available for 741 participants at baseline, 656 at 3 months, 610 at 9 months, 568 at 15 months and 505 at 24 months. The extent of missing data on individual items ranged from 0.8% for the item ‘how confident are you that you can keep the physical discomfort or pain of having had cancer and/or cancer treatment from interfering with the things you want to do?’ at 24 months to 8.1% for the item ‘How confident are you that you can deal by yourself with the problems cancer and/or cancer treatment has caused?’ at 15 months
  2. SD standard deviation, SEMCD Self-efficacy in Managing Chronic Disease, 6 items original Lorig scale (measured at all time points), 11 items original six-item Lorig scale plus five additional cancer-specific items (measured at 15 and 24 months), N/A not available
