  1. a SRM standardised response mean = mean change in score divided by the standard deviation of the change in scores.
  2. b EC-17 is scored from 0 to 100 where 100 is the best possible score.
  3. c The EAC is scored from 1 to 4 where 4 is the best possible score.
  4. d The BACQ is scored from 1 to 5 where 5 is the best possible score.
  5. e GHQ-20 is scored from 0 to 60 where 0 is the best possible score.
  6. Asterisks denote statistical significance: *p < 0.05; **p < 0.01.
