aResults in this table are based on seven items (excluding Item 3 relating to lunch-time PA). bThe refined subsample (n = 79) comprised participants from the total sample (N = 110) 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 W value, df, and p value.
