   Social relationship Domain 0.47(0.55,0.61,0.53) 0.52(0.60,0.73,0.73) 1

  1. aThe ratio of items to corrected-total correlated (i.e., item to corrected-total correlation) > 0.40
  2. bFor example, for the Physical Domain, 0.39 is the mean (whereas 0.41 is the median) of the 7 item-corrected total correlations for the 7 items within the Physical Domain; whereas 0.29 is the mean (0.34 is the median) of the 21 (7 × 3) correlations between the 7 items in the Physical Domain and the three other Domain scores
