  1. NWithin = 339; NBetween = 128. Cronbach’s alphas on the diagonal for day-level variables are mean internal consistencies averaged over all measurement points
  2. 1sex coded as 1 = female and 0 = male
  3. 2 For commuting strain ICC was calculated for conventional reporting, but caution is required because of the ordinal scale of this variable
