  Mildb 124 2.29 (2.29)
  Moderatec 79 4.00 (2.96)

  1. aNo depression.
  2. bMild depression.
  3. cModerate depression.
  4. dSevere depression.
  5. eWelch’s test was computed due to the heterogeneous variance for ANOVA.
  6. fDunnett’s T3 comparison was conducted due to the nonequal variances for post-hoc testing.
