Rating is on a 3-point scale (same or less/better/much better) and scored as 0, 1, 2. Total PEI score is calculated by the average of the scores of the applicable items multiplied by six [ 31].
WFIRS-P domain or total scores were considered invalid if more than 30%% of the item scores used for calculation were missing or 'not applicable' (with the exception of one question relating to siblings, for which a score of 'not applicable' could contribute to the minimum number of items).
For specimens that were uninterpretable or were missing in most of the cancer tissues, a score of not applicable (NA) was given.
For the NDI and NPQ, scores of items not applicable in one particular patient (e.g., driving or reading) are homogeneously distributed among the other dimensions.
Lastly it is possible that a person who has more applicable life domains will have a greater opportunity to experience stigma and this could affect their treatment stigma score, although the use of the mean-of-applicable-items scoring method is likely to minimise any such effects.
To calculate an overall continuous Average Weighted Impact (AWI) score, the weighted ratings of applicable domains were summed and divided by the number of applicable domains [ 17].
For each dimension, the mean distress score was computed as the sum of scores divided by the number of applicable items.
A final score is calculated by dividing the number of positively scored items by the total number of applicable items, and subsequently multiplying the score by 100, resulting in a final score ranging from 0 (no disability) and 100 (all applicable items positive).
The score is calculated by dividing the number of positive scores to the total number of applicable items subsequently multiplied by 100 (0 no disability, 100 all applicable items positive).
We adjusted the total scores for "NA" (by summing the subscores, dividing this score by the total number of applicable items, and multiplying it by the total number of items).
