Table 1.

Score statistics and reliabilities (α) at baseline and follow-up.

	Barthel N = 89	SIP N = 407	GO-QOL N = 163
Baseline score (SD, IQR1)	7.98 (4.52, 5–12)	5.12 (6.28, 1–7)	59.32 (24.64, 44–81)
Follow-up score (SD, IQR)	14.25 (5.06, 10–19)	6.13 (7.57, 0–9)	65.22 (24.17, 50–81)
Mean change score (SD)2	6.27 (3.21)	1.01 (4.36)	5.90 (17.13)
SRM3	1.95	0.23	0.34
Chronbach's α time 1	0.86	0.92	0.83
Chronbach's α time 2	0.89	0.94	0.84

1) Distribution of change scores was approximately normal for all three datasets

2) IQR = interquartile range

3) SRM = Standardized Response Mean (see statistical analysis section)
