  1. NA not applicable because there is only one item in those key areas, GPAQ-J Japanese version of General Practice Assessment Questionnaire
  2. aThe scaling success rate was calculated as follows: the denominator is the total number of item-scale correlations tested, and the numerator is the number of those correlations in which the items in the scale correlate significantly greater with their own hypothesised scale than with other scales
  3. bSpearman’s correlation coefficient
