Minimum/maximum	1.00/3.99	1.00/3.46	1.00/4.13	1.00/3.23
Mean	2.19	2.14	2.20	2.16

Median	2.16	2.13	2.20	2.19
Interquartile range	0.76	0.68	0.71	0.76
Skewness ()	2.04	0.87	0.80	−0.52
Kurtosis ()	0.25	−0.24	0.63	−0.98
Normality^c	0.97, 110, 0.029	0.98, 79, 0.200	0.99, 110, 0.417	0.98, 79, 0.315

^aResults in this table are based on seven items (excluding Item 3 relating to lunch-time PA). ^bThe refined subsample () comprised participants from the total sample () who had neither a reduced amount of physical activity nor outlying physical activity scores on either occasion of measurement. ^cNormality results are presented as the Shapiro–Wilk value, , and value.
