Measurement equivalence and feasibility of the EORTC QLQ-PR25: paper-and-pencil versus touch-screen administration

Table 2 Exact and global agreements and ICC between touch-screen and paper-and-pencil modes

EORTC QLQ-PR25	Exact agreement^a	Global agreement^b	ICC
Urinary symptoms (8 items)^c	629/791 (80%)	778/791 (98%)	0.78
Bowel symptoms (4 items)	351/396 (89%)	396/396 (100%)	0.72
Treatment-related symptoms (6 items)	500/591 (85%)	574/591 (97%)	0.47
Sexual activity (2 items)	142/196 (72%)	187/196 (95%)	0.61
Sexual functioning (4 items)^d	92/151 (61%)	133/151 (88%)	0.45

Number of total pairs = number of subjects × number of items – number of missing pairs.
^aExact agreement (in%): number of same response pairs/number of total pairs.
^bGlobal agreement (in%): number of within one-difference response pairs/number of total pairs.
^cIn our study, there is no patients reported using incontinence aid, therefore, we deleted an item (US38 “Incontinence aid”) from the Urinary symptom domain, resulting in 8 items remained in this domain.
^dSexual functioning items only apply to sexually active subjects. A total of 48 patients reported being sexually active. Meanwhile, forty-one missing pairs occurred in this domain.
